AP Psych Review: Unit 3- Sensation and Perception

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
• sensory adaptation
• accomodation
• Weber's Law

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

• placement on the spectrum
• length
• hue
• amplitude

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:

• inner ear
• vestibular sacs
• middle ear
• outer ear

Makers of 3-D movies rely most heavily on:

• the visual cliff.
• The Lyer Illusion
• retinal disparity. 
• monocular cues. 

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: 

• sensation. 
• bottom up processing.
• perceptual sets

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

• telling the difference between sweet and salty
• detecting a tiny, faint light on a radar screen
• deciding if two glasses contain the same amount of water
• telling if your guitar is in tune

You are going to design an experiment to determine whether there are special areas on the tongue to detect the taste of sweet, or whether the taste can be detected in all areas of the tongue.  Which of these must be done before you can start the experiment?

• operationally define sweet.
• pick out subjects who like sweet tastes.
• pick out the items that you will use for sweet tastes.
• none of these are necessary.

Researcher James Hixby (2001) stated, “We can tell if a person is looking at a shoe, a chair, or a face, based on the pattern of their brain activity.”  This statement is relevant to:

• sensory adaptation
• feature detection
• opponent-process theory
• place theory
