Signal Detection Theory

A model for predicting how and when a person will detect a weak stimulus, partly based on context.

Weber’s Law

It is not the amount of change, but rather the percent of change that matters.

Chromostereopsis

Pure colors that are the same distance from the eye appear at different distances.

Rods and Cones

Rods give us sensitivity under dim lighting conditions and allow us to see at night, cones allow us to see fine details in bright light and gives us the sensation of color.

Parallel Processing

Ability to process and analyze many aspects of the situation at once.

Retinal Disparity

when viewing an object, it allows our left and right eye to view slightly different images. This binocular signal specifically provides information about distance.

Occlusion

An object that blocks the view of another object must be in front of it.

Relative Size

Smaller objects are further away.

Texture Gradient

As a texture gets further away it forms a smaller visual angles or pictures on the retina and less noticeable.

Relative Height

Objects that appear higher in our visual field are further away than objects that appear lower.
