ABSTRACT COUNTBRPATTITUDINAL ENCODING EFFECTS ON MESSAGE STYLE AND PERFORMANCE by William James McEwen Experimentation into the research area entitled "counter-attitudinal encoding," through its fecus on attitudinal shift, has largely neglected to undertake a thorough analysis of the communication behavior of encoders. This study therefore addressed itself to an examination of the nature of the counter-attitudinal encoding process, i.e. the message performance and style characteristics which are affected by whether or not a writer agrees with the message output required of him. Research into the effects of psychological stress on communication per- formance/suggests that a general decrement in perfbrmance quality will occur as a result of heightened stress. Assuming that counter-attitudinal encoding requirements generate some amount of stress, this performance decrement should be reflected in a slower rate of message output as well as an increasing number of message errors and changes in counter-attitudinal messages. Research into stress or motivation effects on communication behavior also suggests that a generally lower level of message readability will result from an increase in the stress level under which an encoder is operating. In addition, available research indicates that an encoder's hesitancy or lack of certainty is reflected in the language he subsequently uses. Varying levels of language intensity have been found to be related to the amount of William James McBwen polarity or extremity eXpressed in two principal message elements: verbs and modifiers. It would also appear that certain types of conjunctions reflect the degree of hesitancy present in a message source. Therefore, assuming that encoders of belief-discrepant messages eXperience greater hesitancy about what they are required to write as well as an increase in cognitive stress, specific message consequences would be expected. Counter-attitudinally produced messages should contain language elements indicative of lower expressed intensity than attitudinally-consistent messages. All experimental subjects wrote one message which argued in accord with a previously stated opinion and one message which argued in opposition to this opinion. The order in which these messages were written was contolled for, as was the evaluation of the message topic (i.e. whether subjects wrote on a positively or negatively evaluated topic). ,Message style and performance com- parisons were made between each subject's counter-attitudinal and attitude-con- sistent messages. It was found that encoders made somewhat more errors when arguing counter- attitudinally than they made when writing attitude-consistent messages, although no difference in message output rate was found. Encoders also tended to use less intense language when writing counter- attitudinal messages than they used in their attitude-consistent messages. This language intensity decrement was most evident in the apparent mood (more conditional) and voice (more passive) of the verbs used by counter-attitudinal encoders. No difference was observed in the readability levels of counter- attitudinal vs. attitude-consistent messages. William James McEwen Possible reasons for the incomplete confirmation of the experimental hypotheses are suggested. Research extensions of the present study and impli- cations for future research into the probable impact of counter-attitudinally produced messages on receiver evaluations and exposure probabilities are dis- cussed.

CHAPTER I INTRODUCTION The Problem The area of "counter-attitudinal encoding" has stimulated a large number of studies in recent years (Janis and Gilmore, 1965; Carlsmith, Collins and Helmreich, 1966; Rosenberg, 1966; Linder, Cooper and Jones, 1967). Typically, experimentation has been directed toward the assessment of atti- tudinal effects on an individual who takes a belief-discrepant position. Sub- jects have generally been assigned the task of encoding some "persuasive" message which argues against an attitude which the subject either has previously eXpressed or is assumed to hold. The nature of the encoding task may vary widely. The required message output may be written or oral, may allow anonymity or demand personal identi- fication, or may involve encoding a short outline or a comparatively long essay. The experimental situation itself may require the actual production of a message or merely some public or private commitment to encode. In any event, the actual communication output of such experimentation has customarily been of secondary interest. The primary focus of counter-attitudinal encoding research has been on the change in an individual's attitudinal position after encoding. One result has consistently been found: individuals will alter their initial attitudes to conform more closely to the communication output required of them. Advocacy of a belief-discrepant position somehow results in attitudinal shift in the direction of that position. Much of the available research has set the goal of determining the variables which affect the mag- nitude of this resultant shift. Experimentation has recently centered on the amount of attitude change (so-called "selfepersuasion") as a function of the degree of justification offered (differences in monetary compensation or sponsorship favorability). The result of this inquiry has been the current controversy between pre- dictions of shift based on dissonance theory (Festinger, 1957; Carlsmith et al., 1966) and those based on various incentive theories (Janis and Gilmore, 1965; Rosenberg, 1966). The emphasis on attitudinal shift has led to an almost complete disregard for the nature of the messages actually produced. Some attention has been paid to a few rather gross ratings and measures of communication output. Carlsmith, Collins and Helmreich (1966) used four ratings of essay performance: emphasis used when making points, elaboration and originality, overall quality and per— suasiveness, and apparent effort involved. Linder, Cooper and Jones (1967) looked at differences in one objective measure (number of words per essay) in addition to a number of rating scales (degree of organization, persuasiveness, extermity of position advocated). In neither case did the authors find differences in measures or ratings of message content as a function of justi- fication or incentive. Berger (1968) has provided a summarization of the message analyses which have been performed on communication output by a number of recent researchers. From this summary, it may be seen that there are a number of problems with those studies which have attempted to assess the possible message consequences of counter-attitudinal encoding. Few objective measures have been used. Of the seven studies cited by Berger which used some message analysis scheme, six used an Objective measure. For four of these six, the only reported measure was essay length (number of words per essay). The other measures noted were time spent encoding and number of arguments used. No other objective measures of communication content, perb formance or style were apparently used. In addition, the ratings of message output used by such researchers as Rosenberg (1966) and Linder, Cooper and Jones (1967) have generally been confined to some sort of overall, composite evaluation of message "persuasiveness" or "quality" made by two or three judges. The researchers thus appear to have overlooked a crucial problem. Their studies have not investigated the differences in encoding performance and communication output resulting from an individual being required to assume a beliefediscrepant position -- that is, the message variables which might be affected by differences between an individual's own attitudinal position and his assigned encoding task. i The questions toward which the present study is directed are as follows: How does the process of encoding a counter-attitudinal communication differ from the process of encoding an attitudinally-consistent message? How do people alter their communication performances and styles when writing a.belief% discrepant message? The nature of the material encoded should be affected by whether or not the encoder agrees with the required message output. It seems logical that requiring a person to write counter-attitudinally should result in some departure from his "normal" form of writing. What does an individual do differently when he is writing something he does not agree with -- that is, how does counter-attitudinal encoding compare with attitudinally-consistent encoding? Some probable message and performance differences may be suggested from an examination of related research literature. Psychological Stress: Theory and Research To the extent that the requirements of a counter-attitudinal encoding situation generate some amount of psychological imbalance and stress, results analogous to those of studies of motivation or stress effects on encoding per- formance would be eXpected. It would appear that the inconsistency resulting from compliance with an attitudinally discrepant task induces some ferm of stress. Research has indicated that this heightened psychological stress should then be reflected in an individual's performance. Stress has customarily been conceived of as some deviation from the normal "homeostatic" psychological condition, whether such deviation is brought about by the introduction of psychological or cognitive inconsistency or by various situational factors (extraneous noise, time limitations, etc.). Festinger (1957) has stated that any departure from this normal, balanced state is somehow psychologically uncomfortable and will result in an effort to relieve the dis- turbance. Osgood (1957) has maintained that heightened motivation has both generalized energizing effects and specific cue effects. Therefore, theoretically, psychological stress should lead to certain behaviors designed to lessen this stress. Lazarus, Deese and Osler (1952) have summarized a number of studies relating psychological stress to verbal and perceptual-motor behavior. In most instances, the result of increased stress has been a decrement in performance (in terms of slower reaction times and impairments in the quality of performance). Thus, the general finding has been that stress has debilitating effects on performance. It would therefore be expected that encoding behavior should similarly show evidence of some performance decrement under psychologically stressful conditions. Lynch (1963) has indicated that communication output constitutes a mechanism for tension reduction and stress relief. As such, certain character- istics of a message should be affected by the degree of tension under which the message is produced. If the message production task does serve to reduce tension, this reduction of tension should then be exhibited in the behavior of the individual encoder. Psychological stress should somehow be reflected in an author's communication output. A number of researchers have proposed communication output measures which might be applied to the determination of Specific encoding style and performance variables related to psychological stress. Gynther (1957) reported an index termed "communicative efficiency," a measure of the relevancy of output to the topic assigned. Dollard and Mowrer (19“?) proposed a "discomfort-relief quotient" which was purported to index the general drive or tension state of the encoder (with a greater proportion of "discomfort" statements indicative of higher tension). Boder (19uo) advocated the use of an "adjective-verb quotient" as a measure of time general activity level in a message. These and other objective measures of the drive level present in a communicator were applied in a message analysis conducted by Osgood and Walker (1959). In an attempt to determine the effects of extreme levels of motivation on encoding performance and style, Osgood and Walker examined the message characteristics of suicide notes. The authors, utilizing some of the measures mentioned above, compared suicide notes with ordinary personal letters. Pour general categories of message variables were examined: stereotopy of language, language disorganization, message indicants of the particular drive (self- destruction) operating, and evidence of conflict. Predictions were made in accord with the notions that psychological stress should, in general, have debilitating effects on encoding performance and should, more specifically, give rise to manners of expression which would reflect the psychological im- balance state of the encoder. Osgood and Walker found significant differences in encoding style in three of the four general areas. Suicide notes indicated a higher level of language stereotopy (lower type-token ratios, more repetitions, higher "cloze" scores), thus indicating greater redundancy and predictability of message output. Suicide notes also provided evidence of their authors' heightened drive and conflict states (higher discomfort-relief quotients, greater qualification of verb phrases, more ambivalence constructions and ambivalent assertions). Although Osgood and Walker could find no evidence of structural disorgani- zation (grammatical and Spelling errors), other reserach has provided evidence for expecting some resultant disorganization of message output as a function of stress. Stress Effects on MessageProduction Lazarus, Deese and Osler (1952) have reported studies which indicated a deterioration in verbal production as a result of stress. Increased stress was found to give rise to slower reaction times, longer performance times, and increased errors in production, learning and recall. In addition, Greenberg and Tannenbaum (1962) have investigated the effect of cognitive stress on encoding performance. The authors found that messages produced under situations of cognitive stress (induced by requiring a form of counterbattitudinal encoding from subjects) took longer to encode, and contained more Spelling, punctuation and grammatical errors. Bettinghaus and Preston (196“) also examined the effects of psychological stress on communicators. The authors had subjects encode single sentences in a specified direction (either favorable or unfavorable) with respect to a number of topics. Each subject was required to produce some statements with which he agreed and some with which he disagreed. The authors reported an overall tendency for individuals operating under the pressures of cognitive inconsistency to take more time to encode than those same individuals under cognitively con- sistent conditions. Thus, in summary, messages produced by people under conditions of heightened motivation or tension (due to the introduction of variables tending to increase psychological imbalance) should exhibit certain measurable tendencies which are indicative of an overall performance decrement. The encoding performance itself should take longer (or proceed at a slower rate) and the message output should contain more errors. Language Intensity: Related Research Messages encoded under conditions of psychological stress should also exhibit characteristics which may be said to indicate decreased language intensity. It has been found that prior attitudes influence recall of information related to those attitudes (Klapper, 1960) as well as the subsequent transmission of this information (Allport and Postman, 19u5). It would therefore be expected that prior attitudes should influence any behavior relevant to these attitudes. The process of encoding a message in opposition to an individual's prior attitudinal position should differ from that of encoding a message which is consistent with one's prior beliefs. These differences should be manifested in a greater hesitancy and a lesser intensity in the assertions made by the encoder. It is posited that an encoder who disagrees with what he is saying would be less likely to use emphatic, extreme language than would an encoder who was in full agreement with the views he was instructed to write on. Thus, in addition to the performance characteristics expected to result from the heightened tension accompanying a psychologically stressful encoding situation, the style of the message (in terms of expressed language intensity) should also be reflective of an inconsistency between prior attitude and required output... A number of indices of what may be termed language intensity can be suggested. The level of language intensity in an assertion is partially indicated by the extremity or polarity of the modifiers in that assertion. Howe (1962; 1966), Lilly (1968a; 1968b) and Cliff (1959) have scaled a number of adverbial modifiers in terms of the degree to which they modify the perceived extremity of various adjectives, as judged by a group of receivers. Their results indicated that varying degrees of polarity are expressed by modifiers of the following types: Modifier Type Low Intensity high Intensity Probabilistic doubtfully certainly conceivably undeniably perhaps definitely Intensive slightly extremely somewhat very Frequency rarely repeatedly occasionally frequently sometimes usually Temporal Proximity eventually instantly subsequent 1y immediately Osgood (1959) has proposed a measure of assertion intensity labelled "evaluative assertion analysis." As a method of indexing the degree to which the author of a given message deviates from evaluative neutrality in discussing a concept, the method relies, in part, on the extremity of the modifiers (adverbs and adjectives) selected by the author. Osgood has reported that judges can reliably distinguish between modifiers indicative of polarized or extreme attitudes (:_3 modifiers such as "absolutely" or "extremely") and those which suggest a less extreme position (:_1 modifiers such as "partially" or "somewhat"). Therefore, one index of the degree of favorabllity or unfavorability expressed in a message would be the polarity of the modifiers chosen by the source in assertions related to the message topic. Another message characteristic presumably reflective of the attitudinal position of the source would be the yerb§_used in the assertions made by that source. Osgood stated that "connectors which imply only possible or hypo- thetical relations between actor and complement" are expressive of low (I l) intensity (e.g. "may," "might"). Moderate (1_2) intensity is connoted by most modal auxiliary verb ferms (e.g. "used to," "would," "plan to"). Verb forms indicative of high (1_3) intensity were said to be those in the un- qualified, simple present tense (e.g. "is," "must," "demands"). Another indicator of the source's degree of favorability or unfavorability toward a topic should therefore be the polarity of the verbs contained in the source's communication output. This polarity appears indicable by the general mood of the verbs employed. High intensity language would be marked by less use of conditional, subjunctive verb forms (e.g. "may ," "might," "could," "seems") and a corre5pondingly greater use of the more polarized simple indicative 10 or imperative mood (e.g. "must ," "have to," "is ," "demands ," "has"). The tense of the verb has also been shown to influence the level of perceived favorability in an evaluative assertion. Osgood has reported that the present tense is indicative of higher intensity than the past or future tenses. Holsti (1967) stated thr:the use of the past tense is expressive of a lower level of evaluative intensity than is the use of the present tense. Howe (1966) demonstrated that past and future tenses both connote decreased intensity of connection from that manifested by the simple present tense. The voice of the verbs in a given message has also been found to influence judgments of the activity level of the language used. Johnson (1967), drawing upon some earlier work by Clark (1965), investigated the differences in ratings of terms in active and passive sentences. He found that the use of verbs in the passive voice altered subsequent ratings of the object of the sentence from that obtained when active voice verbs were med. Specifically, the concept being considered by the source was judged as being less dynamic (softer, weaker, less aggressive, less energetic, less potent) under conditions of passive voice verb constructions. In summary, it may be said that variations in the apparent mood, voice and tense of the verb are all indicators of some deviation from evaluative neutrality in a source's treatment of a message concept. Osgood and Walker (1959) have reported a greater percentage of "ambivalence czonstructions" used by encoders under psychological stress. Several of these sample ambivalence constructions ("maybe ," "possibly ," "seems ," "appears") correspond to what has been discussed above as indicants of low language intensity. Others of these constructions ("but," "however") may be viewed in terms of the discussion of message indexing cues put forth by Tannenbaum (1955). Tannenbaum 11 found that the insertion of the conjunction "but" in a message increased the probability that the message would be viewed as a two-sided presentation. It would seem that the apparent two-sidedness of a communication would serve as an additional indicant of the degree of opinion polarization in a source. Greenberg and Tannenbaum (1962) reported an increase in the likelihood of encoding two-sided messages when performing under conditions of counter- attitudinally induced stress. Thus, some index of the amount of polarity, reflected in the use of ambivalence constructions, would appear to result from psychologically stressful antecedents to message production. McEwen and Greenberg (1969a; 1969b) reported that messages containing low intensity modifiers and verb forms were judged to be lower in intensity. These messages were rated as expressive of greater hesitancy, uncertainty and weakness of tone than the same message contan:containing high intensity modifiers and simple, present tense verb forms. Thus, it appears that the . modifiers, verb forms and ambivalence constructions present in a message indicate the apparent intensity level of the attitudinal position of the message source. Since the hesitancy expressed in a message should somehow be reflective of the hesitancy of its author, these language style variables could be used to assess the level of uncertainty and intensity of feeling present in the writer. It fellows that sources required to encode counterbattitudinal arguments should be experiencing some hesitancy as well as some psychological stress or tension. It is the contention of the present study that the communication out- put of an encoder will be affected by the consistency or lack of consistency between the requirements of the task and the encoder's own attitudinal position. 12 Readabilij' Research Gynther (1957) reported that subjects in a high anxiety situation produce more disorganized, disrupted (less "efficient") communication output. This is consistent with Clevenger's (1959) summary of SXperimental research on tension or stage fright effects on Speakers. Clevenger cites research literature which has atteupted to quantify the disruptive effects of tension on communicators. It seems that disorganized communication (e.g. run-on sentences) would be more difficult to understand or comprehend. To this extent, a parallel can be found in the various discussions of what has been termed readability (Flesch, 19u9; Klare, l963). Readability has been proposed as an index of the ease with which potential readers can follow or understand a given message. Readability formulas (e.g. the FleSch measure) basically rely on two measures: average sentence length and number of syllables per hundred words. In applying the prediction that cognitive stress leads to disruption of message output, Greenberg and Tannenbaum (1962) found that counter-attitudinally induced stress led to lower message readability scores. Following exposure to a cognitive stress-inducing situation, individuals encoded messages which con- tained more words per sentence and more syllables per hundred words. Therefore, an additional message style measure which should be affected by the correspondence (or lack of correspondence) between required output and prior attitude would be the readability level of the message. Hypotheses There would appear to be at least two general dimensions along which encoding differences would be expected as a result of inconsistencies between source attitude and required message output: message production variables 13 (variables indicative of the rate and quality of message output) and message style variables (those indicative of differential style, expression or manner of content presentation). Message Production Variables. It is predicted that the introduction of psychological stress or tension (brought about by the counter-attitudinal encoding requirements) will result in a general impairment of encoding per- formance. Hypothesis 1: Hypothesis 2: Message Style Counter-attitudinal encoding will result in Slower rates of message production than will attitudinally-congruent encoding. Counter-attitudinal encoding will result in higher frequencies of message errors and alterations than will attitudinally-congruent encoding. Variables. It is predicted that the writing style of encoders performing a counter-attitudinal task will differ from that of encoders writing under cognitively conSiStent conditions. Hypothesis 3: Hypothesis u: Counter-attitudinal encoding will result in a decrease in the level of language intensity from that obtained under attitudinally-congruent conditions. Counter-attitudinal encoding will result in lower readability scores than will attitudinally-congruent encoding. CHAPTER II METHODS AND PROCEDURES Overview All experimental subjects wrote two messages, one which argued in accordance with and one in opposition to a previously stated opinion. En- coding style and performance variables were compared for each subject arguing counter-attitudinally and attitudinally-consistent, while controlling for order of encoding and attitude toward the issue. Each subject's mood and evaluation of the task was assessed immediately after completion of the required message tasks. Subjects Subjects (N=76) were obtained from an introductory business writing class at Michigan State University. The experimental encoding requirements were Similar to the prior classroom experiences of these students, thus helping to provide motivation for satisfactory task completion. Design and Analysis Two independent variables were used: encoding conditions and topic evaluation.. Each subject wrote messages in each of the two encoding conditions (counter-attitudinal and attitude-consistent). In addition, half the subjects addressed a positively evaluated topic, while the other half encoded messages concerning a negatively evaluated topic. 1n 15 The overall design is in Figure l, with each subject producing two messages, one counter-attitudinal and one attitude-congruent. Encoding Conditions Counter- Attitude- Attitudinal Consistent Positive Topic (Group I) Evaluation Negative (GrouP II) Figure 1. .Message style and performance measures were obtained for each message in each of the four cells. Comparisons in terms of the dependent measures were made between the two encoding conditions. Results were analyzed separately for the two tapics. Procedures. The experiment was preceded by a pretest which determined two suitable issues for the message encoding task. Pretest Procedures. Two weeks befOre the actual experiment, a different group of subjects (N=7u) completed a topic pretest. The pretest consisted of Six Opinion statements accompanied by five-interval rating scales (ranging from "strongly agree" to "strongly disagree"). Subjects indicated the extent of their agreement or disagreement with each statement. From this pretest, two 16 issues were selected for inclusion in the experiment. The topics chosen were the twO most polarized (one most negatively, the other most positively). The most highly favored issue was: "The federal voting age should be changed so as to permit those 18 years of age and older the right to vote." The mean rating of this topic was 3.59 on afive-point scale, with a rating of one indicating strong disagreement and a rating of five indicating strong agreement. The most highly opposed issue was: "Television programming Should be censored by a federal control board." This topic had a mean rating of 2.01 on the same five-point scale. Experimental Procedures. Subjects (N=76) were randomly assigned to one of two experimental groups. Group I subjects (n=l+2) were instructed to encode messages (one message in opposition to the topic and one in support of the topic) which dealt with the "18 year old vote" issue. This was the issue toward which most subjects had expressed a favorable opinion. Group II subjects (n=3it) encoded messages arguing on both sides of the "federal TV censorship" issue, the one toward which subjects had expressed a generally unfavorable attitude. ‘ The order of encoding was counter-balanced in each group. Half the subjects in each topic group encoded counter-attitudinally at time 1 and attitudinally-consistent at time 2. The other half of each eXperimental group followed the opposite order. Before the first encoding task, subjects reSponded to the two concepts selected from the pretest on five evaluative semantic differential scales: good-bad, valuable-worthless, fair-unfair, wise-foolish, and important-unimportant. Only one concept was relevant to a given subject's experimental treatment. 17 Next, subjects encoded the first message required by their topic-condition and order sub-group. Each subject was instructed to write a highly persuasive message which would be capable of convincing potential readers that the subject's assigned position was the more reasonable and justifiable one. The encoding task was introduced as part of a Study on the way people use arguments in attempting to create effective messages of opinion, such as might be found in newspaper editorials. Subjects were given no time limit. The instructions used are in Appendix 1. Subjects then were asked to respond to a number of mood scales (Greenberg, 1960) consisting of Single adjectives accompanied by five-interval rating scales, ranging from "definitely applies to my mood" to "does not apply." Sample mood scale adjectives employed were: "insecure ," "angry," "startled," and "tired." Subjects were also asked to rate the task on two five-interval rating scales ("difficult-easy" and "pleasant-unpleasant"). In the next class period, subjects encoded a message arguing on the opposite side of the issue which they had previously written about. Again, subjects were asked to write as persuasive a message as they felt they could and were permitted sufficient time to complete the task to their satisfaction. Subjects then responded to the same mood and task evaluation scales which had been given at time 1. These instructions are in Appendix 2. Independent Variables Two independent variables were employed in the experiment. These were the conditions (that is, counter—attitudinal or attitude-consistent) in which subjects did their encoding and their evaluation of the topic to be written about (that is, whether subjects had a positive or a negative attitude toward the encoded issue). 18 Encoding Conditions. Each subject wrote both in congruence with and in opposition to his prior beliefS. The experimental measure of attitude toward the topic provided a means of checking the extent of each subject's evaluative polarity with respect to the issue he was writing about. This measure con- sisted of the two selected issues ("18 year old vote" and "federal TV censor- ship"), each accompanied by the five 7-interval rating scales mentioned above. Individual encoding characteristics thus were compared for each subject encoding under the two required encoding conditions. Evaluation of the Topic. Group I subjects encoded messages arguing on both Sides of an issue which was highly favored by these subjects. Group II subjects encoded messages which addressed an issue toward which the majority of subjects had expressed strong opposition. In this manner, individual en- coding Style and perfOrmance variables were then compared for each subject arguing counter-attitudinally as opposed to attitudinally-consistent, while controlling for the direction (positive or negative) of this argumentation. For half the subjects (Group I) counter-attitudinal encoding consisted of writing a proposition-attacking message. For the other half (Group II), the counter-attitudinal task required was that of writing a proposition-supporting message. Control Variable One variable was controlled -- the order in which the messages were encoded. Order of Encoding. The possibility of encoding order effects was con- trolled for by randomly assigning subjects in each experimental group to two alternative encoding-order procedures. Approximately half the subjects in each group wrote counter-attitudinally at time 1 and attitudinally-consistent at time 2. The remaining subjects encoded in the reverse order. l9 DEPENDENT VARIABLES Pe rforman ce Vari ab leS Two major measures of encoding performance were used. The rate of encoding (words per minute) and the number of encoding errors were ascertained for each message produced by each experimental subject. Encoding Rate. Subjects were timed.while performing the encoding task. After having filled out the experimental pretest, subjects all began the encoding task at the same time. Upon completing the message task, subjects were requested to raise their hands. At this time, the mood and task evaluation scales were given to each subject. Experimenters noted the time (in minutes) taken by each subject in writing his assigned message. The length of the message (in total words) produced by each subject was ascertained and the individual encoding rate (in words per minute) was computed. Encoding Errors and Changes. Three indices of the errors or changes made by subjects in the process of message production were employed. The number of Spelling errors and the number of punctuation errors in each message-was determined. In addition, the amount of editing apparent in each message was ascertained. a. spelling errors. The number of spelling errors made by each subject in each message was determined. A spelling error was here defined as any Spelling of a word other than that commonly accepted in a standard English dictionary. b. punctuation errors. The number of gross punctuation errors made by each subject was determined fer each message. Only major errors, such as failure to use periods or question marks when required, failure to capitalize proPerly, and omission of apparent commas and colons were counted. 20 c. editing. The number of occasions of editing within each experimental message was determined. Counted as indices of editing were: cross-outs of words or parts of words, evident corrections or re-tracings of letters or entire words, obvious erasures of words or parts of words, insertions of words or parts of words. Message Style Variables Two major variables were used as indices of the language style used by each encoder. These were the readability of each message and the level of language or message intensity. Readability. The two indices of a message's level of readability originally suggested by Flesch (19u9) are the number of words per sentence and the number of syllables per hundred words. For each experimental message, both indices were computed. The average number of words per sentence was determined and the number of syllables in the first hundred words of each message was ascertained. Language Intensity. The polarization of the modifiers, the use of verb forms and the presence of ambivalence constructions in the messages written by the experimental subjects were measures of the language intensity level of each message. a. modifier polarization. The number of high, moderate and low intensity qualifiers in each message was determined and the proportion of each modifier 'type (per total words) was computed. The following general criteria were used in classifying adverbial or adjectival modifiers. High intensity modifiers were defined as those indicating extreme intensity, probability, frequency or temporal proximity. These were classifiable on the basis of quantitative values reported by Cliff (1959), Howe (1962; l966), Lilly (1968a; 1968b) and Dodd and Gerbrick (1960). Ex- 21 amples of modifiers coded as high in intensity were: "extremely," "definitely," "certainly," "immediately ," and "continually"). In addition, superlative forms of adjectives (e.g. "greatest," "biggest") were considered as highly polarized modifiers. Moderate modifier polarization was reflected in the use of indefinite adverb and adjective qualifiers (such as "much" or "many"), by moderate level probabilistic, intensive, frequency or temporal proximity modifiers (e.g. , "rather," "frequently," "soon"), and by comparative forms of adverbs and adjectives ("bigger," "happier"). Qualifiers of low polarization were defined as those indicating very low intensity, probability, frequency or temporal proximity (such as "slightly,"- "partially," "sometimes ," "conceivably," "eventually"). b. use of verb forms. Three linguistic criteria were used to indicate the level of intensity in the verb forms of a given message. The apparent mood (held to be indicative of the polarity of the verb form), voice and tense of each verb were used to represent some aspect of the degree of definiteness and language intensity in the subject's communication output. (a) verb polarization. The proportions of high, moderate and low polarity verbs (per total words) were computed for each message. Verbs implying conditionality (possibility, potentiality) were considered as ex- pressive of low polarization or intensity. Verbs in the subjunctive mood, compound verbs with the modal auxiliary form indicative of hesitancy or con- ditionality (e.g. "might ," "seems to," "appears to") and verbs in clauses pre- ceded by "if" were classified as low in polarity. Clauses preceded by "perhaps" or "maybe" had the intensity values of the verbs contained in those clauses 22 reduced one level. In such instances, high intensity verbs were reduced to a rating of moderate, and moderate or low intensity verbs were reclassified as being of low polarity. Moderate levels of verb polarity were indicated by qualified indicative mood forms wherein the auxiliary verb was not classifiable as low or high in apparent intensity. Examples of moderate intensity verbs are "ought to," "would" and "should" (that is, verb forms expressive of a higher level of probability and potentiality than that reflected by low intensity verbs), High polarity verbs were those in the unqualified indicative mood (e.g. "to be ," "to have," "to oppose," "to go"), verbs in the imperative mood ("bewardl"), or those accompanied by auxiliary verbs which imply obligation or necessity (e.g. "must ," "demands," "requires"). In addition, negation of several conditional verbs ("can not," "would not") resulted in the verbs being categorized as expressive of high intensity. Complete coding instructions for the classification of the polarity level expressed by both modifiers and verbs may be found in Appendix 3. (b) gigs. The number of passive voice and active voice verbs in each message was determined and an activity ratio (Na/Nam where Na was p’ the total number of active verb forms and Np was the total number of passive verb forms in each message) was computed. (c) 13223.9: The numbers of past, present and future tense verb forms present in each message was determined and the ratio of each verb tense (to total verbs) was calculated. c. ambivalence constructions. The final index of the language intensity level in each message was the proportion of ambivalence constructions 23 (conjunctions of the form: "but ," "Still," "however," "although") per total words . Individual Task and Mood Scale Ratiggg Experimental subjects rated their personal feelings and reactions to their assigned tasks immediately upon completion of each encoding assignment. These measures served as a partial check on the adequacy of the experimental manipulations in inducing stress or anxiety. Mood Scale Rating_. Subjects were asked to complete fifteen rating scales designed to index their mood or feelings when in the act of encoding. These rating scales consisted of Single adjectives accompanied by five-interval rating scales on which subjects indicated the extent to which each adjective applied to their personal mood at the time of encoding (from "definitely applies to my mood" to "does not apply"). Mood adjectives were those used by Greenberg (1960) in assessing the extent of stress among groups of encoders. The author reported that five factors seemed most successful as indicants of cognitive stress. These factors, and the adjectives which best represented them, were: Aggression angry, defiant, rebellious Anxiety: startled, fearful, insecure Deactivation: drowsy, sluggish, tired Social Affection: affectionate, forgiving, kindly Pleasantness: pleased, lighthearted, refreshed Increased stress is presumed indicable by increases in subjects' scores on the aggression and anxiety factors, and decreases on the deactivation, pleasantness and social affection factors. 2') Task Evaluation Ratings. After encoding each message, subjects rated the communication task on two 5-point rating scales: "very pleasant-very unpleasant" and "very difficult-very easy." Readability, A coding form Specifying the rules for classification of language intensity (both in verbs and modifiers) as well as the rules for syllable counts, errors and so forth was constructed, based on the general descriptions provided above. The form may be found in Appendix 3. Inter-coder reliabilities were determined by correlating alternative codings of randomly selected messages. This was done as a partial check on the coding form and the rules for classification. CHAPTER III RESULTS "7 This study examined the effects of counter-attitudinally induced stress on an individual's communication output. It was postulated that an increase in psychological stress would be manifested in specific changes in communi- cation performance and style variables. In comparison with an individual's attitude-consistent performance, it was hypothesized that counter-attitudinally encoded messages would be produced at Slower rates and would contain more en- coding errors. It was further predicted that individuals, when writing in opposition to their prior attitudes, would produce messages which were less readable and contained elements indicative of lower levels of language inten- sity than messages produced by these same individuals under attitudinally- consistent conditions . Each subject wrote two messages. One message argued in accord with a previously stated attitude. The other message argued in opposition to this attitude. Comparisons were made between the individual's performance and Style characteristics under attitudinally-consistent conditions and those measures obtained when the individuals encoded counter-attitudinally. Subject Attrition Subjects (n=20) who wrote only one experimental message (that is, those who did not Show up for part two of the experiment) were eliminated from the 25 26 analysis. The 20 were distributed equally from the two encoding topic conditions. In addition, subjects (n=ll) who, on the basis of the experimental pre- test topic rating, had a neutral attitude (mean rating of u.o over the five 7-point scales) toward their assigned topic were eliminated from further analysis. There did not seem to be any basis for determining which messages were counter-attitudinal and which attitude-consistent for these subjects. Therefore, in the analyses, one group (the "18 year old vote" group) contained 26 subjects and the other group (the "federal TV censorship" group) had 19 subjects. m Reliabilities Forty messages of the 90 total, were randomly selected for either complete or partial recoding in order to assess intercoder reliabilities. The author originally coded all messages, while another coder was trained and did the recoding. At the time of coding, messages were not identified as to whether they had been produced by subjects arguing counter-attitudinally or attitudinally- consistent, so neither coder was aware of the experimental condition for a given message. Also, the second coder was unaware of the experimental hypotheses. The results indicated a reliable coding procedure had been developed. Correlations of alternative codings of each of the nineteen dependent measures , showed relatively high inter-coder agreement in almost every case. With reSpect to the coding of verb and modifier polarity (held to be critical as perhaps having a greater Opportunity for subjective rating), the lowest of the twelve obtained correlations was .815 and eight of the correlations were above .90. 27 Only twice (of 33 checks made) did any obtained correlation fall below .80 (.56“ for numbers of punctuation errors and .605 for numbers of passive voice verbs). In each case, the instances of coder disagreement and coding form ambiguity were discussed and rectified. Repeat correlations on additional sample messages provided acceptably high correlations (.88“ for punctuation errors and .891 for passive voice verbs). Complete listings of the obtained reliability results are found in Appendix 1:. Performance Variables The dependent measures of performance employed were encoding rate and message errors. Encoding Rate. No Specific time limit was imposed on the subjects. Of the total time available in the 50-minute class periods, the maximum time used by any one subject was 38 minutes. This would indicate that little if any time pressure seems to have Operated on the encoders. The mean rates of message production, in words per minute, are in Table 1. There was no significant difference in the rate at which individuals produced messages as a function of the consistency of required encoding performance with prior attitude. Also included in Table l are the mean times to encode, Since subjects arguing counter-attitudinally could have produced messages at the same rate, but for less overall time than when they were producing attitude-con- sistent messages. No Significant differences in total time spent encoding were observed, however. 28 Table 1.

Message Errors. Three main types of message errors and changes were used as indices of the possible effects of counter-attitudinally induced stress on encoding: punctuation errors, spelling errors and editing (cross- outs, erasures, insertions). In addition, an overall error score for each subject was computed by summing across the individual error indices. The re- sults of a correlated t_comparison of subject scores for the four error and change measures appear in Table 2. Overall, in seven of the eight comparisons, the direction of the difference is as predicted, although none of the differences achieve the .05 level of Significance. 29 Table 2.

The difference in individual counter-attitudinal and attitude-consistent message performance with respect to the number of punctuation errors committed per total words was not Significant, although in the predicted direction (p ( .15). 3O Spelling Errors. The counter-attitudinal and attitude-consistent messages did not differ Significantly in the proportions of Spelling errors, although the differences were in the predicted direction. In the case of the proposal of the 18 year old voting age, the probability value of the obtained correlated 3 approached Significance (p_(.10). Editing. No statistical differences in the amount of total editing changes were observed. Total Errors and Chggss. A tendency (p( .15) was again observed for individuals (in both topic conditions) to make more total message errors when arguing counter-attitudinally than when writing messages with which they agreed. Errors_per Minute. In order to determine whether subjects possibly made more errors per unit of time Spent encoding, the total number of message errors and changes made by each subject was divided by the amount of time the subject Spent encoding. The results are in Table 3. In both topic conditions a ten- dency to make more errors per unit of time Spent encoding (py(.lS) was noted when subjects were encoding attitude-discrepant messages. Thus, there seems to be some evidence of performance decrement in terms of error rate (errors per minute) which occurs when individuals' counter—attitudinal.writing perb formances are compared with their attitude-consistent message performances.

No Significant differences in the numbers of words per sentence were found between the message conditions. b. syllables per first hundred words. No Significant differences were noted in the numbers of syllables in the first hundred words of the experimental messages. Language Intensifl. Three chief indices of the level of intensity used by each encoder in writing his two required messages were used: modifier polarization (prOportions of high, moderate and low polarity modifiers), use of 32 verb forms (polarization of encoder language indicable by verb polarity, voice and tense) and ambivalence constructions. a. modifier polarization. Results obtained from the comparisons of individuals counter-attitudinal and attitude-consistent message output are in Table 5. Contrary to hypothesis, no increased usage of highly polar modifiers 7...... was found when the individual subjects wrote attitudinally-congruent messages. An inconsistent pattern was found in the case of low polarity modifiers. Subjects writing on the federal TV censorship issue tended to use more low intensity modifiers when writing in accord with their previously expressed L attitudes (p(.15), whereas it had been predicted that these subjects would use .1_e_§_s_ low intensity modifiers when encoding attitude-consistent messages. Subjects writing on the 18 year old vote proposition, however, conformed more with the experimental hypotheses, with a. tendency (p< .15) to encode more low intensity modifiers when writing counter-attitudinal messages. b. use of verb forms. Three indices of the language intensity present in the verb forms used by each subject are presented below: verb polarization, verb voice and verb tense. (a) verb polarization. Comparisons were made of the extent of each subject's usage of high, moderate and low polarity verb forms, as indexed chiefly by the apparent mood of the verbs contained in the messages produced by the subjects. The findings are in Table 6. As hypothesized, there was a tendency in each topic condition for greater usage of highly polar verb forms by individuals encoding under attitudinally congruent conditions than was observed under counter-attitudinal conditions. In the case of the TV censor- ship issue, this difference was p_(.15. No Significant differences were found in the usage of low polarity verb forms. s". 33 Table 5.

Results of the verb voice comparisons are listed in Table 7. A generally greater proportion of active verbs was used in messages encoded by subjects writing in accord with their beliefs. This trend was found for both the TV censorship issue (p_(310) and for the 18 year old vote issue (p_ <. 20). 35 Table 7.

An inconsistent pattern was found in terms of the verb tense variable, as in Table 8. For subjects addressing the TV censorship proposition, there was some tendency to use relatively more present tense verb forms when arguing in accord with prior attitudes (p_(.20). This trend is as predicted. For the 18 year old vote issue, however, the Opposite tendency was found, with messages encoded under attitudinally-consistent conditions containing somewhat E333 (p_ (.15) present tense verb forms. This latter trend is opposite to the experimental predictions. c. ambivalence constructions. Contrary to expectation, there was apparently no greater usage of conjunctions classifiable as "ambivalence constructions" when individuals argued counter-attitudinally as opposed to attitudinally—consistent. The findings of this comparison are in Table 9. 36 Table 8.

Across the total of 34 possible message comparisons, the differences between the attitude- consistent and counter-attitudinal measures were in the predicted directions in 23 of the cases. Combined Analysis A number of the predicted relationships approached significance. Failure to obtain statistical levels of significance could be due in part to the relatively small number of subjects in each of the topic categories. Combining subjects across these categories could both increase cell size and permit an extended examination of relationships. We subsequently compared the attitude- consistent and counter-attitudinal message outputs of all subjects, regardless of topic category, for the following major perfOrmance and style variables: production rate, total message errors, error rate, high and low polarity modifiers, high and low polarity verbs, active voice verbs, present tense verbs, words per sentence and syllables per first hundred words. The results of this analysis are in Table 10. 38 Table 10.

Of the seven differences with probabilities of less than .25, Six were in the direction hypothesized. One difference reached significance. Subjects made significantly more (p_(.05) errors per minute of time spent encoding when they wrote counter-attitudinally than they did when they wrote attitude-consistent messages. Two of the differences approached Significance. Subjects tended to make more errors per total number of words encoded (p<.15) when writing attitude-discrepant messages. There was also a tendency for subjects to use relatively more (p_(.10) active voice verbs (and, hence, fewer passive verbs) when writing messages with which they agreed. Thus, although the general production rate does not Show the performance decrement usually accompanying increased stress, both total error measures (errors per total words and errors per unit of time Spent encoding) provide evidence that some disturbance of encoding performance has occurred in the situation where subjects are encoding attitude-discrepant messages. Also, there is some support for the proposition that, when arguing counter-attitudinally, subjects use somewhat less intense language than when they are arguing in accord with their prior beliefs. The tendency toward less intense language is evidenced by a decrease in the percentage of active voice verbs used (p<.10). These tendencies, while they do not reach statistical significance at the .05 level, do Show some overall trend in the predicted direction . Sign—Test Analysis There is the possibility that a small number of individuals undergoing relatively large changes could have distorted the results so as to either inflate 40 or deflate the mean group differences. In order to determine the degree to which the changes in each individual's communication behavior corresponded to the experimental predictions, a Sign test (Siegel, 1956) was performed on the data. The results of this additional analysis closely parallel those previously reported. Combining across topic-conditions, four of ..a% nineteen comparisons by Sign test were significant (2‘ .05) and correctly predicted: low intensity verbs per total words, high intensity verbs per total words, active voice verbs per total verbs, and total errors made per minute. Therefore, all variables found to be significant in the parametric analysis of combined topics were Significant by Sign test. The variable of low intensity verbs per total words was significant in this analysis, but not in any of the parametric analyses. Intensifier Ratios Our final analysis compared the percentages in each message of total classifiable modifiers or verbs which were of high or low intensity. Rather than determine the proportion of a given modifier or verb type per total words, it was decided to examine the percentage of verbs or modifiers used which were of a given level of polarization or intensity. In other words, the analysis was designed to ascertain, for example, how often, when the subject used a modifier it was a high intensity modifier or, when the encoder chose a verb it was a highly polar verb. Comparisons of these "intensifier ratios" (proportions of total verb or modifier intensifiers which were of a specific polarity level) were made for each subject's counter-attitudinal and attitude- cOnsistent messages. Comparisons were made disregarding topic-conditions, thus 1+1 permitting the determination of any topic-free trends in counter-attitudinal and attitude-consistent encoding. These results are in Table 11. Table 11.

One difference was statistically Significant. When encoders used verbs, they used more highly polarized verbs in their attitudinally-congruent messages than they did in their counter—attitudinal messages. The mean differences are, however, all consistent with the eXperimental predictions. . V 42 Analysis of Variance Results The use of the correlated 5 test to determine attitude-consistent vs. counter-attitudinal differences may be conservative as perhaps permitting a larger error term than the experimental design actually requires. Thus, treatment by levels by replication 5 tests ("Case II" in Winer, 1962) were done on each of the 24 dependent style and performance measures. The findings F from this three factor analysis of variance with repeated measures are in I Appendix 6 . m—I-Lr n lia' ‘ The results of this additional analysis parallel the t-test findings. With respect to the counter-attitudinal vs. attitudinal-consistent differences, encoders were found to use relatively more verbs per total verbs used (p(.10) and more passive voice verb forms (2 ( 10). No Significant differences were found as a function of encoding order. Several topic differences were noted. However, since there were no controls for degree of positiveness or negative- ness of each issue, or for degree of encoder ego-involvement or topic salience, interpretation of these topic difference findings cannot be conclusive. The discussion chapter further discusses these latter results. Individual Mood and Task Ratiggs Two indices of subjects' individual reactions to the required encoding tasks permitted comparisons of the attitude-consistent and counter-attitudinal encoding situations: mood scale ratings and task evaluation ratings. Mood Scale Ratinji. The differences between individual ratings of their own mood or feelings when writing counter-attitudinal messages and their feelings when writing attitude-congruent messages are listed in Table 12. For neither tOpic condition did the differences in subjects' scores on any of the five \1 v.3 mood factors (aggression, anxiety, deactivation, social affection, pleasant- ness) approach Significance. The data are presented in Table 12 in terms of mean factor scores for subjects within each topic condition. A score of 3.00 would indicate minimum perceived applicability of the adjectives within each factor and a score of 15.00 maximum perceived applicability. Table 12.

CHAPTER IV DISCUSSION Summary The present investigation attempted to assess the effects of cognitive stress, induced by requiring attitude-discrepant communication behavior, upon message output. Hypotheses were based on previous investigations into the consequences of psychological stress on performance and from research relating to language intensity as an indicant of author hesitancy or uncer- tainty. It was generally predicted that a counter-attitudinal encoding Situation would produce measurable deivations from an individual's custOmary (attitude-consistent) encoding behavior in terms of an impairment of encoding performance and a decrement in expressed language intensity. Procedures. Experimental subjects were divided into two groups. One group addressed a.proposition previously found to be a generally favorable one. The second group encoded messages concerning a negatively evaluated proposition. Each subject encoded two messages, one in opposition to his prior attitudes and one in accord with those attitudes. The order in which the messages were encoded was controlled for. There was no time limit placed on the task. Comparisons of encoding performance and style variables were made' between the two messages produced by each encoder. In addition, comparisons were made of the subjects' personal mood and task evaluation ratings. 45 '“h 46 Message Production Measures. No significant difference was found between an encoder's counter-attitudinal and attitude-consistent message production rates. This was contrary to expectation. Subjects arguing counter-attitudinally used no less time and encoded no more slowly than these same subjects arguing in accord with their attitudes. There was a tendency (p (.15) for subjects to make relatively more message errors and alterations when writing counter-attitudinally. Although the differences in numbers of errors made (punctuation, Spelling, editing, total errors) per total words encoded did not reach acceptable levels of significance, the direction in each case was in accord with predictions. In addition, an examination of the rate of error productiOn (per minute of time Spent encoding) showed an overall significantly greater rate of errors for counter-attitudinally encoded messages. Message Style Measures. Contrary to hypothesis, no significant differences or consistent trends were observed for the message readability measures (words per sentences and syllables per first hundred words). According to the measures employed, subjects' counter-attitudinal isages were no less readable than their attitude-consistent messages. \ Limited support was found for the language intensity hypothesis. In terns of the polarity of the verbs used in each message, all analyses Showed a consistent tendency for individuals arguing counter-attitudinally to some- what use fewer high intensity verb forms. There was also, for both tOpics and in all analyses, a tendency for subjects to use relatively fewer active voice verbs (and thus more passive voice verbs) when writing counter-attitudinal messages than when writing attitude-consistent messages 0 47 No difference between counter-attitudinal and attitude-consistent messages was found in the relative numbers of present tense verb fOrms used. Analysis of the counter-attitudinal vs. attitude-consistent message differences in percentages of high and low polarity modifiers per total words and per total modifiers Showed consistent, though not Significant, trends in the expected directions. No Significant difference was found in the usage of ambivalence con- structions as a function of subjects' agreement or disagreement with their required message output. Mood and Task Rating_: No Significant differences in subjects' rated feelings or mood after encoding were observed. For the positively-evaluated topic, Subjects, as expected, rated the counter-attitudinal task as more difficult and somewhat less pleasant than their attitude-consistent task. This difference was not found for subjects writing messages about the negatively-evaluated.proposition. Conclusions. From the data reported, it might be concluded that the theory upon which the experimental hypotheses were based is in error. There are, however, several points which would argue against this interpretation. With respect to the perfOrmance measures, there is some indication that the expectation of performance quality decrement as a function of counter- attitudinally induced stress is warranted. Not only does the prior research noted earlier consistently report such debilitation, the error measures employed in the present investigation all seemingly evidence this general trend. While not attaining statistical levels of significance, the consistency of the findings seems noteworthy. \‘L 48 The data do not provide support for the readability predictions. No Significant differences in encoders' measured readability levels were observed as a function of cognitive stress. There does appear to be, however, at least some limited support for the language intensity predictions. Again, rather than the actual size of the differences, it is the consistency of the direction of these differences which "r " bears mention. The language intensity predictions seem generally to have been born out for the encoders' usage of verb forms. This support is not evident for their use of modifiers and ambivalence constructions. Unresolved Issues Plausible reasons for the failure to completely confirm the experimental predictions will be discussed here. MethodologEal Shortcomings. Three potential areas where methodological problems could have arisen are listed below: individual variance, stress measures and style measures. a. individual variance. One problem lies with the observed variance. There was apparently some greater variation in individual style and per- formance measures as a result of the increaSe in cognitive stress. As may be seen from the standard deviations listed in Appendix 5, in 29 of 47 cases, the variance among individuals arguing counter-attitudinally is larger than the variance observed when these same individuals wrote attitude-consistent messages. This increase in variance across all comparisons is statistically Significant (p = .032, by Sign test). However, in only 2 of 48 such comparisons is there significant heterogeneity of variance. 49 Thus, it is possible that the induction of stress increases the variability in performance and style measures. That is, encoders may become less organized and predictable in terms of their encoding behavior. This increase in variance among counter-attitudinal encoders may mitigate somewhat against the probability of obtaining significant differences. The general trend seems to be in the direction of lower performance quality and decreased language intensity. The increase in within-cell variatiOn, also seemingly a result of cognitive stress, may however be masking the extent of this trend. b. stress measures. One possible problem would seem to be the measure- ment (or lack of measurement) of the stress induction. No direct manipulation check was used, for several reasons. A more adequate check of the success in inducing psychological stress would have attempted measurement immediately after subjects received the counter-attitudinal message task. It was believed, however, that such a measure might contribute more to subjects' perceptions of the artificiality of the artificiality of the encoding situation than it would to the measurement of stress. Because we wished subjects to write as "nor- mally" as possible, and, since the time meaSure from reception of message task instructions to completion of task would have been further complicated by an intervening task, the existence of Stress was assessed only £123 message production. . That decision gives rise to several problems. The encoding process itself may be somewhat stress-reducing, as suggested by Greenberg (1960) and by Lynch (1963). Thus the post-encoding measurement could have been measuring lesser amounts of stress than were actually created by the experimental task. I 50 The instructions attempted to overcome this problem by asking subjects to rate their feelings not as they now felt, but as they had previously felt, when writing their assigned messages. Still, the possibility remained that there was a reduction of stress occurring as a result of the message-encoding process. This might account for the failure to find significant differences in the level of post-message stress. Of more general concern is the adequacy of the instrument itself. The stress measure, originally suggested by Nowlis and Green (1957) and subsequently used by Greenberg (1960) has not been otherwise widely used or accepted as a measure of cognitive stress. This objection might be noted for any measure proposed, however. There seems to be no adequate measure of the internalization of "cognitive stress." The existence of stress is customarily inferred on the basis of the stimuli introduced and the behavior change observed (e.g., Osgood, 1957; Lazarus et al., 1952). There is an apparent lack of consensually accepted, reliable means of measuring stress. c. message style measures. Further methodological considerations exist in the manner in which the style of each message was quantified. There seemed to be no way to avoid the necessity for some subjective decision-making, due to the variables selected for consideration. However, the problem here does not seem to be one of lack of reliability in the measures despite the inherent subjectivity in the measurement of style. The problem rather might lie with the alternative measures which could have also been used. 1'" . .. 5‘." 31." t F! Is "language intensity" best measured by polarity or intensity of modifiers and verbs? What are the relative weights which should be assigned to each element? Are verbs more important than modifiers as indicants of the uncertainty or 51 strength of feeling in a message source -- if so, how much more-2 What of the nouns used by each encoder? No analysis was made of the nouns used, because there appears to be no available scheme for noun classification in terms of evaluative polarity. Although the theoretic prediction of a counter-attitudinally induced decre- ment in language intensity is clear, there seem to be only relatively indirect measures of this intensity. Any number of different measures or ratios might also have been used as perhaps being indicative of language polarity. Perhaps the "concreteness" or "abstractness" of nouns (see Plesch, 1950; Gillie, 1957; Haskins, 1960) bears some relationships to what this study has discussed as language intensity. To the extent that concrete nouns are less ambiguously interpreted by receivers, they may provide an additional index of the certainty or opinion polarization apparent in an assertion. Perhaps the degree of modification of nouns (adjectives/nouns) or verbs (adverbs/verbs) or some combination might also serve as useful indices of the hesitancy expressed in an author's statements. Boder's "adjective-verb quotient" (1940) and Dollard and Mowrer's "discomfort-relief quotient" are additional comparisons which might have been made. An examination of lexical diversity (e.g. extent of common words or of function vs. content words, as discussed by Rommetveit, 1968), a comparison of message "cloze" scores (as proposed by Taylor, 1953) and/or a lock at the usage of personal pronouns (suggested by Ruesch, 1953) would have been other possible considerations. We chose only those measures with some prior empirical basis for expecting a fairly direct relationship with language intensity. This does not rule out the possibility of other, equally important message intensity indices. However, -'- all-r .~..,. ..-.--.,, 3m 3" 52 due to the apparent lack of available research whiCh has systematically linked message elements to receiver judgments of hesitancy, intensity or strength, there has been no satisfactory determination of the most sensitive measures of intensity. Theoretical Problems. All hypotheses were made on the basis of pre- dictions that a certain type of psychological stress (i.e. counter-attitudinally induced stress) would produce Specific, measurable effects on an individual's encoding behavior. The problem at this point is whether or not "stress" was actually generalted by the experimental task requirements and, indeed, whether E ,5 stress is the only, or even the best, theoretic explanation for the observed results. A I" With respect to the first part of this problem (whether stress was actually created), one is forced to argue from the obtained results. There appears to have been a general performance decrement when encoders wrote in opposition to their beliefS. In addition, for one of the two topics, the task evaluation ratings showed subjects perceived the counter-attitudinal task as more difficult and less pleasant. These findings would support the statement that there was greater stress in the counter—attitudinal condition than in the attitude- consistent condition. ' What would appear to be the basis for this stress? It seems reasonable that subjects would know less about the existing arguments which Oppose their onw attitudes. Although there were apparently no fewer total words encoded by subjects when they wrote counter—attitudinally, there may well have been some difference in the numbers or diversity of arguments employed or even in the proportions of content vs. function words used. To the extent that one knows less about what one is instructed to write on, some stress should exist. 53 It also seems that subjects would not be accustomed to writing counter- attitudinally. Perhaps it is the novelty of the task requirements which accounts for the change in writing behavior. This also may be a partial source of the psychological stress posited in the present study. Does an encoder tend to use relatively more low intensity words in a counter- attitudinal Situation because of the Situational novelty or because of some lack FL. of information about the other side? IS low intensity language a result of some personal hesitancy, discomfort or uncertainty which one feels about writing things he does not believe? Does an encoder write less intense messages because stress situations cause one to be less likely to use strong or intense language, or perhaps because of a tendency to encode Statements with which one can more easily agree, as is suggested by "assimilation-contrast" theory (as discussed by Sherif and Hovland, 1961)? It does not appear possible to adequately separate out the more likely of these causes from the less likely, at least in the present study. Perhaps they are not actually separable, given the present measurement capabilities. This may well be a problem for future research and measurement refinement. For the present experiment, one can merely speculate as to the most probable bases for the stress that was apparently generated. Research Impli cations Why study the counter-attitudinal encoding Situation? First, the situation apparently has several "real-life" counterparts. It is not merely a contrived experimental situation. PrOfessional encoders (editorial writers, Speech writers, advertising copy writers) may be assigned a specific task of writing messages with which they do not personally agree. It would seem logical 54 that such an occasion Should result in differences from an individual's more normal encoding behavior. The present study begins to specify some of the probable differences. It appears that an encoder's prior attitudes influence how and what he writes. The people who assign encoding tasks do not customarily take account of the attitudes of the prospective encoders, however. To the extent that professional encoders behave similarly to the way college business writing students do (and this is a subject for. future inquiry), the present Study would provide some support fot the contention that encoders' attitudes Should be c onsidered. These attitudes should be considered, that is, if increased errors and decreased intensity produce a less desirable message, one which conforms less well to the hoped-for communication output. Prior research indicates that messages of the type more likely produced by encoders who do not agree with the output required of them would be less effective. Greenberg and Razinsky (1966) found that increased numbers of Spelling, punctuation and grammatical errors, at least at extreme levels, resulted in decreased evaluations of message logic and clarity as well as decreases in receiver ratings of source competence and trustworthiness. In addition, the authors found decrements in the amount of information gained as a function of high numbers of message errors. McEwen and Greenberg (1969b) reported lower ratings of message clarity and a generally lower evaluation of the meSsage source when receivers rated messages employing low intensity language (low polarity verbs and modifiers). Thus it would seem that the increased errors and decreased language intensity observed as a result of counter-attitudinally induced stress would have some Significant effects on the probable impact that these sorts of messages would have. I! ELK-1' 55 A logical extension of the present study would be an investigation of the effectiveness of counter-attitudinally encoded messages (as Opposed to messages produced by attitude-consistent encoders) among groups of receivers. Do the differences noted in message intensity make a Significant difference to readers of that message? Does the difference in message effectiveness depend upon the potential receivers of the messages? Perhaps audiences who are highly opposed to the message proposal are more persuaded by the less intense messages encoded under counter-attitudinal conditions (as in a "soft sell"). Highly intense messages may be more effective among people who are in agreement with or neutral toward the message proposition. Further research could compare messages on the same Side of an issue, differing only in whether or not the encoders who produced the messages agreed with the message proposition. This might point out the extent to which the observed message differences are meaningful differences, with respect to their effects on attitude change toward source, message and topic as well as their effects on other dependent measures (e.g. comprehension and retention). Messages could also be compared in terms of exposure probabilities. To the extent that language intensity correSpondS to the concept of stimulus intensity, some effect on the amount of initial attention paid to messages in fa voluntary exposure Situation would be expectedaf Again, there would be the Opportunity to assess the meaningfulness of the observed message differences -- are the differences great enough to produce noticeable differences in the probability that receivers will pay attention, either initially or over a period of time, to a given message? As mentioned befOre, much research has been devoted to thedktermination of the factors influencing the amount of selfepersuasion fellowing belief-discrepant 56 communication behavior. Little has been done in the way of analyzing the communication behavior produced. A Specification of the important message variables reflective of individual attitudinal states Should provide correlates which would aid in the investigation of attitude change. For instance, it would be possible to examine the relationship between extent of attitude change (i.e. self-persuasion) and encoding style change. The difference betveen an encoder's attitude-consistent and counter-attitudinal message intensity levels might provide a clue to the amount of personal inconsistency he is undergoing. It may be that larger deviations from normal encoding styles are indicative of greater dissonance and hence greater subsequent attitude change. On the other hand, perhaps greater style deviations provide an alternative mode for the reduction' of inconsistency or dissonance and thus less attitude change could result. An investigation of this research area should thus allow for some pre- dictions of amount of probable attitude change on the basis of observed message style alterations. The present study found Significant differences in encoding style and performance characteristics as a function of the topic on which subjects wrote.’ As reported in Appendix 6, a number of Significant differences occurred between the measures obtained from the encoders writing on the 18 year old vote issue and those writing on the federal TV censorship issue. Due to the lack of suitable controls, any conclusions here must be only tentative. A number of the differences seem attributable to the particular nature of the encoding requirements inherent in theSe two issues. For instance, subjects made more Spelling errors and used relatively more syllables per hundred words when writing messages addressing the federal television censorship proposition. ‘1 I _. E" 57 This seems reasonable merely as a result of "television censorship" being more difficult to Spell and containing more syllables per word than "18 year old vote." What is more interesting is the fact that encoders writing on the TV censorship issue used more low intense verb forms, fewer ambivalence con- structions, more future tense and fewer past tense verb ferns than those writing on the 18 year old vote proposal. The present study did not, however, attempt a systematic examination of encoding differences as a function of message topic. This area seem a subject for future inquiry. There did appear, in the present study, to be a relatively greater tendency to conform to eXperimental predictions among encoders writing on the "18 year old vote" issue. Assuming that this issue was more salient or meaningful for college Students, some future research hypotheses might be generated. Further research might examine messages addressed to different issues, saying in extent of'ego-involvement with either greater or lesser variability in encoder attitude than was presently employed. One might look at differences in messages arguing on mildly polarized or salient topics, as Opposed to the language differences in messages addreSsing highly polarized or salient issues. Thus, it might be possible to determine whether or not topic salience, for example, has an effect on the degree to which individuals modify their encoding performances when writing counter-attitudinally. An examination of the act of writing a positive (proposition-favoring) as Opposed to that of writing a negative (anti-proposition) message could also be undertaken. How does the language intensity level, for example, of an encoder differ when he is writing a negative message from what it is when he is writing a positive message? It may be that individuals generally use more intense 58 language when writing messages of condemnation. Encoders may customarily employ more polarized and emphatic language when they attack an issue than they do when they praise an issue. An examination of the encoding behavior of "neutral" people could also be accomplished. To what extent are the relationships between agreement or disagreement with required output and subsequent performance and style measures linear? IS the language intensity used by a counter-attitudinal encoder less than that used by a person who is neutral toward the message issue? Unfortunately, in the present Study there were an insufficient number of encoders who were neutral toward the two tOpics to permit adequate analysis of this problem. Only through additional research will such questions be answered. It is hoped that the present study at least has provided some impetus toward the research necessary to answer them. I...» ' | .
