Successful goal-directed behavior requires not only correct action selection, planning, and
execution but also the ability to flexibly adapt behavior when performance problems occur or …

What kinds of processes and representations make joint action possible? In this paper, we
suggest a minimal architecture for joint action that focuses on representations, action …

Intergroup competition makes social identity salient, which in turn affects how people
respond to competitors' hardships. The failures of an in-group member are painful, whereas …

Learning occurs when an outcome differs from expectations, generating a reward prediction
error signal (RPE). The RPE signal has been hypothesized to simultaneously embody the …

The capacity to evaluate the outcomes of our actions is fundamental for adapting and
optimizing behavior and depends on an action-monitoring system that assesses ongoing …

Reinforcement learning enables organisms to adjust their behavior in order to maximize
rewards. Electrophysiological recordings of dopaminergic midbrain neurons have shown …

A fundamental challenge in social cognition is how humans learn another person's values to
predict their decision-making behavior. This form of learning is often assumed to require …

Research has shown that the brain is constantly making predictions about future events.
Theories of prediction in perception, action and learning suggest that the brain serves to …

Neuroimaging studies typically identify neural activity correlated with the predictions of
highly parameterized models, like the many reward prediction error (RPE) models used to …

What is a group? How do we know to which groups we belong? How do we assign others to
groups? A great deal of theorizing across the social sciences, has conceptualized “groups” …
