Outline of some typical trials. Panel A, Working Memory (WM) Task trial. Panel B, two trials in the Long-Term Memory (LTM) Task. The memory array set size in the WM task varied between 2, 4, or 6 items, and the presentation time was adjusted to be 250 ms per item. During the WM response phase, participants indicated whether they had seen the probe item in the Memory Array or not, and also selected their level of confidence, by clicking on the relevant option. In the LTM task, participants indicated whether they had previously seen the probe items in the WM task. This figure is presented in greyscale. In the real experiment, the response scale was green for the three response options indicating having seen the object, and red for the options indicating not having seen the objects.
