This paper introduces a joint modeling framework that improves parameter estimation reliability in time-dependent threshold diffusion models by incorporating non-decision time measurements.

The paper investigates why people over-exploit common natural resources using neuroimaging and computational modeling, finding that ventral striatal activity modulates behavior differently for common versus private resources.

This study uses 7T fMRI to examine dopaminergic nuclei in humans, finding correlations with reward prediction error and risk in SN and VTA, and a surprise signal in SN.
