Buffy's increased heart rate and blood pressure when encountering the intersection exemplifies 'spontaneous recovery' in classical conditioning. This term describes the re-emergence of a conditioned response after a period without exposure to the conditioned stimulus. Therefore, the correct answer is D. spontaneous recovery.
;
In this scenario, Buffy experienced an increase in her blood pressure and heart rate when she entered the intersection of Crash and Burn, a location she had not visited for months. This is an example of spontaneous recovery in classical conditioning.
Spontaneous recovery occurs when a previously learned response suddenly re-emerges after some time has passed since the initial extinction of the conditioned response. In Buffy's case, her past experience at this intersection likely conditioned a physiological responseβperhaps due to a stressful or significant event that happened there previously. Even after not visiting the location for months, encountering the intersection again triggered her body's conditioned response.
Here's how it relates step-by-step to Buffy's experience:
Classical Conditioning History : Initially, Buffy might have associated the intersection with stress or anxiety, leading her body to respond with increased heart rate and blood pressure.
Extinction Period : Due to her change of jobs, Buffy did not visit the intersection for some time, potentially causing the conditioned response to diminish or 'extinguish'.
Unexpected Encounter : When Buffy unexpectedly passes through the intersection again, her physiological response re-emerges, demonstrating spontaneous recovery, even without the presence of the original stressor or reminder.
Thus, the correct multiple choice option is d) spontaneous recovery .
