This document provides an overview of different learning theories: classical conditioning, operant conditioning, social learning, and cognitive learning. Classical conditioning involves associating an unrelated stimulus with a stimulus that naturally produces a response. Operant conditioning uses voluntary behaviors and consequences to shape behavior. Social learning involves observing and imitating others. Cognitive learning assumes people learn based on assigning meaning and evaluating consequences of stimuli and behavior. The document discusses examples of applications for each theory, such as treating phobias, behavior modification, observational learning in organizations, and cognitive evaluation of choices.
