Zusammenfassung (Englisch)

The present study investigated oscillatory brain dynamics during self-paced sentence-level processing. Participants read fully correct sentences, sentences containing a semantic violation and “sentences” in which the order of the words was randomized. At the target word level, fixations on semantically unrelated words elicited a lower-beta band (1318 Hz) desynchronization. At the sentence level, gamma power (3155 Hz) increased linearly for syntactically correct sentences, but not when the order of the words was randomized. In the 300900 ms time window after sentence onsets, theta power (47 Hz) was greater for syntactically correct sentences as compared to sentences where no syntactic structure was preserved (random words condition). We interpret our results as conforming with a recently formulated predictive-coding framework for oscillatory neural dynamics during sentence-level language comprehension. Additionally, we discuss how our results relate to previous findings with serial visual presentation vs. self-paced reading.
