This document discusses perception and learning in organizations. It defines perception as the process of receiving information and making sense of the world. Selective attention and confirmation bias can influence what information we notice and believe. Mental models help us interpret information but can also block new perspectives. Learning is a relatively permanent change in behavior from interacting with the environment. Both explicit knowledge from documents and tacit knowledge from experience are important. Behavior modification uses reinforcement to change behavior, while social learning emphasizes modeling and self-reinforcement. Organizational learning involves acquiring, sharing, and applying knowledge across an organization.
