Abstract
Visual object recognition was investigated in a group of eighty-one patients with right- or left-hemisphere lesions. Two tasks were used, one maximizing perceptual categorization by physical identity, the other maximizing semantic categorization by functional identity. The right-hemisphere group showed impairment on the perceptual categorization task and the left-hemisphere group were impaired on the semantic categorization task. The findings are discussed in terms of categorical stages of object recognition. A tentative model of their cerebral organization is suggested.

The striate cortex was studied in lightly anaesthetized macaque and spider monkeys by recording extracellularly from single units and stimulating the retinas with spots or patterns of light, with response properties very similar to those previously described in the cat.

The observations clearly indicate that impairment in facial recognition, as assessed by the procedures utilized in the study, is rather closely associated with disease of the right hemisphere.
CortexThe Contribution of the Right Parietal Lobe to Object Recognition

The findings provide evidence that gestalt formation is intact whereas perceptual classification is impaired in patients with right posterior lesions, and it was demonstrated that there is a favoured view for efficiency of object recognition.

The evidence strongly suggested that predicted IQ levels predicted from reading scores in a group of dementing patients provided close approximations to the premorbid IQ levels, and implied that reading ability is potentially a better indicator ofPremorbid level of functioning than vocabulary level.

Tasks of perceptual matching, including three types of visual stimulus (slope of line, position of dot and size of gap in contour) were devised, and the right parietal group was impaired on the perceptual matching tasks.

Visual discrimination of size, shade, shape and position was assessed in a group of 65 patients with unilateral cerebral lesions and although on the spatial task of position discrimination the right posterior group were impaired, discri mination ofsize, shade and shape were not significantly worse in theright posterior group than in the other patient groups.
PerceptionIllusion-Destruction by Appropriate Scaling
48 Citations1975Richard L Gregory, John P. Harris
The inappropriate constancy scaling theory of visual distortion illusions is tested by optically projecting typical models giving these figures by perspective and the prediction that when perspective and stereo are geometrically correct the distortion should vanish is confirmed.
