Summary: 

Individuals value the ability to actively make decisions and manipulate their environment. While previous research has characterized the prioritization of valuable information in episodic memory (reviewed by Murty & Adcock, 2017), these processes have not been fully characterized in the context of decision-making. Across four studies, I will present behavioral and neuroimaging data showing how making arbitrary decision-making during encoding enhances episodic memory. In study 1, I will show that the simple act of making a decision enhances episodic memory, and that memory enhancements are related to choice-induced preference. In study 2, I will show that decision-related memory enhancements are associated with greater interactions between the striatum and hippocampus during encoding. Finally, in studies 3 & 4, I will show that decision-related memory enhancements are driven, in part, by mechanisms of memory consolidation. Together, these findings support a mechanism by which actively deciding to encode information preserves episodic memory for outcomes.
