The current study investigated the effects of metacognitive and executive function (EF) training on childhood EF (inhibition, working memory [WM], cognitive flexibility, and proactive/reactive control) and academic skills (reading, reasoning, and math) among children from disadvantaged backgrounds. Children (N = 134, M[subscript age] = 8.70 years)…

We investigate how the ability to respond appropriately to reasons provided in discourse develops in young children. In Study 1 (N = 58, Germany, 26 girls), 4- and 5-, but not 3-year-old children, differentiated good from bad reasons. In Study 2 (N = 131, Germany, 64 girls), 4- and 5-year-old children considered both the strength of evidence for…

In a longitudinal study (N = 54), we investigated the developmental relation between children's implicit and explicit theory of mind and executive functions. We found that implicit false belief understanding at 18 months was correlated with explicit false belief understanding at 4 to 5 years of age, with the latter being closely related to…

The Home Learning Environment (HLE) focuses on everyday learning habits in families to support the development of children's early cognitive competencies. A growing number of studies have assessed the HLE by using different conceptual approaches and various assessment methods, often focusing on either the home literacy environment or the home…

Research Findings: We assessed socio-emotional behavior, nonverbal reasoning, German receptive language, and motor skills of refugee children attending early childhood development [ECD] programs and of those who did not (N = 207, mean age = 69.4 months). Young refugee children overall demonstrated lower levels of development and more…

Differentiation hypotheses concern changes in the structural organization of cognitive abilities that depend on the level of general intelligence (ability differentiation) or age (developmental differentiation). Part 1 of this article presents a review of the literature on ability and developmental differentiation effects in children, revealing…

Little is known about how children generate options for taking action in familiar situations or how they select which action option to actually perform. In this article, we explore the interplay between option generation and selection from a developmental perspective using sports as a testbed. In a longitudinal design with four measurement waves,…

We investigated the ability to detect a face among other visual objects in a complex visual array in 3-, 4-, and 5-year-old children, as well as in adults. To this end, we used a visual search paradigm implemented on a touch-tablet device. Subjects (N = 100) saw up to eighty 3 × 3 visual search arrays and had to find and tap upon a target--a face…

The general gender discourse has currently revealed gender gaps as early as at preschool age. To analyze developmental differences between boys and girls in Mecklenburg-Western Pomerania, n = 4,251 preschoolers aged 48-83 months were examined by means of the 'Dortmund Developmental Screening for Preschools 3-6' (DESK 3-6). Using the…

First-order and advanced theory of mind (ToM and AToM), and their structures and relations were investigated in 229 children aged 5-8 years. ToM was assessed using 6 tasks from the first-order ToM scale, while AToM was measured using an 18-item battery (higher-order false-belief understanding; strange stories; faux pas test; eyes test;…

Detecting self-generated actions and imitating other-generated actions are important abilities in order to interact with others. The relationship between these domains was investigated in 6-8-month-old infants. In a contingency-preference task, infants observed their own legs on a real-time and a delayed video display. In an imitation task, the…

Children's fine motor skills (FMS) are being increasingly recognized as an important aspect of preschool development; yet, we know very little about the experiences that foster their development. We utilized a parent-administered children's fine and gross motor activities questionnaire (MAQ) to investigate links with FMS. We recruited a sample of…

The present study examines the impact of family risk factors (e.g., migration background, poverty) in early childhood on children's numeracy skills during preschool in Germany, and if these relations are mediated through the quality of the home learning environment. The data used for this research were collected using the longitudinal study…

If school closures and social-distancing experiences during the COVID-19 pandemic impeded children's skill development, they may leave a lasting legacy in human capital. To understand the pandemic's effects on school children, this paper combines a review of the emerging international literature with new evidence from German longitudinal time-use…

Do social cognition and epistemological understanding promote elementary school children's experimentation skills? To investigate this question, 402 children (ages 8, 9, and 10) in 2nd, 3rd, and 4th grades were assessed for their experimentation skills, social cognition (advanced theory of mind [AToM]), epistemological understanding (understanding…
