Break Down the Problem

1. Identify what the conditioned stimulus (CS) is in Pavlov's experiment.
2. Analyze the choices given to determine which is the correct option.

Relevant Concepts

1. In classical conditioning, the conditioned stimulus is the stimulus that initially has no effect but becomes associated with an unconditioned stimulus (US) through conditioning.
2. Pavlov’s experiment famously involved dogs, meat powder (the US), and a bell (the CS).

Analysis and Detail

1. Salivation to the meat powder - This is the unconditioned response (UR) that occurs naturally.
2. Bell - This is the sound that becomes the conditioned stimulus after being paired with the meat powder.
3. Meat powder - This acts as the unconditioned stimulus that naturally elicits salivation.
4. Dog - This is the subject of the experiment, not a stimulus.

Verify and Summarize

• The correct answer aligns with the definition of a conditioned stimulus; it refers specifically to the neutral stimulus (bell) that, after conditioning, elicits a conditioned response (salivation).

Final Answer

The conditioned stimulus (CS) in Pavlov's original experiment was the bell.
