Neurobiological mechanisms underlying episodic memory retrieval
Memory is a central function of the brain and is essential to everyday life. Memory disorders range from those of memory transience, such as Alzheimer's disease, to those of memory persistence, such as post-traumatic stress disorder. To treat memory disorders, a thorough understanding of memory …

The Effects of Memory Retrieval Conflict on the Construction of a Deception
… was to examine the impact that long-term memory representations have on the ability to construct a deception. Twenty-five adults (18-40) were given a misinformation task originally used by Okado and Stark (2005), and then asked to alternate between responding deceptively and truthfully to …

Cognitive and neural correlates of memory retrieval in young and older adults
… the hypothesis that increased left-lateralized retrieval activity in older adults supports recollection attempt. Age deficits in semantic memory are more subtle than in episodic memory. However, older adults are impaired when automatic, data-driven processes are not sufficient to support the …

The Effects of Aging on Associative Learning and Memory Retrieval in Causal Judgment
… relationships requires associative learning and memory. Retrospective revaluation of causal cues requires associative memory (Aitken, Larkin, & Dickinson, 2001) to bind multiple cues together and use these associations to retrieve unseen cues for revaluation of their associative value. The …

Providing effective memory retrieval cues through automatic structuring and augmentation of a lifelog of images
… neurodegenerative conditions recall events from memory, to the maintenance and augmentation of extensive image collections of a tourist's trips. However, a large lifelog of images can quickly amass, with an average of 700,000 images captured each year, using a device such as the SenseCam. We …

Electrophysiological studies of identifying and modulating the preparatory strategic processes involved in episodic memory retrieval
Successful retrieval of episodic memories has been shown to depend on the overlap between the processes engaged during encoding and those re-engaged during retrieval. The ability to strategically adapt cue processing to maximize this overlap, sometimes referred to as “retrieval orientation”, has …

Shedding light on memory retrieval: reactivation of related information and its association with the hippocampus
Memory retrieval is a multifaceted process that involves the coordination of multiple areas of the brain including the cortical memory stores and the hippocampus, an area of the brain shown to be necessary for creating and using flexible bindings between items in memory. One phenomenon that has …

Examining the Impact of Guided Memory Retrieval on Intrusive Memories: An Online Trauma Film Paradigm Study
… problems (e.g., Brewin et al., 2010). Post-event memory processing may be a key facilitator of remission of intrusive memories (Marks et al., 2018). Contextual processing has been proposed to decrease unwanted distressing memories (e.g., Besnard & Sahay, 2016). In this study (N = 87), participants …

EXAMINING THE INFLUENCE OF TIME AND REPETITION ON RECENT AND REMOTE AUTOBIOGRAPHICAL MEMORY RETRIEVAL USING fMRI
… the prediction made by MTT that hippocampal memory traces expand and strengthen as a function of repeated memory retrievals. An fMRI paradigm was used to compare the effect of memory retrieval versus the mere passage of time on hippocampal activation. Participants retrieved remote …

The Role of Expertise, Working Memory Capacity, and Long -Term Memory Retrieval Structure in Situation Awareness
… the nature of individual differences in working memory and their roles in performing a flight situation awareness (SA) task. The major research question was whether the locus of individual differences in SA performance was the individual differences in capacity to maintain presented information …

Typical PM targets are not typically better than atypical PM targets: Underlying mechanisms of Prospective Memory retrieval

Is cue-based memory retrieval 'good-enough'?: Agreement, comprehension, and implicit prosody in native and bilingual speakers of English
… three critical components: a cognitive model of memory retrieval, a processing paradigm that outlines how resources may be deployed online, and the role of factors such as prosody in parsing decisions. </p> <p>The general framework of this integrated 'Good-enough Cue' (GC) model assumes the …

A psychological analysis of the effects of memory retrieval prior to extinction on the reacquisition of a conditioned fear association
… and determining whether prediction error at retrieval is necessary for the effect to occur. Following on from these studies, the next chapter presents three experiments which investigate whether trial spacing effects could explain the enhanced extinction and highlights conditions under which …

Combining Attentional Control and Semantic Memory Retrieval: A Sensitive Marker for Early Stage AD and AD-related Biomarkers in Healthy Older Adults
… measures of attentional control and semantic memory retrieval are sensitive markers of Alzheimer disease: AD). The present study examined the utility of combining measures of attentional control and semantic retrieval within a single task to discriminate healthy aging from early stage AD and …

Effects of healthy ageing on the precision of episodic memory
Episodic memory decline is one of the hallmarks of human cognitive ageing, but our understanding of the neurocognitive mechanisms underlying this decline remains limited. In particular, it is unclear whether healthy ageing differentially affects distinct components of episodic memory retrieval; …

Personal long-term memory aids
… documentation can be used to help remedy common memory problems. Assuming a long-term personal archive exists, when confronted with a memory problem, one faces a new challenge, that of finding relevant memory triggers. This dissertation examines the use of information-retrieval technologies on …

How does context variability affect representational pattern similarity to support subsequent item memory?
… and are commonly called "representations" or "memory traces". Existing studies indicate that information about the neural signal corresponding to a memory representation can be found in functional magnetic resonance imaging (fMRI) data when the pattern across its smallest units (voxels, often …

Aversive Olfactory Imprinting in Caenorhabditis Elegans
… to pathogenic bacteria can generate an aversive memory of bacterial odors that is sustained into adulthood (4 days), in contrast to training of adults that results in a medium-term memory that lasts for less than a day. This long lasting aversive memory is specific to the experienced pathogen and …
