摘要:Objectives: To investigate the effects of humor styles used by parents toward their children on the latter’s emotion regulation competence, and the role of parents' warm parenting style in their relationships. Methods: The parents' humor style and warm parenting behavior and their children's emotion regulation competence were measured in 153 children aged 5-6 years, attending child care centers and kindergartens located in Seoul and Gyeong-gi regions, along with their parents, totaling to 459 participants. The collected data were analyzed using factor analysis, multiple regression analysis, and regression mediation analysis, with SPSS 21.0 program. Results: First, if the father used more social humor, or if the mother used more social and selfenhancing humor, the child was more likely to have high emotion regulation competence. Second, the parents using more social and self-enhancing humors and mothers using more aggressive humor were more likely to show warm parenting behavior. Third, the warm parenting behavior of the mother mediates the positive effect of her social and self-enhancing humor on her child's emotion regulation competence. Conclusions: The frequent use of social and self-enhancing humor by parents means that they express their own emotion after regulating it positively. The infants adaptively regulate their own emotions by learning the regulated emotions of their parents. In addition, this result suggests that mother's parenting behaviors are more influential on the child's development than father's parenting behaviors, despite women's active advancement into society and change in values of child-rearing.
