Conditional accuracy functions for corresponding (Cs) and non-corresponding (Nc) trial types as a function of dopamine agonist state (off versus on) for (A) all patients, (B) patients with impulsive-compulsive behaviors (ICB), and (C) patients without ICB. Across panels, it is clear that errors are associated with the fastest reaction times on non-corresponding (Nc] trials, but that the pattern of error rates does not differ between agonist states. Panels B and C indicate that patients with ICB made fewer fast, impulsive action errors than patients without ICB.
