Sensation and Perception Unit Test Review

1. The function of the lens is to

• Locate an image

• Focus an image on the retina

• Combine the location and projection on the blind spot

• Project an image on the cornea

Brain cells that analyze incoming sensory information into lines, angles, shading, and movement are called

• Sight cells

• Second stage sensors

• Feature detectors

• Vision neurons

Frequency is to _________________ as amplitude is to __________________.

• Compression; rarefaction

• Rarefaction; compression

• Pitch; loudness

• Loudness; pitch

The cones of the retina

• are densely packed in an area called the fovea

• are specialized for black and white sensations

• function best in dim light

• are not well specialized for fine detail

That you do not hear the noise of your family as you do your online school work is a good example of

• Sensory gating

• Sensory adaptation

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

• Linear perspective

• Relative height

• Relative size

• Relative motion

As a door opens toward you, you perceive it as a rectangular door rather than going through actual image changes on the retina (from a rectangle to trapezoid). This is an example of

• Perceptual closure

• Shape constancy

• Brightness constancy

• Retinal disparity

A cheetah scrambling up a rocky slope in Montana is likely to be perceived as a mountain lion because

• Perception is guided by expectations

• Figure and ground have been confused

• Contiguity is a powerful influence on perception

• The setting provides an ideal camouflage

After a few minutes in the hot tub Veronica declared, “It was hot when I first got in, but now my body is used to it. Come on in!” Veronica’s body became accustomed to the water due to

• Perceptual set

• Absolute threshold
