The paper shows humans use others' movement to infer confidence and guide collective decisions, improving accuracy when confidence is intermediate.

The paper identifies neural signatures of sensory variability in EEG signals and links them to individual differences in metacognitive evaluation.

The paper investigates how shared and subjective uncertainty align during social interactions using neural and behavioral data, finding that social information modulates evidence accumulation and neural dynamics.

This study identifies distinct neural mechanisms for informational and normative conformity using fMRI during a social decision-making task.

This study shows that sharing responsibility in social decision-making reduces the sense of agency, affecting motor preparation and outcome processing in the brain.

This study tests three hypotheses about how imitation influences human reinforcement learning and finds that value shaping is the most supported model.

This study shows that group decision-making by adolescents is optimal, with performance at adult levels, challenging previous views of adolescent decision-making as sub-optimal.

This paper investigates how outcome variance affects decision-making and confidence in uncertain value-based choices, proposing a stochastic satisficing model to explain confidence ratings.

The paper shows advisers strategically modulate their confidence based on their influence level and relative merit, with distinct brain regions tracking these factors and influencing behavior.

The paper investigates individual differences in confidence reporting by analyzing how people estimate confidence under uncertainty, finding that some individuals use perceived probability while others use Fisher information.
