Pavlov and Classical Conditioning

Ivan Pavlov and Classical Conditioning

• Pavlov's research focused on the physiological aspects of digestion, leading to the development of classical conditioning theory.
• Pavlov observed that associating neutral stimuli with food caused animals to salivate.
• He used a bell as a neutral stimulus, initially unassociated with a response.
• With repeated pairings of the bell with food, the bell became a conditioned stimulus that triggered salivation (conditioned response).
• The unconditioned stimulus is the naturally occurring trigger (food), and the unconditioned response is the natural reaction (salivation).
• This learning process involved associating a previously neutral stimulus with a stimulus that naturally evokes a response.

Key Terms in Classical Conditioning

• Neutral Stimulus: A stimulus that initially does not evoke any specific response. (e.g., a bell before conditioning).
• Unconditioned Stimulus (UCS): A stimulus that naturally and automatically triggers a response. (e.g., food).
• Unconditioned Response (UCR): The unlearned, naturally occurring response to the unconditioned stimulus. (e.g., salivation to food).
• Conditioned Stimulus (CS): A previously neutral stimulus that, after association with an unconditioned stimulus, now triggers a conditioned response. (e.g., the bell after conditioning).
• Conditioned Response (CR): The learned response to a previously neutral stimulus. (e.g., salivation to the bell).

Pavlov's Experiment and the Learning Process

• Pavlov initially observed involuntary responses in his research on digestion, noting that stimuli related to food trigger salivation.
• He then tested the possibility of associating a new object with this reflex, and the dogs learned to associate the new object with food, leading to salivation.
• Pavlov discovered that dogs learned to associate a neutral stimulus (e.g., a bell) with food, eventually triggering a conditioned response of salivation in response to the bell alone.
• The procedure involved presenting the neutral stimulus (bell) just before the unconditioned stimulus (food) to establish the association.

Operant Conditioning vs. Classical Conditioning

• Operant conditioning, studied by Skinner, focuses on voluntary behaviors and their consequences (reinforcement or punishment).
• Classical conditioning, studied by Pavlov, focuses on involuntary responses and their associations with stimuli.
• In operant conditioning, the subject's actions influence the environment and subsequent rewards/punishments, but the subject generally anticipates these consequences. In classical conditioning, the response is automatic based on the previously established association between the neutral and unconditioned stimuli.
