a Experiment 1: perception task. Participants determined the net direction (left or right) of a motion coherence stimulus. Difficulty was manipulated by varying the proportion of dots that moved coherently. b Experiment 2: memory task. Participants viewed a sequence of three unique stimuli. The sequence was occluded by a mask, and the final frame appeared, containing a stimulus to the left and to the right. One was an “old” stimulus from the sequence, and the other was a “new” stimulus that had never appeared before. Participants determined whether the stimulus to the left or right was “old”. Difficulty was manipulated by varying the amount of time (signified by Δ ms) between stimuli in the sequence.
