This document summarizes key theories related to human motivation from literature. It discusses reinforcement theory, social learning theory, and need-based theories including Maslow's hierarchy of needs and Herzberg's two-factor theory. Recognition is identified as an important factor in many of these theories, satisfying social needs and the need for esteem. The literature review examines conflicting paradigms about whether rewards primarily motivate or demotivate performance, and assesses the role of recognition within these frameworks. The purpose is to build a theoretical foundation for studying the relationship between recognition and work motivation.
