Local and global reward learning in the lateral frontal cortex show differential development during human adolescence
Fig 2
Performance in probabilistic 3-choice learning task increased during adolescence.
(A) Young adults, compared to adolescents, earned more total rewards in the study. (B) This was also reflected in a linear increase in the total rewards earned across age. (C) The frequency of choosing the highest value option was higher in young adults. (D) It also increased across age. Note that chance performance in this 3-choice task is 0.33. (“x”s indicate individual participants; left plots show mean −/+ SEM; solid line in the right plots indicate linear trend; dashed line represented 95th% confidence interval; * p < 0.05). Data for A-D are available in S1 Data (Figure2 tab).
