Document Summary

Everyone experiences a different reality when someone dies so does their universe. Sensation the process by which our sense organs responds to and translate stimuli into nerve impulses sent to the brain. Perception organizing the stimulus input and giving it meaning based on prior experience, expectations, etc. Sensory receptors translate information into nerve impulses info received in one form of energy is transduced into a different form. Stimulus pieces are reconstructed and compared to stimuli in memory. Absolute limits 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 and it is subject to variation with changes in circumstances. Ask subject to report sensation for each hand separately. Although both hands are in the same water, the sensations differ due to the prior adaptation.
