Abstract
Recent theoretical proposals identify cortical gamma (γ) oscillations as signaling a mechanistic γ operational workspace (e.g., Murphy, 2024). Following the hypothesis that first (L1) and second (L2) languages involve shared neurofunctional mechanisms (Green & Abutalebi, 2008), we document cortical γ oscillatory dynamics in processing wh-filler-gap dependencies across a clause edge such as ‘Which decision regarding/about him did Paul say that Lydie had rejected without hesitation?’ in L1 and L2 French using electroencephalography. We manipulated wh-filler grammatical specifications with modifiers (Mods) vs. lexically specified complements (Comps) and with pronouns marked for antecedent gender or not. We used cluster-based non-parametric permutation tests (Oostenveld et al., 2011) in an analysis window covering ‘said that’ in two bins: 30–100Hz (broadband γ) and 30–50Hz (low γ). Event-related power differences (ERPDs) showed greater power for Comps than Mods and for antecedent-gender-specified than gender-unspecified Comps across L1 and L2. Narrowband/low-γ effects started in advance of bridge verb access and were maintained after verb access into the subordinator. These significant effects were echoed by broadband-γ ERPDs timed with the verb and subordinator, suggesting output activity in object creation. Two bursts of between-group ERPDs in low and broadband γ, respectively, reflected the (lack of) antecedent-gender specification of pronouns in anaphora relations. Hence, these patterns of oscillatory dynamics suggest that similarities and differences between L1 and L2 are accounted for by a γ-implemented operational workspace (Murphy, 2024) that enables the creation of structural and referential chain objects (Dekydtspotter et al., 2024).
期刊介绍:
The Journal of Neurolinguistics is an international forum for the integration of the neurosciences and language sciences. JNL provides for rapid publication of novel, peer-reviewed research into the interaction between language, communication and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in communication and its breakdowns. Contributions from neurology, communication disorders, linguistics, neuropsychology and cognitive science in general are welcome. Published articles will typically address issues relating some aspect of language or speech function to its neurological substrates with clear theoretical import. Interdisciplinary work on any aspect of the biological foundations of language and its disorders resulting from brain damage is encouraged. Studies of normal subjects, with clear reference to brain functions, are appropriate. Group-studies on well defined samples and case studies with well documented lesion or nervous system dysfunction are acceptable. The journal is open to empirical reports and review articles. Special issues on aspects of the relation between language and the structure and function of the nervous system are also welcome.
