Discrimination of Bidimensional Stimuli by Autistic Children

Four autistic and four normal children were trained to respond on a series of four bidimensional complex-component discrimination tasks where the complex stimuli were comprised of auditory and visual components. The results indicated a transfer of learning effect for the autistic group. The increment in performance was such that the autistic group’s performance did not significantly differ from the normal group on the last task. These results were seen as encouraging evidence that the apparent phenomenon of stimulus overselectivity, as described in previous research, is not an enduring characteristic of autistic children. It was suggested that further research is needed to establish the appropriate training methods to enable these children to respond to environmental demands in a more adaptive manner
