In Pavlov's experiment, what does the bell become AFTER conditioning has taken place?
AConditioned Stimulus (CS) that elicits a conditioned response
BUnconditioned Stimulus (US) that elicits a reflex response
CUnconditioned Response (UR) elicited by food directly
DNeutral stimulus with no relation to salivation at all
Answer & Solution
Correct answer: A. Conditioned Stimulus (CS) that elicits a conditioned response
1. Before conditioning, food acts as the Unconditioned Stimulus and salivation as the Unconditioned Response.
2. The bell is initially a neutral stimulus that only causes alertness, not salivation.
3. After repeated pairing with food, the bell alone triggers salivation in the dog.
4. At this stage the bell is renamed a Conditioned Stimulus.
5. Salivation to the bell becomes a Conditioned Response.
6. Hence after conditioning the bell is the Conditioned Stimulus.
