abstract = {Altruism (a costly action that benefits others) and
reciprocity (the repayment of acts in kind) differ in that
the former expresses preferences about the outcome of a
social interaction, whereas the latter requires, in
addition, ascribing intentions to others. Interestingly, an
individual’s behavior and neurophysiological activity
under outcome- versus intention-based interactions has not
been compared directly using different endowments in the
same subject and during the same session. Here, we used a
mixed version of the Dictator and the Investment games,
together with electroencephalography, to uncover a
subject’s behavior and brain activity when challenged with
endowments of different sizes in contexts that call for an
altruistic (outcome-based) versus a reciprocal
(intention-based) response. We found that subjects displayed
positive or negative reciprocity (reciprocal responses
greater or smaller than that for altruism, respectively)
depending on the amount of trust they received. Furthermore,
a subject’s late frontal negativity differed between
conditions, predicting responses to trust in
intentions-based trials. Finally, brain regions related with
mentalizing and cognitive control were the cortical sources
of this activity. Thus, our work disentangles the behavioral
components present in the repayment of trust, and sheds
light on the neural activity underlying the integration of
outcomes and perceived intentions in human economic
interactions.},
