Research Findings: The study examined the development of children's social-emotional problems between 2019 (T1) and winter 2021/22 (T2) during the COVID-19 pandemic, as well as the role of children's home and preschool learning environments. The sample included 228 German children ages 3-7 years at T1 (M[subscript Age] = 5.13, SD = 0.79, 46%…

In a typical delay-of-gratification task, children have the choice between eating a small amount of treats immediately and waiting in order to receive a larger number of treats. To date, it has not been investigated whether children's time comprehension is related to the ability to wait for the larger number of treats. Time comprehension can be…

The aim of this study was to investigate sex similarities and differences in visuospatial and fluid abilities and IQ scores based on those abilities in children aged two to eight. Standardization data from the Snijders-Oomen Nonverbal Intelligence Test for Children aged 2-8 (SON-R 2-8) were used. A representative sample composed of 965 children…

Introducing kindergarten children to the engineering design process (EDP) is an important objective of early STEM education. Studies indicate that children often miss the crucial steps of testing and optimising during the EDP and do not persist in making solutions better. The present study explores how children's goal awareness, self-evaluation…

Little is known about the everyday life of very young children in refugee collective accommodation centres, hosted together with their parents. Access to high-quality provision of early education and care is not implemented. Against this background, the paper explores young children's everyday life practices in these specific centres. This paper…

From a young age, children in Western, industrialized societies overimitate others' actions. However, the underlying motivation and cultural specificity of this behavior have remained unclear. Here, 3- to 8-year-old children (N = 125) from two rural Namibian populations (Haillom and Ovambo) and one urban German population were tested in two…

Reputational concerns are known to promote cooperation. Individuals regularly act more prosocially when their behavior is observable by others. Here, we investigate 4- and 5-year-old (N = 144) children's reputational strategies in a competitive group setting. The aim of the current study was to explore whether children's sharing behavior is…

Digital technologies are increasingly present in young children's lives. How can early education systems get the best out of digitalisation while minimising its risks? This is especially urgent as the COVID-19 pandemic has accelerated our reliance on digital tools -- tools that enabled young children to continue learning when early education…

Research on teacher knowledge has been criticised for taking too narrow a view on expertise. Therefore, teacher competence frameworks have been developed that are closely related to professional demands. Their practice-oriented conceptualisations have led to innovative measures with situative demands. However, there is still a lack of knowledge on…

Human observations can only capture a portion of ongoing classroom social activity, and are not ideal for understanding how children's interactions are spatially structured. Here we demonstrate how social interaction can be investigated by modeling automated continuous measurements of children's location and movement using a commercial system…

The experience of children under age 3 with early childhood education and care (ECEC) is crucial for their learning, development and well-being and for parents' return to work. Despite increasing recognition of the importance of ECEC for the youngest children, little is known about this sector. The OECD Starting Strong Teaching and Learning…

Ownership is a cornerstone of many human societies and can be understood as a cooperative arrangement, where individuals refrain from taking each other's property. Owners can thus trust others to respect their property even in their absence. We investigated this principle in 5- to 7-year-olds (N = 152) from 4 diverse societies. Children…

Purpose: This study reports on a cross-sectional investigation of lingual coarticulation in 57 typically developing German children (4 cohorts from 3.5 to 7 years of age) as compared with 12 adults. It examines whether the organization of lingual gestures for intrasyllabic coarticulation differs as a function of age and consonantal context.…

Actions are recognized faster and with higher accuracy when they take place in their typical environments. It is unclear, however, when contextual cues from the environment become effectively exploited during childhood and whether contextual integration interacts with other factors such as children's perceptual or motor experience with an action.…

Early scientific thinking in kindergarten (6-year-olds) was investigated in a large study involving 227 participants. We investigated (1) whether individual differences across 3 scientific-thinking components (experimentation, data interpretation, and understanding the nature of science) are stable across children, (2) whether children's increased…
