Individuals with developmental disabilities demonstrate deficits in intellectual and adaptive functioning that can include difficulty describing past events; accurate recall may be improved by learning to engage in precurrent, or problem solving, behavior. Visual imagining is a problem-solving strategy that involves seeing in the absence of the stimulus that was once seen. In the current study, a systematic training model using visual imagining in addition to prompting and reinforcement was evaluated with seven young men ages 12 to 19 with an autism spectrum disorder. Following training, an increase in independent and accurate tacting of stimuli from previously-seen images was observed with all participants at short delays and delays up to 2.5 hrs.
