Across pairs of tasks, separately for text and false font stimuli, in the left VWFA and the two Broca's areas. See Extended Data Table 2-1 for statistics on VWFA-1 and VWFA-2 separately. For each ROI, the six p values are corrected for false discovery rate. PSC, percent signal change; SEM, standard error of mean; CI, confidence interval; LD, lexical decision task; FC, fixation color task; SC, stimulus color task; BF, Bayes factor.
