Attention & Inattention

One of the most profound disorders of attention is the syndrome of unilateral neglect. This is a common and disabling condition which is observed most frequently in patients with stroke. Neglect is far more severe and more frequent in people who have suffered a right-hemisphere stroke, occurring in upto two thirds of such individuals acutely.

Such patients fail to explore items to their left, often unaware of objects or people to that side. If we track their eye movements while they perform a visual search task (e.g. trying to find the letter T embedded among rotated Ls) we can observe just how restricted their leftward exploration of space is. Here the red dots represent gaze fixations and the yellow lines show paths taken by the eyes.
