Selective attention to phonology dynamically modulates initial encoding of auditory words within the left hemisphere.
Bottom Line: Data-driven source localization analyses revealed that selective attention to phonology led to significantly greater recruitment of left-lateralized posterior and extensive temporal regions, which was notably concurrent with the rhyme-relevant information within the word.Furthermore, selective attention effects were specific to auditory stimulus encoding and not observed in response to cues, arguing against the notion that they reflect sustained task setting.Collectively, these results demonstrate that selective attention to phonology dynamically engages a left-lateralized network during the critical time-period of perception for achieving phonological analysis goals.

Mentions: TANOVAs at each time point revealed that selective attention to pho nology produced robust effects in six distinct intervals: 248–298, 330–364, 496–542, 564–628, 694–732, and 804–836 ms (Fig. 1 top; Fig. 2).
