Learning theories in psychology explain how organisms acquire new behaviors and knowledge through different mechanisms.
Classical conditioning, first demonstrated by Pavlov, involves learning through association where a neutral stimulus becomes paired with a naturally occurring response. The key components include the unconditioned stimulus (US), unconditioned response (UR), conditioned stimulus (CS), and conditioned response (CR). Through repeated pairings, organisms learn to respond to previously neutral stimuli. Higher order conditioning occurs when a conditioned stimulus is used to condition another neutral stimulus.
Operant conditioning theory focuses on how behaviors are modified through consequences. Based on Thorndike's Law of Effect, behaviors followed by satisfying consequences tend to be repeated while those followed by unpleasant consequences tend to decrease. Key principles include positive reinforcement, negative reinforcement, punishment, and extinction. Discrimination involves responding differently to similar but distinct stimuli, while generalization refers to responding similarly to related stimuli. Extinction occurs when a previously reinforced behavior is no longer reinforced, leading to its decrease. The effects of punishment on behavior can include suppression of unwanted responses, though it may have unintended negative consequences like anxiety or aggression.
The shift from strict behaviorism to cognitive psychology represented a major theoretical advancement. While behaviorism focused solely on observable behaviors, cognitive learning theory emphasizes internal mental processes like attention, memory, and problem-solving. Observational learning, demonstrated in Bandura's famous Bobo doll experiments, showed that individuals can learn new behaviors simply by watching others perform them. This integrated approach recognizing both external and internal factors provides a more complete understanding of learning. Modern perspectives acknowledge the value of both behavioral and cognitive approaches, along with constructivism which emphasizes how learners actively build knowledge through experience and reflection. These theories continue to inform educational practices and our understanding of human learning and development.
