Deck 31: Reaction Time: Biopac Exercise

Question 1

The response to laying one's hand on a hot stove is an example of a

A) stretch
B) cranial
C) voluntary
D) monosynaptic
E) withdrawal

Answer 1

E

Question 2

Voluntary responses of the body to internal or external environmental changes are automatic (not under our conscious control).

Answer 2

False

Question 3

Which of the following is NOT true of involuntary reflex responses?

A) They require the stimulation of specific receptors.
B) They occur more slowly than voluntary responses.
C) They require the transmission of nerve impulses.
D) They do not require input from the cerebral cortex.
E) They involve fewer neurons than voluntary responses.

Answer 3

B

Question 4

In the statistical calculations in this experiment, the square root of the variance is called the

A) deviation from the mean.
B) mean.
C) standard deviation.
D) median.
E) sum.

Question 5

In general, it would be expected that reaction time would get shorter between the first and the tenth stimuli in each condition that was tested, due to a learning process.

Question 6

In the statistical calculations for this experiment, the standard deviation in the fixed-interval reaction time experiment is usually lower than that of the random-interval reaction time experiment. What does this mean?

A) It means that average random-interval reaction times are typically shorter than average fixed-interval reaction times.
B) It means that there is less variability in the data for the fixed interval reaction time trials than in random-interval trials.
C) It means that average random-interval reaction times are typically longer than average fixed-interval reaction times.
D) It means that there is more variability in the data for the fixed interval reaction time trials than in random-interval trials.
E) It does not indicate any particular trend for fixed-interval vs. random-interval reaction time trials.

Question 7

For the class as a whole, which condition would you expect to display the shortest average reaction time?

A) Random interval, dominant hand
B) Fixed interval, dominant hand
C) Random interval, non-dominant hand
D) Fixed interval, non-dominant hand
E) All 4 of the conditions tested showed the same reaction times.

Question 8

Reaction times in this experiment were in the range of approximately

A) 1 to 4 msec.
B) 700 to 1,000 msec.
C) 1 to 4 sec.
D) 100 to 400 msec.
E) 7 to 10 msec.

Question 9

Neural pathways for voluntary and involuntary responses to stimuli are similar, but not identical.

Question 10

The reaction time for involuntary reflex responses is typically shorter than the reaction time in voluntary reactions.

Question 11

In the statistical calculations in this experiment, the average reaction time for all subjects in each condition is called the group

A) variance.
B) median.
C) standard deviation.
D) mean.
E) mode.

Question 12

All reflex arcs contain an interneuron.

Question 13

Which of the following represents the correct order of components in an involuntary spinal reflex arc?

A) Effector, sensory neuron, motor neuron, interneuron, sensory receptor
B) Sensory neuron, interneuron, sensory receptor, motor neuron, effector
C) Sensory receptor, sensory neuron, interneuron, motor neuron, effector
D) Interneuron, sensory receptor, sensory neuron, effector, motor neuron
E) Sensory receptor, motor neuron, interneuron, sensory neuron, effector

Question 14

The reaction time experiment is an example of a voluntary reaction.

Question 15

In a spinal reflex arc, the interneuron, if present, is found in the gray matter of the spinal cord.
