Bullying in school has become a public health problem. Among the various bullying's risk factors, the vulnerabilities associated with socio-emotional skills stand out. The present study aims to explore the relationship between bullying, victimization, self-concept, and empathy; to test differences in victimization and bullying between boys and…

Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures…

We investigated performance levels on conducting continuous two-footed jumping of preschool children (4 years old) to high school students (16 years old) to clarify the developmental progression and sex differences in motor coordination and agility. In total, 450 children (boys: 227; girls: 223) participated in this study. We set 10 obstacles to…

The present study tests two predictions stemming from the hypothesis that a source of difficulty with rational numbers is interference from whole number magnitude knowledge. First, inhibitory control should be an independent predictor of fraction understanding, even after controlling for working memory. Second, if the source of interference is…

Research has shown links between emotion regulation strategies and child mental health. However, it is not well known how the characteristics of children may moderate these links. The aim of this study was to explore whether environmental sensitivity--the ability to perceive and process information about the environment--moderates links between…

Research tracking sport participation from youth to adulthood is relatively rare, as is research that tracks youth sport participation with regard to adult physical activity (PA) levels, especially in the United States. Aims of this study were: 1) To investigate the degree to which sport participation tracked across youth, adolescence, and early…

Growth in working memory capacity, the number of items kept active in mind, is thought to be an important aspect of childhood cognitive development. Here, we focused on participants' awareness of the contents of their working memory, or "meta-working memory," which seems important because people can put cognitive abilities to best use…

Despite the high prevalence of and documented impairment associated with pediatric anxiety disorders, less than half of youth access mental health services. This study examined (a) the utilization of eight school services and supports (e.g., seen a school counselor for a mental health reason, placement in a special class for a behavior or…

This study explored the profiles of Longitudinal Life Environmental Satisfaction (LLES) during the COVID-19 pandemic, evaluating their predicting role in social-emotional adjustment in children and early adolescents. 488 children (M[subscript age] = 8.54; SD = 0.63), and 129 early adolescents (M[subscript]age = 11.08, SD = 0.48) completed two…

Tenets of the Boivin et al. (1995) social process model were reexamined with two longitudinal samples using both the original and contemporary analytic strategies. Study goals included reconstructing (e.g., quasireplicating) Boivin et al.'s (1995) original findings and evaluating hypothesized relations across both comparable and longer…

Children's work habits at school include being a hard worker, turning in work on time, following classroom rules, and putting forward one's best effort. Models on youth character, noncognitive skills, and social-emotional learning suggest that self-management skills like work habits are critical for individuals' subsequent academic success. Using…

The current study examined the role of family orientations on the achievement motivations (i.e., achievement goal orientations and intrinsic motivation) of high school youths of different generational status (i.e., from immigrant or non-immigrant families) when their perception of their parents' goals and classroom goal structures were tested…

Regulatory focus may shape the manner in which students perceive and respond to learning environments and then further influence their attitudes and behaviors. In the current study, 1487 adolescents in China were surveyed to illuminate the relationship between regulatory focus and learning engagement. The results showed that promotion focus was a…

This 2-year prospective study aimed to examine the predictive role of students' achievement goals (mastery-approach and performance-avoidance) on socioemotional adjustment in high school by assessing the potential mediating contribution of academic motivations. A total of 407 high school students (46% boys) were surveyed each year in Secondary 2…

Mathematical giftedness (MG) is an intriguing phenomenon, the nature of which has yet to be sufficiently explored. This study goes a step further in understanding how MG is related to expertise in mathematics (EM) and general giftedness (G). Cognitive testing was conducted among 197 high school students with different levels of G and of EM. Based…
