Chapter 10: Learning Psychology 102

1. Basic Learning Concepts

  • Learning: Acquisition of new, relatively enduring information or behaviors through experience.

  • Associative Learning: Learning that certain events occur together, which can involve two stimuli (Classical Conditioning) or a response and its consequences (Operant Conditioning).

2. Fundamental Principles of Classical Conditioning

  • Stimulus: Event or situation that evokes a response.

  • Conditioning: Process of connecting stimuli with behaviors.

    • Two main forms:

      • Classical Conditioning

      • Operant Conditioning

      • Observational Learning: Acquisition through observation and language.

3. Classical Conditioning: Key Components

  • Examples of Classical Conditioning:

    • Stimulus 1: Thunder

    • Stimulus 2: Lightning

    • Response: Startled reaction (wincing)

  • Process Overview:

    • Startled by thunder, anticipate it due to previous lightning experience leading to conditioned responses.

4. Ivan Pavlov's Contributions

  • Pavlov's experiments demonstrated classical conditioning:

    • Example: Food (Unconditioned Stimulus) causing salivation (Unconditioned Response).

    • A bell (Neutral Stimulus) is linked with food, eventually causing salivation alone (Conditioned Response).

5. Classical Conditioning Stages

Before Conditioning:

  • Unconditioned Stimulus (US): Food

  • Unconditioned Response (UR): Salivation

  • Neutral Stimulus (NS): Whistle (no salivation)

During Conditioning:

  • Associating: Whistle + Food

After Conditioning:

  • Conditioned Stimulus (CS): Whistle

  • Conditioned Response (CR): Salivation

6. Definitions of Terms

  • Neutral Stimulus (NS): Elicits no response before conditioning.

  • Unconditioned Response (UR): Unlearned response to an unconditioned stimulus (like salivation).

  • Unconditioned Stimulus (US): Triggers unconditioned response naturally (such as food).

  • Conditioned Response (CR): Learned response to a previously neutral (now conditioned) stimulus.

  • Conditioned Stimulus (CS): Initially irrelevant stimulus that, after association with unconditioned stimulus, triggers a conditioned response.

7. Conditioning Processes

  • Acquisition: Initial learning stage linking NS and US.

  • Extinction: Diminishing of CR when US does not follow CS.

  • Spontaneous Recovery: Reappearance of extinguished CR after a pause.

  • Generalization: Stimuli similar to CS elicit similar responses.

  • Discrimination: Ability to distinguish between CS and similar stimuli not signaling US.

8. Higher-Order Conditioning

  • A strong CS paired with a neutral (now NS) could form a new CS (e.g., advertisement techniques).

  • Preparedness: Organisms are evolutionarily prepared to learn certain associations more easily.

9. Applications of Classical Conditioning

  • Influences on human health: drug cravings, emotional behaviors, therapy applications.

10. Operant Conditioning

  • B. F. Skinner: Influential figure in behaviorism; expanded on Thorndike’s law of effect.

  • Operant Conditioning: Strengthening behavior followed by reinforcer, diminishing when followed by punisher.

11. Reinforcements

Positive Reinforcement:

  • Strengthens response by presenting pleasant stimulus.

Negative Reinforcement:

  • Strengthens response by removing unpleasant stimulus.

12. Types of Reinforcers

  • Primary Reinforcer: Innately satisfies biological needs.

  • Conditioned Reinforcer: Gains power through association with primary reinforcer.

13. Reinforcement Schedules

  • Continuous Reinforcement: Reinforcement every time behavior occurs.

  • Partial Reinforcement: Only some behaviors are reinforced.

    • Types:

      • Fixed-ratio: After a fixed number of responses.

      • Variable-ratio: After an unpredictable number of responses.

      • Fixed-interval: After a fixed amount of time.

      • Variable-interval: After an average amount of time.

14. Punishment

  • Positive Punishment: Presenting a negative consequence after undesired behavior.

  • Negative Punishment: Removing a desired stimulus after an undesired behavior.

  • Major drawbacks include teaching fear and not replacing unwanted behavior.

15. Shaping Behavior

  • Shaping: Gradually guiding behavior towards desired target through reinforcement.

  • Successive Approximations: Rewarding behaviors closer to the desired one.

16. Learning and Cognition

  • Cognitive Influences: Expectation of a CS signaling US develops.

  • Learning occurs through predictions and expectations.

17. Observational Learning

  • Learning by observing and imitating others' behaviors.

  • Modeling: Imitating specific behaviors.

  • Social impacts: prosocial vs antisocial behaviors seen in children.

    • Example: Bandura's Bobo Doll experiment showcasing aggression and learning.

18. Implications of Observational Learning

  • Promoting helpful behaviors and communications in learning environments.

  • Antisocial effects of observing negative behaviors such as aggression and deceit.
