| A teacher used distortion googgles, which shifted the wearer's , to show an altered perception. A student wearing goggles bumped into numerous while walking around, but after minutes of wearing them was able to avoid obstacles, showing the concept of | perceptual adaptation |
| What do we call the illusion of movement the results from two or more stationary, adjacent light blinking on and off in quick succession. | phi phenomenon |
| Bryanna and Charles are in a dancing competition. It is easy for spectators to see them against the dance floor because of | figure-ground relationship |
| Narmeen is seeingthe board in the classroom. she knows that the board is far away because the view from her left eye is slightly different than the view from her right eye. Her ability to judge the distance of the board is due to which depth cue? | retinal disparity |
| Which of the statements is best explained by research on depth perception visual cliff human infants must learn to perceive depth monocular depth cues develop before binocular depth cues human infants are born with an innate sense of depth | human infants are born with an innate sense of depth |
| Even though the banana seemed to change color as the lighting in the room changed, Jane knew that the color of the banana was not actually changing. This is due to: | color constancy |
| What term describes the continuation of a visual sensation after removal of the stimulus? | afterimage |
| ________ disparity refers to the slightly different view of the world that each eye receives, and is a distance cue that allows us to perceive the depth of a given visual stimulus. | Binocular |
| Which nerve carries visual information from the retina to the brain? | optic |
| Wesley is in a movie theater with no windows—the only light is low illumination from the emergency lights on the floor. Which photoreceptors will be most useful to Wesley as he attempts to leave the theater? | rods |
| Which school of thinking in psychology includes the following concepts: figure-ground relationship, law of continuity, and principle of closure? | Gestalt |
| If you watch a flock of birds flying overhead, each very close to the next one, you may perceive them as all being part of the same group. This distinction takes advantage of which Gestalt principle? | proximity |
