The present study followed a sample of first-grade (N = 316, M[subscript age] = 7.05 at first test) through fourth-grade students to evaluate dynamic developmental relations between vocabulary knowledge and reading comprehension. Using latent change score modeling, competing models were fit to the repeated measurements of vocabulary knowledge and…

The development of scientific thinking was assessed in 1,581 second, third, and fourth graders (8-, 9-, 10-year-olds) based on a conceptual model that posits developmental progression from naïve to more advanced conceptions. Using a 66-item scale, five components of scientific thinking were addressed, including experimental design, data…

This study examined how peer relationships (i.e., sociometric and perceived popularity) and teacher--child relationships (i.e., support and conflict) impact one another throughout late childhood. The sample included 586 children (46% boys), followed annually from Grades 4 to 6 (Mage.wave1 = 9.26 years). Autoregressive cross-lagged modeling was…

Data from 1,364 children and families who participated in the National Institute of Child Health and Human Development's Study of Early Child Care and Youth Development were analyzed to track the early correlates and later academic outcomes of planning during middle childhood. Maternal education, through its effect on parenting quality when…

The pervasive income-achievement gap has been attributed in part to deficiencies in executive functioning (EF). The development of EF is related to children's planning ability, an aspect of development that has received little attention. Longitudinal data from the National Institute of Child Health and Human Development study of early child…

Recent studies have shown that the metacognitive judgments adults infer from their experiences of encoding effort vary in accordance with their naive theories of intelligence. To determine whether this finding extends to elementary schoolchildren, a study was conducted in which 27 third graders (M[subscript age] = 8.27) and 24 fifth graders…

This study examined the developmental trajectories of maladaptive perfectionism over a 7-year period among African American youth living in an urban setting (N = 547). In particular, the study attempted to determine whether two maladaptive aspects of perfectionism (socially prescribed and self-critical) changed over time and could be distinguished…

Children and adolescents evaluated group inclusion and exclusion in the context of generic and group-specific norms involving morality and social conventions. Participants ("N" = 381), aged 9.5 and 13.5 years, judged an in-group member's decision to deviate from the norms of the group, whom to include, and whether their personal preference was the…

This study aims to investigate the effects of a training programme in creativity on developing creative abilities among 9-10-year-old children with visual impairment in Jordan. The study sample consisted of 41 students from fourth and fifth grades, who were randomly selected and divided into two experimental groups and two control groups. To…

Family interviews were conducted with 28 7-12-year-old children who had experienced various forms of bullying and relational aggression by their peers, as well as with their parent and with an older sibling. Interviews explored possible supportive strategies of older siblings, parents, and teachers. All bullied children reported negative feelings…

The combination of changes occurring at the transition to middle school may be a catalyst for the onset of depressive symptoms, yet teacher support at this transition is protective. Research points to certain temperamental traits as risk factors for developing depressive symptoms. This study examines student reports of teacher support and teacher…

A dependent group contingency strategy called Fair Play Game was applied to promote increase in number of steps during physical education classes for sixth-grade students. Results from a multiple baseline design across three classes showed that the mean number of steps for baseline vs. intervention were: Class 1: 43 vs. 64 steps/minute; Class 2:…

Changes in family structures, such as the increase in the number of cohabiting couples, divorces, and blended families pose new challenges for fatherhood and research on fatherhood has been mainly adult-centred. This research studied how Finnish children perceive good fatherhood and what expectations they set for fathers. The following research…

This study investigated how parental beliefs about children's emotions and parental stress relate to children's feelings of security in the parent-child relationship. Models predicting direct effects of parental beliefs and parental stress, and moderating effects of parental stress on the relationship between parental beliefs and children's…

Previous studies of childhood fear, worry, and ritualistic behaviour have been limited by restricted age ranges, narrow ranges of anxiety phenomena, non-comparable methodologies, and assessment of typical behaviour within a pathological context. Content and intensity of fear, worry, and ritualistic behaviour, and associations among these…
