A foundational mechanism underlying human cooperation is reciprocity. In the context of repeated interactions with others, it is not always clear the degree to which in-kind responses reflect responsiveness to partners' prior behaviors ("reactive" responses), an interest unrelated to the partner ("nonreactive" responses), or…

At what ages are young people most open to political influence? We test the "formative years" model that underscores the importance of childhood experiences for political development against the "impressionable years" model that asserts the primacy of lessons learned during adolescence. To assess the relative merits of these…

Children's positive perceived motor competence (PMC) provides motivation for physical activity. Theoretically young children (<8 years) have inflated PMC but as children cognitively develop, perceptions are hypothesized to decrease. This study investigated strength of PMC association over time, whether any change was negative (i.e. PMC…

The early educational support of basic school skills during nursery can have a positive impact on a successful transition into primary school and future school success and achievement -- especially for in this context low-performing children. Therefore, most German nurseries developed additional concepts to support the acquisition of basic school…

Purpose: The aim of this longitudinal study was to describe developmental courses of childhood dysarthria against the background of typical speech motor development by collecting auditory-perceptual data. Method: Fourteen children (four girls, 10 boys; 5;1-8;4 [years;months] at Time 1) with neurological conditions (CNC) and 14 typically developing…

Though it is well-established that self-esteem develops from childhood well into old age, little is known about the processes that influence this change, especially among young populations. This international, cross-sequential study examined the development of self-esteem in 1599 second-graders (Age M[subscript T1] = 7.99, SD[subscript T1] = 0.52…

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…

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 this commentary, Ahnert addresses the Beckh and Becker-Stoll's (2016) paper that characterized positive teacher-child relationships through high levels of closeness and low levels of conflict. Once teacher-child relationships are positively established, the children benefit the most in developmental domains which are considered typically weak…

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…

The aim of this article is to demonstrate how relational experiences with parents and preschool teachers provide children with a feeling of security that facilitates the development of competence in different domains. We first focus on the mechanisms regarding how secure attachments to parents serve as an important foundation for later…

In a 19-year longitudinal study, the 15% most inhibited and the 15% most aggressive children at ages 4-6 years were followed up until age 23 years and were compared with controls who were below average in preschool inhibition or aggressiveness. As adults, inhibited boys and girls were judged as inhibited by their parents and showed a delay in…

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…

Responding to disruptive or troubled pupils with emotional and behavioural difficulties (EBD) remains a highly topical issue. The challenges these children present relate to wider issues of continuing political concern: the perceived declining discipline in schools; school and social exclusion; the limits to inclusion for children with special…

When Canadian parents look back on their own lives and the lives of their parents, they see changes across a generation that have profoundly affected their parenting experience, compared to when they themselves were young children. Supports for today's parents must take into consideration these changes that affect the care and nurturing of…
