Comparing phonological and orthographic cues in the treatment of word retrieval disorders in aphasia

This paper examines the effects of phonological and orthographic cues on spoken naming in aphasia. The aim of the study was to determine the relationship between the effects of phonological and orthographic cues and the underlying functional language impairment and to identify the mechanisms by which the cues have their effects within a neurolinguistic word-processing model (Patterson & Shewell, 1987). We present the results from six anomic participants with chronic aphasia using a case-series design. Both effects of a single application and of multiple applications of cues were assessed, as were both immediate and delayed effects.
