In an experiment a dog had been conditioned to salivate at the sight of food and a flash of light. After conditioning the reflex, the light was then paired with the bell. The dog didn’t start to salivate. What type of inhibition was observed?
- A. Extinctive
- B. Differential
- C. External
- D. Persistent
- E. Protective
Hint
The bell was added only after the reflex was established; ask what kind of cortical process a novel stimulus provokes and whether that process has to be learned or is inborn.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
