The analysis of the effects of personality traits revealed that neuroticism had a significant positive effect in the WM training tasks, r = 0.39, p = 0.048, and a negative trend effect, r = −0.35, p = 0.060, on the improvement in the n -back transfer task, while there was no significant effect, r = −0.01, p = 0.974, in the word list task.
