Learning Theories: Classical, Operant & Observational Learning
1. What is Learning?
In psychology, learning is defined as any relatively permanent change in behavior, potential, or knowledge that occurs as a result of experience, practice, or observation.
It excludes temporary behavioral changes caused by physical fatigue, maturation, drugs, or illness.
The Three Great Pillars of Learning Theory
1. Classical Conditioning (Ivan Pavlov)
Learning through stimulus-stimulus association. An involuntary biological response becomes linked to a previously neutral trigger.
2. Operant Conditioning (B.F. Skinner)
Learning through consequences. Voluntary behavior is shaped, strengthened, or weakened by reinforcement and punishment.
3. Observational Learning (Albert Bandura)
Social cognitive learning. Acquiring behaviors vicariously by observing, encoding, and imitating the actions of social models.
2. Pavlov’s Classical Conditioning (S-S Learning)
Discovered accidentally by Russian physiologist Ivan Pavlov while studying canine digestive secretions:
Key Conditioning Elements:
- Unconditioned Stimulus (UCS): A natural trigger that automatically produces a reflex response without prior learning (e.g., Meat Powder / Food).
- Unconditioned Response (UCR): The automatic, unlearned physiological reflex to the UCS (e.g., Salivation to meat powder).
- Conditioned Stimulus (CS): A previously neutral stimulus that, after repeated association with the UCS, triggers a conditioned response (e.g., Bell Sound).
- Conditioned Response (CR): The learned reaction to the conditioned stimulus (e.g., Salivation to the sound of the bell alone).
Pavlovian Conditioning Process
01
Before Training
Food (UCS) → Salivation (UCR); Bell (Neutral) → No Salivation.
➔
02
During Training
Bell (CS) paired repeatedly with Food (UCS) in close succession.
➔
03
After Conditioning
Bell (CS) alone triggers Salivation (CR).
3. Skinner’s Operant Conditioning (R-S Learning)
Formulated by B.F. Skinner based on Thorndike’s Law of Effect, operant conditioning states that behavior is determined by its consequences.
Reinforcement vs Punishment:
- Positive Reinforcement (+R): Adding a desirable rewarding stimulus (praise, money, high grades) to increase the likelihood of a target behavior.
- Negative Reinforcement (-R): Removing an annoying/aversive stimulus (turning off an irritating alarm or taking an aspirin to stop a headache) to increase behavior.
- Positive Punishment (+P): Presenting an unpleasant stimulus (scolding, penalty fine) to decrease an unwanted behavior.
- Negative Punishment (-P): Removing a pleasant privilege (grounding a teen, revoking a phone) to decrease behavior.
4. Bandura’s Observational Learning (Social Cognitive Theory)
Albert Bandura demonstrated through his famous Bobo Doll Experiment (1961) that children learn aggressive behaviors simply by watching adult models, without direct reinforcement.
Bandura's Four Core Modeling Processes
01
Attention
The observer must actively notice and pay focus to the model's behavior.
➔
02
Retention
The observed behavior must be mentally coded and stored in memory as imagery or verbal symbols.
➔
03
Reproduction
The physical and motor capability to accurately perform the stored mental representation.
➔
04
Motivation
Having a compelling reason (vicarious reinforcement, personal incentive) to actually display the learned act.
