The mapping hypothesis and aphasia therapy

This paper reviews the contribution made to aphasia therapy by the mapping hypothesis. The introduction describes the development of the hypothesis and considers its implications for therapy. A review of mapping therapy studies follows. It is argued that although mapping treatments have produced encouraging results which are broadly explicable within the hypothesis, the details of outcome and differences between the patients are very difficult to interpret psycholinguistically. The concluding discussion considers some of the unresolved questions and offers suggestions for future research developments.
