Late influences on perceptual grouping: Amodal completion
1Psychology Department, University of California, 94720, Berkeley, CA.
Abstract:
Perceptual grouping is generally assumed to be an early visual process that operates on a previously unorganized image-based representation. The present experiment shows that elements perceived as occluded by a closer surface tend to be grouped with elements having the same shape as the amodally completed percept rather than with those having the same retinal shape as the incomplete stimulus. It is therefore concluded that perceptual grouping by shape similarity either occurs after amodal completion or is a temporally extended process that occurs both before and after it.

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...

The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...
