In this longitudinal study, we investigated the factor structure and stability of early-life temperament in a German sample, using three measures developed within Rothbart's psychobiological approach. Temperament was measured using the Infant Behavior Questionnaire Revised (IBQ-R) at the ages of 6 and 12 months, the Early Childhood Behavior…

The Big Three Perfectionism Scale (BTPS) was created to integrate different aspects of perfectionism, including the newly conceptualized concept of narcissistic perfectionism. The goal of our two studies (N = 1341) was to examine the psychometric properties of the Polish adaptation of the BTPS, supporting the validity and portability of the…

Behavioural, cognitive and emotional dysregulation related to parent borderline personality disorder (BPD) may have a major impact on parent-infant interactions. We investigated the ways in which infant social withdrawal and mother sensitivity may be associated to a BPD diagnosis in mothers. Two groups of clinic-referred mother-infant dyads were…

Personality develops during early childhood (0-3 years). As early childhood education is becoming a generalized trend worldwide, this means that school or secondary socialization overlaps with family or primary socialization during this key developmental stage. While conflict is fundamental in socialization, conflicts between peers are…

This study examined two subfactors of fundamental movement skills: locomotion skills and object-control skills. The direct and indirect effects of children's temperament on fundamental movement skills and the mediating effects of autonomy and self-regulation were examined. Participants included 278 pairs of 3- to 5-year-old children and their…

Infants attend daycare at an early age, which raises questions about children's sensitivity to the childcare environment and the role of different temperamental traits in their development in the early years. In a two-year longitudinal study with parent- and caregiver-reported data for Dutch children at the age of 1 and 2 years (120 children from…

On a daily basis, children make decisions about how to negotiate their physical environment. Sometimes they engage in physical tasks that involve risk, requiring them to judge the safety of how to negotiate the environment safely. Individual differences in children's age, sex, physical size, and personality may impact those decisions. We used…

Parenting behaviors have long been recognized as crucial to children's healthy development. However, examinations of the etiology of these behaviors are less prevalent. The current study investigated the driving forces behind parental warmth and discipline, particularly whether they are related more to traits within the parent or reactions to…

Hierarchical linear modelling was used to explore the effect of changes in maternal sensitivity on attachment over time. Child characteristics of gender, temperament, and developmental status were used as moderating factors. Data from 1,249 mothers and their children from the NICHD Study of Early Child Care and Youth Development when the children…

We investigated whether child temperament (negative emotionality, 5 months) moderated the association between maternal stimulation (5 months--2½ years) and academic readiness and achievement (vocabulary, mathematics, and reading). We applied structural equation modeling to the data from the Quebec Longitudinal Study of Child Development (N =…

Research to date has shown longitudinal changes in conscientiousness during early and middle adolescence, but most studies have been conducted in Western countries. The present study aimed to examine the pattern of mean-level conscientiousness change at the transition into early adolescence among a Chinese sample using curve of factors (CUFFS)…

Children who show elevated levels of indirect aggression (IA) from childhood to adolescence are at increased risks of experiencing detrimental outcomes. Some studies suggest that psychopathic traits could act as a predisposing vulnerability in the development of IA, but the contributions of all three dimensions of psychopathic traits in explaining…

The study explored parents' opinions regarding the forest kindergarten attended by their children. Six parents participated in the study. Semi-structured interviews were used to explore their experiences. The topics raised in the interviews concerned four areas: sources of parents' knowledge about forest kindergartens; arguments for choosing a…

Curiosity -- broadly defined as the desire to acquire new information -- enhances learning and memory in adults. In addition, interest in the information (i.e., when the information is processed) can also facilitate later memory. To date, it is not known how states of pre-information curiosity and post-information interest enhance memory in…

Children with a history of behaviorally inhibited (BI) temperament face a heightened risk for anxiety disorders and often use control strategies that are less planful. Although these relations have been observed concurrently in early childhood, middle childhood, and adolescence, few studies leverage longitudinal data to examine long-term…
