Watching Violent Black Video Game Characters Increases Unconscious Bias in White Viewers
A recent experiment published in the International Journal of Psychology found that White participants who watched a Black character commit violent acts in a Grand Theft Auto V clip displayed heightened implicit racial bias, while their explicit attitudes remained unchanged. The same footage did not affect White participants' unconscious bias when the character was White, and Black participants showed no significant implicit shift but reported lower overt racism after viewing the Black character. The study isolated race as the sole variable by using identical video clips, and it employed both the Implicit Association Test and a self‑report scale to measure prejudice. Researchers argue that racial identity and media framing interact to shape subconscious attitudes.
Childhood Trauma Leaves a Lasting Mark on Biological Systems, Study Finds
A Portuguese cohort study of 13‑year‑olds found that exposure to adverse childhood experiences (ACEs) before age ten is linked to higher allostatic load in adolescence. Specific traumas such as parental separation or divorce showed a direct association, while the total...
Intrinsic Capacity Scores Predict the Risk of Mild Cognitive Impairment in Older Adults
A GeroScience study examined 731 UK adults aged 60‑89 and found that lower intrinsic capacity—a composite of physical, mental, sensory and vitality measures—significantly predicts the onset of mild cognitive impairment (MCI) over a 4‑5‑year period. Researchers used item response theory...
Laughter Plays a Unique Role in Building a Secure Father-Child Relationship, New Research Suggests
A recent study in the Journal of Experimental Child Psychology examined how mothers and fathers make preschoolers laugh and how those moments relate to attachment security. While both parents employed comparable physical and vocal play strategies and elicited equal amounts...
Ashwagandha Shows Promise as a Treatment for Depression in New Rat Study
Researchers at Mardin Artuklu University found that Ashwagandha alleviated depression-like behaviors in adolescent male rats subjected to chronic unpredictable stress. The herbal supplement not only improved pleasure and despair measures but also reduced brain inflammation and cell‑death markers more effectively...
Early Exposure to a High-Fat Diet Alters How the Adult Brain Reacts to Junk Food
A study in Nutritional Neuroscience shows that rats exposed to a high‑fat, high‑sugar (Western) diet during gestation and lactation retain metabolic imprints into adulthood. Even after months on a healthy diet, these animals exhibit elevated blood glucose and protein levels....
How Sexual Orientation Stereotypes Keep Men Out of Early Childhood Education
A new study of 334 U.S. men, split between gay and straight, reveals that both groups overestimate gay men’s interest in early childhood education, while straight men accurately gauge their own low interest. This pluralistic ignorance stems from sexual‑orientation stereotypes...
People with Social Anxiety Are Less Likely to Experience a Post-Sex Emotional Glow
A recent study published in Cognitive Behaviour Therapy compared 54 adults diagnosed with social anxiety disorder (SAD) to 54 peers without the condition. Both groups reported similar numbers of sexual encounters over a three‑week diary period, indicating that SAD does...
The Extreme Male Brain Theory of Autism Applies More Strongly to Females
A meta‑analysis of 34 studies involving 1.23 million participants found that autistic females exhibit markedly larger deviations in empathy and systemizing scores compared with neurotypical females than the analogous gaps observed in males. The empathy deficit in autistic women was three‑to‑five...
A Newly Discovered Brain Cluster Acts as an on and Off Switch for Sex Differences
Researchers identified a distinct neuronal cluster in the mouse medial amygdala, dubbed DIMPLE, that is permanently active in females but silent in adult virgin males. The cluster reactivates in males after a single mating event, driven by prolactin and sustained...
Researchers Identify Personality Traits that Predict Alcohol Relapse After Treatment
French researchers found that the personality trait of novelty‑seeking is the strongest predictor of alcohol relapse within three months after inpatient withdrawal. In a cohort of 76 patients, 29 relapsed and scored higher on novelty‑seeking and lower on harm avoidance,...
The Bystander Effect Applies to Virtual Agents, New Psychology Research Shows
A new study in Consciousness and Cognition shows that working alongside a virtual AI partner reduces people’s explicit sense of control while simultaneously boosting their unconscious sense of agency, measured via temporal binding. In two online experiments participants either acted...
Two to Three Cups of Coffee a Day May Protect Your Mental Health
A new analysis of 461,586 UK adults tracked for over 13 years found that drinking two to three cups of coffee daily is linked to the lowest risk of developing mood and stress disorders. The protective effect disappears at five...
Study Links Parents’ Perceived Financial Strain to Delayed Brain Development in Infants
A new PNAS study of 293 infants in Boston found that parents’ perception of insufficient household income is linked to slower neurodevelopmental trajectories measured by EEG. Infants in families reporting financial strain showed reduced rates of change in alpha peak...
New Analysis Shows Ideology, Not Science, Drove the Global Prohibition of Psychedelics
A new study in Contemporary Drug Problems traces the 1971 United Nations Psychotropic Substances Convention to political ideology, media sensationalism, and Cold‑War geopolitics rather than scientific evidence of harm. Archival analysis shows diplomats exaggerated health risks, linked psychedelics to youth...
Therapists Test an AI Dating Simulator to Help Chronically Single Men Practice Romantic Skills
Researchers at Université du Québec à Montréal piloted an AI‑driven dating simulator called Kindling with 32 chronically single men. Participants engaged in a three‑stage text chat with a virtual partner, Marie, and were debriefed by a therapist. Follow‑up surveys over...
Massive Global Study Links the Habit of Forgiving Others to Better Overall Well-Being
Researchers analyzed data from the Global Flourishing Study, covering 207,919 adults in 23 nations, to examine whether a dispositional tendency to forgive predicts later well‑being. Using two waves of surveys spaced a year apart, they found that higher forgivingness was...
Supportive Relationships Are Linked to Positive Personality Changes
An eight‑month longitudinal study of 1,403 university students found that perceived autonomy support from close others was associated with modest gains in subjective well‑being and slight increases in the Big Five traits of agreeableness, conscientiousness and openness. Participants who reported...
Brain-Controlled Assistive Robots Work Best when They Share the Workload with Users
A Frontiers in Human Neuroscience study examined three autonomy levels for brain‑robot interfaces in a virtual kitchen, ranging from Assisted Teleoperation to Full Automation. While Full Automation was fastest and required the least mental effort, users felt a loss of...
Eating Ultra-Processed Foods Is Not Linked to Faster Mental Decline, Study Finds
A ten‑year longitudinal study of 1,371 Dutch adults found that consuming ultra‑processed foods, which made up about 20% of daily diet weight, did not accelerate cognitive decline. Researchers used the NOVA classification to quantify processing levels and applied multiple cognitive...
Hypocrisy and Intolerance Drive Religious Doubt Among College Students
A new study published in *Psychology of Religion and Spirituality* surveyed 3,953 U.S. college students across private, public, and Christian campuses, revealing that perceived hypocrisy and LGBTQ intolerance are the top reasons for religious doubt. The research shows that doubt...
A Single Dose of DMT Reverses Depression-Like Symptoms in Mice by Repairing Brain Circuitry
Researchers at Uppsala University reported that a single 30 mg/kg injection of the psychedelic N,N‑dimethyltryptamine (DMT) reversed depression‑like behaviors in mice subjected to chronic stress. The treated animals recovered their preference for sweetened water, displayed improved working‑memory performance, and showed reduced...
Brain Scans Reveal Two Distinct Physical Subtypes of ADHD
A study published in General Psychiatry used structural MRI and machine‑learning clustering to reveal two distinct neuroanatomical subtypes of ADHD in 135 children and adolescents. Subtype A is characterized by increased gray‑matter volume in frontal regions and the cerebellum and is...
