Given the importance of friendships during challenging times and the mixed associations reported between personality traits and disease-related behaviors, we investigated the influence of personality traits on friendships during the COVID-19 pandemic and how both influenced risky behaviors. In November 2020, we asked participants about their reactions to friends’ behavior as part of a larger study. We found that agreeableness and neuroticism predicted participants being more concerned about COVID-19 and bothered by friends’ risky behavior, and extraversion predicted enjoying helping friends during the pandemic. Our results suggest that personality influences how individuals cope with their friends’ risky behaviors. This work could be relevant for developing interventions to reduce risk taking during the pandemic, such as using friendships to reinforce adherence to public health guidelines.

Objective: ADHD in adolescents and low level of parental monitoring have been associated with increased risk-taking behavior. The present study examined whether parental knowledge of the child’s whereabouts mediates the correlations between adolescent ADHD symptoms and risk-taking behavior. Method: Ninety-two adolescents and their parents completed questionnaires assessing perceptions of parents’ monitoring, engagement in risk-taking behaviors, and ADHD symptoms. Results: Greater engagement in risk-taking behavior correlated with higher levels of ADHD symptoms and decreased parental monitoring. Mediation analysis revealed both direct effect of ADHD symptoms on risk-taking behavior and an indirect effect mediated by level of parental knowledge. Conclusion: These findings suggest that parental knowledge is negatively affected by the presence of ADHD symptoms, and may in turn lead to risk-taking behavior. The findings emphasize the need to target parenting and in particular parental knowledge of the child’s whereabouts to reduce risk-taking behaviors among youth with ADHD.

Humans live not only in a physical world but also in a mental world. Theory of mind reflects the understanding that the mind is comprised of different mental states, such as intentions, desires, and beliefs. This conception of the mind is a critical achievement in human development because it directly impacts effective communication and social interaction. It allows for the understanding of others’ behaviors by inferring their mental states. The formation of a theory of mind has been a central topic in psychology, neuroscience, cognitive science, and philosophy. It impacts related processes, such as communication skills, perspective-taking ability, and social cognition. Across the life span, the understanding of the mind becomes increasingly complex. Early in development, infants and toddlers can discern the intentions of others. Later, more sophisticated reasoning about the mental states of others becomes possible. For instance, the ability to follow and understand the recursive thought that “Sam believes, that Mary said, that Jose wanted . . .” develops. Additionally, within distinctive developmental time periods, people differ in their ability to take into account mental states. Once people’s beliefs, including their misconceptions, are identified, it is possible to generate effective communication strategies designed to teach, learn, and even reduce risk-taking behaviors.

AbstractUsing a proprietary database of currency trades, this paper explores the effects of trading gains and losses on risk-taking among large institutional investors. We find that institutional investors, unlike individuals, are not prone to the disposition effect. Instead, institutions aggressively reduce risk following losses and mildly increase risk following gains. This asymmetry is more pronounced later in the calendar year and among older and more experienced funds. We show that such performance dependence is consistent with dynamic loss aversion (Barberis, Huang, and Santos (2001)) and overconfidence. In addition, prior institutional gains and losses have palpable implications for future prices.
