Cognitive PsychologyUltimately Cognitive psychology is the scientific investigation of human cognition, that is, all our mental abilities – perceiving, learning, remembering, thinking, reasoning, and understanding. It is closely related to the highly interdisciplinary cognitive science and influenced by artificial intelligence, computer science, philosophy, anthropology, linguistics, biology, physics, and neuroscience. The term “cognition” stems from the Latin word “cognoscere” or "to know". Fundamentally, cognitive psychology studies how people acquire and apply knowledge or information.
