Deciding when to leave a depleting resource to exploit another is a fundamental problem for
all decision makers. The neuronal mechanisms mediating patch-leaving decisions remain …

When has the world changed enough to warrant a new approach? The answer depends on
current needs, behavioral flexibility and prior knowledge about the environment. Formal …

In attentional models of learning, associations between actions and subsequent rewards are
stronger when outcomes are surprising, regardless of their valence. Despite the behavioral …

The neural mechanisms supporting the ability to recognize and respond to fictive outcomes,
outcomes of actions that one has not taken, remain obscure. We hypothesized that neurons …

Online review, an important form of reputation systems, has been studied intensively because
of its powerful impact on online retailers, intermediaries, and customers. However, to date, …

Neuroeconomics applies models from economics and psychology to inform neurobiological
studies of choice. This approach has revealed neural signatures of concepts like value, risk, …

In dynamic environments, adaptive behavior requires striking a balance between harvesting
currently available rewards (exploitation) and gathering information about alternative …

Foraging is a fundamental behavior, and many types of animals appear to have solved
foraging problems using a shared set of mechanisms. Perhaps the most common foraging …

A neuroethological approach to human and nonhuman primate behavior and cognition predicts
biological specializations for social life. Evidence reviewed here indicates that ancestral …

Social decisions require evaluation of costs and benefits to oneself and others. Long associated
with emotion and vigilance, the amygdala has recently been implicated in both decision-…
