Sensory adaptation
The figure has more detail and stands out against the background which has less detail
Figure ground perception
Nearness of objects, we group together objects that are physically close to one another
Proximity
We tend to group object together that appear similar
Similarity
We favor smooth paths while interpreting a series of points or lines
Continuity
Connecting the dots is example of
Continuity
Perception of a complete figure, even when there are gaps in sensory information
Closure
Elements moving together are grouped together

Referred
Neuropathic

located in the center of the rintina called fovea
Allows use to see fine detail
Cones
Visual ability
Depth perception
2 eyes convergence
Cross=eye
Binocular
Monocular
One eye
For focusing
Lens
Colored part of the eye
Muscle that regulates the size of the opening in the eye
The Iris
Transparent eye cover
The cornea
Narrow opening in the center of the iris
Light enters the eye, sensitive to light and emotion
The Pupil
Sends neural impulse to brain
Optic Nerve
Light sensitive surface contains photoreceptors
Which are Rods and Cones
Retina
Easier to see closer
Eye ball is too LONG
Nearsightedness
The eyeball is too SHORT
Foresightedness
