Study Guide: Learning Theories in Psychology

Chapter 7: Learning Theories

Introduction to Learning Theories

Learning theories in psychology explain how individuals acquire, modify, and reinforce behaviors through experience. This chapter focuses on classical and operant conditioning, foundational concepts in behavioral psychology.

• Classical Conditioning: Learning through association between stimuli.

• Operant Conditioning: Learning through consequences, such as rewards and punishments.

• Stimulus Generalization: Responding similarly to different but related stimuli.

• Stimulus Discrimination: Learning to respond only to specific stimuli.

Classical Conditioning

Classical conditioning is a type of learning first described by Ivan Pavlov, where a neutral stimulus becomes associated with a meaningful stimulus, eliciting a conditioned response.

• Key Terms:

  • Unconditioned Stimulus (US): Naturally elicits a response (e.g., food).

  • Unconditioned Response (UR): Natural reaction to the US (e.g., salivation).

  • Neutral Stimulus (NS): Does not elicit the response before conditioning (e.g., bell).

  • Conditioned Stimulus (CS): Previously neutral, now elicits response after association (e.g., bell after pairing with food).

  • Conditioned Response (CR): Learned response to the CS (e.g., salivation to bell).

• Pavlov's Experiment: Pavlov paired the sound of a bell (NS) with food (US), leading dogs to salivate (UR). After repeated pairings, the bell alone (now CS) caused salivation (CR).

Example: If a dog hears a bell every time it is fed, eventually the bell alone will make the dog salivate.

Operant Conditioning (B.F. Skinner)

Operant conditioning involves learning through the consequences of behavior, such as rewards (reinforcement) and punishments.

• Positive Reinforcement: Adding a desirable stimulus to increase behavior.

• Negative Reinforcement: Removing an aversive stimulus to increase behavior.

• Punishment: Applying or removing a stimulus to decrease behavior.

• Schedules of Reinforcement:

  • Continuous Reinforcement: Every response is reinforced.

  • Intermittent Reinforcement: Only some responses are reinforced.

• Shaping: Gradually guiding behavior toward a desired outcome through successive approximations.

Example: Giving a child praise (positive reinforcement) for completing homework increases the likelihood of future homework completion.

Applications and Additional Concepts

• Counterconditioning: Replacing an unwanted response with a desired one.

• Biological Constraints: Some behaviors are easier to condition due to biological predispositions.

• Observational Learning: Learning by watching others (not covered in detail here, but relevant to learning theories).

Review and Study Tips

• Review key chapters and terms for exams.

• Practice identifying examples of classical and operant conditioning.

• Be able to explain the process of conditioning and identify US, UR, NS, CS, and CR in scenarios.

• Understand the difference between reinforcement and punishment, and their effects on behavior.

Table: Comparison of Classical and Operant Conditioning

Feature	Classical Conditioning	Operant Conditioning
Type of Learning	Association between stimuli	Association between behavior and consequence
Key Figures	Ivan Pavlov	B.F. Skinner
Main Components	US, UR, NS, CS, CR	Reinforcement, Punishment, Shaping
Example	Dog salivates to bell	Child receives praise for homework

Key Equations and Terms

• Acquisition: The initial stage of learning when a response is first established.

• Extinction: The diminishing of a conditioned response when the US no longer follows the CS.

• Spontaneous Recovery: The reappearance of a weakened CR after a pause.
