Berg_ A THESIS Submitted to the School of Graduate Studies of Michigan State University of Agriculture and Applied Science in partial fulfillment of the requirements for the degree of MASTER OF ARTS Department of Psychology 1959 ABSTRACT The present investigation was concerned with the construction of a sentence completion test to measure the need for affiliation. The purpose of the new instrument was to avoid the content analysis required by the TAT method of measuring affiliation which is used by McClelland et a1. It was expected that the obviation of content analysis would result in a more economical, self-administering, independent research measure of affiliation. The two tests were administered to a sample of 100 neuro-psychiatric aides at Battle Creek Veteran's Administration Hospital. The correlation between the two tests was computed; items of the sentence comple- tion test which elicited the least amount of affiliation imagery were dropped from the test and.this revised form of the sentence completion was correlated.with the TAT. Finally, multiple correlational methods were used to predict the maximal weighting of all items on the sen- tence completion in order to increase the correspondence of this test with the TAT. The final form of the Sentence Completion Test correlated .23 with the TAT, which is significant at the .05 level. However, the overall results of the study suggest a positive, but low relationship between the two instruments. The multiple correlation weights determined from the first half of the sample did not hold up as predictors of the performance of the second half of the sample. The lack of stability of the weights were viewed in terms of a) the small sample size, b) the large number of variables, and c) a basic and inherent difference between the two instruments. A theoretical discussion of projective tests sug- gested possible explanations of the results. The theory of the drive reducing effect of fantasy behavior involved in taking a test and the experimental concept of asso- ciative refractory phase were considered. It was proposed that the method of “validating" or measuring correspondence between two tests by administering them one after the other is nd: a sound psydhological procedure. Limitations of the present sample were considered. ACKNOWLEDGEMENT Grateful acknowledgement is made to Dr. M. Ray Denny and Dr. C.F. Wrigley for their sincere and active interest in this research.

In this test, human motivation is assessed through.content analysis of stories written in response to pictures shown to the subject. Its usage is steeped in clinical-theore- tical points of view. The theoretical basis for the measurement of motivation has been in part provided by Atkinson and Reitmen (3) : Particular motives, (Achievement, Affil- iation, Power, etc.) are conceived of as latent dispositions to strive for certahn goal states (aims) that are mgaged in performance of an act when the cues of the situation arouse the expectancy that performance of an act is instru- mental to attainment of the goal of the motive. The total motivation to perform the act is con- ceived of as a summation of strengths of all the motives that have been aroused by appro- priate expectancies of goal-attainment cued off by the situation. The TAT has provided a means for the assessment of these latent dispositions such as need for achievement, for affiliation, for power, etc. McClelland (10, p. 107) 1 Hereafter referred to as TAT. and his co-workers have written: The choice of the thematic apperception method for collecting data followed from our acceptance of the Freudian hypothesis that a good place to look for the effects of motiva- tion is in fantasy. The Thematic Apperception Test has been developed by Morgan and Murray (1935) for Just this purpose, viz., for bring- ing to light the strivings of the individual in imaginative stories suggested by stimulating pictures. Its popularity as a tool in the clinic may certainly be offered as some evidence of its success in achieving this purpose. One might question at least two features of this statement. First, hypotheses are generally regarded as theoretical prepositions which are acceptable or not according to whether the empirical evidence accords with the deductions which are to be drawn from them. McClelland and his co-workers offer no such empirical evidence in sup- port of the Freudian hypothesis. Their acceptance of it seems to be based upon nothing more than an act of faith, or perhaps an intuitive agreement with it on the grounds of their clinical eXperience. Secondly, popularity is no satisfying evidence of the value of any theory or of any testing instrument. However, the passage is quoted here to illustrate the high regard some well-known psychologists have for the TAT as a measure of human motivation. There are, however, some serious practical and theoretical disadvantages in the TAT. A major one has been the difficulty in validating the test, i.e., in showing that it is really measuring need for achieve- ment, etc. as it purports to do. Another has been the time-consuming nature of the content analysis which is needed to assess the motivational structure of the sub- ject. Both deCharms (S) and McClelland (2, pp. 21;. 25) have stressed the complication of the present system of content analysis and the need for some simpler method of assessment. Before proceeding to outline the present study, the history of need affiliation2 measurement will be outlined, and this will be followed by a review of re- search upon the relations between TAT and sentence com- pletion measures of motivation. T_h_9_ History if; M Affiliation Measurement After the initial work on the fantasy measure of hunger and of need achievement, research was initiated which dealt with g aff. The first attempts to measure 2 eff arose out of Birney's work on the need for secur- ity, which was regarded as not general enough to be a 2:I-Iereafter referred to as g eff. A valid measure of human motivation (13). Shipley and Veroff (13), in 1952, published the results of their studies "validating" n eff. They used two designs: 1) An experimental group was affiliation-aroused before the TAT testing by the administration of a sociometric test; the control group, for their initial activity, received a food preference test. They hypothesized that the affiliation-aroused group would have higher affilia- tion scores on the TAT. 2) The stories of groups of students that had been rejected from fraternities to which they had applied were analyzed. It was hypothe- sized that there would be more n eff scores in this group 's stories than in a group who had been accepted by the fraternities of their choice. In both designs 1 and 2, the results were in the expected directions; in Design 1 the experimental group scored higher on affiliation on 5 out of the 7 categories that were employed and in Design 2 the rejected group obtained higher 3 eff scores than the accepted group, confirming the predictions. A further bit of evidence for the validity of the measure was the negative corre- lation they obtained between popularity as measured by the sociometric test and n eff scores. The theory behind 5 this view of n eff is primarily one of rejection and in fact, Shipley and Veroff (13) defined n eff in terms of separation anxiety resulting from the separation of a person from objects of affiliation. This conceptuali- zation has been revised by Atkinson, Heyns and Veroff (2) in 19514. who came out with a broader definition of 3 off: Any evidence of concern over establish- ing or maintaining a positive affective re- lationship with another person(s) (in addi- tion to concern over restoring broken rela- tionships) is viewed as symptomatic of moti- vation to affiliation according to the present results. Atkinson, Heyns, and Veroff (2) conducted a similar study to Design 1 of the Shipley and Veroff (13) study. Similarly, they had their experimental group partici- pate in the sociometric ratings in the fraternity, but the control group had their non-affiliative related task administered in a classroom setting rather than in a fraternity dining room as the Shipley-Veroff control group had. Furthermore, the pictures that were used were assumed here to be more every-day like, as opposed to the Shipley-Veroff pictures which appeared to elicit stories of basic interpersonal problems. The combination of the more clearly differentiating testing conditions and the more "natural" pictures, combined with the broader scoring system, yielded a significant difference between the two groups, thus producing a broader scoring conceptualization of g aff. Evaluation of; the Characteristics 2f the TAT 5nd t_h_e_ Sentence Completion _l_‘e_s_t_§ A Sentence Completion Test has been suggested to be similar in function to the TAT. Better (12, p. 296) for example, has stressed the apparent similarity of the two methods : When used for clinical purposes, the sentence completion method is very similar to the Thematic Apperception Test. That is, it tends to give information of person- ality content rather than personality struc- ture. It deals with feelings, attitudes, specific reactions to people and things, rather than providing a so-called underlying personality structure. Rohde (11) has similarly regarded the Sentence Com- pletion Test as a projective technique: The sentence completion device in which the subject is asked to read to himself the forepart of a sentence and to write anything he wishes to complete the sentence is essen- tially a projective technique utilizing free association. The possibility would therefore seem to exist of developing a sentence completion test for n aff” measur- ing much the same thing as the need affiliation score on the TAT. The new test would be self-administering, so that a skilled administrator would not be needed; and less time would be required for the test. Such a test, if secured, would therefore be of greater economy, utility and research value than the TAT. The purpose of this study was to try to develop such a sentence completion test of n eff. If this second measure of need affiliation can be developed, and the TAT measure of g aff is found to correlate highly with it, we thereby get some assurance at least about the general- ity, if not the validity, of whatever psychological function is measured by the TAT score. If, on the other hand, little or no correlation is found between the two intended measures of n eff, it will serve as a reminder of the specificity which may possibly be characteristic of certain projective tests. Regegch Upon TAT m Sentence Connletion Measures 2;: Motivation Many investigations have already been concerned with finding the relations between the TAT measures of motivation and those provided by other standard tests such as Sentence Completion and the Rorschach tests. In gen- eral, the correspondence of the various instruments has not so far been demonstrated. we shall now review some of these studies. Although McClelland (l, p. 31) says that the only response system.which.has been extensively explored to date for unique motivational effects is organized fantasy in stories, there have been many attempts not only independently to develop new'instruments, but efforts directed towards "validating” popular standard tests like the Sentence Completion and the Rorschach with the TAT measures of motivation (9, p. hll; 10, pp. 25k. 255) . Other alternative methods, seeking to avoid the content analysis of stories and/or the verbal factor which might be limiting the validity of this method have been reported, i.e., Graphic Expression Test by Aronson (1, Ch. 17), French's Test of Insight (1, Ch. 16), deCharms' Self-scored Projective Measure of Achievement and Affiliation Motivation (5). and others (6, 8). we shall new review some of the studies which have employed sentence completion tests in relation to TAT, either for direct comparison of the two instruments or for a variety of complementary purposes. As far back as 19113. Sanford (11, 12, p. 299) utilized a 30 item sentence completion test in order to measure need action patterns among children. The data were analyzed according to the Murray need-press system of personality description and when combined with data from a ”Completions of Pictures Test,‘ and an "Interpretations Test," it appeared to Sanford that they revealed consistent patterns of responses in many areas. Unfortunately, Sanford did not submit his data to any quantitative analysis. In 1914.6, Rohde (12, PP. 299. 300) published results of a study using a 61.]. item sentence completion test. She also analyzed the data in terms of the Murray sche- ma of needs, press, inner states, and cathectic objects. Wheeler (12, p. 298) used a variation of the sen- tence completion, via, a “Similes Test" where subjects were presented with a list of adjectives and responded with similes of a similar nature. Again Murray's con- ceptual framework was used. McClelland (10, pp. 2511-257). in describing a study by Holzberg using a 50 item sentence completion test, 10 says: Another rather commonly used instru- ment for getting at an individual's per- ception of the world is the Sentence Com- pletion Test. For us it has the added advantage of being another so-called 'pro- jective technique,’ the results of which could be conquered with those obtained with the picture-story or TAT projective method. However, results of the two tests showed very little agreement, and McClelland proceeds: The fact of real importance that emer- ges from this study is that the Sentence Completion Test gives results which differ from those given by the thematic appercep- tion method and which are more in line with conscious self-judgments. Bron and Auld (6), in a 1951.1 study to investigate the effects of confinement aboard a submarine for 30 days, measured personality variables both by the TAT and a Sentence Completion Test. On the qualitative level, they professed to find similar personality trends reflected in both measuring instruments, and accordingly suggested that similar variables were measured through the use of either test. Indeed, perhaps their most val- uable contribution may have been some of the critical insights about the nature of the TAT and its limitations 11 which were revealed in the process of this research. (See P.38). However, as in Sanford's study (11), there 'was no quantitative evidence supplied in support of their position. Lindsey and Heinemann (8), compared the TAT results with those of a 100 item.Sentence Completion Test (an adaptation of the OSS scale), with questionnaire answers, and with scores on the MMPI, as part of their work on developing group-admhnistration techniques of the TAT. The correlations were mostly positive but low. Lindzey and Heinemann.tried to explain the results of their study on the basis of imperfect scorer relia- bility and the theoretical notion of levels of assess- ment.Reliability coefficients on the TAT ranged from..60 to .93. and on the sentence completion from .62 to .85. The authors argued that with the lower reliability coeffi- cients, quite a high percentage of the variance was not accounted for and that this factor might minimize corre- lations with the other measures. They suggested further- more that the measures might be assessing motivation at different levels. Introduction of this concept of assess- ment levels does not, however, provide any conclusive explanation. At the most, it offers suggestions for 12 research to explore... French (1, Ch. 16) developed a lO-item "Test of Insight" which.was hypothesized to offer subjects an Opportunity to make responses relevant to their parti- cular needs. A sample statement is, "Bill always lets the 'other fellow' win" (1). The subjects were asked to respond to each statement in terms of an explanation of why each.man behaves as he does. The subjects' scores ‘were correlated with observational judgments of motiva- tion and goal attainment for both 'affiliation' and 'ach- ievement' and also with.their performance on a question- naire. The correlation between the Test of Insight and the observational judgments ranged from.-.05 to .05. The correlations between the Test of Insight and the ques- tionnaire were .18 and .19 (significant at the 5% level) for the need affiliation variable. The content of her test seems to be similar to a sentence completion form, except that there is a greater latitude of response pos- sible with her items. Feshbach (1, Ch. 11), investigating the drive-reducing function of fantasy behavior, used a.slightly modified version.of the RotterJWillerman Sentence Completion Test as another measure of aggression to be compared with the 13 TAT measure. He reported that the sentence completion test was sensitive to the arousal of aggression in the experimental condition, and.yielded significant differ- ences between experimental and.control groups. One of the possible implications here is that the sentence come pletion test can be ”validated" through the use of ex- perimental arousal, which is the primary method that has been used in validating the TAT-type method of motive measurement. (For a further discussion of this, see p.357. McClelland (1, p. 3h), after reviewing much of the evidence in this area, draws the following conclusions: 0n the other'hand, if the verbal one is a.portion of a sentence which the sub- ject must complete, the content of his come pletions is not related to the content of his stories to the pictures. Perhaps this reality component is larger in the sentence- completion than in the picture-story or "motive-insight" methods. Although.really systematic work in this area.has not been completed, the safest practical generaliza- tion appears to be that cues will tend to be equivalent so long as they suggest vaguely the content area of the motive being measured but do not elicit strong or specific associations based on.particular cultural or personal past associations. This generalization, in and of itself, does not seem to warrant predicting that sentence completion tests will not be tapping similar sorts of information as the TAT. I: 1h the fact that there is more conscious control on the former is not a major detriment to correspondence of the two tests, then we feel that there is enough similarity in their appar- ent nature to warrant further exploration, i.e., both tests deal with personality content (see p. 6 ). Secondly, both re- quire the subject to offer the linguistic responses that he has available. With.reference to the latter, Solomon and Howes (15) have said: ...it follows that in perceptual experiments in which linguistic responses are elicited from.hu- man subjects, 'any variable that is a general pro- perty of linguistic responses must also be a property of any perceptual concept that is based.upon these responses'... Also McClelland reports (9, p. All): we have found that n Achievement score is sig- nificantly related to the kinds of linguistic cate- gories that a person uses in attempting to express himself at least in an achievement related situae tion, and so forth. Certainly there is not enough conclusive research in the entire motivation assessment area which allows for the formu- lation of precise statements of relationships between test: and/or variables. In the course of examining the correspondence between the newly designed sentence completion test and the TAT, statisti- cal procedures will be used to eliminate those sentence comple- tion items which are not effective in eliciting affiliation imagery. A multiple correlational analysis based upon the pre- dictive value of the individual itemm will indicate the items to be retained or dropped. This is likely to be more sound than the "hunches" involved in intuitively dropping items. 15 METHOD Apparatus TAT- In this study data for need achievement, need power, and need.affiliation were collected al- though only the §_aff data are relevant to the present design. A set of six TAT pictures used in a national survey study conducted by the Survey Research Center, University of Michigan, and developed by Joseph Ver- off (1, p. 836) was used. It consisted of pictures 2, 101, 102, 28, 83, and 103 which are described in Appendix III of Atkinson's book, ”Motives in Fantasy, Action and Society"(l)."l A study is currently being conducted on a nation-wide representative sample which should provide normative data, but which.will not be available for a few months. (Personal communication from Dr. Veroff). Sentence Completion- The second test used was a sentence completion test consisting of 61 items: 1 blind 'neutral' item.for practice and demonstration, 20 affiliation items, 20 achievement items and 20 power items. The compilation of the 20 g'aff items was as h Reitman and Atkinson (l, p. 36) recommend multimotive scoring of the same pictures because it has been shown that there is no correlation between achievement and affiliation scoring. 16 follows: Murray Melbin, an advanced trainee at the Veteran's Administration Hospital, Battle Creek, devised 20 affiliation items with face validity. (Items h, 19. N5, and 57 came from a study by Dorris, Levin- son and Hanfmann, Authoritarian personality studied by a new variation of the sentence completion technique, is .9220 29.20 321322.310: 9-2. 1951+. PP. 99-108, and the remaining 16 items were intuitively constructed). The 20 items consisted of 10 pairs, i.e., items of similar content, either in first or third person, 6.3., "I like people who," or, ”He likes peOple who,‘t etc. The items were administered to 23 psychiatric aides at the Veteran's Administration Hospital, Battle Creek, with.instructions to complete the fragments. The data was scored for presence or absence of affiliation imagery by 2 scorers with experience in g;aff scoring (1, Ch. 13). Six of the pairs,5 when scored by the two scorers, re- sulted in significant agreement between the two scorers at the .02 level or better, using the Sign Test for Paired Observations. All of these items also elicited aff imagery in at least 25% of the aide sample. To these six pairs, four pairs of affiliation items with face validity, constructed by the writer, were added, 5 These 12 items are numbers a, 13, 19, 2h, 31, 38, AS, 53, 56, 57, 60 and 61, on the final sentence completion form. 17 yielding the final 20 affiliation items. The serial order of presentation of the affiliation items in the final 60 item.test was based on the following consider- ations: 1) Throughout the 60 items, the first and third person items were in ABBA order. 2) A judgment was made by Melbin and the writer as to what each of the six TAT pictures seemed to depict best, i.e., achieve- ment, power or affiliation situations. The ordering of the sentence completion items was then made to correspond roughly to the ordering of the TAT, accord- ing to the judgment of the writer. For instance, the first TAT picture of the six shows two men working around a machine and was assumed to be a good achieve- ment picture. Therefore, the first sixth of the 60 sentence completion items (10 items) consists of a heavier representation of achievement items (6 achieve- ment, 2 affiliation and 2 power items). The same prin- ciple was followed throughout the remainder of the item ordering. 3) An attempt was also made to keep similar first and third person items apart from.each other in order to minimize copying one to the other. Other Materials- In addition to the Sentence Come pletion Form, the TAT cards and blank for recording tie the responses (see Appendix), each tester received a 18 guide for the interview, which.included introductory remarks and an explanation to the subject of the pur- pose for testing him, instructions for administering the two tests, standardized responses to various ques- tions that might arise during testing sessions, and concluding remarks. A copy of this interviewer's guide also appears in the Appendix. Sample The sample is composed of 100 randomly selected male psychiatric aides employed in the day and evening shifts at the Veteran's Administration Hospital, Battle Creek. (Female aides were not used because there is some evidence that females behave differently on motive measurement than men (10, pp. 172-181). Only one of the aides in the sample refused to be tested and was therefore replaced in the study. The sample was appro- ximately equally divided between Negro and.White aides. Procedure Pro-Study Preparation- Approximately two-thirds of the tests were administered by the writer. The re- mainder of the testing was completed by three psychology trainees and a pharmacist at the hospital. Prior to the actual testing, conferences were conducted with these 19 persons, at which each tester had an Opportunity to interview and administer the TAT to a "practice" sub- ject. Following these practice sessions, discussions as to how the interviewer handled the situations that arose were talked over. It was hoped that these con- ferences would result in a more or less standard ap- proach of the various examiners to the subjects -- a problem which is non-existent in group testing situa- tions. From these conferences and from.the interview- er's guide (see p.19) it was possible to approximate the "relaxed," and "normal," conditions that are re- commended by McClelland (1, p. 36). scenes The TAT protocols were scored by Melbin and the writer. In order to become expert scorers, each of us trained himself with the affiliation manual (1, Ch. 13) and the affiliation practice materials (1, pp. 735-776). In order to compare our proficiency with the criteria recommended by Fold and Smith, (1, Ch. 15), we computed a) percentage agreement between each of us and ex- 6 pert scoring on the presence of motive-related imagery, and b) Pearsonian coefficient of correlation 6 This method is commonly used for reporting scoring re- liabilities for content analysis. The formula is: 2(number of agreements between S and expert on the pre- sence gf_imagery) number of times S scored imagery plus number of times expert scored imagery present. (1 p 238) , O 20 between each of us and expert scoring on the total score assigned each subject. These statistics were computed for Sets F and G, the final sets of practice stories which are used as the criteria of expert scor- ing. (see Appendix). On Set F, Melbin % agreement was .93 and the coefficient of correlation was .97. The writer, on Set F, obtained percentage agreement of .95 and Pearsonian r of .93. On Set G, Melbin's results were .89 and .97, respectively. The writer, on Set G, obtained .9A and .9h. In all cases, these results compare most favorably with.the results reported by Feld and Smith (1, Ch. 15) for research.purposes. The entire scoring of the sentence completion items was done by Melbin. The same conceptual framework and scoring system as applied to the TAT (1, Ch. 13) was utilized for scoring the completions. Hewever, in the case of the sentences, the fragments that were presented to the aides could in some cases themselves be scorable as affiliation imagery. Thus, for a completion to have been scored as containing affiliation imagery, the 93m- pletion itself must have contributed to the sentence's imagery of affiliation. For example, if the fragment, "I like people who,” were completed by, I'eat lobster," affiliation was not scored, whereas it would have been 21 if the completion read, "like me," On this basis, each completion was scored either 1 for presence of aff imagery or 0 for absence of aff imagery. Experimental Design For purposes of statistical analysis, all aides were administered both tests (one half took the sen- tence completion first and the other half took the TAT first) and then randomly divided into two samples of 50 each, hereafter referred to as Sample 1 and Sample 2. The tests were given one after the other in order to measure any one individual at approximately the same time, since, in this case, motivation condi— tions may be assumed to be as nearly the same for both tests than if they were given days apart. (McClelland, (l, p. 33) reports how difficult it is to re-establish the same set in a subject). For Sample 1, the subjects' scores on the sentence Gompletion test were correlated with their scores on the TAT, using the Pearsonian coefficient of correla- tion. It was hypothesized that if the four sentence completion items (of the 20) which elicited aff imagery the fewest number of times be dropped from.the test, and a correlation with the TAT score be recomputed on 22 Sample 1 using the remaining 16 items, the resulting correlation would be higher. The next step was the determination of the maximal multiple correlational weights for the 20 items with the TAT. For Sample 2, the same initial statistical pro- cedure was employed; however, this time, the corre- lation.weights determined from Sample 1 were applied to Sample 2. Once again, it was expected that the 1h item sentence completion would correlate more highly with the TAT than the original 20 item test. Further- more, it was predicted that when the correlation weights from Sample 1 were applied to the 20 items on Sample 2, a higher correlation would be obtained. The final step was to compute the correlation between the 1h item sentence completion test and the TAT for the full sample of 100. 23 RESULTS The major correlations between the TAT test and different forms of the sentence completion test used in this study are presented in Table 1. They range from..ll to .2h. The final correlation for the full sample of 100 with the four least effective items drop- ped, is .23, significant at p.<§05. For Sample 1, 2 and the total sample, it can be seen that the correla- tions between the TAT and all 60 sentence completion items, which includes items designated as achievement and power as well as affiliation, are lower than the correlations using only those items designated as measuring g aff. This may be taken as an indication for the efficacy of those items which were a priori called §.aff items, since they correlate more highly with the TAT measure than do all the items taken tog- ether. Furthermore, as predicted, when the four items which elicited affiliation imagery the fewest number of times were dropped and the remaining items were correlated with the TAT, still higher correlations were obtained. Although these higher correlations 211 TABLE 1 PERSONIAN COEFFICIENTS OF CORRELATION BETWEEN TAT TEST AND THREE FORMS OF THE SENTENCE COMPLETION TEST SAMPLES FORMS OF SENTENCE COMPLETION TEST Aff items minus All 20 n eff L1 lowest All 60 Items items eliciting items Sample 1 N = 50 ell 013 e20 Sample 2 N = 50 .17 .211 .211 Total Sample N ‘ 100 e15 e19 023* * Significant {.05 25 were not in any of the samples significantly higher, they might be interpreted.as indicating a trend toward increasing the correspondence between the two tests. In light of the above results, more items were dropped from the sentence completion test and further correlations were computed with Sample 1. The six lowest glaff imagery items were dropped and this test was correlated with the TAT. The correlation of .21 is not significantly different from the previously re- ported correlations for this sample. Then the 12 low- est 2 eff items were dropped and the correlation was .20. Further low-eliciting item elimination.was dis- continued. In order to check on the possibility of a reverse trend, the four items which elicited the greatest number of affiliation responses were dropped and for Sample 1 the correlation of this test with the TAT was .08 which is low but does not differ significantly from even the highest correlation fer Sample 1, (.20). About halfway through the study, some of the aides complained that this study was being conducted in order to weed out those aides who were not emotionally capable of working in an institutional setting with mental patients. Even though only one aide refused to be tested, it was decided to issue an official memorandum 26 to the effect that these studies were not job-related and results would be held in confidence (See Appendix). Circulation of this memorandum.is likely to have intro- duced another variable which then makes those aides tested before the memorandum and those tested after the memorandum subject to different experimental conditions. Inspection of the test results revealed that the date of issuance of the memorandum could be used as a divi- sion of the 50 subjects in Sample 1 and the 50 in Sample 2 as to the first 25 tested and the last 25 tested in each sample. Using the sentence completion test with the four lowest g aff eliciting items eliminated, correlations with the TAT were computed for the first and last 25 of Sample 1 and 2 and are presented in Table 2. The correlation for the first 25 of Sample 1 was .57. Which is significant at less than the .01 level. (For the latter 25 of the first sample the correlation was .16 which is not highly significant. For Sample 2 the cor- relation was an insignificant .09 for the earlier 25 but for the latter 25 was .112 which is significant at less than the .01 level. Thus, in Sample 2 the trend noted in Sample 1 as far as testing dates is concerned 27 TABLE II PEARSONIAN COEFFICIENTS OF CORRELATION BETWEEN THE SENTENCE COMPLETION TEST (MINUS THE A LONEST n aff ELICITING ITEMS) AND THE TAT FOR THE FIRST AND LAST 25 SUBJECTS IN SAMPLE 1 AND IN SAMPLE 2 Sagle First 25 Last 25 Sample 1 .57* .16 Sample 2 e09 eli-Z‘u' 5 p V ‘ ‘ Ila, .
