Classical Conditioning Notes

AP Psychology: Classical Conditioning

Introduction

  • Unit 3: Development & Learning.

  • Classical Conditioning: A type of learning where an initially neutral stimulus, when paired with a stimulus that elicits a reflex response, results in a learned, or conditioned, response when the now conditioned stimulus is presented.

  • Associative Learning: Classical conditioning is a form of associative learning.

Key Terms

  • Unconditioned Stimulus (UCS): A stimulus that elicits an automatic or involuntary response.

  • Unconditioned Response (UCR): Any original response that occurs naturally and in the absence of conditioning.

  • Neutral Stimulus (NS): A stimulus that initially does not elicit the reflex or automatic response being studied.

  • Conditioned Stimulus (CS): A neutral stimulus that is repeatedly paired with an unconditioned stimulus until it acquires the ability to elicit a response that it previously did not.

  • Conditioned Response (CR): The learned or acquired response to a conditioned stimulus.

Processes

  • Acquisition: The first stages of learning when a conditioned response is established.

  • Extinction: The decrease or disappearance of a conditioned response.

  • Spontaneous Recovery: The reappearance of a conditioned response after a rest period or a period of lessened response.

  • Stimulus Generalization: The elicitation of a conditioned response by stimulation similar but not identical to the original stimulus.

  • Stimulus Discrimination: The ability to distinguish between different stimuli and respond differently to each.

  • Higher-Order Conditioning: Conditioning + CS = CR.

Figures

  • Ivan Pavlov: Pioneer in classical conditioning.

  • John B. Watson: Known for classically conditioned emotions. Quote: "I DON'T ALWAYS SCARE BABIES BUT WHEN I DO IT'S FOR PSYCHOLOGY."

Classical Conditioning Equations

  • UCS == UCR

  • CS == No Response

  • CS + UCS == UCR

  • CS == CR

Therapeutic Intervention & Counterconditioning

  • Counterconditioning: Changing the association of a stimuli to elicit a different response.

Taste Aversion

  • One-Trial Conditioning: Taste aversion can be learned in a single trial.

  • Biological Preparedness: Organisms are biologically predisposed to learn certain associations more easily than others.

Habituation

  • Habituation: Diminished response to an intermittent or enduring stimulus.
