The posterior semantic asymmetry (PSA): specific to written not auditory semantic word processing

The present study replicates the finding of a posterior semantic asymmetry (PSA; Koppehele-Gossel et al., Brain Lang 157–158:35–43, 2016), a lateralized event-related potential (ERP) suggested to reflect semantic activation from visually presented single words. This ERP negativity, derived from the subtraction of right-side from left-side scalp activity, again peaked around 300 ms at temporoparietal electrodes and was more pronounced in a...
