Pavlov's Dogs and Operant Conditioning
Pavlov's famous experiment perfectly demonstrates classical conditioning in action. Initially, food naturally caused dogs to salivate (unconditioned response), whilst a bell produced no response. After repeatedly pairing the bell with food, the dogs learned to salivate just hearing the bell - the neutral stimulus became a conditioned stimulus.
This process follows a clear pattern: before conditioning (food → salivation, bell → no response), during conditioning food+bell→salivation, and after conditioning (bell alone → salivation). Amazingly, this technique is used today to treat alcohol addiction by pairing alcohol with substances that cause vomiting.
Operant conditioning works differently - it's about learning through consequences of your actions. Skinner's rat experiments showed how behaviour changes based on rewards and punishments. When rats accidentally pressed a lever and received food, they quickly learned to press it deliberately.
Real-world application: This explains why you're more likely to study when there's a reward (good grades) or avoid certain behaviours to escape punishment.
