Oliver Johnston and Dr. Mikle South, Psychology Autism is a severe neurodevelopmental disorder with primary deficits in social communication. The purpose for this research was to investigate whether difficulties with empathy – the ability to feel what others feel – might contribute to the core social difficulties. This paper outlines the process used over the […]
Effects of Chronic Alcohol Intoxication on the Dopaminergic Reward Pathway
Brian Hoyt and Dr. Scott Steffensen, Psychology Department Overview of Project My research project studied the effects of chronic alcohol intoxication on the brain’s pleasure center (the mesocorticolimbic system). I worked with JungJae Park (M.S. in neuroscience) and three other undergraduate students. Because rats dislike the taste of alcohol, we injected the alcohol directly into […]
Effects of Mood on Error Processing
Alexander Gray and Dr. Michael Larson, Psychology Department Main Text This study will help us to better understand the neurophysiological correlates of error processing–the cognitive function of detecting mistakes. Also, this study will help clarify the potential generation process of this neurophysiological correlate, specifically called the error-related negativity (ERN). The ERN is a scalp-recorded, negative […]
Moral Conceptions and Parent-Adolescent Congruence: What Does it Mean to be a Moral Person?
Ryan James Funk and Dr. Sam Hardy, Psychology Department When I began working with Dr. Sam Hardy, I started in a simple data entry position. I would spend ten hours a week entering responses to survey questions into a computer program. As I spent more and more time in Sam’s lab doing data entry, I […]
Defining and Measuring Infant Habituation
Denise Free and Dr. Ross Flom, Department of Psychology Although we arguably know very little about the actual process of infant habituation, in assessing infant conditioning, controlled habituation is the procedure used most often. It may be that how infants habituate could vary as a function of their age. In addition a perceived “inability” at […]
Effects of Acute Ethanol on GABA Neuron Synaptic Responses
Kyle Ellefsen and Dr. Scott Steffensen, Psychology The nucleus accumbens is a midbrain structure which is thought to influence pleasure and reward. The physiology of this area is also thought to be altered in a state of addiction, including alcoholism. The nucleus accumbens receives most of its dopaminergic input from another midbrain structure, the ventral […]
An Evaluation of the Clinical Use of Phenytoin for Preventing Early Post-Traumatic Seizures in Traumatic Brain Injury Patients
Sierra Debenham and Dr. Erin Bigler, Psychology Main Text I evaluated the Montreal General Hospital’s use of the anti-seizure medication phenytoin in all traumatic brain injury (TBI) patients admitted to the hospital over the course of 2 years. I then evaluated the information to evaluate how effective the phenytoin treatment was in preventing early TBI. […]
Tantruming and talking: Measuring Treatment Outcome in Preschool Autism Treatment Programs
Jaime Ballard and Dr. Mikle South, Psychology Main Text One in every 133 children in Utah has autism, a disorder characterized by poor social and communication skills (U.S. Autism Rate Soars Twentyfold in 20 Years, 2007). These rates are climbing across the nation. As more children are born with these disorders, schools and other educational […]
The Influence of Positive Affect on Working Memory
Brenna S. Adams and Dr. Michael J. Larson, Psychology Department Main Text Positive affect, or positive emotion, is associated with improvements in most cognitive abilities, such as creative problem solving (Isen, Daubman, & Nowicki, 1987), the integration of information for strategic decision-making (Estrada, Isen, & Young, 1997), and verbal fluency (Phillips, Bull, Adams, & Fraser, […]
Learning to Change in Autism
Tiffani Newton and Dr. Mikle South, Department of Psychology Background The autism spectrum disorders (ASD) include a collection of severe neurodevelopmental symptoms related to social interaction and communication. In addition to these core symptoms, co-occurring anxiety is seen in up to 70% of diagnosed individuals (Reaven, 2010). Anxiety-inducing situations for ASD individuals include changes to […]
