Document Summary

The process whereby sensory organs gather information from the outside world. Refers to the stimulation of the sensory organs. The process whereby we organized and interpret our sensations. A sensation begins and is followed by a perception: there is no scientific way to determine where these sensations transition into perceptions. Mental predisposition to perceive one thing and not another. Setting you up to perceive something in a certain way over another. You were primed to see the rabbit at the beginning of the semester. Represents the interplay between the inside and outside world. The mind, and the physical properties of external stimuli that we come across. The study of how physical stimuli are translated into psychological experience. How to we perceive stimuli in the external world. Goes on the assumption that you have a particular threshold: the point at which a stimulus is detected. In reality, an exact, absolute threshold cannot be determined, since there are individual differences.
