The document summarizes several behaviorist theories of learning: - Classical conditioning (Pavlov): Learning through associations between stimuli and responses. An example is Pavlov's dogs salivating to the sound of a bell after it was paired with food. - Operant conditioning (Skinner): Learning through consequences that reinforce behaviors. Behaviors are strengthened if they produce positive reinforcement or reduce negative reinforcement. - Social learning theory (Bandura): Extended Skinner by arguing learning also occurs through observation and imitation of others in a social environment. People can learn behaviors by watching others and processing the situation.
