Cognition

Definition

In science, cognition is the set of all mental abilities and processes related to knowledge: attention, memory & working memory, judgement & evaluation, reasoning & "computation", problem solving & decision making, comprehension & production of language, etc. Human cognition is conscious and unconscious, concrete or abstract, as well as intuitive (like knowledge of a language) and conceptual (like a model of a language). Cognitive processes use existing knowledge and generate new knowledge (Wikipedia, http://en.wikipedia.org/wiki/Cognition)
