加拿大研究人员发现，在女性眼中，嗓音低沉的男性欺骗伴侣的可能性较高；而在男性看来，嗓音高的女性对伴侣忠诚度较低。

研究人员强调，嗓音并非一个人品性的必然证明，不忠不能归咎于生物学原因。心理学空间1B D-jDV;Z U

研究顾问、麦克马斯特大学心理学、神经学与行为学院副教授戴维范伯格告诉英国《每日邮报》记者：“嗓音高低影响忠诚度的原因可能在于音高、激素和不忠之间的关系。”

范伯格说：“睾丸素水平较高的男性嗓音较低沉，雌性激素水平较高的女性嗓音较高。这些激素水平高低与不忠行为有关。”心理学空间w ?Ki"y0n+Yi

Jillian J.M. O.Connor, Department of Psychology, Neuroscience and Behaviour, McMaster University, Hamilton, Canada.

(o R U"D+A~T$W0Abstract: Sexual infidelity can be costly to members of both the extra-pair and the paired couple. Thus, detecting infidelity risk is potentially adaptive if it aids in avoiding cuckoldry or loss of parental and relationship investment. Among men, testosterone is inversely related to voice pitch, relationship and offspring investment, and is positively related to the pursuit of short-term relationships, including extra-pair sex. Among women, estrogen is positively related to voice pitch, attractiveness, and the likelihood of extra-pair involvement. Although prior work has demonstrated a positive relationship between men.s testosterone levels and infidelity, this study is the first to investigate attributions of infidelity as a function of sexual dimorphism in male and female voices. We found that men attributed high infidelity risk to feminized women.s voices, but not significantly more often than did women. Women attributed high infidelity risk to masculinized men.s voices at significantly higher rates than did men. These data suggest that voice pitch is used as an indicator of sexual strategy in addition to underlying mate value. The aforementioned attributions may be adaptive if they prevent cuckoldry and/or loss of parental and relationship investment via avoidance of partners who may be more likely to be unfaithful.
