Figure 3

Grand-average event-related potential (ERP) waveforms measured at the anterior [(F3+F1+Fz+F2+F4+FC3+FC1+FCz+FC2+FC4)/10] and posterior [(CP3+CP1+CPZ+CP2+CP4+P3+P1+Pz+P2+P4)/10] regions for the subordinate masking, basic masking and subordinate-superordinate-subordinate. (A) The grand-averaged waveforms elicited by subordinate masking stimulus and basic masking stimulus and the difference waveforms (subordinate minus basic) in the anterior and posterior regions, as well as the topographies of the difference waveforms at 150–250 ms and 300–400 ms. (B) Grand-averaged waveforms elicited by subordinate masking stimulus and superordinate masking stimulus and the difference waveforms (subordinate minus superordinate) in the anterior and posterior regions, as well as the topographies of the difference waveforms at 150–250 ms and 300–400 ms. (C) Grand-averaged waveforms elicited by basic masking stimulus and superordinate masking stimulus and the different waveforms at 150–250 ms and 300–400 ms.
