Wundt proposed a theory of human psychological perception and consciousness. He drew a parallel from what his contemporaries studying physics and chemistry were doing, that is breaking down substances into chemical elements (atoms); attempting to do the same for human psychology, Wundt proposed that a complex human perceptual experience could be decomposed into elementary sensations. He proposed introspection (self-examination) as the guide to source the information on what is going on in a perception experience, and to break it down into sensory components.Mather, George (2006) Foundations of Perception, Psychology Press, ch.1 p.32
