Document Summary

Increased sensitivity to light following period of darkness. Process through which the eyes become less sensitive to light under high illumination. Area of retina that contains rods/cones which when stimulated a ects ring of speci c cells in. Stimulation at centre increases cell ring whereas stimulation o -centre inhibits cell ring. Occurs when neural activity in a cell opposes activity in surrounding cells. Neurons that respond selectively to speci c features of complex stimuli. Three di erent types of color receptors in the retina each sensitive to a speci c colour. Color perceived in three channels (red vs green, yellow vs blue, black vs white) Elements that are close to one another tend to be grouped together. Elements that are similar tend to be grouped together. Tend to supply missing elements to close or complete a gure. Tend to see elements in a way that appear continuous. Tend to organize elements simplest way possible. Binocular cues a) retinal disparity: convergence.
