To identify possible differences in the brain electrical activity between lexical cohort sizes (large vs. small) and between semantic relatedness (related vs. unrelated), we calculated sLORETA images for each participant and then calculated the sLORETA images across all participants for each lexical cohort size and semantic relatedness with a time step of 50 ms from picture onset (0 ms) to 600 ms post picture presentation (Wieser et al., 2010). Furthermore, the sLORETA images were compared across conditions to determine the significant differences (corrected, p < 0.05) in the brain electrical activity, using the log-F-ratio statistic with sLORETA-built-in voxel-wise randomization tests (5,000 random permutations) (Nichols and Holmes, 2002).
