System-generated alerts are ubiquitous in personal computing and, with the proliferation of mobile devices, daily activity. While these interruptions provide timely information, research shows they come at a high cost in terms of increased stress and decreased productivity. This is due to dual-task interference (DTI), a cognitive limitation in which even simple tasks cannot be simultaneously performed without significant performance loss. Although previous research has examined how DTI impacts the performance of a primary task (the task that was interrupted), no research has examined the effect of DTI on the interrupting task. This is an important gap because in many …


Exploring The Effects Of Depression And Physical Activity On Pattern Separation Performance, Michelle I. Nash Jun 2015

Exploring The Effects Of Depression And Physical Activity On Pattern Separation Performance, Michelle I. Nash

Theses and Dissertations

Cognitive performance declines in depression and increases with physical activity. These changes may in part be due to changes in the level of neurogenesis (the generation and survival of adult-born neurons), which decreases with depression and increases with physical activity. Pattern separation (the formation of distinct neural representations of incoming information through orthogonalizing similar patterns of activation) has also been linked to neurogenesis. This project explores pattern separation within these two populations through three experiments.Experiment 1. Previous research has found impaired pattern separation among individuals with higher depression scores, but who have not been diagnosed with Major Depressive Disorder (MDD). …


Imaging And Behavioral Correlates Of The Anterior Cingulate In Pediatric Traumatic Brain Injury, Tricia L. Merkley Feb 2012

Imaging And Behavioral Correlates Of The Anterior Cingulate In Pediatric Traumatic Brain Injury, Tricia L. Merkley

Theses and Dissertations

The anterior cingulate has been implicated in a number of cognitive processes that are at risk following traumatic brain injury (TBI), such as executive function and emotional processing. While the cingulate is believed to play a role in the above-mentioned cognitive processes, the relative roles of gray and white matter in functional outcomes post-TBI are not fully understood. The current study investigated various quantifiable brain properties (e.g., cortical thickness and volume, volume of underlying white matter, and white matter integrity) of the caudal anterior cingulate (CAC) gyrus and their relationships with behavioral measures of cognitive control following pediatric TBI.
