The evaluation of auditory-visual speech perception is not typically undertaken in the assessment of aphasia; however, treatment approaches utilise bimodal presentations. Research demonstrates that auditory and visual information are integrated for speech perception. The strongest evidence of this cross-modal integration is the McGurk effect. This indirect measure of integration shows that presentation of conflicting tokens may change perception (e.g. auditory /bi/ + visual /gi/ = /di/). The purpose of this study was to investigate the ability of a person with mild aphasia to identify tokens presented in auditory-only, visual-only and auditory-visual conditions. It was hypothesized that performance would be best in the bimodal condition and that presence of the McGurk effect would demonstrate integration of speech information. Findings did not support the hypotheses. It is suspected that successful integration of AV speech information was limited by a perseverative response pattern. This case study suggests the use of bisensory speech information may be impaired in adults with aphasia.
