Incentive-motivational models of addiction predict that alcohol cues should elicit approach behaviours in heavy drinkers. In this study we compared heavy and light social drinkers' response latencies when required to make approach or avoidance responses to alcohol pictures. Participants completed a stimulus-response compatibility (SRC) task, which requires participants to move a manikin towards or away from alcohol-related and matched control pictures, together with self-report measures of alcohol consumption and craving. Results demonstrated that heavy drinkers, but not light drinkers, were faster to approach than avoid alcohol pictures on the SRC task. The bias to approach alcohol pictures was also associated with alcohol craving.
成瘾的激励-动机模型预测，酒精线索应会引发重度饮酒者的趋近行为。在本研究中，我们比较了重度和轻度社交饮酒者在被要求对酒精图片做出趋近或回避反应时的反应潜伏期。参与者完成了一项刺激-反应兼容性（SRC）任务，该任务要求参与者将一个人体模型移向或远离与酒精相关的图片及匹配的对照图片，同时还要完成关于酒精消费和渴望程度的自我报告测量。结果表明，在SRC任务中，重度饮酒者对酒精图片的趋近速度比对其回避速度更快，而轻度饮酒者则不然。对酒精图片的趋近偏向也与酒精渴望有关。
