A Comparative Study of the Intelligence of Jewish Preschool Boys and Girls of Orthodox Parentage

Children aged 2-51/2 to 5-1/2 were pretrained on two three-choice simple discrimination problems presented consecutively, which were followed by training on 10 unique oddity sets. Transfer data were obtained from those Ss who learned the oddity problems by presenting five new oddity sets.

All three Groups learned the second pretraining problem more quickly than the first, although on both problems the two older Groups learned faster than the youngest Group. Nearly all the Ss learned to select the correct stimuli on the 10 three-choice oddity sets. Sixty-four percent of the children between 2-1/2 and 4-1/2 evidenced transfer to the five new oddity sets, indicating comprehension of the oddity relationship and the ability to respond on the basis of this higher-order solution. This finding is contrary to that predicted by contemporary theories of cognitive development (e.g., 3, 8).

The remaining Ss had either learned to choose the odd stimulus, but were unable to maintain a relational choice when presented with new sets, or solved the original discrimination by applying specific solutions to a 10-problem simultaneous three-choice discrimination problem.
