To add or to remove? The role of working memory updating in preschool children's non-symbolic arithmetic abilities between addition and subtraction.

Early computational capacity sets the foundation for mathematical learning. Preschool children have been shown to perform both non-symbolic addition and subtraction problems. However, it is still unknown how different operations affect the representational precision of the non-symbolic arithmetic solutions.

Relations between dimensions of self-perceptions and academic achievement in Chinese children: A cross-lagged panel analysis.

The goal of the present study was to examine the associations between different dimensions of self-perceptions and academic achievement in Chinese children. Participants were 604 children in Grades 4-7 attending primary and middle schools in mainland China (342 boys, 262 girls; = 11.25 years).

Shyness, Sport Engagement, and Internalizing Problems in Chinese Children: The Moderating Role of Class Sport Participation in a Multi-Level Model.

The relations between shyness and internalizing problems have been mainly explored at the individual level, with little known about its dynamics at the group level. This study aims to examine the mediating effect of individual-level sport engagement and the moderating effect of class-level sport participation in the relations between shyness and internalizing problems. The participants were 951 children attending primary and middle school from grade 3 to grade 7 (Mage = 11 years, 509 boys) in urban areas of China.

Associations between Unsociability and Peer Problems in Chinese Children and Adolescents: A Meta-Analysis.

Research has shown that unsociability, reflected as a personal choice, is not necessarily associated with socio-emotional problems in Western countries. However, the associations between unsociability and peer problems are consistently evident in Chinese culture, yet the strength and direction in these associations are mixed. The present study aimed to examine whether unsociability is associated with peer problems and explored the potential moderators among the associations.
