Researchers found no correlation between self-reported relationship satisfaction and sexual frequency, but automatic behavioral responses revealed a positive link between the two. Studies showed that couples who had sex more frequently were more likely to associate their partners with positive attributes.
A special collection examines the evolution and function of play using computational and mathematical models. The research reveals insights into factors predicting play dynamics, occurrence, and trajectory in animals.
New research from Aarhus University found that conservative voters prefer strong leaders with deep voices, while liberal voters prefer more gentle features. This study challenges the idea that voters carefully weigh pros and cons when making decisions.
Researchers studying ancient neural circuits in humans have found that vestigial muscles behind the ears are still responsive to sounds that attract attention. This discovery could lead to new insights into infant hearing deficits and the development of objective measures for positive emotions in adults.
A Norwegian study found that men are most jealous of sexual infidelity, while women are more jealous of emotional infidelity. This difference may be due to evolutionary psychology factors, such as paternity insecurity and the need for men to invest resources in their children.
A recent study found that sex differences in mate preferences are much larger than previously appreciated and stable across cultures. Men generally favor younger, physically attractive mates, while women seek older, financially secure partners. These findings highlight the significant role of gender in shaping human mating behavior.
A Dartmouth College study reveals that male tree crickets expend the same amount of energy per unit mass while singing, contradicting previous theories on biological trade-offs. The researchers found that faster pulse rates and longer song characteristics do not result in greater calorie burn.
Researchers found that men donate four times more to an attractive female fundraiser in response to another male's contribution, suggesting a subconscious competitive helping behavior. To improve fundraising success, seed campaigns with larger donations early and make fundraisers smile.
A study found that men are attracted to women with a specific angle of lumbar curvature, which would have supported pregnant women during childbirth. This preference has evolutionary roots and is not related to buttock size.
A Duke University study found that chimpanzees and bonobos prefer the glass half full when presented with a choice between two snacks. The apes were more likely to choose fruit over nuts when framed as a prize rather than a penalty, regardless of equal average payoffs.
A recent study at the Norwegian University of Science and Technology found that both men and women tend to misinterpret each other's social signals. Women reported being misinterpreted as sexually interested approximately 3.5 times a year, while men reported being misinterpreted less often. The results suggest that these miscommunicati...
A study found that two-year-old children conform to the behavior of their peers more often than great apes. Children conformed more than half the time, while chimpanzees and orangutans stuck to their learned strategy.
A study of over 12,000 Finns found that women generally prefer same-aged or slightly older male partners, while men tend to be interested in women in their mid-20s due to fertility. This evolutionary difference may reflect women's greater control over mating choices and the resulting selection pressures.
The 'anger face' is a cross-culturally universal facial expression that employs seven distinct muscle groups to signal the emotional state of anger. Researchers found that each component of the face makes an individual appear physically stronger, suggesting it evolved as a threat display to intimidate others.
Research published in Psychological Science found that procrastination and impulsivity are genetically linked, with a complete genetic overlap between the two traits. This suggests that procrastination may be an evolutionary byproduct of impulsivity, manifesting itself more in modern times.
A study by University of Maryland researchers predicts that strong social ties and low mobility enable the evolution of third-party punishment. In contexts with high social constraint, responsible punishers can induce cooperation and benefit the community.
Researchers found a stark contrast in sexual regret between men and women, with women more likely to regret casual sex due to potential reproductive costs. The study suggests that regret can play a functional role in guiding adaptive sexual decisions.
Women prefer low-pitched voices, even if they're perceived as cheats, to attract men for brief, short-term relationships. Researchers at McMaster University discovered that masculine voices are linked to an increased likelihood of infidelity in long-term partnerships.
A recent study suggests that men's stronger sexual impulses are a key factor in their higher rates of infidelity. Men experienced stronger impulses to pursue attractive partners, regardless of whether it was considered 'good' or 'bad', whereas women were more likely to exert self-control and resist these temptations.
A team of Penn biologists offers a mathematically based explanation for why cooperation and generosity have evolved in nature. Generous strategies, which involve cooperating with opponents but also forgiving defectors, are shown to be the only approaches that resist defectors over the long term.
According to Concordia University professor Gad Saad, the drive to consume is rooted in a shared biological heritage. He found that four key Darwinian factors - survival, reproduction, kin selection, and reciprocal altruism - shape narratives in consumer products like movies and song lyrics.
Researchers found that ape and human infant gestures shared common forms and functions, including reaching, pointing, and raising arms. The study's findings suggest that humans inherited a language of gestures from our last common ancestor with chimpanzees and bonobos.
A study published in Human Nature found that rural Indonesian Karo Batak people prefer women with big feet, challenging the one-size-fits-all theory of attractiveness. This cultural preference is linked to their ecological context and limited exposure to Western media.
A Northwestern University study reveals that facial preferences differ among populations, with distinct chin shapes found across various groups. The findings suggest that human mate choices are influenced by factors beyond physical attractiveness.
Researchers dispute evolutionary psychology's 'adaptive' explanation for males' superior spatial navigation, suggesting it may be a result of testosterone levels. The study analyzed 35 species and found no consistent support for the hypothesis that male superiority is an adaptation.
Research finds bonobos voluntarily share food and forego meals for social interaction with strangers, highlighting evolutionary roots of human generosity. The study reveals that bonobos' behavior is driven by unselfish motivations and has limits when no social interaction is possible.
Researchers at UCSB's Center for Evolutionary Psychology report new findings on human behaviors, supporting the individual cooperation account over group cooperation theory. The studies involved structured social interactions with over 200 participants, who showed a preference for trusting individuals likely to cooperate, not those who...
Researchers Marcel Zentner and Klaudia Mitura found that nations with higher gender parity have fewer differences between men and women's preferences when choosing mates. The study, published in Psychological Science, suggests that evolution is only part of the answer to understanding mate choice.
A new study by the American Psychological Association found that 3-year-olds can evaluate the reasonableness of another person's distressed reaction and respond accordingly. The children showed concern for adults in situations involving real harm or injustice but not in cases where distress was unjustified.
Researchers found that victory poses signal feelings of triumph immediately after a win, challenging previous research on pride. Triumph expressions are automatic and universal across cultures, occurring on average 4 seconds after the end of a judo match.
A groundbreaking study in evolutionary analysis in law reveals that chimpanzees, like humans, show the endowment effect, with behavior influenced by an object's immediate situational usefulness. The research provides evidence that this psychological trait likely evolved prior to the human split from other species.
A study by Aaron Sell explores how fighting ability drives men's behavior and attitudes, including political orientation. Physically strong men are more likely to support the Republican position on foreign policy.
A study found that people primed with feelings of love for their partner behaved more aggressively towards attractive rivals. Meanwhile, researchers discovered that men who confess love first tend to feel happier than women in the long run.
A new study found that men who are more attractive tend to overestimate women's interest in casual sex, while women underestimate men's desire. This misperception may have evolved as a strategy for increased reproductive success.
A study by Michigan State University researchers found that 90% of participants would reroute a runaway boxcar onto tracks with only one person, overriding the moral rule not to kill. The experiment explored how people come to their moral judgments and whether behavior follows suit.
A new study published in Psychological Science found that vaccination and hand washing can reduce bias against stigmatized groups, including immigrants and the obese. The researchers conducted three experiments, which showed that people who felt secure through these measures exhibited less prejudice towards out-groups.
Researchers found that Yucatec Maya speakers and German speakers performed similarly when identifying mixed-emotion faces. The study suggests that emotions have evolved as basic human mechanisms, unaffected by language. This discovery challenges the idea that language plays a crucial role in understanding emotions.
Researchers find that people's economic decisions change when survival or reproduction is on their minds. This contradicts the idea of humans making rational choices in finance, suggesting biases developed millions of years ago still affect us today. The study suggests these ancient biases can profoundly alter financial decisions over ...
A new study published in Social Science Quarterly suggests that a preference for physically formidable leaders may have evolved to ensure survival in ancient human history. The research found a statistically significant association between height and perceived leadership capability and interest in running for office.
David Sloan Wilson's book applies evolutionary theory to urban planning, using natural phenomena like wasps and crows to understand human behavior. He creates a map of Binghamton neighborhoods reflecting civic engagement, providing insights into how cities define us.
A new framework for the evolutionary analysis of the mind proposes that humans cannot be accurately portrayed as being adapted only to a Stone Age environment due to recent selection of genes. Experimental evidence suggests that humans utilize general learning rules rather than a modular account of cognition.
A study of male rhesus macaques found that they steer clear of red-clad humans and steal food from the other tray, indicating an aversion to red. The researchers believe this reflects an evolutionary adaptation reflecting our species' social nature.
Researchers found that readers who identify with fictional communities develop psychological affiliation, similar to real-life group affiliations. The study suggests that reading fulfills a deep psychological need for belonging.
A new study led by Yale researchers found that monkeys treat individuals from outside their groups with suspicion, similar to human behavior. The findings suggest that the roots of human intergroup conflict may be evolutionarily quite ancient, dating back at least 25 million years.
The modern understanding of homosexuality originated in 19th-century Germany with the Imperial Criminal Code's anti-sodomy law, sparking public inquiry into same-sex eroticism. This led to key components of modern gay rights, including recognizing same-sex attraction as a fundamental aspect of individual biology or psychology.
A recent study from the University of Texas at Austin found that men are more than twice as likely to continue dating a girlfriend who has cheated on them with another woman. In contrast, women show the opposite pattern and are more likely to stay in relationships following a man's infidelity. The researchers suggest that this disparit...
A new study reveals that women decrease interactions with male relatives, including fathers, when they are most fertile. This behavior is believed to protect against inbreeding and the negative consequences associated with it. Women tend to call their mothers more frequently during high fertility days.
A recent study found that girls who experienced an insecure attachment to their mother at a young age tend to develop earlier and have their first period sooner. This is because an unstable environment can lead to accelerated pubertal maturation as an evolutionary adaptation to increase reproductive chances.
Researchers at Arizona State University update Maslow's pyramid to reflect new findings on evolutionarily fundamental motives. The revamped pyramid places parenting atop the hierarchy, alongside mate acquisition and mate retention, shifting away from self-actualization as a top need.
Researchers discovered that volunteers could rapidly assess whether a face was looking at them if it had exaggerated masculine or feminine features. Women were quicker to classify gaze direction when viewing more masculine faces, while men were faster with feminine faces.
A new theory suggests that higher intelligence is associated with novel social values and preferences in human evolution. More intelligent individuals are more likely to adopt liberal political ideology, atheism, and preference for sexual exclusivity. However, intelligence does not correlate with evolutionarily old preferences and values.
Researchers found that fa'afafine men in Samoa exhibit stronger kin selection, allocating resources to their nieces and nephews, potentially enhancing their own evolutionary prospects. This supports the kin selection hypothesis as a potential explanation for the persistence of male same-sex attraction.
A new study suggests that sex differences in jealousy are rooted in individual personality traits rather than evolutionary origins. Men with a dismissing attachment style tend to be more upset by sexual infidelity, while securely attached individuals find emotional betrayal more distressing.
A University of Missouri researcher recommends increasing repetition learning and reducing 'fun' activities in US schools to help bridge the gap between natural human learning abilities and modern knowledge needs. This approach can improve students' performance in subjects like science and math.
A recent study suggests that emotions play a crucial role in shaping consumer preferences, leading to greater consistency in choice-making. The researchers found that relying on feelings rather than cognitive thinking results in more consistent and long-term happiness.
A new study by Michigan State psychologist Carlos David Navarrete found that men's fears are reserved for members of their own gender when it comes to out-groups. The findings suggest that this fear is linked to evolutionary history, with male faces being a potent cue for danger.
A new study suggests that having an imperfect body may come with benefits for some women, as hormones redistribute fat from the hips to the waist. This redistribution is associated with increased strength and competitiveness, but not necessarily lower fertility or chronic disease rates.
Chimpanzee females employ copulation calls strategically to minimize social competition, particularly with other females. This behavioral adaptation allows them to secure the protective support of high-ranking males, thereby reducing risks associated with female-female competition.
A recent study found that maternal grandparents were more likely to maintain daily or weekly contact with their grandchildren than paternal grandparents. The research suggests psychological mechanisms rooted in evolutionary history, where women are always related by maternity, making family ties through the mother more significant.
The study reveals that 1- and 3-year-old children, as well as great apes, prefer a place-based strategy to remember hidden items, while humans reassess this preference with age. This suggests that some evolved cognitive strategies are masked early on in human development.
