Visual Mental Imagery

2015
Opinions diverge on the nature of visual mental imagery as a form of representation. Researchers adopting the pictorial position propose that visual mental imagery is concrete and pictorial in nature. Researchers adopting the propositional position believe that visual mental imagery is abstract and verbal in nature and deny images as an original form ...

Autobiographical Recall and Visual Imagery

Perceptual and Motor Skills, 1996
If high visual imagery is a component of successful autobiographical recall for personal episodes, then those participants who have high imagery should have greater autobiographical recall for personal episodes. This hypothesis was tested by giving 30 selected participants, 15 who had high and 15 low visual imagery, 90 sec. to recall personal episodic

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.

Visualization of multimodality cardiac imagery

IEEE Transactions on Biomedical Engineering, 1990
A large number of clinically important and medically difficult decisions in diagnostic radiology involve interpreting the information derived from multiple imaging modalities. This is especially true in the assessment of heart disease, wherein at least two types of image information are generally required prior to deciding on the course of action ...

Visual imagery and electroencephalographic changes

Electroencephalography and Clinical Neurophysiology, 1956
Abstract The changes in the electroencephalogram relating to active vision, visual imagery, recall, and visual-motor performance were studied in a group of 180 psychiatric patients, and in 15 blind adolescent students. The conclusions from this study are as follows: 1. 1.

Visual Imagery in Hemianopic Patients

Journal of Cognitive Neuroscience, 2001
Abstract In this article we report some findings about visual imagery in patients with stable homonymous hemianopia compared to healthy control subjects. These findings were obtained by analyzing the gaze control through recording of eye movements in different phases of viewing and imagery.

Visual imagery and evoked-responses

Psychological Research, 1978
Two experiments were performed to determine whether a physiological correlate of visual imagery could be measured from visually-evoked-responses (VERs). ‘High’ and ‘Low’ imagery groups were used. There was no direct effect of imagery, although some differences between the groups emerged.

Cortical blindness and visual imagery

Neurology, 1995
Controversy exists concerning the neural basis underlying visual imagery. Some propose that visual images evoked from memory are mediated by primary visual cortices. Others argue that these primary visual areas perform computations on elementary visual features when constructing visual representations from retinal input but that they are not activated ...

Two Modes of Visual Imagery

Perceptual and Motor Skills, 1974
The relationship between active thought imagery and a passive, spontaneous mode of mental imagery is examined with regard to vividness. Results showed a significant consistency within the two modes but the relationship between modes remains unclear. Distinction between modes may be important in the design of research on imagery.

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.
