A schematic illustration of a trial in Experiments 1 and 2 (adapted from Chang et al. [2]).

<p>The dot was green in the experiments. Later experiments used the same or similar trial procedures. Experiment 3 differed from Experiment 2 only in having a 1000 ms blank interval between the offset of the green dot and the onset of “NOW” and having a digit reproduction task after time reproduction. Experiment 4a used the same trial procedure as in Experiment 1 and Experiment 4b and 5 used the same trial procedure as in Experiment 2.
