Overview
Edward L. Thorndike proposed that learning is a gradual strengthening of stimulus–response connections when responses produce satisfying results—connectionism.

Puzzle box
Hungry cats escaped a box by pulling a loop; escape times fell gradually, suggesting incremental learning rather than insight.
Three laws
| Law | Meaning |
|---|---|
| Effect | Satisfying consequences strengthen responses |
| Exercise | Use strengthens connections; disuse weakens them |
| Readiness | Acting when ready satisfies; being forced annoys |
Thorndike revised himself in 1932. He weakened the law of exercise and concluded punishment weakens responses less than reward strengthens them.
Comparison
Pavlov studied reflexes (classical conditioning); Skinner built reinforcement on the law of effect. Köhler argued for insight learning.
Implications
Prompt positive feedback, meaningful practice and attention to readiness.
