One way of perceptually organizing a complex visual scene is to attend selectively to
information in a particular physical location. Another way of reducing the complexity in the …

We show that early vision can use monocular cues to rapidly complete partially-occluded
objects. Visual search for easily-detected fragments becomes difficult when the completed …

The principle of uniform connectedness (SE Palmer and I. Rock, 1994) states that connected
regions of uniform visual properties correspond to the entry-level units of visual stimuli. The …

Four experiments examined whether Kanizsa subjective figures can induce amodal
completion of a notched circle at parallel stages of visual search. Search for the notched …

The purpose of this paper is to offer demonstrations of 'illusory volumes' in the spirit of the
illusory flat surfaces described by Kanizsa. These demonstrations of illusory volumes exploit …

Hens (Gallus gallus domesticus) were taught to peck at a touch screen. On the screen was a
grid on which a square and a circle were depicted. The square and the circle were given …

Perceptual closure is a process whereby an incomplete stimulus is perceived to be
complete. JG Snodgrass and K. Feenan (1990) argued that perceptual closure during a …

We report a new type of illusory contour (Illusory-O) whose formation is contingent upon the
contrast polarity of its juxtaposed inducing elements being similar, ie both elements must …

Recent evidence challenges the view that attention acts on the outputs of early filters
dedicated to processing motion, color, and orientation. Instead," proto-objects" specified by …

Global aspects of perceptual structure play an extremely important role in the recognition of
visual objects such as faces and vases. One might claim, therefore, that such global …
