Document Summary
Sensation: how our sense organs respond to external stimuli and transmit responses to brain. Perception: processing of detected sensory signals that result in internal representation of stimulus. Study of sensation and perception: study of bodily systems that convert stimulus energy into useful info. Many times, perception based on prior experience, shapes our expectations during identification of sensory experience. What we see or hear is result of brain processes that actively construct perceptual experience to allow adaption for env. After: connecting neurons in sense organs transmit info to brain. Most go first to thalamus (except smell) From thalamus to cortex, neural impulses interpreted as sight, smell, sound, touch, or taste. Sensations: transduced messages carried by nerve impulses. Quantitative: intensity, brightness, loudness, indexed by neural firing frequency, also more intense stimuli tend to recruit more neurons, color, taste, different sensory receptors respond to different qualities of a stimulus.
