Effects of lexical frequency. In each panel, the y axis is the mean difference between trials when the word’s lexical frequency was above vs. below the median. Unfilled bars are the effect of the left word’s frequency (averaging over the right word); filled bars are the effect of the right word’s frequency (averaging over the left word). Bars are grouped along the x axis by cue condition: D, distributed; FL, focal left; FR, focal right. (A) Accuracy of semantic categorization judgments (d′). (B) Mean BOLD response in left hemisphere VWFA-2. Asterisks indicate two-tailed P values computed from bootstrapping: **P < 0.01.
