In social contexts, the dynamic nature of others' emotions places unique demands on attention and emotion regulation. Mindfulness, characterized by heightened and receptive moment-to-moment attending, may be well-suited to meet these demands. In particular, mindfulness may support more effective cognitive control in social situations via efficient deployment of top-down attention. To test this, a randomized controlled study examined effects of mindfulness training (MT) on behavioral and neural (event-related potentials [ERPs]) responses during an emotional go/no-go task that tested cognitive control in the context of emotional facial expressions that tend to elicit approach or avoidance behavior. Participants (N = 66) were randomly assigned to four brief (20 min) MT sessions or to structurally equivalent book learning control sessions. Relative to the control group, MT led to improved discrimination of facial expressions, as indexed by d-prime, as well as more efficient cognitive control, as indexed by response time and accuracy, and particularly for those evidencing poorer discrimination and cognitive control at baseline. MT also produced better conflict monitoring of behavioral goal-prepotent response tendencies, as indexed by larger No-Go N200 ERP amplitudes, and particularly so for those with smaller No-Go amplitude at baseline. Overall, findings are consistent with MT's potential to enhance deployment of early top-down attention to better meet the unique cognitive and emotional demands of socioemotional contexts, particularly for those with greater opportunity for change. Findings also suggest that early top-down attention deployment could be a cognitive mechanism correspondent to the present-oriented attention commonly used to explain regulatory benefits of mindfulness more broadly.
在社交环境中,他人情绪的动态性质对注意力和情绪调节提出了独特的要求。正念以增强和接受瞬间的注意力为特征,可能非常适合满足这些要求。特别是,正念可以通过有效部署自上而下的注意力,为社交情境中的认知控制提供更有效的支持。为了验证这一点,一项随机对照研究考察了正念训练(MT)对情绪 Go/No-Go 任务中行为和神经(事件相关电位 [ERP])反应的影响,该任务在情绪面部表情的背景下测试了认知控制,这些表情往往会引发接近或回避行为。参与者(N=66)被随机分配到四个简短的(20 分钟)MT 课程或结构上等效的书籍学习对照组。与对照组相比,MT 提高了对面部表情的辨别力,表现为 d-prime 提高,以及认知控制的效率提高,表现为反应时间和准确性提高,尤其是那些基线时辨别力和认知控制较差的人。MT 还对行为目标优势反应倾向的冲突监测产生了更好的影响,表现为更大的 No-Go N200 ERP 振幅,特别是对于那些基线时 No-Go 振幅较小的人。总的来说,这些发现与 MT 增强早期自上而下注意力的分配能力,以更好地满足社会情感环境中独特的认知和情感需求的潜力一致,特别是对于那些有更大改变机会的人。研究结果还表明,早期自上而下注意力的分配可能是一种认知机制,与通常用于更广泛地解释正念调节益处的面向当下的注意力相对应。
