Learning

  • Definition: A relatively permanent change in behavior due to experience.

Classical Conditioning (CC)

  • Overview: Developed by Ivan Pavlov in the early 1900s.

  • Key Concepts:

    • Stimulus: Any event or situation that evokes a response.

    • CC Definition: A neutral stimulus elicits a response after being paired with a naturally occurring stimulus that brings about that response.

    • Key Aspect: Learning involves making associations between two stimuli.

    • Nature of Response: Responses are involuntary or automatic.

Process of Classical Conditioning

  • Neutral Stimulus (NS): Initially does not evoke a response.

  • Unconditioned Stimulus (US): Naturally brings about a response.

    • Example: Food (US) leads to salivation (Unconditioned Response, UR).

  • Conditioning Process:

    • During conditioning, the NS is paired with the US.

    • After conditioning, the NS becomes the Conditioned Stimulus (CS) and elicits a Conditioned Response (CR).

Example Illustration:

  • Before Conditioning: CS (Tone of C) + US (Food) = No salivation.

  • During Conditioning: US (Food) causes UR (Salivation).

  • After Conditioning: CS (Tone of C) causes CR (Salivation).

Types of Conditioned Responses

  • Physiological Responses: E.g., salivation, change in heart rate.

  • Muscular Reflexes: E.g., involuntary muscle movement, flinching.

  • Emotions: E.g., mood states like happiness and anger.

  • Attitudes: Automatic judgments of things (likes and dislikes).

Emotional Conditioning

  • Example: John Watson's study with Little Albert shows emotional responses can be conditioned.

Application of Classical Conditioning in Advertising

  • Process:

    • Neutral Stimulus (Rx product) paired with Unconditioned Stimulus (people having fun) creates a positive response.

    • Outcome: Consumers associate Rx products with happiness.

Generalization and Discrimination

  • Generalization: Stimuli similar to CS can elicit CR.

    • Example: Pavlov’s experiment with dogs salivating to various body stimulations.

  • Discrimination: The ability to differentiate between CS and other stimuli; only similar but distinct stimuli will not elicit CR.

Extinction and Spontaneous Recovery

  • Extinction: The CR diminishes over time without the US present.

  • Spontaneous Recovery: The CR can re-emerge after a period of rest following extinction.

Graphical Representation of Extinction:

  • Acquisition (initial learning), Extinction (CR decreases), followed by Spontaneous Recovery (reemergence of CR).

Operant Conditioning

  • Overview: Learning an association between a behavior and its consequences.

  • Response Nature: Voluntary behaviors.

Law of Effect (Thorndike)

  • Principle: Behaviors followed by favorable consequences are likely to recur, while those with unfavorable consequences are less likely to recur.

Reinforcement

  • Types:

    • Positive Reinforcement: Adding a pleasant stimulus; e.g., getting food for pressing a bar.

    • Negative Reinforcement: Removing an unpleasant stimulus; e.g., pressing a bar to stop a loud noise.

Punishment

  • Types:

    • Positive Punishment: Adding an unpleasant stimulus; e.g., a reprimand for bad behavior.

    • Negative Punishment: Removing a pleasant stimulus; e.g., taking away privileges.

Comparing Reinforcement and Punishment

  • Reinforcement increases behavior,

  • Punishment decreases behavior.

Examples of Reinforcement and Punishment in Action

  • Positive Reinforcement: Getting a high five after scoring; A dog gets petted for coming when called.

  • Negative Reinforcement: Taking painkillers to end pain; buckling a seatbelt to stop a warning sound.

  • Positive Punishment: Spraying water on a barking dog; receiving a traffic ticket.

  • Negative Punishment: Withdrawing driving privileges from a misbehaving teen.

Practical Examples of Reinforcement & Punishment

  • Situational stimuli applying to personal experiences, demonstrating the principles of operant conditioning.

Factors Influencing Reinforcement Effectiveness

  • Magnitude: Size of the reinforcer.

  • Immediacy: Time between behavior and reinforcer.

  • Learner's Motivation: Individual learner’s readiness.

Classical vs. Operant Conditioning Summary

Aspect

Classical Conditioning

Operant Conditioning

Learning Type

Association between stimuli we don't control.

Association between behavior and its consequences.

Nature of Response

Involuntary, automatic.

Voluntary, operates on the environment.

Key Component

CS announces US.

Behavior is linked to consequences (reinforce/punisher)

Extinction

CR decreases when CS is presented alone.; reappearance of CR after a rest period

Responding decreases when reinforcement stops; reappearance after a rest period

Discrimination

Learning to distinguish between CS and other stimuli.

Learning that some responses are reinforced while others are not.

Cognitive Processes in Learning

  • Latent Learning: Learning that is not evident until there’s a reason to demonstrate it.

  • Cognitive Maps: Mental representations of spatial arrangements, like navigating a maze.

Observational Learning (Modeling)

  • Definition: Learning by observing others.

  • Example: Children mimic behaviors seen in models; influences include prosocial and antisocial behaviors.

    • Supported by Albert Bandura's studies, especially regarding the depiction of violence in media.

Example

Classical Conditioning

NS paired with US

NS becomes CS that elicits CR

Bell elicits a response in a dog.

Operant Conditioning

Behavior followed by reinforcement or punishment

Behavior frequency increases or decreases based on consequence

Rat presses a bar for food.

Observational Learning

Observer looks to model behavior

Observer learns behaviors to replicate on command

Children exhibit aggression after watching violent TV.
