A priori contrasts for the difference between pre- and postmeasure in the 2-back task showed a trend for larger increase of the P3b in the PTG relative to the RTG group ( t (137) = 1.8, p = 0.068).

Recall from long-term semantic memory assessed by the Verbal-Fluency-Test showed a weak trend for the interaction group × session ( F (3, 137) = 2.17, p = 0.094), suggesting a slightly increased number of produced words at t 2 (49.3) than t 1 (44.4) in the CTG group, whereas no changes were observed in the remaining groups (PTG: t 1 (43.6) versus t 2 (44.2), RTG: t 1 (39.4) versus t 2 (38.8), CG: t 1 (42.6) versus t 2 (43.9).
