Learning: Classical, Operant, and Observational Conditioning – Chapter 5 Study Guide

Learning: An Overview

Definition of Learning

Learning is a relatively permanent change in behavior or knowledge that results from experience. It is a fundamental psychological process that enables organisms to adapt to their environment.

• Key Point: Learning involves acquiring new behaviors or modifying existing ones through experience.

• Example: A child learns to ride a bicycle after repeated practice.

Classical Conditioning

Conditioned Behaviors in Classical Conditioning

Classical conditioning typically conditions involuntary, reflexive behaviors such as salivation, fear responses, or emotional reactions.

• Key Point: Behaviors conditioned are automatic responses to stimuli.

• Example: Salivating when smelling food.

Pavlov’s Original Experiment

Pavlov demonstrated classical conditioning by pairing a neutral stimulus (bell) with an unconditioned stimulus (food) to elicit a conditioned response (salivation).

• Unconditioned Stimulus (US): Food

• Unconditioned Response (UR): Salivation to food

• Conditioned Stimulus (CS): Bell

• Conditioned Response (CR): Salivation to bell

Association Learned in Classical Conditioning

The association learned is between the conditioned stimulus (CS) and the unconditioned stimulus (US), so that the CS alone elicits the response.

Example of Classical Conditioning in Everyday Life

• US: Dentist drill sound

• UR: Anxiety or fear

• CS: Sight of dentist's office

• CR: Anxiety upon entering dentist's office

Conditioned Emotional Response

A conditioned emotional response is an emotional reaction (such as fear or happiness) that is learned through classical conditioning.

• Example: Fear of dogs after being bitten as a child.

Wolpe’s Desensitization Therapy

Wolpe developed systematic desensitization, a behavioral therapy technique used to reduce phobic responses by gradually exposing individuals to the feared stimulus while teaching relaxation techniques.

Preparedness and Conditioned Taste Aversion

Preparedness refers to the biological predisposition to learn certain associations more easily than others. Conditioned taste aversion occurs when an organism associates the taste of a particular food with illness, even after a single pairing.

• Example: Avoiding a food after getting sick from it once.

Extinction, Spontaneous Recovery, Generalization, and Discrimination in Classical Conditioning

• Extinction: The weakening of the conditioned response when the conditioned stimulus is repeatedly presented without the unconditioned stimulus.

• Spontaneous Recovery: The reappearance of a previously extinguished conditioned response after a rest period.

• Generalization: Responding to stimuli similar to the conditioned stimulus.

• Discrimination: Learning to respond only to the specific conditioned stimulus and not to similar stimuli.

• Demonstration: Extinction: Ringing the bell without presenting food; Spontaneous recovery: After a break, the dog salivates to the bell again; Generalization: Dog salivates to a chime; Discrimination: Dog only salivates to the original bell sound.

Operant Conditioning

Conditioned Behaviors in Operant Conditioning

Operant conditioning conditions voluntary behaviors, such as pressing a lever, studying, or working for rewards.

Skinner’s Demonstration of Operant Conditioning

Skinner used a "Skinner box" where animals learned to press a lever to receive food, demonstrating how behavior is shaped by consequences.

Shaping

Shaping is the process of reinforcing successive approximations of a desired behavior until the target behavior is achieved.

• Example: Teaching a dog to roll over by rewarding each step toward the full behavior.

Association Learned in Operant Conditioning

The association is between a behavior and its consequence (reinforcement or punishment).

Positive and Negative Reinforcement

• Positive Reinforcement: Adding a desirable stimulus to increase a behavior (e.g., giving praise for homework).

• Negative Reinforcement: Removing an aversive stimulus to increase a behavior (e.g., turning off a loud alarm when you get up).

Examples of Operant Conditioning in Everyday Life

• Getting paid for work (positive reinforcement)

• Taking painkillers to relieve a headache (negative reinforcement)

Problems with Using Punishment

• Punishment can lead to fear, aggression, and avoidance rather than learning the desired behavior.

• It does not teach alternative appropriate behaviors.

Superstitious Behavior (Skinner)

Skinner explained superstitious behavior as accidental reinforcement of a behavior that is not actually related to the outcome.

• Example: Wearing a "lucky" shirt because you won a game while wearing it.

Learned Helplessness (Seligman)

Seligman demonstrated learned helplessness in dogs by exposing them to unavoidable shocks, after which they failed to escape even when escape was possible.

• Example: A student stops trying after repeated failures, believing success is impossible.

Applied Behavior Analysis (ABA)

ABA is the application of operant conditioning principles to change socially significant behaviors, often used in therapy for autism spectrum disorders.

Schedules of Reinforcement

Reinforcement schedules determine how and when behaviors are reinforced.

Schedule	Definition	Example
Fixed Ratio	Reinforcement after a set number of responses	Getting a bonus for every 10 sales
Variable Ratio	Reinforcement after a varying number of responses	Slot machine payouts
Fixed Interval	Reinforcement after a set period of time	Weekly paycheck
Variable Interval	Reinforcement after varying time intervals	Checking for a random email response

Primary and Secondary Reinforcers

• Primary Reinforcer: Naturally reinforcing (e.g., food, water)

• Secondary Reinforcer: Acquires reinforcing value through association (e.g., money, grades)

Extinction, Spontaneous Recovery, Generalization, and Discrimination in Operant Conditioning

• Extinction: Behavior decreases when reinforcement is withheld.

• Spontaneous Recovery: Behavior reappears after a rest period.

• Generalization: Behavior occurs in response to similar stimuli.

• Discrimination: Behavior occurs only in response to specific stimuli.

• Demonstration: Extinction: Stop rewarding lever presses; Spontaneous recovery: Animal presses lever after a break; Generalization: Animal presses similar levers; Discrimination: Animal only presses the original lever.

Stimulus Control

Stimulus control occurs when a behavior is performed only in the presence of a specific stimulus.

• Example: Only answering the phone when it rings.

Cognitive and Observational Learning

Latent Learning and Cognitive Maps (Tolman)

Tolman showed that rats could learn the layout of a maze without reinforcement, demonstrating the concept of cognitive maps and latent learning.

Insight Learning (Kohler)

Kohler observed apes solving problems by sudden insight, rather than trial-and-error learning.

• Example: An ape stacking boxes to reach a banana.

Learning Set (Harlow)

A "learning set" refers to the ability to learn how to learn, improving problem-solving efficiency through experience with similar tasks.

Observational Learning (Bandura’s Bobo Doll Experiment)

Bandura demonstrated that children imitate aggressive behavior after observing adults act aggressively toward a Bobo doll.

• Key Point: Learning can occur through observation, not just direct experience.

Requirements for Imitation

• Attention

• Retention

• Reproduction

• Motivation

Vicarious Reinforcement and Self-Regulation

• Vicarious Reinforcement: Observing someone else being rewarded increases the likelihood of imitating their behavior.

• Self-Regulation: The ability to control one's own behavior through self-monitoring and self-reinforcement.
