Extended Data Fig. 1 — Trial number used as proxy measure for sweet-fat solution expectation. (A) Cluster power plotted as a function of trial number in the task (top: individual trial power, bottom: smoothed data by averaging 3 consecutive trial values). (B) Cluster power in the first versus last 20 trials of the task for the neutral (top) and sweet-fat (bottom) conditions. Note that the last 20 trials had significantly higher cluster power compared to the first 20 trials for the sweet-fat (p = 0.014, one-sided, unpaired permutation testing) but not for the taste-neutral condition (p = 0.198). NS. = non-significant, * = p < .05, error bars represent standard error of the mean across pooled trials.
