Title:
Threat-related arousal disrupts memory cohesion

Abstract:
A long history of emotional memory research shows memory enhancements for arousing versus mundane information. The majority of this work has focused on memory accuracy, with less attention paid to the form and structure of memory. In this talk, I will provide evidence for a model by which threat-induced arousal biases memory away from hippocampal-based representations and towards cortical representations, resulting in decontextualized representations of our environment that over-represent salient information. In the first part of the talk, I will discuss my prior research detailing arousal-based biases in MTL engagement in the context of motivated memory. Then I will present new research from our lab extending this work into clinical and naturalistic domains.
