There was a marginally significant difference in aggressive behavior (i.e., noise intensity) between the two game groups [ F (1, 47) = 4.02, p = 0.051, η 2 = 0.08], such that the prosocial game group assigned lower-intensity sounds to their rivals compared to the neutral game group(see Figure 2D ).

P300 amplitude decline This study also revealed that subjects who played the prosocial video game had smaller P300 amplitudes in the presence of violent words (and a weak trend for prosocial words) than did those who played the neutral video game.
