“…Block and Block (1980) found that low regulation was associated with aggression, overreactivity to frnstration, low levels of cooperative and prosocial behavior, regression under stress, jealousy and crying easily, and lack of planfiilness and compliance (also see Pulkkinen, 1982Pulkkinen, , 1986). In addition, there is evidence that emotional arousability and temperamental intensity are associated with angry outbursts, emotional upset, aggression, and acting out behaviors (Billman & McDevitt, 1980;Brody, Stoneman, & Burke, 1988;Olweus, 1980;Teglasi & MacMahon, 1990; Thomas, Chess, & Birch, 1968), and intensity of anger is related to aggression and venting of emotion Laursen & Hartup, 1989). Thus, there is reason to believe that both emotional intensity and regulation are characteristics that are relevant to individual differences in anger and anger reactions.…”
