threshold at all.

wrist an inch or so, you will feel it for
only a few moments. This best
illustrates:




A.
B.
C.
D.

the color we see is related to the light
wave’s:
A.
B.
C.
D.
amplitude.
hue.
length.
placement on the spectrum.
The eye’s “blind spot” is related to:
A. light rays focusing too far in front of the retina.
B. light rays focusing too far behind the retina.
C. a cluster of cells around the fovea which contains
cones, but no rods.
D. 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:
A. has a blind spot.
B. lacks red- or green-sensitive cones.
C. is experiencing an overstimulation of the red- and
green-sensitive cones.
D. has an excess of blue-sensitive cones.

middle ear.
inner ear.
cochlea.
outer ear.
What is umami?
A. a savory, meaty taste sensation for which
researchers recently discovered receptors on the
tongue
B. receptors on the tongue that respond only to
bitter tastes
C. receptors on the tongue that allow us to taste
nutrients in food, such as proteins and vitamins
D. a condition in which there is a loss of the
sensation of taste

requires you to use the absolute
threshold for sensation?
A.
B.
C.
D.
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

Your roommate, who has trouble
understanding Weber’s Law, asks you, “How
different do two stimuli need to be, in order
for a person to notice the difference?” You
explain that:
A. the stimuli must differ by at least ten percent.
B. the difference threshold decreases with the magnitude of
the stimulus.
C. the minimum difference needed for detection depends on
the type of stimulus.
D. Weber’s Law does not address this issue.
Researcher James Haxby (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:
A.
B.
C.
D.

As we perceive the environment, we use Gestalt principles
of good form to help organize things into meaningful
groups and forms. In observing a football game on TV we
are immediately able to recognize the players as members
of their respective teams, regardless of their positions on
the field. Which Gestalt principle is most responsible for
this ability?
A.
B.
C.
D.
closure
proximity
similarity
continuity
In the same football game, we watch as a team attempts a
field goal. Since the goal posts are distant and the time to
make a decision is short, the referee must use many
perceptual cues to decide whether the kick is good or not.
One important ability is depth perception. Which of the
following cues might be most helpful in deciding whether
the field goal is successful?
A.
B.
C.
D.
linear perspective
motion parallax
convergence
interposition
You are an artist and you are interested in completing a
painting that gives a three-dimensional appearance.
You want to show a beach in the foreground of the
painting, people swimming in the ocean, and sailboats in
the distance. Which perceptual principles will be most
helpful as you complete your painting?
A. binocular depth cues
B. monocular depth cues
C. Gestalt principles of proximity and continuity
D. perceptual principles only operate in “real life”
situations
You are most likely to observe the phi
phenomenon while:
A. looking at a string of Christmas tree lights that
