Document Summary

Absolute threshold: the lowest intensity at which a stimulus can be detected 50% of the time. Amplitude: the vertical size of a sound wave, which gives rise to the perception of loudness and is measured in terms of decibels (logarithmic) Basilar membrane: a membrane that runs the length of the cochlea and contains the organ of corti and its sound receptor hair cells. Binocular cues: depth cues that require the use of both eyes. Binocular disparity: the binocular depth cues produced by the projection of slightly different images of an object on the retinas of both eyes. Bipolar cells: the second layer of retinal cells with which the rods and cones synapse. Bottom-up processing: perceptual processing that begins with the analysis of individual elements of the stimulus and works up to the brain"s integration off them into a unified perception. Cochlea: a small coil-shaped structure of the inner ear that contains the receptors for sound.
