Perceptual constancy allows you to perceive another person as a stable size even as they…

appear against backgrounds of varying textures.

move toward or away from you.

move into or out of shadow.

change apparent color because of different lighting conditions.

Both ambiguous figures and visual illusions demonstrate which of the following facts about human perception?

Group of answer choices:

Perception is not a simple reflection of objective reality.

Perception amounts to further processing of input from sensation.

Perception often involves the creation of a whole that is greater than the sum of its parts.

Perception operates in stages, beginning with simple operations and ending with complex ones.

When perceiving objects in the environment, the dorsal stream of the visual cortex processes the details of

Group of answer choices:

what objects there are.

how the objects relate to each other.

when (how long ago) the objects were seen.

where the objects are.

Regarding theories of color vision, what do opponent process theory and trichromatic theory have in common?

Both derive their basic principles from an understanding of how color vision was shaped by evolution.

Both explain how we can see complementary afterimages.

Both address the relationship between color vision and focus.

Both assume that a specific set of colors, rather than an open-ended continuum, are important to the visual system.

The wavelength of light waves is responsible for our perception of
