A new study from an international team of researchers found that an imbalance of the sexes leads to single parenting in birds. The researchers discovered that when there are more males than females or vice versa, the parenting roles shift, leaving the males to care for the chicks.
Young children tattle even when blameless, as a way to enforce social norms and cooperate with others. Research suggests that tattling can be seen as evidence of children recognizing important norms and caring about their importance.
Families with elevated psychosocial risks, including parent mental health issues and child behavior problems, are more likely to drop out of weight management treatment. Psychosocial screening early in treatment may improve outcomes for children with obesity.
Research finds that young adults' own financial behaviors have the most impact on their well-being, followed by their romantic partners' behaviors. Parents' financial expectations had the least impact, but still influence young adults' objective financial knowledge. The study suggests that even in non-marital relationships, a partner's...
Research from Bar-Ilan University suggests that excessive focus on self-control can lead to inflexible behavioral patterns, over-emphasis on norm-adherence, and strict rational thinking. This can result in problems with information processing, decision-making, and social behavior.
A study by the University of Toronto Rotman School of Management found that low confidence can lead to selfish behavior, but also increased generosity when public choices are made. In contrast, high confidence participants tend to be more generous in their choices.
Researchers found that a combination of teaching parents how to manage behavior and relationship-building strategies was more effective than just behavior-management strategies for reducing severe disruptive behavior. For children who haven't developed severe behavioral issues, only behavior-management strategies were beneficial.
A new study from the University of Portsmouth found that people who are more image conscious tend to support more crowdfunding campaigns. The research also showed that funders with public profiles containing photos engage in significantly greater levels of visible funding activity.
Researchers exposed rhesus macaques to sevoflurane three times during infancy and found increased behaviors such as self-touching and self-grooming at one and two years of age. These subtle changes persist even after the animals are no longer under stress, suggesting a long-term impact on anxiety levels.

A new study finds that nostalgia for America's past can buffer collective guilt and create group coherence. Those who glorify the US tend to be more nostalgic, which alleviates feelings of guilt about historical wrongs.
Barbara Dosher, UCI Distinguished Professor, receives the Atkinson Prize for her work on human memory, attention, and learning, while Etel Solingen is awarded the William & Katherine Estes Award for trailblazing research on nuclear proliferation.
A new model investigates how human behavioral changes evolve in response to extreme climate events and affect global temperature change. Long-term, less easily reversed behavioral changes have the most significant impact in mitigating greenhouse gas emissions and reducing climate change.
A social dilemma experiment found that punishment is ineffective in promoting cooperation among players, with players instead replacing defection with punishment. The study suggests that punishment has a demoralizing effect and reduces the incentive to choose cooperation over competition.
Researchers at USC found that automated Twitter accounts promoting the idea that e-cigarettes help people stop smoking are more likely to be hazardous to users' health. These 'social bots' were two times more likely than humans to promote both new products and the idea that e-cigarettes empower people to quit smoking.
Research on rhesus macaques suggests that some individuals are more likely to remain socially isolated due to a combination of genetic predisposition and environmental influences. This phenomenon is linked to reduced life expectancy in various species, including humans, who are experiencing an increasing epidemic of social isolation.
A study by Georgia State University found that black parents reported significantly fewer concerns related to autism symptoms than white parents. This disparity may affect healthcare providers' abilities to identify children who need further screening or evaluation, potentially leading to missed or delayed diagnoses in black children.
Researchers found that new immigrants initially provide little information to help the group but become fully integrated and valued members within five months. They suggest that an integration period is necessary before the benefits of an increased group size can be realized.
