The New Normal: Goodness Judgments Of Non-Invariant Speech, Julia R. Drouin May 2014

The New Normal: Goodness Judgments Of Non-Invariant Speech, Julia R. Drouin

Honors Scholar Theses

Previous research has found that perceptual learning, or normalizing the idiosyncratic phonemes of speech, causes a shift in speech sound category boundaries. The present study examined if perceptual learning was limited to the boundary or if also caused a shift in internal category structure. Seventeen individuals participated in three behavioral tasks to explicate this question. In the Lexical Decision task, participants were trained in either /s/-biasing or /ʃ/- biasing context. In the Goodness Judgment task, participants rated a continuum of sounds on perceived /s/ goodness using a designated scale. Finally, in the Phoneme Identification task, participants listened to the same …


Mode, Method, And Medium: The Affordance Of Online Tutorials In The Writing Center, Erik V. Holtz May 2014

Mode, Method, And Medium: The Affordance Of Online Tutorials In The Writing Center, Erik V. Holtz

Honors Scholar Theses

While the body of literature regarding online tutorials in the writing center is growing, researchers seem hesitant to fully endorse, or even commend, online writing tutorials. This seems appropriate for work in communication theory and human-computer interaction; working across a medium may be different, but this could create new and interesting ways of tutoring. This research reports on a comparative analysis of online and in-person tutoring at three different universities, focusing on tutor self-perceptions and on affordances, a concept drawn from systems engineering, human-computer interaction and ecological psychology. Unstructured interviewing is used to create a set of preliminary affordances of …


The Reversal Effects Of Curcumin, An Herbal Remedy, On The Impairments Induced By Vmat-2 Inhibitor Tetrabenazine, Emily Qian, Samantha E. Yohn May 2014

The Reversal Effects Of Curcumin, An Herbal Remedy, On The Impairments Induced By Vmat-2 Inhibitor Tetrabenazine, Emily Qian, Samantha E. Yohn

Honors Scholar Theses

Substantial evidence has shown that dopamine (DA), particularly in the nucleus accumbens (NAc), is involved in behavioral activation and effort-related processes, such as overcoming work related response costs. Interference with accumbens DA transmission through administration of the vesicular monoamine transportor-2 (VMAT-2) inhibitor tetrabenazine (TBZ) produces an alteration of response allocation in the concurrent FR5/chow choice procedure, biasing animals toward the lower effort alternative. It has been suggested that these drug-induced shifts in effort-related choice behavior seen in rodents are analogous to symptoms such as psychomotor retardation, anergia, and fatigue, which can be observed in people with depression and other related …


Motivations For Targeted School Violence: Examining The Influence Of Social Rejection And Violent Video Games On Aggression, Maxwell R. Christensen May 2014

Motivations For Targeted School Violence: Examining The Influence Of Social Rejection And Violent Video Games On Aggression, Maxwell R. Christensen

Honors Scholar Theses

This Thesis Project investigates putative causes for mass-casualty violence in America’s schools. Both popular and scientific literatures suggest a variety of factors to explain these events, including violence in media such as movies and video games, gun culture, social constructions of masculinity, as well as social isolation, rejection, and disaffection among youth. Whereas such factors are not present in every incidence of mass violence and have yet to be demonstrated as explicitly causal variables, significant evidence points to social rejection in the form of bullying experiences and consumption of violent media such as first-person-shooter video games as representing key driving …


Responding To Trauma: Help-Seeking Behavior And Posttraumatic Growth In A College Sample, Aaron J. Burrick May 2014

Responding To Trauma: Help-Seeking Behavior And Posttraumatic Growth In A College Sample, Aaron J. Burrick

Honors Scholar Theses

Research indicates that traumatic experiences can impact college students’ mental health, academic abilities, and relationships with peers. Trauma and associated symptoms of PTSD can lower students’ well-being and increase the risk of withdrawing from the university. Research also emphasizes the importance of psychological help-seeking as a way to experience posttraumatic growth. This study examines traumatic experiences, help-seeking attitudes, barriers, and behaviors, and posttraumatic growth in a sample of 168 undergraduate college students. Results indicated an overwhelming preference for informal help-seeking resources and the importance of traumatic severity in the decision to seek help. Additionally, female participants reported greater traumatic severity …


Co-Worry In Friendship Dyads, Michelle H. Goldstein May 2014

Co-Worry In Friendship Dyads, Michelle H. Goldstein

Honors Scholar Theses

Anxiety disorders increase in prevalence from childhood into adulthood. Although cognitive theories are prominent in the etiology and maintenance of anxiety, peer relationships are emerging as salient interpersonal risk factors. This study investigates the effects of specific interpersonal interchanges on anxiety symptoms in college students. 60 undergraduates attended the experiment with a same-sex best friend, and were randomly assigned to the co-worry or neutral conversation condition. Each person completed self-report measures of state anxiety, negative affect and positive affect prior to and following an 8-minute conversation about self-generated worry topics such as exams or neutral topics such as the weather. …


An Animal Model Of The Motivational Symptoms Of Depression: Testing The Antidepressant Desipramine On An Effort-Related Choice Task, Samantha L. Collins May 2014

An Animal Model Of The Motivational Symptoms Of Depression: Testing The Antidepressant Desipramine On An Effort-Related Choice Task, Samantha L. Collins

Honors Scholar Theses

Patients with depression, schizophrenia, and other related disorders often show effort-related motivational symptoms such as anergia, psychomotor slowing, lassitude, and fatigue. Several studies have indicated that dopamine (DA) within the nucleus accumbens (NAc) is involved in the regulation of effort-related behavior. Interference with NAc DA alters response allocation in effort related choice procedures, biasing animals towards the alterative that can be obtained with minimal effort. Previous studies have shown that administration of the vesicular monoamine transporter-2 (VMAT-2) inhibitor tetrabenazine (TBZ) shifts behavior in rats responding on the FR5/chow choice procedure causing a decrease in lever pressing and a compensatory increase …
