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 |
