Function-based meta-analysis of word generation. Studies utilizing a word generation paradigm were downloaded from the BrainMap database. Papers were segregated according to stimulus and response features. Separate ALE meta-analyses were performed for each set of coordinates: overt speech responses (30 papers, 78 experiments, 604 coordinates), covert speech responses (35 papers, 92 experiments, 729 coordinates), visual stimuli (39 papers, 115 experiments, 906 coordinates), auditory stimuli (32 papers, 86 experiments, 621 coordinates), visual words (25 papers, 88 experiments, 638 coordinates), visual letters (14 papers, 38 experiments, 373 coordinates), auditory words (39 papers, 124 experiments, 1001 coordinates), and auditory letters (14 papers, 35 experiments, 279 coordinates). Results are displayed at P < 0.05, corrected. Left lateral (x = −44) and medial (x = 0) sagittal slices display the comparative meta-analytic results. In all images, the overlap between meta-analysis results is shown in yellow.
