Attentional blink task.

<p>Subjects viewed RSVP streams of letters. Target 1 (T1) was colored red, Target 2 (T2) green, and the distractors white. T2 could appear at Lag 2, 4 or 10. In the prime present trials, a distractor (priming distractor, PD) with the same identity as T2 appeared at Lag2. All stimuli had different identities in the prime absent trials. Subjects were required to report T1 and T2 at the end of each stream.
