Özet (Çeviri)
A false memory experiment depends on the Deese-Roediger-McDermott (DRM) paradigm have designed using electroencephalography (EEG) neuroimaging technique to investigate differences between false and real memories in terms of neuronal activity. The work of Duzel et al. (1997) formed the basis of this study, consisting of two phases concerning study and recognition. In the study phase, semantically related words were presented. Some semantically associated words were not presented in the study phase, whereas they were served as false target items in the recognition phase. The subjects were asked to decide for each word whether these words were present or absent on the study phase (old/ new response) and whether they remember or know (R/ K judgment) that it was decided for every old response. Subsequently, a continuous confidence scale was used to measure subjects' confidence. The results show that false target items were judged old at nearly the same level as true target (studied) words. The false target items were recognized as remember in almost identical proportions with true target items. The subjects were highly confident that false target words had been shown in the study phase. We recorded ERPs while subjects made old/ new responses about previously seen words. Similarly, earlier studies found that old/ new effect was explained with three different ERP effects: FN400, parietal effects and late frontal. FN400 component was associated with familiarity of words (new>old), whereas parietal effect was related to recollection (old>new). For the late frontal effect, old items were more positive than news. The implications about false memory studies are discussed.
