This document provides an overview of organizational behavior concepts and research methodology. It discusses three major theoretical frameworks that inform the study of organizational behavior - cognitive framework, behavioristic framework, and social cognitive framework. The cognitive framework views behavior as influenced by internal mental processes, while the behavioristic framework focuses on observable stimulus-response relationships. The social cognitive framework proposes a model of triadic reciprocal causation where personal factors, environmental influences, and behavior continually interact. The document emphasizes the importance of valid and rigorous research methodology to establish evidence-based understanding of organizational behavior.
