Juggling two independant sources of sensory input at the same time is called what?
multitasking
why is sensory processing useful?
An unchanging stimulus is less likely to require immediate action, constantly sensing stimuli that are always in our environment would be very distracting, it better allows our sense to selectively respond to important changes in stimulation
Why are reasons that sensory adaptation is not useful?
stimuli that change frequently usually are of no consequence, and therefore not important to sense.

viewing one colour fatigues cells assosiated with that colour and subsequently results in an overall response that emphasizes the opponent colour
