Duff, M.C., & Kurczek, J. (2013, April). Hippocampal amnesia disrupts episodic memory and narrative construction. <i>Poster presentation at the Cognitive Neuroscience Society Conference</i>, San Francisco, CA.<div> <div> <div> <div> <p><br></p><p>• Hallmark processing features of the hippocampus include its relational binding and representational flexibility (Eichenbaum & Cohen, 2001). Recent findings demonstrate that these same processes are engaged on-line in service of supporting behavior in the moment (Hannula & Ranganath, 2008 Barense et al., 2007; Warren et al., 2011). </p> <p>• This functionality of the hippocampus has been linked to cognitive abilities beyond its traditional role in long-term declarative (relational) memory including language. Duff and Brown-Schmidt (2012) have proposed that the functionality of the hippocampus positions it as a key contributor to language use and processing. Indeed, patients with hippocampal damage have a variety of deficits in the flexible and creative use of language and in the on-line processing of language (Duff & Brown-Schmidt, 2012). </p> <p>• An on-going debate is the whether deficits in the production of narrative elements, across either personal stories or picture descriptions/narratives, represent solely an impairment in memory (Race et al., 2011; 2013) or a more basic impairment in cognitive functioning outside of memory (Gasser et al., 2011; Zeman et al., 2012). </p> <p>• Here, we examine narrative in patients with hippocampal amnesia and analyze their narrative productions using methods from both the memory and language literatures. Based on our proposal about the role of hippocampus in language use, including narratives, we predict that hippocampal damage and relational memory impairment will disrupt narrative production across a variety of memory and language measures. </p> </div> </div> </div> </div>
