To examine whether a group of social drinkers showed longer response latencies to alcohol-related stimuli than neutral stimuli and to test whether exposure to 1) an alcohol-related environment and 2) consumption related cues influenced the interference from alcohol-related stimuli.
A 2 × 2 × 2 × 5 factorial design with Exposure Group (high, low) and Consumption Group (high, low) as between-participant factors and Word Type (alcohol, neutral) and Block (1-5) as within-participant factors was used. Forty-three undergraduate university students, 21 assigned to a high exposure group and 22 to a low exposure group, took part in the experiment. Exposure Group was defined according to whether or not participants currently worked in a bar or pub. Consumption Group was defined according to a median split on a quantity-frequency measure derived from two questions of the Alcohol Use Disorders Identification Test (AUDIT) questionnaire. A modified computerised Stroop colour naming test was used to measure response latencies.
Exposure and consumption factors interacted to produce greater interference from alcohol-related stimuli. In particular, the low consumption group showed interference from alcohol-related stimuli only in the high exposure condition. Exposure did not affect the magnitude of interference in the high consumption group.
Attentional bias is dependent upon exposure to distinct types of alcohol-related cues.
研究一组社交饮酒者对与酒精相关的刺激的反应潜伏期是否比对中性刺激的反应潜伏期更长，并测试接触1）与酒精相关的环境和2）消费相关线索是否会影响来自与酒精相关刺激的干扰。
采用2×2×2×5析因设计，将暴露组（高、低）和消费组（高、低）作为组间因素，单词类型（酒精、中性）和区组（1-5）作为组内因素。43名本科大学生参与了实验，其中21人被分配到高暴露组，22人被分配到低暴露组。暴露组根据参与者目前是否在酒吧或酒馆工作来定义。消费组根据从酒精使用障碍识别测试（AUDIT）问卷的两个问题得出的数量-频率测量的中位数分割来定义。使用改良的计算机化斯特鲁普颜色命名测试来测量反应潜伏期。
暴露和消费因素相互作用，产生了来自与酒精相关刺激的更大干扰。特别是，低消费组仅在高暴露条件下表现出来自与酒精相关刺激的干扰。暴露对高消费组的干扰程度没有影响。
注意偏向取决于对不同类型与酒精相关线索的暴露。
