Slovenian version of the Deese–Roediger–McDermott paradigm : a normative and exploratory study

Černe, Jaša (author), Kordeš, Urban (author)

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.

Abstract

Raziskave s paradigmo Deese–Roediger–McDermott (DRM) so zbrale številne dokaze za zanesljiv medkulturni učinek lažnega spomina. Toda svojo različico paradigme DRM in pripadajoče normativne podatke je prejel le omejen nabor jezikov. V tej študiji smo uporabili 728 udeležencev (594 žensk) za izdelavo prve slovenske različice paradigme DRM in dodatnih 90 udeležencev (66 žensk) za preizkus njene učinkovitosti pri induciranju lažnih spominov in izvedbo eksploratornih analiz. Smo prvi, ki smo normativno študijo DRM izvedli v celoti po spletu, in med redkimi, ki so poleg pogosto uporabljenih mer natančnosti merili reakcijske čase (RČ). Gledano v celoti so udeleženci priklicali 69 % besed s seznama in 14 % kritičnih besed ter dodatno prepoznali 79 % besed s seznama in 45 % kritičnih besed. Udeleženci so priklicali in prepoznali besede s seznama z enako hitrostjo kot kritične besede, za nepovezane besede pa so potrebovali znatno več časa. Študija kaže, da je lažne spomine mogoče učinkovito raziskovati s spletno obliko paradigme DRM. Prihodnje študije bi morale podrobneje raziskati razmerje med RČ in merami natančnosti, razmerje med priklicem in prepoznavo ter vpliv eksperimentalnega okolja na rezultate študij DRM. Upamo, da bodo predloženo gradivo in rezultati analiz prispevali k napredku raziskovanja lažnih spominov, zlasti v slovenskem jezikovnem okolju.
