Document Summary

Module 18: basic concepts of sensation and perception. *sensation: (the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment). Heather sellers curious mix of perfect vision and face blindness illustrates the distinction between sensation and perception. When she looks at a friend, her sensation is normal: her sensory receptors detect the same information yours would, and her nervous system transmits that information to her brain. *perception: (the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events). Her perception the process by which her brain organizes and interprets sensory input is almost normal. Thus, she may recognize people from their hair, gait, voice, or particular physique, just not their face. *bottom- up processing: (analysis that begins with the sensory receptors and works up to the brain"s integration of sensory information).
