  1. Placebo interventions resulted in more rapid performance with a smaller likelihood of errors.
  2. aLU = low-uncertainty; HU = high-uncertainty.
  3. bThe model was fit to log-transformed reaction times.
  4. cThe effect of trial was rescaled to steps of 20 trials.
  5. dNumbers indicate posterior mean and 95% HDI.
