    背景:手卫生本科培训是感染控制的基石。几项研究表明,过度自信在手卫生习惯中的影响,这会损害元认知。我们假设过度自信可能在护理专业学生的早期教育阶段普遍存在,并且可以通过频繁的交互式学习形式来减少这些影响。比如学习小组。
    方法:我们对196名德国护理专业学生进行了多中心横断面调查问卷,包括一般,外科,和麻醉护理专业。
    结果:在所有专业和教育年限的护理专业学生中都观察到过度自信。聚类分析显示了三种不同类型的学习者:两种以过度自信为特征,一种表现出合理的自信。此外,适度分析表明,提供反馈和促进关于学生学习成就的元认知可以减轻过度安置,特别是通过互动教学形式的频繁实施。
    结论:尽管有一些限制,这些发现突出了护理专业学生过度自信效应的普遍性,存在不同的学习概况,以及将反馈纳入有关手部卫生的交互式学习格式的重要性。因此,教育工作者需要接受培训和监督,以提供这些学习格式,并有效地向学生提供反馈。
    BACKGROUND: Undergraduate training in hand hygiene is a keystone of infection control. Several studies have shown overconfidence effects in hand hygiene practices, which can impair metacognition. We hypothesized that overconfidence might be prevalent in the early education stages of nursing students and that these effects could be reduced through frequent interactive learning formats, such as learning groups.
    METHODS: We conducted a multicenter cross-sectional questionnaire with 196 German nursing students, including general, surgical, and anesthetic nursing specializations.
    RESULTS: Overconfidence was observed in nursing students across all specialties and years of education. The cluster analyses showed three different types of learners: two characterized by overconfidence and one demonstrating justifiable confidence. Furthermore, the moderation analysis indicated that providing feedback and promoting metacognition regarding students\' learning achievements could mitigate overplacement, particularly through the frequent implementation of interactive teaching formats.
    CONCLUSIONS: Despite some limitations, these findings highlight the prevalence of overconfidence effects in nursing students, the presence of different learning profiles, and the importance of incorporating feedback within interactive learning formats concerning hand hygiene. Accordingly, educators need to be trained and supervised to deliver these learning formats and provide feedback to students effectively.

    学生对回答问题的信心如何具有重要的教育意义。参与者回答了10个数学问题,并提供了他们对每个项目正确的可能性以及正确的数量的估计,总的来说,他们回答正确。他们对这些元认知判断过于自信。一些参与者被要求在做出这些判断之前证明为什么他们的答案是正确的或不正确的。这降低了他们的信心评级。他们仍然过于自信,但低于对照组。该指令还影响了置信度等级和准确度之间的关联。在那些被要求证明他们的回答是正确的人与那些被要求证明他们的回答是不正确的人之间没有观察到差异。那些被要求考虑回应准确性的人信心较低。这对于理解我们如何构建信心判断以及在教育中如何在评估过程中影响学生的信心具有重要意义。
    How confident a student is about how they answer a question has important education implications. Participants answered 10 mathematics questions and provided their estimates of how likely they got each individual item correct and how many, in total, they answered correctly. They were overconfident in these metacognitive judgments. Some of the participants were asked to justify why their answers were either correct or incorrect prior to making these judgments. This lowered their confidence ratings. They were still overconfident, but less than those in the control group. The instruction also affected the association between the confidence ratings and accuracy. No differences were observed between those asked to justify why their responses were correct versus those asked to justify why their responses were incorrect. Those asked to think about the accuracy of a response had lower confidence. This has important implications for understanding how we construct confidence judgments and within education how student confidence can be affected during assessments.

    观察者可以区分正确和不正确的感知决定与自信的感觉。中心顶叶阳性建立率(CPP斜率)已被认为是累积证据的可能的神经特征,这可以指导感知表现和信心。然而,CPP斜率也随反应时间变化,这也与以前研究的信心一致,绩效和信心通常是互变的;因此,CPP斜率可以索引感知性能的签名,而不是置信度本身。此外,知觉元认知-包括神经相关因素-已经在视觉中进行了大量研究,除了少数例外。因此,我们缺乏对视觉外感知元认知的领域-一般神经签名的理解。在这里,我们设计了一种新颖的听觉音高识别任务,并在健康成年人中同时收集32通道EEG的行为。参与者在每次试验中看到两个音调标签,它们的音调距离各不相同(例如,CvsD,CvsF),然后听到一个单一的听觉音调;他们确定哪个标签是正确的,并评定置信度。我们发现音调识别置信度随音调距离而变化,但是性能,元认知敏感性(信心与准确性的逐个试验协变),反应时间没有。有趣的是,然而,而CPP斜率与性能和反应时间相关,它与信心没有显著的相关性.我们将这些结果解释为意味着CPP斜率可能是一阶感知处理的特征,而不是听觉任务中的置信度特定信号或计算。我们新颖的音高识别任务提供了一种有价值的方法来检查听觉和域一般感知置信度的神经相关性。
    Observers can discriminate between correct versus incorrect perceptual decisions with feelings of confidence. The centro-parietal positivity build-up rate (CPP slope) has been suggested as a likely neural signature of accumulated evidence, which may guide both perceptual performance and confidence. However, CPP slope also covaries with reaction time, which also covaries with confidence in previous studies, and performance and confidence typically covary; thus, CPP slope may index signatures of perceptual performance rather than confidence per se. Moreover, perceptual metacognition-including neural correlates-has largely been studied in vision, with few exceptions. Thus, we lack understanding of domain-general neural signatures of perceptual metacognition outside vision. Here we designed a novel auditory pitch identification task and collected behavior with simultaneous 32-channel EEG in healthy adults. Participants saw two tone labels which varied in tonal distance on each trial (e.g., C vs D, C vs F), then heard a single auditory tone; they identified which label was correct and rated confidence. We found that pitch identification confidence varied with tonal distance, but performance, metacognitive sensitivity (trial-by-trial covariation of confidence with accuracy), and reaction time did not. Interestingly, however, while CPP slope covaried with performance and reaction time, it did not significantly covary with confidence. We interpret these results to mean that CPP slope is likely a signature of first-order perceptual processing and not confidence-specific signals or computations in auditory tasks. Our novel pitch identification task offers a valuable method to examine the neural correlates of auditory and domain-general perceptual confidence.

    神经性厌食症(AN)患者通常对自己的身体持有改变的信念,他们很难更新,包括全球,关于他们了解和调节身体的能力,特别是他们的相互感受状态的前瞻性信念。虽然临床问卷调查研究提供了充分的证据证明这种信念在发病中的作用,维护,和AN的治疗,心理物理学研究通常集中在感知和“局部”信念上。在两个实验中,我们检查了急性AN(N=86)和急性后AN状态(N=87)的女性,与匹配的健康对照组(N=180)相比,在适应性心跳计数任务中形成并更新了他们的自我效能感信念(实验1)和前瞻性(实验2)。如预注册,虽然AN患者在感觉准确性方面与对照组没有差异,他们持有并保持“悲观”的内在联系,表现后的元认知自我效能感信念。使用简化的计算贝叶斯学习框架进行建模表明,没有来自性能的局部证据,也不是在表现之后的回顾性信念(本身是次优更新的)似乎足以对抗和更新悲观的,AN中的自我效能感信念。患者的学习率低于对照组,揭示了在回顾性和前瞻性信念更新中更多地基于先前信念而不是预测错误的趋势。进一步的探索表明,虽然两种明确信念的这些差异,以及信念更新的潜在机制,不能用一般的认知灵活性差异来解释,他们被解释为负面情绪合并症,即使在疾病的急性期之后。
    Patients with anorexia nervosa (AN) typically hold altered beliefs about their body that they struggle to update, including global, prospective beliefs about their ability to know and regulate their body and particularly their interoceptive states. While clinical questionnaire studies have provided ample evidence on the role of such beliefs in the onset, maintenance, and treatment of AN, psychophysical studies have typically focused on perceptual and \'local\' beliefs. Across two experiments, we examined how women at the acute AN (N = 86) and post-acute AN state (N = 87), compared to matched healthy controls (N = 180) formed and updated their self-efficacy beliefs retrospectively (Experiment 1) and prospectively (Experiment 2) about their heartbeat counting abilities in an adapted heartbeat counting task. As preregistered, while AN patients did not differ from controls in interoceptive accuracy per se, they hold and maintain \'pessimistic\' interoceptive, metacognitive self-efficacy beliefs after performance. Modelling using a simplified computational Bayesian learning framework showed that neither local evidence from performance, nor retrospective beliefs following that performance (that themselves were suboptimally updated) seem to be sufficient to counter and update pessimistic, self-efficacy beliefs in AN. AN patients showed lower learning rates than controls, revealing a tendency to base their posterior beliefs more on prior beliefs rather than prediction errors in both retrospective and prospective belief updating. Further explorations showed that while these differences in both explicit beliefs, and the latent mechanisms of belief updating, were not explained by general cognitive flexibility differences, they were explained by negative mood comorbidity, even after the acute stage of illness.

    元认知偏见反复与“焦虑抑郁”和“强迫性和侵入性思维”的诊断性精神病学维度相关,横截面。为了提高我们对潜在神经认知机制的理解,需要新的方法来远程测量元认知,个人随着时间的推移。我们开发了一个游戏化的智能手机任务,旨在测量视觉感知元认知(信心)偏差,并在两项研究中调查了其心理测量特性(N=3410无薪公民科学家,N=52名付费参与者)。我们评估了收敛有效性,半分割和重测可靠性,并确定了捕获其临床相关性所需的最小试验数量。元认知偏倚的收敛效度是中等的(r(50)=0.64,p<0.001),并且表现出出色的分半信度(r(50)=0.91,p<0.001)。焦虑抑郁与信心下降相关(β=-0.23,SE=0.02,p<0.001),而强迫性和侵入性思维与更高的置信度相关(β=0.07,SE=0.02,p<0.001)。仅在40项试验中,就可以明显看出元认知偏见与诊断性精神病学维度之间的关联。决策中的元认知偏差在会话内和会话之间是稳定的,对于100个试验(ICC=0.86,N=110)和40个试验(ICC=0.86,N=120)版本的MetaMind,表现出非常高的重测可靠性。混合“自我报告认知”任务可能是弥合最近讨论的计算精神病学可靠性差距的一种方法。
    Metacognitive biases have been repeatedly associated with transdiagnostic psychiatric dimensions of \'anxious-depression\' and \'compulsivity and intrusive thought\', cross-sectionally. To progress our understanding of the underlying neurocognitive mechanisms, new methods are required to measure metacognition remotely, within individuals over time. We developed a gamified smartphone task designed to measure visuo-perceptual metacognitive (confidence) bias and investigated its psychometric properties across two studies (N = 3410 unpaid citizen scientists, N = 52 paid participants). We assessed convergent validity, split-half and test-retest reliability, and identified the minimum number of trials required to capture its clinical correlates. Convergent validity of metacognitive bias was moderate (r(50) = 0.64, p < 0.001) and it demonstrated excellent split-half reliability (r(50) = 0.91, p < 0.001). Anxious-depression was associated with decreased confidence (β =  - 0.23, SE = 0.02, p < 0.001), while compulsivity and intrusive thought was associated with greater confidence (β = 0.07, SE = 0.02, p < 0.001). The associations between metacognitive biases and transdiagnostic psychiatry dimensions are evident in as few as 40 trials. Metacognitive biases in decision-making are stable within and across sessions, exhibiting very high test-retest reliability for the 100-trial (ICC = 0.86, N = 110) and 40-trial (ICC = 0.86, N = 120) versions of Meta Mind. Hybrid \'self-report cognition\' tasks may be one way to bridge the recently discussed reliability gap in computational psychiatry.

    先前的研究表明,各种因素,比如心理困扰,不容忍痛苦,快感缺失,冲动和吸烟元认知,单独与吸烟的冲动联系在一起,戒断症状和依赖性。然而,尚未对这些因素进行共同检查,以确定吸烟元认知是否独立且显著地影响这些结局.因此,这项研究的目的是调查痛苦不耐受的影响,快感缺失,对吸烟冲动的冲动和吸烟元认知,依赖吸烟的男性的戒断症状和依赖性。共有300名依赖吸烟的男性完成了心理量表和与吸烟相关的措施。研究结果表明,关于情绪调节的积极元认知显著预测了吸烟的冲动,即使考虑到其他重要的预测因素,如每天吸烟的数量,心理困扰,快感和冲动。此外,关于认知调节的积极元认知被发现是戒断症状的重要预测因子,独立于其他重要的预测因素,如心理困扰和吸烟的冲动。吸烟依赖是通过对不可控性的负面元认知来预测的,超过了其他重要的预测因素,包括每天吸烟和不耐受的香烟数量。这些结果强调了关于吸烟的元认知在与吸烟相关的短期和长期临床结果中的作用。因此,在吸烟依赖治疗期间解决这些信念应该是一个重要的治疗目标。
    Previous research has indicated that various factors, such as psychological distress, distress intolerance, anhedonia, impulsivity and smoking metacognitions, have been individually linked to the urge to smoke, withdrawal symptoms and dependence. However, these factors have not been collectively examined to determine whether smoking metacognitions independently and significantly contribute to these outcomes. Therefore, the aim of this study was to investigate the impact of distress intolerance, anhedonia, impulsivity and smoking metacognitions on the urge to smoke, withdrawal symptoms and dependency in men who are dependent on smoking. A total of 300 smoking-dependent men completed psychological scales and smoking-related measures. The findings of the study indicated that positive metacognitions about emotion regulation significantly predicted the urge to smoke, even when accounting for other significant predictors such as the number of daily cigarettes smoked, psychological distress, anhedonia and impulsivity. Furthermore, positive metacognitions about cognitive regulation were found to be a significant predictor of withdrawal symptoms, independent of other significant predictors such as psychological distress and the urge to smoke. Smoking dependence was predicted by negative metacognitions about uncontrollability beyond other significant predictors, including the number of daily cigarettes smoked and distress intolerance. These results highlight the role of metacognitions about smoking in both short- and long-term clinical outcomes related to smoking. Consequently, addressing such beliefs during treatment for smoking dependence should be an important therapeutic goal.

    了解疾病和抑郁症状的理论机制之间的人内差异可以帮助确定干预目标。抑郁症的认知模型假设功能失调的态度是潜在的脆弱性因素,而元认知模型强调功能失调的元认知信念。然而,以前没有研究测试过功能失调态度和元认知信念的变化作为个体抑郁症状变化的预测因子的相对重要性.在间隔5周的四个时间点测量的1,418个个体的样本中,多水平模型方法被用来检验功能失调态度和元认知信念的变化作为抑郁症状变化预测因子的相对重要性.功能失调态度和元认知信念的变化可预测抑郁症状的变化。然而,与功能失调的态度相比,元认知信念的变化,尤其是负元认知信念和认知信心的判断是抑郁症状变化的更强预测因子。此外,元认知信念的变化可以预测功能失调态度的变化,而不是抑郁症状的变化。这些结果表明,随着时间的推移,元认知信念而不是功能失调的态度对于人体内的抑郁症状可能更为重要,并且元认知变化也可能随着时间的推移影响功能失调的态度。因此,元认知信念是旨在减少抑郁症状的治疗和预防的有希望的目标,但在得出更明确的结论之前,我们的结果必须在临床样本中复制。
    Understanding within-person variation between theorized mechanisms of disorder and depressive symptoms can help identify targets for interventions. Cognitive models of depression hypothesize dysfunctional attitudes as underlying vulnerability factors, while the metacognitive model places emphasis on dysfunctional metacognitive beliefs. However, no previous study has tested the relative importance of change in dysfunctional attitudes and metacognitive beliefs as predictors of change in depressive symptoms within individuals. In a sample of 1,418 individuals measured at four time-points separated by 5-week intervals, a multilevel model approach was used to test the relative importance of change in dysfunctional attitudes and metacognitive beliefs as predictors of change in depressive symptoms. Change in dysfunctional attitudes and metacognitive beliefs predicted change in depressive symptoms over time. However, change in metacognitive beliefs and in particular negative metacognitive beliefs and judgements of cognitive confidence were significantly stronger predictors of change in depressive symptoms compared to dysfunctional attitudes. Furthermore, change in metacognitive beliefs predicted change in dysfunctional attitudes beyond change in depressive symptoms. These results suggest that metacognitive beliefs rather than dysfunctional attitudes might be more important for depressive symptoms over time within persons and that metacognitive change may also influence dysfunctional attitudes over time. Metacognitive beliefs are therefore a promising target for treatment and prevention aiming to reduce depressive symptoms, but replication of our results in clinical samples is warranted before more clear conclusions can be drawn.

    背景:饮食失调的危险因素是多方面和复杂的,因此,阐明执行职能的作用至关重要,包括冲动性和元认知,以及饮食行为严重程度的应对策略。这项研究的目的有三个:(1)分析冲动的性别差异,元认知,应对策略,情绪调节,和进食障碍;(2)检验研究变量之间的相关性;(3)检验应对和情绪调节策略在元认知关系中的中介作用,冲动,和饮食失调。
    方法:共有1076名参与者(Mage=21.78,SD=5.10;77.7%的女性)完成了一组问卷。进行了两次中介分析,以测试应对策略的中介作用,包括情绪调节,在执行功能之间的关系中(即,冲动和元认知)和饮食失调。
    结果:女性表现出更高的应对策略,特别是情感表达,一厢情愿的想法,社会支持,而男性表现出更大的社会退缩。中介分析表明,冲动,元认知,和饮食失调,其关系部分由应对策略介导,主要由情绪调节。
    结论:基于应对策略和情绪调节的干预措施可能是应对年轻人饮食失调的可行且有效的选择。
    BACKGROUND: Risk factors for eating disorders are multifaceted and complex, so it is crucial to elucidate the role of executive functions, including impulsivity and metacognition, and coping strategies in the severity of eating behaviors. The study aims were threefold: (1) to analyze gender differences in impulsivity, metacognition, coping strategies, emotion regulation, and eating disorders; (2) to examine the correlation between the study variables; and (3) to test the mediating role of coping and emotion-regulation strategies in the relationship between metacognition, impulsivity, and eating disorders.
    METHODS: A total of 1076 participants (Mage = 21.78, SD = 5.10; 77.7% women) completed a set of questionnaires. Two mediation analyses were conducted to test the mediating role of coping strategies, including emotion regulation, in the relationship between executive functions (i.e., impulsivity and metacognition) and eating disorders.
    RESULTS: Women displayed higher coping strategies, specifically emotional expression, wishful thinking, and social support, whereas men presented greater social withdrawal. Mediational analyses showed a significant association between impulsivity, metacognition, and eating disorders, whose relationship was partially mediated by coping strategies and mainly by emotion regulation.
    CONCLUSIONS: Interventions based on coping strategies and emotion regulation could be a feasible and effective option to deal with eating disorders among the young population.

    对觉醒后继续影响做梦者思想和感受的梦的分类研究区分了三种类型的有影响力的梦:噩梦,存在的梦想,和超越的梦想。其中,存在的梦和超越的梦的特征是对互补(a)隐喻(A\“is\”B)断言和(b)字面(A\“is\”B)断言之间的认知张力的反复元认知评价。这种互补的隐喻和字面断言的元认知评估可以被视为无法表达的实现感。这种无法表达的实现的诗意取决于隐喻主题和载体的并置,它们都是“语义密集”,但彼此处于抽象水平“遥远”。结果是隐喻工具的属性的“出现”,这些属性足够抽象,也可以成为隐喻主题的属性。连续的隐喻/字面分类转换的累积效应产生了更高级别的元认知形式,这与新康德对崇高感觉的解释一致。崇高的感觉发生为崇高的不平静(存在的梦想)或崇高的迷恋(超越的梦想)。这两种梦想类型的后果是主题迭代的“生活隐喻”,具有抽象的(但不是“总计”)本体论意义。
    Taxonomic studies of dreams that continue to influence the dreamer\'s thoughts and feelings after awakening have distinguished three types of impactful dreams: nightmares, existential dreams, and transcendent dreams. Of these, existential dreams and transcendent dreams are characterized by recurrent metacognitive appraisal of the epistemic tension between complementary (a) metaphoric (A \"is\" B) assertions and (b) literal (A \"is not\" B) assertions. Metacognitive appraisal of such complementary metaphoric and literal assertions is detectable as the felt sense of inexpressible realizations. The poesy of such inexpressible realizations depends upon the juxtaposition of a metaphoric topic and vehicle that are both \"semantically dense\" but at an abstract level \"distant\" from each other. The result is \"emergence\" of attributes of the metaphoric vehicle that are sufficiently abstract to be attributes also of the metaphoric topic. The cumulative effect of successive metaphoric/literal categorical transformations produces a higher-level form of metacognition that is consistent with a neo-Kantian account of sublime feeling. Sublime feeling occurs as either sublime disquietude (existential dreams) or as sublime enthrallment (transcendent dreams). The aftereffects of these two dream types are thematically iterative \"living metaphors\" that have abstract (but not \"totalizing\") ontological import.
