ABSTRACT

The use of touchscreen devices for communication purposes has been shown to be effective in the literature; however, there is little research in the effectiveness of applying naturalistic teaching approaches in developing discriminative requesting in young children with autism spectrum disorder (ASD). Two participants between the ages of 3 and 5, who were non-vocal, were taught to select a target symbol when presented with varying number of non-target symbols. Behavioral therapists who frequently interacted with the participants were trained to implement the intervention during playtime within their natural environment. We used a multiple probe design across different field sizes to eval uate the effects of the intervention. Results revealed that the symbol discrimination training and naturalistic teaching methods yielded high-to-medium effects on the acquisition of discriminative requesting and the generalization of such skills across novel stimuli.
