  • Title: The effects of two levels of linguistic constraint on echolalia and generative language production in children with autism.
    Author: Rydell PJ, Mirenda P.
    Journal: J Autism Dev Disord; 1991 Jun; 21(2):131-57. PubMed ID: 1864826.
    Abstract:
    The effects of specific types of adult antecedent utterances (high vs. low constraint) on the verbal behaviors produced by three subjects with autism were examined. Adult utterance types were differentiated in terms of the amount of control the adults exhibited in their verbal interactions with the subjects during a free play setting. Videotaped interactions were analyzed and coded according to a predetermined categorical system. The results of this investigation suggest that the level of linguistic constraint exerted on the child interactants during naturalistic play sessions affected their communicative output. The overall findings suggest that (a) adult high constraint utterances elicited more verbal utterances in general, as well as a majority of the subjects' echolalia; (b) adult low constraint utterances elicited more subject high constraint utterances; and (c) the degree of constraint of adult utterances did not appear to influence the mean lengths of subjects' utterances. The results are discussed in terms of their implications for educational interventions, and suggestions are made for future research concerning the dynamics of echolalia in interactive contexts.
