In the Deese-Roediger-McDermott (DRM)illusion this phenomenon, called the mirror effect, occurs when participantsfocus on unique features of each of the words in the study list. In previousstudies, the pleasantness rating task, used to foster distinctive encoding,generated different patterns of results. The main aim of our research is toexamine under what circumstances this task can produce the mirror effect in theDRM paradigm, based on evidence from recognition accuracy and subjectiveretrieval experience. In Experiment 1, a standard version (word pleasantnessrating on a 5-point Likert-type scale) was used for comparison with two otherencoding conditions: shallow processing (vowel identification) and a readonlycontrol. The standard task, compared to the other conditions, increasedcorrect recognition, but did not reduce false recognition, and this result maybe affected by the number of lists presented for study. Therefore, in experiment2, to minimize the possible effect of the so-called retention size, the number ofstudied lists was reduced. In addition, the standard version was compared witha supposedly more item-specific version (participants rated the pleasantness ofwords while thinking of a single reason for this), also including the read-onlycontrol condition. In both versions of the pleasantness rating task, more correctrecognition is achieved compared to the control condition, with no differencesbetween the two versions. In the false recognition observed here, only thespecific pleasantness rating task achieved a reduction relative to the controlcondition. On the other hand, the subjective retrieval experience accompaniedcorrect and false recognition in the various study conditions. Although thestandard pleasantness rating task has been considered to perform item-specificprocessing, our results challenge that claim. Furthermore, we propose a possibleboundary condition of the standard task for the reduction of false recognitionin the DRM paradigm PB Frontiers Media YR 2024 FD 2024 LK http://hdl.handle.net/10347/34537 UL http://hdl.handle.net/10347/34537 LA eng NO Alvarez-Martinez A, Sampedro-Vizcaya MJ and Fernandez-Rey J (2024) Examining the effects of pleasantness ratings on correct and false recognition in the DRM paradigm: accuracy, recollection and familiarity estimates.
