Abstract

Studies of endogenous and exogenous attentional orienting in spatial cueing paradigms have been used to investigateinhibition of return, a behavioral phenomenon characterized by delayed reaction time in response torecently attended locations. When eye movements are suppressed, attention is covertly oriented to central orperipheral stimuli. Overt orienting, on the other hand, requires explicit eye movements to the stimuli. Thepresent study examined the time course of slowed reaction times to previously attended locations when distractorsare introduced into overt and covert orienting tasks. In a series of experiments, manual responses wererequired to targets following central and peripheral cues at three different cue-target intervals, with and withoutactivated oculomotor systems. The results demonstrate that, when eye movements are suppressed, behavioralinhibition is reduced or delayed in magnitude by the presence of a distractor relative to conditions withoutdistractors. However, the time course of behavioral inhibition when eye movements are required remains similarwith or without distractors.
