Cognitive Science is the interdisciplinary study of mind and the nature of intelligence that draws on many fields as psychology, artificial intelligence, linguistics, and philosophy; in developing theories about human perception, thinking, and learning. It spans many levels of analysis, from low-level learning and decision mechanisms to high-level logic and planning; from neural circuitry to modular brain organization. The fundamental concept of cognitive science is that “thinking can best be understood in terms of representational structures in the mind and computational procedures that operate on those structures.”
