Abstract: | Parental emotion socialization is a dynamic process encompassing moment‐to‐moment fluctuations in parents’ emotional displays and responsiveness. This study attempted to examine the within‐ and between‐individual variation in fathers’ emotional expressivity during a real‐time father–child interaction in Chinese families. Eighty‐five children (Mage = 7.58 years, SD = 0.50 years, 47.1% boys) from east China and their biological fathers participated in the study. Fathers’ and children’s emotional expressivity were observed during a problem‐solving interaction task. Fathers’ beliefs about children’s negative emotions and fathers’ perceptions of their children’s emotion regulation ability were assessed via self‐report questionnaires. Results showed that (1) At the within‐individual level, fathers’ and children’s emotional expressivity covariated with each other in concurrent intervals when controlling for their emotional expressivity in previous intervals; fathers’ emotional expressivity gradually became less positive over time whereas children’s emotional expressivity did not change significantly over time; (2) At the between‐individual level, fathers’ perceptions of children’s emotion regulation accounted for the between‐individual variance in the dynamics of fathers’ emotional expressivity. These findings chart the dynamics of paternal emotion expressivity during father–child interactions and shed light on the relevant roles of children’s emotional expressivity and fathers’ emotion‐related beliefs and perceptions. |
