Classical Conditioning
Ever wonder why you start feeling hungry when you hear a certain food commercial jingle? That's classical conditioning at work! Discovered by Ivan Pavlov, this form of learning involves automatic responses to associated stimuli.
The process begins with an unconditioned stimulus (UCS) that naturally triggers an unconditioned response (UCR). When a neutral stimulus is repeatedly paired with the UCS, it becomes a conditioned stimulus (CS) that can trigger a similar reaction called a conditioned response (CR).
Classical conditioning shows how our brain makes connections. Through stimulus generalization, we respond to similar stimuli the same way. With stimulus discrimination, we learn to distinguish between similar but different stimuli. Over time, the conditioned response may weaken (extinction), but it can spontaneously reappear later (spontaneous recovery).
Real-World Application: Classical conditioning helps explain phobias and how we can overcome them through therapies like flooding (intense exposure), systematic desensitization (gradual exposure), and counterconditioning (pairing fear with pleasant experiences).
In operant conditioning, developed from Thorndike's Law of Effect, behaviors followed by satisfaction are more likely to be repeated while those followed by unpleasant outcomes tend to be avoided. Reinforcement increases behaviors through either primary reinforcers (meeting biological needs) or secondary reinforcers (learned rewards like money).
