Figure 3. Results of general linear model analysis of the pupil dilation response during delayed reward presentation.

Figure 3

A) Value Model. Average of best-fitting beta weights for the delayed reward presentation, and delayed reward presentation parametrically modulated by RVE (relative value equivalence: the negative of the absolute difference between the subjective values of the immediate and delayed reward options), DATE/DAYS (−1 = DAYS; 1 = DATE), and subjective value of the delayed reward. B) Choice Model. Average of best-fitting beta weights for the delayed reward presentation, and delayed reward presentation parametrically modulated by DATE/DAYS (−1 = DAYS; 1 = DATE), and choice (1 = delayed reward chosen; −1 = immediate reward chosen). Error bars represent 95% CIs (* p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001).
