PlosONE: The challenge of learning a new language in adulthood: Evidence from a multi-methodological neuroscientific approach

This data set for the publication "The challenge of learning a new language in adulthood: Evidence from a multi-methodological neuroscientific approach" in PlosONE (2021) comprises: EEG: Event-related brain potential data (single subjects, microvolt values, regions of interest) for both correctly identified and correctly and incorrectly identified (merged) pseudoword-picture pairings (PPP) for learned as well as new PPPs for time windows 650-800 and 800-1300 ms. fNIRS: oxy-Hb and deoxy-Hb data (single subjects, beta values, regions of interest) for both correctly identified and correctly and incorrectly identified (merged) pseudoword-picture pairings (PPP) for learned as well as new PPPs Behavioral data: Task Performance during the recognition experiment (reaction times for and percentage of correctly identified learned and new PPPs)
