Exogenous and endogenous shifts of attention in perihand space

摘要: While some studies have found that attentional orienting is altered in perihand space, most not. One reason for such discrepancies may be related to the types of cues (uninformative and informative) been used, as they are known induce different shifts attention (exogenous endogenous, respectively). To systematically address this question, two experiments were performed which an uninformative peripheral cue (Experiment 1) or informative central 2) preceded a target with short (100–150 ms) stimulus-onset asynchrony. Participants task their left hand, right both hands, no hands near display. Cueing effects obtained experiments, but only modulated by hand position Experiment 1, larger observed right- both-hand conditions. These findings suggest exogenous affected proximity, while endogenous
