Abstract
This study examined whether a briefly presented target was mislocalized toward a subjective contour. Observers manually reproduced the position of a briefly presented peripheral target circle above a central fixation cross. A luminance contour, a subjective contour, or a no-contour stimulus was presented in either the left of right visual field, and a no-contour control was presented in the opposite visual field. After these stimuli vanished, a target circle was then presented. Consequently, the degree of mislocalization toward the subjective and luminance contours was the same; this indicated that image integration at a coarse spatial scale cannot explain mislocalization. Experiment 2 revealed that the mislocalization in Experiment 1 was not a result of eye movements. Experiment 3 found that the spatial attention allocated at the location of the luminance and subjective contours was more than that allocated at the no-contour stimulus. An attentional shift toward the task-irrelevant stimulus resulted in a mislocalization of the target.

Notes
Ryan’s test adopts nominal significant level given as follows: p = 2 × 0.05/(n × (m − 1)), where n means the number of group to be compared, and m means the distance defined as the number of group X p satisfying X i ≤ X p ≤ X j . Here, X i and X j are pair in a concerned hypothesis. On the other hand, the significant level in Bonferroni’s test is set at p = 0.05/ n C 2, where n means the number of group to be compared.
