Cross-correlation matrix and behavioral regression coefficients.
(A) Group cross-correlation matrix depicting mean correlation (r) across participants between reward probabilities, expected values, and reward magnitudes of chosen, next best, and worst options. (B) Mean regression coefficients (i.e., parameter estimates) related to the reward probabilities (left column) and reward magnitudes (right column) of the options with the highest, middle, and lowest expected value derived from a logistic regression on optimal choices (i.e., choices of the option with the highest expected value). Error bars represent standard error of the mean (s.e.m.).
