IB Psychology 2.2.2 Classical Conditioning Notes

Classical Conditioning

Key Terminology

1. Unconditioned stimulus (UCS): A stimulus that naturally and automatically triggers a response without prior learning.
2. Unconditioned Response (UR): The natural, automatic reaction to the UCS.
3. Neural Stimulus: A stimulus that initially produces no specific response.
4. Conditioned Stimulus: A previously neutral stimulus that, after association with the UCS, triggers a conditioned response.
5. Conditioned Response: A learned response to the conditioned stimulus.

Pavlov's Dogs: The Birth of Classical Conditioning

Key Processes in Classical Conditioning

1. Acquisition: The initial stage where the NS is paired with the UCS to elicit the CR.
2. Extinction: The weakening of the CR when the CS is repeatedly presented without the UCS.
3. Spontaneous Recovery: The reappearance of the CR after a rest period following extinction.
4. Generalization: The tendency to respond to stimuli similar to the CS.
5. Discrimination: The ability to distinguish between the CS and other stimuli.

Applications of Classical Conditioning

Phobias

1. Classical conditioning explains how phobias develop when a neutral stimulus becomes associated with a fearful event.
2. Example: A person bitten by a dog may develop a fear of all dogs.

Advertising

1. Advertisers use classical conditioning to create positive associations with their products.
2. Example: Pairing a product with attractive celebrities to elicit positive emotions.

Strengths and Limitations of Classical Conditioning

Strengths

1. Simple and Observable: The process is straightforward and can be easily observed in experiments.
2. Testable: Classical conditioning can be tested and replicated in controlled settings.
3. Wide Applications: It explains a range of behaviors, from phobias to advertising strategies.

Limitations

1. Ignores Cognition : Classical conditioning doesn't account for thought processes or free will.
2. Limited to Reflexive Responses : It primarily explains automatic or reflexive behaviors, not complex actions.
