Social motivations in choice: insights from decision neuroscience
Our lives consist of a constant stream of decisions and choices, from the mundane to the highly consequential. The standard approach to experimentally examining decision-making has been to examine choices with clearly defined probabilities and outcomes, however it is an open question as to whether decision models describing these situations can be extended to choices that must be made by assessing the intentions and preferences both of oneself and of another social partner. This class of social decision-making offers a useful approach to examine more complex forms of decisions, which may in fact better approximate many of our real-life choices. I will present data from several experiments where we use economic games to observe how players decide in real, consequential, social contexts, and will discuss how we can use these brain insights to build better models of human social preferences, incorporating both psychological and neurobiological constructs.
