The fact that spontaneous recovery occurs at all shows us that
A) an extinguished CS is still associated with the US.
B) classical conditioning is unique from operant conditioning.
C) stimulus discrimination is only possible with salient stimuli.
D) once a CS can elicit a CR, it is possible to serve as a US for another CS.

Question

Quizplus · Accepted Answer

Spontaneous recovery occurs when an extinguished conditioned response (CR) reappears after a period of time has passed. This suggests that the original association between the conditioned stimulus (CS) and unconditioned stimulus (US) is still present, which is why the CR can be elicited again. Therefore, option A, an extinguished CS is still associated with the US, is the best answer. Option B, classical conditioning being unique from operant conditioning, is not relevant to the concept of spontaneous recovery, while option C, stimulus discrimination only being possible with salient stimuli, is incorrect since discrimination is possible with all stimuli, not just salient ones. Finally, option D, that a CS can serve as a US for another CS, is not related to spontaneous recovery.
