Behavioral And Neural Correlates Of Episodic Memory Regulation, Mrinmayi Kulkarni
Behavioral And Neural Correlates Of Episodic Memory Regulation, Mrinmayi Kulkarni
Theses and Dissertations
Episodic memory retrieval, while critical for daily living, needs to be regulated to maintain goal-directed behavior. Past work has shown that episodic memory regulation engages brain regions involved in cognitive control, such as the dorsolateral and ventrolateral prefrontal cortex. These regions interact with the medial temporal lobe structures to control retrieval processes. In the current study, I paired eye-tracking, a sensitive index of memory, with fMRI in a novel paradigm to address several open questions in the field of episodic memory regulation. Participants initially encoded three celebrity faces and three tools with multiple indoor and outdoor scenes. In a subsequent …
Effect Of Schematic Congruence On Mnemonic Discrimination In The Hippocampal Subregions, Ariana M. Hedges-Muncy
Effect Of Schematic Congruence On Mnemonic Discrimination In The Hippocampal Subregions, Ariana M. Hedges-Muncy
Theses and Dissertations
Two experiments are presented in this dissertation to investigate the effect a schema may have on mnemonic discrimination. We developed stimuli composed of a foreground item on a background that was either schematically congruent or incongruent. For the encoding phase of both experiments, these stimuli were presented to 98 participants, who were tasked with determining the congruency of each foreground-background pair. Next, the two experiments diverged for the retrieval phase, where participants were presented with either the same object as before (Target) or one that was similar (Lure). Forty-six participants in Experiment 1 saw stimuli with the same background as …
