The most basic perceptual organization is

• Shape Constancy
• Depth Perception
• Figure-Ground
• Size Constancy

When traveling in a car, near objects seem to move past you faster than distant objects. This is called

• Aerial Perspective
• Linear Perspective
• Relative Size
• Relative Motion

The Moon Illusion is 

• caused by magnification of the moon's image by the atmosphere.
• based on the additional depth cues that exist when the moon is near the horizon.
• occurs only when the moon is closest to the earth.
• a special case of motion parallax caused by the moon's position overhead.

Motion Parallax

• alone is enough to indicate depth when most other cues fail.
• refers to the illusion that distant objects move slightly against a background, while closer objects move a sizable distance.
• accounts for much of the apparent depth in movies and animated cartoons.
• all of these

The illusion that railroad tracks come together in the distance involves the depth cue of

• atmospheric perspective
• texture gradiant
• light and shadow
• linear perspective

The most basic source of normal depth perception and stereoscopic vision is

• accomodation
• convergence
• retinal disparity
• linera perspective

In making a charcoal pencil drawing, which pictorial depth cue could you most effectively use?

• accomodation
• retinal fusion
• convergence
• light and shadow

__________ processing is like putting together a picture puzzle you've seen many times.

• Bottom-up
• Top-down
• Left-right
• Selective

Even though the retinal image of an object may change drastically, the object appears unchanged. This is the principle underlying

• perceptual closure.
• shape constancy.
• ambiguous stimuli.
• retinal disparity.

Patterns that break up figure-ground organization are known as

• closure.
• continuity.
• camouflage.
• contiguity.
