There are many stimuli in your environment of which you are
not aware. You use attention to filter out unimportant stimuli and focus
on relevant stimuli. However, there are circumstances under which you
cannot perceive stimuli, regardless of how hard you "pay attention." One
situation is when visual stimuli are presented in quick succession. If
the interval between the two stimuli is short enough, you do not
perceive the second stimulus. This lapse in attention is known as
attentional blink. In this assignment, you will experience the
attentional blink for yourself and will also read about practical
implications of the phenomenon.
