Maslow's Hierarchy of Needs theory proposes that individuals are motivated by a hierarchy of needs, with the most basic needs (physiological and safety) needing to be satisfied before higher-level needs (esteem and self-actualization) can be addressed.

Herzberg's Two-Factor Theory divides factors into hygiene factors (extrinsic factors that prevent dissatisfaction) and motivation factors (intrinsic factors that lead to satisfaction). Company policies and working conditions are hygiene factors.

McClelland's Achievement Motivation Theory proposes that individuals have a need for achievement, which drives them to set challenging goals and strive for success.

Expectancy Theory proposes that motivation is determined by an individual's expectancy (belief that effort will lead to performance) and valence (value placed on the outcome of performance).

Goal-Setting Theory proposes that specific, measurable, achievable, relevant, and time-bound goals lead to higher motivation and performance.

Equity Theory proposes that individuals are motivated to maintain a balance between their inputs (efforts, skills, experience) and outputs (rewards, recognition) to avoid feelings of inequity.

Social Learning Theory emphasizes the role of observational learning, imitation, and modeling in shaping an individual's motivation and behavior.

Reinforcement Theory proposes that behavior is influenced by its consequences, with positive consequences (reinforcement) increasing the likelihood of a behavior being repeated and negative consequences (punishment) decreasing the likelihood of a behavior being repeated.

Self-Determination Theory emphasizes the importance of intrinsic motivation, where individuals are driven by internal factors such as enjoyment, personal growth, and autonomy.

Porter and Lawler's Expectancy Theory proposes that motivation is influenced by an individual's effort-performance expectancy (belief that effort will lead to performance), performance-outcome expectancy (belief that performance will lead to desired outcomes), and outcome valence (value placed on the outcomes).

Goal-Setting Theory emphasizes the importance of setting challenging goals and providing feedback to enhance motivation and performance.

Maslow's Hierarchy of Needs proposes a hierarchy of needs, with physiological needs (e.g., food, water, air) considered the most basic and fundamental.

Equity Theory emphasizes the importance of social comparison and fairness in the workplace, suggesting that individuals are motivated to maintain a balance between their inputs (efforts, skills, experience) and outputs (rewards, recognition).

McClelland's Achievement Motivation Theory proposes that individuals with a high need for achievement are characterized by a strong desire to succeed, a preference for challenging goals, and a fear of failure.

Self-Determination Theory emphasizes the importance of autonomy (control over one's work), competence (feeling capable and effective), and relatedness (feeling connected to others) in the workplace.
