Intrasexual Competition: Effects Of Hormonal Contraceptives, Hannah Fergusson
Intrasexual Competition: Effects Of Hormonal Contraceptives, Hannah Fergusson
Cal Poly Humboldt theses and projects
Women’s intrasexual competition has been shown to fluctuate with fertility status, and in particular, with testosterone. It’s increasingly common that women take some form of hormonal contraceptives, especially the combined oral contraceptive (COC) pill which has been shown to decrease testosterone levels. Progesterone-only methods such as the implant or shot have been shown to have higher levels of free testosterone compared to the pill. The current study investigates the differences in intrasexual competition between pill users and progesterone-only users. 773 women took several surveys that obtained their information regarding menstrual cycle, contraceptive use, relationship status, and also took the Scale …
Cuteness As A Prime To Enhance Emotional Recognition, Andrew Diaz
Cuteness As A Prime To Enhance Emotional Recognition, Andrew Diaz
Cal Poly Humboldt theses and projects
The ability to recognize emotional expressions has important implications for survival and cooperation. Failing to recognize emotions indicative of some form of threat (anger, fear, disgust) may be particularly costly given these emotional expressions communicate a potential source of danger in the environment. Previous studies have shown that people tend to recognize threatening emotions faster and more accurately than non-threatening emotions. Infantile characteristics (kindchenschema) readily capture the attention of adults and have been shown to influence a variety of behaviors associated with caretaking; viewing cute stimuli increases behavioral carefulness on various visual and motor tasks. The current study …
Does Testosterone Affect Sexist Attitudes In Men? A Simulated Analysis, Steven R. Bowman
Does Testosterone Affect Sexist Attitudes In Men? A Simulated Analysis, Steven R. Bowman
Cal Poly Humboldt theses and projects
Sexism continues to negatively affect the lives of women across many cultures and modern societies. Although sexism has a damaging effect on people overall, women are disproportionately affected. Previous research on the topic generally explores attitudes, culture, socioeconomic status, sexual and violent crime census data, and developmental factors, but there is a lack of research investigating potential links among biological factors, such as hormone levels, and sexist attitudes. The present study used simulated data to simulate a study investigating the relationship between endogenous testosterone, cognitive aggression, and sexist attitudes. Using the faux, pwr2ppl, and ProcessR packages in R Studio open-source …

Does Pregnancy Enhance Sensitivity To Emotional Displays Of Threat?, Lauren E. Larsen
Cal Poly Humboldt theses and projects
The human face provides us with an abundant amount of social and biological information. It is important for us to be able to recognize emotions quickly and accurately, some emotions may be more important and therefore draw more of our attention than others, specifically “threat-relevant” emotions (fear, disgust, anger). To date few studies have investigated how pregnancy impacts emotion recognition abilities. These studies have shown that women have higher accuracy in encoding emotional expressions signaling threat or harm. To determine if pregnancy increases attentional bias to threat, 43 pregnant women and 45 non-pregnant women (controls) performed an emotion recognition task. …
