Document Summary

Sensation: the experience of having your sense organs stimulated. Perception: interpreting the sensations that are experienced, to recognize meaningful objects & events. Ambiguous images: images with multiple interpretations (same sensation with different images) Filling-in: (pattern completion phenomena) perception that goes beyond sensation. Prosopagnosia: inability to perceive faces even though vision is fine. Bottom-up processing: analysis beginning with sensory receptors & works up to brain"s integration of sensory info (stimulus driven processing) Top-down processing: info processing guided by higher-level mental processes (experience, expectations) Psychophysics: study of relationship between physical characteristics of stimuli & our psychological experiences of them (wave length color red) Absolute threshold: minimum stimulation needed to detect particular stimulus. Difference thresholds (just noticeable difference): minimum difference a person can detect between 2 stimuli half of the time. Weber"s law: to be detectable, the stimuli must vary by constant proportion, not constant amount. Sensory adaptation: diminishing sensitivity to an unchanging stimulus. Wavelength determine color/hue: long = reds, short = blue.
