An analysis of changes in CA, MA, and IQ in 324 patients, representative of the population of a hospital for mentally retarded, indicated that the decrement in IQ in mentally retarded children is due primarily to increases in CA and not to decreases in MA.

Ratings of pattern goodness and of pattern preference were made by 96 subjects for each of 50 stimulus patterns of known pattern uncertainty. Equal numbers of male and female subjects were used in each of four age groups (9-10), (13-14), (5817-18), (20-21). Pattern preference was similar for all age groups, with the least uncertain patterns…

They may, in fact, depending upon group-care philosophy and practice, as well as reasons for admission, surpass their home-reared counterparts in psychological…
