Meditation is an ancient practice that cultivates a calm yet focused mind; however, little is known about how short, practical meditation practices affect cognitive functioning in meditation-naïve populations. To address this question, we randomized subjects (ages of 18-45) who were non-experienced meditators into either a 13-min daily guided meditation session or a 13-min daily podcast listening session (control group) for a total duration of 8 weeks. We examined the effects of the daily meditation practice relative to podcast listening on mood, prefrontal and hippocampal functioning, baseline cortisol levels, and emotional regulation using the Trier Social Stress Test (TSST). Compared to our control group, we found that 8 but not 4 weeks of brief, daily meditation decreased negative mood state and enhanced attention, working memory, and recognition memory as well as decreased state anxiety scores on the TSST. Furthermore, we report that meditation-induced changes in emotional regulation are more strongly linked to improved affective state than improved cognition. This study not only suggests a lower limit for the duration of brief daily meditation needed to see significant benefits in non-experienced meditators, but suggests that even relatively short daily meditation practice can have similar behavioral effects as longer duration and higher-intensity mediation practices.
冥想是一种古老的修行方式,能培养出平静而专注的心态;然而,对于简短且实用的冥想练习如何影响从未接触过冥想的人群的认知功能,我们却知之甚少。为解决这个问题,我们将18至45岁、没有冥想经验的受试者随机分为两组,一组每天进行13分钟的引导式冥想练习,另一组每天听13分钟的播客(对照组),为期8周。我们使用特里尔社会应激测试(TSST),研究了每日冥想练习相对于听播客对情绪、前额叶和海马体功能、基线皮质醇水平以及情绪调节的影响。与对照组相比,我们发现,为期8周而非4周的简短每日冥想可降低负面情绪状态,增强注意力、工作记忆和识别记忆,并降低TSST中的状态焦虑得分。此外,我们报告称,冥想引起的情绪调节变化与改善的情感状态的关联比与改善的认知的关联更强。这项研究不仅表明了在没有冥想经验的人群中看到显著益处所需的每日简短冥想持续时间下限,还表明即使是相对较短的每日冥想练习也能产生与较长时间和高强度冥想练习类似的行为效果。
