Racial and ethnic stereotypes can sometimes bias our perceptions of others' behaviors. This best illustrates the impact of: 

• Retinal disparity

• Interposition

• Top-down processing

• Perceptual adaptation

The fact that perceptions involve more than the sum of our sensations best illustrates the importance of:

• top-down processing

• interposition

• retinal disparity

• visual capture

Which of the following is true?

• Humans cannot sense stimuli below the absolute threshold.

• Humans cannot be affected by stimuli below the absolute threshold at all.

• Stimuli presented below the absolute threshold can have a subtle, brief effect on behavior.

• Stimuli presented below the absolute threshold exert a strong, powerful effect on behavior.

If you move your watchband up your wrist an inch or so, you will feel it for only a few moments. This best illustrates:

• parallel processing

• accomodation

• sensory adaptation

• Weber's law

As we look at a flower, the intensity of the color we see is related to the light wave’s:

• amplitude

• hue

• length

• placement on the spectrum

The eye’s “blind spot” is related to:

• light rays focusing too far in front of the retina.

• light rays focusing too far behind the retina.

• a cluster of cells around the fovea which contains cones, but no rods.

• an area without receptor cells where the optic nerve leaves the eye.

Rather than saying a person is “colorblind,” it would be more accurate to say that the person:

• has a blind spot

• lacks red or green sensitive cones

• is experiencing an overstimulation of the red- and green- sensitive cones.

• has an excess of blue-sensitive cones

What is umami?

• a savory, meaty taste sensation for which researchers recently discovered receptors on the tongue

• receptors on the tongue that respond only to bitter tastes

• receptors on the tongue that allow us to taste nutrients in food, such as proteins and vitamins

• a condition in which there is a loss of the sensation of taste

The hammer, anvil, and stirrup are found in the:

• middle ear

• inner ear

• cochlea

• outer ear

As you talk with a friend at a party, her voice is distinct from all the other voices you hear. This illustrates the perceptual principle of:

• grouping

• proximity

• closure

• figure-ground
