Increasing the robustness limit R̂ helps recover performance lost due to feedback mistuning. Results of simulation are plotted with fitting lines. Inset: we illustrate this by moving in parameter space from the mistuned model to the recovery model, by changing R̂ = 0 → 1.25. The impact on decision performance is shown for both the controlled duration (A) and reaction time (B) tasks. We find that R̂ > 0 yields a performance gain for the recovery model compared with the mistuned model (i.e., for a fixed accuracy, mean reaction time is increased).
