This study investigates the relations between two forms of joint action (JA)—movement coordination (MC) and goal attainment—and theory of mind (ToM), contrasting the interactionist and traditional cognitivist views. A custom task was carried out to measure the properties of the JAs between children and their parents, while classical tasks were performed to measure first- and second-order ToM. Thereafter, cross-recurrence quantification analysis was applied to quantify participants' movements. The children were from Poland and were aged 42, 66, and 78 months (N = 297, 133 girls, White, from a large city). The results suggested that the characteristics of dyad MC influence goal attainment and are related to children's first-order ToM (R² = .447) but not to their second-order ToM.

协调运动和信念：一起做事的不同方面

本研究调查了两种形式的联合行动 (JA)——运动协调 (MC) 和目标实现——与心智理论 (ToM) 之间的关系，对比了互动主义和传统认知主义的观点。执行自定义任务以测量儿童与其父母之间 JA 的属性，同时执行经典任务以测量一阶和二阶 ToM。此后，应用交叉重复量化分析来量化参与者的动作。这些孩子来自波兰，年龄分别为 42、66 和 78 个月（N  = 297，133 名女孩，白人，来自大城市）。结果表明，二元 MC 的特征影响目标达成，并与儿童的一阶 ToM ( R ² = .447) 但不是他们的二阶 ToM。
