| Abstract(in English) | When presented at an eccentric position in dynamic random-dots, the target is subjectively disappeared in a prolonged observation. Motion induced blindness (MIB) refers to this phenomenon. Here we examined the spatial extent of MIB. We defined MIB duration as the interval between the onset and offset of MIB of a circular target, which were reported by observers' key press and key release, respectively. In Experiment 1, a ring which did not overlap with the target was presented immediately after observers' key press, wherein the radius of the ring was varied trial by trial. MIB duration was significantly reduced in comparison with no-ring condition only when the ring radius was critically small. In Experiment 2, both the target and the ring flickering at 1Hz were presented for 60 sec, and observers were asked to continuously report disappearance/reappearance of the target in a similar way as used in Experiment 1. The results showed that the cumulative MIB duration of 60 sec significantly decreased only when the radius was critically small. These results indicate that MIB has a spatial zone, which may reflect spatial delimitation of object updating in visual recurrent processing. |
