La représentation du but dans le contrôle exécutif chez l’enfant

Implementation of executive control over thought and action can only be guided by the goals that one desires to reach. Over the last decade, research has pointed out the central role of goal representation in executive control both during childhood and adulthood. The present paper reviews these findings, emphasizing the developmental dynamics observed during childhood. More precisely, it addresses the role of active goal maintenance in working memory, as it has been stressed by developmental and neurocognitive theoretical models. Beyond goal maintenance, the question as to how goal representations are formed in working memory has attracted research efforts lately. With age, children successfully process increasingly subtle environmental cues to infer the current task goal and when task goals need to be updated, as evidenced by the effect of cue transparency on switching and inhibition performance. In addition, the paper addresses how goal representation sheds light on the interplay between executive skills and conceptual knowledge, through the presentation of research in such domains as analogical reasoning, categorical flexibility, and class inclusion quantification. Taken together, these lines of research show that executive control development does not rely exclusively on a growing ability to implement appropriate actions, but it also depends largely on increasingly efficient identification of what such actions should be.     

Involvement of Executive Functions in Children's Metamemory

This experiment examined how knowledge of memory strategies and of memory functioning improves during childhood and what variables are involved in this development. Three main aspects of metamemory were assessed based on the performance of a group of 100 children (aged 4, 6, 9 and 11 years) on a battery of executive tasks. At the same time, the influence of variables such as intelligence, vocabulary and parental education level was also investigated. Results of mediation analyses reveal that the relation between children's age and internal strategy knowledge was partially mediated by working memory skills but that executive functions did not mediate the impact of chronological age on children's knowledge of external strategies or of memory functioning. Additionally, verbal fluency predicted internal and external strategy knowledge. Implications for general learning theories in childhood are discussed.Copyright © 2015 John Wiley & Sons, Ltd.     

Is conditional reasoning related to mathematical problem solving?

The current study aimed to investigate the relation between conditional reasoning, which is a common type of logical reasoning, and children's mathematical problem solving. A sample of 124 fourth graders was tested for their conditional reasoning skills and their mathematical problem solving skills, as well as a list of control variables (e.g., IQ, working memory, reading) and potential mediators (number sentence construction and computation). The children's ability to make modus ponens (MP) inferences significantly predicted their mathematical problem solving skills, even after controlling for the potential confounding variables. The relation was mediated by the number sentence construction skills. The findings, in addition to supporting the link between conditional reasoning and mathematics, further indicate that the ability to process relations may be the mechanism underlying the relation. Theoretical and practical implications are discussed.     

从知觉分心任务看儿童类比推理能力的发展

采用四类图片类比映射任务,考察了知觉分心对90名4岁、5岁、6岁儿童类比推理能力发展的影响,并进一步阐释影响儿童类比推理能力发展的可能机制。四类图片类比映射任务分别为一种关系无分心任务、一种关系有分心任务、两种关系无分心任务和两种关系有分心任务。结果表明：（1）在具备相应知识经验的前提下,知觉分心对儿童类比推理成绩有显著影响,儿童在无分心任务中的表现明显好于知觉分心任务的表现。在无分心条件下,4岁儿童已经开始能够选择关系匹配来正确完成类比推理。错误分析发现知觉分心任务中儿童所犯错误主要是分心错误,而且分心错误随年龄增长呈下降趋势。这表明对知觉分心的抑制控制可能是儿童类比推理能力发展的一个重要影响因素。（2）随着年龄增长,儿童类比推理能力逐渐提高。总体表现为6岁组的成绩显著优于4岁、5岁组的成绩,而4岁组的成绩与5岁组的成绩没有显著差异。5岁可能是儿童能够抑制知觉分心进行类比推理的快速发展期     

The role of executive function and social‐emotional skills in the development of literacy and numeracy during preschool: a cross‐lagged longitudinal study

The majority of evidence on the interplay between academic and non‐academic skills comes from high‐income countries. The aim of this study was to examine the bidirectional associations between Ghanaian children's executive function, social‐emotional, literacy, and numeracy skills longitudinally. Children (N = 3,862; M age = 5.2 years at time 1) were assessed using direct assessment at three time points over the course of two school years. Controlling for earlier levels of the same skill, early executive function predicted higher subsequent literacy and numeracy skills, and early literacy and numeracy skills predicted higher subsequent executive function, indicating that the development of executive function and academic skills is inter‐related and complementary over time. Early literacy and numeracy predicted subsequent social‐emotional skills, but early social‐emotional skills did not predict subsequent literacy and numeracy skills. The findings provide longitudinal evidence on children's learning and development in West Africa and contribute to a global understanding of the relations between various developmental skills over time.     

Croyances de contrôle et rendement scolaire chez des élèves francophones du primaire au Québec

Recent research in educational psychology, both in the United States and Europe, suggested that students' control beliefs must be considered to understand interindividual variations in students' personal engagement in learning and academic achievement. The present study was conducted with 780 French-speaking elementary school children from grade four to six. The objectives were to examine: (1) the relation between dimensions of control beliefs, (2) whether there were age-related changes in children's control beliefs, and (3) the relation between control beliefs and academic achievement across school grades. Results showed that the relations between dimensions of control beliefs and children's judgements about their importance in school achievement were stable across school grades. No relation was found between children's judgements about usefulness of specific means and academic achievement, but children's beliefs about their capacity to use these means was a powerful predictor of academic achievement. The discussion focuses on similarities and dissimilarities of these findings with those of studies conducted in the United States and Europe.     

Language counts: Early language mediates the relationship between parent education and children's math ability

Children's early math skills have been hailed as a powerful predictor of academic success. Disparities in socioeconomic context, however, also have dramatic consequences on children's learning. It is therefore critical to investigate both of these distinct contributors in order to better understand the early foundations of children's academic outcomes. This study tests an integrated model of children's developing math ability so as to (1) identify the specific skills and abilities most clearly linked to early math achievement and (2) measure the influence of children's socioeconomic context on each of these skills. We first evaluated the early vocabulary, number word knowledge (knower level), and Approximate Number System (ANS) acuity of a diverse group of preschoolers. Then, approximately 1 year later as they entered Kindergarten, we administered a test of early math achievement. We find that children's early language (general vocabulary and number word knowledge) fully mediates the relationship between parent education and math ability. Additionally, number word knowledge mediates the relationship between ANS acuity and early math. We argue that increased focus on number word knowledge, as well as general vocabulary, may help to minimize disparities in math ability as children enter kindergarten. We also highlight the role of parent education on children's learning and note that this may be an important locus for intervention.     

儿童类比推理的影响因素及干预促进

Working memory as a predictor of written arithmetical skills in children: The importance of central executive functions

Background . The study was conducted in an attempt to further our understanding of how working memory contributes to written arithmetical skills in children. Aim . The aim was to pinpoint the contribution of different central executive functions and to examine the contribution of the two subcomponents of children's written arithmetical skills. Sample and method . A total of 141 third‐ and fourth‐graders were administered arithmetical tasks and measures of working memory, fluid IQ and reading. Regression analysis was used to examine the relationship between working memory and written arithmetical skills. Results . Three central executive measures (counting span, trail making and verbal fluency) and one phonological loop measure (Digit Span) were significant and predictors of arithmetical performance when the influence of reading, age and IQ was controlled for in the analysis. Conclusions . The present findings demonstrate that working memory, in general, and the central executive, in particular, contribute to children's arithmetical skills. It was hypothesized that monitoring and coordinating multiple processes, and accessing arithmetical knowledge from long‐term memory, are important central executive functions during arithmetical performance. The contribution of the phonological loop and the central executive (concurrent processing and storage of numerical information) indicates that children aged 9–10 years primarily utilize verbal coding strategies during written arithmetical performance.     

工作记忆对类比推理的影响

该实验采用2(类比推理类型)×6(组别)双因素实验设计来探讨工作记忆与类比推理之间的关系,尤其关注工作记忆的各个子成分对类比推理的影响。控制组的被试只需完成类比推理测验,而实验组的被试是在双任务的条件下进行实验。结果表明,工作记忆是影响类比推理的一个重要因素。在图形类比推理中,主要有视空间模板中的空间成分,语音回路中的发音成分以及中央执行器的参与;在言语类比推理中,则是视空间模板中的空间成分起主要作用。     

Linking executive function skills and physiological challenge response: Piecewise growth curve modeling

This study employed piecewise growth curve modeling to examine how children's executive function (EF) skills relate to different components of children's physiological response trajectory – initial arousal, reactivity, and recovery. The sample included 102 ethnically diverse kindergarteners, whose EF skills were measured using standard tasks and observer ratings. Physiological response was measured via changes in respiratory sinus arrhythmia (RSA) in response to a laboratory socio‐cognitive challenge. Children's cool and hot EF skills were differentially related to both linear and quadratic components of RSA response during the challenge. Greater hot EF skills and assessor report of EF skills during laboratory visit were related to quicker RSA recovery after the challenge. These findings demonstrate that children's physiological response is a dynamic process that encompasses physiological recovery and relates to children's self‐regulation abilities.     

The role of relational reasoning in children's addition concepts

The study addresses the relational reasoning of different‐aged children and how addition reasoning is related to problem‐solving skills within addition and to reasoning skills outside addition. Ninety‐two 5‐ to 8‐year‐olds were asked to solve a series of conceptually related and unrelated addition problems, and the speed and accuracy of all self‐reported strategies were used to monitor their addition performance. Children were also given a series of general relational reasoning tasks to assess their ability to solve problems based on thematic, causal and visual relations. The results revealed that, while children were able to reason about commutativity relations, recognition of relations based on additive composition was rare. Furthermore, children's ability to reason about addition concepts increased with age and problem‐solving proficiency. Reasoning about addition concepts was related to performance on the thematic, causal and visual reasoning tasks for older children but not for younger children. Overall, the findings suggest that while children's early knowledge of addition relations is domain specific, as children develop in their broader reasoning abilities these developments enhance their addition reasoning.     

Counting on fine motor skills: links between preschool finger dexterity and numerical skills

Finger counting is widely considered an important step in children's early mathematical development. Presumably, children's ability to move their fingers during early counting experiences to aid number representation depends in part on their early fine motor skills (FMS). Specifically, FMS should link to children's procedural counting skills through consistent repetition of finger‐counting procedures. Accordingly, we hypothesized that (a) FMS are linked to early counting skills, and (b) greater FMS relate to conceptual counting knowledge (e.g., cardinality, abstraction, order irrelevance) via procedural counting skills (i.e., one–one correspondence and correctness of verbal counting). Preschool children (N = 177) were administered measures of procedural counting skills, conceptual counting knowledge, FMS, and general cognitive skills along with parent questionnaires on home mathematics and fine motor environment. FMS correlated with procedural counting skills and conceptual counting knowledge after controlling for cognitive skills, chronological age, home mathematics and FMS environments. Moreover, the relationship between FMS and conceptual counting knowledge was mediated by procedural counting skills. Findings suggest that FMS play a role in early counting and therewith conceptual counting knowledge.     

Explaining early moral hypocrisy: Numerical cognition promotes equal sharing behavior in preschool‐aged children

Recent work has documented that despite preschool‐aged children's understanding of social norms surrounding sharing, they fail to share their resources equally in many contexts. Here we explored two hypotheses for this failure: an insufficient motivation hypothesis and an insufficient cognitive resources hypothesis. With respect to the latter, we specifically explored whether children's numerical cognition—their understanding of the cardinal principle—might underpin their abilities to share equally. In Experiment 1, preschoolers’ numerical cognition fully mediated age‐related changes in children's fair sharing. We found little support for the insufficient motivation hypothesis—children stated that they had shared fairly, and failures in sharing fairly were a reflection of their number knowledge. Numerical cognition did not relate to children's knowledge of the norms of equality (Experiment 2). Results suggest that the knowledge–behavior gap in fairness may be partly explained by the differences in cognitive skills required for conceptual and behavioral equality.     

"I GET PROUD WHEN I READ": FIRST-GRADERS TALK ABOUT READING

This interpretive research addressed five first-graders' perceptions of reading and of being readers, asking the questions: What does reading or being a reader mean to a group of children who are at the end of first grade? What are they see as its purpose? How do they view themselves as readers? The data is presented in the form of narratives describing the children and their views, followed by a discussion of the children's reading identities and purposes for reading as condensed into five categories: practice, people, power, pleasure, and performance. Practice, a main purpose for the children, entailed reading longer words and books, learning more words, and developing decoding skills. Reading as a social process included connections to people, both while being taught to read and when sharing texts with others. Mastery of reading provided varied feelings of power and control either over general textual ideas or over the words themselves. Pleasure and humor were emphasized in relation to children's reading, while instrumental motives were attributed to adults and to teacher-directed activities. Performance allowed for a display of knowledge and skills, but brought fear of ridicule for some. The children's rich perceptions of the reading process and of themselves as readers can guide educators as they support children in becoming strong, positive, and lasting readers. More in-depth qualitative research needs to be done on children's perceptions of reading at all levels of schooling, especially with beginning and struggling readers.     

Racing dragons and remembering aliens: Benefits of playing number and working memory games on kindergartners' numerical knowledge

Sources that contribute to variation in mathematical achievement include both numerical knowledge and general underlying cognitive processing abilities. The current study tested the benefits of tablet‐based training games that targeted each of these areas for improving the mathematical knowledge of kindergarten‐age children. We hypothesized that playing a number‐based game targeting numerical magnitude knowledge would improve children's broader numerical skills. We also hypothesized that the benefits of playing a working memory (WM) game would transfer to children's numerical knowledge given its important underlying role in mathematics achievement. Kindergarteners from diverse backgrounds (n = 148; 52% girls; M_age = 71.87 months) were randomly assigned to either play a number‐based game, a WM game, or a control game on a tablet for 10 sessions. Structural equation modeling was used to model children's learning gains in mathematics and WM across time. Overall, our results suggest that playing the number game improved kindergarten children's numerical knowledge at the latent level, and these improvements remained stable as assessed 1 month later. However, children in the WM group did not improve their numerical knowledge compared to children in the control condition. Playing both the number game and WM game improved children's WM at the latent level. Importantly, the WM group continued to improve their WM for at least a month after playing the games. The results demonstrate that computerized games that target both domain‐specific and domain‐general skills can benefit a broad range of kindergarten‐aged children.     

Les modifications du fonctionnement exécutif dans le vieillissement normal

We provide here an overview of the current state of research in the domain of executive functioning in normal aging. Normal aging has generally been associated with executive control deficits. Although impaired performance is effectively observed for the executive functions of updating, shifting, inhibition and dual-task coordination, preserved performance is also sometimes observed. We interpreted the presence of preserved performance as reflecting the integrity of some executive sub-processes or the existence of distinct functions within an executive function previously considered as unitary. Moreover, these difficulties appear also influenced by the efficiency of attentional processes (i.e., processing speed), working memory capacity and some individual genetic characteristics. Changes in the neural networks associated to executive processes were also reported. These changes consist in increased or decreased activity in task-related networks, or the recruitment of supplementary brain areas. They are considered to reflect compensatory processes or inefficient use of brain networks, when they are respectively associated to preserved or impaired task-performance.     

How do investors make predictions? Insights from analogical reasoning research

Previous work on investor decision making has focused almost exclusively on information specific to the company being judged. Consequently, every decision is viewed as a novel event, disconnected from the investor's existing knowledge. In this study, the analogical reasoning literature provides the theoretical support for arguing that investors frequently utilize existing knowledge as a basis for generating predictions about a company's future. The specific proposal is that investors transfer their existing knowledge via two different forms of analogical reasoning. The first, relational reasoning, is based primarily on structural correspondence between a novel company and an existing schema. The second, literal similarity reasoning, is based primarily on surface correspondence of a novel company and a previously encountered company. Our theoretical framework is tested in a study in which experienced investors predict the outcome of a novel company's strategy after reading about the experiences of other companies who implemented a similar strategy. The results are consistent with the occurrence of both relational and literal similarity reasoning, with relational reasoning emerging as the dominant approach to generating investors' predictions.

The contribution of logical reasoning to the learning of mathematics in primary school

It has often been claimed that children's mathematical understanding is based on their ability to reason logically, but there is no good evidence for this causal link. We tested the causal hypothesis about logic and mathematical development in two related studies. In a longitudinal study, we showed that (a) 6‐year‐old children's logical abilities and their working memory predict mathematical achievement 16 months later; and (b) logical scores continued to predict mathematical levels after controls for working memory, whereas working memory scores failed to predict the same measure after controls for differences in logical ability. In our second study, we trained a group of children in logical reasoning and found that they made more progress in mathematics than a control group who were not given this training. These studies establish a causal link between logical reasoning and mathematical learning. Much of children's mathematical knowledge is based on their understanding of its underlying logic.
