Abstract

Mindfulness meditation programs, which train individuals to monitor their present-moment experience in an open or accepting way, have been shown to reduce mind wandering on standardized tasks in several studies. Here we test 2 competing accounts for how mindfulness training reduces mind wandering, evaluating whether the attention-monitoring component of mindfulness training alone reduces mind wandering or whether the acceptance training component is necessary for reducing mind wandering. Healthy young adults (N = 147) were randomized to either a 3-day brief mindfulness training condition incorporating instruction in both attention monitoring and acceptance, a mindfulness training condition incorporating attention monitoring instruction only, a relaxation training condition, or an active reading-control condition. Participants completed measures of dispositional mindfulness and treatment expectancies before the training session on Day 1 and then completed a 6-min Sustained Attention to Response Task (SART) measuring mind wandering after the training session on Day 3. Acceptance training was important for reducing mind wandering, such that the attention-monitoring plus acceptance mindfulness training condition had the lowest mind wandering relative to the other conditions, including significantly lower mind wandering than the attention-monitoring only mindfulness training condition. In one of the first experimental mindfulness training dismantling studies to-date, we show that training in acceptance is a critical driver of mindfulness-training reductions in mind wandering. This effect suggests that acceptance skills may facilitate emotion regulation on boring and frustrating sustained attention tasks that foster mind wandering, such as the SART.

    Acceptance may support greater emotion regulation, buffering the distracting effects of negative emotions and aiding on-task attention and performance.

    “Specifically, attentionally demanding tasks can induce boredom, frustration and other unpleasant emotions that may interfere with task performance, while acceptance may facilitate greater emotion regulation that buffers the distracting effects of these negative emotions and facilitates on-task attention and performance (Lindsay & Creswell, 2015; Teper & Inzlicht, 2013).”

    In the attention-monitoring form of mindfulness, attention is focused on a stimulus object while meta-awareness monitors or regulates attention to sustain it.

    “For example, in the attention monitoring form of mindfulness commonly taught in mindfulness training programs, attention is concentrated upon a stimulus object (e.g., bodily sensations associated with breathing) while meta-awareness, an apprehension of the current state of the mind, serves to monitor or regulate attention in order to sustain it (Dreyfus, 2011).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
