Figure 2.

The rapid serial visual presentation (RSVP) task conditions and time-line. The left part of the figure shows the time-line of a typical trial. Each new letter was presented for 50 ms and followed by a 16.7 ms blank screen, such that letters appeared every 67 ms. The right part shows the three different trial type/conditions used in the task which were: (1) distractor-absent: the distractor stream was of just gray letters; (2) target-colored distractor: one peripheral stream contained red distractor letters which started two letters before the onset of the target in the central stream and continued until one letter after the target, making four letters in total; and (3) non-target-colored distractor: this was the same as the target-colored distractor condition except the peripheral distractor was green.
