Action-concept usage by nonretarded and retarded children on structured tasks with praise for performance.

In equivalence-formation tasks, retarded children have been ovserved to use fewer action concepts than expected on the basis of their MA. When tasks were structured and praise for performance was introduced, mildly retarded children performed like nonretarded children in most respects, except for total number of responses. Moderately retarded children of the same MA showed improved performance but still performed more poorly than either of the other two groups. The implications of these findings were discussed.

Action-concept learning in retarded children using photographic slides, motion pictures, sequences, and live demonstrations.

The inadequate use of action concepts by mentally retarded children has been reported in several recent studies, but little is yet known concerning the level of performance that might be expected to result from direct instruction designed to remedy this deficit. In the present study, it was found that three different instructional approaches yielded higher adjusted posttest scores. The highest adjusted posttest score was yielded by an instructional program in which motion picture sequences were used. This program was significantly more effective than two paralled programs, one using photographic slides, and the other using live demonstration by a teacher. An explanation for these findings was suggested.
