Visual awareness revived by the physical disappearance of a perceptually faded object

Abstract (in Japanese) (See Japanese page) 
(in English) We investigated the effect of a physical offset of an invisible object on visual awareness using motion-induced blindness (MIB). The two objects (a target object and an outlined object) were presented nearby to each other. When observers reported that both objects perceptualy disappear, the invisible outlined object physically was excluded. We found that the invisible offset leads to the recovery of visual awareness of the target object. When the invisible offset occurs up to about 1 deg of visual angle around the target object, the awareness recovery by the offset persisted. Also, as the time passed after the perceptual disappearance of both objects, the invisible offset speeded the recovery of visual awareness from MIB. Moreover, we indicated a possibility that the awareness was recovered before the detection of the invisible offset. These results were discussed in terms of visual attention accompanied with the transient change of neural representations due to the invisible offset.
