Perceptual constancy

• Objects are unchanging, regardless of changing stimuli (light, placement, etc.)

• Shape, location, brightness, & size

Perceptual Adaptation

• Anything that adjusts what you sense requires adjustment in your perception (e.g. new glasses = disorientation for a day).

• You can adapt to anything, even inverted sight, with enough time.

Perceptual Set

• Experiences, assumptions, and expectations influence what we perceive.

Explain

• How is your perceptual set related to perceptual constancy?
