Both facial width-to-height ratio (fWHR) and body mass index (BMI) have been associated with aggressive behavior in women but how they influence perception of their potential threat remain unclear. Here, we assessed the effects of fWHR and BMI on perceived formidability from faces of 42 female Ultimate Fighting Championship (UFC) fighters. In study 1, BMI, but not fWHR, positively predicted participants' ratings of aggressiveness and fighting ability from facial photographs. In study 2, both high fWHR and high BMI composite faces were rated as more aggressive, tougher, and more likely to win a fight than low fWHR and low BMI composite faces, respectively. Further analyses revealed that the high BMI composite face was rated as more aggressive and tougher than the high fWHR composite face. Taken together, these results suggest that compared to fWHR, BMI may be a more salient cue to women's formidability.
面部宽高比（fWHR）和体重指数（BMI）都与女性的攻击行为有关，但它们如何影响对其潜在威胁的感知尚不清楚。在这里，我们评估了 fWHR 和 BMI 对面孔可畏性的影响，这些面孔来自 42 位终极格斗冠军赛（UFC）女拳手。在研究 1 中，BMI 而不是 fWHR 正面预测了参与者对面部照片的侵略性和战斗能力的评分。在研究 2 中，高 fWHR 和高 BMI 的复合面孔分别比低 fWHR 和低 BMI 的复合面孔被评为更具攻击性、更坚韧、更有可能赢得比赛。进一步的分析表明，高 BMI 复合面孔比高 fWHR 复合面孔更具攻击性和坚韧。综上所述，这些结果表明，与 fWHR 相比，BMI 可能是女性可畏性的更明显线索。
