Young children tend to behave more generously when their actions are identified than when they are anonymous, yet we know little about the cognitive foundations required for anonymity to impact generosity. In three studies we examined Canadian children's understanding of anonymity and its impact on sharing in anonymous and identified contexts.…

This research explored early ecological-moral sense, by investigating 2.5- and 5-year-old children's evaluations of overt and covert pro-environmental actions using both rewarding and reaching paradigms (N = 96; 100% White). In Experiment 1, the overt pro-environmental action was compared with the action of harming the environment. In Experiment…

The purpose of this systematic review was to examine the influence of relative age effect (RAE) on motor competences (MC) and physical fitness (PF) of preschool children. The search was conducted through three different databases: Web of Science, Scopus and EBSCO up to 11 August 2023. This study was conducted and reported according to the PRISMA…

Purpose: Our goal was to compare statistical learning abilities between preschoolers with developmental language disorder (DLD) and peers with typical development (TD) by assessing their learning of two artificial grammars. Method: Four- and 5-year-olds with and without DLD were compared on their statistical learning ability using two artificial…

Learning requires effort, but children cannot try hard at everything. Here, we evaluated whether children use their improvement over time to decide whether to stick with a challenge. To eliminate the effect of individual differences in ability or prior knowledge, we created a novel paradigm that allowed us to surreptitiously control children's…

This study investigated the development of divergent thinking (DT) in early childhood. We followed 107 4-year-olds for 1.5 years. Children's DT was assessed with the Alternative Uses Task (AUT) every 6 months, four times in total. Within the AUT, children were asked to generate unusual uses of common objects while explaining how they came up with…

The number line estimation task is frequently used to measure children's numerical magnitude understanding. It is unclear whether the resulting straight, horizontal, left-to-right-oriented estimate patterns indicate task constraints or children's intuitive number--space mapping. Three- to six-year-old children (N = 72, M[subscript age] = 4.89, 56%…

The current study examined to what extent face and speech processing interact with each other and whether they enhance or impair the processing of the other in 5-year-olds (n = 51) and adults (n = 34). Using a computer-based speeded sorting task allowed to directly test the influence of auditory speech on face processing and the influence of face…

This study aims to examine emotion recognition and false belief performances of 4-5-year-old (48-71 months) deaf or hard-of-hearing (DHH) children. The performances have been assessed using the Turkish Version of the Theory of Mind Task Battery for Children. The DHH children have been continuing schooling in inclusive settings with an…

Previous research demonstrates that children delineate more nuanced color boundaries with increased exposure to their native language. As socioeconomic status (SES) is known to correlate with differences in the amount of language input children receive, this study attempts to extend previous research by asking how both age (age 3 vs 5) and SES…

Young children can generalize from known to novel, but the underlying mechanism is still debated. Some argue that from an early age generalization is category-based and undergoes little development, while others believe that early generalization is similarity-based, and the use of categories emerges over time. The current research brings new…

Across the early childhood period of development, young children exhibit considerable growth in their executive functioning (EF) and vocabulary abilities. Understanding the developmental trajectory of these seemingly interrelated processes is important as both early vocabulary and EF have been shown to predict critical academic and socio-emotional…

Learning environments can support the development of foundational knowledge and promote children's attitudes toward learning and school. This study explores the relation between school enjoyment and general knowledge from preschool (2016-2017) to kindergarten (2017-2018) in 1359 children (M[subscript age] = 55, 61 months, female = 50%; 58.5%…

Research Findings: Emotion knowledge is one facet of social and emotional learning (SEL) that emerges in early childhood. Various interventions and measures target preschoolers' emotional skills to bolster these foundational competencies prior to formal schooling. One measure of emotion knowledge specifically with preschool children is the Affect…
