By transferring vasopressin receptor genes into meadow voles, scientists observed a strong preference for current partners, mirroring the behavior of prairie voles. This study provides evidence that changes in a single gene can profoundly impact social behavior in animals.
Researchers suggest that male vulnerability to disease may drive female-biased societies and behaviors, such as division of labor. This 'sick-male' theory proposes that males are less resistant to infection due to genetic limitations, leading to social isolation and reduced exposure to disease.
A study found that childhood conduct problems predict depression, violence, and social phobia in young adults. Early conduct problems were a strong predictor of later violence, with children three and a half times more likely to engage in violent behavior.
Researchers found that the mushroom bodies of wasps progressively increased in size as they took on new tasks, such as working outside the nest. This suggests that the brain structure plays a crucial role in regulating social behavior and adapting to complex environments.
A study found that parents' attitudes towards social anxiety disorder treatment can significantly impact their children's benefits from therapy. Parents who had used medication or counseling in the past were more favorable towards these treatments, and those with a history of emotional problems preferred counseling.
A recent study found that women widowed less than a year experience more mental and physical problems compared to those who were married or widowed for longer. However, these women's mental health improved over time with social support.
Women in marriages with high relationship satisfaction show lower levels of cardiovascular risk factors, including blood pressure, cholesterol levels, and body mass index. High marital satisfaction also promotes healthy behaviors and protects against social isolation.
The University of Pittsburgh has received two grants to investigate an experimental device that aims to improve the quality of organs from brain-dead donors. The study, led by Dr. John A. Kellum and Dr. Michael DeVita, will evaluate the effectiveness of CytoSorb in reducing cytokines that compromise organ function.
Research suggests that early hominids lived in a more cooperative society than previously thought, with minimal sexual dimorphism and cooperating male behaviors. This challenges the idea of fierce competition among primates and instead reveals a social structure similar to modern humans and chimpanzees.
A new study by Cincinnati Children's Hospital Medical Center found that frequent school changes are an independent predictor of behavioral problems in children. The study involved 3,285 children between the ages of 5 and 14, who were more likely to experience behavioral issues if they attended multiple schools.
A study by Rebecca E. Lee and Abby C. King found that exercise programs can increase physical activity in sedentary older adults. The researchers reported a significant increase in physical activity among women who enrolled in an exercise-focused program compared to those in a nutrition-focused program.
A study by Yale researchers found that women do smile more than men, but the difference is modest and influenced by factors such as culture, ethnicity, age, and social role. When men and women think no one is looking, they smile similarly, and the sex differences disappear when they are in the same position of power or occupation.
A low-intensity behavioral and social skill program showed promise in reducing ADHD symptoms in children and improving parent-child relationships. The study found that parents who participated in the class reported fewer ADHD symptoms in their children and more consistent discipline practices, while teachers saw no significant difference.
The Field Museum researchers found that Tsavo lions were not 'aberrant' and did not kill humans due to damaged teeth. Instead, they engaged in a social tradition of man-eating, which was learned through generations and passed on to offspring.
Researchers discover evidence of culturally transmitted behaviors in orangutans, dating back 14 million years. The findings push back the origins of cultural transmission in apes, suggesting a stronger link to human culture.
Researchers found that parents of children with congenital heart defects can cope with their child's illness and may even experience lower levels of stress and fewer behavioral problems. The study suggests that social support may be a key factor in alleviating stress and reducing behavior issues.
Recent research suggests that prenatal cocaine exposure does not necessarily lead to developmental delay or behavioral problems in children. In a study of 163 children, assessors incorrectly labeled many as cocaine-exposed, perpetuating stereotypes and stigma, which can undermine cognitive and behavioral development.
A study found that African American parents of young children prioritize racial pride and self-esteem over promoting mistrust or bias. Home environments rich in Afrocentric culture positively impact cognitive development. Racial socialization is a key component of parenting, influencing child outcomes.
A study by Seth C. Kalichman found that HIV-positive men who were sensation seekers were more likely to have unprotected sex, regardless of alcohol use. Alcohol also predicted unsafe sex, independent of sensation seeking. The study suggests cognitive approaches can help improve risk reduction interventions for HIV-positive men.
Research suggests that altruism, not panic, drives human behavior during disasters. In emergency situations, people prioritize helping others over self-preservation. Clarke's study highlights the importance of community expectations and trust in authorities to guide behavior during crises.
Researchers at San Francisco State University found that 74% of women wearing perfume with a synthetic pheromone experienced an increase in sociosexual behaviors, including kissing, affection, and sexual intercourse. The study concluded that the pheromone increased the attractiveness of women to men, leading to more romantic behavior.
A new study found that brain-injured children from less stressed and more supportive families had significantly higher achievement and behavior scores than their peers. The authors speculate that severe traumatic brain injury exacerbates the effects of unfavorable family circumstances, leading to worse academic and behavioral outcomes.
Researchers have discovered that male orangutans engage in homosexual behavior in the wild, a phenomenon previously only observed among captive animals. This finding highlights the complexity of primate social behavior and challenges existing assumptions about great ape sexuality.
Researchers in London have found that high levels of neighborhood problems such as noise, unsafe areas, smells, fumes, and litter contribute significantly to levels of daily stress. These chronic stressors in urban neighborhoods can have important health effects, particularly for those living in lower socioeconomic status communities.
A single gene is responsible for the social behavior of roundworms, which may hold clues to understanding human social behaviors. The gene variation affects how nematodes respond to environmental stimuli and recognize pheromones.
