Understanding Task Interference In Prospective Memory Using On-Line Probes: Strategic Delay Or Limited-Capacity Monitoring?, Francis T. Anderson
Understanding Task Interference In Prospective Memory Using On-Line Probes: Strategic Delay Or Limited-Capacity Monitoring?, Francis T. Anderson
Arts & Sciences Electronic Theses and Dissertations
In prospective memory (PM) research, a common finding is that people are generally slower to respond to a given ongoing task (OT) when they have to perform a PM task concurrently, as compared to performing the OT alone. Multiprocess theory claims that this slowing, termed task interference, is indicative of monitoring processes. Monitoring is thought to be cognitively demanding and heavily reliant on working memory, as people hold their intention in mind and look for features relevant to the PM task. PM decision control (PMDC) theory, instead, proposes that task interference reflects a strategic and intentional delay strategy. To address …

Exploring Usage Of Web Resources Through A Model Of Api Learning, Finn Voichick
McKelvey School of Engineering Theses & Dissertations
Application programming interfaces (APIs) are essential to modern software development, and new APIs are frequently being produced. Consequently, software developers must regularly learn new APIs, which they typically do on the job from online resources rather than in a formal educational context. The Kelleher–Ichinco COIL model, an acronym for “Collection and Organization of Information for Learning,” was recently developed to model the entire API learning process, drawing from information foraging theory, cognitive load theory, and external memory research. We ran an exploratory empirical user study in which participants performed a programming task using the React API with the goal of …

Transdiagnostic Multimodal Neural Correlates Of Psychosis Dimensions, Dov Bernard Lerman-Sinkoff
McKelvey School of Engineering Theses & Dissertations
Psychosis refers to a debilitating set of symptoms that impacts individuals, their communities, and society at large. Current psychiatric nosology treats psychosis as a categorical construct. However, recent evidence suggests that a dimensional approach that cuts across extant nosological boundaries may more accurately represent the underlying phenomena contributing to dysfunction in psychosis. One putative domain of transdiagnostic variation is cognitive control, a construct that refers to the set of functions that enable and support goal-directed behavior and regulation of one’s thoughts and actions. Previous analyses in both healthy individuals and individuals with psychosis have led to a number of findings …
Neural Mechanisms Of Cognitive Individual Difference: An Investigation Of The Human Connectome Project, Shelly Renee Cooper
Neural Mechanisms Of Cognitive Individual Difference: An Investigation Of The Human Connectome Project, Shelly Renee Cooper
Arts & Sciences Electronic Theses and Dissertations
Considering individual differences in task activation functional magnetic resonance imaging (t-fMRI) can be challenging because they may arise from variability in activity in brain regions, in the tasks themselves, or some combination thereof. Delineating sources of between-subjects variance is particularly important for cognitive control where task goals are at the forefront. Here we applied structural equation modeling (SEM) to the Human Connectome Project to examine if activity could be partitioned into separable brain and task individual difference dimensions. A series of SEMs were defined with varying numbers of latent factors, where the inputs were parcels of two cognitive control-related brain …
Quality Of Sleep, Stress, And Exercise: Effects Of Environmental And Lifestyle Factors On Spatial Navigation In Older Adults, Hannah Maybrier
Quality Of Sleep, Stress, And Exercise: Effects Of Environmental And Lifestyle Factors On Spatial Navigation In Older Adults, Hannah Maybrier
Arts & Sciences Electronic Theses and Dissertations
Introduction: With increasing age, many adults experience reduced spatial navigation ability, with the most prominent reductions in tasks dependent on the hippocampus. Hippocampal dysfunction may be linked to age-related increases in sleep fragmentation, which results in reduced neurogenesis and long-term potentiation. This project aims to determine if age-related reductions in hippocampal-dependent navigation ability and strategy selection are mediated by impaired sleep. Further, we propose that the effects of sleep on navigation are moderated by psychological stress and physical activity. Methods: 36 older (m: 70, sd: 7) and 33 younger (m: 20, sd: 1.5) adults recorded one week of sleep via …

About Face: Seeing The Talker Improves Spoken Word Recognition But Increases Listening Effort, Violet Brown
Arts & Sciences Electronic Theses and Dissertations
It is widely accepted that seeing a talker improves a listener’s ability to understand what a talker is saying in background noise (e.g., Erber, 1969; Sumby & Pollack, 1954). The literature is mixed, however, regarding the influence of the visual modality on the listening effort required to recognize speech (e.g., Fraser, Gagné, Alepins, & Dubois, 2010; Sommers & Phelps, 2016). Here, we present data showing that even when the visual modality robustly benefits recognition, processing audiovisual speech can still result in greater cognitive load than processing speech in the auditory modality alone. We show using a dual-task paradigm …
