The Nature of Visual Memory Representations
… of relational information maintained in on-line memory representations on subsequent processing of scenes, just as do younger subjects. These findings support the argument that verbal reports may not provide a complete picture of the information maintained in memory and may be confounded by …

Perception and Action Weighting in Memory Representations
… action, focusing on how this might occur under memory conditions. This was done in line with the proposals of grounded cognition and situated action, in which action and perception are tightly linked, and able to influence one another in order to aid the performance of a task. Following this …

Contributions of Signal-detection Mechanisms and Semantic Memory Representations to Famous Name Recognition
… investigators have often used the recognition memory paradigm to study the cognitive and neural processes that permit the ability to accurately assess whether or not stimuli are familiar. This paradigm involves presenting stimuli to participants in a study phase, and examining their later …

On the flexible nature of the relationship between attention and active memory representations
… psychology, our understanding of how active memory representations interact with attention remains highly contentious. One of the primary reasons for this continued debate has been a reliance on artificially dichotomizing the roles these systems play and ignoring the role of task demands …

Sensitivity of relational memory representations to the factors of repetition, emotion, and context information
Episodic memory is the human cognitive faculty that enables humans to have a record of everyday events. Relational processing and representations are widely accepted to be the crucial underlying mechanism, implemented in the hippocampus, that support normal episodic memory function. As such, to …

Structured representations in visual working memory
… to quantify the capacity of visual working memory by focusing on how many individual objects or visual features can be actively maintained in memory. This thesis presents a novel theoretical framework for understanding working memory capacity, suggesting that our memory representations are …

The role of sleep in consolidation of multi-item bound representations
… of literature has demonstrated that in terms of memory representations, items are not encoded equally. In part this has been suggested to be affected by conceptual knowledge, with items with pre-existing conceptual knowledge easier to encode and thus, more salient in subsequent representations. …

Medial temporal lobe and prefrontal cortex contributions to memory expressed on short timescales
Oftentimes, adaptive behavior relies on using memory for past events to guide upcoming decisions. To achieve this, memory structures in the brain interact with structures that exert cognitive control over the expression of such memories. This thesis investigated such interactions – the use of …

The role of recursive remindings on memory updating of emotional stimuli
… that the remindings embedded in emotional memory representations are stronger than neutral remindings (as supported by a preliminary experiment) and therefore attract attention internally during re-presentation, resulting in less attention toward the external stimulus and thus poorer …

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 …

Updating of representations in working memory
The limited capacity of working memory forces people to update its contents continuously. Two aspects of the updating process were investigated in the present experimental series. The first series concerned the question if it is possible to update several representations in parallel. Similar …

Age Group Differences In Recall of Relevant and Irrelevant Words
… that older adults tend to perform more poorly on memory tasks, when compared to younger people. Conversely, studies have also indicated that there may be ways to combat this decline in age related memory performance by using memory aid techniques. In addition to memory aid techniques, word …

Statistically learned visual representations support visual working memory
… concepts used by the VSL and visual working memory (VWM) literatures, I seek evidence that memory representations formed by VSL could support subsequent VWM performance, by employing the same regularities between tasks. In a series of experiments, I examined the extent to which …

Memory and locality in natural language
… constraints. I argue that under short-term memory constraints, optimal languages should exhibit information locality: words that depend on each other, both in their interpretation and in their statistical distribution, should be close to each other in linear order. The informationtheoretic …

Content representation in the human medial temporal lobe
The transformation of sensory inputs into complex memory representations is fundamental to human experience; yet, little is known about how this crucial process is achieved. When you meet your friend at the new cafe in town, what part of the brain encodes this novel scene into long term memory? …

Anteromedial Thalamus Gates the Selection & Stabilization of Long-Term Memories
… of systems consolidation, it is thought that the memory trace eventually reorganizes from the hippocampus to a distributed cortical network, with the anterior cingulate cortex playing a central role in remote memory retrieval. However, little is known about the mechanisms responsible for …

Negotiated Tutoring: An Approach to Interaction in Intelligent Tutoring Systems
… the high-level decision-making processes and memory representations used by a participant in dialogue. Dialogue generation is controlled by reasoning mechanisms which operate on a 'dialogue state', consisting of conversants' beliefs, a set of possible dialogue moves, and a restricted …

The accessibility of memory items in children’s working memory
… and systems that support recall in working memory. In particular it seeks to apply ideas from the adult-based dual-memory framework (Unsworth & Engle, 2007b) that claims primary memory and secondary memory are independent contributors to working memory capacity. These two memory systems are …

Prior knowledge and age effects in memory: Implications for episodic and short-term/immediate memory
