Questions and Answers

What is the purpose of the simplified cartoon depicting the neural circuit involved in Aplysia experiments?

  • To indicate the level of fatigue in Aplysia
  • To illustrate the process of habituation in Aplysia
  • To show the location of the change in the neural circuit (correct)
  • To highlight the sensory abilities of Aplysia

In Pavlovian conditioning, what is the difference between CS-US contiguity (Pavlov) and CS-US contingency (Rescorla)?

  • The type of conditioned response elicited
  • The timing of the CS and US presentations (correct)
  • The duration of the unconditioned response
  • The intensity of the conditioned stimulus

In the contingency space diagram, what does a point representing P(US|CS) = 0 and P(US|noCS) = 0 indicate?

  • Supports inhibitory conditioning to the CS
  • Indicates extinction of the conditioned response
  • Supports excitatory conditioning to the CS
  • Supports no conditioning to the CS (correct)
