Abstract:
|
|
To investigate the influence of proficiency level on the cortical organization of foreign language processing, two groups of German speaking students, differing only in their proficiency in English as a second language, were subjected to EEG coherence analysis during foreign and native language processing (news reports, frequency spectrum investigated: 1 – 32 Hz). In the group with minor experience with English, coherence increase was observed with all electrode combinations, with left hemisphere (LH) predominance. In the high proficiency group, coherence increase was limited to temporal electrodes over LH. Only in the latter group, coherence between prefrontal electrodes was significantly lower during the language tasks than during the baseline task (silence, noisy screen). Both results were obtained with foreign as well as native language processing. We suggest that reduced EEG coherence in language experts reflects a more efficient operating strategy not only for their second, but also for their native language.
Key words
