Abstract
When a leading cue stimulus is presented near a subsequent target, the perceived location of the target is displaced from the cue (attentional repulsion). On the other hand, a target is sometimes mislocalized toward the cue (attentional attraction) or fovea (foveal bias). In the present study, we assumed that these three mislocalizations were the individual spatial distortion depending on a retention interval after seeing the target, and then we sought how the order of these mislocalizations was. We used a relative location judgment task and manipulated the stimulus-onset asynchrony (SOA) between the target and the probe across three lengths (0, 550, and 1250msec). The results of Experiment 1 showed that attentional repulsion occurred with SOA of 0ms, and next, foveal bias occurred with SOA of 550ms, and finally, attentional attraction occurred with SOA of 1250ms. Moreover, Experiment 2 demonstrated that attentional attraction occurred without prior attentional repulsion. These results suggest that attentional repulsion occurred at the perceptual stage and location information of the target is exposed to dual distortion of foveal bias and attentional attraction at the memory stage.
