Sixty-five children, who were predominantly of Mexican origin, were tested in Spanish. Since the equivalence of the Spanish and English versions of the PPVT was not determined, data from children tested in Spanish were analyzed separately from data of children tested in English. Draw-A-Person (Machover, 1948) rather than Draw-A-Man instructions were used for the figuredrawing test. Data on sexual identification will be reported in a later paper. Bliss and Berger (19S4) have concluded that the two forms of the test yield substantially the same results. Unless the drawing was identified as a woman by the child, ambiguous figures were scored by the Goodenough-Harris criteria for drawings of men (Harris, 1963). Of the 956 drawings, 239 were not recognizable figures (Class A), 111 were scored by Draw-A-Woman criteria, and 606 were scored by Draw-A-Man criteria. Interrater reliabilities among the four scorers ranged .S9-.99 for samples of 14-50 drawings. (For a detailed report of sampling, selection, and testing procedures, see Commins, Cort, Henderson, & O'Keefe, 1967.) RESULTS AND DISCUSSION Mean Standard Scores The DAP and PPVT raw scores were converted to standard scores; the mean standard score at each age is set at 100 for the normative samples for both tests. Table 1 shows that regardless of age, sex, or ethnic group, the average performance on both the DAP (overall mean standard score, 77.22) and the PPVT (overall mean standard score, 82.02) was substantially lower than the mean for the normative samples. The low PPVT standard scores are consistent with the poor performance on verbal tasks frequently reported for children from lower class and minority group families (Deutsch, 196S). The low DAP standard scores were to some extent unexpected. Previous studies have indicated that at least four relatively disadvantaged groups have achieved mean standard scores of about 100 on the DAP. Such means were reported for white and Negro kindergarten children in New York City public schools (Vane & Kessler, 1964), for white and Negro S-year-old children in a New York City day care center (Anastasi & D'Angelo, 1952), and for a representative sample of 300 Negro firstgrade children from southeastern states (Kennedy & Lindner, 1964). Bowers and Giles (1966) found an increase in DAP scores as socioeconomic status increased among 6- to 12-year-old children in Evanston, Illinois, but the mean DAP standard scores for the lowest socioeconomic groups, regardless of sex or age, were about 100. The norms for younger children on the DAP are not geographically and economically representative of the national population at TABLE 1 DAP, PPVT, AND PSI CORRELATIONS BY SEX, ETHNIC GROUP, AND AGE IN A SAMPLE OF 956 PRESCHOOL CHILDREN ENROLLED IN PROJECT HEAD START Group Total Sex, ethnic groupb Boys, white Boys, Negro Girls, white Girls, Negro Spanish-speaking Age* 3 4 5 6 N 956 188 273 166 264 65 n 397 335 87 M age0 60.3 63.3 56.4 62.1 58.2 71.8 44.1 54.9 63.8 76.0 M standard score PPVT 82.02 89.26 80.64 85.18 79.32 69.77 80.01 82.23 84.32 83.02 DAP 77.22 76.57 76.02 78.14 77.45 80.66 76.76 78.76 74.21 79.53 Raw-score correlation DAP/ PPVT .46 .40 .52 .51 .44 .53 .38 .22 .31 .52 DAP/ PSI .56 .51 .56 .60 .54 .60 .39 .26 .44 .57 PPVT/ PSI .73 .69 .72 .77 .65 .72 .48 .69 .62 .80 * In months. >> Includes only children tested.in English; too few children were tested in Spanish to compute data for sex and age subgroups
