Final answer:
Determining a schedule of reinforcement is not part of classical conditioning but is a step in operant conditioning.
Step-by-step explanation:
The step that is NOT a part of classical conditioning is B. Determining a schedule of reinforcement. This step is a part of operant conditioning, not classical conditioning. Classical conditioning involves pairing a neutral stimulus (like a bell) with an unconditioned stimulus (such as food) which naturally and automatically elicits an unconditioned response (like salivation in dogs). After several pairings, the neutral stimulus becomes a conditioned stimulus on its own, capable of triggering a similar response, now called the conditioned response. The steps involved in classical conditioning are selecting the stimuli, establishing the conditioned response through acquisition, and testing for conditioning to see if the neutral stimulus has become a conditioned stimulus.
