The purpose of the current study was to extensively investigate not only bystander roles but also individual bystanders’ moral emotional responses in the context of cyberbullying based on the perpetrator's perceived popularity and the message type. Data from 566 adolescents in grade 7 attending six middle schools in South Korea were used to identify their bystander behavior and moral emotions in response to vignettes about cyber scenarios. Using latent profile analysis, the current study identified five types of bystanders: limited bystanders, pro-bullies, outsiders, defenders, and inconsistent bystanders. Moreover, multinomial logistic regressions were performed to determine the predictive power of the moral emotions of each bystander type. The findings indicated the importance of understanding bystanders’ roles for designing effective intervention strategies regarding moral emotions, leading to adolescents’ improved moral sensitivity.

This study examined two subfactors of fundamental movement skills: locomotion skills and object-control skills. The direct and indirect effects of children’s temperament on fundamental movement skills and the mediating effects of autonomy and self-regulation were examined. Participants included 278 pairs of 3- to 5-year-old children and their mothers from 4 day care centres. High levels of emotionality and sociability were positively associated with a high level of children’s autonomy, self-regulation and fundamental movement skills. There was a mediating effect of children’s autonomy and self-regulation on the effect of temperament on locomotion skills, but there was no mediating effect on object-control skills. The results provide empirical evidence of holistic development by confirming that temperament is a variable that affects gross motor development and that children’s psychological development is related to motor development.

Given the increasing importance of early childhood teachers, this study aims to identify whether past maternal parenting is related to burnout through the double mediation of teacher self-compassion and teacher efficacy, using model comparison. To this end, a survey was conducted with 329 early childhood teachers in Korea. The positive maternal parenting perceived by teachers was negatively related to burnout through teachers’ self-compassion and efficacy. Positive maternal parenting reduced burnout by increasing self-compassion and consequently teacher efficacy. Teachers’ self-compassion was more closely related to burnout than teacher efficacy, which was treated as an important variable in relation to teachers. These results suggest that early childhood teachers’ self-compassion is a significant variable in relation to burnout and suggestions are provided for specific support programs to promote teacher self-compassion.

This study was conducted to identify the relation between children’s autonomy and motor development mediated by teacher–child relationships. Are there differences between teacher–child relationships and motor development according to the gender of the child? To answer this question, the fundamental movement skills of 292 children were measured, and teacher–child relationship and children’s autonomy data were collected from the teachers. There was a gender difference in locomotion skills; however, there was no difference in object control skills. In the case of girls, a conflict teacher–child relationship mediates the association between autonomy and object control skills. This study highlights the importance of teacher–child relationships, which are mainly discussed in relation to conventional social-emotional development, and provides examples of whole-child development.
