Abstract

Children with neurodevelopmental disorders may experience difficulties in language development. The use of visual supports in speech instruction can serve as tools to aid in information processing. This study aimed to evaluate whether a set of visual and auditory stimuli could support children with autism in initiating vocal mands. Two children with a generalized echoic repertoire were invited to participate in the study. The procedure included a baseline phase, in which the children’s mand repertoire was assessed, and an intervention phase, which involved the implementation of a teaching procedure using visual prompts and echoic cues to teach manding through phrases. A prompt hierarchy was used. The results showed that both participants demonstrated an increase in the percentage of vocal mand emissions following the intervention.
