ABSTRACT
Previous work has established that neural oscillations can temporally synchronise with the occurrence of multi-unit linguistic representations but that neural synchrony to phrase boundaries is reduced in the absence of lexical content . In this study, we extend these findings to test whether reducing parsing ambiguity eliminates the reduction in phrase tracking associated with a lack of lexical content. Building on previous work, we reduced word-level parsing ambiguity by visually presenting sentences, and we reduced phrase-level parsing ambiguities by using the caused-motion construction for all sentences. Results indicated no difference in word or phrase-level tracking when comparing English and jabberwocky stimuli. We interpret this finding as indicating that tracking phrase structure can take place in the absence of content words if parsing ambiguities are sufficiently reduced.
