IntroductionCue反应范式发现，酒精相关的线索增加酗酒者和酗酒者的酒精消费。然而，非酒精依赖的“社会”饮酒者之间的这种关系的证据是混合的，这表明，个体差异时，必须考虑到检查线索诱导的饮酒行为。一个重要的个体差异因素，可能有助于线索诱导的饮酒实验室是参与者通常在实验室外的场合喝的酒精量。也就是说，那些谁通常消耗更多的酒精每一次可以显示更大的线索诱导饮酒比那些谁通常喝less.The本研究探讨了这一假设在健康，非依赖的啤酒drinkers.MethodsThe饮酒者暴露于一系列的啤酒图像，旨在激发他们的动机喝啤酒或一系列的非酒精图像的食品，作为控制条件。线索曝光后，饮酒的动机进行了测量，让参与者有机会工作的啤酒杯通过执行操作性的反应task.ResultsResults结果表明，饮酒者暴露于酒精线索显示更大的操作性反应酒精和赚取更多的饮料相比，那些暴露于非酒精（即，食物）线索。此外，饮酒习惯的个体差异预测受试者的响应酒精暴露后的酒精线索，但不暴露于食物cooks.ConclusionsThe研究结果表明，线索诱导饮酒在非依赖饮酒者可能导致消费水平相称的典型消费实验室外，但不是过度消费，有时观察到酒精依赖的样品。
IntroductionCue reactivity paradigms have found that alcohol-related cues increase alcohol consumption in heavy drinkers and alcoholics. However, evidence of this relationship among non-alcohol dependent “social” drinkers is mixed, suggesting that individual differences must be considered when examining cue-induced drinking behavior. One important individual difference factor that might contribute to cue-induced drinking in the laboratory is the amount of alcohol that participants typically drink during occasions outside the laboratory. That is, those who typically consume more alcohol per occasion could display greater cue-induced drinking than those who typically drink less. The present study examined this hypothesis in healthy, non-dependent beer drinkers.MethodsThe drinkers were exposed to either a series of beer images intended to prime their motivation to drink beer or to a series of non-alcoholic images of food items that served as a control condition. Following cue exposure, motivation to drink was measured by giving participants an opportunity to work for glasses of beer by performing an operant response task.ResultsResults indicated that drinkers exposed to alcohol cues displayed greater operant responding for alcohol and earned more drinks compared with those exposed to non-alcohol (i.e., food) cues. Moreover, individual differences in drinking habits predicted subjects' responding for alcohol following exposure to the alcohol cues, but not following exposure to food cues.ConclusionsThe findings suggest that cue-induced drinking in non-dependent drinkers likely results in consumption levels commensurate with their typical consumption outside the laboratory, but not excessive consumption that is sometimes observed in alcohol-dependent samples.
