Abstract

This single subject, multiple baseline intervention compared implicit and explicit treatments to improve verb retrieval. This implicit intervention is based on theoretical models of lexical retrieval that propose that spreading activation of close semantic neighbors is essential for the preparation of lexical items for production. Results were analyzed and revealed an increased number of correct responses following explicit treatment. Implicit treatment decreased the number of response failures and increased the number of semantically related errors suggesting that implicit treatment may have helped the participant overcome reluctance to respond. Results warrant consideration of implicit treatment as an adjunct to standard therapy.
