Document Summary

Synesthesia: mixing of the senses they may experience sounds as colours or tastes as touch sensations that have different shapes. Sensation: the stimulus-detection process by which our sense organs respond to and translate environmental stimuli into nerve impulses that are sent to the brain. Perception: the active process of organizing this stimulus input and giving it. Transduction: the process whereby the characteristics of a stimulus are meaning. converted into nerve impulses and sensory capabilities. Psychophysics: studies relations between the physical characteristics of stimuli. Absolute threshold: the lowest intensity at which a stimulus can be detected. The lower the threshold, the greater the sensitivity. Decision criterion: a standard of how certain they must be that a stimulus is present before they will say they detect it. Signal detection theory: factors that influence sensory judgements. Subliminal stimulus: one that is so weak or brief that, although it is received by the senses, it cannot be perceived consciously.
