Assessment and Treatment of Prosody Behavior in Individuals with Level 1 Autism: A Review and Call for Research.

Differences in prosody behavior between individuals with autism spectrum disorder (ASD) and their typically developing peers have been considered a central feature of ASD since the earliest clinical descriptions of the disorder (e.g., Kanner, 1943/1973). Prosody includes pitch and volume among other dimensions of vocal-verbal behavior that discriminate responses of the listener; thus, people with ASD whose prosody has confusing or off-putting effects may have fewer social opportunities at work, at school, or in the community. The purpose of this review is to examine the state of the literature intervening on prosody with individuals with ASD and to provide recommendations for researchers who are interested in contributing to the scientific understanding of prosody. © Association for Behavior Analysis International 2021.
