The Feasibility of Training Mental Retardates to Use Available Channel Capacity More Economically. Final Report.
Jones, Elvis C.
A pilot study and two formal studies were conducted with educable mentally handicapped (EMR) children to develop materials and procedures suitable for studying schema learning in EMRs and to demonstrate schema learning in EMRs in the absence of external guidance. The pilot and formal study I were conducted to develop suitable populations of stimuli conducive to minimal performance, allowing improvement room without arousing frustration. The Ss reproduced checkerboard patterns having 16, 20, 25, 30, and 36 cells, respectively. It was found that Ss performed above chance on matrices with 36 cells, cell number retained by Ss was not significantly affected by total number of cells within patterns, and visual channel capacity might be related to verbal components of intelligence. Formal study II was conducted to determine if EMRs were capable of schema concept learning using stimuli patterns from both pilot and first formal study. One group reproduced schema patterned checkerboards, while another group reproduced nonschematic patterns. Results indicated that EMRs were capable of schema concept learning without either prototype exposure or external feedback. (CB)
