Question 2

In the pain pathway, which neuron is responsible for transmitting the pain signal from the site of injury to the spinal cord?

Accepted Answer

Sensory neuron

Question 3

According to the diagram of pain perception, which system is primarily responsible for the emotional response to pain?

Accepted Answer

Motivational-affective system

Question 4

Which of the following best illustrates top-down processing in pain perception?

Accepted Answer

Expectations and beliefs about pain can reduce the perceived intensity of pain.

Question 5

In the Levine, Gordon & Fields (1978) study, what was the dependent variable (DV)?

Accepted Answer

Reported pain levels after dental surgery

Question 6

Which of the following is a function of pain according to psychological science?

Accepted Answer

Pain serves as a warning signal to protect the body from harm.

Question 7

Which brain region is most directly involved in the sensory-discriminative aspect of pain, as shown in the sensory cortex diagram?

Accepted Answer

Somatosensory cortex

Question 8

Phantom limb pain is best explained by which of the following?

Accepted Answer

The brain continues to receive signals from the area of the missing limb.

Question 9

Which of the following equations best represents the relationship between pain perception ($$P$$), biological ($$B$$), psychological ($$Psy$$), and social ($$S) $$factors?

Accepted Answer

$$P = B + Psy + S$$

Question 10

A patient reports pain in a limb that has been amputated. Which system in the pain perception diagram is most likely responsible for this experience?

Accepted Answer

Cognitive system

Question 11

Which of the following best describes the emergentist view of pain?

Accepted Answer

Pain arises from the interaction of multiple levels, including biological, psychological, and social factors.

Question 12

In the pain pathway, what is the role of the interneuron?

Accepted Answer

It relays signals between sensory and motor neurons in the spinal cord.

Question 13

Which of the following is an example of a social influence on pain perception?

Accepted Answer

Observing others in pain can increase your own pain sensitivity.

Question 14

Which of the following best describes the function of the myelin sheath in pain transmission?

Accepted Answer

It increases the speed of action potential propagation along the axon.

Question 15

A patient receives a placebo and reports reduced pain. According to Levine et al. (1978), which mechanism is most likely involved?

Accepted Answer

Activation of endogenous opioid systems

Question 16

Which of the following best illustrates the reductionist view of pain?

Accepted Answer

Pain is solely a result of neural activity in the spinal cord and brain.

Question 17

Which equation best represents the effect of placebo and naloxone on pain perception, as shown in Levine et al. (1978)?

Accepted Answer

$$Pain_{Placebo+Naloxone} \u003e Pain_{Placebo} \u003c Pain_{Alone}$$

Question 18

Which of the following is a multi-step process in the biological level of pain perception?

Accepted Answer

Peripheral input activates sensory neurons, which transmit signals to the spinal cord, then projection neurons relay the signal to the brain.

Question 19

Which of the following best describes the role of the motor response mechanism in pain perception?

Accepted Answer

It initiates protective actions such as withdrawal from a painful stimulus.

Question 20

Which of the following is an example of how higher-level influences can affect lower-level pain processing?

Accepted Answer

Cognitive expectations can reduce the activation of sensory neurons.
