Document Summary
Sensation and perception are different, yet integrated processes. The process of detecting and then translating he complexity of the world into meaningful experiences occurs in two stages: sensation: the process of detecting external events by sense organs and turning those stimuli into neural signals. At a sensory level, sound of someone"s voice is simply noise, a sight of someone is just shapes and colour. This raw sensory information is then relayed to the brain where perception occurs: perception: involves attending to, organizing, and interpreting stimuli that we sense. Include recognizing the sounds as a human voice and understanding that certain colours, shapes, and motion together make up the image of the human being. The raw sensations detected by the sensory organs are turned into information that the brain can process through transduction. Transduction: when specialized receptors transform the physical energy of the outside world into neural impulses.
