Document Summary

Sensaion the process by which our sensory receptors and nervous system receive and represent simulus energies from our environment. Percepion the processes by which her brain organizes and interprets sensory input is almost normal. Analysis that begins with the sensory receptors and works up to the brain"s integraion of sensory informaion. Informaion processing guided by higher-level mental processes, as when we construct percepions drawing on our experience and expectaions. Receive sensory simulaion, oten using specialized receptor cells. Deliver the neural informaion to our brain. Conversion of one form of energy into another. In sensaion, the transforming of simulus energies, such as sights, sounds, and smells, into neural impulses our brain can interpret. The study of relaionships between the physical characterisics of simuli, such as their intensity, and our psychological experience of them. The minimum simulus energy needed to detect a paricular simulus 50 percent of the ime.
