D

As you walk into a brightly lit room, the black structure in the center of your eye seems to shrink to a tiny black dot. This response is caused by the action of the eye structure called the:

Iris

Railroad tracks appear to converge in the distance. This provides a cue for depth perception known as _____.

Linear perspective

Jasmine was in a serious car accident. She suffered damage to her temporal lobe, just behind her right ear. What kind of problems might this cause for her?

Trouble recognizing familiar faces

Suppose each pixel on a television screen or computer monitor codes the color of an image at that point in terms of red, blue, and green values. This closely resembles the way that:

color is represented in the retina

The transparent structure behind the pupil that changes shape to help focus images on the retina is called the:

lens

Relative luminance MOST clearly contributes to:

lightness constancy

In terms of vision, _____ is the ability to adjust to an artificially displaced or inverted visual field.

perceptual adaptation

Psychologist George Stratton conducted a famous experiment on perceptual adaptation in which he: A. wore a pair of glasses that inverted his vision for eight days. B.spent two weeks in a sensory-deprivation chamber. C. spent a week under heavy sedation. D. stayed in a room that was completely dark for one month.

A
