Document Summary

Common definition: perception is the process of extracting information from the environment. (this is complete however), this cannot be the whole story. Using knowledge not in the stimulus bit of which is in your head, if you don"t know what a triangle is, you would not see it (pacman example). Context is important, and perception clearly involves more than extracting information from the environment. Perception: the conscious experience of objects and object-relations. Metatheory: a set of untestable assumptions about the world that form a framework for subsequent scientific behaviour. Theories can be tested, but with meta-theories we can not. Plate and aristotle said we have a body and mind-dualism. Body is a physical existence and the mind is thinking and perceiving and decision making. Descartes-body ad mind interact with the pineal gland, doesn"t though . In the 1800"s they decided to disregard dualism and there is only really monism.
