Memory updating after retrieval: when new information is false or correct

Abstract

ABSTRACT We conducted three experiments testing the malleability of memory in incorporating new information following retrieval. All experiments used associative lists typical of the DRM paradigm [Deese, J. (1959). On the prediction of occurrence of particular verbal intrusions in immediate recall. Journal of Experimental Psychology, 58(1), 17–22; Roediger, H. L., & McDermott, K. B. (1995). Creating false memories: Remembering words not presented in lists. Journal of Experimental Psychology: Learning, Memory, and Cognition, 21(4), 803–814]. This paradigm enabled the evaluation of the integration of false information and correct information with the original information. In Experiment 1, participants studied DRM lists, and in a later phase either retrieved or restudied the lists and were presented with never-presented critical lures. The results of Experiment 1 showed that compared to restudy, retrieval enhanced the integration of subsequent false information, as measured by later recall in a follow-up test. In Experiments 2 and 3, after initial study, participants retrieved or studied incorrect information and received corrective feedback. The results showed that retrieval led to more error correction than restudy, when feedback was presented immediately. In general, this research suggests retrieval facilitates incorporation of new, related information, regardless of whether it is false or correct.
