Document Summary

We see things that aren"t actually there all the time. Sensation: detection of physical energy from the environment and converting into a neural signal. Perception: selection, organization, and interpretation of sensory information. Our experience of that thing, how we understand it. Analysis of the stimulus begins with the sense receptors and works up to the level of the brain and mind. Information processing guided by higher-level mental processes as we construct perceptions, drawing on our experience and expectations. Nothing special about first and last letter, but rather brain narrows down possibilities. Only can be done with extensive reading training. Brain makes predictions so we don"t have to read every letter. A study of the relationship between physical characteristics of stimuli and our psychological experience with them. The transformation of physical energy (sights, sounds, smells) into neural impulses. Minimum stimulation needed to detect a particular stimulus 50% of the time.
