Description

<p>The present study investigated effects of interventions in which the participant was instructed to make gestures corresponding to vocal or visual stimuli, and mechanisms of acquiring receptive language through the mediation of gestures. The participant in the study was a boy (age 4 years 2 months at the start of the study) who had been diagnosed with autism spectrum disorder, and who had diffıculty acquiring receptive language relating to the names of things. He was given matching-to-sample tasks in which he was instructed to choose picture cards that corresponded to vocal stimuli. The following instructions were introduced successively: (a) make gestures corresponding to vocal stimuli, and (b) make gestures corresponding to visual stimuli (picture cards) presented together with vocal stimuli. He was given stimulus equivalence tests before and after the interventions. The results indicated that his acquisition of receptive language was facilitated better when he was instructed to make gestures corresponding to picture cards accompanied by vocal stimuli, compared to when only vocal stimuli were presented. Moreover, there were stimulus relationships among the 3 types of stimuli (vocal, gestural, and visual) after the interventions. The mediation of gestures appeared to be effective for his acquisition of receptive language. These fındings suggest that instructing the boy to choose a picture card corresponding to a vocal stimulus and make a gesture might have functioned as a joint control of his behavior.</p>
