Echolalia is the repetition of utterances produced by others. There are two types of echolalia—immediate and delayed.
Historically, echolalia has been described as meaningless and without communicative function. However, a growing body of research has identified various communicative functions of echolalia (e.g., turn-taking, labeling, requesting, affirming, and protesting) and has suggested its role in gestalt language acquisition (Prizant, 1982, 1983; Prizant & Duchan, 1981; Prizant & Rydell, 1984; Stiegler, 2015).
Gestalt language acquisitionis a style of language development with predictable stages that begins with production of multi-word “gestalt forms” and ends with production of novel utterances.
This view of gestalt language acquisition and the role of echolalia in individuals with ASD is reflected in assessment procedures (e.g., assessing communicative function of echolalia) and treatment approaches to language intervention (see e.g., Blanc, 2012).
For a discussion of gestalt language acquisition in typically developing children and in children with ASD, see Prizant (1983) and Stiegler (2015).
