An operant procedure for improving vocabulary definition performances in developmentally delayed children. 1980

A W Cottrell, and J Montague, and J Farb, and J M Throne

This report describes a training program in which operant procedures were used to improve the identification and definition of selected vocabulary words in three developmentally delayed children. Generalization from the training words was well established, as determined by responses to untrained vocabulary performance words. The results of this procedure suggest its application with other developmentally delayed children.
