本研究探讨了药物提示暴露对吸烟者工作记忆表现的影响。被剥夺12小时的成年吸烟者（N=23）进行了一项工作记忆任务，在此期间，他们暴露于三种与任务无关的刺激：含有吸烟相关内容的图片，没有吸烟内容的图片和注视交叉。与先前的研究一致，我们发现药物线索暴露会影响后续项目的加工（即结转效应）。具体来说，我们发现，在包含吸烟提示的中性图片的实验中，工作记忆的表现比在包含吸烟相关刺激的中性图片的实验中表现得更差。先前观察到的吸烟线索暴露对认知过程的影响是重复的，但只是在排除了受携带效应影响的试验之后。这些结果重复和扩展了先前的研究，证明了类似的效果，并突出了结转效应的重要方法和概念含义。
The present study investigated the effects of drug cue exposure on working memory performance in cigarette smokers. Adult smokers (N=23) deprived for 12 hr performed a working memory task during which they were exposed to three types of task-irrelevant stimuli: Pictures containing smoking related-content, pictures devoid of smoking content, and a fixation cross. Consistent with prior research, we found that drug cue exposure affected the processing of subsequent items (i.e., carry-over effects). Specifically, we found that working memory performance was worse on trials containing neutral pictures preceded by trials containing smoking cues compared with performance on trials containing neutral pictures preceded by trials not containing smoking-related stimuli. Previously observed effects of smoking cue exposure on cognitive processing were replicated but only after removing trials subject to carry-over effects. These results replicate and extend previous research demonstrating similar effects and highlight the significant methodological and conceptual implications of carry-over effects.
