Article: On the Uniqueness of Attentional Capture by Uninformative Gaze Cues: Facilitation Interacts With the Simon Effect and is Rarely Followed by IOR

Abstract

Orienting to an uninformative peripheral cue is characterized by a brief facilitation followed by a long-lasting inhibition once attention is removed from the cued location. Although central gaze cues cause reflexive orienting, the inhibitory effect that is relatively ubiquitous following exogenous orienting to uninformative peripheral cues has been relatively rare. We hypothesized that IOR might be seen following gaze-induced orienting if attention were effectively returned to centre by a return gaze or return flash. The time-course of gaze-directed orienting was measured by varying the interval between the gaze cue and a peripheral target requiring an orientation discrimination ...
