Exteroreceptors
Anteroceptors
Proprioceptors

Question 13
2!/ 2!pts
Match the type of cutaneous receptor to its function.
Meissner's corpuscles
are sensitive to flutter and are located in the superficial region of
glabrous skin (hairless skin) also known as the epidermis. These receptors
are rapidly adapting, and have very fine areas of sensitivity (as small a 2-4
mm) or one could say their receptive field is small.
Merkel receptors
are activated by steady skin indentations and are also located in
the epidermis of the skin. They are slow adapting receptors and their
receptive field is larger than at least one other type of cutaneous receptor.
Pacinian corpuscles
are activated by vibrations and are rapidly adapting. They are
located in the dermis (deep skin) and have large receptive fields (many
mm's).
Ruffini receptors
are activated by steady skin indentation and are slowly adapting.
These receptors are also located in dermis. Their receptive field is also
large.
I Question 14
0!/ 2!pts
Which system has one feature setting it apart from any other system?
Vision
Audition
Olfaction
None of the above, all systems have equal scientific importance
Question 15
2!/ 2!pts
How many major sensory modalities have been traditionally recognized?
Three
Four
Five
Six
Question 16
2!/ 2!pts
The optic chiasm is a gap in the retina due to the exit of the optic nerve
where no photoreceptors are located.
True
False
Question 17
2!/ 2!pts
The slight difference in degree the sound wave is moving through its wave
when it reaches one ear compared to the other
Interaural intensity difference
Two-process theory
Sound shadow
Phase difference
!
Question 18
2!/ 2!pts
The principle that the size of the difference threshold is relative to the
strength of the original stimulus is called:
The Just-Noticeable Difference
Weber's law
Absolute threshold
All of the above
Question 19
2!/ 2!pts
Top-down processing is an information-gathering process starting from each
individual stimulus.
True
False
Question 20
2!/ 2!pts

failure of accurate scene detection as if we are blind to that event.
Unintentional
Inattentional
Unattentional
Perceived
!
Question 21
2!/ 2!pts
A person’s _______ threshold is measured by taking the smallest amount of a
stimulus and gradually increasing its strength until a person correctly
guesses the stimulus’s presence 50% of the time.
Minimum
Difference
Absolute
Tolerance
Question 22

What is the difference between rods and cones?
Rods process colorful images in very high detail while cones process dim
light
Cones process colorful images in very high detail while rods process dim
light
Rods are photoreceptors and cones control the diameter of the pupil
Cones are photoreceptors and rods control the diameter of the pupil
