The influence of age reflected the children's increased experiences with language and increased cognitive develop- ment which stimulated the development of comprehension of the terms tested. Analysis of mean correct responses, by age, indicated the primary set Of relational terms to be--excluding in, on, into, and onto--under, in front of, along side of, and in back of. The secondary set was identified to be under- neath, ahead of, beside, and behind. For the terms in, into, on, and onto, the children responded with the maximum number Of correct responses of three, indicating that by age 2.5 the children in this study had acquired the meaning Of those terms. The terms under and underneath were responded to, also, as similar terms with small differences in mean responses at all age groups except 4.6-4.11. Figure 1 shows the developmental pattern Of compre- hension of the relational terms studied as a function Of age. The pattern, from most complex to least complex, as indicated by mean percentages, was ahead of, beside, along side of, behind, in back of, in front of, underneath, and under. In, into, on, and onto were equally least complex and, therefore, the most easily comprehended. Duncan and Tukey post hoc tests were applied to the means to identify age groups that might differ significantly from all age groups. The results of the post hoc tests showed that there were no groups that differed significantly from all age groups at the 0.05 level.

Eight 2 x 5 analyses Of variance were also performed for the variable Of race (Table 3). The results showed that there was no significant effect Of race on the develop- ment of comprehension of the relational terms studied. As expected, the younger children made more errors than the Older children. An an analysis was made of the types of error that all the children made relative to the reference point Objects used in the study. That is, if the child made an incorrect response in the placement of a toy animal with a reference point Object, what response did the child make? Table 4 shows the types of errors made by reference point object and age group. For example, with the object truck, of the total errors made by age group I, 60% were the relationship in. This meant that when the child did not understand the relational term used or did not understand the relationship indicated, she placed the toy animal in the truck. Table 5 shows the children's patterns of comprehen- sion and production. It shows the percentage of children who comprehended the relational term presented and the percentage of those children who used that term or a socially acceptable equivalent in their productive vocabu- laries. For example, 21% of the children in age group III comprehended the term ahead of and all Of them used that term or a socially acceptable equivalent to express that relationship.

For example, some of the children verbally responded to the relationship in as inside where the terms are somewhat different but the relationship expressed is the same. There were some children who did not comprehend the terms tested or have them in their productive vocabularies, but they did have an understanding of the relationship demonstrated and used an appropriate term to express that relationship. For example, 62% of the children in age group III responded incorrectly to beside in the compre- hension task, but they verbally responded with "by" and "side Of it" when the relationship beside was demonstrated in the production task. Between the ages of 3.5-4.5, most Of the meanings of the terms seemed to develop. The children in this age range, more than others, used other terms to identify the relationships tested as indicated by taped responses. These terms were considered to be socially acceptable words to identify the relationship implied because, though they were different terms, the relationship indicated was the same. For example, for the term along side of, the children frequently Verbalized the words "by", "next to", and "on the side." Those children who neither understood the term pre- sented nor had a socially acceptable word in their vocabu- laries to express the relationship responded with "put it 39 there", "put it like that" and the like to the stimulus "I'm going to put the X and the Y like that. What did I do?" The children in the younger age range, 2.5—3.5, were the ones who most Often gave those kinds Of responses. The children committed very few errors in the production task. That is, if the child did not have a term for the relationship demonstrated, for example cow behind truck, they rarely verbalized an incorrect description Of the relationship. They would not say cow in the truck or cow on the truck. Generally, once the child had an understanding Of the terms tested, she also had a term to express the relation- ship indicated. The terms usually verbalized were those from the primary set. For example, the children in age group V (4.6-4.11) comprehended ahead of but most Often used in front of to express the relationship indicated by ahead of. The data, from the error analysis (Table 4), gave support to E. Clark's (1973) rules for relating Objects with respect to in and on. Rule 1 stated that if the reference point Object was a container the relationship indicated was in. Rule 2 stated that if the reference point object was a flat surface, the relationship indi- cated was on. It appeared that when the children, in this study, did not comprehend the term stated they relied on these rules to make a response. A factor analysis was performed to group the twelve relational terms. A Varimax rotation, the final computation 40 of the factor analysis, appears in Table 6. As suggested by Guttman and adapted by Kaiser,1 all groupings with latent roots of one or more were accepted as factors. Two groupings or factors with latent roots of one or more resulted from the analysis. As pointed out by Child (1975), "'significant' refers to the size a loading must attain before we have confidence that it exists at all and the interpreter of a factor matrix should look for 'conspicuous patterns' formed by the highest correlations." The first grouping portrayed was ahead of, beside, behind, in front of, along side of, and in back of. The terms in Factor I seemed to reflect a laterality or side space dimension. The terms in Factor 2, under and under- neath, seemed to reflect an above/below ground space dimension. With the terms under and underneath, strategies appeared to develop along an above/below ground dimension. That is, the children in this study already comprehended in/into and on/onto establishing above ground. The next progression then was to establish its Opposite or below ground space. Most Of the children, in the youngest age group (2.5-2.11), comprehended under/underneath. For those who did not yet comprehend the terms, according to the factor analysis, the strategy would be to extend perception Of the above ground dimension to establish the below ground 1Child, D., The Essentials of Factor Analysis.

Once below ground is established, the child should begin to comprehend under and underneath. With the remaining six relational terms, strategies appeared to develop along a lateral continuum. That is, the children responded to the dimension of sidedness. With in front of, in the canonical space, an Object "faces" the child. That is, front Space usually contains the characterizing information about the Object. If the placement Of the object showed characterizing features of that Object, the relationship called for was in front of. For example, if that part of the truck with the windows, headlights, and cab faced the child, then that space was in front of. If those characterizing features could not be seen, and cab faced the child, then that space was in front of. If those characterizing features could not be seen, that space was in back of. In back of was also indicated as the space away from the child. The mean correct responses were very similar for these terms; however, in front of appeared to be comprehended before in back of. Along side of corresponded to space between and to the sides of front and back. Here the child had two choices--two sides. With the dimension of laterality, the strategies seemed to generate from establishing the various sides--side with characterizing features and Sides without characterizing features--and sides between them. Clark (1974) hypothesized that nonlinguistic rules last until the child has developed full meanings Of the terms. For this study that appeared to be age 4.6-4.11 43 when the children responded to most Of the terms with maximum correct scores Of three. For the terms in the primary set, the developmental pattern was in front of, in back of, and along side of. The developmental pattern of the secondary set of terms did not mirror that of the primary set. The pattern was behind, beside, and ahead of. The reason for this dif- ference was shown to be that ahead of was the most diffi- cult for all the children and consequently comprehension Of that term was later than for all the others. As shown in the data, the terms in/into, on/onto and--to some extent--under/underneath could be interchanged with no difference in responses from the children. There was, however, a difference in the children's responses to the other terms both in comprehension and production. To further demonstrate the research hypotheses, the response pattern of a typical Black subject in the 3.0-3.5 age range is described. As with the other subjects, she responded with maximum number of correct responses (three) for the terms in, into, on, onto. She also responded with maximum number correct responses for under and underneath. This was consistent with the other subjects in her age group. Her responses to the other relational terms showed emergence of understanding of in front of. She made one correct response to the terms in back of and behind which may have indicated that these terms were beginning to develop. There was no comprehension of the terms ahead of, beside or along side of. 44 In the production task, she verbalized from the pri— mary set for the terms she had an understanding Of. That kind of verbal responding was shown by most of those in her age group and across age groups. Contrary to the others in her group, she demonstrated understanding of the term in front of, but it did not appear in her pro- ductive vocabulary. It is possible that there was a lag between the comprehension of this term and the emergence of that term in her productive vocabulary. A kind Of reverse lag was seen in the comprehension and productive responses Of the next Oldest group. That is, a number of children had no comprehension Of the term ahead of, but in the production task the relationship indicated by that term appeared in the productive vocabulary as in front of. Her response and that of some Of the subjects in the next age group gives some support for Bloom's view (1974) that the relation between comprehension and production is not a static one. This subject's responses were, overall, consistent with her age group and with the rest of the subjects as well as the crisscrossing Of comprehension and production evident in other subjects in her age group and in other age groups. CHAPTER IV SUMMARY AND CONCLUSIONS The focus of this study centered on the development of children's understanding of relational terms. There was also a comparison made of the comprehension of the spatial terms tested and their appearance in the children's productive vocabularies. Age was shown to be the significant factor in the development of the comprehension of the terms in, on, under, ahead of, beside, behind, into, onto, underneath, in front of, along side of, and in back of. The influence of age reflects the children's increasing experiences with language and increasing cognitive development. Race was not shown to be a significant factor. The developmental pattern shown for the comprehension of the terms was under, underneath, in front of, in back of, along side of, behind, beside, and ahead of. In, into, on, and onto were all comprehended by the children at the time this study was conducted. Under and underneath were comprehended by most of the children at the time of testing. These two terms were responded to as the same term with only small dif— ferences in mean scores. The resulting primary set was under, in front of, along side of, and in back of. The 45 46 secondary set was identified as underneath, ahead of, beside, and behind. In the comparison of the production and comprehension tasks, for most of the children, once they understood a given term, they had a corresponding term in their pro— ductive vocabularies to express it. With some terms, most notably ahead of, few of the children had an understanding of that term, but some understood the relationship indi- cated and used in front of to express the relationship. There were instances where comprehension appeared to pre- cede production. For example, some of the children in age group II (3.0—3.5) demonstrated that they understood the terms beside and along side of but had no term to express the relationship. Analysis of the types of errors that the children made gave support for the strategies identified by E. Clark (1973). When the children had no clear understanding of a given spatial term or relationship indicated, they appeared to apply Clark's rules (1973) for placement of the animal Objects with respect to the reference point objects. For example, the children in age group I (2.5— 2.11) did not comprehend ahead of. When a truck was used as a reference point object, the animals were placed in the truck. The rules proposed by Clark were as follows: Rule l--if the reference point object was a container, the relationship called for was in; Rule 2—-if the reference point Object had a horizontal surface, the relationship called for was on if Rule 1 did not apply. 47 Additional strategies were suggested for the other terms studied. With under and underneath, the strategy appeared to be generated from the development Of percep- tion of above/below ground spaces. In, into, on, and onto served to establish above ground (positive end) and the extension (negative end) from that would be below ground. With ahead of, beside, behind, in front of, along side of, and in back of, the strategy appeared to be generated from the development Of perception of lateral or side spaces. For example, in front of was the space containing the characterizing information pertaining to a particular Object. Implications for Therapy_ It is important that diagnosticians and clinicians have information as to how children normally respond in order to have some basis for comparison with those children who have delayed or disordered development of language. As stated previously, relational terms are used frequently in diagnostics and therapy. From the research, it has been shown that as a function of age--related to increased language experience and cognitive development--there was a developmental pattern to the terms studied. While this was less evident for the Older children, it was very evident for the younger children and did persist across age levels to some degree. The younger children made very differentiated responses to the primary and secondary sets of terms. Again, the Older children responded to the terms 48 in a similar manner though the terms in the primary set were responded to overall more correctly. With respect to comprehension and production, it was shown that the relationship between them was not a simple one, nor was it a one to one relationship. For some of the terms, comprehension seemed to precede production and for others the reverse appeared to be true. Children showed preferences in the production task and used the terms (primary set) that were more common everyday terms. These are probably also the terms that parents and Others in the child's environment first use to specify relation- ships for the child. Brown (1958) discussed the behavior of parents in selecting the simplest words when talking to children. In diagnostics and therapy, the least com- plex terms would best be used; for example, in back of rather than behind. If relational terms are being taught, teaching first in a framework of perceptual awareness, beginning with the least complex terms and building to the more complex terms would, in all probability, result in some measure of success. As indicated by the factor analysis, there were two common threads that ran through a number of the terms and revealed two factor groupings. A number of these terms are used in language assessment and therapy. In this study, the dimensions of laterality and above/below ground space were shown in the terms. In therapy, then, it might be necessary to build awareness of these dimensions if teaching these terms and possibly others that are similar. The developmental pattern shown 49 by the children's responses also gives indications Of what terms might be selected for therapy--which terms seem to be important as dictated by the order that the child learns them. Questions Related_to Perceptugdly_ BESed Strategies Questions have been raised relating to the validity Of the concept of perceptually based strategies in language acquisition (Menyuk, 1973). To answer some Of the questions, one of the primary factors generated from this study was the developmental pattern Of the terms studied. The develop- ment was consistent over the various ages--that is, as the children were Older in age, they comprehended more of the terms. This, as stated previously, is related to the children's increasing cognitive development and increasing experiences with language. There was also consistent responding in the production task where the terms in the primary set were the ones verbalized most Often by the children. Additional support came from the factor analysis, which highlighted the two perceptual dimensions that related the terms together in groups--one based on above/below ground space and the other based on lateral space dimension. Implicationshfor Future Reggarch The purpose of this study was to investigate the development of understanding of relational terms in children. Additionally, it was to compare their comprehension and production voCabularies as these pertained to the 50 acquisition of the meanings of the spatial terms studied. The data suggested that there was a developmental pattern in the acquisition of meaning of these terms and that a primary set (more easily understood set) and secondary set (less well understood set) of terms could be identi- fied. A question is raised as to whether this pattern would hold true for other spatial terms and other types of relational terms such as adverbs. All of the children in this study were native speakers of English with no other language contact. It is possible, then, that children from a bilingual background would acquire mean- ings of spatial terms in a different developmental pattern as influenced by possible perceptual organization dif— ferences. The children, too, were all in pre-school programs where they are encouraged to be verbal and are given many opportunities to talk and to listen, not only to peers but to adults as well. It could be expected, then, that the levels and types of responses given were influenced by the verbal behavior shown in the pre-school settings. It is possible that children who are not in pre-school programs would show differences, perhaps in rate of acquisition of meanings according to age. The birth order data were not analyzed because of unequal sample sizes within age groups; however, birth order has been suggested as a possible influence in overall development as well as language development (Nelson, 1973). This, also, is an area that might be studied further as it 51 pertains to the development of comprehension of relational terms. A final area of suggested research is the area of experimenter influence. Rosenthal's (1966) research indicated that experimenter bias might influence the responses of the subjects. According to Williams' (1970) research, with Black children, the interviewer's expec— tations of the child is one of nonstandardness, reticence and uncertainty. The child's expectations of the inter— viewer is one of dominance, confidence, and verbosity. It is not unusual that so often they have fulfilled their joint prophecies. With same race researcher, Gillum (1976) reported that there was no difference in the Black children's ability to make judgments of grammati- cality from the White children though the experimenter was Black. There did not appear to be an unusual influence of the Black experimenter, in this study, on the responses of the Black children. This is, however, an additional area to be studied more thoroughly relative to same race examiner and the influence that there might be on the children's responses.
