A New Study Explores the Boundary Between Everyday Caffeine and Panic
A double‑blind crossover trial found that a moderate 150 mg dose of caffeine—roughly one and a half cups of coffee—does not increase self‑reported anxiety in adults with panic disorder or in healthy controls. While caffeine raised physiological arousal, measured by skin conductance, it also heightened costly avoidance behavior in both groups. Only one panic attack occurred during the study, suggesting that typical coffee servings are unlikely to trigger attacks. The findings challenge the blanket recommendation for panic‑disorder patients to avoid all caffeine.
Even Light Drinking Combined with Aging Is Linked to Reduced Brain Blood Flow and Thinner Tissue
A Stanford‑led study published in *Alcohol* found that even low‑level alcohol consumption, when combined with aging, is associated with reduced cerebral blood flow and thinner cortical tissue. Researchers examined 45 healthy adults (22‑70 years) and measured lifetime drinking patterns, brain...
Female Leaders Command Equal Obedience in a Modern Replication of the Milgram Experiment
Researchers replicated Milgram’s obedience experiment with 80 Polish volunteers in a lab and 800 participants in an online survey, testing whether a male or female authority figure changes compliance. The study found 88% obeyed a female professor and 90% obeyed...
Neuroscientists Identify Brain Regions that Drive Curiosity for What Might Have Been
Neuroscientists have shown that the brain's reward circuitry, especially the striatum, fuels a strong urge to learn what could have happened, even when that knowledge causes regret. In a functional MRI study, participants chose to view the hidden limit of...
The Age You Start Regularly Watching Adult Content Predicts Your Future Mental Health
Researchers analyzed 1,316 U.S. adults to map when they first encountered sexually explicit material and when they began viewing it regularly. They identified three trajectories—Early Engagers (first exposure ~14, regular use by 18), Casual Engagers (first exposure ~28, regular use...
Women Perceive AI as Riskier than Men Do, Study Finds
A new PNAS Nexus study of 3,049 U.S. and Canadian adults finds women consistently view artificial intelligence as riskier than men. The gap is linked to higher risk aversion among women and greater exposure to AI‑related job displacement. In an...
Do We Drink because We Feel Down, or Feel Down because We Drink? A New Study Has the Answer
A longitudinal study of 816 German adults published in the Journal of Affective Disorders found that better emotional well‑being reliably predicts lower alcohol consumption over time. Researchers used four measurement points across a year and applied latent change score modeling,...
Everyday Infections, Not Vaccines, Are Linked to an Increased Risk of Childhood Stroke
A population‑based study of 571 childhood strokes in Victoria, Australia (2017‑2023) found an incidence of 5.8 per 100,000 children, with a 42% rise over the period. Children who had a documented infection within the prior 60 days were more than...
Smarter Men Possess More Masculine Body Shapes but Report Fewer Casual Sex Partners
A new study in Evolutionary Psychological Science finds that higher fluid intelligence in young men correlates with stronger grip strength and a more V‑shaped shoulder‑to‑hip ratio, suggesting a link between cognition and physical fitness. The same men reported fewer casual...
Precommitment Can Lead to Healthier Food Choices Under Stress, Study Finds
A recent Psychoneuroendocrinology study shows that stress drives psychology students to favor tastier, less‑healthy foods, but a precommitment step—removing the unhealthy option in advance—significantly raises the share of healthy selections. Participants chose the healthier item in only 21% of unrestricted...
Childhood Adversity Predicts Combined Physical and Mental Illness in Later Life
Researchers analyzing data from over 4,000 Chinese adults aged 45 and older found that cumulative childhood adversity markedly increases the likelihood of developing both depression and chronic physical disease later in life. Participants reporting four or more adverse childhood experiences...
New Psychology Research Shows People Consistently Underestimate How Often Things Go Wrong Across Society
A new study published in the Journal of Personality & Social Psychology reveals a pervasive "failure gap"—people consistently underestimate how often negative events occur across society. An extensive research program involving about 3,000 participants, real‑world data, and field experiments showed...
Short Video Addiction Is Linked to Lower Life Satisfaction Through Loneliness and Anxiety
Researchers from Trakya University found that problematic use of short‑form video apps triggers a chain of psychological effects that erode life satisfaction. In a two‑wave study of 234 university students, higher short‑video addiction at the start predicted greater loneliness three...
Unrestricted Generative AI Harms High School Math Learning by Acting as a Crutch
A randomized trial at a Turkish high school found that unrestricted access to generative AI (GPT Base) dramatically improved students' practice scores but caused a 17% drop in unassisted exam performance. A guided version (GPT Tutor) that forced step‑by‑step hints...
Lifting Weights Builds a Sharper Mind and Reduces Anxiety in Older Women
A three‑month randomized trial found that older women who engaged in resistance training—whether using heavier weights for eight to twelve reps or lighter weights for ten to fifteen reps—experienced significant gains in cognitive performance and marked reductions in depression and...
