Slovenian Version of the Deese–Roediger–McDermott Paradigm: A Normative and Exploratory Study

Abstract

The research with the Deese–Roediger–McDermott (DRM) paradigm has accumulated substantial evidence for the reliable cross-cultural false memory effect. However, only a limited set of languages has had the benefit of receiving their own version of the DRM paradigm, let alone the corresponding normative data. In this study, we used 728 participants (594 women) to create the first Slovenian version of the DRM paradigm, and another 90 participants (66 women) to test its effectiveness in inducing false memories and conduct exploratory analyses. We are the first one to conduct a normative DRM study entirely online and among the few that measured reaction times (RTs) besides commonly employed accuracy measures. Overall, the participants recalled 69% of the list items and 14% of the critical lures, and additionally recognised 79% of the list items and 45% of the critical lures. The participants recalled and recognised list items as fast as critical lures and significantly faster than unrelated words. The study shows that false memories can be effectively explored by using the online format of the DRM paradigm. Future studies should investigate the relationship between RTs and accuracy measures, the relationship between recall and recognition, as well as the effects of the experimental environment on the results of the DRM studies in more detail. We hope that the provided material and its scrutiny will contribute to the progress in false memory research, especially in the Slovenian language environment.
