Prior studies were limited in the comparison of false belief tasks with desire tasks due to lack of consideration of level of executive functions. To compensate for this, executive functions were included in new preference-related and game-related tasks of conflicting desire. These tasks were administered to 246 preschoolers ranging from 2.5 to 4 years of age. Statistical analysis was by one-way ANOVA and repeated measures ANOVA. Results showed significant main effects depending on age and task type. Younger children lacked ability of executive function, such as inhibition and working memory. Older preschoolers averaged better scores on task performance, showing that it is difficult for younger children to control their own desires and select the contradicted view.

Executive safety leadership is essential to prevent accidents in the workplace. However, will safety be secured by emphasizing only executive safety leadership to workers? In this study, the impact of executive safety leadership on the workplace hazard level was analyzed by adding the supervisor's safety role as a mediating variable. This paper shows that executive safety leadership has no direct effect on workplace hazard levels. However, executive safety leadership was found to have a significant impact on the supervisor safety role, and the supervisor safety role was found to lower the hazard levels in the workplace. In summary, executive safety leadership was found to reduce the hazard levels in the workplace through the full mediating effect of the supervisor safety role. Based on these research results, this study seeks to present the following recommendations to the government and management: The government should ensure that a workplace safety and health system is established by strengthening the effects of other mediating factors, such as strengthening the role of supervisors who are actually responsible for workplace safety and health. Executives must grant supervisors actual authority and responsibility to properly perform their safety roles and establish personnel and performance evaluation systems.

Household chaos, represented by high levels of disorganization and instability in the home, has been linked with suboptimal outcomes for preschoolers. The aim of this study was to examine the roles that sleep problems and executive function play in the association between household chaos and preschoolers' aggression and prosocial behavior. The sample for the study consisted of 420 preschoolers and their mothers. The mothers provided reports on the level of chaos in the home and their preschoolers' sleep problems, executive function, and social behavior, including aggression and prosocial behavior. The data was analyzed using structural equation modeling. When preschoolers' sleep problems and executive function were included in the model as mediators, the results indicated that household chaos did not have direct effects on preschoolers' aggression and prosocial behavior. Such effects were instead serially mediated by preschoolers' sleep problems and executive function, respectively. The higher the degree of household chaos, the more preschoolers displayed sleep problems and deficits in executive function, resulting in more aggression and less prosocial behavior. The findings from this study emphasize the significance of reducing household chaos in order to reduce preschoolers' aggression and promote prosocial behavior. They also underscore the need to identify additional variables that mediate the impact of household chaos on preschoolers' social outcomes.

Background and objective: This study identifies whether children's planning-organizing executive function can be significantly classified and predicted by home environment quality and wealth factors. Methods: For empirical analysis, we used the data collected from the 10th Panel Study on Korean Children in 2017. Using machine learning tools such as support vector machine (SVM) and random forest (RF), we evaluated the accuracy of the model in which home environment factors classify and predict children's planning-organizing executive functions, and extract the relative importance of variables that determine these executive functions by income group. Results: First, SVM analysis shows that home environment quality and wealth factors show high accuracy in classification and prediction in all three groups. Second, RF analysis shows that estate had the highest predictive power in the high-income group, followed by income, asset, learning, reinforcement, and emotional environment. In the middle-income group, emotional environment showed the highest score, followed by estate, asset, reinforcement, and income. In the low-income group, estate showed the highest score, followed by income, asset, learning, reinforcement, and emotional environment. Conclusion: This study confirmed that home environment quality and wealth factors are significant factors in predicting children's planning-organizing executive functions.

Higher cognitive functions refer to the highest level of human intellectual functioning, including concept formation, reasoning, and executive functions. The executive functions can be conceptualized as having four components : volition, planning, purposive action, and effective performance. Because higher cognitive functions represent the most advanced stages of intellectual development, they are often highly susceptible to the effects of brain injuries and mental disorders. The ability to perform effectively within the environment is determined in large part by an individual's adequacy in performing such higher-order functions. Especially executive functions are necessary for appropriate, socially responsible, and effectively self-serving adult conduct. Threfore, an assessment of the psychiatric patient's performance in these areas will provide useful diagnostic information, as well as information concerning social and vocational prognosis.

This study examined the dual mediating effects of preschoolers' executive function and counterfactual thinking in the relationship between maternal reflective functioning and preschoolers' higher-order thinking. Participants included 293 preschoolers and their mothers in Daegu city and Gyeongsang province. The mothers completed questionnaires regarding their reflective functioning, preschoolers' executive function, and creative thinking. Teachers completed questionnaires regarding preschoolers' critical thinking and caring thinking. Preschoolers' counterfactual thinking was measured by interviews. Data were analyzed using descriptive statistics and Pearson correlation analysis with SPSS 25.0. Path analysis and bootstrapping were used with AMOS 25.0 program. Also, specific indirect effect were analyzed using AMOS user-defined estimand function. The primary results of this study are as follows. Maternal reflective functioning had an indirect effect on preschoolers' critical thinking and caring thinking through preschoolers' executive function and counterfactual thinking; however, maternal reflective functioning had no indirect effect on preschoolers' creative thinking through preschoolers' executive function and counterfactual thinking. This study revealed that maternal reflective functioning and preschoolers' executive function and counterfactual thinking need to be considered simultaneously to explain the level of preschoolers' higher-order thinking. The results highlight the dual mediating effects of preschoolers' executive function and counterfactual thinking in the relationship between maternal reflective functioning and preschoolers' higher-order thinking.
