Psychophysical studies of monkey vision. I. Macaque luminosity and color vision tests.
Macaque monkeys and normal human observers were tested on the same apparatus for the presence of a Purkinje shift. and for spectral sensitivity under scotopic and photopic conditions. The flicker fusion point for different lights was used as a measure of visual sensitivity in these tests and the testing procedure was a four-alternative forced choice. The results show that macaque monkeys and no...
متن کاملColor Play: Gamification for Color Vision Study
The study of color perception in humans is an important ongoing research which currently mainly relies on psychophysical studies. Most psychophysical studies are prune to limitations which can highly reduce the scalability and repeatability of their experiments, cause over-fitting, and fail to fully engage subjects in performing the given tasks. Gamification is becoming a popular approach in ob...
متن کامل[Vision measurement and psychophysical tests].
Vision measurement is the basis for the study and standardization of visual sciences. Measurement of visual acuity has great value for research and for clinical practice. This paper (1) reviews the fundamental concepts to understand visual sense and the measuring units; (2) presents the fundamental limits to visual performance and the principles of aberration measurement of the eye; and (3) dis...
متن کاملImpairment of color spatial vision in chronic alcoholism measured by psychophysical methods
We used psychophysical tests to evaluate spatial vision in 15 subjects with a clinical history of chronic alcoholism by measuring luminance contrast sensitivity and color discrimination. The subjects were initially subjected to clinical inquiry and ophthalmological exam. Subjects then performed psychophysical tests to measure spatial contrast thresholds using sine wave gratings of different spa...
متن کاملShift of Equiluminance in Congenital Color Vision Deficiencies: Pattern-ERG, VEP and Psychophysical Findings
We compared electrophysiological responses [pattern-ERG (PERG) and VEP] and psychophysical measures to color stimuli to separate different forms of anomalous color vision. PERG and VEP were recorded from seven normals and 14 subjects with congenital color vision deficiencies. Stimuli were color checkerboards with 0.5 deg check size, phase reversing at 34 rev/sec. The luminances of the red and g...
