Affiliative Response to Stress: an empirical investigation of Tend-and-Befriend model (2018)
Presentation / Conference Contribution
Karastoyanova, K. V., & Sharp, M. A. (2018, July). Affiliative Response to Stress: an empirical investigation of Tend-and-Befriend model. Poster presented at 30th annual meeting of the Human Behavior and Evolution Society, Amsterdam

Stress research in humans has been considered predominantly within the conceptual framework of Cannon’s Fight-or-Flight model. However, observations that it was primarily tested on males led to the development of the tend-befriend model in females (T...

Female Gaze Behaviour, Status and the Menstrual Cycle: An Exploratory Study (2017)
Presentation / Conference Contribution
Sharp, M. A., & Hamilton, G. E. (2016, August). Female Gaze Behaviour, Status and the Menstrual Cycle: An Exploratory Study. Presented at XXIII ISHE Congress, Stirling, Scotland

Whilst not explaining all social behaviour and organisation, dominance is nevertheless an important dimension of human social interaction. It has been hypothesized that gaze behaviour reflects the dominance hierarchy of primate groups and several stu...

Female salivary testosterone: the influence of circadian dynamics on sampling strategies in bio-behavioural research (2015)
Presentation / Conference Contribution
Sharp, M. (2015, September). Female salivary testosterone: the influence of circadian dynamics on sampling strategies in bio-behavioural research. Poster presented at Society for the Study of Human Biology (SSHB), Lisbon, Portugal

Women's biology has been used as a powerful justification for social inequality (Fausto-Sterling, 1992). However, evolutionary arguments suggesting females are unlikely to be equipped biologically for status and dominance remain controversial and unr...

Sex-Role Orientation in Men Is Related to Salivary Testosterone Levels (2013)
Journal Article
Smith, M. J. L., Deady, D. K., Sharp, M. A., & Al-Dujaili, E. A. S. (2013). Sex-Role Orientation in Men Is Related to Salivary Testosterone Levels. Journal of Behavioral and Brain Science, 3(7), 518-521. https://doi.org/10.4236/jbbs.2013.37054

Previous research has implicated the involvement of androgens in sex-role orientation in males, from studies of 2 nd to 4 th digit ratio (a purported marker of prenatal testosterone). The present pilot study investigates the relationship between sali... Read More about Sex-Role Orientation in Men Is Related to Salivary Testosterone Levels.

Cues to sex- and stress-hormones in the human male face: Functions of glucocorticoids in the immunocompetence handicap hypothesis (2011)
Journal Article
Moore, F., Al Dujaili, E., Cornwell, R., Smith, M. L., Lawson, J., Sharp, M., & Perrett, D. (2011). Cues to sex- and stress-hormones in the human male face: Functions of glucocorticoids in the immunocompetence handicap hypothesis. Hormones and Behavior, 60(3), 269-274. https://doi.org/10.1016/j.yhbeh.2011.05.010

The stress-linked version of the immunocompetence handicap hypothesis has been proposed to account for inconsistencies in relationships between testosterone and immune response. The model has received some support from studies demonstrating roles of...

Evidence for the stress-linked immunocompetence handicap hypothesis in human male faces (2010)
Journal Article
Moore, F. R., Cornwell, R. E., Law Smith, M. J., Al Dujaili, E. A. S., Sharp, M., & Perrett, D. I. (2011). Evidence for the stress-linked immunocompetence handicap hypothesis in human male faces. Proceedings of the Royal Society B: Biological Sciences, 278(1706), 774-780. https://doi.org/10.1098/rspb.2010.1678

The stress-linked immunocompetence handicap hypothesis (SL-ICHH) of sexual selection incorporates a role of the stress hormone corticosterone (C; cortisol in humans) in relationships between testosterone (T), immunity and secondary sexual trait expre...

Raised salivary testosterone in women is associated with increased attraction to masculine faces (2007)
Journal Article
Welling, L., Jones, B., DeBruine, L., Conway, C., Law Smith, M., Little, A., Feinberg, D., Sharp, M., & Al-Dujaili, E. (2007). Raised salivary testosterone in women is associated with increased attraction to masculine faces. Hormones and Behavior, 52(2), 156-161. https://doi.org/10.1016/j.yhbeh.2007.01.010

Women's preferences for masculinity in men's faces, voices and behavioral displays change during the menstrual cycle and are strongest around ovulation. While previous findings suggest that change in progesterone level is an important hormonal mechan...
