    Much attractiveness research has focused on face shape. The role of masculinity (which for adults is thought to be a relatively stable shape cue to developmental testosterone levels) in male facial attractiveness has ...
  • Cross-cultural variation in women’s preferences for cues to sex- and stress-hormones in the male face 
    Moore, Fhionna R.; Coetzee, Vinet; Contreras-Garduno, J.; DeBruine, L.M.; Kleisner, K.; Krams, Indrikis; Marcinkowska, U.; Nord, A.; Perrett, David Ian; Rantala, Markus J.; Schaum, N.; Suzuki, T.N. (The Royal Society, 2013)
    Women in the UK prefer the faces of men with low levels of the stress hormone cortisol, and the relationship is moderated by the sex hormone testosterone. In a Latvian sample, however, women’s preferences were not affected ...
  • Dysbiosis signatures of fecal microbiota in South African infants with respiratory, gastrointestinal, and other diseases

  • Effect of beta-carotene supplementation on African skin 
    Coetzee, Vinet; Perrett, David Ian (Society of Photo-Optical Instrumentation Engineers (SPIE), 2014-02)
    The quantification of skin carotenoid levels has a range of applications in Caucasian populations, from serving as a versatile and noninvasive biomarker (e.g., of systemic carotenoid levels, carotenoid consumption, the ...
  • Effects of varying the color, aroma, bitter and sweet levels of a grapefruit-like model beverage on sensory properties and consumer liking 
    Gous, Andries Gustav Stefanus; Almli, Valerie L.; Coetzee, Vinet; De Kock, Henrietta Letitia (MDPI, 2019-02)
    Color, aroma, sweet, and bitter tastes contribute to the sensory perception of grapefruit juice. Consumers differ about liking grapefruit. A reason is the bitter taste that characterize the fruit. The objective was to ...
  • Facial adiposity, attractiveness, and health : a review 
    De Jager, Stefan; Coetzee, Nicoleen; Coetzee, Vinet (BioMed Central, 2018-12-21)
    The relationship between facial cues and perceptions of health and attractiveness in others plays an influential role in our social interactions and mating behaviors. Several facial cues have historically been investigated ...
  • Facial appearance reveals immunity in African men 
    Phalane, Khutso G.; Tribe, Catherine; Steel, Helen C.; Cholo, Moloko C.; Coetzee, Vinet (Nature Publishing Group, 2017-08-07)
    Facial appearance is thought to indicate immunity in humans, but very few studies have tested this relationship directly. The aim of this study was to test the relationship between direct measures of immunity, perceived ...
  • Facial attractiveness is related to women’s cortisol and body fat, but not with immune responsiveness 
    Rantala, Markus J.; Coetzee, Vinet; Moore, Fhionna R.; Skrinda, Ilona; Kecko, Sanita; Krama, Tatjana; Kivleniece, Inese; Krams, Indrikis (The Royal Society, 2013-08)
    Recent studies suggest that facial attractiveness indicates immune responsiveness in men and that this relationship is moderated by stress hormones which interact with testosterone levels. However, studies testing whether ...
  • Facial shape analysis identifies valid cues to aspects of physiological health in Caucasian, Asian, and African populations 
    Stephen, Ian D.; Hiew, Vivian; Coetzee, Vinet; Tiddeman, Benard P.; Perrett, David I. (Frontiers Research Foundation, 2017-10-30)
