Prior research has linked mindfulness to improvements in attention, and suggested that the effects of mindfulness are particularly pronounced when individuals are cognitively depleted or stressed. Yet, no studies have tested whether mindfulness improves declarative awareness of unexpected stimuli in goal-directed tasks. Participants (N=794) were either depleted (or not) and subsequently underwent a brief mindfulness induction (or not). They then completed an inattentional blindness task during which an unexpected distractor appeared on the computer monitor. This task was used to assess declarative conscious awareness of the unexpected distractor's presence and the extent to which its perceptual properties were encoded. Mindfulness increased awareness of the unexpected distractor (i.e., reduced rates of inattentional blindness). Contrary to predictions, no mindfulness×depletion interaction emerged. Depletion however, increased perceptual encoding of the distractor. These results suggest that mindfulness may foster awareness of unexpected stimuli (i.e., reduce inattentional blindness).
先前的研究已将正念与注意力的改善联系起来,并表明当个体认知资源耗尽或处于压力状态时,正念的效果尤为显著。然而,尚无研究测试正念是否能提高目标导向任务中对意外刺激的陈述性意识。参与者(N = 794)被分为认知资源耗尽组(或非耗尽组),随后接受简短的正念训练(或不接受)。然后,他们完成一项无意视盲任务,在此期间,电脑屏幕上会出现一个意外的干扰物。该任务用于评估对意外干扰物出现的陈述性意识以及对其感知属性的编码程度。正念提高了对意外干扰物的意识(即降低了无意视盲率)。与预测相反,未出现正念×认知资源耗尽的交互作用。然而,认知资源耗尽增加了对干扰物的感知编码。这些结果表明,正念可能促进对意外刺激的意识(即减少无意视盲)。
