    在涉及与无行为能力患者的替代决策相关的冲突和不确定性的情况下,通常会咨询临床伦理学家。为了导航这些案例,我们援引一个规范的伦理-法律层次的决策标准:病人已知的愿望,替代判断,和最佳利益。尽管这个层次结构的常规应用,然而,关键的学术文献声称,这些标准未能捕捉到患者的“偏好和代孕行为”。此外,这些批评被纳入顾问实践的程度尚不清楚。在这篇文章中,我将探讨是否,以及如何,对等级制度的现有批评会影响伦理咨询期间这些标准的应用。在讨论了对等级制度的四个批评之后,我研究了两种著名的已发表的伦理咨询方法-生物伦理调解和案例-如何以不同的方式纳入这些批评。然后我认为,虽然两种方法都明确认可相同的层次结构,这四种批评被纳入规定的咨询过程的不同程度可能会产生同一标准的不同应用。我通过案例研究证明,尽管使用了相同的替代判断标准,但遵循两种方法的道德顾问可能会产生两种实质性不同的建议。我得出的结论是,虽然应用程序的这种异构性不应该破坏层次结构作为现场标准的地位,它使建立职业道德咨询共识的项目复杂化。
    AbstractClinical ethicists are routinely consulted in cases that involve conflicts and uncertainties related to surrogate decision-making for incapacitated patients. To navigate these cases, we invoke a canonical ethical-legal hierarchy of decision-making standards: the patient\'s known wishes, substituted judgment, and best interest. Despite the routine application of this hierarchy, however, critical scholarly literature alleges that these standards fail to capture patients\' preferences and surrogates\' behaviors. Moreover, the extent to which these critiques are incorporated into consultant practices is unclear. In this article I thus explore whether, and how, existing critiques of the hierarchy affect the application of these standards during ethics consults. After discussing four critiques of the hierarchy, I examine how two prominent published ethics consultation methodologies-bioethics mediation and CASES-incorporate these critiques differently. I then argue that while both methodologies explicitly endorse the same hierarchy, the varying degrees to which these four criticisms are incorporated into the prescribed consultation process could produce different applications of the same standard. I demonstrate with a case study how an ethics consultant following either methodology might produce two substantively different recommendations despite using the same substituted judgment standard. I conclude that while this heterogeneity of application should not dismantle the hierarchy\'s status as field-wide canon, it complicates projects of professional ethics consultation consensus building.

    智慧是社会判断的标志,但是不同文化的人如何认识智慧仍然不清楚——不同的哲学传统提出了对智慧的基本特征的不同看法。我们在来自12个国家的16个社会经济和文化多样化的便利样本中探索智慧思想的感知。参与者评估了智慧范例,非样本,以及他们自己的19种社会认知特征,随后对目标“智慧”进行评级,知识,和理解。分析揭示了两个正相关的维度——反思取向和社会情绪意识。Thesedimensionsareconsistentacrossthestudedculturalregionsandinteractivewheninformingwissionsratings:wisesttargets—asperceedbyparticipants—scorehighonbothdimensions,而最不明智的人不是反思,而是适度的社会情感。此外,与大多数智慧典范相比,个人认为自己的反思性较低,但具有更多的社会情感意识。我们的发现将民间心理学和社会判断研究扩展到全球北方之外,展示个人如何感知理想的认知和社会情感品质,并有助于理解心灵感知。
    Wisdom is the hallmark of social judgment, but how people across cultures recognize wisdom remains unclear-distinct philosophical traditions suggest different views of wisdom\'s cardinal features. We explore perception of wise minds across 16 socio-economically and culturally diverse convenience samples from 12 countries. Participants assessed wisdom exemplars, non-exemplars, and themselves on 19 socio-cognitive characteristics, subsequently rating targets\' wisdom, knowledge, and understanding. Analyses reveal two positively related dimensions-Reflective Orientation and Socio-Emotional Awareness. These dimensions are consistent across the studied cultural regions and interact when informing wisdom ratings: wisest targets-as perceived by participants-score high on both dimensions, whereas the least wise are not reflective but moderately socio-emotional. Additionally, individuals view themselves as less reflective but more socio-emotionally aware than most wisdom exemplars. Our findings expand folk psychology and social judgment research beyond the Global North, showing how individuals perceive desirable cognitive and socio-emotional qualities, and contribute to an understanding of mind perception.

    UNASSIGNED: Situational Judgement Tests (SJT) are a cost-efficient method for the assessment of personal characteristics (e.g., empathy, professionalism, ethical thinking) in medical school admission. Recently, complex open-ended response format SJTs have become more feasible to conduct. However, research on their applicability to a German context is missing. This pilot study tests the acceptability, reliability, subgroup differences, and validity of an online SJT with open-ended response format developed in Canada (\"Casper\").
    UNASSIGNED: German medical school applicants and students from Hamburg were invited to take Casper in 2020 and 2021. The test consisted of 12 video- and text-based scenarios, each followed by three open-ended questions. Participants subsequently evaluated their test experience in an online survey. Data on sociodemographic characteristics, other admission criteria (Abitur, TMS, HAM-Nat, HAM-SJT) and study success (OSCE) was available in a central research database (stav).
    UNASSIGNED: The full sample consisted of 582 participants. Test-takers\' global perception of Casper was positive. Internal consistency was satisfactory in both years (α=0.73; 0.82) while interrater agreement was moderate (ICC(1,2)=0.54). Participants who were female (d=0.37) or did not have a migration background (d=0.40) received higher scores. Casper scores correlated with HAM-SJT (r=.18) but not with OSCE communication stations performance. The test was also related to Abitur grades (r=-.15), the TMS (r=.18), and HAM-Nat logical reasoning scores (r=.23).
    UNASSIGNED: This study provides positive evidence for the acceptability, internal consistency, and convergent validity of Casper. The selection and training of raters as well as the scenario content require further observation and adjustments to a German context to improve interrater reliability and predictive validity.
    UNASSIGNED: Situational Judgement Tests (SJTs) sind eine kosteneffiziente Methode zur Beurteilung von persönlichen Eigenschaften (z.B. Empathie, Professionalität, ethisches Denken) bei der Zulassung zum Medizinstudium. Die Durchführung komplexer SJTs mit offenem Antwortformat ist in jüngster Zeit einfacher geworden. Es fehlen jedoch Untersuchungen zu ihrer Anwendbarkeit im deutschen Kontext. Diese Pilotstudie testet die Akzeptanz, Reliabilität, Subgruppenunterschiede und Validität eines in Kanada entwickelten Online-SJTs mit offenem Antwortformat („Casper“).
    UNASSIGNED: Studienbewerber*innen aus Deutschland und Medizinstudierende aus Hamburg wurden eingeladen, Casper in den Jahren 2020 und 2021 zu absolvieren. Der Test bestand aus 12 video- und textbasierten Szenarien, auf die jeweils drei offene Fragen folgten. Die Teilnehmenden bewerteten anschließend ihre Testerfahrung in einer Online-Umfrage. Daten zu soziodemografischen Merkmalen, weiteren Zulassungskriterien (Abitur, TMS, HAM-Nat, HAM-SJT) und zum Studienerfolg (OSCE) waren in einer zentralen Forschungsdatenbank (stav) verfügbar.
    UNASSIGNED: Die Gesamtstichprobe bestand aus 582 Teilnehmenden. Die allgemeine Wahrnehmung von Casper durch die Testteilnehmenden war positiv. Die interne Konsistenz war in beiden Jahren zufriedenstellend (α=0,73; 0,82), während die Interrater-Übereinstimmung mäßig war (ICC(1,2)=0,54). Weibliche Teilnehmerinnen (d=0,37) oder Teilnehmende ohne Migrationshintergrund (d=0,40) erzielten höhere Testwerte. Die Casper Testwerte korrelierten mit dem HAM-SJT (r=.18), aber nicht mit der Leistung in OSCE-Kommunikationsstationen. Der Test zeigte auch Zusammenhänge mit der Abiturnote (r=-.15), dem TMS (r=.18) und dem HAM-Nat-Subtest für logisches Denken (r=.23).
    UNASSIGNED: Die Studie liefert positive Belege für die Akzeptanz, interne Konsistenz und konvergente Validität von Casper. Die Auswahl und Schulung der Beurteiler*innen sowie die Inhalte der Szenarien bedürfen weiterer Untersuchungen und Anpassungen an den deutschen Kontext, um die Interrater-Reliabilität und prädiktive Validität zu verbessern.

    众包通过将问题分配给大量称为人群的非专家来解决问题。在这些系统中,问题的最终答案是通过总结从社区获得的选票来确定的。通过促进社区成员通过移动电话和因特网的访问,这些系统的普及已经增加。众包提出的问题之一是如何选择人以及如何收集答案。通常,用户根据他们在预测试中的表现进行分离。设计性能计算的预测试具有挑战性;应选择预测试问题来评估与主要问题相关的个人特征。提高众包系统准确性的方法之一是通过考虑个人的认知特征和决策模型来形成人群,并提高他们对问题答案准确性的估计。人们可以在做出决定时估计他们的回答的正确性。这种估计的准确性由称为元认知能力的量决定。元运算指的是将置信水平与答案一起考虑以提高解决方案的准确性的情况。在本文中,通过数学和实验分析,我们将回答以下问题:是否有可能通过理解个人“元认知”并记录和利用用户对其答案的信心来提高众包系统的性能?
    Crowdsourcing deals with solving problems by assigning them to a large number of non-experts called crowd using their spare time. In these systems, the final answer to the question is determined by summing up the votes obtained from the community. The popularity of these systems has increased by facilitating access for community members through mobile phones and the Internet. One of the issues raised in crowdsourcing is how to choose people and how to collect answers. Usually, users are separated based on their performance in a pre-test. Designing the pre-test for performance calculation is challenging; The pre-test questions should be selected to assess characteristics in individuals that are relevant to the main questions. One of the ways to increase the accuracy of crowdsourcing systems is by considering individuals\' cognitive characteristics and decision-making models to form a crowd and improve the estimation of their answer accuracy to questions. People can estimate the correctness of their responses while making a decision. The accuracy of this estimate is determined by a quantity called metacognition ability. Metacoginition is referred to the case where the confidence level is considered along with the answer to increase the accuracy of the solution. In this paper, by both mathematical and experimental analysis, we would answer the following question: Is it possible to improve the performance of a crowdsourcing system by understanding individuals\' metacognition and recording and utilizing users\' confidence in their answers?

    四个实验检查了人类对因果有效性的评价,以及检测因果关系的能力,在非语言范式中。参与者以并发随机间隔做出回应,灭绝时间表。在有一个刺激的情况下,反应产生了结果(三角闪光);在其他刺激存在的情况下,他们没有。在做出因果有效性判断后,两个进一步的刺激同时出现,参与者必须根据前两种刺激中的哪一种与有效反应相关来选择一种刺激。在所有的实验中,与延迟3s的结果相比,直接结果与更高的因果评级和更好的因果检测相关。在反应和结果之间插入的信号改善了评级和检测(实验2和4),即使它是连续的反应,但不是结果(实验2和3)。与两种成分(标记提示)相关的刺激不会影响判断或检测(实验3)。如果做出反应(信号强化),则刺激信号传递结果的可用性并不能改善因果判断,但确实改善了与结果相关的刺激的检测(实验4)。延迟期间的响应在延迟未发信号时干扰实际关系的检测(实验1-4),但没有完全或短暂的信号延迟(实验2-4),或带有信号强化(实验4)。结果表明,延迟刺激用于表明响应已成功,并通过提供判别功能来区分延迟周期。这些发现反映了在非人类条件下看到的那些。(PsycInfo数据库记录(c)2024APA,保留所有权利)。
    Four experiments examined human ratings of causal effectiveness, and ability to detect causal relationships, in a nonverbal paradigm. Participants responded on a concurrent random interval, extinction schedule. In the presence of one stimulus, responses produced an outcome (triangle flash); in the presence of the other stimulus, they did not. Following making a judgment of causal effectiveness, two further stimuli were presented simultaneously with one another, and participants had to select one depending on which of the previous two stimuli were associated with effective responses. In all experiments, immediate outcomes were associated with higher causal ratings and better causal detection than outcomes delayed by 3 s. A signal inserted between response and outcome improved ratings and detection (Experiments 2 and 4), even when it was contiguous with the response but not the outcome (Experiments 2 and 3). Stimuli associated with both components (marking cues) did not impact judgments or detection (Experiment 3). Stimuli signaling the availability of an outcome if a response was made (signaled reinforcement) did not improve causal judgments, but did improve detection of stimuli associated with the outcome (Experiment 4). Responses during the delay interfered with detection of the actual relationship when delays were unsignaled (Experiments 1-4), but not with fully or briefly signaled delays (Experiments 2-4), or with signaled reinforcement (Experiment 4). The results suggest a delay stimulus serves to signal the response has been successful and demark the delay period by serving a discriminative function. These findings mirror those seen in nonhuman conditioning. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

    反事实理论认为,人们的因果判断能力取决于他们考虑其他可能性的能力:雷击导致森林火灾,因为它没有击中,森林大火不会随之而来。为了适应因果判断的各种心理影响,最近的一系列报道提出,人们从概率上抽样反事实替代方案,从中计算因果强度的分级度量。虽然这样的模型成功地描述了统计正态的影响(即,基本比率)对因果判断的候选和替代原因,我们表明,他们对正常性如何影响人们对其因果判断的信心做出了进一步未经测试的预测。在因果判断任务的大量(N=3,020)参与者样本中,我们发现,正态确实会影响人们对因果判断的信心,并且这些影响是通过反事实抽样模型预测的,在该模型中,当原因的影响在想象的反事实可能性中变化较小时,人们对因果关系更有信心。(PsycInfo数据库记录(c)2024APA,保留所有权利)。
    Counterfactual theories propose that people\'s capacity for causal judgment depends on their ability to consider alternative possibilities: The lightning strike caused the forest fire because had it not struck, the forest fire would not have ensued. To accommodate a variety of psychological effects on causal judgment, a range of recent accounts have proposed that people probabilistically sample counterfactual alternatives from which they compute a graded measure of causal strength. While such models successfully describe the influence of the statistical normality (i.e., the base rate) of the candidate and alternate causes on causal judgments, we show that they make further untested predictions about how normality influences people\'s confidence in their causal judgments. In a large (N = 3,020) sample of participants in a causal judgment task, we found that normality indeed influences people\'s confidence in their causal judgments and that these influences were predicted by a counterfactual sampling model in which people are more confident in a causal relationship when the effect of the cause is less variable among imagined counterfactual possibilities.

    过去关于采纳建议的研究表明,在结合顾问的预测时,人们通常对建议的独立性水平不敏感。然而,这主要是在人们收到数字预测的情况下进行的测试。Mislavsky和Gaertig(2022)最近的工作表明,人们有时会采用不同的策略来结合口头和数字预测未来事件的可能性。具体来说,基于两个口头预测的可能性判断(例如,\“相当可能\”)通常是极端的(相对于预测),而不是基于两个数字预测的可能性判断(例如,“70%的概率”)。本研究的目的是调查当独立性差异非常显著时,建议接受者使用组合策略是否对建议独立性敏感,以及对建议独立性的敏感性是否取决于给出建议的格式。在两项研究中,我们发现,当结合使用单独证据的顾问的预测时,建议接受者对自己的可能性估计变得更加极端,与同样的证据相反。我们还发现,与两个数字预测相比,两个口头预测通常会产生更极端的组合可能性估计。然而,结果并不表明对建议独立性的敏感性取决于建议的格式.(PsycInfo数据库记录(c)2024APA,保留所有权利)。
    Past research on advice-taking has suggested that people are often insensitive to the level of advice independence when combining forecasts from advisors. However, this has primarily been tested for cases in which people receive numeric forecasts. Recent work by Mislavsky and Gaertig (2022) shows that people sometimes employ different strategies when combining verbal versus numeric forecasts about the likelihood of future events. Specifically, likelihood judgments based on two verbal forecasts (e.g., \"rather likely\") are more often extreme (relative to the forecasts) than are likelihood judgments based on two numeric forecasts (e.g., \"70% probability\"). The goal of the present research was to investigate whether advice-takers\' use of combination strategies can be sensitive to advice independence when differences in independence are highly salient and whether sensitivity to advice independence depends on the format in which advice is given. In two studies, we found that advice-takers became more extreme with their own likelihood estimate when combining forecasts from advisors who use separate evidence, as opposed to the same evidence. We also found that two verbal forecasts generally resulted in more extreme combined likelihood estimates than two numeric forecasts. However, the results did not suggest that sensitivity to advice independence depends on the format of advice. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

    政治错误信息对全世界的民主国家构成了重大威胁,经常煽动对立政治团体之间的激烈争端。尽管它在知情选民和政治决策中发挥了核心作用,人们很少知道人们在区分准确的政治信息和虚假信息时是对还是错。这里,我们调查人们对自己发现政治错误信息的能力的元认知洞察力。我们使用来自6个月内12波的独特纵向研究的数据,该研究调查了一个代表性的美国样本(N=1,191),了解在线上最广泛传播的政治(错误)信息。利用信号检测理论方法对元认知进行建模,我们发现,政治左翼和政治右翼的人们都知道他们在所有新闻中如何区分准确的政治信息和虚假信息。然而,当有关信息挑战他们的意识形态承诺时,共和党人和保守派的这种元认知洞察力要比民主党人和自由派的要低得多。也就是说,鉴于他们的知识水平,共和党人和保守派的信心不太可能反映他们对与他们的政治观点不符的真实和虚假政治陈述的真实判断的正确性。这些结果揭示了复杂而系统的方式,其中政治偏好与人们评估自己的真相识别的准确性相关联。更广泛地说,通过确定特定的政治不对称-相对于和谐新闻的不和谐-我们的发现强调了元认知在延续和加剧意识形态分歧中的作用。(PsycInfo数据库记录(c)2024APA,保留所有权利)。
    Political misinformation poses a major threat to democracies worldwide, often inciting intense disputes between opposing political groups. Despite its central role for informed electorates and political decision making, little is known about how aware people are of whether they are right or wrong when distinguishing accurate political information from falsehood. Here, we investigate people\'s metacognitive insight into their own ability to detect political misinformation. We use data from a unique longitudinal study spanning 12 waves over 6 months that surveyed a representative U.S. sample (N = 1,191) on the most widely circulating political (mis)information online. Harnessing signal detection theory methods to model metacognition, we found that people from both the political left and the political right were aware of how well they distinguished accurate political information from falsehood across all news. However, this metacognitive insight was considerably lower for Republicans and conservatives-than for Democrats and liberals-when the information in question challenged their ideological commitments. That is, given their level of knowledge, Republicans\' and conservatives\' confidence was less likely to reflect the correctness of their truth judgments for true and false political statements that were at odds with their political views. These results reveal the intricate and systematic ways in which political preferences are linked to the accuracy with which people assess their own truth discernment. More broadly, by identifying a specific political asymmetry-for discordant relative to concordant news-our findings highlight the role of metacognition in perpetuating and exacerbating ideological divides.

    背景:先前的研究表明,正念与日常生活中较慢的时间流逝有关,自我报告的时间压力较低。这项研究调查了这些关系背后的一些潜在机制。
    方法:318名参与者提交了他们对在线调查的答复,该调查收集了有关时间流逝判断的数据,时间压力,特质正念,气质,任务加载,和关于时间的元认知。使用共性和优势分析,我们探索了这些变量是如何发挥作用的,无论是单独还是联合,预测参与者的时间似乎过得有多快(或多慢),或者他们觉得时间有多紧迫。
    结果:正念和气质在月和2个月尺度上预测时间判断和时间压力的能力上有一些重叠。外向/摄政的气质特征,以及正念的非判断和非反应方面是时间判断和时间压力的最佳预测因素。注意力相关变量主要通过参与与其他变量的联合效应而与时间感知相关。结果还表明,关于时间的元认知在预测时间判断的流逝时与其他变量相互作用,但只在月尺度上。最后,在本研究的所有变量中,任务负荷在周和月尺度上对自我报告时间压力的预测参与程度最高,但它对预测时间流逝的判断贡献相对较小。
    结论:结果表明,正念通过参与推理过程与时间的流逝有关。数据还显示了不同因素在不同时间尺度上与PoTJ的关系。最后,结果表明,在时间流逝和时间压力与其他纳入变量的关系方面存在异同。
    BACKGROUND: Previous research has shown that mindfulness is associated with slower passage of time in everyday life, and with lower self-reported time pressure. This study investigates some of the potential mechanisms behind these relationships.
    METHODS: 318 participants submitted their responses to an online survey which collected data regarding passage of time judgments, time pressure, trait mindfulness, temperament, task load, and metacognitions about time. Using commonality and dominance analyses, we explored how these variables contributed, either alone or jointly, to predicting how fast (or slow) time seems to pass for participants, or how pressed for time they felt.
    RESULTS: Mindfulness and temperament had some overlaps in their ability to predict passage of time judgments and time pressure for durations at the month and 2-month scales. The temperamental trait of extraversion/surgency, as well as the Non-judging and Non-reacting facets of mindfulness were among the best predictors of passage of time judgments and time pressure. Attention-related variables were mainly related to time perception via their involvement in joint effects with other variables. Results also suggested that metacognitions about time interacted with other variables in predicting passage of time judgments, but only at the month scale. Finally, among all the variables included in this study, task load had the highest degree of involvement in predictions of self-reported time pressure at the week and month scales, but it contributed relatively little to predicting passage of time judgments.
    CONCLUSIONS: Results suggest that mindfulness relates to passage of time through its involvement in inferential processes. The data also shows how different factors are related to PoTJ at different time scales. Finally, results suggest the existence of both similarities and differences in how passage of time and time pressure relate to the other included variables.

    儿童行人受伤是一项重大的公共卫生挑战。了解过马路所需的最复杂的认知技能有助于我们理解,改进,保护交通中的儿童,不发达的认知技能可能会影响儿童的行人安全。过马路的一个复杂组成部分是判断迎面而来的交通到达时间的认知感知任务。我们检查了7岁和8岁儿童判断从不同距离和速度驶来的车辆的到达时间的能力,以及在虚拟现实(VR)行人模拟器中进行密集的过马路训练后这些判断的改善。
    500名7岁和8岁儿童参加了一项随机试验,评估使用大型信息亭VR与基于智能手机的VR耳机来教授过马路技能。在随机进入VR训练条件之前,也在开始任何训练之前,儿童从事基于视频的车辆方法估计任务,以评估判断交通到达时间的能力。然后,他们在随机分配的条件下进行了多次基于VR的行人安全培训课程,直到实现成人功能。训练后不久,6个月后,孩子们重复了车辆估计任务。
    在随机化或训练之前,孩子们更准确地判断到达时间,距离更近和更远的交通,快速移动与慢速移动的交通,但是这些结果被速度x距离相互作用所包含。交互建议的距离提示比速度提示使用得更突出,速度在不同的距离有不同的影响。训练组对学习的影响很小,所有儿童在训练后判断车辆到达时间方面都变得更好。
    儿童倾向于低估车辆到达时间。距离提示比速度提示对到达时间判断的影响更大,但是基于车辆速度操纵和车辆距离操纵的儿童估计改进了训练后。改进在六个月后保留。这一发现与心理物理学研究一致,该研究表明车辆接近判断依赖于光学尺寸和迫在眉睫,受到车速和距离的影响。建议实施基于VR的儿童行人安全培训,因为它可以提高儿童对车辆到达时间的判断,但必须谨慎进行,以避免医源性影响。
    UNASSIGNED: Child pedestrian injuries represent a significant public health challenge. Understanding the most complex cognitive skills required to cross streets helps us understand, improve, and protect children in traffic, as underdeveloped cognitive skill likely impacts children\'s pedestrian safety. One complex component of street-crossing is the cognitive-perceptual task of judging time-to-arrival of oncoming traffic. We examined capacity of 7- and 8-year-olds to judge time-to-arrival for vehicles approaching from varying distances and speeds, as well as improvement in those judgments following intensive street-crossing training in a virtual reality (VR) pedestrian simulator.
    UNASSIGNED: 500 seven- and eight-year-olds participated in a randomized trial evaluating use of a large kiosk VR versus smartphone-based VR headset to teach street-crossing skills. Prior to randomization into VR training condition and also prior to initiation of any training, children engaged in a video-based vehicle approach estimation task to assess ability to judge traffic time-to-arrival. They then engaged in multiple VR-based pedestrian safety training sessions in their randomly assigned condition until achieving adult functioning. Soon after training and again 6 months later, children repeated the vehicle estimation task.
    UNASSIGNED: Prior to randomization or training, children were more accurate judging time to arrival for closer versus farther traffic, and rapidly-moving versus slower-moving traffic, but those results were subsumed by a speed x distance interaction. The interaction suggested distance cues were used more prominently than speed cues, and speed had varying effects at different distances. Training group had minimal effect on learning and all children became significantly better at judging vehicle arrival times following training.
    UNASSIGNED: Children tend to underestimate vehicle arrival times. Distance cues are more impactful on time-to-arrival judgments than speed cues, but children\'s estimations based both on manipulations of vehicle speed and manipulations of vehicle distance improved post-training. Improvements were retained six months later. This finding is consistent with psychophysics research suggesting vehicle approach judgments rely on optical size and looming, which are impacted both by vehicle speeds and distances. Implementation of VR-based training for child pedestrian safety is recommended, as it may improve children\'s judgment of vehicle time-to-arrival, but it must be conducted cautiously to avoid iatrogenic effects.
