Lisa Bas’ new article reviews insights from computational models and social neuroscience into motivations, precursors, and mechanisms of altruistic decision-making. The paper introduces theoretical and methodological tools, discusses potential pitfalls, and provides recommendations for researchers interested in applying a computational approach to their research. The review also discusses the utility of this approach to study lifespan differences in social preference in late adulthood, a crucial future direction in aging global populations.
