The Negative Effect of Siblings on Perspective-Taking in Adulthood under Chinese Culture.

ABSTRACT

Evidence from Western developed countries has consistently found that children with sibling(s) showed better perspective-taking (PT) than only children. However, this was not the case in developing countries like China. Our study investigates whether the potentially hindering effect of having sibling(s) on PT persists into adulthood within the context of contemporary Chinese culture. We employed self-report questionnaires to measure PT, perceived parental care, and sibling relationships among Chinese young adults (21.93 ± 2.35 years old). Our findings indicate that in China, (1) having sibling(s) hinders individuals' PT in adulthood, (2) a potential mechanism for this effect is that having sibling(s) leads individuals to perceive less parental care during early life, and (3) for those with sibling(s), higher sibling intimacy can enhance PT, particularly among older sister-younger brother pairs. These results suggest that in developing countries such as China, while sibling(s) may diminish PT to some extent, factors like parental care and sibling intimacy can serve as protective factors that mitigate the negative impacts of sibling(s) on PT.
