Abstract Recent evidence indicates that neural populations exhibit synchronous firing at phrase boundaries to facilitate the encoding of syntactic units during speech comprehension. However, good-enough processing accounts comprehension suggest detailed analysis may not always be necessary for successful interpretation, especially when listeners can deduce meaning from lexical-semantic contexts. In this brief report, we evaluate notion and assess whether synchrony is modulated by local content. To end, reanalyzed an open-source EEG dataset, consisting brain recordings obtained while participants passively listened audiobook. determine boundaries, computed mutual information (MI) between delta band activity (< 3Hz) hierarchically derived structures each sentence in We then quantified local-lexical semantic contexts using dissimilarity values were high-dimensional vectors co-occurrence. regressed MI against sentence’s values, linear mixed-effects models. Results indicated showed a positive relationship with dissimilarity. interpret finding as listeners’ reliance on contexts, consistent accounts.

Abstract Studies of perception have long shown that the brain adds information to its sensory analysis physical environment. A touchstone example for humans is language use: comprehend a signal like speech, must add linguistic knowledge, including syntax. Yet, syntactic rules and representations are atemporal (i.e., abstract not bound by time), so they be translated into time-varying signals speech comprehension production. Here, we test three different models temporal spell-out structure against activity people listening Dutch stories: an integratory bottom-up parser, predictive top-down mildly left-corner parser. These build exactly same but differ in when added – this difference captured (temporal distribution the) complexity metric ‘incremental node count’. Using response function with both acoustic information-theoretic control predictors, counts were regressed source-reconstructed delta-band acquired magnetoencephalography. Neural dynamics left frontal regions most strongly reflect derived method, which postulates syntax early time, suggesting building important component sentence comprehension. The absence strong effects model further suggests strategy does represent well, contrast what has been found English. Understanding projects knowledge onto whether done language-specific ways, will inform constrain development mechanistic syntactic-structure brain.

Abstract Although psycho-/neuro-linguistics has assumed a distinction between morphological and syntactic structure building as in traditional theoretical linguistics, this been increasingly challenged by linguists recent years. Opposing sharp, lexicalist morphology syntax, non-lexicalist theories propose common morpho-syntactic operations that cut across the realms of “morphology” “syntax”, which are considered distinct territories theories. Taking advantage two pairs contrasts Mandarin Chinese with desirable linguistic properties, namely compound vs. simplex nouns (the contrast, differing complexity per theories) separable inseparable verbs “syntax” theories), we report one first pieces evidence for shared neural responses language comprehension, supporting view where computations employed building. Specifically, observed both modulated left anterior centro-parietal electrodes an priori 275:400 ms time window, corroborated topographical similarity analyses. These results serve preliminary yet prima facie towards comprehension.
