D, Phonological decoding; A, form-sound association; S, naming speed; M, memory ability; RT, reaction time; LOC, lateral occipital cortex; PreCu, precuneus; ITG/MTG/STG, inferior/middle/superior temporal gyrus; AG, angular gyrus; Ins, insula; TPJ, temporal-parietal junction; SFG/MFG, superior/middle frontal gyrus; PCC, posterior cingulate cortex; ACC, anterior cingulate cortex; VMPFC, ventromedial prefrontal cortex.
**p < 0.01,
*p < 0.05,
ap < 0.10, nsp > 0.10. Significance denotes test of prediction accuracy difference between naming speed and other two reading components as well as measures of cognitive abilities.
