These four senses are compiled in our brain and processed as cautionary information that jump starts our response. That is one of the reasons that absolute thresholds are very important to understand. There is one problem with these thresholds though. They are dependent on the person’s abilities at processing inputs and perceiving change applied to their five senses.
