Multimodal temporal perception deficits in a patient with left spatial neglect.

We examined multisecond time estimation (up to 60 s) for visual and auditory events in a patient with left spatial neglect (RR), who grossly underestimated all durations in all tasks. In contrast, healthy controls and a patient with left hemisphere damage (HW) demonstrated accurate estimates of the same durations. These findings add to a growing body of literature suggesting that neglect cannot be understood simply in terms of a bias in orienting attention to one side of space. In addition, these data suggest that the right hemisphere parietal cortex may be important for the perception of time across multiple modalities.
