At any given moment are being bombarded by physical and psychological stimuli
computing for one attention. Although our eyes are capable of handling more
than 5 millions of data per sec, our brains are capable of interpreting only about
500 bits per sec. with similar disparities between other senses and brain it is
easy to see that select visual, auditory or tactile stimuli that we wish to compute
at any specific time.
10.physical stimuli usually win the competition for our attention.
