Abstract:
We developed a new visual search test to assess signs of left visual peripersonal neglect. Five right-hemisphere-damaged patients, 10 healthy controls, and 10 orthopedic controls were administered the test in four conditions: easy task (no distractors)/time-limited (45''), easy task (no distractors)/time-unlimited, difficult task (distractors)/time-limited (45''), difficult task (distractors)/time-unlimited. With respect to controls, most RHDP showed signs of left visual peripersonal neglect in the time-limited condition, but not in the time-unlimited condition, particularly on the difficult task. We suggest that the presence of appropriate time limits, in difficult visual search tasks, could considerably improve the diagnosis of left visual peripersonal neglect.
