Transmission Follows Attention: A Quantitative Analysis of Directional Asymmetry in Crisis Apparition Reports
No full textQuantitative analysis of 674 crisis apparition cases from two Victorian datasets (Phantasms of the Living 1886, Census of Hallucinations 1894). After strict filtering for timestamp verification, parent-child cases show complete directional asymmetry: 10 cases of children perceiving dying parents, 0 cases of parents perceiving dying children (p=0.001). Raw data shows 5.9:1 ratio. We propose the Attention Model: transmission follows the dying person's habitual attention, not relationship category. In documented cases, 90% of perceivers match the dying person's attention target. The Andre anomaly (dying child perceived by 7 neighbors and a dog, but not his mother at the bedside) supports location-targeting over attachment-targeting. Distance shows no effect. Consciousness at death not required

The mental health consequences of the 2023 genocide in Gaza, Palestine: A scoping review
No full textBackground: Israel’s genocide in the Gaza Strip has killed 7.9% of the population, and thousands of Palestinians have faced myriad forms of violence and imminent threats to life, including physical injuries from ballistics, home demolitions, and torture. These highly traumatic conditions pose severe psychological threats to Palestinians and may have reverberating effects in neighboring Arab countries. This scoping review aimed to examine the direct and indirect mental health consequences of Israel’s genocidal assault on Gazans, Palestinian citizens outside of Gaza, and populations in neighboring Arab countries and also investigated processes of coping and resilience among Palestinians.
Methods: Following (PRISMA-ScR) guidelines, 42 articles, which were published after October 2023, were identified from five major search engines, including PubMed, Scopus, SpringerLink, Proquest, and Google Scholar. Studies investigated the psychological impacts of the 2023 genocide in Gaza, and their results were categorized into three groups: psychological impacts of wars, resilience, and coping strategies studies under war circumstances.
Results: Findings revealed devastating mental health effects due to the genocide, with Gazans experiencing the most extreme outcomes. Gazan samples reported alarmingly high prevalence rates of mental health symptoms, including depression (72.7-99.5%), anxiety (65.0-99.7%), and PTSD (63.4-83.5%), which were the highest among all examined groups. Resilience and coping resources among Palestinians included cognitive strategies, family and social support, and religion.
Conclusion: These findings highlight the large-scale psychological consequences of the 2023 Gazan genocide and underscores the urgent need for emergency mental health interventions in Palestine. Immediate action is necessary to prevent further psychological damage from the genocide and avert an irreversible humanitarian catastrophe
Fighting fire with fire: The role of physiological arousal in media-induced recovery
No full textMedia use is often a means of recovering from stress and mental fatigue, and prior work suggests that emotionally intense media content may paradoxically support recovery. We examined whether physiological arousal contributes to this effect. In a preregistered, double-blind laboratory experiment, participants (N = 366) received caffeine or placebo, completed a cognitively demanding attention task, and then either watched an emotionally engaging video (positive stand-up comedy, negative horror, or a neutral documentary) or waited for four minutes. Caffeine increased skin conductance level and subjective arousal and reduced mental fatigue relative to placebo. All video conditions also facilitated recovery, with the horror video producing the largest improvement. However, we found no evidence that physiological arousal and media-induced emotion interacted to enhance recovery beyond their separate effects. In contrast to excitation transfer accounts, heightened arousal neither strengthened affective responding nor improved recovery beyond the effects of media exposure alone
The National Couples’ Health and Time Stress Biology Study (NCHAT-BIO): Wave 1 Methodology Report and Wave 3 Preview
No full textObjective. Sexual minority populations are growing, experience elevated physical and mental health risks, and have unique stressor exposures. However, biopsychosocial research on sexual minority individuals at the population level remains limited. Addressing this gap, we launched the National Couples’ Health and Time Stress Biology Study (NCHAT-BIO), the first US-based study focused on stress biology within a large, diverse sample of married/cohabiting sexual minority and heterosexual adults. NCHAT-BIO capitalized on the unique opportunity of NCHAT, a population-representative US sample which intentionally oversampled sexual minority respondents.
Methods. NCHAT-BIO was approved by The Ohio State University and Gallup Institutional Review Boards. A total of 950 participants completed at-home dried blood spot (DBS) collection with return by mail. After exclusions, 787 respondent samples were assayed. Samples were analyzed for interleukin-6 (IL-6), C-reactive protein (CRP), and Epstein Barr Virus (EBV) antibodies. Final analytic samples were: IL-6 (n=452), CRP (n=663), EBV (n=647, including n=84 EBV negative). These biomarker data can be merged with rich NCHAT survey responses, time diaries with an embedded Experience Sampling Method (ESM) component, and contextual state- and county-level indicators.
Dissemination. Wave 1 NCHAT-BIO data have been deposited at ICPSR for public release; the current report should be cited in future empirical manuscripts using these data. Wave 1 NCHAT survey data are also at ICPSR, and the two archives will be linked to facilitate integrated use.
Future Directions. Whole blood data collection from Wave 3 NCHAT participants will begin in 2026. Planned assays, which will also become publicly available, include IL-6, CRP, and epigenetic aging (per DNA methylation)

A revisão será conduzida conforme as recomendações metodológicas do Joanna Briggs Institute (JBI) e orientada pelo checklist PRISMA-ScR. Os achados subsidiarão a construção de uma tecnologia educativa voltada à promoção do uso racional de medicamentos no âmbito do Sistema Único de Saúde
Deep conversations: asking informative questions to learn about others' personalities
No full textIn this project, we investigate how the questions people ask during conversation with a stranger shape what they learn about their partner's personality. We run two studies in which online participants are paired with a stranger and chat for 10 minutes. In both studies, participants complete the 44-item Big Five personality inventory (John & Srivastava, 1999) about themselves before the chat, and then complete the same inventory about their partner after the chat concludes. We manipulate questions provided during the chat to guide the conversation. We test whether "deep" questions judged to be informative (Brockbank et al., 2025) allow for more accurate predictions about a partner's personality than "small talk" questions or questions participants ask without any guidance
Social Identity Online: The Role of Group Salience on Prosocial Behavior
No full textA significant portion of all contemporary social interaction takes place online. While the destructive power of the social internet has been well-documented, there is a comparative dearth of research on the therapeutic potential of online social interaction. People are increasingly seeking and receiving support on the social internet. This study applied concepts from social identity theory to investigate whether the salience of a shared group identity influences online prosocial behavior
