Chapter 4—Sensation
and Perception
MULTIPLE CHOICE
1.
Which of the following
reflects a distinction between the process of sensation and the process of
perception?
|
a.

Sensation is not necessary for perception
but perception is necessary for sensation.
|

Sensation reflects reality, while perception

that registers on sensory memory

set point

Werner was having his
hearing tested, and a number of the tones that were presented were so faint he
was not able to detect them. What can you say about the faint sounds?
|
a.
|
They fall below Werner’s absolute threshold
for sound.
|
|
b.
|
They cause more inhibitory than excitatory
PSPs.
|
|
c.
|
They cause action potentials that were too
weak to reach the terminal buttons.
|
|
d.
|
They fall below Werner’s adaptation level
for sound.

Juanita was drinking
some warm punch and she thought she could just detect a faint taste of nutmeg
in the punch. When she took another sip the taste wasn’t there. On the third
sip she could just make out the taste of nutmeg again. What could you say about
the taste of nutmeg in this situation?
|
a.
|
It falls just below her taste constancy
level.
|
|
b.
|
It produces inhibitory potentials rather
than excitatory potentials.
|
|
c.
|
It is just at her absolute threshold for
taste.
|
|
d.
|
It produces action potentials that were too
weak to reach the terminal buttons.

Giovanni was watching
the night sky on a clear evening in November. He noticed that sometimes when he
looked directly overhead he could detect a very faint star. A few minutes later
it seemed that the star had disappeared, and then it “appeared” again. How
would you describe the light from the star, in this case?
|
a.
|
It produces action potentials that were too
weak to reach the terminal buttons.
|
|
b.
|
It produces inhibitory potentials rather
than excitatory potentials.
|
|
c.
|
It falls just below Giovanni’s level for
perceptual invariance.
|
|
d.
|
It is just at Giovanni’s absolute threshold
for light.

Which of the following
is being measured if a subject is presented with a series of light bulb pairs
of different wattages and is asked whether the members of each pair differ in
brightness?
|
a.
|
subject’s visual acuity
|
|
b.
|
subject’s absolute threshold for brightness
|
|
c.
|
subject’s just noticeable difference for
brightness
|
|

|
physical intensity difference between the
two lights

If a 100-Hz tone had
to be increased to 110 Hz for a subject to just notice the difference, what
