Summary: Ageing is associated with excessive brain iron, which may lead to cognitive deficits. Lack of dopamine may contribute to the increase of iron with advancing age. This study found that individuals with low dopamine levels are more likely to accumulate iron, resulting in detrimental changes in working memory. Understanding the role of dopamine in modulating iron accumulation across the human lifespan is important for future research.

Summary: The study used meta-analysis to demonstrate a significant association between COMT Val158Met polymorphism and antipsychotic response, which was consistent in both Caucasian and Asian patient populations. Genotyping of patients for predicting antipsychotic response may be relevant for future randomized clinical trials.

Summary: The research indicates that women in a high estradiol state tend to rely more on model-free learning, especially during periods of increased learning effort. However, model-based control remains unchanged by hormonal state. Additionally, individual genetic differences play a role in how estradiol affects learning strategies.

Summary: The study did not find a significant association between Val homozygosity and ADHD symptoms, psychopathy, or cognitive functioning in offenders. The lack of differences in allelic or genotype frequencies between the study sample and the general Swedish population suggests that Val homozygosity is not overrepresented in criminal offenders.

Summary: This study found that the catechol-O-methyltransferase (COMT) Val158Met polymorphism moderates the relationship between maternal rearing styles and loneliness, and loneliness further affects life satisfaction as a mediator. In addition, the effects of COMT Val158Met maternal rejection on loneliness and maternal rejection on Val/Val adults' life satisfaction via loneliness existed across different age groups.

Summary: While people with aversive personality traits are typically not associated with prosocial behavior, a few studies suggest that prosocial behavior can coexist with the Dark Tetrad. This study examines the relationships between the Dark Tetrad and charitable giving, finding that everyday sadism predicts keeping more money for oneself. Donations to animal charities are predicted by being a woman with higher agreeableness and lower sadism scores. Additionally, age, psychopathy, and narcissism predict the importance of public recognition from donations.

Summary: This research explores the impact of gift giving on consumers' subsequent indulgence in affordable luxury and finds that the motivation underlying gift giving plays a role. Consumers who give gifts with an altruistic motivation are more likely to indulge in affordable luxury, depending on their perception of the morality of indulgences.

Summary: This study investigated age differences in willingness to engage in effortful and effortless prosocial behavior. It found that older adults were more prosocial than younger adults when the prosocial activities were effortless, but less prosocial when the activities required effort. This suggests that older adults have a higher willingness to engage in prosocial behavior, but physical resource constraints may limit their ability to participate in effortful prosocial activities.

Summary: This study explores children's understanding of kindness through qualitative interviews using puppets. 33 children aged 5-6 were interviewed and 4 themes were developed. The findings have implications for future research on prosocial development and the design of kindness-based interventions, as well as providing an ecologically valid method of inquiry for use with young children.

Summary: Humans are a highly prosocial species, with neurobiological roots of prosocial behavior deeply embedded in the neuroendocrine architecture of the brain, particularly through the modulatory role of the neuropeptide hormone oxytocin. The review provides insights into oxytocin's impact on care-based altruism, cooperation, and conflict, as well as its potential for therapeutic interventions in psychiatric disorders characterized by social dysfunction.

Summary: Research shows that children display prosocial behaviors from a young age, initially driven by sympathy. As they develop, their behaviors become more complex and strategic, serving purposes such as seeking social approval, reciprocity, and navigating social obligations.

Summary: Understanding the psychological basis of individuals' voting intentions is crucial as it can have an impact on political developments. This study investigated the associations between individuals' satisfaction of Maslow's five basic needs and their voting intentions in a German sample, and compared these findings with associations between personality traits and voting intentions.

Summary: The aim of this study was to investigate the associations between problematic online gaming, gambling, shopping, pornography use, and social networking in an international gamer population. The results showed small-to-medium positive correlations between problematic online gaming and other problematic behaviors. However, exploratory graph analysis revealed that all Internet-based problematic behaviors were separate entities. Games were the most prevalent problematic behavior, followed by social networking, gambling, and pornography.

Summary: This study examined the psychometric properties of the Chinese version of the Exercise Dependence Scale-Revised (EDS-C) in a sample of Chinese exercisers. The results showed that the EDS-C has a robust factor structure, gender-based invariance, good internal consistency and test-retest reliability. Additionally, positive associations were found between the EDS-C and exercise frequency, eating disorder symptoms, body image inflexibility, and generalized anxiety symptoms.

Summary: This study investigates the amount of money individuals are willing to accept (WTA) to discontinue using prominent Chinese social media platforms (WeChat/QQ) and the willingness to pay (WTP) for using these platforms. It also examines the disparities between WTA and WTP, and their psychological correlates in terms of personality and social media use habits. The findings reveal a generally low acceptance to pay for social media use and negative association between individual differences in disparities and Openness across social media platforms.

Summary: This study retrieved the profile pictures of 2234 Italian Facebook users and analyzed them along with self-report questionnaires and demographic variables. The pictures were scored for emotional expression using two commercial services, and the dataset was used to explore the association between demographic variables, personality traits, and emotional expression. This dataset is valuable for researchers studying social media users' personality and emotional expression.

Summary: This study explored the severity of gaming disorder and identified four subtypes: normative gamers, occasional gamers, problematic gamers, and addictive gamers. Problematic gamers, addictive gamers, and occasional gamers showed higher severity of problematic smartphone use, depression, and a higher proportion of male participants compared to normative gamers. Only problematic gamers exhibited significant positive associations with anxiety severity compared to the other groups.

Summary: Recent research has found a mild association between higher neuroticism and a tendency towards problematic social media use. However, the fear of missing out (FoMO) has emerged as a critical factor in this association. This study aimed to investigate the personality-PSMU association and the less-studied mediation effect of FoMO. The results showed significant effects of neuroticism on PSMU for both cultural groups, with FoMO fully mediating the effect for the European sample and partially mediating the effect for the Arab sample.

Summary: This study investigated the relationship between stressful life events (SLEs) and Gambling Disorder (GD), and found that gambling-related cognitive distortions and difficulty in emotion regulation mediate this relationship. The findings suggest that individuals who experience SLEs may be more likely to develop GD due to their belief in gambling-related cognitive distortions and difficulty in regulating their emotions.
