EEG ERP inhibitory response of selective attention in bilingual subjects

This bachelor thesis continues in research of bilingual subjects and investigates differences in cognitive functions (especially selective attention). It compares speed and accuracy of bilingual and monolingual responses on verbal stimuli (font detection) during which are observed subjects affected by tone with acoustic pressure of 76 dB. In theoretical part of the thesis I elaborated information about language and speech in general, language development, bilingualism, electroencephalography and of course about speech in neuropsychology. In empirical part there is described research methodology, elaboration and analysis of data, which was gained during the experiment. It?s assumed that bilingual subjects should have different values of event-related potentials, especially in linguistic part of the brain and according to behavioral data should show their cognitive advantage in less error rate. Two types of data were obtained from the experiment ? behavioral and EEG records. Behavioral data were processed in Excel and EEG records in the MATLAB programming environment. The results confirmed intergroup differences in ERP components, but these results were inconsistent within behavioral data, which can be attributed primarily to sample size
