Child temperament is a predictor of non-verbal ability (i.e. thinking and problem-solving skills that do not fundamentally require verbal language production and comprehension). Given that temperament scores might vary depending on whether the reporter is a parent or a teacher, this study analyses (a) whether those reports are different and (b)…

This study utilised the Early Growth and Development Study (N = 561 adoptive children; 57.2% male, 55.3% White), a study of children adopted at birth, to examine heritable (birth parent psychopathology) and prenatal risk (prenatal maternal distress and smoking during pregnancy), infant negative affectivity, adoptive parent over-reactivity and…

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…

The COVID-19 pandemic is an unexpected and major global event, with the potential to have many and varied impacts on child development. However, the implications of the pandemic for maternal depressive symptoms, early childhood temperament dimensions, and their associations, remain largely unknown. To investigate this, questionnaires were…

Most research on children's play takes a context-dependent, adult-focused observational approach to the measurement of play. The current two studies present the development and psychometric properties of the Child Self-Report Playfulness (CSRP) scale, which was presented via "puppet-show" to two samples of children. Study 1, across 98…

Temperament is important to consider when investigating factors influencing communicative development in infancy. Existing research supporting the assumption that temperament and verbal language development are interrelated covers mainly verbal development in toddlerhood onward, but few studies focus on these relations in infancy. The present…

This study examined the associations between maternal scaffolding and toddlers' active joint engagement during play and whether toddlers' temperamental activity moderates those associations. Korean mother-toddler dyads (N = 106) participated in semistructured free play. Maternal scaffolding, toddlers' joint engagement, and physical activity level…

The present longitudinal study aims at investigating the interplay between child temperament, mother-child interaction quality and child Theory of Mind (ToM) at preschool age with regard to the development of child problem behavior at school age in 115 participants. Maternal sensitivity and child temperament were assessed when children were 4…

Diverse mechanisms account for the familial aggregation of certain personality traits and externalizing psychopathology. We explored the roles of positive and negative parenting as mediators of longitudinal associations between parents' maladaptive personality traits and their children's inattention/hyperactivity problems. We collected self,…

The current study examined the associations between low-income preschool children's temperament (reactive and regulatory) and their relationships with parents and teachers. In particular, we focused on the moderating role of regulatory temperament on reactive temperament in the prediction of closeness and conflict with parents and teachers. Two…

The purpose of this research was to investigate the relationship between temperament and social cognition, including theory of mind and emotion understanding, in 34 preschool-aged children (aged 3-4 years). Theory of mind was measured with a belief-desire reasoning assessment, and emotion understanding was measured with an affective…

By 3?years of age, children generally have a firm understanding of others' reliability, but there is considerable variation among individual children. Little attention has been paid to factors that influence such individual differences. This study addressed this by assessing the relation between reliability understanding and temperament in…

Previous research indicates that children hold negative beliefs about peers with foreign accents, physical disabilities, and people who are obese. The current study examined skills associated with individual differences in children's social judgements about these typically stereotyped groups. Theory of mind, memory, and cognitive inhibition were…

Relations between having an imaginary companion (IC) and (i) descriptions of a real-life friend, (ii) theory of mind performance, and (iii) reported prosocial behaviour and behavioural difficulties were investigated in a sample of 5-year-olds (N?=?159). Children who had an IC were more likely than their peers without an IC to describe their best…
