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…

Learning academic vocabulary is a crucial task for all students, but especially challenging for students with speech, language, and communication needs (SLCN) and those who are multilingual. Following a participatory research strategy, we analyze whether iconic gestures can be integrated in teaching routines in an inclusive elementary school and…

This study investigated the vocabulary development of children (N = 547) from linguistically and socioeconomically diverse classrooms in Germany from age 3 in preschool to age 7 in Grade 1. The results showed that for dual language learners (DLLs, n = 107) growth rates in their German majority language skills varied over classrooms. Compared to…

The association between academic self-concept and achievement is assumed to be reciprocal. Typically, the association is analyzed by variants of the classical cross-lagged panel model. Results with more recently developed methodological approaches, for example, the random intercept cross-lagged panel model, its continuous-time implementation, and…

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…

The concept of "Home Learning Environment" (HLE) covers activities in a family providing intellectual stimulation for a child, such as reading to him or her or visiting libraries. Numerous studies have shown an association between HLE and children's cognitive development. In this longitudinal study, we focus on HLE as a predictor for…

New experiences, challenges, and opportunities inherent in biographical transitions are expected to foster the psychosocial development of individuals. Our study investigated, first, developmental gains in children's language competence, social support seeking, and self control following the transitions to kindergarten and school; second, whether…

Although J. Piaget (1968) assumed that children up to 7 years old are unable to consider more than 1 stimulus dimension in their judgments, subsequent research has demonstrated that preschoolers can consider 2 dimensions, such as the width and length of rectangles to estimate their area (F. Wilkening, 1979). The present study addressed the…
