Fig. 4: Neural results for active exposure.

A During active exposure blocks, participants (n = 23) were instructed to categorize as beer or pier ten condition-specific and two test exemplars. B Participants showed a more robust neural encoding of subphonemic F0 differences in the canonical speech condition relative to the accented speech condition, approximately 100 ms following the stimulus onset. C They also showed a more robust neural encoding of lexical differences (beer/pier) in the canonical speech condition relative to the accented speech condition, approximately 650 ms following the onset of the stimulus. Brain waves (mean and standard error mean) are shown for the following representative channels: Fz (N1), Pz (LPC).
