The present study examined what kind of parenting best supports toddlers' self-control in the context of poverty. Parents and toddlers (52% female; M[subscript age] = 2.60 years) in 117 families (35% White, 25% Black, 22% Latinx, 15% Multiracial, and 3% Asian; M family income = $1,845/month) engaged in structured interaction tasks, and toddlers…

Children develop and learn within dynamic contexts, yet the simplifying assumptions of common statistical methods often relegate such complexity to unexplained error. This chapter discusses ideas from the dynamic systems literature, which focuses on the interplay within and between components of complex systems, such as individuals and their…

This study evaluated whether a theory-based intervention in physical education (PE) designed to train self-control may positively impact children's quick-temperedness and disruptiveness and whether changes in executive functions (EFs) may be a correlate or antecedent of such effects. One hundred and sixteen children aged 8-9 years participated in…

Background: Both transactional and common etiological models have been proposed as explanations of why externalizing behavior problems (EBP) and internalizing behavior problems (IBP) co-occur in children. Yet little research has empirically evaluated these competing theoretical explanations. We examined whether EBP and IBP are transactionally…

Physical activity--including outdoor motor play--has been associated with learning and brain-related functions and abilities in elementary school children and adolescence. Few studies have been conducted on the relationships between active play and these cognitive processes in preschool aged children. Several investigations have revealed that…

Executive Functions (EFs) are crucial top-down processes characterized by cool and hot aspects, required for goal-directed behaviour. Only a few studies evaluated and trained concurrently cool and hot EFs. Therefore, we promote a training aiming to enhance both EFs components. A total of 91 children attending the second year of kindergarten were…

Effortful control, or the ability to suppress a dominant response to perform a subdominant response, is an early-emerging temperament trait that is linked with positive social-emotional development. Fragile X syndrome (FXS) is a single-gene disorder characterized by hallmark regulatory impairments, suggesting diminished effortful control. This…

Children with developmental delays or disabilities (DD) are at risk for self-regulation difficulties and behaviour problems compared to typically developing children. Intervening early is crucial to prevent long-term adjustment challenges across home and school contexts. Parenting has been identified as a malleable target of intervention for…

Background: Evocative gene-environment correlation (rGE) describes a process through which children's heritable characteristics influence their rearing environments. The current study examined if heritable influences on parenting and children's behavioral outcomes operate through child negative emotionality. Method: Using data from the Early…

Effective peer interaction is fundamental to social development, cognitive development, and academic success. Young children's early exposure to and development of social competence begins in the home and is further developed upon entry into early childhood programmes. In the United States, where early childhood programmes serve increasingly…

Over the past several decades, there has been a dramatic increase in research surrounding factors that influence children's school readiness, or preparedness that allows children to learn in a formal educational setting. It includes possessing early academic as well as cognitive and socio-emotional skills (e.g., self-regulation, emotion knowledge)…

Stunting has been negatively associated with children's development. We examined the range of height by testing hypotheses: (a) height is positively associated with children's development, with associations moderated by inflammation and (b) home environments characterized by nurturance and early learning opportunities is positively associated with…

Background: Preterm children have an increased risk regarding self-regulation development. Given the strong link between parenting behaviour (i.e., scaffolding and sensitivity) and children's self-regulation, parental training presents a promising way to counteract the negative consequences of preterm birth. Aims: We explored the effectiveness of…

Human beings have remarkable skills of self-control, but the evolutionary origins of these skills are unknown. Here we compare children at 3 and 6 years of age with one of humans' two nearest relatives, chimpanzees, on a battery of reactivity and self-control tasks. Three-year-old children and chimpanzees were very similar in their abilities to…

This longitudinal study investigates the differences in cognitive and socio-emotional development and academic achievement between children educated in special education classes (N = 37) and regular classes (N = 37). The study is retrospective. The first measurement point was while children were attending play-oriented kindergarten and no decision…
