#Cognition 

(/kɒɡˈnɪʃ(ə)n/ (About this soundlisten)) refers to "the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses".[2] It encompasses many aspects of intellectual functions and processes such as attention, the formation of knowledge, memory and working memory, judgment and evaluation, reasoning and "computation", problem solving and decision making, comprehension and production of language. 

Cognitive processes use existing knowledge and generate new knowledge. weki   Cognitive processes are analyzed from different perspectives within different contexts, notably in the fields of linguistics, anesthesia, neuroscience, psychiatry, psychology, education, philosophy, anthropology, biology, systemics, logic, and computer science.[3] These and other different approaches to the analysis of cognition are synthesised in the developing field of cognitive science, a progressively autonomous academic discipline.
