ABSTRACT Children’s development of executive function is a good candidate for studying cultural differences because it is a necessary capacity for becoming competent participants in cultural activities, and yet it is also likely to be shaped by culturally organized everyday experiences, with potential consequences for children’s development and learning. An ethnographically grounded study with Yucatec Maya children was conducted to explore cultural bias in existing theoretical constructs and methods. Yucatec Maya children autonomously organize their daily activities within a dense web of family social connections and work responsibilities. Yet small pilot samples of 4- to 8-year-olds were uninterested in and performed poorly on many traditional measures of EF due to a number of cultural assumptions inherent in the tasks’ logic and demands. Specific cultural road blocks were identified, including assumptions about motivation, task meaning, rules of social interaction, and specific cultural beliefs. Several novel tasks were then developed, comprised of contextually situated, goal-driven tasks, that children were more motivated to engage in. To check on the accuracy of our analysis we propose a design for a future comparative study consisting of a mix of traditional tasks (both culturally interpretable and culturally inappropriate for Yucatec Maya children), and novel, contextually embedded tasks that were engaging for Yucatec Maya children. We close with a cost/benefit analysis of using culturally meaningful research to study children’s development.
儿童执行功能的发展是研究文化差异的一个很好的候选对象,因为它是成为称职的文化活动参与者的必要能力,但它也可能受到文化组织的日常经历的影响,对儿童的发展和学习具有潜在的影响。本研究以尤卡泰克玛雅儿童为研究对象,以人种学为基础,探讨现有理论建构和方法中的文化偏见。尤卡泰克玛雅儿童在一个由家庭、社会关系和工作责任组成的密集网络中自主组织他们的日常活动。然而,由于任务逻辑和要求中固有的一些文化假设,4至8岁儿童的小规模试点样本对许多传统的EF测量方法不感兴趣,而且表现不佳。具体的文化障碍被确定,包括对动机、任务意义、社会互动规则和特定文化信仰的假设。然后开发了一些新颖的任务,包括情境定位,目标驱动的任务,孩子们更有动力参与。为了检验我们分析的准确性,我们提出了一种未来比较研究的设计,包括传统任务(对尤卡坦玛雅儿童来说,既可以在文化上解释,也可以在文化上不合适)和新颖的、情境嵌入的任务,这些任务对尤卡坦玛雅儿童来说很有意义。最后,我们对使用具有文化意义的研究来研究儿童发展的成本/收益进行了分析。

The Development of Executive Function: Mechanisms of Change and Functional Pressures 执行职能的发展:变革机制与职能压力
IF 2.1 2区 心理学 Q3 PSYCHOLOGY, DEVELOPMENTAL Pub Date : 2023-01-05 DOI: 10.1080/15248372.2022.2160719

ABSTRACT This developmental account of executive function (EF) argues that domain-general analogical processes build a functional hierarchy of skills, which vary on a continuum of abstraction, and become increasingly differentiated over time. The paper begins by showing how a functional hierarchy can capture important aspects of EF development, including incrementalism, partial differentiation, and a shift from reactive to proactive control. It then details how children construct this hierarchy in development, by showing how they make functional analogies between similar EF problems, in a bottom-up incremental fashion. This results in EF structure which becomes differentiated into components which are more suited to solving some goal-directed problems than others. The developmental implications of this are that children eventually acquire task-general EFs while also retaining goal-specific skills sensitive to wider beliefs, values, norms, preferences, relevant motor, procedural, and embodied knowledge. There is discussion of how this approach is similar to and different from existing accounts, and how it relates to broader issues of training and transfer, group and individual differences, overlapping EF functions and domain-general learning. The developmental mechanisms advocated under this account intentionally draw on neuropsychological, learning and cognitive processes that have been demonstrated in other domains, so that EF theory can benefit from the lessons learned elsewhere and become more integrated with other areas of cognition.
执行功能(EF)的发展解释认为,领域通用类比过程建立了技能的功能层次结构,这些技能在抽象连续体上变化,并随着时间的推移变得越来越分化。本文首先展示了功能层次结构如何能够捕捉EF发展的重要方面,包括渐进主义、部分分化,以及从被动控制到主动控制的转变。然后,通过展示他们如何以自下而上的增量方式在类似的EF问题之间进行功能类比,详细说明儿童如何在发展中构建这种层次结构。这导致EF结构分化为更适合解决某些目标导向问题的组件,而不是其他组件。这对发展的影响是,儿童最终获得了任务一般性ef,同时也保留了对更广泛的信念、价值观、规范、偏好、相关的运动、程序和具体化知识敏感的目标特定技能。本文还讨论了这种方法与现有方法的相似和不同之处,以及它如何与更广泛的培训和转移、群体和个体差异、重叠的EF功能和领域一般学习等问题联系起来。这一理论所提倡的发展机制有意地借鉴了在其他领域已经被证明的神经心理学、学习和认知过程,因此EF理论可以从其他领域的经验教训中受益,并与其他认知领域更加融合。

ABSTRACT This research investigates positive future expectancies, particularly hope in children, which is comprised of agency thinking, perceiving oneself as capable of achieving goals, and pathways thinking, perceiving oneself as capable of discovering methods toward the desired goals. Two studies (n = 82) were conducted in the United States to examine the role of agency and pathways thinking in children’s trait and state happiness based on children’s self-reports and their parents reports of their children. In Study 1, dyads of typically developing children (Mage = 10.21 years) and their parents (Mage = 43.84 years) completed measures of hope and happiness. Study 2 extended Study 1 to include a diverse sample of children with chronic health conditions (Mage = 11.14 years) and their parents (Mage = 43.48 years). In Study 1, regression analyses revealed that children’s self-reports of agency thinking predict children’s trait and state happiness, p’s < .05. Contrastingly, in Study 2, regression analyses revealed that children’s self-reports of pathways thinking predict children’s self-reports of trait happiness, p < .001. Also, collectively, pathways thinking, agency thinking, and children’s age predict children’s state happiness, p = .025. In both studies, parents’ reports of their children’s hope were not significant predictors of children’s happiness. There also was not an association between parents’ perceptions of their children’s hope and happiness and their children’s self-reported levels. These findings elucidate the cognitive aspects of hope that promote happiness in childhood and advance understanding of the determinants of children’s happiness in the U.S.
本研究探讨了儿童对未来的积极期望,特别是希望,它包括代理思维,即认为自己有能力实现目标,以及路径思维,即认为自己有能力找到实现预期目标的方法。在美国进行了两项研究(n = 82),以儿童的自我报告和父母对孩子的报告为基础,研究代理思维和路径思维在儿童特质和状态幸福中的作用。在研究1中,正常发育的儿童(年龄10.21岁)和他们的父母(年龄43.84岁)完成了希望和幸福的测量。研究2扩展了研究1,纳入了患有慢性健康状况的儿童(年龄为11.14岁)及其父母(年龄为43.48岁)的不同样本。在研究1中,通过回归分析发现,儿童代理思维的自我报告对儿童的特质和状态幸福有预测作用,p < 0.05。而在研究2中,回归分析显示儿童的路径思维自我报告可以预测儿童的特质幸福自我报告,p < 0.001。此外,总的来说,路径思维、代理思维和儿童年龄预测儿童的状态幸福,p = 0.025。在这两项研究中,父母对孩子的希望的报告并不能显著地预测孩子的幸福。父母对孩子的希望和幸福的看法与孩子自我报告的水平之间也没有联系。这些发现阐明了希望的认知方面,它促进了童年的幸福,并促进了对美国儿童幸福决定因素的理解

An Ecological Systems Perspective on Individual Differences in Children’s Performance on Measures of Executive Function 儿童执行功能个体差异的生态系统视角
IF 2.1 2区 心理学 Q3 PSYCHOLOGY, DEVELOPMENTAL Pub Date : 2022-12-23 DOI: 10.1080/15248372.2022.2160721

ABSTRACT The predictive validity of performance on cognitive-behavioral measures of executive function (EF) suggests that these measures index children’s underlying capacity for self-regulation. In this paper, we apply ecological systems theory to critically evaluate this assertion. We argue that as typically administered, standard measures of EF do not index children’s underlying, trait-like capacity for EF, but rather assess their state-like EF performance at a given point in time and in a particular (and often quite peculiar) context. This underscores the importance of disentangling intra-individual (i.e., state-like) and inter-individual (trait-like) differences in performance on these measures and understanding how factors at various levels of organization may contribute to both. To this end, we offer an approach that combines the collection of repeated measures of EF with a multilevel modeling framework, and conclude by discussing the application of this approach to the study of educational interventions designed to foster children’s EF.
摘要执行功能认知行为测量结果的预测有效性表明,这些测量指标反映了儿童潜在的自我调节能力。在本文中,我们应用生态系统理论来批判性地评价这一论断。我们认为,通常情况下,EF的标准测量并没有衡量儿童潜在的、特质般的EF能力,而是评估他们在特定时间点和特定(通常非常特殊)环境下的EF表现。这强调了理清个体内部(即状态型)和个体间(特质型)在这些衡量标准上的表现差异的重要性,并理解组织各个层面的因素如何对这两者产生影响。为此,我们提供了一种方法,将EF的重复测量集合与多层次建模框架相结合,并通过讨论该方法在旨在培养儿童EF的教育干预研究中的应用来结束。

A First Theoretical Model of Self-Directed Cognitive Control Development 自我定向认知控制发展的第一个理论模型
IF 2.1 2区 心理学 Q3 PSYCHOLOGY, DEVELOPMENTAL Pub Date : 2022-12-21 DOI: 10.1080/15248372.2022.2160720

ABSTRACT Cognitive control (also referred to as executive functions) corresponds to a set of cognitive processes that support the goal-directed regulation of thoughts and actions. It plays a major role in complex activities and predicts later academic achievement. Importantly, while growing up, children are progressively transitioning from engaging cognitive control in an externally driven fashion, i.e., relying on external guidance, to exerting it self-directedly, i.e., autonomously determining when and how to engage it. Although growing self-directedness in cognitive control engagement is critical to autonomy gains during childhood, relatively little is known about the underlying cognitive mechanisms. Incorporating previous main proposals in cognitive control development, we propose that self-directed control development is driven by the ability to identify relevant goals, facilitated through accumulated knowledge on how to engage cognitive control with age. Importantly, we argue that there are two key processes that are part of successful goal identification: context-tracking and goal selection. We argue that most developmental changes are linked to context-tracking as the demands on this process are particularly high in self-directed situations. We then derived main predictions from this theoretical model as well as promising future directions.
摘要认知控制(也称为执行功能)对应于一组认知过程,支持以目标为导向的思想和行动调节。它在复杂的活动中发挥着重要作用,并预示着以后的学术成就。重要的是,在成长过程中,儿童正在从以外部驱动的方式参与认知控制,即依赖外部指导,逐渐过渡到自我指导,即自主决定何时以及如何参与。尽管在认知控制参与中培养自我指导性对儿童期获得自主性至关重要,对潜在的认知机制知之甚少。结合先前关于认知控制发展的主要建议,我们提出,自我导向的控制发展是由识别相关目标的能力驱动的,通过积累关于如何随着年龄的增长进行认知控制的知识来促进。重要的是,我们认为有两个关键过程是成功识别目标的一部分:上下文跟踪和目标选择。我们认为,大多数发展变化都与情境跟踪有关,因为在自我导向的情况下,对这一过程的要求特别高。然后,我们从这个理论模型中得出了主要的预测以及有前景的未来方向。

Reconciling the Context-Dependency and Domain-Generality of Executive Function Skills from a Developmental Systems Perspective 从发展系统的角度协调执行功能技能的情境依赖性和领域通用性

ABSTRACT Executive function (EF) skills are a set of attention-regulation skills involved in intentional, goal-directed behavior that include (but are not limited to) the cool EF skills of working memory, cognitive flexibility, and inhibitory control, and also the hot EF skill of intentional reevaluation. These skills are inevitably expressed in goal- and context-dependent ways, leading some to view EF skills as specific adaptations to particular problems and reinforcing interest in the use of more ecologically contextualized assessments. Appreciation of the context-dependency of EF skills adds to our understanding of how EF skills develop as a consequence of particular experiences and how they contribute to key developmental outcomes. There are good reasons, however, to view EF skills as relatively domain-general neurocognitive skills. Measured using standardized direct behavioral assessments, these skills are associated reliably with well-defined but distinct neural networks; they predict long-term developmental outcomes; and they can be trained in ways that produce far transfer. We argue that developmental systems models of EF skills can reconcile views of EF skills as relatively domain-general and views that emphasize the context-dependency of these skills. Ecologically adapted measures of EF skills can complement standardized measures that capture important age-related and individual differences and should remain a cornerstone of research on the topic. We believe this type of model will facilitate a deeper understanding of how multiple, simultaneous, and interacting causal influences, operating at many levels of analysis (cultural, social, cognitive, neural, and molecular), work together to produce conscious control.
执行功能(Executive function, EF)技能是一组涉及有意的、目标导向行为的注意调节技能,包括(但不限于)工作记忆、认知灵活性和抑制控制等冷EF技能,以及有意重评价等热EF技能。这些技能不可避免地以目标和环境依赖的方式表达,导致一些人将环境教育技能视为对特定问题的特定适应,并加强了对使用更多生态环境评估的兴趣。了解英孚技能的情境依赖性有助于我们理解英孚技能是如何通过特殊经历发展起来的,以及它们如何促进关键的发展结果。然而,有充分的理由将EF技能视为相对通用的神经认知技能。使用标准化的直接行为评估来衡量,这些技能与定义良好但独特的神经网络可靠地联系在一起;它们预测了长期的发展结果;他们可以被训练成远距离迁移。我们认为,英语学习技能的发展系统模型可以调和英语学习技能是相对普遍的观点和强调这些技能的情境依赖性的观点。EF技能的生态适应性测量可以补充捕捉重要的年龄相关和个体差异的标准化测量,并应继续成为该主题研究的基石。我们相信这种类型的模型将有助于更深入地理解多重、同时和相互作用的因果影响,在许多分析层面(文化、社会、认知、神经和分子)上运作,共同产生有意识的控制。

Age-related Changes in Task Switching Costs in Middle Childhood 儿童中期任务转换成本的年龄相关变化

ABSTRACT Cognitive flexibility refers to the ability to rapidly and accurately switch between tasks. It is regarded as a core dimension of executive functions and has been reported to improve during childhood and into early adulthood. For its evaluation, the task-switching paradigm is widely used. Switching between tasks or response sets imposes a series of costs on performance (i.e., mixing costs, global switch costs, local switch costs). There is less evidence analyzing switching performance in children than in other age groups, and few studies have specifically analyzed switching costs only in school-age children. In the present study, we aimed to analyze age-related changes in task switching in children aged 9–12 years old. We considered year-to-year changes in performance, specifically in response time based mixing costs, global switch costs, and local switch costs. To do this, we used a task switching measure to evaluate 231 children in Argentina, aged 9–12 years (M age = 10.94, SD = 0.88) who were aggregated into four age groups (9, 10, 11, and 12 years old). Results show consistent mixing costs, global switch costs, and local switch costs at each age. However, we did not find age-related differences in the magnitude of such costs. These results suggest that both the ability to maintain and select between two tasks, and to switch from one response set to another could be considered relatively constant during this period.
认知灵活性是指在不同任务之间快速准确切换的能力。它被认为是执行功能的一个核心方面,据报道,在童年和成年早期,它会得到改善。对于其评价,任务转换范式得到了广泛的应用。在任务或响应集之间切换会给性能带来一系列成本(即混合成本、全局切换成本、本地切换成本)。与其他年龄组相比,分析儿童转换表现的证据较少,而且很少有研究专门分析学龄儿童的转换成本。在本研究中,我们旨在分析9-12岁儿童任务转换的年龄相关变化。我们考虑了性能的逐年变化,特别是基于混合成本、全局切换成本和本地切换成本的响应时间变化。为了做到这一点,我们使用任务转换测量来评估阿根廷9 - 12岁的231名儿童(M年龄= 10.94,SD = 0.88),他们被分为四个年龄组(9岁、10岁、11岁和12岁)。结果显示,混合成本、全球转换成本和本地转换成本在每个年龄段都是一致的。然而,我们没有发现这些成本的大小与年龄相关的差异。这些结果表明,在这段时间内,维持和选择两个任务的能力,以及从一个响应集切换到另一个响应集的能力都可以被认为是相对恒定的。

There is less evidence analyzing switching performance in children than in other age groups, and few studies have specifically analyzed switching costs only in school-age children.

We considered year-to-year changes in performance, specifically in response time based mixing costs, global switch costs, and local switch costs. To do this, we used a task switching measure to evaluate 231 children in Argentina, aged 9–12 years (M age = 10.94, SD = 0.88) who were aggregated into four age groups (9, 10, 11, and 12 years old).

Young Children’s Saving and Their Episodic Future Thinking 幼儿储蓄与情景未来思维

ABSTRACT Children’s ability to save emerges during the preschool years, but little is known about the different forms saving takes (and whether these relate) and the mechanisms driving its development. Because research with adults suggests that different aspects of future orientation increase adults’ propensity to save, we explored whether, in a sample of 71 3- to 5-year-olds tested in a university laboratory in Ottawa, Canada, the ability to mentally pre-experience the future (or “episodic future thinking”) predicted saving in two different contexts. In the first, using a “Saving marbles” task, we assessed children’s capacity to save for a larger reward in the near future. In the second, using a newly developed “Saving candies” task, we assessed children’s capacity to save a certain amount of resource for a more remote future time point, without necessarily reaping a larger future reward. Children were also given two delay of gratification tasks to determine whether these related to saving. Performance on both saving tasks was significantly related after controlling for age in months and verbal ability (r = .25, p = .041), a finding that suggests some coherence in early saving behaviors. However, we detected no significant associations between saving and delay of gratification. A series of regression analyses showed that episodic future thinking, as measured by three different tasks, did not predict saving. Our discussion focuses on why the capacity to think about the future may not predict saving in early development, and suggests viable avenues for future research in this area.
儿童的储蓄能力在学龄前就开始显现,但人们对储蓄的不同形式(以及这些形式是否相关)和驱动其发展的机制知之甚少。由于对成年人的研究表明,未来取向的不同方面会增加成年人的储蓄倾向,我们在加拿大渥太华的一所大学实验室对71名3至5岁的儿童进行了测试,研究了在两种不同情况下,心理上预先体验未来的能力(或“情景未来思维”)是否能预测储蓄。在第一个实验中,我们用“保存弹珠”的任务来评估孩子们为在不久的将来获得更大的奖励而存钱的能力。在第二个实验中,我们使用了一个新开发的“节省糖果”任务,我们评估了孩子们为更遥远的未来时间点节省一定数量资源的能力,而不一定会获得更大的未来奖励。孩子们还被分配了两个延迟满足的任务,以确定这些任务是否与储蓄有关。在控制了月龄和语言能力后,两项储蓄任务的表现显著相关(r = 0.25, p = 0.041),这一发现表明早期储蓄行为存在一定的一致性。然而,我们发现储蓄和延迟满足之间没有显著的联系。一系列的回归分析表明,通过三个不同的任务来衡量的情景性未来思维并不能预测储蓄。我们的讨论集中在为什么思考未来的能力可能无法预测早期发展中的储蓄,并为该领域的未来研究提出了可行的途径。

Children’s Sensitivity to Difficulty and Reward Probability When Deciding to Take on a Task 儿童在决定承担任务时对困难的敏感性和奖励概率
IF 2.1 2区 心理学 Q3 PSYCHOLOGY, DEVELOPMENTAL Pub Date : 2022-12-12 DOI: 10.1080/15248372.2022.2152032

ABSTRACT Sometimes we should persist to succeed. But other times it might be wiser to give up on the task at hand and focus our energy on something new. Knowing whether a task is worth the effort potentially requires multiple capacities, including sensitivity to one’s own likelihood to succeed on the current problem, the associated costs with continuing to pursue it, and evaluation of opportunities for reward from the success. But these capacities may be particularly challenging for young children. Here we ask how young children are sensitive to cognitive cost (one’s capacity and the opportunity cost of persisting) and reward probability (how likely they are to receive a reward when succeeding) when making decisions. Using a simple counting task, we showed that 4- to 5-year-old children in the US (N = 40, pre-registered) chose to give up more when the task was more difficult (and therefore cognitively more costly), especially when the probability of reward was low. These results extend previous findings and suggest the ability to consider and evaluate cognitive cost and reward probability may be in place by 4 years of age.
有时候我们需要坚持才能成功。但其他时候,放弃手头的任务,把精力集中在新的事情上可能是更明智的。了解一项任务是否值得付出努力可能需要多种能力,包括对自己在当前问题上取得成功的可能性的敏感性,继续追求它的相关成本,以及对成功获得回报的机会的评估。但这些能力对幼儿来说可能尤其具有挑战性。在这里,我们询问幼儿在做决定时对认知成本(一个人的能力和坚持的机会成本)和奖励概率(他们成功后获得奖励的可能性)有多敏感。通过一个简单的计数任务,我们发现美国4- 5岁的儿童(N = 40,预注册)在任务难度更高(因此认知成本更高)时,特别是在获得奖励的可能性较低的情况下,选择放弃的可能性更大。这些结果扩展了先前的研究结果,并表明考虑和评估认知成本和奖励概率的能力可能在4岁之前就已经具备了。

ABSTRACT The development of children’s future-oriented cognition has become a popular research topic in the past two decades. Much of this research focuses on the preschool and middle childhood years, but very little is known about the future-oriented cognitive abilities of toddlers and young preschoolers. The present study investigated the emergence of future-oriented cognition in toddlerhood and explored its relation with cognitive (i.e., executive function, episodic memory, and self-concept) and language abilities (i.e., expressive vocabulary, parent-child talk, temporal word use, and time metaphor use). Parents (N = 205) of 2- to 3-year-old children residing in the United States participated in an online study in which they completed the Children’s Future Thinking Questionnaire (CFTQ) to assess their child’s future-oriented cognition in five key domains. Also, parent-report measures of executive function, self-concept, episodic memory, expressive vocabulary, parent-child talk, child’s temporal word use, and child’s use of time metaphors were administered. Children as young as 2-years-old demonstrated future-oriented abilities. However, parents of 2-year-olds had substantial missing data (e.g., “does not apply”), especially in the planning and prospective memory subscales of the CFTQ. Three-year-olds were rated higher than 2-year-olds on the planning and prospective memory subscales, but there were no differences in ratings for 2- and 3-year-olds on the saving, episodic foresight, and delay of gratification subscales. Episodic memory and time metaphor use were significant independent predictors of future-oriented cognition and thus, both abilities may play a fundamental role in the emergence of future-oriented cognition in young children.
摘要近二十年来,儿童未来认知的发展已成为一个热门的研究课题。这项研究大多集中在学龄前和儿童中期,但对学步儿童和学龄前儿童的未来认知能力知之甚少。本研究调查了幼儿期未来导向认知的出现,并探讨了其与认知(即执行功能、情景记忆和自我概念)和语言能力(即表达词汇、亲子对话、时间词汇使用和时间隐喻使用)的关系。居住在美国的2至3岁儿童的父母(N=205)参加了一项在线研究,他们完成了儿童未来思维问卷(CFTQ),以评估孩子在五个关键领域的未来认知。此外,还对执行功能、自我概念、情景记忆、表达性词汇、亲子对话、儿童的时态词汇使用和儿童对时间隐喻的使用进行了家长报告测量。2岁的孩子就表现出了面向未来的能力。然而,2岁儿童的父母有大量缺失的数据(例如,“不适用”),尤其是在CFTQ的计划和前瞻性记忆分量表中。三岁儿童在计划和前瞻记忆分量表上的评分高于2岁儿童,但2岁和3岁儿童在储蓄、情景预见和满足延迟分量表上没有差异。情节记忆和时间隐喻的使用是面向未来认知的重要独立预测因素,因此,这两种能力可能在幼儿出现面向未来认知中发挥重要作用。
