Fig 4. Coding of offer 1 in the comparison epoch remains correlated across accept/reject conditions but with more dependence on the upcoming decision (for statistical comparison between format correlations, see Fig 5).

(A) Format analysis: (left) scatterplot of offer 1, epoch 2 regression coefficients for trials in which offer 1 is accepted (horizontal axis) versus rejected (vertical axis). Shaded error region indicates 99% credible interval, and dashed red lines indicate the 95% credible interval. The black dashed line indicates the level of correlation we would expect to see under a chance model (see main text and Materials and methods). (Middle) distribution of mean correlation coefficient of data. The mean of this distribution is represented as a red dashed line in the right panel. (Right) distribution of mean correlation coefficients expected under a chance model (black distribution) compared to the mean correlation observed in the data (red dashed line; permutation test with 1,000 permutations: p < 0.001). (B) Population analysis: (left) scatterplot of offer 1, epoch 2 absolute regression coefficients for trials in which offer 1 is accepted (horizontal axis) versus rejected (vertical axis). Shaded error region indicates 99% credible interval, and dashed red lines indicate the 95% credible interval. The black dashed line indicates the level of correlation we would expect to see under a chance model (see main text and Materials and methods). (Middle) distribution of mean correlation coefficient of data. The mean of this distribution is represented as a red dashed line in the right panel. (Right) distribution of mean correlation coefficients expected under a chance model (black distribution) compared to the mean correlation observed in the data (red dashed line; permutation test with 1,000 permutations: p < 0.001).
