Step 1: Understand the key terms in classical conditioning. An unconditioned stimulus (US) naturally triggers a response without prior learning, such as pain causing fear.
Step 2: Identify the unconditioned response (UR), which is the natural, automatic reaction to the unconditioned stimulus, like fear in response to pain.
Step 3: Recognize the neutral stimulus (NS), which initially does not trigger the fear response, for example, the sight of a hypodermic needle before conditioning.
Step 4: Learn that through repeated pairing of the neutral stimulus (needle) with the unconditioned stimulus (pain), the neutral stimulus becomes a conditioned stimulus (CS).
Step 5: The child's learned fear at the sight of the needle is now a conditioned response (CR), which is the learned reaction to the previously neutral stimulus.
