自发走神和有意走神及其与元认知的关系

走神包括有意走神和自发走神两种类型,元认知对二者的影响可能不同。研究使用两维度走神量表和元认知-30量表,对国内部分高校学生的走神和元认知(元认知信念、元认知加工和认知自信判断)进行调查,结果显示:(1)走神可以划分为有意走神和自发走神;(2)失控和危险感既能预测自发走神也能预测有意走神,但认知自信只能预测自发走神,认知的自我意识只能预测有意走神。说明元认知对自发走神和有意走神的影响存在差异。     

Positive and negative mind wandering: an assessment of their relationship with mindfulness and metacognition in university students / Divagación mental positiva y negativa: evaluando su relación con la atención plena y la metacognición en estudiantes universitarios

Abstract

This article reports the results of an initial study whose purpose was to create a mind wandering scale in Spanish through documenting evidence of its validity. Then, it presents the results of a second study that develops correlation and regression analysis on the relationship between positive and negative mind wandering, mindfulness, metacognition and frequency of daydreaming. Positive mind wandering has a positive correlation with all the mindfulness facets and metacognition scales, with the exception of the Academic Difficulties scale. Negative mind wandering has a negative correlation with all the mindfulness facets and metacognition scales, with two exceptions: Observing, which is uncorrelated with Negative Mind Wandering, and Academic Difficulties, which correlates positively. Likewise, the study allowed a preliminary identification of how positive and negative mind wandering — as well as facets of mindfulness — predict different metacognition scales. Upon examination of interaction effects, three significant — negative — effects were detected between positive mind wandering and the frequency of daydreaming when predicting (i) Independent Thinking, (ii) Academic Self-efficacy and (iii) Metacognitive Strategies. This suggests that, for these three response variables, the positive effects associated with positive mind wandering decrease as the frequency of daydreaming increases.     

Investigating the relationship between bilingualism,cognitive control,and mind wandering

Some research has suggested that bilingualism produces cognitive control advantages, although it has recently been shown that reported advantages are influenced by a publication bias. If the bilingual (BL) advantage does exist, the specific causes and contexts for its appearance remain unclear. The purpose of the current study was twofold: one, to examine performance of BLs and monolinguals (MLs) on a variety of simple versus complex cognitive control tasks; and two, to determine whether there were language group differences in the tendency to mind wander, which has been heavily implicated in cognitive control tasks. Although we hypothesised that if BLs outperformed MLs on cognitive control tasks, this would be associated with less mind wandering for BLs, the results did not reveal any BL advantages or any differences in mind-wandering tendencies. These findings support calls to temper BL advantage claims and shows a need for future research to better specify which underlying factors of cognitive control may be optimised by multilingualism.     

心智游移的研究：理论、方法及进展

心智游移普遍存在于个体的意识体验中,主要指自发产生的、与当前外界环境无关的思维加工。目前,有关心智游移的理论在其与执行控制的关系上存在争议,主要有心智游移的执行控制理论、控制失败假说和全局可用性假说等。当前的研究主要基于口头报告,并辅以问卷和量表,一些客观指标和认知神经科学的方法也正尝试着对它进行探究。采用这些方法,心智游移的研究已取得了很大的进展。在行为水平上,相关研究探讨了它的时间属性、与元意识的关系、不同因素对它的作用以及它对认知加工的影响等;在认知神经水平上,默认网络与心智游移的关系备受关注,对心智游移时脑电成分的研究也有助于对其机制的了解。未来的研究在心智游移的产生机制、功能和研究方法上可以有进一步的发展。     

Understanding the role of mind wandering in stress-related working memory impairments

Mind wandering has been identified as a possible cause for stress-related working memory (WM) task impairments following laboratory stressors. The current study attempted to induce mind wandering regarding negative, positive, or neutral events using an expressive writing task and examined the impact on WM task performance. We examined the role of mind wandering in understanding the impact of life stress on WM. Additionally, we explored the role of thought suppression on the relationship between mind wandering and WM. One hundred and fifty participants completed WM measures before (Time 1) and after (Time 2) the writing manipulation. The writing manipulation did not alter mind wandering or WM task performance. Time 1 WM predicted mind wandering during the Time 2 WM task, which subsequently predicted poorer Time 2 WM task performance. The impact of daily life stress on WM was mediated by mind wandering. Trait levels of thought suppression moderated the impact of mind wandering on WM. Specifically, higher levels of suppression resulted in stronger negative impact of mind wandering on WM task performance. Findings are discussed in terms of the impact of mind wandering on WM task performance.     

Phenomenal consciousness in dreams and in mind wandering

Dreaming can be explained as the product of an interaction among memory processes, elaborative processes, and phenomenal awareness. A feedback circuit is activated by this interaction according to the associative links and the requirements of the dream scene. Recently, it has been hypothesized that a partial similarity exists between dreaming and mind wandering and that these two processes may involve the same neural default network. This commentary discusses the differences and similarities between phenomenal consciousness during dreaming and phenomenal consciousness during mind wandering from the perspective of the “continuity” of engagement of cognitive systems. The greatest difference consists in the lack of reality testing during dreaming. Dream imagery is hallucinatory by nature. Consequently, the simulated world in dreams makes dream imagery more akin to perception. In contrast, the imagery of mind wandering is more similar to imagination. The level of meta-awareness is preserved more frequently and to a greater degree in mind wandering.     

A Wandering Mind is Not Always a Creative Mind: How Thought Dynamics Explain the Relationship between Mind Wandering and Creativity

A wandering mind is not always a creative mind. Anecdotes about ideas spontaneously entering awareness during walks, showers, and other off-task activities are plenty. The science behind it, however, is still inconclusive. Creativity might result from how thought context—whether thoughts are on-task or off-task—relates to thought dynamics—how thoughts unfold. To explore this, study 1 (n = 85) surveyed creative professionals about a single idea they had earlier in the day. The spontaneity of thoughts positively correlated with self-reported creativity, whereas off-task thoughts or doing something else did not. Study 2 (n = 180) replicated these findings in a student sample during an idea generation task and added that free movement of thoughts also correlates with self-reported originality during idea generation. As indicated by expert ratings, no relationship of thought dynamics and thought context was found with population-level creativity. Herewith, this study suggests that thought dynamics, rather than thought context, explain the often suggested relationship between mind wandering and creativity.     

毅力与学业成绩的关系：有意走神和自发走神的不同中介作用

以3372名5年级小学生为研究对象,采用毅力量表、有意走神和自发走神量表以及学业成绩测验,考察毅力（兴趣一致性和坚持努力）对学业成绩的影响,并检验有意走神和自发走神的中介作用。结果发现：（1）兴趣一致性和坚持努力均显著正向预测学业成绩;（2）有意走神、自发走神在兴趣一致性和坚持努力与学业成绩之间均起显著的中介作用,但两者的中介作用模式存在差异。有意走神在兴趣一致性和坚持努力与学业成绩间的中介作用不同：兴趣一致性负向影响有意走神,有意走神正向影响学业成绩,坚持努力正向影响有意走神,有意走神正向影响学业成绩;而自发走神在兴趣一致性和坚持努力对学业成绩预测的中介作用相同,即兴趣一致性和坚持努力均负向影响自发走神,自发走神负向影响学业成绩。     

阅读中的“心不在焉”:理论假设和影响因素

人们在阅读时,思维有时会游离到所读内容之外,此时人们的目光虽然还在沿着所读材料移动,但认知加工却游离到一些与任务无关的内容上,这就是所谓阅读中的"心不在焉"。本文总结归纳了阅读中"心不在焉"的三个主要理论假设:执行控制理论、控制失败假说和注意解离假说。分析了阅读中"心不在焉"的三种影响因素:第一,阅读方式,即被试采取朗读或默读的阅读方式以及阅读时是否有时间限制等;第二,阅读材料,即材料难度、阅读兴趣与词汇特征;第三,被试的年龄、元觉察能力和工作记忆容量。最后提出了一些目前阅读中的"心不在焉"研究中存在的问题和未来可能的研究方向,为后续的研究提供一定的启发和借鉴。     

A wandering mind is a less caring mind: Daily experience sampling during compassion meditation training

Mind wandering, or the tendency for attention to drift to task-irrelevant thoughts, has been associated with worse intra- and inter-personal functioning. Utilizing daily experience sampling with 51 adults during 9-weeks of a compassion meditation program, we examined effects on mind wandering (to neutral, pleasant, and unpleasant topics) and caring behaviors for oneself and others. Results indicated that compassion meditation decreased mind wandering to neutral topics and increased caring behaviors towards oneself. When collapsing across topics, mind wandering did not serve as an intermediary between the frequency of compassion meditation practice and caring behaviors, though mind wandering to pleasant and unpleasant topics was linked to both variables. A path analysis revealed that greater frequency of compassion meditation practice was related to reductions in mind wandering to unpleasant topics and increases in mind wandering to pleasant topics, both of which were related to increases in caring behaviors for oneself and others.

Wandering eyes: Eye movements during mind wandering in video lectures

Video lectures are increasingly prevalent, but they present challenges to learners. Students' minds often wander, yet we know little about how mind wandering affects attention during video lectures. This paper presents two studies that examined eye movement patterns of mind wandering during video lectures. In the studies, mind wandering reports were collected by either self-caught reports or thought probes. Results were similar across the studies: mind wandering was associated with an increased allocation of fixations to the instructor's image. For fixations on the slides, the average duration increased but the dispersion decreased. Moreover, preliminary evidence suggested that fixation duration and dispersion can diminish soon after self-caught reports of mind wandering. Overall, these findings help advance our understanding of how learners' attention is affected during mind wandering and may facilitate efforts in objectively identifying mind wandering. Future research is needed to determine if these findings can extend to other instructional formats.     

智能手机成瘾者的注意执行控制功能:心智游移的作用

智能手机成瘾可能会影响个体的注意执行控制功能,以往研究结果在该影响是否取决于实验刺激与成瘾物的相关性上存在不一致,研究关注心智游移在其中的作用。采取《大学生智能手机成瘾量表》筛选被试90人分为成瘾组和非成瘾组。实验一采用反应的持续注意任务考察不同水平智能手机成瘾者的心智游移特点,采用《白日梦量表》辅助研究,结果发现智能手机成瘾被试量表得分显著更高,在实验中更多地评估任务表现,且其心智游移与偶然性的任务疏忽、一般性任务疏忽以及反应分离状态有关。实验二采用AX版本的持续操作任务探究智能手机成瘾者的注意执行控制功能中心智游移的调节作用,结果发现高频心智游移的智能手机成瘾者比低频心智游移的智能手机成瘾者维持目标更困难。研究对于理解智能手机成瘾对个体认知的影响具有一定的启示作用。

Positive post‐disaster images: A daydream machine?

This study explores the impact of post‐earthquake images inserted in a vigilance task, in terms of performance, self‐reports of task‐focus, and cerebral activity using functional near‐infrared spectroscopy (fNIRS). Vigilance tasks present a sequence of stimuli in which only a few are pre‐designated critical or target stimuli requiring an overt response from the participant. Seventy‐one residents participated (51 women, 20 men) by taking part in a vigilance task with task‐irrelevant images inserted in the sequence. There were three conditions consisting positive (emotive inducing), negative (emotive inducing), and control (devoid of meaning) images embedded in the vigilance task to assess possible impacts on vigilance performance. The images were obtained through crowdsourcing and represented parts of the city 3–4 years post‐earthquake. Task performance was assessed with signal detection theory metrics of sensitivity A’ and bias β’’. This enables the separation of an individual's ability to accurately discriminate critical signals from non‐critical stimuli (sensitivity) and shifts in their willingness to respond to any stimuli whether critical or not (bias). Individuals viewing the positive images, relating to progress, rebuild, or aesthetic aspects within the city, had a more conservative response bias (they responded less to both rare critical and distractor stimuli) than those in the other conditions. These individuals also reported lower task‐focus, as would be expected. However, contrary to expectations, indicators of cerebral activity (fNIRS) did not differ significantly between the experimental groups. These results, when combined, suggest that mind wandering events may be being generated when exposed to positive post‐earthquake images.     

The prevalence of cognitive disengagement in automobile crashes

The current study analysed crashes identified in a large-scale naturalistic driving database to assess the prevalence of cognitive disengagement (i.e., purely cognitive distraction and mind wandering/microsleep) or episodes wherein the driver did not look away from the roadway during secondary task completion or wherein another clearly observable contributing crash factor was not present, and the driver's reaction to the crash showed symptoms of cognitive disengagement. The study found that <1% (95% CI [0.45, 1.66]) of higher severity crashes had a potential contributing crash factor of mind wandering/microsleep; ~1.5% (95% CI [0.83, 2.32]) had a potential contributing factor of purely cognitive distraction. The results suggest a relatively low prevalence of cognitive disengagement among automotive crashes compared with visual/manual secondary tasks. However, the current methodology is limited in that it does not account for instances where cognitive disengagement, in combination with other factors, may have led to crashes, potentially leading to conservative estimates.
