Significant ERP effects according to the post hoc tests of Analysis I.

<p>Note: Significant ERP effects according to the post hoc tests of Analysis I (<i>p</i><.05) in microV with their topography in parenthesis to the presentation of non degraded (DL0), mildly degraded (DL1), and highly degraded (DL3) auditory sentences during wake, N2, and R. A: Anterior sites (F3, F4, F7, F8), C: Central sites (C3, C4, T7, T8), P: Posterior sites (P3, P4, P7, P8), CP: Central and Posterior sites, AC: Anterior and Central sites, <i>n.s.</i>: non-significant ERP effect (<i>p</i>>.05), Lg: ERP (averaged in the above-mentioned time windows) to <b>long</b> SSL incongruent sentences minus ERP to congruent sentences, S: ERP to <b>short</b> SSL incongruent sentences minus ERP to congruent sentences, SSL: ERP to long minus short SSL incongruent sentences, W: Wake, DL independent: ERP effects independent from the DL (i.e. from an interaction that did not include the DL factor).
