A Bayesian model suggests that when interacting with a group, humans simulate the “mind of group” to choose an action.
Is the ability to represent world from perspective of another (mentalising) confined humans? Guinea baboons living in a social colony freely came play 2-players coordination game via touchscreen devices with any other baboon, or alone. In fact, both conditions, they interacted an identical Artificial Agent. Coordination Agent was more successful than solo condition. A computational mentalising model accounted for baboon’s behaviour much better simpler models that lacked components condition...
Abstract Social hierarchies can be inferred through observational learning of social relationships between individuals. Yet, little is known about the causal role specific brain regions in hierarchies. Here, using transcranial direct current stimulation, we show a medial prefrontal cortex (mPFC) versus non-social In Training phase, participants acquired knowledge and by trial error. During Test they were presented with two items from that never encountered together, requiring them to make...
Humans frequently interact with agents whose intentions can fluctuate between competition and cooperation over time. It is unclear how the brain adapts to fluctuating of others when nature interactions (to cooperate or compete) not explicitly truthfully signaled. Here, we use model-based fMRI a task in which participants thought they were playing another player. In fact, played an algorithm that alternated without signaling cooperative competitive strategies. We show neurocomputational...
Abstract Learning one’s status in a group is fundamental process building social hierarchies. Although animal studies suggest that serotonin (5-HT) signaling modulates learning hierarchies, direct evidence humans lacking. Here we determined the relationship between transporter (SERT) availability and brain systems engaged ranks combining computational approaches with simultaneous PET-fMRI acquisition healthy males. We also investigated link SERT activity non-social control condition...
Bribery is a common form of corruption that takes place when briber suborns power holder to achieve an advantageous outcome at the cost moral transgression. Although bribery has been extensively investigated in behavioral sciences, its underlying neurobiological basis remains poorly understood. Here, we employed transcranial direct-current stimulation (tDCS) combination with novel paradigm (N = 119 adults) investigate whether disruption right dorsolateral prefrontal cortex (rDLPFC) causally...
Abstract To make decisions in a social context, humans have to predict the behavior of others, an ability that is thought rely on having model other minds known as theory mind. Such becomes especially complex when number people one simultaneously interacts large and actions are anonymous. Here, we show order within group, employ Bayesian inference “mind group,” making predictions others’ while also considering effects their own group whole. We present results from decision task Volunteers...

Abstract Background To show the equivalence between specific binding ratios (SBR) of visually normal 123 I-FP-CIT SPECT scans from patients to those healthy volunteers (Hv) or without dopaminergic degeneration allow their use as a reference database. Methods The SBR values 3 groups were studied: (1) suspected Parkinsonism and no diagnostic follow-up (ScanOnlyDB: n = 764, NM/CT 670 CZT, GE Healthcare), (2) degenerative pathology after 5-year (NoDG5YearsDB: 237, Symbia T2, Siemens Medical...
The ability to decipher the intentions of other agents and mentalize how one’s own choice might influence others’ behavior is essential for social interaction, especially when these fluctuate over time between competitive cooperative strategies. Little known about this Advanced Theory Mind (AToM) develops during childhood. Is its development conceptually driven, or does it result from an increase in general information-processing capacities with age? We used a computational modeling approach...
Abstract Humans frequently interact with other agents whose intentions can fluctuate over time between competitive and cooperative strategies. How does the brain decide whether others’ are to cooperate or compete when nature of interactions is not explicitly signaled? We used model-based fMRI a task in which participants thought they were playing another player. In fact, this agent was an algorithm alternating without signaling A neurocomputational mechanism underlying arbitration experts...
Abstract Social hierarchy is a fundamental principle of social organization and an important attribute community stability development. Yet, little known about the causal role specific brain regions in learning hierarchies. Here, using transcranial direct current stimulation (tDCS), we investigated medial prefrontal cortex (mPFC) non-social In Training phase, participants(N=128) acquired knowledge parallel, by trial error. During Test they were presented with two items from hierarchies that...
