A discourse-based approach to semantic feature analysis for the treatment of aphasic word retrieval failures

摘要

Background: Semantic feature analysis (SFA) is a prominent treatment for the word retrieval deficits of aphasia. Generalisation of improved word retrieval on picture naming to discourse production has been an important factor for evaluating the effectiveness of SFA treatment. Unfortunately, generalisation of word retrieval improvements to discourse production following SFA has been modest.
