Perception, in scientific disciplines relating to the study of cognition &mdash; amongst many, cognitive science, philosophy, psychology, and neuroscience &mdash; refers to the manner by which intelligent life-forms receive information about the outside world through their sensory organs, and subsequently apply information processes to that information in order to use it meaningfully to make decisions about their environment. The definition of the term has varied significantly according to context and methodology employed by those authors using the term, and as a consequence, not all works discussing it are necessarily referring to a common subject.
