Psychology

Both sensation and perception are vital in forming an understanding of the world around us, combined they create the Complete Perceptual Experience (CPE). The process of visual sensation begins with reception. Reception is the detection of a stimuli (light) onto receptor cells in the eye, casting an image on the retina. The next stage is transduction. This involves transforming the physical energy of light that has been reflected by objects in the environment, into electrochemical energy which is transmitted to the brain. After transduction the electrochemical information is sent via the neurons along the spinal chord and received by the brain. This stage is called transmission. There is no actual distinct point in the total process of visual perception where sensation stops and perception begins as it is a continued cycle of receiving and interpreting information. Perception is a psychological and physiological process that involves the selection, organisation and interpretation of the visual information being transmitt
