Abstract

Participants completed two sessions of an auditory attention task and intermittently responded to thought probes asking about their level of mind-wandering. After the first session one group received 200 mg of caffeinated chewing gum (n = 61) and another group received regular (placebo) chewing gum (n = 66). The gum was chewed for 20-minutes and then disposed of before beginning the second session. Participants who received caffeine showed a performance benefit as well as reported being more on task and fewer instances of spontaneous mind-wandering compared to those in the placebo group. Participants who received caffeine also reported greater positive affect and arousal, as well as less feelings of boredom, sleepiness, and mental effort required to stay on task compared to those who received placebo. These results suggest that caffeine may benefit attentional engagement as well as performance during a sustained attention task.

研究咖啡因对听觉注意力任务的影响。

受试者完成了两节听觉注意力任务，并间歇性地回答了询问其思维游离程度的思维探究。在第一个环节结束后，一组接受 200 毫克含咖啡因的口香糖（n = 61），另一组接受普通（安慰剂）口香糖（n = 66）。口香糖咀嚼 20 分钟后，在开始第二个疗程前将其丢弃。与安慰剂组相比，摄入咖啡因的受试者表现得更专注于任务，自发胡思乱想的情况也更少。与服用安慰剂的人相比，服用咖啡因的人还报告说，他们的积极情绪和觉醒度更高，无聊感、困倦感和完成任务所需的脑力劳动也更少。这些结果表明，咖啡因可能有益于注意力的投入以及在持续注意力任务中的表现。
