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
• accommodation
• sensory adaptation
• Weber's law

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. 

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

• middle ear.

What is umami?

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

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.

Makers of 3-D movies rely most heavily on:

• the visual cliff.
• the Müller-Lyer illusion.
• retinal disparity.
• shape constancy.

After hearing that Bryce had served a prison sentence, Janet began to perceive his friendly behavior as insincere and manipulative. This best illustrates the impact of: 

• perceptual sets.
• visual capture.
• bottom-up processing.
• sensory adaptation.

If a person were able to sense that his friend’s dog was lost and needed help, this person would be said to have:

Which of the following activities requires you to use the absolute threshold for sensation?
