Selective Deficit of Mental Visual Imagery With Intact Primary Visual Cortex and Visual Perception

open access: yesCortex, 2008
There is a vigorous debate as to whether visual perception and imagery share the same neuronal networks, whether the primary visual cortex is necessarily involved in visual imagery, and whether visual imagery functions are lateralized in the brain.

Controllability of Motor Imagery and Transformation of Visual Imagery

Perceptual and Motor Skills, 1994
This study examined the relation between control of motor imagery and generation and transformation of visual imagery by testing 54 subjects. We used two measures of the Controllability of Motor Imagery test to evaluate the ability to control motor imagery.

Visual Imagery: A Case Study

Quarterly Journal of Experimental Psychology, 1974
This paper describes the performance of a subject who, when presented with a word or a sentence, is abnormally proficient at spelling this material in reverse order. She reports that she does this by visualizing this material and reading off from this visual image. Her tachistoscopic performance is also abnormally good.

Reliability of a Measure of Visual Imagery

Perceptual and Motor Skills, 1977
The resurgence of interest in visual imagery has generated a number of studies concerned with the reliability of tests purporting to measure the ability to form visual images. Typically results have shown such tests to be internally consistent but not impressively reliable over time.

Visual Imagery and Hypnotic Susceptibility

Perceptual and Motor Skills, 1974
A dot-pattern test for accuracy of imagery and the Betts QMI scale for vividness of self-reported imagery were administered to 10 Ss high and 10 Ss low in hypnotic susceptibility. As in previous studies, susceptibility and Betts scale responses were related, but neither was related to dot-pattern performance.

Visual Imagery on Brain Stimulation

Archives of General Psychiatry, 1968
THIS paper summarizes visual events reported by patients with intractable temporal lobe epilepsy when brain tissue was stimulated by means of depth electrodes. The study of such visual events yields information pertinent to the processes involved in perception, memory, and imagery formation.

On Visual Realism of Synthesized Imagery

Proceedings of the IEEE, 2013
Traditionally, computer graphics has been concerned with producing imagery that is as physically accurate as possible. But accurate physical simulation of geometry, lighting, and material properties of a visual scene can be cumbersome and time consuming. At the same time, human vision is far from accurate, which offers an enormous opportunity to create

Visualization and visual imagery: an overview.

Journal of the American Optometric Association, 1981
Visualization is a major aspect of overall consciousness and human information processing. This paper attempts to establish some of the common elements that lie behind the diverse ways that the terms visualization and visual imagery are used.
