- Q1
A collection of neurons and supportive tissue running from the base of the brain down the center of the back, protected by a column of bones, is called the:
Cerebellum
Somatic Nervous System
Amygdala
Spinal Cord
45s - Q2
Keegan notices that his favorite 55¢ candy bar seems lighter than usual so he checks the label and finds that it is lighter by half an ounce. He decides to buy a larger candy bar instead and doesn't notice that the 99¢ candy bar is also lighter than it used to be by half an ounce. Keegan's behavior illustrates the fact that:
The just noticeable difference is not reliable measure of psychophysiological judgement.
The larger a weight is, the greater change must be before one can detect a difference.
Sensory adaptation may occur in the short time between holding one candy bar and then the other.
It is unpredictable because sometimes he can and sometimes he cannot detect a half ounce change.
45s - Q3
Which of the following neurotransmitters function as the major inhibitory neurotransmitter in the brain?
Glutamate
Norepinephrine
Acetylcholine
GABA
45s - Q4
Melatonin helps to regulate daily biological rhythms and promotes sleep.
truefalseTrue or False45s - Q5
In addition to a subject's sensory capacity, signal detection theory takes into account.
The tendency for the subject's performance to worsen over time.
The subject's response bias
The tendency for the subjects performance to improve over time.
The amount of practice a subject has had.
45s - Q6
The information from rods and cones is communicated to ganglion cells by:
Opponent-Process Cells
Feature-Detector Cells
Bipolar Cells
Optic Disks
45s - Q7
The Sympathetic Nervous System enables the body to conserve and store its energy.
falsetrueTrue or False45s - Q8
Air serve as the only transmitting substance for sound waves:
falsetrueTrue or False45s - Q9
It is most difficult for humans to localize sounds that are coming from directly in back of them or directly above their heads:
truefalseTrue or False45s - Q10
An EEG or brain wave recording:
Is done with the help of electrodes taped onto the scalp.
Can precisely locate the source of activity
Reflects the activities of only a few cells at a time.
Is recorded by inserting needle electrodes into the brain.
45s - Q11
On a hike through the hills, Time feels a bug crawling up his leg under his pants. Which system is necessary for Time to be aware of the bug.
Somatic Nervous System
Sympathetic Nervous System
Endocrine System
Autonomic Nervous System
45s - Q12
Nerve impulses travel more slowly in babies than in older children and adults because:
Dendrites and axons take time to develop in infants
Neurons are much shorter in infants than in adults
The myelin sheaths on axons are not yet fully developed in infants
An infant does not have as many synaptic connections as an adult has.
45s - Q13
In order to infer an objet's location, we estimate its distance forms through both binocular and monocular cues.
truefalseTrue or False45s - Q14
The process by which a neuron gets its message across the synaptic cleft to another cell is best likened to:
Dead tree limbs being pruned from a tree
Electricity traveling along a telephone wire.
Fire traveling along the fuse of a firecracker
Sailors carrying a message from one island to another
45s - Q15
In blind people, the visual areas in the brain might be active during tasks requiring hearing or touch due to plasticity.
