Acute (day 29) and pure chronic interaction between treatment × repetition on numeric working memory accuracy: both an acute interaction (p = 0.04) and pure chronic interaction (p = 0.01) between treatment × repetition was observed on day 29. Both revealed that this effect took place at post-dose repetition 1; the acute effect compares this post-dose repetition to the day 29 pre-dose performance (p = 0.005) and the pure chronic effect compares this post-dose repetition to the day 1 baseline (p = 0.08).
