Sensory receptors translate information into nerve impulses. Stimulus pieces are reconstructed and compared to stimuli (stored records) in memory pattern recognition . Perception is then consciously experienced *only once the previous four have been accomplish* Absolute limits (lymen) of sensitivity: dimmest light in which we can see objects, softest sound we can hear. Recognizing differences between stimuli: smallest difference in brightness detectable, recognizing differences between tones. The amount of energy required to overcome the adaptation level is known as the differential threshold it is subject to variation with changes in circumstances.
