Behaviourism — Study Notes for CG TET
Overview
Behaviourism is one of the most foundational learning theories you will encounter in the Child Development and Pedagogy section of CG TET. It explains learning as a change in observable behaviour caused by external stimuli, without focusing on internal mental processes. For a teacher, understanding behaviourism means knowing how to shape student behaviour through reinforcement, punishment and repetition.
Mastering Pavlov, Thorndike and Skinner is non-negotiable for scoring well in this section.
The core idea is simple: behaviour that is rewarded tends to repeat; behaviour that is punished or ignored tends to disappear. This "stimulus-response" framework forms the backbone of behaviourist pedagogy and remains relevant in everyday classroom management.
Key Concepts
- Learning = Change in behaviour: Behaviourists define learning only through observable, measurable changes — not internal thoughts or feelings.
- Stimulus-Response (S-R) Bond: All learning involves forming connections between a stimulus (trigger) and a response (behaviour).
- Classical Conditioning (Pavlov): Learning occurs when a neutral stimulus becomes associated with an unconditioned stimulus, eventually producing a conditioned response automatically.
- Connectionism (Thorndike): Learning is trial-and-error; correct responses are "stamped in" through satisfaction, while incorrect ones are "stamped out."
- Operant Conditioning (Skinner): Behaviour is controlled by its consequences — reinforcement increases behaviour, punishment decreases it.
- Role of Environment: Behaviourists believe the environment (not heredity or internal motivation) is the primary driver of learning.
- Teacher as Controller: The teacher designs the environment, provides stimuli and manages consequences to shape student behaviour.
Key Facts — The Three Theorists
Ivan Pavlov (1849–1936) — Classical Conditioning
| Term | Meaning |
|---|---|
| Unconditioned Stimulus (UCS) | Naturally triggers a response (e.g., food) |
| Unconditioned Response (UCR) | Natural response to UCS (e.g., salivation) |
| Neutral Stimulus (NS) | Initially produces no response (e.g., bell) |
| Conditioned Stimulus (CS) | After pairing, triggers learned response (bell after training) |
| Conditioned Response (CR) | Learned response to CS (salivation to bell) |
Pavlov's Dog Experiment: Bell (NS) + Food (UCS) → Salivation (UCR). After repeated pairing, Bell alone (CS) → Salivation (CR).
Edward Thorndike (1874–1949) — Connectionism / Trial-and-Error
Puzzle Box Experiment: A hungry cat in a box learned to press a lever to escape and get food — through random trial-and-error, not insight.
Three Laws of Learning:
- Law of Readiness — Learning is effective when the learner is physically and mentally prepared.
- Law of Exercise — Connections strengthen with practice (use) and weaken without practice (disuse).
- Law of Effect — Responses followed by satisfaction are strengthened; those followed by discomfort are weakened.
B.F. Skinner (1904–1990) — Operant Conditioning
Skinner Box Experiment: A rat pressed a lever accidentally; food appeared (reinforcement). The rat repeated lever-pressing.
| Concept | Definition | Effect on Behaviour |
|---|---|---|
| Positive Reinforcement | Adding a pleasant stimulus | Increases behaviour (praise after correct answer) |
| Negative Reinforcement | Removing an unpleasant stimulus | Increases behaviour (excusing homework for good work) |
| Positive Punishment | Adding an unpleasant stimulus | Decreases behaviour (extra work for misbehaviour) |
| Negative Punishment | Removing a pleasant stimulus | Decreases behaviour (no recess for fighting) |
Reinforcement Schedules: Continuous (every time), Fixed Ratio, Variable Ratio, Fixed Interval, Variable Interval — variable schedules produce most persistent behaviour.
Worked Examples
Example 1 — Identifying Classical Conditioning
Question: A child feels anxious whenever she sees her Mathematics teacher because the teacher once scolded her harshly. Identify the CS, UCS, CR and UCR.
Solution:
- UCS = Harsh scolding (naturally causes fear)
- UCR = Fear/anxiety (natural response to scolding)
- NS → CS = Mathematics teacher (initially neutral, now triggers fear)
- CR = Anxiety on seeing the teacher
This is classical conditioning — the teacher became associated with the unpleasant experience.
Example 2 — Applying Thorndike's Law of Effect
Question: A student solves a problem correctly and the teacher smiles and says "Excellent!" The student attempts more problems enthusiastically. Which law explains this?
Solution:
- The praise (satisfying consequence) followed the correct response.
- According to the Law of Effect, responses followed by satisfaction are strengthened.
- Hence, the student repeats the behaviour (attempting more problems).
Example 3 — Distinguishing Reinforcement Types
Question: A teacher stops giving a student detention when he submits homework on time. What type of operant conditioning is this?
Solution:
- Detention (unpleasant stimulus) is being removed.
- The removal is contingent on desired behaviour (submitting homework).
- This is Negative Reinforcement — removing something unpleasant to increase a behaviour.
Note: Negative reinforcement is NOT punishment. Both positive and negative reinforcement increase behaviour.
Common Mistakes
| Wrong Thinking | Correct Understanding |
|---|---|
| "Negative reinforcement means punishment." | Negative reinforcement removes an unpleasant stimulus to increase behaviour; punishment decreases behaviour. |
| "Pavlov's conditioning explains all classroom learning." | Classical conditioning explains involuntary/emotional responses (fear, anxiety). Voluntary learning (answering questions) is better explained by operant conditioning. |
| "Thorndike's Law of Exercise means more practice always helps." | Thorndike later revised this — practice helps only when followed by feedback/reinforcement. Mindless repetition without satisfaction is ineffective. |
| "Skinner and Pavlov are the same — both use stimulus-response." | Pavlov deals with involuntary reflexes triggered by stimuli; Skinner deals with voluntary behaviours shaped by consequences. |
| "Behaviourism explains internal motivation and creativity." | Behaviourism deliberately ignores internal states. It cannot explain insight, curiosity or intrinsic motivation — a key limitation. |
Quick Reference
- Pavlov → Classical Conditioning → Dog + Bell → Involuntary response
- Thorndike → Trial-and-Error → Cat + Puzzle Box → Law of Effect
- Skinner → Operant Conditioning → Rat + Lever → Reinforcement/Punishment
- Reinforcement = Behaviour increases; Punishment = Behaviour decreases
- Positive = Adding stimulus; Negative = Removing stimulus
- Educational implication: Use praise, rewards and immediate feedback to strengthen desired learning behaviours
