We review recent brain-scanning (fMRI) evidence that activity in certain sub-cortical structures of the human brain correlate with changes in expected reward, as well as with risk. Risk is measured by variance of payoff, as in Markowitz? theory. The brain structures form part of the dopamine...

Curiosity has been described as the "wick in the candle of learning" but its underlying mechanisms are not well-understood. We scanned subjects with fMRI while they read trivia questions. The level of curiosity when reading questions is correlated with activity in caudate regions previously...

We meta-analyzed 32 experimental "correspondence" studies investigating discrimination in the North American labor market. We collected data on 592 different social signals to examine the impact of social perception (warmth, competence) on callback rates. Our analysis found that social...

We conduct a study in which subjects trade stocks in an experimental market while we measure their brain activity using functional magnetic resonance imaging. All of the subjects trade in a suboptimal way. We use the neural data to test a “realization utility” explanation for their behavior....
