Abstract:
The visual system often automatically perceives partially occluded objects as whole and complete. This phenomenon is called amodal completion, but its mechanism is not fully understood. In the first experiment, we measured the psychophysical time course of face amodal completion using a performance-based method and found the amodal completion took place between 100 and 300 ms after stimulus onset. In the second experiment, we found the amodal completion could modulate event-related potentials (ERPs) in the same time range. These results provide further evidence regarding the representational development of occluded faces from local facial features to a coherent face.

Perceptual Constancy
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...
