The purpose of this article is to discuss a cognitive approach to therapy with a language impaired adult. Two types of productive thinking are explored in this research: concept awareness and problem solving. These are dynamic and creative processes underlying the development and use of cognition and language. This single subject study follows an ABAB design and describes techniques used in therapy and methods for measuring productive thinking in a 66-yr-old moderately language impaired adult. Results indicate a sharp increase in the subject's thought productivity in a variety of contexts. A critical appraisal of reasons for therapy effectiveness are given. |
