Visualization (cognitive psychology) is a cognitive process involving the creation, manipulation, and use of mental imagery. This internal mental representation, distinct from external visual displays, is a fundamental area of study within cognitive psychology. Research in this domain investigates the mechanisms by which mental images are formed, stored, and retrieved, and their functional role in various cognitive tasks, including spatial reasoning, memory encoding and retrieval, problem-solving, and creative thinking. Its significance lies in providing insights into the nature of human thought, perception, and the structure of internal mental representations, often explored through experimental methodologies within experimental psychology.
