Dominance and prestige: Meta-analytic review of experimentally induced body position effects on behavioral, self-report, and physiological dependent variables.
Psychological Bulletin ( IF 22.4 ) Pub Date : 2022-05-12


Early research on body positions suggested that engaging in certain nonverbal displays can lead to changes in self-report, behavioral, and physiological dependent variables. Still, there has been intense criticism regarding the replicability of these effects. To determine what effects are valid, we conducted a meta-analytic review on body position studies. We used the dominance–prestige framework and distinguished between high-power poses representing dominance and upright postures representing prestige. We preregistered our meta-analysis, used the largest sample of studies thus far, and analyzed several theoretical and exploratory moderator variables. Based on 313 effects from 88 studies involving 9,779 participants, evidence was obtained for an overall statistically significant effect of body positions that was not trivial in size, g = 0.35 (95% CI [0.28,0.42]). Both the poses and postures showed effects for self-report and behavioral dependent variables but not for physiological dependent variables. However, sensitivity analyses suggested that effects for behavioral dependent variables were influenced by publication bias and/or outliers. Effects were noticeably larger in studies without cover stories and in studies that used within-subjects designs, suggesting that demand characteristics might partially explain the results. Whether participants were male or female, students or nonstudents, or from an individualistic or collectivistic culture did not make a difference. We also present an app that researchers can use to enter data from future studies and thus obtain up-to-date meta-analytical results on this topic. Future research should investigate whether high-power poses/upright postures increase effects and/or whether low-power poses/slumped postures decrease effects.

支配地位和声望:对实验诱导的身体位置对行为、自我报告和生理因变量的影响的荟萃分析回顾。

对身体姿势的早期研究表明,参与某些非语言展示会导致自我报告、行为和生理因变量的变化。尽管如此,关于这些效果的可复制性仍然存在激烈的批评。为了确定哪些影响是有效的,我们对身体姿势研究进行了荟萃分析审查。我们使用支配-声望框架,区分代表支配的高功率姿势和代表声望的直立姿势。我们预先注册了我们的荟萃分析,使用了迄今为止最大的研究样本,并分析了几个理论和探索性调节变量。基于涉及 9,779 名参与者的 88 项研究的 313 项效应,我们获得了身体姿势的总体统计显着效应的证据,该效应在大小上并非微不足道,g = 0。35 (95% CI [0.28,0.42])。姿势和姿势都显示出对自我报告和行为因变量的影响,但对生理因变量没有影响。然而,敏感性分析表明,行为因变量的影响受到发表偏倚和/或异常值的影响。在没有封面故事的研究和使用受试者内部设计的研究中,效果明显更大,这表明需求特征可能部分解释了结果。参与者是男性还是女性,学生还是非学生,或者来自个人主义或集体主义文化都没有影响。我们还提供了一个应用程序,研究人员可以使用该应用程序输入来自未来研究的数据,从而获得关于该主题的最新元分析结果。
