We offer a critical perspective on the meta-analysis by Elkjær et al. (2020) by pointing out three constraints: The first refers to open-science practices, the second addresses the selection of studies, and the third offers a broader theoretical perspective. We argue that preregistration and adherence to the highest standards of conducting meta-analyses is important. Further, we identified several missing studies. Regarding the theoretical perspective, we suggest that it may be useful to tie body positions into the dominance-prestige framework and, on that basis, to distinguish two types of body positions. Such an approach has the potential to account for discrepancies in previous meta-analytical evidence regarding the effects of expansive versus contractive nonverbal displays. Future research may thus be able to provide not only methodological but also theoretical innovations to the field of body positions.

我们对 Elkjær 等人的荟萃分析提出了批判性观点。（2020 年）通过指出三个限制：第一个是指开放科学实践，第二个涉及研究的选择，第三个提供更广泛的理论视角。我们认为，预先注册和遵守进行荟萃分析的最高标准很重要。此外，我们确定了几项缺失的研究。关于理论观点，我们建议将身体姿势与支配-声望框架联系起来，并在此基础上区分两种类型的身体姿势可能是有用的。这种方法有可能解释以前的元分析证据中关于扩张性与收缩性非语言展示的影响的差异。
