opening of the eye through which light passes.
afferent neural pathway to visual cortex.

Gate Control Theory
explains the workings of the neural networks for pain.
location in the basiliar membrane makes sound.
how one is able to remain balanced.
remove wavelengths by mixing colors.
loss of sensitivity of receptors due to exposure.
frequency of vibrations creates sound.

Law of Pragnaz

filling in the missing parts to create a compete object.
the closer the object the greater detail that is seen.
objects remain their size and shape regardless of the size of proximal image.
the dominance of vision over the other senses.
the brain process of detecting differences in images to produce depth.
the process of seeing an object against a background.
Light & Shadow
depth cue related to the intensity of light shown upon an object.
a common test used for analyzing selective attention in subjects.
the ability to detect distance/depth by the amount we look inward.
distance cue related to speed of passing objects.
the apparent movement of a dot of light in a completely dark room.
depth cue requiring the use of only one eye.
schemas, experiences and contextual clues that change our perception of stimuli.
depth cue related to one object blocking the view of another object.
objects that are close to each other are perceived to be together.
a term in perception which means 'wholeness'.
