This study investigates how objective reality (truth vs falsity), intention (honest vs dishonest) and motivation (prosocial vs self-serving) affect lie labelling and moral judgment of lies. Using a comic-based task, we conducted a study with 5-6-year-olds and 9-10-year-olds (N = 194). Participants were presented with scenarios where a protagonist made either prosocial or self-serving statements that were truthful or false, with honest or deceptive intent. Results showed that younger children were more likely to judge objectively false statements as lies, while older children placed greater emphasis on the protagonist's intention. Prosocial lies were evaluated more positively than self-serving lies. However, contrary to prior research, prosocial lies were not less likely to be labeled as lies, but unlike in previous studies children were informed about the honest or dishonest intentions, which could prevent them from interpreting self-serving motivation as dishonest intentions. Additionally, lies were based on factual statements rather than opinions. Results of this research contribute to theory of mind, moral development, and social cognition research, offering insights into how children distinguish between truth and deception. The study also introduces a novel, language-independent tool for assessing children's understanding of deception, which may have applications in cross-cultural research and educational settings.

This study examined the effects of the MathByExample intervention, which integrates worked examples and self-explanation prompts into math worksheets to address 4th and 5th graders' misconceptions. Researchers conducted a year-long, classroom-based experiment in 58 U.S. classrooms, randomly assigning classrooms to experimental or control conditions. The study explored the intervention's impact on algebra readiness and the moderating effects of prior knowledge and intervention dosage. Results showed no significant overall impact of the intervention on foundational algebra knowledge (FAK) or preparation for future learning (PFL). However, further analysis provided key insights. For FAK scores, greater self-explanation prompt attempts improved learning, but only when students engaged with a high number of worksheets. Students with higher prior knowledge experienced a negative effect of attempting more worksheets, suggesting they may not benefit from excessive practice. Self-explanation attempts had a stronger positive effect for students with higher prior knowledge. For PFL scores, self-explanation attempts significantly improved PFL scores, but only for students with at least average prior knowledge, with the strongest effects seen in those completing more worksheets. These findings suggest that educators may benefit from actively incorporating the study and explanation of worked examples into elementary math instruction. To maximize their impact, teachers should regularly integrate worked examples into their lessons. Encouraging students to engage with worked examples through self-explanation may mitigate common misconceptions and enhance students' readiness for more advanced algebra concepts.

Test anxiety impacts students’ academic and psychological well-being, influenced not just by their own threat processing but also by their parents’ threat processing. This study aims to explore the association between parents’ threat processing and children’s test anxiety. The study initially recruited 53 parent–child dyads, and 45 dyads (N = 90) remained after data screening, comprising 20 children with high test anxiety (Mean age = 10.44 years) and their parents (Mean age = 38.75 years), and 25 children with low test anxiety (Mean age = 11.13 years) and their parents (Mean age = 38.36 years). All participants completed the emotional Stroop task and had their event-related potentials recorded when processing test-related and non-test-related threatening words, using the interference effects of the N2 and N450 as indicators of threat processing. Results showed that only under non-test-related threatening conditions did parents’ N2 and N450 interference effects negatively relate to children’s test anxiety levels, s suggesting that parents’ neural responses to general threat cues may play a role in shaping children’s anxiety and informing family-based interventions.

Interindividual differences related to factors like sex and family socioeconomic background in spatial ability emerge early. Embedding task-specific tracing into instruction has the potential to support early spatial abilities but must be considered relative to child characteristics and existing problem-solving strategies. Aims were to: 1) evaluate whether adding observed or observed and produced tracing to instruction improved learning of shape identification compared to spoken instruction alone; 2) determine whether performance at pretest and posttest varied as a function of child characteristics; and 3) examine how spoken and gestured problem-solving strategies changed from pretest to posttest and related to both posttest performance and condition. We also assessed the extent to which change in performance varied based upon child characteristics and problem-solving strategy use. In this study, 121 children between 44 and 72 months received brief instruction regarding triangle and rectangle shape properties. Children were divided among three conditions: 1) no tracing or gesture accompanying spoken instruction; 2) task-specific gesture observed alongside instruction; and 3) task-specific gesture observed and produced during instruction. Results indicated that children across all three conditions improved on a shape sorting task. Improvement related to age and receptive vocabulary but not condition. There were trends towards differences associated with sex as well, with girls showing a benefit associated with observing and producing gesture while boys showed equivalent performance across conditions. These findings suggest gesture is not a panacea for supporting early spatial learning. Instead, the effects of instructional cuing likely depend on child characteristics and task context.

The objective of the present study was to explore the acquisition of mathematical vocabulary by French preschoolers. Two tasks involving quantitative and spatial vocabulary (one focused on production and the other focused on comprehension) were administered to 128 children aged 3 to 6. The children came from a monolingual vs. multilingual environment and from an advantaged vs. disadvantaged socio-economic family background. The tasks were administered in the language of instruction (French language). Our results revealed an effect of the linguistic environment: children from a multilingual environment performed worse in the production of mathematical words and concepts (and especially spatial ones) than children from a monolingual environment. Furthermore, children from disadvantaged backgrounds performed worse than children from advantaged backgrounds in the comprehension and concept production tasks. Lastly, we observed an interaction between the socio-economic environment and the linguistic factor in the comprehension task. The present results might prompt new ideas and initiatives with regard to the content of educational programs.

Children at the early stage of primary school (typically aged 6–8 years) begin to encounter various stresses, including academic stress stemming from expectations and evaluations by parents, teachers, and peers. Concurrently, this age group experiences accelerated cognitive development, including the crucial capacity of inhibitory control (IC), vital for academic success. In exploring the interplay between these factors, we investigated how acute academic stress affects IC in early primary school children aged 7–8 years. Stress manipulation involved a time-constrained mathematics test with peer comparison and teacher evaluation. IC performance was assessed using the adapted Go/No-go task. Results revealed that children exposed to acute academic stress exhibited impaired IC, evidenced by a significant decrease in No-go stimulus accuracy in post-test compared to pre-test tasks. In contrast, control participants who were not subjected to stress induction but completed the same mathematical test or a simple maze test did not exhibit a similar effect. This study highlights the detrimental effects of acute academic stress on IC in young primary school children, underscoring the importance of reducing excessive academic stress to support the healthy development of children’s cognitive functions.

Purpose
Statistical learning is a mechanism that allows rapid learning without conscious effort. There is a significant gap in productive methodologies for measuring auditory linguistic statistical learning in children. Additionally, attention and working memory have been theorized to underlie this mechanism, but empirical evidence is mixed. The goal of this study was to develop an auditory linguistic statistical learning task with young children and examine the contribution of attention and working memory to outcomes on the learning task.
Method
This was a quantitative, nonexperimental study. We developed our statistical learning task through iterative rounds of piloting with children (average age 6.25 years). After, we tested 50 5- and 6-year-old native English-speaking children with typical development on our statistical learning, attention, and working memory tasks. We used generalized linear mixed models to examine the results.
Results
Thirty children (about 60 %) scored above chance on the statistical learning task, and the group average was comparable or higher than what has been reported in extant literature with similar tasks. Results of the mixed models indicated that neither attention nor working memory significantly predicted children’s outcomes on the statistical learning task.
Conclusions
The method and results provide methodological insight into measuring statistical learning abilities in young children and add to the mixed empirical evidence in the literature on the role of attention and working memory on statistical learning outcomes. Methodological and theoretical interpretations of the results are discussed.

This study explored how children (N = 196, ages 4–10) balance fairness and self-interest when making costly third-party interventions. Using a third-party trust game, children made decisions in both punishment and compensation contexts across three degrees of unfairness. Dynamic time warping (DTW) clustering was applied to identify distinct intervention patterns across unfairness conditions, offering a novel approach to capture children’s fairness behaviors as coherent trajectories rather than isolated responses. Results revealed that 4-year-olds, in low unfairness conditions (i.e., a 6:4 distribution), displayed more interventions than 10-year-olds, often exceeding what was required to restore fairness, whereas older children’s interventions were more aligned with fairness demands. In low unfairness conditions, inhibitory control was positively associated with intervention intensity, though this effect weakened with age. Age-related differences were evident in the strategies employed, particularly in punishment contexts. Younger children tended to display less clear strategies, while older children were more likely to exhibit either fairness-oriented or self-interest-oriented strategies. Negative empathy—empathy for others’ negative emotions—was positively associated with fairness-oriented decisions in punishment situations, with children exhibiting higher negative empathy more likely to be fair. However, the relationship between empathy and third-party compensation was less clear, as empathy was not significantly related to whether participants performed fairness- or self-interest-oriented behaviors. These findings suggest that with age, children’s third-party intervention strategies become more context-sensitive, shifting from spontaneous punishment in mild unfairness toward more calculated, fairness- or self-interest-oriented decisions. By contrast, third-party compensation appeared to be relatively unaffected by age in terms of orientation.

Understanding fractions is a major hurdle for many students. A key aspect of fraction comprehension is the ability to evaluate their numerical magnitude. Here, we use a number-to-line task, where students point to the location of a number on a graduated line, to characterize errors in fraction comprehension. A total of ∼ 26,000 French pupils from 6th to 10th grade were tested (U.S. equivalent grades). Error rates were high, almost 80 % in 6th grade and 45 % in 10th grade. Errors could be classified into seven dominant patterns, whose frequency varied by grade level and individual performance. Younger and lower-performing children mostly confused fractions with decimals. Older and higher-performing children often confused a fraction and its inverse . All grades also confused the roles of the numerator and the denominator. We propose a theoretical framework suggesting that errors arise as bugs in the execution of one of two main strategies: children converting the fraction into a decimal, or partitioning the line into units and counting them. This model explains the observed error patterns as stemming from inappropriate strategy selection, flawed execution, or incorrect corrective steps due to flawed execution. Our analysis provides a deeper understanding of the various traps that students face when interpreting a fraction’s magnitude, the frequency of these errors, and their sequential order.

Here, we use a number-to-line task, where students point to the location of a number on a graduated line, to characterize errors in fraction comprehension. A total of ∼ 26,000 French pupils from 6th to 10th grade were tested (U.S. equivalent grades). Error rates were high, almost 80 % in 6th grade and 45 % in 10th grade. Errors could be classified into seven dominant patterns, whose frequency varied by grade level and individual performance. Younger and lower-performing children mostly confused fractions with decimals. Older and higher-performing children often confused a fraction <span><math><mfrac><mi>a</mi><mi>b</mi></mfrac></math></span> and its inverse <span><math><mfrac><mi>b</mi><mi>a</mi></mfrac></math></span>. All grades also confused the roles of the numerator and the denominator. We propose a theoretical framework suggesting that errors arise as bugs in the execution of one of two main strategies: children converting the fraction into a decimal, or partitioning the line into units and counting them. This model explains the observed error patterns as stemming from inappropriate strategy selection, flawed execution, or incorrect corrective steps due to flawed execution. Our analysis provides a deeper understanding of the various traps that students face when interpreting a fraction’s magnitude, the frequency of these errors, and their sequential order.</div></div>","PeriodicalId":48391,"journal":{"name":"Journal of Experimental Child Psychology","volume":"263 ","pages":"Article 106373"},"PeriodicalIF":2.0,"publicationDate":"2025-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145514555","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}
