Effects of Memorability on Mnemonic Discrimination
… developed a novel stimulus set and conducted two mnemonic discrimination experiments to tax hippocampal pattern separation, manipulating both image memorability and interference. These findings have important implications toward a better understanding of episodic memory and will provide an …

The Role of the Ventromedial Prefrontal Cortex in Mnemonic Discrimination and Generalization
… of retrieved memory traces. In this study, mnemonic discrimination and generalization were assessed in individuals with vmPFC lesions using the Mnemonic Similarity Task (MST; Stark et al., 2013), which was designed to assess the ability to distinguish previously learned images of everyday …

Cardiorespiratory fitness as a modulator of hippocampal subfield structure and function in cognitive aging
… and can be examined using behavioral mnemonic discrimination paradigms in humans. Age-related impairment in hippocampally-dependent cognition emphasizes the importance of identifying modulators of hippocampal plasticity. Critically, studies in older adults have demonstrated that …

Mismatch Negativity as a Marker of Auditory Pattern Separation Integrity in Aging
… interact with precision in memory (i.e., mnemonic discrimination) in aging? This study examined how the mismatch negativity (MMN), an electrophysiological marker of change detection and encoding, relates to age differences in mnemonic discrimination. The MMN was recorded from 33 young …

The impact of lifestyle factors and development on relational memory
… in a wide range of cognitive domains, including mnemonic discrimination and creativity. The work presented in this dissertation investigates the development of hippocampaldependent cognition and the sensitivity of these varied aspects of hippocampal function to health factors, using a …

Memory Fidelity in Healthy Ageing and Risk for Cognitive Decline
… in the fidelity or quality of perceptual and mnemonic representations. This thesis examined cognitive and neural underpinnings of individual differences in representational quality in healthy ageing and individuals at increased risk for cognitive decline to evaluate the potential of fidelity …

An Investigation into the Mechanisms Underlying Mnemonic Precision
Mnemonic precision refers to the degree of fidelity with which we represent the details of our past experiences. Maintaining a high level of mnemonic precision allows us to distinguish between similar experiential events. Across three chapters, this thesis examines how mnemonic precision declines …
