Sensation & Perception

Theory that opposing retinal processes(red-green,yellow-blue,white-black) enable color vision

Perceiving objects as having the same shape from different angles

Analysis that begins with the sensory receptors and works up to the brains sensory info

Perceiving objects as having the same brightness in different lighting

Binocular cue for perceiving depth by comparing images from the retinas in two eyes

Info processing by high-level metal processes, like constructing perception from experience

Transparent protective coating over the front part of the eye

The process where our sensory receptors & nervous system receive energy from the environment

The five basic tastes

The theory that the spinal cord blocks pain signals or allows them to pass on to the brain

According to Helmholtz Trichromatic Theory , the retina has color receptors for these colors

Retinal receptors that detect black,white, and gray; necessary for twilight vision

The sense of body movement and position, including sense of balance

Process that organizes sensory information and enable us to recognize meaningful events/things

Failing to see visible objects when our attention is directed elsewhere.

Perceiving future events

One of the two chemical senses, along with smell

Coiled, bony, fluid-filled tube in the inner ear where sound waves trigger neural impulses

Light-sensitive inner surface of the eye, contains receptor rods and cones

Sensing the tick of a watch at 20 feet under quiet conditions is an example of this hearing

Our sense of smell triggers memories because of this system in the brain

Number of complete wavelengths that pass a point in a give time, affects pitch in sound waves

The central focal point in the retina, where the eye's cones cluster around

Principle that, to be perceived as different , two stimuli must differ by a constant percentage

Perceiving objects as having the same size from different angles
