Longitudinal data were obtained from 157 children aged 3 years 3 months to 5 years 6 months at Time 1. At Time 2 these children had aged an average of 12 months. Theory of mind (ToM) and executive functioning (EF) were measured at both time points. Results suggest that Time 1 ToM scores predict Time 2 EF scores. Detailed examination of sibling influences suggests that benefits-in terms of advanced ToM development-accrue to children with siblings versus without, and to those with a larger number of child-aged siblings. Any advance in either area (ToM or EF) is likely to benefit the other, and early sibling interaction appears to act as a catalyst.
研究从 157 名 3 岁 3 个月至 5 岁 6 个月大的儿童中获得了纵向数据。在时间 2 时，这些儿童的年龄平均增加了 12 个月。在两个时间点都测量了心理理论（ToM）和执行功能（EF）。结果表明，时间 1 的 ToM 分数预测了时间 2 的 EF 分数。对兄弟姐妹影响的详细研究表明，与没有兄弟姐妹的儿童相比，有兄弟姐妹的儿童，以及兄弟姐妹数量较多的儿童，在高级 ToM 发展方面受益更多。这两个领域（ToM 或 EF）的任何进展都可能使另一个领域受益，早期的兄弟姐妹互动似乎起到了催化剂的作用。
