Experimental and Clinical Psychopharmacology, vol. 11, no 2, p. 158-166.
Intentions : Observer les liens entre l’agressivité, les antécédents familiaux d’alcoolisme et le rythme cardiaque suivant une surconsommation d’alcool.
Questions/Hypothèses : « Thus, we first hypothesize that individuals who are both at high risk for alcoholism (SOMAs [sons of male alcoholics] ) and are aggressive would be characterized by the largest increased HR response to alcohol, as compared with low-aggressive SOMAs, high aggressive non-SOMAs, and controls. Second, we further hypothesize that the high-aggressive SOMAs would selfreport the most alcohol consumption compared with the other three groups. » (p. 159)
Échantillon/Matériau : « Participants for this study were drawn from a longitudinal cohort of 1,037 males who have been followed since 1984 when they attended kindergarten in low socioeconomic areas of Montreal, Quebec, Canada (Tremblay, Pihl, Vitaro, & Dobkin, 1994). » (p. 159)

« Some sons of male alcoholics (SOMAs) are characterized by an increased heart rate (HR) response to alcohol intoxication, which is thought to reflect increased sensitivity to alcoholinduced reward. Such a response has also been related to increased physical aggression. However, the confounding effect of aggression in SOMAs may be obscuring the interpretation of these findings. The HR response to alcohol was therefore assessed in 4 groups: high/low aggressive SOMAs and high/low aggressive non-SOMAs. Results indicate that aggressive SOMAs had the highest intoxicated HR response and that they reported the most alcohol consumption. This suggests that in some cases the high comorbidity between alcohol misuse and aggression is related to an increased sensitivity to alcohol-induced reward. » (p. 158)
