Cognitive offloading, defined as the externalization of information, is ubiquitous in everyday life. However, its influence on internal memory remains under debate, with findings ranging from detrimental effects (e.g., Sparrow et al., 2011, Science, 333, 776–778) to clear benefits (Eskritt & Ma, 2014, Memory & Cognition, 42, 237–246). The present study examines how note-taking—a common and active form of offloading—affects the encoding and later retrieval of offloaded material in an adapted concentration game. In a laboratory experiment (N = 132), participants completed five rounds of the game with distinct card sets. Half of the participants were instructed to take notes, whereas the others had to rely solely on internal memory. After a brief delay, all participants completed a free recall test, a picture recognition test, and a position recognition test. Participants in the note-taking condition recalled significantly more items in both the free recall and position recognition tests, whereas no differences emerged in picture recognition. These findings suggest that note-taking can enhance internal memory for conceptual and spatial information. Preliminary data from a second experiment (N = 139) further indicate that noting down meaningful units (words) leads to greater memory benefits than noting down less meaningful units (letters). In sum, the experiments indicate a positive impact of cognitive offloading on internal memory, which we attribute to deeper elaboration during encoding.
