Illustration of a trial used in the experiment.
Participants first viewed the memory cue for 100 ms or 1000 ms and retained its color. In the retention interval, they searched for a target line and specified its direction. Finally, they were shown a second item and judged whether its color matched the memory cue (here the color changed).
