Bullying is a prevalent issue in schools, and the importance of involving bystanders in bullying prevention has been recognized; however, there are few studies that examine personal characteristics that relate to the five steps of Latané and Darley's (1970) Bystander Intervention Model (notice the event, interpret as an emergency, accept…

Body mass index is a common proxy for proportion of body fat. However, body mass index may not classify youth similarly across ages and ethnicities. We used sex- and ethnic-specific receiver operating characteristic curves to determine how obesity classifications compared between body mass index and dual energy x-ray absorptiometry-based body fat…

Adults distinguish expressions of hubris from those of positive pride. To determine whether children (N = 183; 78-198 months old) make a similar distinction, we asked them to attribute emotion labels and a variety of social characteristics to dynamic expressions intended to convey hubris and positive pride. Like adults, children attributed…

The purpose of this study was to evaluate the relationship between sports experience (i.e., tennis experience) and executive function in children while controlling for physical activity and physical fitness. Sixty-eight participants (6-12 years old, 34 males and 34 females) were enrolled in regular tennis lessons (mean = 2.4 years,…

Although experiences of trauma are common, reactions vary due to a host of biopsychosocial and cultural factors that influence the individual reaction to the trauma (Nakai et al., 2015). One such factor is resiliency, the capability to adapt in adverse environmental circumstances (Basim & Cetin, 2011). This study used hierarchical multiple…

Because of the continued increase in obesity rates and decrease in children's physical activity and fitness levels, this study investigated the relationship between habitual physical activity and perceived competence, enjoyment of physical activity, and cardiorespiratory fitness among upper elementary school children. This study used the…

Children who expect they can bring about good outcomes and avoid bad outcomes tend to experience more personal successes. Little is known about factors that contribute to these "control expectancies". The purpose of the present study was to determine whether children's internal control expectancies occur in the context of parents'…

An in-depth examination of the acquisition of grammatical gender has not previously been conducted for Irish, an endangered indigenous language now typically acquired simultaneously with English, or as L2. Children acquiring Irish must contend with the opacity of the Irish gender system and the plurifunctionality of the inflections used to mark…

Research on family socialization of positive emotion has primarily focused on the infant and toddler stages of development, and relied on observations of parent-child interactions in highly structured laboratory environments. Little is known about how children's spontaneous expressions of positive emotion are maintained in the uncontrolled…

This study examined the extent to which a range of child characteristics (sex, age, socioeconomic status, reading skill and intrinsic and extrinsic reading motivation) predicted engagement (i.e., time spent) in different reading activities (fiction books, factual books, school textbooks, comics, magazines and digital texts). In total, 791 children…

The overall aim of this study was to assess the diversity of primary school children's physical activity (PA) during outdoor recess. The study was grounded in a mixed method approach, assisting in the identification of multifaceted predictors of children's PA, including insights to social behaviours during break time. Data were obtained from…

Atypical electrodermal and cardiovascular response patterns in psychopathic individuals are thought to be biological indicators of fearless and disinhibition. This study investigated the relationship between psychopathic traits and these autonomic response patterns using a countdown task in 843 children (aged 9-10 years). Heart rate (HR) and…

A number of Egyptian children experience psychiatric or mental health problems owing to a variety of internal and external qualities in their social context. These problems may mask strengths, particularly their social potential represented in their prosocial behaviour (PB). Research on emotional and behavioural difficulties (EBDs) should thus…

This study investigated the role of moral emotions in the development of children's sharing behavior (N = 244 4-, 8-, and 12-year-old children). Children's sympathy was measured with both self- and primary caregiver-reports, and participants anticipated their negatively and positively valenced moral emotions (i.e., feeling guilty, sad, or bad; and…
