Cognitivism in psychology is the study of mental processes such as memory, problem-solving, and language. It focuses on how people perceive, think, and understand the world around them. Cognitivism views the mind as an information processor, similar to a computer. For example, when a person learns a new word, cognitivism explores how the mind encodes, stores, and retrieves that information. It examines how people organize their knowledge and use it to make decisions. Cognitive psychologists study how these processes affect behavior, including how people learn, remember, and pay attention. They might investigate, for instance, how different learning strategies impact memory retention or how attention influences perception.
