Document Summary
Learning objectives: define the processes of sensation and perception, and discuss how these processes work together, define psychophysics and describe absolute threshold, difference threshold, sensory adaptation. 3. and signal detection methods of detecting stimuli. Sensory processes: define the processes of sensation and perception, and discuss how these processes work together, define psychophysics and describe absolute threshold, difference threshold, sensory adaptation and signal detection methods of detecting stimuli. Stimulus received transduction feature detectors analyze reconstructed to neural representation compared with previously stored information matching process= recognition and interpretation perception. Sensation: stimulus-detection process where sense organs respond to and translate environmental stimuli into nerve impulses that are sent to the brain. Perception: active process of organization of stimulus and giving it meaning. Transduction: process where characteristics of a stimulus are converted to nerve impulses. Psychophysics: studies relations between physical characteristics of sensory stimuli and sensory capabilities: absolute limits of sensitivity, differences between stimulus (smallest difference to experience a different sensation)
