The architecture of sleep undergoes distinct changes during childhood and early adolescence. Slow wave sleep is involved in memory processing and may support active consolidation of newly encoded representations to support the formation of abstracted "gist" memories. Here, we examined sleep and overnight memory formation in German school…

The psychological mechanisms that subserve inductions about novel social categories in childhood are hotly debated. While research demonstrated that language, and in particular generic statements, plays a major role in how children learn to attribute properties to social categories, developmental theories propose other mechanisms. One theoretical…

Curriculum research is an important tool for understanding complex processes within a degree program. In particular, stochastic graphical models and simulations on related curriculum graphs have been used to make predictions about dropout rates, grades, and degree completion time. There exists, however, little research on changes in the curriculum…

The influence of the epistemological beliefs of parents on the development of comprehensive scientific reasoning abilities was investigated in a five-wave longitudinal study from kindergarten to elementary school. The 161 German 5-10-year-olds (89 girls, 72 boys) were assessed yearly on their scientific reasoning abilities using comprehensive…

Experiencing the moral emotions of gratitude and moral elevation are responses to witnessing virtuous deeds of others. Both emotions have been found to share similar features and behavioral consequences, including the stimulation of personal development. The broaden-and-build theory of positive emotions indicates that gratitude and elevation…

Writing, as a highly complex strategic literacy skill alongside reading, is an essential prerequisite for learning and determines a student's educational success. In diverse contexts, a student's linguistic repertoire may involve multiple languages, which may serve as mutual resources in his or her multilingual writing skill development. Drawing…

Academic performance (i.e., grade point average) determines career entry factors as well as career success and is thus crucial for students' future careers. Besides individual factors such as personality traits, individuals' social embeddedness has been shown to enhance performance. Regarding academic performance, relationships to fellow students…

Views on aging have been shown to predict the occurrence of events related to physical health in previous studies. Extending these findings, we investigated the relation between aging-related future self-views and life events in a longitudinal study across a range of different life domains. Participants (N = 593, age range 30-80 years at…

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…

The world of work is being impacted by a fourth industrial revolution, transformed by artificial intelligence and other emerging technologies. With forecasts suggesting large shares of workers, displaced by automation, in need of upskilling/reskilling, the design of active skills policies is necessary. Conventional methods used to anticipate…

We examined independent and interactive links among three central characteristics of children's experiences in early childhood education and care and the German receptive vocabulary of single language learners and dual language learners (DLLs). We allowed for possible differential effects depending on children's language background. Our sample…

Current higher education is characterized by a proliferation of distance education programs and by an increasing inclusion of nontraditional students. In this study we investigated whether and to what extent nontraditional students are particularly at risk for attrition (vs. graduating) from distance education programs. We conducted a secondary…

Establishing local coherence relations is central to text comprehension. Positive-causal coherence relations link a cause and its consequence, whereas negative-causal coherence relations add a contrastive meaning (negation) to the causal link. According to the cumulative cognitive complexity approach, negative-causal coherence relations are…

After consistently bad results in every PISA test (Programme for International Student Assessment) and an accompanying prediction of lack of skills in its future workforce, Germany might be on track for losing out in international competition. Because of PISA's overwhelming marketing presence, its results are a major political influence. The OECD…

Executive functions (EFs) may help children to regulate their food-intake in an "obesogenic" environment, where energy-dense food is easily available. There is mounting evidence that overweight is associated with diminished hot and cool EFs, and several longitudinal studies found evidence for a predictive effect of hot EFs on children's…
