Encoding and Test Interaction in the DRM Paradigm

Karely Rodriguez Jimenez

Senior, Psychology


A recent study by Ulatowska et al. (2020) showed that using a 2FC test resulted in fewer semantic memory errors as compared to a traditional yes/no test in the DRM paradigm (Deese, 1959; Roediger & McDermott, 1995). [RU1] The researchers attributed this difference to a possible enhanced source monitoring at the time of retrieval while performing a 2FC test. In this study, participants were instructed to memorize semantically related words either at a shallow or deep level and later to perform a 2FC or yes/no test. The results supported previous findings that the 2FC test resulted in fewer semantic errors, however, only following deep encoding. Shallow encoding demonstrated no difference in errors rates between the two tests. The memory rate for studied items was higher when the 2FC test was applied following both types of encoding. The results will be discussed in the framework of source monitoring as well as familiarity and recollection.

    Hi Karely. This is really fascinating and cool research. I think I could use what I’ve learned here to make exams harder. Seriously though, very impressive. I’m so proud of you!
