Definition of Cones in Psychology
Cones in Psychology
The definition of cones in psychology refers to one of the two kinds of photoreceptors in the eye; less numerous, shorter, thicker, and more highly concentrated in the foveal region of the retina than in the periphery of the retina than are rods (the other type of photoreceptor); virtually nonfunctional in dim light, but highly effective in bright light and essential to color vision.
