The Effects Of Oral Contraceptives On Mood And Affect: A Meta-Analysis, Erica M. Motter
The Effects Of Oral Contraceptives On Mood And Affect: A Meta-Analysis, Erica M. Motter
Cal Poly Humboldt theses and projects
Combined oral contraceptive (COC) pills are widely used by women of reproductive age, but there is still little conclusive evidence that exists about the mood-related side effects associated with their use. This meta-analysis examined the relationship between oral contraceptive use and mood effects such as depression and anxiety to determine what role, if any, that COCs may have in the worsening or improvement of women’s mood when taking them. Effect sizes compared the differences in women’s mood scores before taking COCs and after one or more cycles of use. Seventeen studies made up of 25 individual samples contributed 71 effect …

Orgasms and ejaculation are important for relationships and contribute significantly to life satisfaction. There is, however, a lack of research in the current literature regarding orgasm perception. This study tested the effects of endogenous oxytocin on subjective orgasm intensity, ejaculation latency, and ejaculate volume in men. At two separate test sessions, the participants were either stroked on the forearm (to release endogenous oxytocin) or tapped on the hand (to act as a control) with a cosmetic brush. The forearm contains C-tactile afferents that are believed to release oxytocin centrally and peripherally in response to slow, soft stroking stimulation. Then a …
Eye Movements For Learned Faces, Mariah Lehnertz
Eye Movements For Learned Faces, Mariah Lehnertz

Humans demonstrate a perceptual specialization for faces that is astonishing. This project attempts determine if and where within the perceptual process face perception and face recognition diverge at the level of eye movement behaviors. Participants were exposed to a series of 36 faces, of which six were randomly selected to be learned over five subsequent exposures; thus the same face identities served as both the novel faces (block 1) and the learned faces (block 5), allowing for the measurement of eye gaze patterns during initial face perception (novel) and face recognition (learned). These six faces were randomly assigned to different …

"I See Gay People" Gaydar Abilities In A Real-World Distribution, Benjamin Patrick Skillman

“Gaydar” is the colloquial term for identifying someone’s sexual orientation from physical cues. Past literature has shown that people can identify someone’s sexual orientation at above chance levels. Past literature has used a 50/50 split of gay and straight faces and used non-standardized images, which can induce confounds in the results. The present study examined gaydar accuracy in a realistic distribution of straight and gay faces using standardized images and examined facial morphology for differences between gay and straight men. Participants were not found to have above chance accuracy for identifying gay faces. PCA did not identify reliable shape differences …
