摘要

正念训练(MT)已被证明有利于持续的注意力和走神。然而,很少有研究考察走神的个体差异是否会带来不同的益处。反应任务持续注意(SART)测量了1个月MT撤退前(T1)和(T2)后(n = 56)以及未接受MT的对照组(n = 32)参与者的任务准确性(A′)、反应时间变异(反应时间个体变异系数,ICV)和自我报告的走神。只有撤退组从T1到T2表现出A′增加和走神减少,但ICV没有变化。只有在考虑走神的个体差异时,静修参与者才表现出比对照组更低的ICV,这样,在T1时走神水平较高的静修参与者随着时间的推移表现出更大的ICV益处。这些发现表明,从客观和主观测量的变化来看,MT可能有利于持续注意力,考虑基线个体差异可能会增加我们对MT对持续注意力的好处的理解。

Does Intensive Mindfulness Training Strengthen Sustained Attention? Examining Individual Differences in Mind Wandering during the Sustained Attention to Response Task
Mindfulness training (MT) has been shown to benefit sustained attention and mind wandering. Yet, few studies have examined whether benefits differ as a function of individual differences in mind wandering. The sustained attention to response task (SART) measured task accuracy (A′), response time variability (response time intraindividual coefficient of variation, ICV), and self-reported mind wandering in participants before (T1) and after (T2) a 1-month MT retreat (n = 56), as well as in a control group (n = 32) who received no MT. Only the retreat group demonstrated increased A′ and reduced mind wandering, but no change in ICV, from T1 to T2. Retreat participants demonstrated reduced ICV compared to the control group only when considering individual differences in mind wandering such that retreat participants with higher levels of mind wandering at T1 demonstrated greater benefits to ICV over time. These findings suggest MT may benefit sustained attention, as seen in changes on both objective and subjective measures, and that considering baseline individual differences may increase our understanding of MT’s benefits to sustained attention.
