Orienting to extinguished signals in hemispatial neglect

This study tested for spatial orienting effects, without awareness, to sign als presented in the neglected hemifield of 2 hemispatial-neglect patients. The experiment adapted a spatial precuing paradigm for measuring the effec ts of visual attention. Contralesional orienting hastened subsequent target detection at the location of an extinguished precue. These findings valida te a claim that orienting can occur independently of overt detection and in dicate that location information is registered in the neglected field.
