Özet:Adequate performances in daily life tasks require avoidance of attentional failures and enhanced cognitive control mechanism. Brain oscillations are claimed to have an effect on memory protection and suppression of distractive input. In this thesis, an effect of semantic interference suppression is investigated in an auditory working memory Sternberg paradigm. Semantic interference is created by Deese-Roediger-McDermott lists, adapted to Turkish. This study seeks an answer to whether the suppression of internal distractive mechanisms is performed in a way, similar to the inhibition of external distractors. Further, the study compares the resolution of interference in trials with semantic interference to the ones without it. Moreover, instances of cognitive failures, errors of false memory, are further compared with instances of successful resolution of semantic interference. We suggest that effective synchronization and desynchronization of upper alpha power during the stimulus free delay period is vital for successful performance on the task, failure to do so could lead to the formation of false memory errors.
