Manipulations of fundamental and formant frequencies influence the attractiveness of human male voices
In human voices, low fundamental frequency is thought to be a cue to masculinity and reproductive capability and large vocal tracts are associated with large body size of the speaker. FemaleExpand
Menstrual cycle, trait estrogen level, and masculinity preferences in the human voice
It was found women displayed general masculinity preferences for men's voices; masculinity preferences were greater in the fertile (late-follicular) phase of the cycle than the non-fertile (early- follicular and luteal) phase; and this effect was most pronounced for women with low average E3G concentration.

Commitment to relationships and preferences for femininity and apparent health in faces are strongest on days of the menstrual cycle when progesterone level is high
It is found that women's preferences for social cues associated with possible direct benefits and commitment to relationships are strongest during conditions characterized by raised progesterone level, while attraction to men displaying cues related to possible indirect benefits is strongest when women are most fertile.

Facial appearance is a cue to oestrogen levels in women
It is demonstrated that female facial appearance holds detectable cues to reproductive health that are considered attractive by other people. Expand
Correlated preferences for facial masculinity and ideal or actual partner's masculinity
It is shown that women's preferences for masculinity manipulated in male faces using techniques similar to the three most widely used methods are positively inter-related and positively related to ratings of the masculinity of their actual partner and their ideal partner. Expand
Menstrual cycle, pregnancy and oral contraceptive use alter attraction to apparent health in faces
Findings indicate raised progesterone level is associated with increased attraction to facial cues associated with possible direct benefits and suggest that women's face preferences are influenced by adaptations that compensate for weakened immune system responses during pregnancy and reduce the risk of infection disrupting foetal development.

Voice pitch influences voting behavior
It may be adaptive for voters to recognize good leadership qualities among politicians. Men with lower-pitched voices are found to be more dominant and attractive than are men with higher-pitchedExpand
Raised salivary testosterone in women is associated with increased attraction to masculine faces
These findings complement those from previous studies that show systematic variation in masculinity preferences during the menstrual cycle and suggest that change in testosterone level may play an important role in cyclic shifts in women's preferences for masculine traits. Expand
Symmetry Is Related to Sexual Dimorphism in Faces: Data Across Culture and Species
The findings support the claim that sexual dimorphism and symmetry in faces are signals advertising quality by providing evidence that there must be a biological mechanism linking the two traits during development and suggest that the signalling properties of faces are universal across human populations and are potentially phylogenetically old in primates. Expand
Facial cues of dominance modulate the short-term gaze-cuing effect in human observers
The findings suggest that the mechanisms that underpin reflexive gaze cuing evolved to be sensitive to facial cues of others’ dominance, potentially because such differential gaze cued promoted desirable outcomes from encounters with dominant individuals. Expand
