Testosterone enhances amygdala reactions to social threat, but it remains unclear whether this neuroendocrine mechanism is relevant for understanding its dominance-enhancing properties; namely, whether testosterone biases the human amygdala toward threat approach. This pharmacological functional magnetic-resonance imaging study shows that testosterone(More)
In social contexts, errors have a special significance and often bear consequences for others. Thinking about others and drawing social inferences in interpersonal games engages the mentalizing system. We used neuroimaging to investigate the differences in brain activations between errors that affect only agents themselves and errors that additionally(More)
Fairness considerations are a strong motivational force in social decision-making. Here, we investigated the role of intentionality in response to unfair offers in the Ultimatum Game by manipulating both proposers' degree of control over the selection of offers and the context pertaining to the outcomes of offers proposers can choose from. As a result, the(More)
Although 'irrational' decision-making has been linked to depression, the contribution of biases in information processing to these findings remains unknown. To investigate the impact of cognitive biases and aberrant processing of facial emotions on social decision-making, we manipulated both context-related and emotion-related information in a modified(More)
Impairments in emotion recognition and psychosocial functioning are a robust phenomenon in schizophrenia and may affect motivational behavior, particularly during socio-emotional interactions. To characterize potential deficits and their interplay, we assessed social motivation covering various facets, such as implicit and explicit approach-avoidance(More)
Oxytocin attenuates responses to stress and threat (e.g., by fostering social approach in animals), but direct investigations of whether the hormone also facilitates approach-related social behaviors in humans are lacking. To assess approach-avoidance tendencies, we had participants respond to images of happy and angry faces with direct or averted gaze by(More)
Oxytocin (OXT) has been implicated in prosocial behaviors such as trust and generosity. Yet, these effects appear to strongly depend on characteristics of the situation and the people with whom we interact or make decisions. Norms and rules can facilitate and guide our actions, with fairness being a particularly salient and fundamental norm. The current(More)
One of the most well-known findings in human oxytocin research is its beneficial effect on "mind-reading", i.e., inferring others' mental states just from the eye region in the Reading the Mind in the Eyes Test (RMET). Previous studies have partially confirmed these improvements and have further shown that they depend both on baseline social-emotional(More)
The 17q21.31 microdeletion syndrome with its characteristic features including developmental delay, moderate intellectual disability, facial dysmorphisms, and anomalies of the brain and multiple organ systems was recently described. As to its behavioral profile, scarce data from clinical observations have suggested a remarkably amiable, friendly(More)
Communicating threats and stress via biological signaling is common in animals. In humans, androstadienone (ANDR), a synthetic male steroid, is a socially relevant chemosignal exhibited to increase positive mood and cortisol levels specifically in (periovulatory) females in positively arousing contexts. In a negative context, we expected that such effects(More)
