Third-party punishment (TTP) promotes social cooperation and enforces social norms. Even children are willing to pay a cost to implement such punishment. While children punish for retributive and consequentialist concern focused on the violator, whether they consider victims’ feelings when implement TPP remains unclear. This research investigated whether six-, eight-, and ten-year-old Chinese children (N = 218) take victims’ responses into consideration when punishing moral, conventional, and personal violations. Participants were shown violations across domains with response (positive vs. negative) or without response and were asked to decide whether to pay a cost to punish the violator. According to Experiment 1, children of each age made distinctions between social domains in their TPP. Victims’ positive responses decreased TPP in the moral domain, but not in the conventional or personal domains. Experiment 2 revealed that nine-year-olds (not six-year-olds) punished less when the victim (compared to a bystander) gave a positive response. This study identified the development of children’s costly TPP across domains and the influence of victims’ responses on children’s punishment.
第三方惩罚(TTP)促进社会合作,执行社会规范。即使是孩子也愿意为实施这种惩罚付出代价。虽然儿童惩罚的报复性和结果主义关注的重点是违法者,但他们在实施TPP时是否考虑受害者的感受尚不清楚。本研究调查了6岁、8岁和10岁的中国儿童(N = 218)在惩罚道德、传统和个人违规行为时是否会考虑受害者的反应。参与者被展示了不同领域的违规行为,有回应(积极的和消极的)或没有回应,并被要求决定是否支付惩罚违规者的费用。根据实验1,不同年龄的儿童在TPP中对社会领域进行了区分。受害者的积极反应在道德领域降低了TPP,但在传统或个人领域没有。实验2显示,当受害者(与旁观者相比)做出积极回应时,9岁的孩子(而不是6岁的孩子)受到的惩罚更少。本研究确定了儿童昂贵的跨领域TPP的发展以及受害者的反应对儿童惩罚的影响。

The ability to abstract the numerosity of a set, independent of perceptual attributes such as color, shape, or texture, is critical to a true understanding of number. Substantial evidence suggests that variations in perceptual attributes of sets (e.g., differing colors and shapes of items) hinder preschoolers’ abilities to exactly match the number of items across sets. Yet, it is unclear whether it is the precise nature of the demands of a matching task that may highlight perceptual attributes of items within the set. Less work has focused on how perceptual variations influence approximate (i.e., imprecise) numerical abilities, such as numerical discrimination. In the present study, 3–10-year-old children and adults were asked to compare sets of items with different perceptual attributes either within the set (e.g., sets containing both blue and red items), across the set pairs (e.g., comparing a set of red items to a set of blue items), or both. Results reveal discriminations through early childhood and adulthood were impaired when perceptual characteristics differed across the sets but not when these variations occurred within the sets themselves. These findings suggest that perceptual variability impacts approximate numerosity judgments, hinting at the processes involved in numerical discrimination.
抽象一组数字的能力,独立于颜色、形状或纹理等感知属性,对真正理解数字至关重要。大量证据表明,集合感知属性的变化(例如,不同颜色和形状的物品)阻碍了学龄前儿童准确匹配集合中物品数量的能力。然而,尚不清楚是否是匹配任务的需求的精确性质可能突出了集合中项目的感知属性。较少的工作集中在感知变化如何影响近似(即,不精确的)数字能力,如数字辨别。在目前的研究中,3 - 10岁的儿童和成人被要求比较具有不同知觉属性的物品,或者在集合内(例如,包含蓝色和红色物品的集合),跨集合对(例如,比较一组红色物品和一组蓝色物品),或者两者都比较。结果显示,当知觉特征在组间不同时,幼儿期和成年期的辨别能力受损,而当这些变化发生在组内时则不会受损。这些发现表明,知觉变化影响近似数字判断,暗示了涉及数字歧视的过程。

The decision threshold describes the minimum probability a person needs to be certain enough to make a decision. Lower decision thresholds lead people to jump to conclusions and are associated with superstitious and conspiracy-related beliefs. To shed light on the role of the decision threshold in the development of these phenomena, it is crucial to study decision thresholds at an early age. However, current measures of decision thresholds have only been administered in adult samples and are based on subjective probability estimates. The current study validates a new instrument that was adapted to measure the decision thresholds of children and is based on the objective probability values of a situation by using a signal detection analytical approach. We assessed decision thresholds in a sample of N = 299 children from an extracurricular enrichment program for talented primary school students. Receiver operating characteristic curves indicated that the new measurement instrument has high sensitivity. Furthermore, its construct validity was supported by positive associations with children’s performance in the original beads task, a measure of confirmation bias, age, grade level, and math performance. However, no associations were found with a measure of alternation bias, epistemic certainty beliefs, self-concept in data-related tasks, general self-efficacy, or gender. This study introduces a new instrument for measuring the decision threshold in children using objective probability values and gives insights into decision-making processes and their implications for cognitive biases and related constructs.
决策阈值描述了一个人需要足够确定才能做出决定的最小概率。较低的决策阈值导致人们过早下结论,并与迷信和阴谋论相关的信仰有关。为了阐明决策阈值在这些现象发展中的作用,研究早期的决策阈值是至关重要的。然而,目前的决策阈值措施仅在成人样本中实施,并且基于主观概率估计。目前的研究验证了一种新的工具,该工具适用于测量儿童的决策阈值,并基于使用信号检测分析方法的情况的客观概率值。我们评估了N = 299名学生的决策阈值,这些孩子来自一个为有天赋的小学生提供的课外丰富项目。接收机工作特性曲线表明,新型测量仪器具有较高的灵敏度。此外,其结构效度与儿童在原始珠子任务中的表现、确认偏差、年龄、年级水平和数学表现呈正相关。然而,与交替偏差、认知确定性信念、数据相关任务中的自我概念、一般自我效能或性别的测量没有发现关联。本研究介绍了一种利用客观概率值测量儿童决策阈值的新工具,并对决策过程及其对认知偏差和相关结构的影响进行了深入研究。

Fractions knowledge is widely recognized as a key building block for developing mathematical competence. However, many children face difficulties learning fractions. Recognizing these challenges, researchers have sought potential leverage points to enhance children’s fraction learning. In the present study, we investigated the relative contributions of verbal skills vs. non-verbal, non-symbolic number processing to 5th- to 7th- grade children’s fractions skills. Specifically, we compared two math-specific verbal skills—transcoding and mathematics vocabulary—and two skills representing non-symbolic analog magnitudes—approximate number sense acuity and acuity for processing non-symbolic ratios. To assess children’s symbolic fraction abilities, we used an experimental fraction arithmetic error detection task alongside a fraction magnitude comparison task, with fractions stimuli composed of two-digit components. Critically, mathematics vocabulary was the only predictor of interest that significantly predicted performance on both the error detection and comparison tasks. Our findings underscore the importance of math-specific verbal skills in supporting children’s fraction abilities, perhaps implicating their role in fostering conceptual understanding, while indicating a limited role for analog representational skills.
分数知识被广泛认为是发展数学能力的关键组成部分。然而,许多孩子在学习分数方面存在困难。认识到这些挑战,研究人员已经寻找潜在的杠杆点,以提高儿童的分数学习。在本研究中,我们调查了语言技能与非语言、非符号数字处理对5 - 7年级儿童分数技能的相对贡献。具体来说,我们比较了两种特定于数学的语言技能——编码转换和数学词汇——以及两种代表非符号模拟量级的技能——近似数感敏锐度和处理非符号比率的敏锐度。为了评估儿童的符号分数能力,我们使用了一个实验分数算术错误检测任务和一个分数大小比较任务,分数刺激由两位数组成。重要的是,数学词汇是唯一能显著预测错误检测和比较任务表现的预测因素。我们的研究结果强调了数学语言技能在支持儿童分数能力方面的重要性,这可能暗示了它们在培养概念理解方面的作用,同时表明模拟表征技能的作用有限。

Understanding reading development requires investigating how visual word recognition capacities develop, particularly through lexical decision tasks. Traditionally, accuracy and reaction times (RTs) are analysed separately, overlooking their interaction, which provides crucial insights into performance. This study proposes a novel framework, hypothesizing that error dynamics (i.e., error distribution through RTs) could be an objective marker of reading efficiency. To test this hypothesis, the study investigated the relationship between reading skills in learning-to-read children and the dynamics of lexical decision errors. Lexical decision performance was analysed in 56 French-speaking children (22 Grade 1 and 34 Grade 2, 36 females). Two complementary methodologies were employed: RTs comparison between correct and incorrect responses and Conditional Accuracy Functions (CAFs) to evaluate accuracy as a function of RTs. Results showed that pseudoword errors were faster than correct responses whereas word errors were slower than correct responses. Of importance, fewer slow word errors and more fast pseudoword errors correlated with reading skills. The findings suggested that as reading skills improve, error dynamics would progressively shift from slow word errors to fast pseudoword errors. This study demonstrated that integrating accuracy and RTs via error dynamics analysis could provide objective markers of reading development. Crucially, it highlights a novel developmental index of reading skills through the shift of error patterns, offering a promising avenue for early identification of reading difficulties.
理解阅读发展需要研究视觉单词识别能力是如何发展的,特别是通过词汇决策任务。传统上,准确性和反应时间(RTs)是分开分析的,忽略了它们之间的相互作用,而这种相互作用提供了对性能的重要见解。本研究提出了一个新的框架,假设错误动态(即通过RTs的错误分布)可能是阅读效率的客观标志。为了验证这一假设,本研究调查了学习阅读儿童的阅读技能与词汇决策错误的动态之间的关系。对56名法语儿童(22名一年级学生和34名二年级学生,其中36名女生)的词汇决策表现进行了分析。采用了两种互补的方法:正确和错误反应之间的RTs比较和条件准确性函数(CAFs)来评估作为RTs函数的准确性。结果表明,假词错误比正确反应快,而单词错误比正确反应慢。重要的是,更少的慢词错误和更多的快速假词错误与阅读技能有关。研究结果表明,随着阅读技能的提高,错误动态将逐渐从缓慢的单词错误转变为快速的假词错误。本研究表明,通过误差动力学分析将准确性和RTs结合起来,可以为阅读发展提供客观的指标。至关重要的是,它强调了一种通过错误模式转变的阅读技能的新发展指数,为早期识别阅读困难提供了有希望的途径。

The core assumptions of the integrated theory of numerical development were tested using a cross-sectional sample of 379 fifth-grade students, who were assessed on their understanding of whole numbers and fractions, including arithmetic skills. An additional factor of part-whole knowledge was also assessed and analyzed in four structural equation models. All models showed non-significant chi-square values and good fit indices according to common modelling benchmarks. As hypothesized, whole number magnitude knowledge predicts fraction magnitude knowledge and arithmetic proficiency. Additionally, part-whole knowledge mediates numerical magnitude understanding but does not predict arithmetic outcomes. These findings are in line with the integrated theory of numerical development, suggesting that numerical magnitude knowledge is crucial for both numerical development and arithmetic learning. Our findings also reveal that part-whole knowledge may serve as a bridge to more advanced magnitude understanding. Theoretical and practical implications are discussed.
通过对379名五年级学生的横断面抽样,对数值发展综合理论的核心假设进行了测试,评估了他们对整数和分数的理解,包括算术技能。在四种结构方程模型中,还对部分-整体知识的附加因素进行了评估和分析。根据常用的建模基准,所有模型均显示非显著的卡方值和良好的拟合指数。正如假设的那样,整数量级的知识预测分数量级的知识和算术能力。此外,部分-整体知识介导数值量级的理解,但不预测算术结果。这些发现与数值发展的综合理论一致,表明数值量级知识对数值发展和算术学习都至关重要。我们的研究结果还表明,部分-整体知识可以作为通往更高级量级理解的桥梁。讨论了理论和实践意义。

Shared book reading is an important context for children’s vocabulary development. Yet, the process by which word learning is influenced by the characteristics of both the learning material and the learner remains poorly understood – particularly in relation to contemporary digital literacy practice. We examined the effects of book format (print vs. digital) and individual differences in prior vocabulary knowledge and executive functions on children’s word learning. English-speaking caregivers and their 4- to 5-year-olds took part in this study (N = 99; child’s Mage = 57.5 months; 57.6 % girls). In a cross-sectional, within-subjects design, dyads read one of two custom storybooks in print, and the other in digital format, with order of book and format presentation counterbalanced across participants. Word learning was assessed with tests of production, definition, and comprehension. There was no evidence of a main effect of book format across word learning measures, however, several child characteristics influenced word learning. Prior vocabulary knowledge predicted performance on all word learning measures, boys were more accurate than girls in tests of definition and comprehension, and executive functions significantly predicted performance in the definition test. In addition, there was a significant cross-over interaction between book format and executive functions for the comprehension test scores. In the digital book condition only, higher comprehension test scores were obtained by children who scored more highly on the measures of executive functions. Overall, these findings underscore the importance of considering individual differences and multiple outcomes when studying learning from different media.
共同阅读是儿童词汇发展的重要语境。然而,单词学习受到学习材料和学习者特征影响的过程仍然知之甚少,特别是在当代数字扫盲实践中。本研究考察了图书格式(印刷版与电子版)和个体差异对儿童词汇学习的影响,以及先前词汇知识和执行功能的影响。说英语的照顾者和他们4到5岁的孩子参加了这项研究(N = 99;儿童法师= 57.5个月;57.6%女孩)。在横断面的主题内设计中,二人组阅读两本定制的印刷故事书中的一本,另一本是数字格式的,书的顺序和格式呈现在参与者之间是平衡的。单词学习通过生成、定义和理解测试进行评估。没有证据表明书籍格式对单词学习有主要影响,然而,几个儿童特征影响单词学习。先前的词汇知识预测了所有单词学习测试的成绩,男孩在定义和理解测试中比女孩更准确,执行功能显著预测了定义测试的成绩。此外,书本格式与执行功能对理解测试成绩有显著的交叉交互作用。仅在电子书条件下,执行功能测试得分较高的儿童获得了更高的理解测试分数。总的来说,这些发现强调了在研究从不同媒体学习时考虑个体差异和多种结果的重要性。

In the digital book condition only, higher comprehension test scores were obtained by children who scored more highly on the measures of executive functions. Overall, these findings underscore the importance of considering individual differences and multiple outcomes when studying learning from different media.</div></div>","PeriodicalId":48391,"journal":{"name":"Journal of Experimental Child Psychology","volume":"260 ","pages":"Article 106345"},"PeriodicalIF":1.8,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144654220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Children often attend to social group differences when making decisions. Here, we investigated group preferences among Hong Kong children: 115 Chinese children (Mage = 67.56 months, SD = 10.35 months; 52 girls, 63 boys) and 84 ethnic minority South Asian/Southeast Asian (or SA/SEA; Mage = 76.50 months, SD = 11.59 months; 42 girls, 42 boys). Participants were presented with an ethnic ingroup individual and an ethnic outgroup individual on a computer screen, indicating their preference for one individual over the other in the study. They were randomly assigned to one of two conditions, one in which their ethnic group member was portrayed as wealthy while the other individual was portrayed as poor, one in which their group member was poor while the other individual was wealthy. Chinese children preferred to socialize with the ethnic ingroup child over the ethnic outgroup child. By contrast, SA/SEA children preferred to socialize with ethnic outgroup individuals. For both groups of children, the wealth of the presented individuals impacted their preferences. These findings, drawn from Hong Kong where an ethnic majority group co-resides with several visible ethnic minority groups, provide insights about how group status as it intersects with ethnicity functions as a key mechanism in determining group preferences.
孩子们在做决定时经常注意到社会群体的差异。在这里,我们调查了香港儿童的群体偏好:115名中国儿童(Mage = 67.56个月,SD = 10.35个月;52名女孩,63名男孩)和84名南亚/东南亚少数民族(或SA/SEA;Mage = 76.50个月,SD = 11.59个月;42个女孩,42个男孩)。研究人员在电脑屏幕上向参与者展示了一个族群内的个体和一个族群外的个体,表明他们在研究中对其中一个个体的偏好。他们被随机分配到两种情况中的一种,在一种情况下,他们的种族成员被描绘成富人,而另一个人被描绘成穷人,在一种情况下,他们的种族成员是穷人,而另一个人是富人。中国儿童更倾向于与族群内儿童交往,而非族群外儿童。相比之下,东南亚裔儿童更喜欢与少数民族外群体的个体交往。对于两组孩子来说,在场个人的财富影响了他们的偏好。这些发现来自香港,在那里一个多数民族与几个少数民族共同居住,提供了关于群体地位如何与种族相交的见解,作为决定群体偏好的关键机制。

The role of valence in children’s and adults’ cross-modal integration of emotional prosody and emotional faces 效价在儿童和成人情绪韵律和情绪面孔跨模态整合中的作用

Previous research indicates that preschoolers match emotional prosody with a corresponding emotional face when choosing between a positively versus negatively-valenced face. However, it is unclear whether these decisions are guided by discrete emotion categories or by coarse-grained valence distinctions. Here, we examined adults’ and children’s cross-modal matching of emotional prosody with one of two faces whose depicted emotions either contrasted in valence (e.g., happy vs. sad) or fell within the same valence category (e.g., sad vs. angry). First, to provide a basis for comparison for children’s performance, adults were presented with auditory stimuli and asked to choose a matching emotional face when the non-matching alternative either contrasted in valence (Exp. 1) or had the same valence (Exp. 2). Adults correctly matched emotional prosody with corresponding faces in both cases. In contrast, although 5-year-olds correctly matched emotional prosody when the alternative faces contrasted in valence (Exp. 3), they succeeded with within-valence distinctions only when differentiating negatively-valenced discrete emotions and not positively-valenced ones (Exp. 4). By 8 years of age, children accurately differentiated same-valence discrete emotions regardless of whether they were negatively- or positively-valenced (Exp. 5). Implications for the developmental trajectory of children’s recognition of discrete emotional prosody categories are discussed.
先前的研究表明,学龄前儿童在选择积极和消极价值的面孔时,会将情绪韵律与相应的情绪面孔相匹配。然而,尚不清楚这些决定是由离散的情感类别还是由粗粒度的价态差异指导的。在这里,我们研究了成人和儿童的情绪韵律与两张面孔中的一张的跨模态匹配,这两张面孔所描绘的情绪要么在效价上相反(例如,快乐与悲伤),要么属于同一效价类别(例如,悲伤与愤怒)。首先,为了给儿童的表现提供一个比较的基础,我们向成人提供听觉刺激,并要求他们在不匹配的备选方案的效价不同(实验1)或效价相同(实验2)时选择一个匹配的情绪面孔。在这两种情况下,成年人都能正确地将情绪韵律与相应的面孔匹配起来。相比之下,尽管5岁儿童在不同的面孔在效价上进行对比时能够正确匹配情绪韵律(实验3),但他们只有在区分负效价的离散情绪时才能成功匹配效价内的差异,而不能区分正效价的离散情绪(实验4)。到8岁时,儿童能够准确地区分同效价离散情绪,无论它们是负效价还是正效价(实验5)。讨论了儿童对离散情感韵律类别识别的发展轨迹。

Adolescents’ state authenticity and inauthenticity when socialising online with a friend: Motivations in friendship 青少年与朋友在线社交时的状态真实性和不真实性:友谊的动机

Authenticity is important for psychological thriving and adolescents experiment with who they are becoming (identities) with friends, so friendships are an important relationship where state authenticity and inauthenticity (the sense of and being the real me right now, versus not the real me) occur. Recent qualitative research noted friendship motivations may be connected to adolescents’ state authenticity and inauthenticity experiences, so the current study quantitatively investigated whether motivations/regulations (intrinsic, identified, introjected, external, and amotivation) predict adolescents’ state authenticity and inauthenticity when socialising online with a friend they also know in-person. Adolescents (13–17 years old, N = 130) completed an online survey about their experience of socialising online with a friend in the past 24 hours. Two exploratory factor analyses (EFA) using polychoric matrices were conducted (n1 = 115), followed by a multiple linear regression (n2 = 108). Two EFAs were conducted, with state authenticity and inauthenticity items forming one factor, while motivation in a friendship items formed two distinct factors (autonomous motivation and controlled motivation). The regression showed autonomous motivation in a friendship predicted and explained 18% of variability in state authenticity and inauthenticity (large effect). A very large sample is required to validate and identify whether controlled motivation in a friendship (e.g., involving guilt) may have a small effect. Autonomous motivation in a friendship includes positive social values, such that friendships where autonomous motivation is present enables state authenticity, and by extension, opportunities for teens to psychologically thrive.
真实对于心理发育很重要,青少年在朋友面前会尝试成为什么样的人(身份),所以友谊是一种重要的关系,在这种关系中,状态真实和不真实(现在的感觉和做真实的我,而不是真实的我)会发生。最近的定性研究指出,友谊动机可能与青少年的状态真实性和不真实性经历有关,因此,本研究定量调查了动机/规则(内在的、识别的、内源性的、外部的和动机)是否预测青少年在与他们也认识的朋友在线社交时的状态真实性和不真实性。青少年(13-17岁,N = 130)完成了一项关于他们在过去24小时内与朋友在线社交的经历的在线调查。采用多元矩阵进行两次探索性因子分析(n1 = 115),然后进行多元线性回归(n2 = 108)。进行了两个EFAs,状态真实性和不真实性项目形成一个因素,而友谊项目中的动机形成两个不同的因素(自主动机和控制动机)。回归显示,友谊中的自主动机预测和解释了18%的状态真实性和不真实性变化(大效应)。需要一个非常大的样本来验证和确定友谊中的受控动机(例如,涉及内疚)是否会产生小的影响。友谊中的自主动机包括积极的社会价值,例如,存在自主动机的友谊使状态真实,进而为青少年提供心理上茁壮成长的机会。
