The present study investigated the comparability of two video-based tracking techniques, namely, Motion Energy Analysis and OpenPose, in the context of nonverbal synchrony research. Participants aged 23–69 years held a 15-min unstructured conversation with a same-gender partner of the same generation. Each participant’s movements were quantified with two algorithms, which were separately submitted to a wavelet transform to assess synchrony between the partners. Wavelet coherence and information in the relative phase were used to measure the intensities and patterns of synchrony, respectively. As a benchmark of the test results, gender effects and correlation with the Big Five personality traits were examined. Irrespective of the tracking technique used, the results consistently illustrated gender effects: female dyads showed more synchrony than male dyads. Among the Big Five personality traits, only Extraversion was significantly associated with synchrony in either tracking technique. The gender effect remained significant in both the tracking techniques even when controlling for personality traits, indicating that both individual (i.e., personality) and social (i.e., gender) factors contribute to synchrony. The use of video-tracking techniques in the research on synchrony for future studies was also discussed.

本研究在非语言同步研究的背景下调查了两种基于视频的跟踪技术，即运动能量分析和 OpenPose 的可比性。年龄在 23-69 岁的参与者与同代的同性伴侣进行了 15 分钟的非结构化对话。每个参与者的动作都用两种算法量化，分别提交给小波变换以评估合作伙伴之间的同步性。小波相干性和相对相位的信息分别用于测量同步的强度和模式。作为测试结果的基准，研究了性别效应和与大五人格特征的相关性。无论使用何种跟踪技术，结果都一致地说明了性别影响：女性二人组比男性二人组表现出更多的同步性。在大五人格特质中，只有外向性与两种追踪技术的同步性显着相关。即使在控制人格特征时，性别效应在两种跟踪技术中仍然显着，这表明个人（即人格）和社会（即性别）因素都有助于同步。还讨论了视频跟踪技术在未来研究同步研究中的使用。性别）因素有助于同步。还讨论了视频跟踪技术在未来研究同步研究中的使用。性别）因素有助于同步。还讨论了视频跟踪技术在未来研究同步研究中的使用。
