Dissociable Influence of Reward and Punishment Motivation on Declarative Memory Encoding and its Underlying Neurophysiology
… environment is represented in long-term memory. The present dissertation aims to delineate the influence of reward and punishment motivation on human declarative memory encoding and its underlying neural circuitry. Chapter 1 provides a theoretical framework for investigating motivation's …

Modeling False Memory in the Deese-Roediger-McDermott Paradigm: An Approach Using Holographic Declarative Memory
… which are required for predicting false memory. Conversely, hyperdimensional computing (HDM) approaches effectively capture semantic similarity but lack mechanisms for control processes (Reid & Jamieson, 2023; Dodhia & Metcalfe, 1999). We propose a Holographic Declarative Memory (HDM) …

Neuroimaging and behavioral investigation of declarative memory in South African children prenatally exposed to alcohol
… alcohol spectrum disorders (FASD). Although declarative memory impairment is a key feature of the neurocognitive profile of FASD, the mechanisms underlying this deficit require further clarification. The aim of this cross-sectional research was to examine, both directly and indirectly (via …

Continuity in the Absence of Declarative Memory in Patients with Moderate Dementia of the Alzheimer's Type
… advances into the understanding of implicit memory have opened up new possibilities of patient care. The ontology developed within the existentialphenomenological (EP) tradition provided the best foundation for further research in this direction, toward restoring moderately impaired DAT …

The role of declarative memory in the acquisition of conceptual semantic knowledge in Autism Spectrum Disorder
Based on Ullman’s (2004) hypothesis that declarative memory impairment will contribute to language impairment, this thesis presents two experiments that test familiarity and recollection in children with Autism Spectrum Disorder (ASD) and Intellectual Disability (ID). Four experimental groups …

Memory, Amnesia, and the Hippocampal System: The Time Course and Neural Substrates of Relational (Declarative) Memory
… these findings indicate that relational memory processes occur early and spontaneously, and are critically dependent upon the hippocampus, consistent with and extending the relational memory theory.

NREM sleep spindles and slow wave sleep in younger and elderly women: an investigation of their influence on declarative memory consolidation
… and sleep spindles play an essential role in declarative memory consolidation. However, this role is not well understood in the ageing women. With advancing age, SWS and sleep spindles undergo significant decreases in duration and density, while there is a simultaneous decline in declarative …

Comparing vector-based and ACT-R memory models using large-scale datasets: User-customized hashtag and tag prediction on Twitter and StackOverflow
… provides unique opportunities to study models of declarative memory. The tasks of choosing a hashtag for a tweet and tagging a post on StackOverflow were framed as declarative memory retrieval problems. Two state-of-the-art cognitively-plausible declarative memory models were evaluated on how …

A capacity limited, cognitive constructionist model of virtual presence
… processing paths between attention, working memory, declarative memory and procedural memory, which operate to create and maintain a semantic context or bias. Bottom-up information entering the sensory cortices is filtered by attention into working memory where it forms temporary structures …

Probabilistic category learning and memory systems functioning in those at-risk for alcohol abuse.
… functioning, especially difficulties in memory functioning. The goal of this study was to examine declarative and non-declarative memory functioning in high-risk drinking college students using the Weather Prediction Task (WPT). We recruited 20 high-risk and 44 low-risk participants. We …

Event-based prospective memory in fetal alcohol spectrum disorders
Learning and memory seem to be particularly vulnerable to the effects of heavy prenatal alcohol exposure. Previous research has, however, been limited to the study of retrospective memory (i.e., episodic or declarative memory) in children with a history of prenatal alcohol exposure. Recently, …

Associations between sleep and cognitive-affective functioning in Posttraumatic Stress Disorder
… significant effects on the processing of neutral declarative memory, emotional memory, and emotional reactivity. Research spanning multiple neuroscientific literatures demonstrates that healthy, uninterrupted sleep is critical for memory consolidation and emotional regulation, and that …

Effects of Stress, Sex Differences, and Cognitive Reserve on Cognitive Decline in Healthy Elderly Subjects
… clinically by impaired performance on tasks of declarative memory. The Social Readjustment Ratings Scale (SRRS) is an inventory of high intensity psychosocial stressors. This instrument has previously been used to help calculate risk of disease. Using measurements of stressful life events, it …

The relationship between sleep and memory in PTSD
… to the formation of memories. Successful memory consolidation during sleep is contingent on the presence of slowwave sleep (SWS), REM sleep and the successful transition of stages across the night. In PTSD, both sleep and memory processes are disrupted, but no previous study has examined …

Talker-specific adaptation: how listeners learn and use indexical information during speech processing
… information in the speech signal and the memory mechanisms that support this learning. In this dissertation, I present a series of seven experiments examining listeners’ on-line processing of a novel foreign accent and the contributions of the declarative memory system and sleep-dependent …

The Deconstruction of Reinforcement Learning in Human Substance Use Disorder
… in SUD. Next, I investigated the integrity of declarative and non-declarative memory systems in cocaine use disorder patients with a category learning task, as these systems are thought to complement reinforcement learning. I found that cocaine use disorder patients showed clear deficits in …

The relationship between elevated night-time Glucocorticoid activity and dreaming: a perspective on sleep-dependent memory consolidation
Background. The consolidation of episodic memory is particularly vulnerable to fluctuations in glucocorticoid levels, both during wakefulness and during sleep. Corticosteroid exposure is associated with changes in endogenous glucocorticoid activity, sleep disruption, episodic memory impairment, and …

Social influences on children's learning
… (SES) relates to hippocampal-prefrontal declarative memory, but not striatal-dependent procedural memory. Finally, in Chapter 5 I demonstrate that the neural correlates of fluid reasoning differ by SES, suggesting that positive brain development varies by early life environment. …

Investigating the Relationship Between Subjective Sleep Quality and Statistical Language Learning

The influence of the trait-like tendency to rely on declarative- or procedural- like memory systems on the development of habits and compulsive behaviours in the rat
… a multi-systems organisation of long-term memory in mammals, where different types of memory are underpinned by dissociable neural systems which can operate independently of one another. A key distinction in this regard is that between declarative memory and procedural memory, which differ …
