Learning from other people's experience: A neuroimaging study of decisional interactive-learning

►Risk-aptitude is influenced by both 1st and 3rd-person previous regret and relief ►Specific brain regions track previous regret and relief outcomes at the next choice ►Distinct regions track the previous outcomes that increase or decrease risk-seeking ►The regions tracking past outcomes are also active after observing others' outcomes ►A resonant neural mechanism may subserve interactive-learning in decision-making
