Common neuropsychological deficits associated with stroke survivors' impaired performance on a useful field of view test.
Useful field of view is a measure of information processing in peripheral vision that has potential for predicting impaired driving performance. The present study was performed to examine whether common neuropsychological deficits resulting from stroke might be associated with useful field of view impairment. 46 stroke survivors had impaired useful field of view test performance when compared to individuals without stroke (t30.6= -4.33, p<.001). The impairments in useful field of view of stroke survivors were associated with impaired peripheral fields, slowed processing speeds, and diminished attention. Such impairment was not localized to lesions in any particular brain area. Results allow the inference that common neuropsychological impairments may have contributed to inefficient extraction of visual information from peripheral vision.
