Reports an error in "Neural activity reveals interactions between episodic and semantic memory systems during retrieval" by Christoph T. Weidemann, James E. Kragel, Bradley C. Lega, Gregory A. Worrell, Michael R. Sperling, Ashwini D. Sharan, Barbara C. Jobst, Fatemeh Khadjevand, Kathryn A. Davis, Paul A. Wanda, Allison Kadel, Daniel S. Rizzuto and Michael J. Kahana (Journal of Experimental Psychology: General, 2019[Jan], Vol 148[1], 1-12). In this article, the second sentence in the second paragraph in the author note omitted additional grant information and should appear instead as follows: This work was supported by the DARPA Restoring Active Memory (RAM) program (Cooperative Agreement N66001-14-2-4032) and by the National Institutes of Health (Grant MH055687). (The following abstract of the original article appeared in record 2018-66881-001.) Whereas numerous findings support a distinction between episodic and semantic memory, it is now widely acknowledged that these two forms of memory interact during both encoding and retrieval. The precise nature of this interaction, however, remains poorly understood. To examine the role of semantic organization during episodic encoding and retrieval, we recorded intracranial encephalographic signals as 69 neurosurgical patients studied and subsequently recalled categorized and unrelated word lists. Applying multivariate classifiers to neural recordings, we were able to reliably predict encoding success, retrieval success, and temporal and categorical clustering during recall. By assessing how these classifiers generalized across list types, we identified specific retrieval processes that predicted recall of categorized lists and distinguished between recall transitions within and between category clusters. These results particularly implicate retrieval (rather than encoding) processes in the categorical organization of episodic memories. (PsycINFO Database Record (c) 2019 APA, all rights reserved)
