How the Organization of Autobiographical Memories Changes Over Time

Yoed N. Kenett, Alexa M. Tompary, Sharon L. Thompson-Schill University of Pennsylvania Autobiographical memories (AM) are often theorized as highly structured clusters of related events, but limited empirical research has examined how memories of our daily experiences are organized. Over consolidation, memories become less detailed, more integrated with prior knowledge stores, and more distributed across cortical regions. However, it is unclear how these changes affect the organization of these memories over time. Here, we apply computational network science methodologies to quantify the organization of recent (within the past year) and remote (5 – 10 years ago) AM and quantitatively examine how these networks change over time.
