| A | B |
|---|
| Way sensory system operates on physiological level | sensation |
| external agent activates specific sensory receptor | stimulus |
| process changing external agento into neural message | transduction |
| process of giving awareness to sensory message | attention |
| Point a sensory receptor reacts to incoming message | Threshold |
| Below the point of activating a sensory response | subliminal |
| Minimum detectable + or - in message strength | just noticeable difference |
| Condition - familiary sensory experiences decrease with continued exposure | sensory adaption |
| study of limits of sensory cells | psychophysics |
| To reach absolute threshold, stimulus must activate | 50% of time |
| Determining the just noticeable difference | Weber's Law |
