Document Summary

Psych 111 - chapter 6 - sensation and perception. Sensation the way our sensory receptors and nervous system receive and represent stimulus energies from our environment. Analysis that begins at the sensory receptors and works up to higher. How we organize and interpret sensory information, enabling us to recognize meaningful objects and events. Top-down processing information processing guided by higher-level mental processes, drawing on our experience and expectations. All our senses receive sensory information transform that stimulation into neural impulses. Psychophysics studies the relationship between physical energy we detect and its effects on our psychological experiences. Absolute threshold is the minimum stimulus energy needed to detect a particular stimulus 50 percent of the time. Signal detection theory predicts how and when we detect the presence of a faint stimulus (signal) and background stimulus (noise) Seeks to understand why people respond differently to the same stimuli.
