講座內容簡介

Functional specialization and plasticity are fundamental neural organizing principles, but their roles in different language systems in adult monolingual and bilingual language learners remain to be ascertained. In a series of cross-sectional and longitudinal functional MRI experiments with samples of monolingual and bilingual language learners, we examined hemispheric lateralization and learning-dependent plasticity of three language systems: reading, speech comprehension and verbal production. Converging results from these studies with monolingual and bilingual adult language learners revealed that (i) in both native and non-native languages, lateralization for language comprehension was highly variable, while language production was left-lateralized, and (ii) with increasing non-native language proficiency, reading and speech comprehension displayed substantial changes in hemispheric dominance, with languages tending to lateralize to opposite hemispheres, while verbal production remained strictly left-lateralized. These findings may explain the comprehension-production asymmetry in language acquisition and learning, which seem to similarly apply to monolingual and bilingual adult language learners.

主講人簡介

       Pedro Kepa Paz-Alonso is a Ramon y Cajal fellow and the head of the Language and Memory Control (LMC) research group, a multidisciplinary team including  cognitive neuroscientists, mathematicians and engineers. His research program uses functional and structural multimodal MRI techniques to investigate how higher cognitive functions result from interactions between different cognitive components, focusing mostly on language (reading, speech comprehension and production), attention and memory (semantic, episodic) across the life span in cognitively normal and clinical populations. He and his group also work on designing, developing and implementing new MRI methods. Kepa’s research experience includes 6 years of postdoctoral training in cognitive neuroscience and the use of advanced MRI techniques at international institutes such as the Center for Mind and Brain at the University of California (UC), Davis, and the Helen Wills Neuroscience Institute at UC Berkeley. He has an extensive network of national and international collaborators in different domains (i.e., cognitive neuroscience, network neuroscience, medical imaging and human neuroanatomy) with whom he conducts relevant multidisciplinary research projects and keep improving his scientific program. He has participated as PI, co-PI or collaborator in research projects funded by national (e.g., FIS, MICIN, MINECO, Basque Government, La Caixa Health Research) and international agencies (e.g., ERC, NSF).
