During preschool age, three precursors to self-regulated learning (SRL) can be identified: general self-regulation ability, speech competence, and executive functioning. There is evidence for a large interindividual heterogeneity in these precursors which may have an impact on the development of SRL. This study (a) examined heterogeneity in SRL…

Notwithstanding their relevance to children's cognitive development, home literacy activities of preschool children with migration backgrounds have only been partly explored. Therefore, the current understanding of this topic, particularly in a German setting remains incomplete. This study aimed to evaluate the differences between preschool…

Children in early childhood education and care (ECEC) spend a considerable amount of time interacting with their peers. However, open questions remain on whether and how children influence their peers' language development. The present study examined effects of peers' German receptive vocabulary (n = 1,871) on individual children's (n = 431)…

First-order theory of mind (ToM) development has shown to conform to a Guttman scale, with desire reasoning developing before belief reasoning. There have been attempts to test for internal consistency and scalability in advanced ToM, but not over a broad age range and only with a limited set of tasks. This 2-year longitudinal study (N = 155;…

Can early childhood education (ECE) support the societal language development of children from linguistically diverse backgrounds? This study examined how existing variation in classroom interaction quality (CLASS Pre-K), classroom composition (percentages of children from low-income backgrounds and dual language learners [DLLs]), and duration of…

Based on longitudinal data (n = 338) from the German National Educational Panel Study (NEPS) competence development (mathematics and language) of three groups with different mathematical preconditions (+/- 1 SD) were compared between age 4 to 10. Groups were composed by first measurement of mathematical achievement in pre-school age (5/6 years).…

This paper focuses on the influence of socio-economic risk factors and different aspects of the home learning environment in early childhood on children's language competencies (vocabulary and grammar skills). The assumption is that children with more risk factors have lower competencies, but the home learning environment (measured by everyday…

Cooperation between preschools and parents is one key dimension of pedagogical quality in early childhood education and care (ECEC). We examined the structural characteristics of ECEC that predict preschool cooperation activities and how they are associated with children's language and social-emotional skills at the age of 3. The results are based…

Acquisitionists generally assume a relation between code-mixing in young bilingual and trilingual children and language dominance. In our cross-sectional study we investigated the possible relation between code-mixing and language dominance in 122 children raised in Spain or Germany. They were bilingual, trilingual or multilingual, the latter…

Shared-book reading is a well-established intervention to foster vocabulary development. Factors influencing its effectiveness are, however, less well studied, particularly with regard to story-delivery. We contrasted a read-aloud with a free storytelling approach and tested effects on vocabulary learning. In the first study, 83 preschoolers aged…

Theories and research in embodied cognition postulate that cognition grounded in action enjoys a processing advantage. Extending this theory to the study of how fine motor skills (FMS) link to vocabulary development in preschool children, the authors investigated FMS and vocabulary in 76 preschoolers. Building on previous research, they…

This study examined longitudinal relations between early measures of prosocial action in infancy as well as cognitive and social-cognitive abilities, and the sharing behaviour of preschool children. The results reveal relations between delay-of-gratification at 24 months and inhibitory control at 30 months, and children's sharing at 5 years.…

This study investigated the longitudinal relation between children's theory of mind and their metacognitive knowledge with a special focus on the impact of language on this relation. Measures of theory-of-mind understanding and metamemory knowledge were assessed in 133 3-year-old children at 4 measurement points separated by half-year intervals.…

The present paper was written under the auspices of the interdisciplinary research group "Educational Processes, Competence Development, and Selection Decisions at Preschool and Primary School Age (BiKS)" (FOR 543), funded by the German Research Foundation (DFG). The surveys were conceptualised and supervised as part of the developmental…

This paper investigates the association between obesity and skill attainment in early childhood (aged 2-4 years). Data from the German Socio-Economic Panel Study are used to estimate models of developmental functioning in four critical areas (verbal skills, activities of daily living, motor skills, and social skills) as a function of various…
