Many metropolitan cities have undergone rapid demographic changes in recent years, and such changes hasten and widen linguistic diversities. Similar changes are happening in Sydney, Australia and Hamburg, Germany. These changes are most acutely felt and observed in the classrooms where multiple languages are spoken, despite a prevalent monolingual…

Background: Recent research has shown that socio-emotional and language competencies are positively associated with each other. However, few studies have explored these associations for the second language competencies (L2) of young dual language learners (DLLs). Aims: This longitudinal study investigated possible bidirectional associations…

The Home Learning Environment (HLE) focuses on everyday learning habits in families to support children's competency development. In this study, we used multitrait-multimethod (MTMM) analyses to compare two theoretical dimensions and three methods for assessing the HLE and their associations with linguistic and mathematical competencies of…

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…

Lexical development of bilingual children is influenced by a number of input factors. In the present study, early lexical skills of 25-month old children growing up with Turkish and German were assessed. Parents of 92 children filled out a newly developed list for productive Turkish vocabulary, as well as a vocabulary list for German. A parental…

Several studies have revealed the cognitive and linguistic benefits of balanced bilingualism, but the research on balanced biliteracy is still in its initial stages (Marinis et al. submitted. "Biliteracy Education Impacts on Cognition Selectively"). This study investigates the positive effects of balanced biliteracy on the development of…

Quantity recognition in whole number representations is a fundamental skill children need to acquire in their mathematical development. Despite the observed correlation to mathematics achievement, however, the ability to recognize quantities in structured whole number representations has not been studied extensively. In this article, we…

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;…

After a theoretical overview of the concept of heritage language (HL) from a plurilingual perspective, we will describe the project "Images on the (teaching of) Portuguese Language abroad". For this project, several drawings were collected, produced by lusodescendant children living in Germany and attending supplementary Portuguese…

Research Findings: In order to examine the explanatory power of behavioral self-regulation in the domain of emotion knowledge, especially in a non-U.S. culture, 365 German 4- and 5-year-olds were individually tested on these constructs. Path analyses revealed that children's behavioral self-regulation explained their emotion knowledge in the…

Phonological awareness, rapid automatized naming (RAN), letter knowledge, and oral language are all significant predictors of successful literacy acquisition in several languages. However, their relative importance is less clear and depends on language characteristics, the specific aspect of literacy assessed, and the phase of literacy…

Research Findings: This study investigated the long-term interrelations among children's language competencies, their home literacy environment (HLE), and 3 aspects of socioemotional development from ages 3 to 8, controlling for characteristics of the child and family. For this sample of 547 typically developing German children, parents and…

Academic self-concept has been conceptualized as a multidimensional and hierarchical construct. Previous research has mostly focused on its multidimensionality, distinguishing between verbal and mathematical self-concept domains, and only a few studies have examined the factorial structure within specific self-concept domains. The present study…

The influence of English on German has been an ongoing subject of intense popular and academic interest in the German sphere. In order to better understand this language contact situation, this research project investigates anglicisms--instances of English language material in a German language context--in the German hip hop community, where the…

In developed countries, obesity tends to be associated with worse labor market outcomes. One possible reason is that obesity leads to less human capital formation early in life. This paper investigates the association between obesity and the developmental functioning of children at younger ages (2-4 years) than ever previously examined. Data from…
