The report by A. Stephens and J. McLaughlin (1974) on retarded-nonretarded group differences in performance on Piagetian reasoning tasks was critically examined. (Author)

Studies of thioridazine (Mellaril) use for treating childhood behavior disorders (psychosis, hyperactivity, behavior problems, emotional disturbances) were reviewed with a special emphasis on methodology. It was found that the caliber of these studies has been unsatisfactory and that measures of drug effect have tended to stress global rather than…

Twenty-eight educable mentally retarded (EM R) children participated in an 8-week training program on choosing the best alternative. (Author)

The performance of 4 groups of mentally retarded Ss, ages 14-17 with mental ages of 8-11, was compared to that of 90 non retarded Ss, grades K-5 with comparable mental ages, on the solution of 2 and 3 disc Hanoi Tower puzzles, solutions to which require logical forsight. (BB)

Measures from a laboratory task and a free play observation suggested that attention is a key factor in understanding the high risk child's development and also that differences in attention between high and low risk children can be reliably obtained as early as three years of age. (Author)

The relationship between performance on a Piaget-based infant scale and adaptive behavior was assessed for 25 developmentally disabled infants and preschool children. (Author)

Two experiments were conducted to explore the feasibility of training 42 and 72 mildly retarded adolescents to solve class-inclusion problems. (Author)

Intelligence levels of a sample of 180 Down's syndrome children were reported, and the results indicated that their abilities are not as limited as previously thought. (Author)

Thirteen retarded adults at each of three mental age levels (5 to 6, 7 to 8, 9 to 12) were assessed on classification, relativity, and transitivity performance. (Author)

Investigated were J. Piaget's ideas of the sensory motor stage of intelligence by determining whether six developmentally delayed children (aged 21 to 31 months) could use two different strategies appropriately to look for two different tokens. (Author/DB)
