Extinction can occur in auditory and visual modalities.
The primary focus of this project is to determine what difficulties exist with attention after stroke and to eventually develop intervention for speech pathologists in order to help this population. Project will begin in April or May and will tentatively continue through the summer of 2001. If further support is found, research will continue until 2005. Individuals who have suffered a right hemisphere stroke may have deficits in attention. Research has shown that the attentional phenomenon of extinction occurs in the auditory, visual, and tactile modalities in these individuals.
