Lifelong singles score lower on life satisfaction and show distinct personality traits compared to those in long-term relationships. Using data from 77,000 Europeans aged 50+, researchers observed that lifelong singles are less extroverted, conscientious, and open to new experiences. While single women report higher satisfaction than single men, societal expectations about marriage further impact satisfaction levels in cultures with high marriage rates.
A new study suggests complex beliefs like paranoia may have roots in visual misperception. Participants prone to paranoia or teleological thinking were more likely to wrongly identify one moving dot as chasing another in a visual task.
A new study reveals that a reduced neural response to rewards in teens predicts the first onset of depression, but not anxiety or suicidality. Researchers used EEG scans to measure "reward positivity" in at-risk adolescents and found that those with blunted responses were more likely to develop depression.
Researchers have found that ketamine’s antidepressant effects target astroglia, a type of brain support cell, rather than neurons, challenging conventional views. Using zebrafish, scientists observed that ketamine suppressed the “giving up” behavior caused by futility signals, an effect linked to astroglial activation.
Large language models (LLMs) can identify when they are being given personality tests and adjust their responses to appear more socially desirable. Researchers found that LLMs, like GPT-4, showed exaggerated traits such as reduced neuroticism and increased extraversion when asked multiple test questions.
A new study shows that knowing you're under surveillance triggers a faster, automatic brain response to detect faces and gaze direction. Researchers found that participants monitored via CCTV became hyper-aware of facial stimuli nearly a second faster than those not being watched, even without realizing it.
A new study reveals that developmental differences strongly influence dominance roles in twin relationships, with typically developing twins perceived as dominant over their nontypically developing siblings. This dominance imbalance persists throughout childhood, even if developmental challenges improve.
Archaeologists studying the Charterhouse Warren site in England found evidence of a massacre, where at least 37 individuals were butchered, likely partly consumed, and dehumanized by their enemies. Analysis of over 3,000 bone fragments revealed blunt force trauma and cut marks, indicating intentional violence rather than ritualistic funerary practices.
New research links a positive attitude, or "growth mindset," to higher levels of passion and determination. A study of over 1,500 participants aged 13 to 77 found that those with the most positive outlook had significantly greater willpower and enthusiasm than those with a negative mindset.

These research articles involve depression, seasonal affective disorders, grief, pain, sadness, happiness and generally news regarding mental health research.

A new study analyzing genetic data from over 300,000 people revealed that women with a high genetic risk for depression also face a higher likelihood of developing heart disease, even without a depression diagnosis. This link was not observed in men, highlighting significant gender differences. Researchers emphasized the importance of addressing cardiovascular health in women, particularly those with depression, regardless of menopausal status.
Men who strongly adhere to traditional masculine ideologies, such as suppressing emotions and valuing independence, are more than twice as likely to attempt suicide compared to those with more egalitarian views. The study identified three groups of men—Egalitarians, Players, and Stoics—with Stoics being at the highest risk due to their attitudes and behaviors, especially during mental health crises.
Depression may increase the risk of menstrual pain, or dysmenorrhea, through mechanisms such as sleep disturbances. Using genetic analysis, researchers found that depression likely causes period pain, rather than the reverse, highlighting an underexplored connection between mental and reproductive health. The study suggests that addressing sleep issues and mental health could improve treatment for severe menstrual pain.

Schizophrenia News

Research news involving schizotypal personality, anxiety, paranoia, unconventional thoughts and beliefs is covered.

A new study has identified a distinct brain network connecting areas of atrophy associated with schizophrenia, offering a unified view of its neuroanatomy. By analyzing data from over 90 studies and more than 8,000 participants, researchers created an atrophy connectivity map that overlaps with regions linked to schizophrenia, such as the insula and hippocampus.
A new study reveals how genetic deficits, particularly in the Tbx1 gene, are linked to reduced brain volume and altered social behavior, findings relevant to autism and schizophrenia. Researchers observed smaller amygdala volumes in Tbx1-deficient mice, a brain region key to emotional regulation and social behavior. These mice displayed less interest in social interaction, relying more on non-social cues like bedding preferences.
