Negative correlation between habenular volume and duration of gambling disorder
Brain network alterations in mobile phone use problem severity
How does CBT work on recovery from depression through positive affect route
Dissociable impacts of physical and psychological factors on side effects after Covid-19 vaccination in Japan
Physical characteristics and lifestyle habits linked with intact immune function enhanced side effects, whereas psychological characteristics linked with impaired immune function also enhanced side effects. These seemingly contradictory results could be explained at least partly by nocebo effects and suggest the need for psychological support for people with high levels of depressive symptoms or trait anxiety. Furthermore, interaction results imp…
Baccarat gamblers follow trends rather than adhere to the gambler's fallacy
This study investigated the cognitive biases underlying baccarat gambling behaviors through an analysis of 17,970,830 games played by 6625 customers in a casino. Baccarat, a popular high-stakes game in East Asia, involves predicting the outcome of two hands, where the results are inherently unpredictable, similar to the structure of games such as roulette. In contrast to existing theories predicting the emergence of the gambler's fallacy-or negat…
Ambivalent effects of highly estimated personal strengths on adaptive functioning and internalizing symptoms in non-clinical autistic females
Revisiting Emil Kraepelin’s eugenic arguments
It is widely recognized that Emil Kraepelin explicitly advocated for eugenic ideas in his academic works. Given the renewed interest in related concepts such as self-domestication and neo-Lamarckism in different contexts, this article revisits his eugenic arguments by scrutinizing a section of his seminal work, the 8th edition of his textbook published in 1909. Our analysis reveals that Kraepelin’s arguments consisted of multiple theories and ide…
National burden of gambling in Japan
The study highlighted the prevention paradox of gambling in Japan. While national gambling policies primarily focus on the prevention and intervention for high-risk gamblers, a more effective approach would involve minimizing GRH across the entire population
Epigenetic aging in Williams syndrome
BACKGROUND: Williams syndrome (WS) is a rare genetic disorder caused by a microdeletion at the 7q11.23 region and is characterized by diverse symptoms encompassing physical and cognitive features. WS was reported to be associated to altered DNA methylation (DNAm) patterns. However, due to the limited information from long-term studies, it remains unclear whether WS accelerates aging. Genome-wide DNAm profiles can serve as "epigenetic clocks" to h…
Mental Health Problems and Their Association With Internet Use in Medical Residents
Objectives: Mental health problems (MHP) among medical residents are often found in clinical settings, and it sometimes leads to professional lapses. Evidence suggests that excessive Internet use (IU) is associated with MHP. We investigated residents' MHP assessing depression, anxiety, and self-esteem and their association with IU in a longitudinal design. Methods: A total of 208 residents participated in the study. The General Health Questionnai…
Assessing the hierarchy of personal values among adolescents
INTRODUCTION: For assessing personal values, the rating scale method may not adequately reflect the hierarchical structure of personal values and tends to be influenced by response style bias. The paired comparison method is considered a promising alternative approach, because it engages comparative judgment and may reduce response style biases. The present study aimed to compare these two methods for assessing the hierarchy of personal values am…
Exaggerated envy and guilt measured by economic games in Japanese women with anorexia nervosa
Anorexia nervosa (AN) patients are assumed to express high levels of guilt and envy. Ultimatum game (UG) is a standard behavioral task that focuses on interpersonal behavior when splitting a sum of money between two players. UG studies consistently demonstrate that people tend to decrease their inequity in outcomes, one explanation being that economically irrational decision-making may partly arise from the emotions guilt and envy. We assumed tha…
Discrepancy between explicit judgement of agency and implicit feeling of agency
Paradise Lost
The neural reward circuit and cognitive distortion play an important role in addiction; however, the relationship between the two has not yet been addressed. In this article, we review recent findings on nicotine dependence and propose a novel hypothesis. Previous research using functional magnetic resonance imaging (fMRI) has shown that while activation of the reward circuit (ventral striatum) appears in response to tobacco-related rewards in ni…
