In recent years, the possible benefits of mindfulness meditation have sparked much public and academic interest. Mindfulness emphasizes cultivating awareness of our immediate experience and has been associated with compassion, empathy, and various other prosocial traits. However, neurobiological evidence pertaining to the prosocial benefits of mindfulness in social settings is sparse. In this study, we investigate neural correlates of trait mindful awareness during naturalistic dyadic interactions, using both intra-brain and inter-brain measures. We used the Muse headset, a portable electroenc

A large body of research has documented that smoking behavior is associated with a number of psychological variables. Weiss, Mouttapa, Cen, Johnson, and Unger (2011) studied a culturally diverse sample of 1,771 adolescents who reported that the risk of smoking initiation was significantly higher among students who scored higher on hostility and depressive symptoms, and were bully-victims. Mykletun, Overland, Aaro, Liabo, and Stewart (2008) carried out a population-based health survey on 60,814 adults aged between 20 to 89 years and reported that anxiety and depression were the most common in c

Importance: Trauma-focused treatments are effective for posttraumatic stress disorder (PTSD) but are rarely offered to patients with comorbid substance use disorder. Research suggests gender-based differences in prevalence and treatment needs for these patients, but treatment trials have mainly included men. Objective: To evaluate whether integrated trauma-focused psychological treatment (ie, integrated treatment) leads to greater reduction in PTSD symptom severity and weekly alcohol use than usual treatment (ie, relapse prevention) for alcohol use disorder (AUD) in women. Design, Setting, and

In this clinical study on helping students prepare for an exam, we compared three different treatments. All students were asked to take a practice exam. One group was then given worked-out solutions for that exam, another group was given the solutions and targeted exercises to do as homework based on the result of their practice exam, and the third group was given the solutions, homework, and also an hour of one-on-one tutoring. Participants from all three conditions significantly outperformed the control group on the midterm exam. However, participants that had one-on-one tutoring did not out

Having a sense of meaning in life (MIL) has been acknowledged as a catalyst to psychological flourishing. As such, understanding ways to promote MIL represents a worthy goal for those interested in bolstering positive outcomes. This study sought to replicate the findings of Heintzelman, Trent & King (2013 Psychol. Sci. 24 , 991–998 ( doi:10.1177/0956797612465878 )), who found that MIL could be influenced by external stimulation. Their findings suggest that exposure to coherent stimuli produces significantly higher MIL scores than exposure to incoherent stimuli. Using materials and methodol

Abstract Theoretical models have been developed to understand how social class influences individual thoughts, feelings and behaviours. However, the validity of these models is threatened by the prevailing use of small, non-diverse samples and flexible measurement practices. We preregistered replications of 35 key hypotheses from 17 correlational and 5 experimental studies, and collected large, quota-based or probability samples from the USA, France, Switzerland and India ( N total = 33,536). Our analysis yielded three central findings: (1) ~50% of the effects were successfully replicated; (2)

Accumulating evidence suggests that the glutamatergic system plays a major role in the pathophysiology of obsessive compulsive disorder (OCD) and empathic processing. Particularly, genetic influence of glutamate transporter gene (SLC1A1) on OCD has been frequently replicated in previous studies, but several studies did not replicate the result. Therefore, we aimed to replicate the associations between the SLC1A1 and OCD in a Korean population. In addition, we investigated the influence of SLC1A1 on trait empathy, impairments in which are characteristic of OCD. Six single-nucleotide polymorphis

Major depressive disorder (MDD) is a leading cause of disability worldwide, yet many patients have inadequate responses to current treatments. Dimethyltryptamine (DMT), a serotonergic psychedelic with rapid onset and short duration, shows promise as a potential antidepressant (AD), although clinical evidence in MDD remains limited. We conducted a phase IIa, double-blind, placebo-controlled, randomized clinical trial to evaluate the efficacy and safety of intravenous DMT (SPL026; DMT fumarate) in adults with moderate-to-severe MDD. Participants received a single 21.5-mg dose of DMT or placebo i

Recent findings suggest a role of oxytocin on the tendency to spontaneously mimic the emotional facial expressions of others. Oxytocin-related increases of facial mimicry, however, seem to be dependent on contextual factors. Given previous literature showing that people preferentially mimic emotional expressions of individuals associated with high (vs. low) rewards, we examined whether the reward value of the mimicked agent is one factor influencing the oxytocin effects on facial mimicry. To test this hypothesis, 60 male adults received 24 IU of either intranasal oxytocin or placebo in a doubl

This study examines the mediating and moderating role of metacognitive awareness in the relationship between self-regulated learning and mathematics achievement of university students in Ghana. Although self-regulated learning has attracted attention as a predictor of academic performance, few studies have examined how metacognitive awareness interacts with self-regulated learning to influence mathematics achievement in the Ghanaian context. A quantitative cross-sectional design was employed. Data were collected from 315 university students, representing a population of 3,240, using a structur

Social media movements centered on body positivity and body neutrality both encourage healthy attitudes toward the physical body; however, these movements are conceptually distinct and may have unique influences on body image. This study examined how brief exposure to different types of body acceptance and weight-stigmatizing content affects body image and mood. Participants consisted of women and gender-diverse individuals (N = 326) who completed an online survey and were randomly assigned to view one of four TikTok video compilations: body neutrality, body positivity, weight-stigmatizing, or

BACKGROUND: When attempting to statistically distinguish between a null and an alternative hypothesis, many researchers in the life and social sciences turn to binned statistical analysis methods, or methods that are simply based on the moments of a distribution (such as the mean, and variance). These methods have the advantage of simplicity of implementation, and simplicity of explanation. However, when null and alternative hypotheses manifest themselves in subtle differences in patterns in the data, binned analysis methods may be insensitive to these differences, and researchers may erroneou

We conducted a close replication of the seminal work by Marcus and colleagues from 1999, which showed that after a brief auditory exposure phase, 7-month-old infants were able to learn and generalize a rule to novel syllables not previously present in the exposure phase. This work became the foundation for the theoretical framework by which we assume that infants are able to learn abstract representations and generalize linguistic rules. While some extensions on the original work have shown evidence of rule learning, the outcomes are mixed, and an exact replication of Marcus et al.'s study has

This study aimed at replicating a previously reported pattern: costly apologies are perceived as more sincere than non-costly apologies even when the transgression was unintentional, while costly apologies do not foster forgiveness more than non-costly apologies when the transgression was unintentional. We conducted a vignette study with a 2 (apology cost: costly vs. non-costly) × 3 (intention: no vs. ambiguous vs. malicious intention) between-participants factorial design. We failed to replicate the aforementioned pattern. Instead, we found that costly apologies promote not only perceived sin

Abstract Background Prior research shows that humans adjust their learning rate based on environmental volatility. This adaptation has been shown to be reduced in individuals with high levels of anxious-depression, but past studies have been cross-sectional, making it unclear whether this adaptation is trait-like or responsive to treatment. There are also questions about the basic replicability of this effect with recent studies failing to find robust associations. Method In the Precision in Psychiatry study, we examined changes in learning rate adaptation in a points-loss task, following four
