This study demonstrates that operant conditioning effectively reduces echolalia in handicapped children. The technique, involving reinforcement and punishment, led to appropriate question responses and sustained improvements over time.

Area of Science:

Behavioral Psychology
Developmental Psychology
Speech-Language Pathology

Background:

Echolalia, the repetition of speech, is a common characteristic in children with developmental disabilities.
Effective interventions are needed to improve communication skills and reduce repetitive speech patterns.

Purpose of the Study:

To investigate the efficacy of an operant-conditioning technique in reducing echolalia and improving question-response skills in handicapped children.
To assess the generalization and maintenance of trained responses.

Main Methods:

An operant-conditioning procedure was employed with three children exhibiting echolalia.
The technique involved punishment for echolalic responses and reinforcement for appropriate, cued responses.
A within-subject multiple baseline design was utilized to track progress.

Main Results:

Significant increases in correct question responses were observed for all participants.
Echolalic responding was eliminated for trained questions.
Generalization of trained responses to untrained questions and settings was noted, with sustained improvements at 12-month follow-up.

Conclusions:

Operant conditioning is a viable and effective method for reducing echolalia in handicapped children.
The intervention promotes functional communication, generalization, and long-term maintenance of learned behaviors.
