Recently, heart rate variability (HRV) level has been found to be a risk factor for female sexual dysfunction. Low HRV was a significant predictor of female sexual arousal dysfunction and overall sexual dysfunction. Building upon this finding, the present study examined whether differences in vagal activity between sexually functional and sexually dysfunctional women may be driving the associat...

In general, spiders are considered to exhibit resting metabolic rates about half of those measured for other poikilothermic animals of equal mass (e .g ., Anderson 1970; Greenstone & Bennett 1980; Anderson & Prestwich 1982 ; Anderson 1987; Paul et al. 1989; Anderson 1996). However, these metabolic rates were all compared to Hemmingsen's poikilotherm mass-scaling equation (1960), which has recen...

Regret and anticipated regret enhance decision quality by helping people avoid making and repeating mistakes. Some of people's most intense regrets concern sexual decisions. We hypothesized evolved sex differences in women's and men's experiences of sexual regret. Because of women's higher obligatory costs of reproduction throughout evolutionary history, we hypothesized that sexual actions, par...

Despite extensive research examining the correlates of unintended fertility, it remains a puzzle as to why racial and ethnic minorities are more likely to experience an unintended birth than non-Hispanic whites. This paper focuses on sexual literacy, a potential precursor of unintended fertility. Analyses use a unique dataset of unmarried young adults aged 18-29, the 2009 Survey of Unmarried Yo...

This study analyzes the relation of sexual orientation and gender to sexual sensation seeking. Participants were 382 individuals (200 men, 182 women) between 17 and 29 years old who completed the Sexual Sensation Seeking Scale. Of the 382 participants, 52.46% self-reported heterosexual orientation, and 47.64% self-reported homosexual orientation. The results showed differences with Sexual Sensa...

INTRODUCTION Recently, McCall and Meston presented an assessment tool for empirically categorizing stimuli associated with sexual desire in women. Significant differences in cues resulting in sexual desire were found between women with and without hypoactive sexual desire disorder (HSDD). AIM The present study examined differences in cues resulting in sexual desire between pre- and postmenopa...
