Document Summary

Synesthesia a condition which someone can see colors or sense taste while listening to music or reading. Psychophysics study of how stimuli are translated into experience. Sensation active absorption of energy by sensory organs. Perception acting organizing, translating what the stimuli means. Threshold a point where energy levels or either detected or not. As stimulus intensity increase, subject probability of responding to a stimuli increases. An absolute threshold minimum amount of stimuli point where the organism can detect. Jnd just noticeable difference the smallest difference in amount of stimulation that an organism can detect. Weber"s law: (cid:862)the size of noticeable difference is a constant proportion of the size of the initial stimulus.
