This study shows that confidence is shaped by decision goals, not just evidence, and introduces a model to explain this goal-dependent confidence formation.

The paper introduces a reinforcement-learning framework called Sparse Cognitive Graph (SCG) that models goal-directed behavior through dynamic graph reconfiguration, showing it explains diverse behavioral regimes and predicts population activity geometry.

The paper shows humans actively seek confirming evidence for their choices, leading to biased decision-making when revising earlier decisions.

This study shows that valuation of sensory features drives abstraction during learning, with value signals in the ventromedial prefrontal cortex guiding behavior and decision-making.

This paper shows that visual attention modulates goal-relevant evidence rather than increasing value in decision-making tasks.
