Many theoretical perspectives suggest that alcohol-related stimuli bear on attentional processes. Building upon these ideas and recent advances regarding the attention-constricting impact of approach motivational states, we predicted that mere exposure to alcohol-related images would suffice to reduce the breadth of attention among individuals who possessed a strong motivation to consume alcohol.
Two studies exposed participants to alcohol and neutral cues prior to assessing attention structure. In both studies, measures of alcohol use, negative alcohol expectancies, trait approach motivation and alcohol-related approach motivation were assessed.
Study 1 comprised 102 undergraduates and study 2 comprised 161 undergraduates. Studies were conducted at Texas A&M University, College Station, Texas.
In both studies, participants were briefly exposed to pictures of various stimuli (alcohol versus neutral pictures). After each picture was displayed, participants completed a trial assessing attentional focus.
After controlling for relevant covariates, both studies demonstrated that exposure to alcohol-related pictures led to a narrowing of attentional focus among individuals who possessed a strong motivation to use alcohol. Exposure to neutral pictures, however, did not interact with alcohol-related motivation to influence attentional focus.
Alcohol cues narrow attentional breadth for individuals who are motivated to consume alcohol, suggesting a non-pharmacological means in which alcohol produces a narrow mindset. Alcohol cues may contribute to cognitive and behavioral deficits, as well as drinking behaviors, in part, because they lead to the inability to process a broad range of information in the environment.
许多理论观点表明,与酒精相关的刺激与注意力过程有关。基于这些想法以及最近关于接近动机状态对注意力限制影响的进展,我们预测,仅仅接触与酒精相关的图像就足以减少那些强烈渴望饮酒的个体的注意力广度。
在评估注意力结构之前,两项研究都使参与者接触酒精和中性线索。在这两项研究中,都评估了酒精使用、负面酒精预期、特质接近动机和与酒精相关的接近动机的测量。
研究 1 包括 102 名本科生,研究 2 包括 161 名本科生。研究在德克萨斯州农工大学学院站进行。
在这两项研究中,参与者都短暂地接触了各种刺激的图片(酒精与中性图片)。在显示每张图片后,参与者完成了一项评估注意力焦点的测试。
在控制了相关协变量后,两项研究都表明,接触与酒精相关的图片会导致那些强烈渴望饮酒的个体的注意力焦点变窄。然而,接触中性图片并不会与与酒精相关的动机相互作用,从而影响注意力焦点。
酒精线索会使有饮酒动机的个体的注意力广度变窄,这表明酒精产生狭隘思维的一种非药理学手段。酒精线索可能导致认知和行为缺陷以及饮酒行为,部分原因是它们导致个体无法处理环境中广泛的信息。
