Peer threat evaluations shape one’s own threat perceptions and feelings of distress
We are continuously exposed to what others think and feel about content online. How do others' evaluations shared in this medium influence our own beliefs and emotional responses? In two pre-registered studies, we investigated the social transmission of threat and safety evaluations in a paradigm that mimicked online social media platforms. In Study 1 (N = 103), participants viewed images and indicated how distressed they made them feel. Particip…
Delusion-proneness predicts Covid-19 vaccination behavior
Our results suggest that delusion-proneness is a key factor for attaining conspiracy beliefs, at least in relation to COVID-19 pandemic, and associated with lower vaccination rates as well as longer time to get vaccinated
The transfer of social threat learning to decision making is robust to extinction
Through traditional mass media and online social media, we are almost constantly exposed to second-hand experiences of trauma and violence, providing ample opportunities for us to learn about threats through social means. This social threat learning can influence instrumental decision making through a social learning to decision-making transfer process, resembling the so-called Pavlovian to instrumental transfer effect, resulting in consequences …
From inspiration to restoration
s = 1,131), conducted in four understudied countries directly affected or threatened by intergroup conflict, we demonstrated that induced moral elevation elicits important cognitive and emotional shifts toward adversarial groups, resulting in improved intergroup relations. Specifically, we show that inducing moral elevation through stories of outgroup moral exemplars (individuals who have risked their life to save the life of an outgroup member) …
Threaten and affirm
Information about ingroup moral violations against outgroups evoke defensiveness resulting in low support for reparations to be provided to members of these groups. Yet it remains unknown if reminders of ingroup harmdoings could also enhance moral engagement rather than disengagement. In this paper, we report experimental evidence from three studies ( ns = 625) set in the context of historical atrocities committed against indigenous people in Swe…
National identity predicts public health support during a global pandemic
Changing collective behaviour and supporting non-pharmaceutical interventions is an important component in mitigating virus transmission during a pandemic. In a large international collaboration (Study 1, N = 49,968 across 67 countries), we investigated self-reported factors associated with public health behaviours (e.g., spatial distancing and stricter hygiene) and endorsed public policy interventions (e.g., closing bars and restaurants) during …
The Interpersonal Neuroscience of Social Learning
The study of the brain mechanisms underpinning social behavior is currently undergoing a paradigm shift, moving its focus from single individuals to the real-time interaction among groups of individuals. Although this development opens unprecedented opportunities to study how interpersonal brain activity shapes behaviors through learning, there have been few direct connections to the rich field of learning science. Our article examines how the ra…
Predicting attitudinal and behavioral responses to Covid-19 pandemic using machine learning
At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions. In this study, we applied machine learning on the multi-national data collected by the International Collaboration on the Social…
Psychological well-being is associated with prosociality during the Covid-19 pandemic
This study revisited the link between psychological well-being and prosociality during a global crisis from a cross-cultural perspective. We surveyed two large samples of Chinese ( N 1 = 1,030; 89 regions; May 1-6, 2020) and Swedish ( N 2 = 1,160; 22 regions; May 14-24, 2020) individuals during the coronavirus (COVID-19) pandemic. Across both countries, we observed that psychological well-being was strongly associated with one's self-reported ten…
Does gender matter? The association between different digital media activities and adolescent well-being
Our study shows the importance of research going beyond studying the time spent on social media to examine how different kinds of social media activities are associated with well-being. Consistent with research in psychology, our results suggest that young girls posting information about themselves (i.e. self-presentation) might be especially vulnerable to display internalizing symptoms
Learning biases to angry and happy faces during Pavlovian aversive conditioning
Learning biases in Pavlovian aversive conditioning have been found in response to specific categories of threat-relevant stimuli, such as snakes or angry faces. This has been suggested to reflect a selective predisposition to preferentially learn to associate stimuli that provided threats to survival across evolution with aversive outcomes. Here, we contrast with this perspective by highlighting that both threatening (angry faces) and rewarding (…
Evolved Physiological Reactions
Testosterone and estrogen impact social evaluations and vicarious emotions
The abilities to "read" other peoples' intentions and emotions, and to learn from their experiences, are critical to survival. Previous studies have highlighted the role of sex hormones, notably testosterone and estrogen, in these processes. Yet it is unclear how these hormones affect social cognition and emotion using acute hormonal administration. In the present double-blind placebo-controlled study, we administered an acute exogenous dose of t…
A clash of values
Humans and nonhuman primates preferentially learn to fear and avoid archetypical fear-relevant stimuli. Yet how these learning biases influence adaptive behavior, the basic mechanistic underpinnings of these biases, and how they interact with learning experiences during the life span of an individual remain unknown. To study this, we investigated how 4 classes of fear-relevant stimuli (snakes, threatening in-group faces, racial out-group faces, a…
Learning biases underlying individual differences in sensitivity to social rejection
People vary greatly in their dispositions to anxiously expect, readily perceive, and strongly react to social rejection (rejection sensitivity [RS]) with implications for social functioning and health. Here, we examined how RS influences learning about social threat. Using a classical fear conditioning task, we established that high compared to low individuals displayed a resistance to extinction of the conditioned response to angry faces, but no…
Fear is readily associated with an out-group face in a minimal group context
Failure to Detect Mismatches Between Intention and Outcome in a Simple Decision Task
A fundamental assumption of theories of decision-making is that we detect mismatches between intention and outcome, adjust our behavior in the face of error, and adapt to changing circumstances. Is this always the case? We investigated the relation between intention, choice, and introspection. Participants made choices between presented face pairs on the basis of attractiveness, while we covertly manipulated the relationship between choice and ou…
The Role of Social Groups in the Persistence of Learned Fear
Classical fear conditioning investigates how animals learn to associate environmental stimuli with an aversive event. We examined how the mechanisms of fear conditioning apply when humans learn to associate social ingroup and outgroup members with a fearful event, with the goal of advancing our understanding of basic learning theory and social group interaction. Primates more readily associate stimuli from certain fear-relevant natural categories…
