This methodological paper examines the assessment of interpersonal synchrony during a joint dancing task between mothers and their children (aged 4 to 5 years) using OpenPose. This pose estimation tool captures movement in naturalistic settings. The study analyzes 45 mother-child dyads, comparing two analytical methods for assessing synchrony, and examines their correlation with the Coding Interactive Behavior (CIB) measure of interaction quality. The first method employs cross-wavelet transform (CWT) coherence to assess synchrony based on vertical head movement. This straightforward and computationally efficient approach reveals a significant correlation between interpersonal synchrony and CIB scores, thus implying its potential as a reliable indicator of interaction quality and suggesting its potential as a measure of interaction quality. The second method, the generalized cross-wavelet transform (GCWT), analyzes synchrony across multiple body parts, offering a more complex and detailed analysis of interpersonal dynamics. However, it did not significantly correlate with the CIB scores. Our findings suggest that focusing on head movement using CWT can effectively capture critical elements of interpersonal synchrony linked to interaction quality. In contrast, despite its richness, the more complex GCWT approach may not align as closely with observed interactive behaviors as the CIB scores indicate. This study underscores the need to balance methodological complexity and ecological validity in research, offering insights into selecting analytical techniques based on research objectives and the nuances of interpersonal dynamics. Our results contribute to the field of interpersonal synchrony research, emphasizing the benefits of efficient methods in understanding mother-child interactions and interaction relationships in general.
这篇方法学论文探讨了使用OpenPose对母亲及其4至5岁孩子在联合舞蹈任务中的人际同步性进行评估。这种姿态估计工具可捕捉自然场景中的动作。该研究分析了45对母婴二元组，比较了两种评估同步性的分析方法，并考察了它们与互动质量的编码互动行为（CIB）测量之间的相关性。第一种方法采用交叉小波变换（CWT）相干性，基于垂直头部运动来评估同步性。这种直接且计算效率高的方法揭示了人际同步性与CIB分数之间存在显著相关性，因此暗示了其作为互动质量可靠指标的潜力，并表明其作为互动质量度量的潜力。第二种方法，广义交叉小波变换（GCWT），分析多个身体部位的同步性，为人际动态提供了更复杂和详细的分析。然而，它与CIB分数没有显著相关性。我们的研究结果表明，使用CWT关注头部运动可以有效地捕捉与互动质量相关的人际同步性关键要素。相比之下，尽管GCWT方法丰富，但它可能与观察到的互动行为的契合度不如CIB分数所显示的那样紧密。这项研究强调了在研究中平衡方法复杂性和生态效度的必要性，为根据研究目标和人际动态细微差别选择分析技术提供了见解。我们的结果为人际同步性研究领域做出了贡献，强调了有效方法在理解母婴互动及一般互动关系方面的益处。
