The paper develops an online decision-making battery to assess reinforcement learning and vigor, finding two distinct factors with moderate reliability and associations with mania but not depression.

The paper identifies a bi-phasic pattern of age-related dopamine D1 receptor decline, with distinct functional consequences before and after 40 years of age.

The paper replicates a finding that DRD2/ANKK1 TaqIA A1 allele carriers show reduced learning performance in reward inhibition tasks and suggests COMT Val108/158Met Met homozygotes have lower learning bias.

The paper examines how reward and dopamine affect vigor in younger and older humans, finding similar reward effects across age groups with weak dopamine receptor involvement.

The paper investigates how inferred controllability modulates Pavlovian and instrumental action selection using neural data from a Go/NoGo task.

This study investigates learning across the human lifespan using a go/no-go task, showing age-related differences in reward and punishment sensitivity.

The paper identifies a general decision-making ability, decision acuity, linked to psychopathology and distinct brain connectivity patterns in adolescents and young adults.
