This document discusses several theories of motivation and behavior modification techniques. It covers Expectancy Theory, which suggests that motivation is highest when workers feel high effort leads to high performance and high performance leads to desired outcomes. Reinforcement Theory holds that behavior is a function of its consequences. Observational Learning Theory explains how people learn from observing and imitating models. Goal Setting Theory indicates that goals motivate people to improve performance. Equity Theory proposes that people evaluate if they are fairly rewarded relative to others. Behavior modification techniques aim to positively influence thoughts and behaviors, such as through punishment, extinction, shaping, timeout, and relaxation methods.
