The objective of the current study was to investigate the effect of a brief mindfulness practice on perceived stress and sustained attention, and to determine whether priming the benefits of mindfulness meditation enhances this effect.
Two hundred and twenty undergraduate students were randomly assigned to a control condition (CC), a meditation condition (MC), or a priming + meditation condition (PMC). Baseline and post-treatment measures included subjective stress ratings on a visual analog scale (VAS) and performance on a Sustained Attention to Response Task (SART), determined by reaction time coefficient of variability (RTCV) and three measures of accuracy: correct responses, errors of commission, and errors of omission.
Repeated measures analyses revealed that both the MC and the PMC displayed a decline in perceived stress relative to the CC. Analyses further revelated that the MC and PMC displayed fewer errors of omission relative to the CC. However, only the PMC displayed better performance relative to the CC with respect to total correct response and errors of commission. There were no significant between-group differences for RTCV.
These findings are novel and provide a foundation to further investigate the effect of priming on mindfulness engagement and its potential benefits.

本研究的目的是调查简短的正念练习对感知压力和持续注意力的影响，并确定启动正念冥想的益处是否会增强这种效果。
220名本科生被随机分配到对照条件组（CC）、冥想条件组（MC）或启动+冥想条件组（PMC）。基线和治疗后测量包括视觉模拟量表（VAS）上的主观压力评分以及持续注意力反应任务（SART）的表现，通过反应时间变异系数（RTCV）和三项准确性测量指标来确定：正确反应、误判错误和漏判错误。
重复测量分析显示，相对于CC组，MC组和PMC组的感知压力均有所下降。进一步分析表明，相对于CC组，MC组和PMC组的漏判错误更少。然而，仅PMC组在总正确反应和误判错误方面相对于CC组表现更好。RTCV在组间没有显著差异。
这些发现是新颖的，并为进一步研究启动对正念参与及其潜在益处的影响提供了基础。
