Participants were split into two groups, one of which was given imitation-inhibition training (lower left). This consisted of placing their hand on a mouse and pressing down on both buttons; when presented with an image of the index finger raised, they had to lift the middle finger, and vice versa. The group without imitation-inhibition training (control training, right) had to lift their index finger when presented with the number 1 and the middle finger when presented with 2 (Naoyoshi Matsuda, Masaki O.
