| Abstract(in English) | In this study, we investigated how proximity and closure cues interactively have an effect on object representations by analyzing the perceptual disappearance patterns of visual targets in motion-induced blindness (MIB). We presented two stimuli in which an inner target (a solid square) was embedded in an outer target (an outlined square), and asked participants to report whether the targets disappeared simultaneously or independently during MIB stimulus presentation (30s). In all experiments, we manipulated the distance between the targets and the contour closure of outer target. Especially, the former was manipulated systematically in Experiment 1, and the latter was manipulated systematically in Experiment 2. The results of both Experiments 1 and 2 showed that when the separation between the targets was 0.2deg, proximity cue most influenced the disappearance patterns of the targets, regardless of closure cue. Meanwhile, with the separation of 0.4deg, proximity and closure cues influenced the disappearance patterns of the targets cooperatively. Furthermore, with the separation of 0.6deg, closure cue most influenced the disappearance patterns of the targets. We showed that each perceptual grouping cue has a different effective spatial range. These results suggest that the visual system weights each perceptual grouping cue depending on the spatial distance between visual stimuli, and then the multiple perceptual grouping cues interactively affect object representations. |
