Memory guidance of value-based decision making at an abstract level of representation

Abstract Value-based decisions about alternatives we have never experienced can be guided by associations between current choice options and memories of prior reward. A critical question is how similar memories need to be to the current situation to effectively guide decisions. We address this quest...
