The document discusses several theories of learning:
1) Behavioral theories including Pavlov's classical conditioning, Thorndike's law of effect, and Skinner's operant conditioning which use reinforcement and consequences to shape behavior.
2) Social learning theory developed by Bandura which emphasizes learning from observing and modeling others, involving attention, retention, reproduction, and motivation.
3) Definitions of learning focus on acquisition of knowledge, skills, and attitudes through experience that enables better adaptation. Learning is explained as a reflective process that develops understanding or changes mental processes.
