Women are more likely to engage in aggressive behaviors toward peers with larger breast sizes, a recent study finds, highlighting how physical traits influence intrasexual competition.

A study reveals that chronic stress alters sperm's long noncoding RNAs, affecting offspring development and behavior, potentially leading to anxiety and depression-like symptoms, highlighting the role of paternal stress in epigenetic inheritance.

A recent psychology paper suggests that trypophobia, the fear of clusters of small holes, may have evolutionary origins linked to avoiding dangerous animals and infectious diseases.

A study found that cultural and ecological factors significantly influence odor pleasantness, with familiarity being the strongest predictor of pleasantness across diverse cultural groups.

Women with smaller breasts produce breast milk with higher lactose concentration, suggesting a hormonal link. This surprising finding highlights that breast size influences milk composition, though not its quantity.

A recent analysis reevaluates findings on evolutionary psychology, revealing it is growing comparably to the Standard Social Science Model (SSSM). Refined metrics suggest both paradigms are expanding in tandem, challenging previous claims of evolutionary psychology's decline.

While evolutionary psychology has grown, a new paper argues it hasn't surpassed the socio-cultural approach in prominence, challenging claims of a revolutionary paradigm shift in psychology.

Women rated taller men with larger shoulder-to-hip ratios as more attractive, masculine, dominant, and capable in fights. Self-perceived attractiveness influenced these preferences.

When resources are scarce, women prefer men with more feminine facial features, suggesting a shift in attraction towards potential providers, according to a recent psychology study.

Women find men more attractive when they interact with children, highlighting that caregiving behavior significantly boosts men's appeal.

New research suggests maternal grandmothers can significantly reduce emotional and behavioral problems in grandchildren who face multiple early life adversities.

In a recent paper published in the Archives of Sexual Behavior, researchers apply an evolutionary psychological framework to better understand the motivations and origins behind BDSM practices.

A recent evolutionary psychology study found that women preferred slightly feminine men for long-term relationships and rated them as better fathers, while still finding them equally attractive for short-term relationships.

While people still stereotype leaders as male, they slightly prefer female leaders, especially those with prestigious traits over dominant ones. This challenges the belief that male leaders are more favored and suggests a shift towards gender neutrality in leadership preferences.

Male dance groups are perceived as having higher coalition quality—greater effectiveness, formidability, and social bonding—compared to female groups, regardless of movement synchronization.
