“…In particular, the significant priming effect of violent picture was found in both participants with HA and MA, but not in LA. This result was in line with previous researches, which showed that the moderately aggressive and highly aggressive boys differed from the nonaggressive boys on attributional biases, and that severely aggressive displayed more social-cognitive dysfunctions than moderately and lowly aggressive boys (Bushman, 1995;Anderson, 1997;Lochman & Dodge, 1994;Widom, 1989;Virkkunen, Kallio, & Rawlings, 1994;Anderson, Anderson, Dill, & Deuser, 1998;Craig, Browne, Beech, & Stringer, 2006). Moreover, the result was in agreement with prior researches, and were also correspondent with the expected hypotheses, which assumed that individuals with HA had higher aggression than others (Bushman, 1996).…”
