Effects of two cueing treatments on lexical retrieval in aphasic speakers with different levels of deficit

The effects of two cueing treatments for lexical retrieval were examined wi th three aphasic speakers who demonstrated different levels of lexical proc essing impairment (i.e., predominately semantic, predominately phonologic, and mixed semantic-phonologic). Each speaker received both treatments, with treatments being applied sequentially to different word lists in a multipl e baseline design. Both treatments consisted of a prestimulation phase foll owed by the application of a response-contingent cueing hierarchy. One trea tment employed semantic-level cueing, whereas the other treatment utilised phonologic-level cueing. All participants evidenced a positive response to both of the treatments and one participant (predominately phonologic-level deficit) showed a superior response to lexical-semantic treatment.
