Cognitive science: The study of the mind. Cognitive science is an interdisciplinary science that draws on many fields, including neuroscience, psychology, philosophy, computer science, artificial intelligence, and linguistics. The purpose of cognitive science is to develop models that help explain human perception, thinking, and learning with the premise that the mind is an information processor. This processor receives, stores, retrieves, transforms, and transmits information. The information and the corresponding information processes can be studied as patterns.
