The ability to categorize concepts is an essential capability for human thinking and action. On the one hand, the investigation of such abilities is the purview of psychology; on the other hand, subject-specific educational research is also of interest, as a number of research works in the field of science education show. For computer science…

This study expanded on research on temporal relations among motivation constructs as stated by expectancy-value theory, which has so far neglected the differentiation of value facets, the examination of long time spans with multiple measurement waves, and domain-specific patterns of findings. We examined the longitudinal relations among academic…

Creativity is a broad and complex construct, difficult to define and to quantify, assumed to introduce new impulses into science education (STEM), and leading to better acceptance of science by adolescents. Therefore, increasing efforts are being undertaken to integrate traditional creativity (Arts), in modifying STEM to STEAM. Consequently, a…

Principals (policy makers) have debated the progress in U.S. student performance for a half century or more. Informing these conversations, survey agents have administered seven million psychometrically linked tests in math and reading in 160 waves to national probability samples of selected cohorts born between 1954 and 2007. This study is the…

Loneliness is a stressful experience that appears to interfere with health and social integration (SI). Recently, researchers proposed that both antecedents and consequences of loneliness may change across the life span. To fully understand the processes related to loneliness it may thus be crucial to adopt an age-differentiated perspective. This…

In a cross-sectional questionnaire study with N = 1658 German students, aged between 12 and 17 years (M = 14.1, SD = 0.5), we investigated the relation of students' personal belief in a just world (BJW) to their school absenteeism and functions of school refusal behavior. In accordance with recent studies which identified negative relations…

Numeracy and literacy skills have become increasingly important in modern labour markets. The large gender differences that several studies have identified have therefore sparked considerable attention among researchers and policy makers. Little is known about the moment in which such gaps emerge, how they evolve and if their evolution differs…

Purpose: From a psycholinguistic perspective, the quality of the stored word form in the phonological input lexicon, as well as its effective retrieval from the phonological output lexicon, is of great importance in lexical processing. This study aimed at gaining a deeper understanding of (a)typical word form processing in primary school children.…

Purpose: In youth, cross-sectional studies reported age differences in balance performance that were in favor of adolescents. Thus, trainability of balance performance might be different in children compared to adolescents. The purpose of this study was therefore to compare the effects of balance training (BT) on balance performance between…

Following recommendations by the European Commission, bilingualism has been promoted in various ways in the German federal state of Baden-Württemberg. Language classes and the concept of immersion were gradually introduced in primary schools, while, at the secondary level, Content and Language Integrated Learning (CLIL) programmes were…

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…

By differentiating between five specific forms of cybervictimization (denigration, betrayal, social exclusion, cyberstalking, happy slapping), the present study examined the multifaceted structure of cybervictimization and specific relationships of these five forms of cybervictimization with students' self-esteem and social relationships.…

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…

In Sweden and in Germany, an extensive system of extended education programmes and activities has been established within the last decades. Prototypic examples of this development are school-age educare centres in Sweden and all-day schools in Germany. In this article a bi-national comparison, aiming to find some similarities and differences by…

Background: German participles are formed by a co-occurrence of prefixation and suffixation. While the acquisition of regular and irregular suffixation has been investigated exhaustively, it is still unclear how German children master the prosodically determined prefixation rule (prefix "ge-"). Findings reported in the literature are…
