Dichoptic stimulation
|
|
Dichoptic stimulation When different images are presented to each eye.
RELATED TERMS--------------------------------------
Eye
The organ of sight. The eye has a number of components. These components include but are not limited to the cornea, iris, pupil, lens, retina, macula, optic nerve, choroid and vitreous.
SIMILAR TERMS--------------------------------------
Dichromatic color vision
Color vision based on two cone photoreceptor pigments in the retina.
PREVIOUS AND NEXT TERMS--------------------------------------
Dark light
Rods spontaneously produce a signal that is indistinguishable from a photon elicited event even in complete darkness about once every 160 msec.
Degree of convergence
The angle of inclination of the two eyes used in depth perception
Delayed match-to-sample
Subject is shown a stimulus and then after a delay is required to choose the same stimulus from a number of stimuli to obtain reward.
Depth capture
Objects in an image with no apparent depth information can be captured by surrounding surfaces which do contain depth information.
Diaplopia
Double vision.
Dichoptic stimulation
Dichromatic color vision
Color vision based on two cone photoreceptor pigments in the retina.
Diffraction
The scattering of rays of light by collision with particles of matter as they pass through a medium such as air or water, or pass by a edge or narrow aperture. Plays a role when the pupil is small.
Direction selectivity
A difference in the response of a cell to a pattern of light moving through it receptive field according to the direction of movement. Cells respond well when a stimulus moves in one direction and not in the opposite direction.
Discounting the illuminant
Illumination of the visual world tens to be non-uniform, and fluctuates. in order for the visual system to create a consistent perception of color and lightness it must somehow discount fluctuation and gradient in the lighting source.
Disparity gradient
The ratio of the difference between two feature's disparities and their cyclopean separation. Steeply slanted surfaces have large disparity gradients. Human binocular fusion will only tolerate a disparity gradient of about 1.
