Mixed-model analyses for development of cortical regions in the frontoparietal network. a Anatomical ROIs (Harvard-Oxford Cortical Atlas). Center-of-mass coordinates were (x, y, z): middle frontal gyrus (MFG) (−4, 22, 43); superior parietal lobule (SPL) (7, −48, 63); supplementary motor area (SMA) (0, −2, 58); anterior cingulate cortex (ACC) (1, 20, 24). b Predicted developmental trajectories for sensitivity to learning signals. A quadratic age effect was the best fit for MFG (no age: AIC = 2649; linear: AIC = 2651, log-like p = 0.841; quadratic: AIC = 2643, log-like p = 0.001), SMA (no age: AIC = 3017; linear: AIC = 3012, log-like p = 0.010; quadratic: AIC = 3009, log-like p = 0.020), and SPL (no age: AIC = 2717; linear: AIC = 2717, log-like p = 0.155; quadratic: AIC = 2710, log-like p = 0.004). ACC showed no age-related changes (no age: AIC = 2441; linear: AIC = 2442, log-like p = 0.403; quadratic: AIC = 2443, log-like p = 0.416) (N = 736)
