abstract = {Computational models of social learning and decision-making
provide mechanistic tools toinvestigate the neural
mechanisms that are involved in understanding other people.
Whilemost studies employ explicit instructions to learn from
social cues, everyday life is characterizedby the
spontaneous use of such signals (e.g., the gaze of others)
to infer on internalstates such as intentions. To
investigate the neural mechanisms of the impact of gaze cues
on learning and decision-making, we acquired behavioural and
fMRI data from50 participants performing a probabilistic
task, in which cards with varying winningprobabilities had
to be chosen. In addition, the task included a
computer-generated facethat gazed towards one of these cards
providing implicit advice. Participants’ individualbelief
trajectories were inferred using a hierarchical Gaussian
filter (HGF) and used aspredictors in a linear model of
neuronal activation. During learning, social prediction
errorswere correlated with activity in inferior frontal
gyrus and insula. During decision-making,the belief about
the accuracy of the social cue was correlated with activity
in inferiortemporal gyrus, putamen and pallidum while the
putamen and insula showed activity as afunction of
individual differences in weighting the social cue during
decision-making. Ourfindings demonstrate that model-based
fMRI can give insight into the behavioural andneural aspects
of spontaneous social cue integration in learning and
decision-making.They provide evidence for a mechanistic
involvement of specific components of thebasal ganglia in
subserving these processes.},
