For the last century, economists have assumed that agents have 'deep' time preferences -- in other words, agents value pleasures and pains in t years more than pleasures and pains in t+1 years. By contrast, philosophers have argued that discounting future rewards results from `'myopia,’’ i.e. imperfect foresight. We develop this alternative hypothesis. Specifically, we show that time discounting arises naturally when a perfectly patient Bayesian decision-maker receives noisy signals about the future (instead of being able to make noiseless…

Typically, people cannot engage in more than a few — and sometimes only a single — control-demanding task at once. Limited capacity was a defining element in the earliest conceptualizations of cognitive control, it remains one of the most widely accepted axioms of cognitive psychology, and is even the basis for some laws (e.g., against the use of mobile devices while driving). It…

In a first study, participants played one-shot two-player normal-form games in which either, neither, or only one of the players had a dominant strategy. Our method allowed us to predict whether the decision process would lead to equilibrium choices or not, and to attribute out-of-equilibrium responses to limited…

The study of information acquisition lies at the intersection of three disciplines: neuroscience, psychology and economics. This symposium brings together speakers from each of these areas to provide their perspectives on how attention is modeled in their fields. Dean (Economics) will focus on recent advances in the study of 'rational inattention,' which models a decision maker who allocates attention optimally given costs and benefits of…
Find out more »Goal-directed human behaviors are driven by motives. Motives are, however, purely mental constructs that are not directly observable. Here, we show that the brain’s functional network architecture captures information that predicts different motives behind the same altruistic act with high accuracy. In contrast, mere activity in these regions contains no information about motives. Empathy-based altruism is primarily characterized by a positive connectivity from the anterior cingulate cortex (ACC) to the anterior insula (AI), whereas reciprocity-based altruism additionally invokes strong positive…
