The importance of time limits in detecting signs of left visual peripersonal neglect: a multiple single-case, pilot study.

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.
