    父母可以促进幼儿的早期数学和识字能力。然而,父母信念的差异会影响他们在亲子互动中的行为。我们研究了父母对儿童数学和阅读能力的固定性的信念如何在教育活动中影响他们与4岁和5岁儿童的互动。父母对儿童能力的信念是使用“文章”操纵的,表明学术能力在一个领域是固定的(例如,数学),但在另一个中具有延展性(例如,reading).然后,我们调查了父母在不同条件下的非建设性(以绩效为导向和控制)和建设性(以掌握为导向和自治支持)参与的差异。我们还检查了父母的行为是否根据父母被告知活动的教育材料的类型而有所不同。结果表明,被诱导对阅读有固定心态的父母比被诱导对阅读有成长心态的父母更经常地完全控制阅读活动,但不是数学。父母在两个领域的心态诱导条件之间的建设性参与没有差异。我们还发现,父母在数学中的自主行为取决于父母的智力信念的一般理论。总的来说,我们发现了一些证据,表明父母对孩子在特定领域的能力的延展性的信念影响了他们在该领域的行为。
    Parents can be instrumental in promoting young children\'s early mathematics and literacy skills. However, differences in parents\' beliefs can influence their behavior during parent-child interactions. We examined how parental beliefs about the fixedness of children\'s math and reading abilities shape their interactions with their 4- and 5-year-old children during an educational activity. Parental beliefs about children\'s abilities were manipulated using \"articles\" indicating that academic ability is fixed in one domain (e.g., math) but malleable in another (e.g., reading). We then investigated differences in parental unconstructive (performance-oriented and controlling) and constructive (mastery-oriented and autonomy-supportive) involvement across conditions. We also examined whether parent behavior differed depending on the type of educational material parents were told the activity tapped into. The results showed that parents who were induced to have a fixed mindset about reading took full control of the reading activity more often than those who were induced to have a growth mindset about reading, but not math. Parents did not differ in constructive involvement between mindset induction conditions in either domain. We also found that parent autonomy behavior in math differed depending on parents\' general theory of intelligence beliefs. Overall, we found some evidence that parents\' beliefs about the malleability of their children\'s ability in a specific domain affected their behaviors in that domain.

    数字认知是一个研究社会文化的领域,发展,认知,和生物学方面的数学能力。认知神经科学的最新发现表明,认知技能是由分布式,瞬态,大脑中的动态网络,而不是孤立的功能模块。Further,对认知的身体和进化基础的研究表明,我们的认知技能利用能力最初是为行动而进化的,并且最好将认知与感知运动能力结合起来理解。尽管有这些见解,数字认知的神经模型努力捕捉数学技能和感知运动系统之间的关系。解决这个问题的一个方面是识别大脑中支持数字技能的积木感觉运动过程(BBP),并开发一种将感觉运动系统与数学认知联系起来的新本体。这里的BBP被确定为感觉运动功能,与大脑中的分布式网络相关联,并一致被认为支持不同的认知能力。BBP可以通过神经影像学的新方法来识别;通过检查实验设计中的一系列感觉运动和认知任务,采用数据驱动的信息学方法来识别支持认知过程的感觉运动网络,并考虑数学能力的进化和身体基础来解释结果。关于BBP的新经验见解最终可以导致数字认知中的具体化认知本体论。在其他数学技能中,讨论了数值幅度处理及其感觉运动的起源,以证实所提出的论点。此外,提供了功能磁共振成像研究设计,以说明实证研究中提出的论点的应用。
    Numerical cognition is a field that investigates the sociocultural, developmental, cognitive, and biological aspects of mathematical abilities. Recent findings in cognitive neuroscience suggest that cognitive skills are facilitated by distributed, transient, and dynamic networks in the brain, rather than isolated functional modules. Further, research on the bodily and evolutionary bases of cognition reveals that our cognitive skills harness capacities originally evolved for action and that cognition is best understood in conjunction with perceptuomotor capacities. Despite these insights, neural models of numerical cognition struggle to capture the relation between mathematical skills and perceptuomotor systems. One front to addressing this issue is to identify building block sensorimotor processes (BBPs) in the brain that support numerical skills and develop a new ontology connecting the sensorimotor system with mathematical cognition. BBPs here are identified as sensorimotor functions, associated with distributed networks in the brain, and are consistently identified as supporting different cognitive abilities. BBPs can be identified with new approaches to neuroimaging; by examining an array of sensorimotor and cognitive tasks in experimental designs, employing data-driven informatics approaches to identify sensorimotor networks supporting cognitive processes, and interpreting the results considering the evolutionary and bodily foundations of mathematical abilities. New empirical insights on the BBPs can eventually lead to a revamped embodied cognitive ontology in numerical cognition. Among other mathematical skills, numerical magnitude processing and its sensorimotor origins are discussed to substantiate the arguments presented. Additionally, an fMRI study design is provided to illustrate the application of the arguments presented in empirical research.

    人脑拥有神经网络和能够表示数字的机制,基本的算术运算,数学推理。没有表示数字量和进行计算的能力,我们的科学和技术先进的文化将不存在。然而,数字能力的起源是基于对生物学中根深蒂固的数量的直观理解。然而,更高级的符号算术技能需要具有正规数学教育的文化背景。在过去的二十年里,认知神经科学在通过各种方法和模型系统理解计算大脑的运作方面取得了重大进展。这篇综述首先探讨了非符号数字量的心理和神经元表示,然后发展到童年时期获得的符号表示。在算术运算期间(加法,减法,乘法,和划分),这些表示根据算术规则和原理进行处理和转换,利用不同的心理策略和可以在大脑中分离的算术知识类型。虽然人们曾经认为数字处理和计算起源于语言学院,现在很明显,数学和语言能力主要是在大脑中独立处理的。了解健康的大脑如何处理数字信息对于了解使人衰弱的数字障碍至关重要,包括获得性疾病,如无症状和与学习相关的计算障碍,如发育性计算障碍。
    The human brain possesses neural networks and mechanisms enabling the representation of numbers, basic arithmetic operations, and mathematical reasoning. Without the ability to represent numerical quantity and perform calculations, our scientifically and technically advanced culture would not exist. However, the origins of numerical abilities are grounded in an intuitive understanding of quantity deeply rooted in biology. Nevertheless, more advanced symbolic arithmetic skills necessitate a cultural background with formal mathematical education. In the past two decades, cognitive neuroscience has seen significant progress in understanding the workings of the calculating brain through various methods and model systems. This review begins by exploring the mental and neuronal representations of non-symbolic numerical quantity, then progresses to symbolic representations acquired in childhood. During arithmetic operations (addition, subtraction, multiplication, and division), these representations are processed and transformed according to arithmetic rules and principles, leveraging different mental strategies and types of arithmetic knowledge that can be dissociated in the brain. While it was once believed that number processing and calculation originated from the language faculty, it is now evident that mathematical and linguistic abilities are primarily processed independently in the brain. Understanding how the healthy brain processes numerical information is crucial for gaining insights into debilitating numerical disorders, including acquired conditions like acalculia and learning-related calculation disorders such as developmental dyscalculia.

    许多研究报告说,晚上的人学业成绩差,认知的一般昼夜节律波动。这项研究的目的是分析横截面设计中的昼夜节律波动,并研究时间型对情境情绪和内在动机的影响。在三所土耳其中学进行了一项横断面调查研究,共抽样599名学生(283名女性和316名男性)。数据是在相同年级和内容的特定数学课结束时收集的,使用结合三个尺度的形式。我们发现内在动机没有性别相关的差异,而情境动机存在一些差异。在数学课上,女学生表现出更高的兴趣,而男孩在无聊方面得分更高。此外,早上得分高的学生会报告更高的兴趣水平,幸福,更少的无聊。具有较高稳定性(以及白天情绪和认知波动较低)的学生报告了更高的享受程度,感知能力,感知的选择,和较少的压力/紧张的数学课。在清晰度之间观察到正相关,兴趣,和幸福,而鲜明与无聊之间存在负相关。这表明昼夜稳定性较高的学生表现出更高的兴趣,幸福,和较低的无聊程度。此外,分析结果表明,早晨,清晰度,和晚上是内在动机的重要预测因子。相反,性别,申请时间,早晨,和独特性成为数学课中情境情绪的预测因子。
    Many studies have reported poor school achievement in evening persons and general circadian fluctuations in cognition. The aim of this study was to analyze circadian fluctuations in a cross-sectional design and examine the effects of chronotype on situational emotions and intrinsic motivation. A cross-sectional survey study was conducted in three Turkish secondary schools with a total sample of 599 students (283 females and 316 males). Data were collected at the end of specific math lessons of the same grade level and content, using a form combining three scales. We found no gender-related differences in intrinsic motivation, while there were some differences in situational motivation. In math classes, female students exhibited higher level of interest, while boys scored higher on boredom. In addition, students who scored high on morning affect reported higher levels of interest, well-being, and less boredom. Students with higher stability (and lower fluctuations in mood and cognition during the day) reported a higher degree of enjoyment, perceived competence, perceived choice, and less pressure/tension in their math lessons. A positive association was observed between distinctness, interest, and well-being, while negative correlations existed between distinctness and boredom. This suggests that students with higher diurnal stability reported a higher level of interest, well-being, and a lower level of boredom. Additionally, the results of the analyses showed that morningness, distinctness, and eveningness were significant predictors of intrinsic motivation. Conversely, gender, time of application, morningness, and distinctness emerged as predictors for situational emotions in mathematics classes.

    数学运算是我们用来计算数字之间关系的认知行为。算术运算,addition,减法,乘法,分裂是教育的基础。加法是学校教授的第一个加法,在功能磁共振成像(fMRI)研究中最受欢迎。司,通常最后教的是功能磁共振成像研究最少。fMRI荟萃分析表明,算术运算激活顶叶的大脑区域,儿童和成人的扣带和岛状皮质。严重的,没有荟萃分析检查儿童和成人单独算术运算的大脑相关性之间的一致性。我们使用功能磁共振成像文章的定量荟萃分析数据进行审查和检查,这些文章分别报告了大脑坐标,减法,乘法,儿童和成人的分工。结果表明,算术运算在成人和儿童的额顶叶和扣带眼网络中引起共同的一致区域。手术之间的差异主要是针对成年人。有趣的是,更高的群体内部一致性,以激活可能性估计表示,在儿童的大脑区域中发现了与扣带眼网络相关的大脑区域,而不是额叶-顶叶网络,成人和儿童之间也很常见。讨论了与建构主义认知理论和未来研究的实践方向有关的发现。
    Mathematical operations are cognitive actions we take to calculate relations among numbers. Arithmetic operations, addition, subtraction, multiplication, and division are elemental in education. Addition is the first one taught in school and is most popular in functional magnetic resonance imaging (fMRI) studies. Division, typically taught last is least studied with fMRI. fMRI meta-analyses show that arithmetic operations activate brain areas in parietal, cingulate and insular cortices for children and adults. Critically, no meta-analysis examines concordance across brain correlates of separate arithmetic operations in children and adults. We review and examine using quantitative meta-analyses data from fMRI articles that report brain coordinates separately for addition, subtraction, multiplication, and division in children and adults. Results show that arithmetic operations elicit common areas of concordance in fronto-parietal and cingulo-opercular networks in adults and children. Between operations differences are observed primarily for adults. Interestingly, higher within-group concordance, expressed in activation likelihood estimates, is found in brain areas associated with the cingulo-opercular network rather than the fronto-parietal network in children, areas also common between adults and children. Findings are discussed in relation to constructivist cognitive theory and practical directions for future research.

    基于设计的STEM学习被认为是促进儿童认知发展的有效跨学科策略。然而,它对执行职能的影响,特别是对于弱势儿童,仍然需要探索。本研究调查了基于短期强化设计的STEM学习对留守儿童执行功能的影响。从中国一所致力于留守儿童的学校抽取61名四年级学生,随机分配到实验组(10.70±0.47岁,n=30)或对照组(10.77±0.43岁,n=31)。实验组进行了为期两周的基于设计的STEM培训计划,而对照组参加了为期2周的STEM相关阅读计划。在训练前后的Stroop任务期间,使用功能近红外光谱(fNIRS)和行为措施对两组进行了4个感兴趣的大脑区域的大脑激活评估。分析显示:(i)实验组有显著的组内时间效应,在中性和单词条件下,Brodmann区10和46的测试后脑激活显着降低;(ii)在测试后显着的组间差异,实验组在Brodmann区10和Brodmann区46中的脑激活明显低于对照组;(iii)在Stroop任务的三个条件中,脑活动的任务效应显着。这些发现表明,这种STEM学习有效地增强了留守儿童的执行功能。行为表现的非显着差异与大脑激活的显着差异之间的差异暗示着大脑激活的代偿机制。这项研究丰富了当前关于科学影响的理论,技术,Engineering,和数学(STEM)学习对儿童执行功能发展的影响,为教育课程设计和评估提供生物学证据和有价值的见解。
    Design-based STEM learning is believed to be an effective cross-disciplinary strategy for promoting children\'s cognitive development. Yet, its impact on executive functions, particularly for disadvantaged children, still need to be explored. This study investigated the effects of short-term intensive design-based STEM learning on executive function among left-behind children. Sixty-one Grade 4 students from a school dedicated to the left-behind children in China were sampled and randomly assigned to an experimental group (10.70 ± 0.47 years old, n = 30) or a control group (10.77 ± 0.43 years old, n = 31). The experimental group underwent a two-week design-based STEM training program, while the control group participated in a 2-week STEM-related reading program. Both groups were assessed with the brain activation from 4 brain regions of interest using functional near-infrared spectroscopy (fNIRS) and behavioral measures during a Stroop task before and after the training. Analysis disclosed: (i) a significant within-group time effect in the experimental group, with posttest brain activation in Brodmann Area 10 and 46 being notably lower during neutral and word conditions; (ii) a significant between-group difference at posttest, with the experimental group showing considerably lower brain activation in Brodmann Area 10 and Brodmann Area 46 than the control group; and (iii) a significant task effect in brain activity among the three conditions of the Stroop task. These findings indicated that this STEM learning effectively enhanced executive function in left-behind children. The discrepancy between the non-significant differences in behavioral performance and the significant ones in brain activation implies a compensatory mechanism in brain activation. This study enriches current theories about the impact of Science, Technology, Engineering, and Mathematics (STEM) learning on children\'s executive function development, providing biological evidence and valuable insights for educational curriculum design and assessment.

    目的:青少年时期的同伴关系在塑造学业成绩方面发挥着重要作用。本研究检查了朋友对数学情绪的影响,以及气质在这些影响中的作用。
    方法:样本包括350名芬兰学生(平均年龄13.29岁;64%的女孩),他们从7年级的秋季到春季都参与了稳定的友谊二元组合。
    方法:在这项两波研究中,关于青少年气质的信息(即,负面情绪,外向,努力控制)和对数学的七种情绪(即,享受,希望,骄傲,愤怒,焦虑,羞耻,绝望,和无聊)是在7年级收集的。使用纵向行动者-伙伴相互依存模型分析数据。
    结果:结果显示,在所有被调查的数学相关情绪中,朋友彼此相似。此外,除了这些最初的相似之处,朋友互相影响对方的数学相关的享受和愤怒对数学。以较高的负面情绪为特征的学生也影响了他们的朋友,他们的负面情绪水平较低,导致数学相关的愤怒增加,而缺乏努力的控制使青少年更容易受到朋友对数学相关的羞耻和焦虑的影响。
    结论:我们的研究结果表明,随着时间的推移,朋友在与数学相关的享受和挫折中相互影响。此外,高负面情绪可能会使青少年对与数学有关的朋友的愤怒更具影响力,而缺乏努力的控制可能会使青少年更容易受到与数学有关的羞耻和焦虑的朋友影响。因此,当前的发现对同伴关系如何影响数学中的个体结果有影响,更好或更糟。
    OBJECTIVE: Peer relationships during adolescence play an important role in shaping academic outcomes. The present study examined friend influences on emotions towards math, as well as the role of temperament in these influences.
    METHODS: The sample consisted of 350 Finnish students (mean age 13.29 years; 64% girls) who were involved in stable friendship dyads from fall to spring of Grade 7.
    METHODS: In this two-wave study, information on adolescents\' temperament (i.e., negative emotionality, extraversion, effortful control) and on seven emotions towards math (i.e., enjoyment, hope, pride, anger, anxiety, shame, hopelessness, and boredom) was collected during grade 7. The data were analysed using longitudinal actor-partner interdependence models.
    RESULTS: The results showed that friends resembled each other in all the investigated math-related emotions. Furthermore, over and above these initial similarities, friends mutually influenced each other\'s math-related enjoyment and anger towards math. Students characterized by higher negative emotionality also influenced their friends with lower levels of negative emotionality towards an increase in math-related anger and a lack of effortful control made adolescents more susceptible to friend influence over math-related shame and anxiety.
    CONCLUSIONS: Our findings demonstrate that friends influence each other over time in math-related enjoyment and frustration. Furthermore, high negative emotionality may make adolescents more influential over their friends\' math-related anger and a lack of effortful control may make adolescents more susceptible to friend influence over math-related shame and anxiety. Thus, the current findings have implications for how peer relations may impact individual outcomes in mathematics, for better or worse.
