Putting feelings into words (affect labeling) has long been thought to help manage negative emotional experiences; however, the mechanisms by which affect labeling produces this benefit remain largely unknown. Recent neuroimaging studies suggest a possible neurocognitive pathway for process, but methodological limitations of previous have prevented strong inferences from being drawn. A functional magnetic resonance imaging study was conducted remedy these limitations. The results indicated...
Aversive emotional reactions to real or imagined social harms infuse moral judgment and motivate prosocial behavior. Here, we show that the neurotransmitter serotonin directly alters both behavior through increasing subjects’ aversion personally harming others. We enhanced in healthy volunteers with citalopram (a selective reuptake inhibitor) contrasted its effects a pharmacological control treatment placebo on tests of measured drugs' set 'dilemmas' pitting utilitarian outcomes (e.g.,...
Serotonin (5-HT) has long been implicated in social behavior and impulsivity, but the mechanisms through which it modulates self-control remain unclear. We observed effects of manipulating 5-HT function on ultimatum game, where players must decide whether to accept or reject fair unfair monetary offers from another player. Participants with depleted levels rejected a greater proportion offers, not without showing changes mood, fairness judgment, basic reward processing, response inhibition....

Significance Concern for the welfare of others is a key component moral decision making and disturbed in antisocial criminal behavior. However, little known about how people evaluate costs others’ suffering. Past studies have examined people’s judgments hypothetical scenarios, but there evidence that cannot accurately predict actual Here we addressed this issue by measuring much money will sacrifice to reduce number painful electric shocks delivered either themselves or an anonymous...
Moral judgments play a critical role in motivating and enforcing human cooperation, research on the proximate mechanisms of moral highlights importance intuitive, automatic processes forming such judgments. Intuitive often share characteristics with deontological theories normative ethics, which argue that certain acts (such as killing) are absolutely wrong, regardless their consequences. Why do intuitions typically follow prescriptions, opposed to those other ethical theories? Here, we test...
With the COVID-19 pandemic threatening millions of lives, changing our behaviors to prevent spread disease is a moral imperative. Here, we investigated persuasiveness messages inspired by three major traditions. A sample US participants representative for age, sex and race/ethnicity (N=1032) viewed from either leader or citizen containing deontological, virtue-based, utilitarian, non-moral justifications adopting social distancing during pandemic. We measured messages’ effects on...
With more than 3 billion users, online social networks represent an important venue for moral and political discourse have been used to organize revolutions, influence elections, raise awareness of issues. These examples rely on a common process be effective: the ability engage users spread moralized content through networks. Here, we review evidence that expressions emotion play role in (a phenomenon call contagion). Next, propose psychological model called motivation, attention, design...
The neuromodulator serotonin has been implicated in a large number of affective and executive functions, but its precise contribution to motivation remains unclear. One influential hypothesis aversive processing; another proposed more general role for behavioral inhibition. Because inhibition is prepotent reaction outcomes, it challenge reconcile these two accounts. Here, we show that critical punishment-induced not overall motor response or reporting outcomes. We used acute tryptophan...
Although multiple neuroimaging studies suggest that affect labeling (i.e., putting feelings into words) can dampen affect-related responses in the amygdala, consequences of have not been examined other channels emotional responding. We conducted four examining effect on self-reported experience. In study one, distress was lower during labeling, compared to passive watching, negative pictures. Studies two and three added reappraisal distraction conditions, respectively. Affect showed similar...
Moral outrage shapes fundamental aspects of social life and is now widespread in online networks. Here, we show how learning processes amplify moral expressions over time. In two preregistered observational studies on Twitter (7331 users 12.7 million total tweets) behavioral experiments (N = 240), find that positive feedback for increases the likelihood future expressions, consistent with principles reinforcement learning. addition, conform their to expressive norms networks, suggesting norm...
Past research suggests that use of psychedelic substances such as LSD or psilocybin may have positive effects on mood and feelings social connectedness. These psychological are thought to be highly sensitive context, but robust direct evidence for them in a naturalistic setting is scarce. In series field studies involving over 1,200 participants across six multiday mass gatherings the United States Kingdom, we investigated substance transformative experience, connectedness, mood. This...
The COVID-19 pandemic represents a massive global health crisis. Because the crisis requires large-scale behaviour change and places significant psychological burdens on individuals, insights from social behavioural sciences can be used to help align human behavior with recommendations of epidemiologists public experts. Here we discuss evidence selection research topics relevant pandemics, including work navigating threats, cultural influences behaviour, science communication, moral...
Human cooperation may partly depend on the presence of individuals willing to incur personal costs punish noncooperators.The psychological factors that motivate such 'altruistic punishment' are not fully understood; some have argued altruistic punishment is a deliberate act norm enforcement requires self-control, while others claim it an impulsive driven primarily by emotion.In current study, we addressed this question examining relationship between choice and in ultimatum game.As...
BackgroundReduced levels of serotonin (5-HT) within prefrontal cortex (PFC)–amygdala circuits have long been implicated in impulsive aggression. However, whether lowering 5-HT alters the dynamic interplay between PFC and amygdala has not directly tested humans. It is known that manipulating via acute tryptophan depletion (ATD) causes variable effects on brain responses to a variety emotional stimuli, but it remains unclear ATD affects functional connectivity neural networks involved...
Social cognition is important in everyday-life social interactions. The cognitive effects of 3,4-methylenedioxymethamphetamine (MDMA, ‘ecstasy’) and methylphenidate (both used for neuroenhancement as party drugs) are largely unknown. We investigated the acute MDMA (75 mg), (40 mg) placebo using Facial Emotion Recognition Task, Multifaceted Empathy Test, Movie Assessment Cognition, Value Orientation Test Moral Judgment Task a cross-over study 30 healthy subjects. Additionally, subjective,...
