Performances of 18 retarded young adults on the Porteus Maze Test (a measure of planning capacity and foresight) were compared with those of 117 first- through fourth-grade nonretarded children. (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)

Results suggested that, when encountering difficulties in the problem-solving situations on the test, the retarded Ss tended to take the easiest or shortest path to a response by scanning a minimum amount of material. (Author/DLS)

Twenty-two educable mentally retarded (EMR) adolescents and 19 nonretarded children of equal MA were given the preschool and elementary forms of the Matching Familiar Figures Test to assess reflection-impulsivity. (Author)

Thirty-four educable mentally retarded young adults were given a one-bit logic problem (Experiment 1) or a test of conservation (Experiment 2) and classified as either low or high performers. In a second session, the low performers were paired with the high performers, and the dyads were required to agree on the solution to the problems presented.…

Available from: Ablex Publishing Corporation, 355 Chestnut Street, Norwood, New Jersey 07648. Two groups (36 Ss) of educable and trainable mentally retarded adolescents in an institution were compared with two groups (38 Ss) of nonretarded children (ages 8-9 years old) on a modified tic-tac-toe game for foresight in logical problem solving.
