Deck 7: Sensory Discrimination Functions and Disorders

Question 1

Instead of being relayed via the thalamus, output axons of the olfactory bulbs project directly to the olfactory cortex and parts of the limbic system.

Answer 1

True

Question 2

Proprioceptive discriminatory skills are incapable of refinement, despite practice via active engagement and functional use.

Answer 2

False

Question 3

The primary vestibular cortex is responsible for bodily functions such as postural control, balance, and coordination.

Answer 3

False

Question 4

The two main functions of spatial hearing are (1) enabling a person to localize sound sources, and (2) enabling a person to separate sounds based on where he or she is located.

Question 5

Throughout development, the dorsal stream used to guide movement matures earlier than the ventral stream used for object recognition.

Question 6

Discrimination skills can be difficult to assess in children because behavioral methods of assessing discrimination require attention and cooperation on the part of the participant.

Question 7

Peripheral receptors for tactile discrimination are evenly distributed across the surface of the skin and across all body regions.

Question 8

Research shows that handwriting skills are likely to improve when therapy addresses the underlying somatosensory deficits; rote practice of the skill is not essential to performance improvement.

Question 9

Hyposmia refers to the reduced ability to smell.

Question 10

Taste and smell are the only sensory systems contributing to flavor discrimination.

Question 11

Otolith organs within the vestibular system are primarily responsible for which of the following?

A)Linear head movement
B)Discrimination of whole-body motion
C)Static posture
D)a and c
E)b and c

Question 12

Which of the following is NOT a function of the dorsal visual stream?

A)Identifying objects in our environment
B)Understanding visual space
C)Detecting movement of objects through space
D)Locating objects in space

Question 13

Two-point discrimination is a test used to measure which of the following constructs?

A)Stereognosis
B)Kinesthesia
C)Tactile-spatial acuity
D)Touch localization

Question 14

Use of mismatch negativity (MMN) for testing auditory discrimination skills is preferred over other behavioral measures because ____________.

A)It can be measured in utero.
B)It can be elicited regardless of whether the subject is paying attention.
C)It is the most cost-effective method of assessing auditory discrimination in clinic settings.
D)It requires very little training or equipment to conduct.

Question 15

Which neural process involves activation of multiple neurons in combination and has been associated with both taste and smell discrimination?

A)Lateral inhibition
B)Sensory detection
C)Population coding
D)Mismatch negativity

Question 16

Odor discrimination can be influenced by all of the following EXCEPT _________.

A)Gender
B)Mood
C)Experience
D)Size of nasal cavity
