Document Summary

Stimulus received > transduction > feature detector analyses > reconstruction into neural representation. > compared to schemas > match results in recognition and interpretation. Sensation is stimulus detection by which our organs respond to & translate environmental stimuli into nerve impulses that are sent to the brain. Perception is the organization & interpretation of these neural signals depending on context. When sensory receptors translate a stimulus into a nerve impulse, it is called transduction. This is done by action of photo pigments. After this translation, feature detectors break down the stimulus, analyze it & compare the pieces" to our store of knowledge to recognize the stimulus. Scientific study of relationship b/w stimuli & sensory experiences: absolute limits of sensitivity, diffs b/w stimuli. Absolute threshold: lowest intensity at which the weakest stimulus is detected 50% of the time. The lower the absolute threshold the greater the sensitivity.
