Can we predict the creation of false recognitions from event-related brain potentials recorded during encoding?
The poster depicts the project of research on event-related brain potentials (ERPs) recorded during the creation of false recognitions of words. The magnitude of literature on this fi eld focuses on the stage of recognition when subjects decide whether or not given words were presented to them previously. Only two recent studies analyzed ERPs recorded during encoding when subjects mere try to remember visually presented words which subsequently lead to falsely recognize (or correctly reject) the corresponding associates. However, the results of these studies are inconsistent. Urbach et al. (2005) reported higher amplitude of LPC component (500–800 ms poststimulus) for words not eliciting false recognitions while Geng et al. (2007) reported higher amplitude of LPC component (500–640 ms poststimulus) for words eliciting false recognitions. The authors claim that these effects refl ect item-specifi c information encoding or associative encoding, respectively. However, it seems highly improbable that the same ERP component refl ects different cognitive processes. Therefore, the current project proposes framework for understanding that discrepancy, namely the Activation Monitoring Theory developed by Roediger et al. (2001). Moreover, the project points two factors that can infl uence the creation of false recognitions and their electrophysiological correlates during encoding: the associative strength of words and their presentation duration.
