Based on Gray's Reinforcement Sensitivity Theory, the influence of behavioural disinhibition upon alcohol consumption was studied. A sample of undergraduates answered different questionnaires related to the Behavioural Inhibition System and Behavioural Activation System. In relation to alcohol use, three aspects of alcohol consumption were assessed: frequency, quantity of alcohol intake and the age at first drink. From a series of correlation and regression analyses, we found that both high scores on BAS-related scales and low scores on those scales related to the BIS were jointly associated with current alcohol-taking habits. Additionally, the Sensitivity to Reward (SR) scale (BAS) was negatively correlated with, and a predictor of, the onset age of alcohol use. We conclude by proposing that research on alcohol use can benefit from this well-grounded theory of the neuropsychology of the individual differences.
基于格雷的强化敏感性理论，研究了行为抑制对酒精消费的影响。一组本科生样本回答了与行为抑制系统和行为激活系统相关的不同问卷。关于酒精使用，评估了酒精消费的三个方面：频率、酒精摄入量和首次饮酒年龄。通过一系列相关分析和回归分析，我们发现与BAS相关量表的高分和与BIS相关量表的低分都与当前的饮酒习惯相关。此外，奖励敏感性（SR）量表（BAS）与酒精使用的起始年龄呈负相关，且是其预测指标。我们最后提出，对酒精使用的研究可以从这个关于个体差异神经心理学的有充分依据的理论中受益。
