Which of the following is NOT a process of classical conditioning that Pavlov explored?

• A. Extinction
• B. Operant reinforcement
• C. Spontaneous recovery
• D. Generalization

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the key processes involved in classical conditioning as studied by Pavlov. These include acquisition, extinction, spontaneous recovery, generalization, and discrimination.
2. Step 2: Define each process briefly: Extinction is the weakening of the conditioned response when the conditioned stimulus is repeatedly presented without the unconditioned stimulus; Spontaneous recovery is the reappearance of the conditioned response after a rest period following extinction; Generalization is the tendency to respond to stimuli similar to the conditioned stimulus.
3. Step 3: Recognize that operant reinforcement is not part of classical conditioning but rather a concept from operant conditioning, which involves strengthening or weakening behaviors through rewards or punishments.
4. Step 4: Compare the options given and identify which one does not fit within the classical conditioning framework based on the definitions and Pavlov's research.
5. Step 5: Conclude that 'Operant reinforcement' is the process not explored by Pavlov in classical conditioning, as it belongs to a different learning theory.
