TL;DR
Multivariate analyses indicated that there was substantial age-related variance in all CTs, while sex was variably significant; CTs are not uniform in their discriminating ability, and hence factorially complex; and their specifically right hemisphere-sensitive dimension was subjective contour illusions, and interestingly unrelated to facial discrimination ability.
Abstract
This study investigates the construct validity of perceptual closure tests (CTs), and isolates a common processing demand from the right-hemisphere. Sixty-seven patients with focal unilateral lesions (34 right side, 33 left side), and 80 control subjects participated. Multivariate analyses indicated that there was substantial age-related variance in all CTs, while sex was variably significant; CTs are not uniform in their discriminating ability, and hence factorially complex; and their specifically right hemisphere-sensitive dimension was subjective contour illusions, and interestingly unrelated to facial discrimination ability. The methodological and theoretical implications are discussed.

It was shown that depth can be perceived in the absence of monocular depth and familiarity cues and of all binocular depth cues except for disparity, and it has been demonstrated that the perception of ambiguous depth organizations can be influenced, even subliminally, by a preceding unambiguous stimulus.

187 Citations1980Ruben C. Gur
Results from regional cerebral blood flow as measured by the 133Xe inhalation method show that such individual differences can be detected in the distribution of blood in the two hemispheres and that the amount of increase in blood flow in the right relative to the left hemisphere is correlated with performance on a spatial task.
PerceptionIllusory Contours as the Solution to a Problem
171 Citations1979Irvin Rock, Richard H. Anson
The perception of certain figures with illusory contours entails a reversal of figure and ground and it is hypothesized that this process occurs in two stages, namely, alignment of physically present contours, recognition of parts of the stimulus array, and set.

The test performances of 185 adult patients with established diagnoses of brain disease and 151 adult patients without history or evidence of brain health were studied to explore the possibility of developing a valid abbreviated form of the Test of Facial Recognition of Benton and Van Allen for clinical use.
Perception & PsychophysicsIllusory contours and stereo depth
90 Citations1974Richard L Gregory, J. P. Harris
It is suggested that nearer masking objects are perceptually postulated to “account” for gaps when these are unlikely, and when stereoscopic depth information incompatible with this “perceptual hypothesis” is presented, the illusory contours are reduced in intensity or disappear.

A relationship between depth perception and the perception of anomalous contours has been suggested and a conventional stereoacuity test and a test of random-letter stereopsis were given to patients with unilateral right hemisphere lesions to test this hypothesis.

Performance on tasks sensitive to right hemisphere dysfunction (facial discrimination and perceptual closure) are reported in eight patients with right hemisphere lesions, and patients demonstrated an apparent double dissociation of performance on the two measures.

By investigating gestalt completion, this work suggests that the cognitive factors underlying appositional abilities can be better understood, and ethnic differences in performance can be understood.
