A, Longitudinal graphic representation of age at both time points and contrast values for win > lose for the left nucleus accumbens on both time points. Individual subjects are represented by individual lines. Subjects measured only once are represented by points. Right nucleus accumbens, not represented in a figure, shows similar effects. B, Predicted values for contrast values for win > lose for the left nucleus accumbens based on the optimal fitting model. Right nucleus accumbens, not represented in a figure, shows similar effects. Dotted lines represent 95% confidence interval.
