How the smell of alcohol impacts alcohol-related thoughts and behaviours is unclear, though it is well-documented that alcohol-related stimuli and environments may trigger these.
The current study, therefore, aimed to investigate the priming effects of both visual and olfactory alcohol cues on inhibitory control.
Forty individuals (M age = 23.65, SD = 6.52) completed a go/no-go association task (GNAT) which measured reaction times, response accuracy and false alarm rates whilst being exposed to alcohol-related (or neutral) olfactory and visual cues.
Alcohol-related visual cues elicited lower false alarm rates, slower reaction times and higher accuracy rates relative to neutral pictorial cues. False alarm rates were significantly higher for those exposed to alcohol as opposed to neutral olfactory cues.
By highlighting that exposure to alcohol-related olfactory cues may impede response inhibition, the results indicate that exposure to such stimuli may contribute to the activation of cognitive responses which may drive consumption.
尽管有充分的文献记载,与酒精相关的刺激和环境可能会引发与酒精相关的想法和行为,但酒精的气味如何影响这些想法和行为尚不清楚。
因此,本研究旨在调查视觉和嗅觉酒精线索对抑制控制的启动效应。
40名个体(年龄中位数=23.65,标准差=6.52)完成了一项“是/否”联想任务(GNAT),该任务在个体暴露于与酒精相关(或中性)的嗅觉和视觉线索时,测量反应时间、反应准确性和误报率。
与中性图片线索相比,与酒精相关的视觉线索引发的误报率更低、反应时间更慢、准确率更高。与暴露于中性嗅觉线索的人相比,暴露于酒精的人的误报率显著更高。
结果表明,暴露于与酒精相关的嗅觉线索可能会阻碍反应抑制,这凸显了暴露于此类刺激可能会导致认知反应的激活,进而可能推动饮酒行为。
