Figure 1. Illustration of a scene sequence.

Participants were asked to press a key to start the sequence. Out of the 16 scenes presented, two contained white target letters that should be remembered and two contained black distractor letters that should be omitted (in the figure, only eight scenes are shown). Following the sequence, participants were first requested to type the target and distractor letter and then to decide which of two scenes was presented in the sequence (“A” or “B”). In the auditory condition, target and distractor tones were presented instead of letters. ISI – inter-stimulus interval.
