Developmental Visual Neglect in Infants

Infants from 16 to 20 weeks were presented with objects moving across a spatial field of 60cm. Visual tracking increased between 16 and 18 weeks, reaching increased, while arm lifts (swipes) showed no age change. A neglect of the left visual field in tracking gradually disappeared with the onset of reaching. Similar effects of arm movements towards the neglected side can be found in the successful treatment of adult visual neglect patients. Besides the neurological background, results are evaluated from developmental and comparative perspectives.
