Stereoscopic acuity and observation distance.
Because of ihe contradictory evidence as to whether stereoscopic acuity varies with observation distance, this study was undertaken to investigate the problem, with the utmost care being taken to maintain constant experimental conditions and to eliminate empirical clues to depth perception. By means of a haploscopic apparatus, which allowed careful control of all parameters, the stereoscopic ac...
متن کاملStereoscopic acuity and observation distance.
The amount of depth perceived from a fixed pattern of horizontal disparities varies with viewing distance. We investigated whether thresholds for discriminating stereoscopic corrugations at a range of spatial frequencies were also affected by viewing distance or whether they were determined solely by the angular disparity in the stimulus prior to scaling. Although thresholds were found to be de...
متن کاملDistinct eye movement patterns enhance dynamic visual acuity
Dynamic visual acuity (DVA) is the ability to resolve fine spatial detail in dynamic objects during head fixation, or in static objects during head or body rotation. This ability is important for many activities such as ball sports, and a close relation has been shown between DVA and sports expertise. DVA tasks involve eye movements, yet, it is unclear which aspects of eye movements contribute ...
متن کاملStereoscopic and Resolution Acuity with Varying Field of View
Resolution and stereoscopic acuity were measured while the field of view was varied in size—without, however, obstructing the targets for either eye. Resolution acuity showed no marked or regular changes, but stereoacuity was progressively reduced as the field of view was constricted. This supports the hypothesis that the sharp decline in stereoacuity is due to loss of peripheral visual stimuli...
متن کاملMethodological Aspects of Cognitive Rehabilitation with Eye Movement Desensitization and Reprocessing (EMDR)
A variety of nervous system components such as medulla, pons, midbrain, cerebellum, basal ganglia, parietal, frontal and occipital lobes have role in Eye Movement Desensitization and Reprocessing (EMDR) processes. The eye movement is done simultaneously for attracting client's attention to an external stimulus while concentrating on a certain internal subject. Eye movement guided by therapist i...
