Learning a new language involves developing the abilities to hear and produce new sounds and sound sequences. This project uses the methodology of linguistics, psychology, and neurophysiology to determine why some foreign language structures are mastered more easily than others. The goals are to determine whether language learners’ problems in pronunciation originate from errors of perception, and at what level of processing the perception errors occur. Two types of methodology are employed: discrimination tasks, in which listeners judge two stimuli as the same or different; and ERP (event related potentials), which measure automatic responses of the auditory system to changes in auditory stimuli.
