Figure 2. Number of calculations for congruent (ascending motion–additions; descending motion–subtractions) and incongruent pairings (ascending motion–subtractions; descending motion–additions) performed experiencing (i.e., real) or imagining (i.e., imagined) the motions through a passive (i.e., elevator) or active (i.e., stairs) mode.
Bars are standard error of the mean.
