目的比较研究表明，男性求爱对女性表现出条件依赖的信号特征，这些特征也可能为潜在的男性竞争者提供线索。尽管已经发现了人体运动与身体/行为品质之间的一些关联，但这类研究通常只从女性配偶选择的角度进行。在这里，使用先进的动作捕捉和生物力学分析，我们检查了男性舞蹈在多大程度上向男性和女性提供了关于舞者身体素质的线索。方法使用动作捕捉技术记录了30名1937岁的男性在标准节奏下跳舞的动作。参与者还完成了血管健康测试，评估了上半身和下半身的力量，并从他们的舞蹈动作中提取了生物力学指标。舞蹈片段被转换成虚拟的人形角色(化身)，并由27名女性和21名男性根据感知的舞蹈质量进行评分。结果普通线性混合模型显示，舞者的握力和手臂动作都是舞蹈质量评分的显著预测因子；更强壮的男性表现出更大、更多变和更快的手臂动作被评为更好的舞者。观察者的性别对舞蹈质量评分的预测没有影响，这表明男性和女性观察者对舞蹈质量的评价是相同的。身体健康与感知的舞蹈质量没有关联。结论男性和女性能够通过观察男性舞蹈动作以受控刺激的形式获得一定质量的线索。因此，男性舞蹈可能会对配偶质量的某些方面形成一种条件依赖的装饰。上午好。J.嗯。比奥尔。2013年25：307312。(C)2013年威利期刊公司。
Objectives Comparative research suggests that male courtship displays signal condition-dependent traits tofemales; these displays might also provide cues to potential male competitors. Although some associations betweenhuman movements and physical/behavioral qualities have been found, such research has typically only been conducted from a perspective of female mate choice. Here, using advanced motion capture and biomechanical analyses, we examine the extent to which male dancing provides cues about the dancer's physical qualities to both males and females. Methods Thirty men aged 1937 were recorded using motion-capture technology as they danced to a standard rhythm. Participants also completed a vascular fitness test, assessments of upper- and lower-body strength, and biomechanical indices were extracted from their dance movements. Dance clips were converted into virtual humanoid characters (avatars) and rated by 27 women and 21 men on perceived dance quality. Results General linear mixed modeling revealed that both handgrip strength and arm movements of the dancer were statistically significant predictors of dance quality ratings; stronger males who displayed larger, more variable, and faster movements of their arms being rated as better dancers. There was no effect of the sex of the observer in predicting dance quality ratings, indicating that male and female observers rated dance quality equivalently. Physical fitness was not associated with perceived dance quality. Conclusions Men and women are able to derive certain quality cues from observing male dance movements in the form of controlled stimuli. Thus, male dancing may form a condition-dependent ornament of certain aspects of mate quality. Am. J. Hum. Biol. 25:307312, 2013. (c) 2013 Wiley Periodicals, Inc.
