Jewish culture and psychological differentiation--partial replication

A replication study was made to test the following hypotheses: (a) Traditional-Jewish Ss, in comparison with Anglo-Saxon Protestant Ss, matched for age and verbal ability, will be more global on criterion measures of psychological differentiation. (b) Within group intercorrelations of these measures will all be in the positive direction. Ten pairs of boys (ages 9-11) were compared on the Embedded Figures, Human Figure Drawing, and Verbal Disembedding tests. The first hypothesis was confirmed with regard to Embedded Figures (p less than .05), but not with regard to the other two criterion measures. The within group intercorrelations were r = .25 to .48 for Embedded Figures versus the other two measures. The correlations between Verbal Disembedding and Human Figure Drawing were small and negative (all correlations were nonsignificant).
