5 Things That Internet Porn Reveals About Our Brains | Sex & the Brain | DISCOVER Magazine - 1 views

  •  
    With its expansive range and unprecedented potential for anonymity, (the Internet gives voice to our deepest urges and most uninhibited thoughts. Inspired by the wealth of unfettered expression available online, neuroscientists Ogi Ogas and Sai Gaddam, who met as Ph.D. candidates at Boston University, began plumbing a few chosen search engines (including Dogpile and AOL) to create the world's largest experiment in sexuality in 2009. Quietly tapping into a billion Web searches, they explored the private activities of more than 100 million men and women around the world. The result is the first large-scale scientific examination of human sexuality in more than half a century, since biologist Alfred Kinsey famously interviewed more than 18,000 middle-class Caucasians about their sexual behavior and published the Kinsey reports in 1948 and 1953. Building on the work of Kinsey, neuroscientists have long made the case that male and female sexuality exist on different planes. But like Kinsey himself, they have been hampered by the dubious reliability of self-reports of sexual behavior and preferences as well as by small sample sizes. That is where the Internet comes in. By accessing raw data from Web searches and employing the help of Alexa-a company that measures Web traffic and publishes a list of the million most popular sites in the world-Ogas and Gaddam shine a light on hidden desire, a quirky realm of lust, fetish, and kink that, like the far side of the moon, has barely been glimpsed. Here is a sampling of their fascinating results, selected from their book, A Billion Wicked Thoughts.

Boys reach sexual maturity younger and younger: Phase between being physically but not ... - 0 views

  •  
    ScienceDaily (Aug. 19, 2011) - Boys are maturing physically earlier than ever before. The age of sexual maturity has been decreasing by about 2.5 months each decade at least since the middle of the 18th century. Joshua Goldstein, director of the Max Planck Institute for Demographic Research in Rostock (MPIDR), has used mortality data to demonstrate this trend, which until now was difficult to decipher. What had already been established for girls now seems to also be true for boys: the time period during which young people are sexually mature but socially not yet considered adults is expanding.

Does sexual equality change porn? - Pornography - Salon.com - 0 views

  •  
    In what may feel like a flashback to the porn wars of the '60s, a new study investigates the link between a country's relative gender equality and the degree of female "empowerment" in the X-rated entertainment it consumes. Researchers at the University of Hawaii focused on three countries in particular: Norway, the United States and Japan, which are respectively ranked 1st, 15th and (yikes) 54th on the United Nations' Gender Empowerment Measure (GEM). To simplify their analysis, their library of smut was limited to explicit photographs of women "from mainstream pornographic magazines and Internet websites, as well as from the portfolios of the most popular porn stars from each nation." Then they set out to evaluate each image on both a disempowerment and an empowerment scale, using respective measures like whether the woman is "bound and dominated" by "leashes, collars, gags, or handcuffs" or "whether she has a natural looking body." Their hypothesis was that societies with greater gender equity will consume pornography that has more representations of "empowered women" and less of "disempowered women." It turned out the former was true, but, contradictory as it may sound, the latter was not. "While Norwegian pornography offers a wider variety of body types -- conforming less to a societal ideal that is disempowering to the average woman -- there are still many images that do not promote a healthy respect for women," the researchers explain. In other words, Norwegian porn showed more signs of female empowerment, but X-rated images in all three countries equally depicted women in demeaning positions and scenarios. This, the researchers surmise, "suggests that empowerment and disempowerment within pornography are potentially different constructs." So, gender equality is accompanied by sexual interest in a broader range of beauty types but not a decrease in porn's infantilization of females, use of dominating fetish gear on women or any of the other characteristics th

Studies suggest males have more personality - 0 views

  •  
    "Males have more pronounced personalities than females across a range of species - from humans to house sparrows - according to new research. Consistent personality traits, such as aggression and daring, are also more important to females when looking for a mate than they are to males. Research from the University of Exeter draws together a range of studies to reveal the role that sexual selection plays in this disparity between males and females."

Official SCIENCE*: HIGH HEELS make you SEXY (Ladies) * The Register - 0 views

  •  
    "There is a strong contemporary association between high heels and female sexuality. We investigated the hypothesis that one motivation for women wearing high heels is that it artificially increases the femininity of gait. Biomechanical analyses revealed that wearing high heels led to increased femininity of gait including reduced stride length and increased rotation and tilt of the hips. This groundbreaking study was published this month in the scientific journal Evolution and Human Behavior. It was written by Paul H. Morris, Jenny White, Edward R. Morrison and Kayleigh Fisher"

New Theory on Why Men Love Breasts | Breast Evolution | LiveScience - 0 views

  •  
    "But Young's new theory will face scrutiny of its own. Commenting on the theory, Rutgers University anthropologist Fran Mascia-Lees, who has written extensively about the evolutionary role of breasts, said one concern is that not all men are attracted to them. "Always important whenever evolutionary biologists suggest a universal reason for a behavior and emotion: how about the cultural differences?" Mascia-Lees wrote in an email. In some African cultures, for example, women don't cover their breasts, and men don't seem to find them so, shall we say, titillating. Young says that just because breasts aren't covered in these cultures "doesn't mean that massaging them and stimulating them is not part of the foreplay in these cultures. As of yet, there are not very many studies that look at [breast stimulation during foreplay] in an anthropological context," he said. Young elaborates on his theory of breast love, and other neurological aspects of human sexuality, in a new book, "The Chemistry Between Us" (Current Hardcover, 2012), co-authored by Brian Alexander."

    Recent formulations of sexual selection theory emphasise how mate choice can be affected by environmental factors, such as predation risk and resource quality. Women vary greatly in the extent to which they prefer male masculinity and this variation is hypothesised to reflect differences in how women resolve the trade-off between the costs (e.g., low investment) and benefits (e.g., healthy offspring) associated with choosing a masculine partner. A strong prediction of this trade-off theory is that women's masculinity preferences will be stronger in cultures where poor health is particularly harmful to survival. We investigated the relationship between women's preferences for male facial masculinity and a health index derived from World Health Organization statistics for mortality rates, life expectancies, and the impact of communicable disease. Across 30 countries, masculinity preference increased as health decreased. This relationship was independent of cross-cultural differences in wealth or women's mating strategies. These findings show non-arbitrary cross-cultural differences in facial attractiveness judgments and demonstrate the utility of trade-off theory for investigating cross-cultural variation in women's mate preferences.

Sex and the Red Queen hypothesis | KurzweilAI - 1 views

  •  
    The hypothesis suggests that sexual reproduction via cross-fertilization keeps host populations one evolutionary step ahead of the parasites, which are frantically co-evolving to infect them. So both hosts and parasites are running (evolving) as fast as they can just to stay in the same place.
