Alcohol-Related Aggression in Males and Females: Effects of Blood Alcohol Concentration, Subjective Intoxication, Personality, and Provocation 总被引:1,自引:0,他引:1
This study tested the combined predictive ability of blood alcohol concentration (BAC), subjective intoxication, and aggressive personality traits on physical aggression in males and females in Highland Low-provocation conditions. Sixty intoxicated White social drinkers (30 males and 30 females) competed against a fictitious opponent on a modified version of the Taylor aggression paradigm in which subjects both received and delivered electric shocks to their opponents in provoking and nonprovoking conditions. Provocation conditions (High and Low) were defined by the intensity of the shocks the subjects received. Aggression was operationalized as the intensity of the shocks selected by the subjects. Results indicated that, for males in the High-provocation condition, aggressive personality traits, subjective intoxication, and BAC were effective predictors of physical aggression. However, in the Low-provocation condition, only aggressive personality traits and BAC predicted aggression. None of the variables were effective predictors of aggression for intoxicated females. 相似文献

The effects of experimentally induced and personally relevant stressors on low back EMG activity during 3 phases of the menstrual cycle in women with the premenstrual syndrome (PMS) and premenstrual low back pain were examined. Thirty-nine women reporting either PMS and premenstrual severe low back pain (group 1), PMS with premenstrual moderate low back pain (group 2), or those reporting neither condition (group 3) participated. During each of 3 menstrual phase-specific assessment sessions, participants were exposed to a neutral stimulus, an experimentally induced stressor, and 2 personally relevant stressors in a randomized order. Concomitant monitoring of low back EMG activity and heart interbeat interval was undertaken. Results indicated that participants in group 1 evidenced greater EMG changes in response to personal stressors compared to the neutral stimulus and experimentally induced stress during the premenstrual phase. EMG activity in response to personal stress was also significantly higher during the premenstrual phase than during the menstrual and intermenstrual phases for group 1, and higher than EMG changes evidenced by groups 2 and 3 during the same phase. Group 2, while not reporting as severe premenstrual back pain as did group 1, reported moderate levels of back pain and evidenced greater physiological reactivity to a personal stressor than did group 3. The findings highlight the link between personally relevant stressors and concomitant physiologic responsivity and the role that this arousal may play in the maintenance and exacerbation of premenstrual low back pain. 相似文献
