Extended Data Fig. 3: Reward predictors, together with the reward outcome, determine the choices and the next waiting time.

Same as Fig. 2, but separated for monkey G and T. (a,d) Correlation matrices of the task variables. (b,e) Predictability of the next reward from experimental and behavioral variables. The rewarded fraction of presses was calculated in each 50 press bin, then the Pearson correlation coefficient was calculated across bins between the average of the experimental variable and the rewarded fraction of presses. (c,f) Left: histograms of the next waiting time for rewarded and unrewarded presses that were made after a short, medium or long wait, determined by equal intervals in the percentile of the presses. Inset: an increase in the probability of switching when not rewarded after a short, medium or long wait. The probability of switching after being rewarded was less than 2% and therefore excluded from this analysis. Right: the same as left, but for reward ratio instead of waiting time.
