Conditioning, Insight Learning, and Social Learning

Overview of Learning Types

  • Classical Conditioning

  • Instrumental Conditioning

  • Insight Learning

  • Social Learning

Classical Conditioning

Definition

  • Classical conditioning is a learning process in which a neutral stimulus becomes associated with an unconditioned stimulus to elicit a conditioned response.

Key Concepts

  1. Unconditioned Stimulus (UCS): Stimulus that naturally and automatically triggers a response without prior learning.

  2. Unconditioned Response (UCR): The unlearned, naturally occurring response to the UCS.

  3. Conditioned Stimulus (CS): Originally irrelevant stimulus that, after association with an UCS, comes to trigger a conditioned response.

  4. Conditioned Response (CR): Learned response to a previously neutral stimulus.

Ivan Pavlov's Contributions (1849-1936)

  • Conducted experiments demonstrating classical conditioning using dogs.

Conditioning Process Stages

  1. Before Conditioning:

    • UCS (Food) → UCR (Salivation)

    • CS (Whistle) does not produce a response before conditioning.

  2. During Conditioning:

    • CS (Whistle) + UCS (Food) → UCR (Salivation)

  3. After Conditioning:

    • CS (Whistle) → CR (Salivation)

Mechanism of Classical Conditioning

  • Learning through Association: A relevant stimulus (UCS) produces a reflexive response (UCR). Two stimuli (the relevant and an irrelevant) are linked to produce a new learned response.

Higher-Order Conditioning

  • Definition: A second conditioned stimulus (second-order stimulus) is paired with a first conditioned stimulus.

  • Example: An electric can opener (CS) paired with a squeaky cabinet door leads to a conditioned response of salivation (CR).

Key Phenomena

  1. Conditioned Aversion: One trial learning; having a strong association after just one exposure. Commonly seen in food aversion.

  2. Conditioned Emotional Response: Examples include phobias.

    • John B. Watson's Little Albert Experiment: Albert developed a fear of similar stimuli (e.g., white rat associated with loud sounds).

Additional Classical Conditioning Concepts

  • Generalization: Responding similarly to stimuli resembling the CS.

  • Discrimination: Learning to respond only to the original CS.

  • Extinction: Weakening and disappearance of the CR when the CS is presented without the UCS.

  • Spontaneous Recovery: Reemergence of a previously extinguished CR.

Operant Conditioning (Instrumental Conditioning)

Definition

  • This type of learning involves modifying behavior based on the consequences that follow it.

Key Theorist: Edward Thorndike

  • Law of Effect: The likelihood of a behavior being repeated depends on its effect on the environment and the organism.

Skinner's Contribution

  • Operant Conditioning: Learning to operate on the environment to produce consequences.

  • Skinner Box: Used to observe the behavior of animals. Contained reinforcers and punishers.

Key Concepts of Operant Conditioning

  1. Reinforcement: Increases the probability of a behavior.

    • Positive Reinforcement: A pleasant stimulus is added following a behavior.

    • Negative Reinforcement: An unpleasant stimulus is removed following a behavior.

  2. Punishment: Decreases the probability of a behavior occurring.

Shaping

  • Definition: The process of reinforcing successively closer approximations to a desired terminal behavior.

  • Essential questions for creating a shaping plan:

    1. What behavior will you teach?

    2. What animal will be used?

    3. What are the required steps?

    4. What rewards will be used?

Learned Helplessness

  • Definition: Behavior exhibited by animals or humans when they experience uncontrollable aversive situations.

  • Symptoms include depression, anxiety, and stress.

  • Leads to negative behavioral outcomes and social issues.

Reinforcement and Its Schedules

Types of Reinforcement

  • Continuous Reinforcement: Constant delivery of reinforcement; can lead to rapid extinction.

  • Intermittent Reinforcement: Not every response is reinforced, can be more effective than continuous.

Schedules of Reinforcement

  1. Fixed Interval Schedule: Reinforcement occurs after a set amount of time.

  2. Variable Interval Schedule: Reinforcement occurs after varying amounts of time.

  3. Fixed Ratio Schedule: Reinforcement occurs after a fixed number of responses.

  4. Variable Ratio Schedule: Reinforcement occurs after a varied number of responses.

Comparison of Responses Under Different Schedules

  • Figure Review: Understanding the pattern of responses over time under various reinforcement schedules.

Key Questions

  • Discuss which reinforcement schedule is best and justify with reasoning.

Insight Learning

Definition

  • A trial-and-error process where a stimulus-response association is formed. It involves a sudden realization of a solution.

Characteristics of Insight Learning

  • Change in perception.

  • Sudden understanding of the problem.

  • Associated with higher cognitive processes; better in adults than children, and influenced by prior experience and perceptual organization.

Social Learning Theory

Overview

  • Albert Bandura: Emphasized observational learning.

  • Bobo Doll Experiment (1961): Demonstrated children learn behaviors through observation of adults.

Implications

  • Observational learning suggests that behaviors can be learned vicariously by watching others, modifying possibilities in social learning settings.
