David Lassen and Dr. Christopher Karpowitz, Political Science Main Text Consumers of media during the past ten years have seen a dramatic shift in the way information is presented to the American public. With technical innovations associated with the Internet and the cultural adaptations that have accompanied them, modern American media has become increasingly interactive. […]

Experiences of Work/School/Family Conflict: A Qualitative Exploration
Sarah June Carroll and Dr. E. Jeffrey Hill, School of Family Life Introduction Most college students take on responsibilities and roles beyond full-time school work. Nearly three quarters of undergraduates work an average of 25.5 hours a week while attending school (NPSAS, as cited by Dundes & Marx, 2006). Between work and school, the working […]
High-Speed Full-Spectrum Interrogation of Fiber Bragg Gratings for Composite Impact Sensing
Spencer Chadderdon and Dr. Richard Selfridge, Electrical and Computer Engineering Fiber Bragg gratings (FBG) sensors are useful for static and dynamic event monitoring which make then suitable for a wide variety of applications. Dynamic interrogation of FBG sensors has primarily been performed using peak-tracking methods that have repetition rates approaching the megahertz range. However, tracking […]
Multiple Sclerosis and Brain Waves: Degree of Impact
Tyler Nickle and Dr. Ramona Hopkins, Department of Psychology Multiple sclerosis is a chronic inflammatory disease of the central nervous system. Studies show that 40-70% of individuals with MS have cognitive impairments in memory, executive functioning, attention, and processing speed (Rogers and Panegyres, 2007). Quantitative Electroencephalographic peak alpha frequency (PAF) is used to measure physiological […]
Brain Electrophysiological Source Localization of MMN & P300 Response in Auditory Processing
Amy Ragsdale and Dr. David McPherson, Department of Communication Disorders Source localization is a tool used to identify a precise visual location within the brain which allows for interpretation of the source of the brain activity. In this research, source localization is used to provide a more accurate identification and evaluation of the neurophysiological sources that contribute to […]
Endocannabinoid Biosynthetic Enzymes in Hippocampal Interneurons
Ryan Williamson and Dr. Jeff Edwards, Department of Physiology and Developmental Biology The hippocampus is a region of the brain that mediates learning and memory formation by changing the properties of synapses within its circuitry [2]. The plastic nature of these synapses allows the brain to alter how sensitive one neuron is to stimulation from […]
The Neuroprotective Effects of Exercise on LTD in the Hippocampus
Adam Field and Dr. Jeff Edwards, Department of Physiology and Developmental Biology In April of 2012, IACUC committee approved the methods which we had set forth for the carrying out of the experiment. At this point we began gathering the tools and materials needed for the performing of the experiment. Mice were obtained, and the […]
Dissociating the Influence of Associations from that of Interference in the Human Hippocampus
Rick Stone and Dr. Brock Kirwan, Department of Psychology This project has been worked on for nearly a year and a half. It began because research done by others indicated that there was greater hippocampal activity for an associative memory task than for a non-associative memory task. We believe that the greater hippocampal activity they observed may have […]
A Theory of Motivated Recall: Determinants of Recall of Political Information
Robert Richards and Dr. Christopher Karpowitz, Department of Political Science Background Research, Hypotheses A great deal of political research has analyzed how people form their opinions about candidates and issues. Two models, drawing heavily from cognitive psychology have emerged: the memory-based model (Zaller and Feldman 1992; Huckfeldt et al 1999) and the on-line model (Taber, […]
Negative Affect in Individuals with Moderate-to-Severe Traumatic Brain Injury: Implications for Acquiring New Learning
Spencer Liebel and Dr. Michael Larson, Department of Psychology The goal of this project was to clarify the additive role that negative affect plays in the capacity for individuals with moderate-to-severe (M/S) traumatic brain injury (TBI) to acquire new learning. Traumatic brain injury is the leading cause of death and disability in the United States, […]
