Our negative finding for the verbal fluency task is in line with the only other study using the same task [In sum, for the exploratory tasks, overall the evidence does not support a creatine effect. However, as the evidence for the Stroop task shows, this might be only when the tasks are made too easy for participants, so that creatine has no chance to help.
