Cognitive psychology is the scientific study of mental processes, including how people perceive, think, remember, learn, solve problems, and make decisions. As a branch of psychology that emerged in the 1950s and 1960s as a reaction to behaviorism, it focuses on internal mental states rather than purely observable behavior. The cognitive revolution, spearheaded by researchers such as Ulric Neisser, George Miller, and Noam Chomsky, established the mind as a legitimate subject of scientific inquiry by drawing analogies between human cognition and information processing in computers.
The field investigates a wide range of mental functions, including attention, perception, memory, language, problem-solving, creativity, and reasoning. Cognitive psychologists use experimental methods to build models of how the mind encodes, stores, and retrieves information. Key frameworks such as the multi-store model of memory, schema theory, and dual-process theory have profoundly shaped our understanding of why people think and behave the way they do. Research in cognitive psychology has also revealed systematic errors in human thinking, known as cognitive biases, which affect judgment and decision-making in predictable ways.
Today, cognitive psychology intersects with neuroscience (forming cognitive neuroscience), artificial intelligence, linguistics, education, and clinical therapy. Its practical applications span from designing user-friendly technology and improving educational methods to treating mental health conditions through cognitive-behavioral therapy. Understanding cognitive processes is essential for anyone seeking insight into human behavior, learning, communication, or the design of systems that interact with human minds.
