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 …

Eye movements were recorded while subjects viewed a Kopfermann-like series of Necker
cubes and signaled perceptual reversals. At the instant of reversal, subjects tend to fixate the …

The removal of right-angle sectors from four circular black disks created the impression of a
white “subjective” square with its four corners occluding the disks (“illusory contours”). The …

The best known example of illusory figures is the Kanizsa triangle consisting of three disks
with a sector removed. The disks and sectors are arranged so that they form the corners of a …

Davis and Driver presented evidence suggesting that Kanizsa-type subjective contours
could be detected in a visual search task in a time that is independent of the number of …

Studies on the involvement of object completions in search for illusory figures have so far
reported equivocal results. We have addressed this issue by investigating at which level …

Abstract AM Treisman and G. Gelade (see record 1980-04685-001) proposed that in
searching for a target defined as a conjunction of 2 or more separable features, attention …

The individual differences in processing obtained by Hock (1973) were extended to two
experiments in which the embedded figures test was recast into the form of a yes-no reaction …

Observers searched for a horizontal line segment through displays containing varying
numbers of elements differing from the target and from each other in terms of orientation …

Projected slides of 112 coherent or jumbled real-world scenes for single-object detection by
36 introductory psychology students. The speed at which objects were detected was …
