Diagram of the procedure for Experiment 1 (shown in A) for the counterbalancing condition in which the PM intention is associated with blocks with words in uppercase and the procedure for Experiment 2 (shown in B). In both experiments, Block 1 provided baseline measures. Blocks 2, 4, 6, and 8 served as the relevant blocks in which the PM task was to be performed for PM group. Blocks 3, 5, 7, and 9 served as the irrelevant blocks in which the PM task was not relevant. PM = prospective memory.
