The research highlights the need for a broader understanding of sexual behaviors in domestic violence prevention programs.
A new survey of over 850 US women found that relaxing beach vacations are perfect for sexual experimentation with a steady partner, while group tours and sightseeing trips are ideal for casual sex with acquaintances or strangers. Women tend to underestimate risks in non-penetrative activities and overestimate condom protection.
Adolescents with weaker working memory are more likely to have difficulty controlling impulsive tendencies, leading to early and unprotected sex. Improvements in working memory may provide a pathway to greater control over risky sexual behavior.
Research suggests pedophiles are more likely to have minor physical anomalies in the face and head, developing during the prenatal period. The study found a higher prevalence of these deviations among left-handed men, who may be more susceptible to disruptive events during fetal development.
Researchers found that boys with autism exhibit higher levels of stereotyped behaviors and cognitive difficulties than girls, but these sex differences also appear in children without ASD. The study suggests naturally occurring sex differences in all children may contribute to the observed sex differences in autism.
A study by Christin L. Munsch found that economic dependency increases the likelihood of cheating for both men and women, with men more likely to cheat when not primary breadwinners. Women who are primary breadwinners are less likely to cheat as they increase their income share.
A new study by University of Maryland researchers reveals that the brain's 'gender' may be more flexible than previously thought. The study found that a specific enzyme plays a key role in masculinization, allowing certain genes to be 'unsilenced'. This process can even occur after the window for brain sexual differentiation has closed.
Researchers at McGill University found that men with short index fingers and long ring fingers are more agreeable and less quarrelsome with women. This unexpected phenomenon may be linked to fetal exposure to hormones during pregnancy.
A study in female mice reveals the brain region where hormonal state and social interaction are integrated, providing insights into human attraction and rejection behaviors. The researchers found that neurons dedicated to socio-sexual behavior were active only when females were receptive to males.
Researchers have found that ghrelin increases sexual activity and motivation in mice, suggesting a possible role for the hormone in regulating human sexuality. Further research is needed to understand the effects of ghrelin on humans, but ghrelin inhibitors may hold promise as new treatments for sex addiction.
A French study found that men are more likely to help women wearing high heels than those wearing flat shoes. The study suggests that men associate high heels with femininity and attractiveness. Men were also quicker to start chatting with women wearing heels, indicating a stronger instinct to be helpful.
A study published in Current Biology found that aggressive chimpanzee males sire more offspring, suggesting sexual coercion is an adaptive strategy for males. Genetic evidence showed that high-ranking males who intimidate females when they are not swollen had more reproductive success.
Researchers discovered that male nematode brains suppress food-seeking behavior to focus on finding a mate. This study sheds light on how subtle changes in brain circuitry dictate differences in behavior between males and females.
Researchers from Georgetown University's Institute for Reproductive Health developed strategies to change inequitable social norms resulting in gender-based violence. The study highlights the importance of community support, leaders, and positive social support in transforming gender roles.
A recent study found that men who viewed images of sexy women felt less connected to others and were less likely to make charitable contributions. Exposure to such images temporarily decreased male consumers' sense of psychological connectedness with others, making them less receptive to ads promoting social benefits.
Researchers found that teenage girls who skipped school or failed tests were more likely to engage in vaginal sex and less likely to use condoms. The study also showed a link between academic events and emotional experiences in romantic relationships.
A new study finds that children's sipping or tasting of alcohol is more closely related to perceived parental approval than psychosocial proneness for problem behavior. This suggests that early exposure to alcohol may not necessarily lead to later problem behaviors, but rather be a result of familial cultural norms.
A study by University of Washington sociologist Sarah Diefendorf found that young evangelical Christian men who pledged abstinence before marriage struggled with sexual temptation and confusion once married. The men reported feeling pressured to maintain control over sex and struggling to discuss it with their wives.
Research suggests that childhood abuse, sexual victimization, and prior suicidal behavior are significant risk factors for service members and veterans who attempt or commit suicide. The study found that soldiers who reported abuse as children were three to eight times more likely to report suicidal behavior.
Research shows that women with resilience are better equipped to handle sexually oppressive experiences, while those with low resilience may develop mental health problems. Psychologists can help clients learn to cope by assigning meaning to adversity and recognizing objectification as a flawed cultural practice.
Stowers researchers identified two classes of pheromone receptors that help male mice detect female presence and ovulation, essential for triggering the mating process. The findings provide new insight into how the mammalian brain processes sensory information like pheromones to elicit courtship behaviors.
In a study published in Current Biology, researchers found that the Abdominal-B gene controls a set of neurons responsible for a major part of female fly receptivity. This discovery provides insight into the neural circuitry that drives courtship behavior on the female side.
