Behaviourism: Pavlov, Skinner and Thorndike
Overview
Behaviourism is one of the most frequently tested learning theories in TS TET Child Development and Pedagogy. It views learning as a change in observable behaviour resulting from environmental stimuli, rather than internal mental processes. For the exam, you must understand three foundational theorists: Pavlov (classical conditioning), Thorndike (connectionism/trial-and-error), and Skinner (operant conditioning).
This topic matters because behaviourist principles form the backbone of classroom practices like reward systems, punishment protocols, drill-and-practice methods, and habit formation. Questions typically ask you to identify the correct theorist for a given experiment, distinguish between classical and operant conditioning, or apply these principles to classroom situations. Master the key experiments, laws, and terminology—these are direct question sources.
Key Concepts
- Behaviourism's core assumption: Learning is a stimulus-response (S-R) connection. Only observable, measurable behaviour counts—not thoughts, feelings, or mental states.
- Classical Conditioning (Pavlov): Learning occurs when a neutral stimulus becomes associated with an unconditioned stimulus, eventually producing a conditioned response. The learner is passive.
- Connectionism (Thorndike): Learning is trial-and-error. Successful responses get "stamped in" through satisfaction; unsuccessful ones get "stamped out." Introduced the S-R bond concept.
- Operant Conditioning (Skinner): Learning occurs through consequences of voluntary behaviour. Reinforcement strengthens behaviour; punishment weakens it. The learner is active.
- Reinforcement vs Punishment: Reinforcement (positive or negative) increases behaviour frequency. Punishment decreases behaviour frequency.
- Role of environment: All three theorists emphasise that the external environment shapes behaviour—heredity and internal states are secondary.
- Classroom implication: Behaviourism supports drill, repetition, immediate feedback, reward charts, token economies, and structured teaching.
Key Facts and Definitions
| Term | Meaning |
|---|---|
| Unconditioned Stimulus (UCS) | Naturally triggers a response (e.g., food causing salivation) |
| Unconditioned Response (UCR) | Natural, unlearned reaction to UCS |
| Conditioned Stimulus (CS) | Previously neutral stimulus that, after pairing, triggers response |
| Conditioned Response (CR) | Learned response to the conditioned stimulus |
| Positive Reinforcement | Adding a pleasant stimulus to increase behaviour |
| Negative Reinforcement | Removing an unpleasant stimulus to increase behaviour |
| Positive Punishment | Adding an unpleasant stimulus to decrease behaviour |
| Negative Punishment | Removing a pleasant stimulus to decrease behaviour |
| Law of Effect | Responses followed by satisfaction are strengthened |
| Law of Exercise | Repeated practice strengthens S-R bonds |
| Law of Readiness | Learning is effective when the learner is prepared |
Pavlov's Experiment: Dog, bell, food. Bell (neutral) paired with food (UCS) repeatedly. Eventually, bell alone (now CS) causes salivation (CR).
Thorndike's Experiment: Cat in puzzle box. Through random movements (trial-and-error), cat escapes and gets food. Escape time decreases with trials.
Skinner's Experiment: Rat/pigeon in Skinner Box. Pressing lever delivers food (reinforcement). Behaviour frequency increases.
Worked Examples
Example 1: Identifying Conditioning Type
Question: A child studies hard because her teacher gives her gold stars. Which type of conditioning is this?
Solution:
- Step 1: Is the behaviour voluntary? Yes—studying is a choice.
- Step 2: Is something being added or removed? Gold stars are added.
- Step 3: Does the behaviour increase? Yes.
- Answer: Operant conditioning with positive reinforcement (Skinner).
Example 2: Applying Thorndike's Laws
Question: A teacher makes students practice multiplication tables daily. Which law of Thorndike supports this?
Solution:
- Step 1: Daily practice means repetition and drill.
- Step 2: Thorndike's Law of Exercise states that repeated use strengthens S-R connections.
- Answer: Law of Exercise.
Example 3: Classical Conditioning in Classroom
Question: Students feel anxious whenever they see the math teacher because he often scolds them during math class. Identify the components.
Solution:
- UCS: Scolding (naturally causes anxiety)
- UCR: Anxiety (natural response to scolding)
- CS: Math teacher (previously neutral, now associated with scolding)
- CR: Anxiety upon seeing the teacher
- Answer: Classical conditioning (Pavlov). The teacher has become a conditioned stimulus.
Common Mistakes
- Confusing negative reinforcement with punishment → Negative reinforcement removes something unpleasant to increase behaviour (e.g., excusing homework for good behaviour). Punishment decreases behaviour. Remember: reinforcement always increases, punishment always decreases.
- Mixing up Pavlov and Skinner → Pavlov deals with involuntary/reflexive responses (salivation, fear). Skinner deals with voluntary behaviour (pressing lever, studying). Ask: "Is the response automatic or chosen?"
- Forgetting Thorndike's position → Students often skip Thorndike or merge him with Skinner. Thorndike came before Skinner and focused on trial-and-error and the Law of Effect. He is the bridge between Pavlov and Skinner.
- Thinking behaviourism explains all learning → Behaviourism ignores cognition, insight, and social learning. Exam questions may ask for limitations—be ready to note that it cannot explain complex problem-solving or creativity.
- Assuming negative means bad → "Negative" in reinforcement/punishment means removal, not something harmful. Negative reinforcement is still reinforcement (increases behaviour).
Quick Reference
- Pavlov = Classical Conditioning = Involuntary response = S-S association (stimulus-stimulus)
- Thorndike = Connectionism = Trial-and-error = Law of Effect, Exercise, Readiness
- Skinner = Operant Conditioning = Voluntary behaviour = Reinforcement and Punishment
- Reinforcement → Behaviour increases | Punishment → Behaviour decreases
- Positive = Add something | Negative = Remove something
- Classroom uses: Rewards, token economy, drill-practice, immediate feedback, habit formation
