Complexity effects in form detection
(Elsevier, 1977)
This study examines the effect of pattern complexity on the detectability of dotted target patterns presented in dotted visual noise. The effects of complexity on performance in this detection task were shown to be ...
Interactions of the horizontal and vertical human oculomotor systems: The saccadic systems
(Elsevier, 1972-01)
The human oculomotor system has been studied by numerous people for well over half a century. Since the visual system is our primary sensory input channel, it is important for us to know how information is processed by the ...
The effect of deviations from linearity on the detection of dotted line patterns,
(Elsevier, 1973-11)
Four experiments were carried out to determine the detectability of dotted line stimulus patterns embedded in backgrounds of randomly dotted visual noise. The results indicate that straight lines are more easily detected ...
The kinetics of cone visual pigments in man
(Elsevier, 1971-06)
Rushton's general kinetic equation for human cone pigments is tested by estimating the photolysis rate at equilibrium from the initial photolysis rate and comparing it to the equilibrium rate of regeneration measured ...
Opponent-process additivity--III : Effect of moderate chromatic adaptation
(Elsevier, 1975-10)
The luminance invariance and additivity of opponent-color equilibria were tested under conditions of chromatic adaptation to unique blue, green, yellow and to (nonunique) 650-nm red lights, varying from about 40 to 2000 ...
Wavelength discrimination by the goldfish near absolute visual threshold
(Elsevier, 1978)
Goldfish were classically conditioned to discriminate between 532 nm and 636 nm lights while light adapted, and then tested for their ability to continue the discrimination as the intensities were reduced. In all tests, ...
Relative modulation sensitivities of the red and green color mechanisms
(Elsevier, 1978)
The sensitivities of the human green and red cone mechanisms to sinusiodally flickering light were found to be near equal and independent of field size and estimation method. No wavelength dependency of modulation sensitivity ...
The effect of bleaching and backgrounds on pupil size
(Elsevier, 1972-05)
Measurements of pupil size and retinal rhodopsin in the dark after a full bleach confirm the suggestion of Alpern and Campbell that pupil dia. is linearly related to the fraction of unregenerated rhodopsin. This provides ...
