PROBLEMWith the exception of Fischer(2* a ) and DeMartino(I), analyses of figure drawing size and sex identification components related to the mentally retarded have been quite meager. This study investigated the relationship between the height of drawings obtained from a sample of mental retardates and IQ, sex and CA, as well as the extent of sexual ambivalence suggested by the first drawn figure.
METHODThe Ss were 129 residents of a state residential center for the mentally retarded. There were 73 males and 56 females ranging in age from 13-0 to 20-0. All Ss were administered the human figure drawing projective technique in small groups in the school area. They were asked to "draw a person" on an 8% x 11 inch sheet of white paper; all were given the same instructions under the same conditions. Sex of the fist figure drawn was ascertained by individual questioning. Intelligence quotients were derived from either the Wechsler or Stanford-Binet Scales.
RESULTSThe IQ's of the 129 Ss ranged from 35 through 80. The mean I& for the total group was 57.9, females 57.4 and males 58.3. The total sample was divided into sub-groups on the basis of I& as follows: 35-50 (N = 38)) 51-65 (N = 59) and 66-80 (N = 32). The mean height of the drawings in millimeters of the fist group was 150.09 mm, of the second group 121.28 mm, and of the third group 115.06 mm.To determine whether a relationship existed between the height of figure drawings and intelligence levels, an F test was run as a test of significance. The null hypothesis of no difference was rejected at the .05 level of significance. Thus, as intelligence increases there is a proportionate decrease in the height of drawings.A t test was run to determine significance between the 35-50 and 51-65 I& groups, and the null hypothesis was rejected at the .001 level. A t test between the 51-65 and 66-80 I& groups was also conducted, resulting in no significant difference between the heights of figures for these I& groups. As intellectual functioning enters the mild ranges of mental retardation and above, there is a proportionate decrease in the height of drawings, suggesting in turn an increase in constriction, ego deflation and internal orientation.The percentages of those who drew the opposite sex first, 41% of the females and 26% of the males, are higher than generally found in studies utilizing so-called normal Ss though approximately the same for mental retardates as reported by Fisher@. 8 ) .The t test was applied to determine the significance of the difference in the height of drawings between males and females. The mean height of the female drawings was 126.77 nim, SD 55.14; that of the males 130.58 mm, SD 65.11. The difference was not significant.The relationship between chronological age and height of drawings waa analyzed by first establishing three subgroups as folIows: 13 to 15-4 (N = 51), 15-4 to 17-8 (N = 50) and 17-8 to 20-0 (N = 28). Using 131.92 mm, 126.30 mm and 128.50 mm as the means for the groups respectively, the F test revealed no statistical significance; ...
