Note. T3 = left temporal electrode cluster; Avg Amp = average amplitude to word between 200 and 500 ms after stimulus onset; Words Understood = number of word stimuli featured in the event-related potential paradigm reportedly understood by the participant; P3 = left parietal electrode cluster; Avg Diff = average difference between word and nonword amplitudes between 200 and 500 ms after stimulus onset.
