What is cognitive science?

Cognitive science is the scientific study of the mind, brain, and intelligence, particularly as it relates to mental abilities such as reasoning, decision making, memory, learning, attention, language, perception, and motor control.  This young and emerging interdisciplinary field lies at the intersection of psychology, computer science, philosophy, neuroscience, and linguistics.  Cognitive scientists aim to discover fundamental principles that underlie all forms of natural and artificial intelligence, from high-level reasoning to rapid perceptual-motor behavior.  The pursuit of this alluring and ambitious goal requires the use of various methods, tools, and perspectives.  Cognitive scientists build computational, formal, and quantitative models, conduct experimental research on behavior, and investigate neural mechanisms.  The knowledge gained by cognitive scientists has numerous real-world applications, such as the design of robots, speech recognition systems, automated reasoning systems, and human-computer interfaces.
