You are watching your friend very closely as she speaks to you and notice that she is blinking at a rate of 20 per minute. You wonder why she does not experience blackouts of visual stimuli when she blinks

Later in the day you ask your psychology teacher if he has an explanation. What will he tell you?
a) The brain distracts itself from visual stimuli and focuses on other stimuli during brief blackouts.
b) Although the blinking stops visual processing, the brain simply ignores the blackouts because they are so brief.
c) The brain has evolved to the point that it fills in gaps when stimuli are not being sent as occurs during the brief blinking periods.
d) When the brain signals a blink, it inhibits activity in the visual system, so the information about the visual blackout is not transmitted.
