Franken's attentional bias hypothesis proposes that attentional bias to alcohol (ABA) activates craving, which motivates alcohol consumption behavior. While this hypothesis was put forward to account for alcohol dependence, the present study tested whether Franken's model may potentially contribute to explaining variation in beer consumption among young social drinkers.
ABA was measured by presenting participants with dual videos, one showing alcoholic beverages and the other non-alcoholic beverages, and assessing relative attention to each using a visual probe procedure. Self-reported alcohol craving was assessed four times over the session. In vivo alcoholic beverage consumption was assessed by the remaining weight of alcohol bottle following consumption, measured at conclusion of the experiment.
The study revealed that ABA positively predicted alcohol craving ( < .01) and in vivo beer consumption ( < .01). The relationship between ABA and beer consumption was fully mediated by craving (β = .63, 95% CI [.04, 1.29]).
To our knowledge, this is the first study to show that the relationship between ABA and in vivo alcoholic beverage consumption is fully mediated by alcohol craving. Future research can extend understanding of the causal relationship between ABA, craving, and consumption, by determining whether direct modification of ABA influences alcohol consumption by altering craving.

弗兰肯的注意偏向假设提出，对酒精的注意偏向（ABA）会激活渴望，从而促使饮酒行为。虽然该假设是为了解释酒精依赖，但本研究检验了弗兰肯的模型是否可能有助于解释年轻社交饮酒者啤酒消费的变化。
通过向参与者呈现双视频来测量 ABA，一个视频显示酒精饮料，另一个视频显示非酒精饮料，并使用视觉探测程序评估对每个视频的相对注意力。在整个会议期间四次评估自我报告的酒精渴望。通过在实验结束时测量剩余酒精瓶的重量，评估体内酒精饮料的消耗。
研究表明，ABA 与酒精渴望（<.01）和体内啤酒消费（<.01）呈正相关。ABA 与啤酒消费之间的关系完全由渴望介导（β=.63，95%CI [.04，1.29]）。
据我们所知，这是第一项表明 ABA 与体内酒精饮料消费之间的关系完全由酒精渴望介导的研究。未来的研究可以通过确定直接改变 ABA 是否通过改变渴望来影响饮酒，从而扩展对 ABA、渴望和消费之间因果关系的理解。
