Imposed delay of response: effects on aphasics auditory comprehension of visuality and non-visually cued material

Two groups of aphasics were administered an auditory comprehension task under conditions of 0-, 5-, and 10-sec. imposed delay of response. The auditory-visual group received auditory and visual cues; the auditory group received only auditory cues. Comprehension for the auditory-visual group was significantly better than for the auditory group. Increase in delay time significantly improved comprehension for the auditory-visual group but not for the auditory group.
