Question: 31
1. Researchers repeatedly startle a participant with a loud buzzer. After some time, the participant stops being startled by the buzzer. If the researchers interrupt the study with the sound of pans banging together, which of the following would likely be observed?
- A. Increased startle response to the buzzer
- B. Decreased startle response to the buzzer
- C. No change in the response to the buzzer
- D. Generalization to previously nonaversive stimuli
Correct Answer: A
Explanation:
After a while, the participant became habituated to the sound of the buzzer. Introducing a new stimulus, such as the banging pans, should dishabituate (resensitize) the original stimulus, causing a temporary increase in response to the sound of the buzzer.
