Type of Solution in the Problem-Solving Behavior of Normal and Mentally-Retarded Children. Final Report.
Dickerson, Donald J.
Six experiments examined the problem-solving behavior of normal and mentally retarded (MR) children with a two-choice discrimination learning situation: the effects of stimulus similarity upon types of solutions utilized by MR children; the role of redundant cues in the discrimination learning of MR subjects with differing mental ages; the learning of reversal (RV), intradimensional (ID), and extradimensional (ED) shifts by kindergarten children and by MR's as a function of variation of the irrevelant shift dimension; and the hypothesis behavior in the discrimination learning situation of subjects at different developmental levels (data still being collected). Results indicated that stimulus similarity had no effect upon types of solutions adopted by MR children on discrimination problems. For MR subjects form cues predominated over color cues in the solving of discrimination problems, color-form compound cues were used, the negative compound was stronger than the positive compound, and strengths of cues did not change with overtraining. ID shifts were learned faster than ED shifts by MR children under all shift dimensions; ID and RV shifts were learned faster than ED shifts by kindergarten children only when the irrevelant shift dimension varied between trials.
