Contingency management in the classroom treatment of long-term elective mutism: A case report

An 11-year-old boy with a six-year history of elective mutism in school was successfully treated with operant reinforcement and contingency management techniques. The plan was carried out by the classroom teacher with a minimum amount of management consultation. Twelve-month follow-up reveals continued maintenance of the verbal interaction indistinguishable from that of other children at school which was set as the criterion for terminating the intervention. The plan was carried out in three stages-relationship-building to develop teacher-pupil interaction into a reinforcing event, audible-response eliciting, and generalization throughout the school building and grounds.
