At any given moment we are being bombarded by physical and psychological stimuli competing for our attention. Although our eyes are capable of handling more than 5 million bits of data per second, our brains are capable of interpreting only about 500 bits per second. With similar disparities between each of the other senses and the brain, it is easy to see that we must select the visual, auditory, or tactile stimuli that we wish to compute at any specific time.
question:
Physical stimuli usually win in the competition for our attention.
From the above information, we can know a few things (always keep in mind that brain and sense organs are working together).
1) It is likely that the vast majority of information collected by sense organs such as eyes are processed and intergarated locally because our brains can only handle about 500 bits per second. 2) Brains are capable of filtering undesired information in order to process more important one. 3) Higher priority information collected by sense organs can be received by brain even when brains try to block the information from the corresponded sense organ.
