In this study, we examined the effects of parental self-monitoring and the "accompanying perception," which is the ability of parents to understand their children's behavior as a result of their child-rearing behavior from a bird's-eye view, on functional child-rearing behavior. The results showed that even mothers with low self-monitoring skills were able to carry out functional child-rearing behaviors related to "communication" if they had a high "accompanying perception. In future child-rearing support, it is thought that the mothers' acquisition of appropriate accompanying perception can be assessed to promote the performance of functional child-rearing behaviors in accordance with their children's actual reactions.
