The Effects Of Sexual Orientation And Behavioral Style On Perceptions Of Men's Leadership Potential And Effectiveness, Kristin Elizabeth Mann

College of Science and Health Theses and Dissertations

This study addressed a gap in the industrial-organizational psychology research by investigating perceptions of LGBTQ leaders in the workplace. Specifically, it investigated the theory that gay men and heterosexual women experience similar scrutiny and resulting discrimination when in leadership roles. Participants were 363 psychology students who evaluated an applicant for a managerial position. Participants scored the candidate’s leadership potential (hirability) and effectiveness based upon his resume, biography, and short video interview. The candidate’s sexual orientation (gay, heterosexual, control) and behavioral style (agentic/masculine, communal/feminine) were manipulated, for a resulting 2 x 3 research design. By integrating gender and leadership theories with …

Role Of Gap Junctions In Seizures, Samuel Shin, Dr. Scott Steffensen

Journal of Undergraduate Research

Seizures are a disease that inflict millions with no reliable treatment or cure. One of the main difficulties behind treating seizures is the uncertainty behind the cause. In previous studies we performed we found that connexin-36 (Cx36) knockout (KO) mice may respond differently to stimuli that illicit seizures. From this we hoped to find evidence that gap junctions, specifically Cx36 in the hippocampus, played a role in seizures.

Understanding The Nature Of Anxiety In Autism, Sarah White, Dr. Mickle South

Journal of Undergraduate Research

Anxiety is extremely prevalent in autism, with estimates of the co-occurrence ranging up to 84%. Surprisingly, even though anxiety in autism is implicated in behavioral symptoms ranging from avoiding eye contact with others to always insisting on the same menu for lunch, the majority of research has ignored anxiety as a major contributor to the core symptoms associated with autism. Most research has focused on symptoms of social impairment, but it is now realized that anxiety may be a critical factor in the development of such symptoms.

Adolescents’ And Parents’ Perceptions Of Religious Pre- And Proscriptions, Ryan Woodbury, Dr. Sam Hardy

Journal of Undergraduate Research

As mentioned in my proposal, we sought to understand adolescents’ and parents’ perceptions of religious norms and how those norms predicted adolescents’ positive and negative behaviors. We asked six questions to help guide our research:

Memory Processes In Pregnant Women, Quentin Smith, Dr. Brock Kirwan

Journal of Undergraduate Research

Pregnancy is a complicated biological process that is often accompanied by reported cognitive changes among pregnant women. Pregnant women commonly report diminished cognitive functioning during pregnancy, with “forgetfulness” and “a poor memory” as the most common complaints (Brett & Baxendale, 2001; Crawley, 2002). However, despite these anecdotally reported deficits, the evidence suggesting memory impairments in pregnancy are equivocal. In a recent meta-analysis of 14 studies of memory in pregnancy, it was concluded that pregnancy disrupts some, but not all, memory processes (J. D. Henry & Rendell, 2007). In particular, memory tasks that place high demands on executive cognitive control seem …

Detection Of Social Threat In Autism Spectrum Disorders (Asd), Whitney Worsham, Dr. Michael Larson

Journal of Undergraduate Research

The purpose of this research project was to investigate underlying difficulties with social interaction in children with autism spectrum disorders (ASD). Previous research has demonstrated that children with ASD are inhibited in processing social cues, including social threat (Krysko & Rutherford, 2009). We hypothesized that children with autism spectrum disorders (ASD) would demonstrate decreased reaction times and error rates relative to typically-developing children when viewing social threat-related stimuli. We also hypothesized that, when viewing non-social threat-related stimuli with no social context, children with ASD would display intact performance relative to typically developing children. We tested these hypotheses through comparing the …

Dissociating The Influence Of Associations From That Of Interference In The Human Hippocampus, Rick Stone, Dr. Brock Kirwan

Journal of Undergraduate Research

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 been a result of higher interference, rather than higher associativity, so we tried to design an experiment to distinguish between the two.

Regrouping: Organized Activity Involvement And Social Adjustment Across The Transition To High School, Amy M. Bohnert, Julie Wargo Aikins, Nicole T. Arola

Psychology: Faculty Publications and Other Works

Although organized activities (OAs) have been established as important contexts of development, limited work has examined the role of OAs across the high school transition in buffering adolescents' social adjustment by providing opportunities for visibility and peer affiliation. The transition to high school is characterized by numerous changes and OAs may provide an important setting for establishing and maintaining peer relationships during this tumultuous time. This study included 151 8th grade U.S. students (58% male) who were assessed across the transition to high school (spring of 8th and 9th grade). Continuous involvement in academic activities across the transition and becoming …

Peak Of The Day Or The Daily Grind: Commuting And Subjective Well-Being, Oliver Blair Smith

Dissertations and Theses

To understand the impact of daily travel on personal and societal well-being, researchers are developing measurement techniques that go beyond satisfaction-based measures of travel. Metrics related Subjective Well-Being (SWB), defined as an evaluation of one's happiness or life satisfaction, are increasingly important for evaluating transportation and land-use policies. This dissertation examines commute well-being, a multi-item measure of how one feels about the commute to work, and how it is shaped. Data are from a web-based survey of workers (n=828) in Portland, Oregon, U.S.A., with three roughly equally sized groups based on mode: bike, transit and car users. Descriptive analysis shows …

Alternative Hospital Gift Bags And Breastfeeding Exclusivity, Yeon Bai, Shahla M. Wunderlich, Rickie Kashdan

Department of Nutrition and Food Studies Scholarship and Creative Works

The type of gift bags given to new mothers at the time of discharge from the hospital can influence their confidence in breastfeeding. Most hospitals in the US continue to distribute commercial gift bags containing formula samples despite the reported negative influence of commercial bags on the duration of breastfeeding. This study compared breastfeeding outcomes in women receiving three different kinds of gift bags at discharge. A prospective intervention study was conducted during the 2009-2010 in New Jersey. Three breastfeeding cohorts were recruited and assigned to three groups: COMMERCIAL received discharge bags containing formula samples, BF-INFO received breastfeeding information and …

Dynamic And Opposing Adjustment Of Movement Cancellation And Generation In An Oculomotor Countermanding Task., Brian D Corneil, Joshua C Cheng, Samanthi C Goonetilleke

Brain and Mind Institute Researchers' Publications

Adaptive adjustments of strategies help optimize behavior in a dynamic and uncertain world. Previous studies in the countermanding (or stop-signal) paradigm have detailed how reaction times (RTs) change with trial sequence, demonstrating adaptive control of movement generation. Comparatively little is known about the adaptive control of movement cancellation in the countermanding task, mainly because movement cancellation implies the absence of an outcome and estimates of movement cancellation require hundreds of trials. Here, we exploit a within-trial proxy of movement cancellation based on recordings of neck muscle activity while human subjects attempted to cancel large eye-head gaze shifts. On a subset …

Effects Of The Integrated Symple Readers Curriculum On Expressive Vocabulary Acquisition In Elementary Students With Developmental Disabilities, Loralene Edvalson

Theses and Dissertations

Despite the emphasis society places on literacy, most students with developmental disabilities remain illiterate. One cause for this illiteracy may be that these students lack foundational language skills that contribute to being able to read. Research has shown that, among other contributions, multiple exposures across time increase students' abilities to acquire knowledge. The Symple Readers integrated curriculum plans for multiple exposures to novel picture vocabulary words by building them into all activities across the students' day and week. The purpose of this study was to determine the effects of the Symple Readers integrated curriculum on expressive vocabulary development. During the …

The Development Of A Self-Report Questionnaire To Measure Problematic Video Game Play And Its Relationship To Other Psychological Phenomena, Anatol Tolchinsky

Master's Theses and Doctoral Dissertations

Problematic video game play is becoming a more frequent clinical presentation, and currently there is no standard way of measuring this phenomenon. This study operationalized this construct in a way that accurately reflects the existing literature and attempted to construct a valid measure based on this information. This new assessment instrument was evaluated by analyzing its factor structure on both 375 college-age participants and 314 online participants who endorsed being a regular video game player.

This area of research is still in its infancy, especially in regard to comorbid psychopathology. Consequently, this study surveyed participants’ subjective experience of depression and …

Boys Will Be Boys, Girls Will Be..., Rashida Aluko-Roberts

SURGE

Lets talk about sex.

Well not really, just the double standard that comes with the topic. It’s no secret that men and women are taught to think about sex differently. While there are many (myself included) who fail to accept these culturally imposed ideas and attitudes about sex, it would be incredibly naïve to not acknowledge the existence of the double standard that exists.

Evaluating A Social And Emotional Learning Curriculum, Strong Kids, Implemented School-Wide, Thomas Jonathan Kramer

Theses and Dissertations

The goal of this study was to explore whether Strong Kids could result in improved social and emotional competence when implemented as a school-wide universal intervention. No prior studies have examined this question. This study also evaluated whether teachers could implement Strong Kids as it was designed and whether they viewed it as socially valid. It used a non-equivalent control group design. The treatment school in the study involved 348 students and 17 teachers from a Title I school. School demographics indicated that 61% of students were Hispanic, 37% White, and 2% of other ethnicities. Approximately 82% of the students …

The Role Of Emotion In Environmental Decision Making, Hannah Dietrich

Department of Psychology: Dissertations, Theses, and Student Research

Given the environmental concerns of our planet, it is imperative to consider issues of environmental sustainability. Researchers argue that the most serious environmental problems are not merely issues of science, but that of individual behavior. Solutions, therefore, must consider the role of the individual—how one can change his/her behaviors to be more environmentally conscious. The experience of negative or positive emotions, may impact not only people’s experiences with the environment, but also their tendency to engage in pro-environmental behavior. The present study sought to experimentally investigate the role of emotion and information on pro-environmental behavior change. Results indicate that neither …

Law Enforcement And The Mentally Ill: Thirty Years Of Police Literature, Jennifer Noe

Publications and Research

This study applies the methodology of content analysis to 30 years of law-enforcement literature to determine whether online access to scholarly research in social work and mental health made a difference in police policy toward the mentally ill. Keywords from the controlled vocabulary of these fields were found in the body of content analyzed prior to easily accessible online resources in 1997 , yet the number of articles on the subject grew from approximately one per year prior to 1998 to nearly five per year by 2011. The imprint of these two fields from outside of law enforcement was discernible …

Psychotherapy Outcome For Eating Disorders: A Meta-Analysis, Julia Bryn Hubbard

Theses and Dissertations

The purpose of this project was to summarize psychotherapy outcomes for eating disorders using meta-analysis. Psychotherapy was defined as any psychosocial treatment including face-to-face therapy, self-help, and Internet approaches. All primary studies, meeting inclusion/exclusion criteria from 1980 to 2010, were included. Results suggested that individuals treated with active treatments demonstrate better outcomes than those in control conditions (d= 0.33, p <.01, 95% CI [0.19-0.46]). CBT was the most often occurring treatment in the primary studies and a small effect, favoring CBT, was found when the treatment was compared to all other active treatments (d = 0.16, p = .02, 95% CI [0.03-0.28]). Internet and self-help approaches continue to show promise with Internet treatments demonstrating superior outcomes to control conditions (d = 0.54, p <.01, 95% CI [0.19-0.90]). More research is needed to determine whether these approaches can suffice as stand-alone treatments or if they are best used in addition to already well-established approaches (i.e., individual CBT). The meta-analysis also explored whether treatment type, outcome measure, diagnosis, attrition, and diagnostic severity moderate treatment effect. Finally, the meta-analysis updated and improved upon previous meta-analyses by focusing on randomized controlled trials, including all diagnoses of eating disorder, only combining effect sizes from similar conditions, including all possible studies that meet inclusion criteria, computing and comparing effect sizes for outcome measures beyond those considered primary to eating disorder treatment, and also addressing outcomes for all brands of psychotherapy including traditional talk therapy, self-help, and Internet approaches.

Perception Of Maximum Stepping And Leaping Ability, Brian Michael Day

Theses and Dissertations

To successfully perform everyday behaviors, people must be able to perceive affordances.

Two general categories of affordances have been investigated: body-scaled affordances depend on geometric properties (e.g., arm length) and action-scaled affordances depend on dynamic properties (e.g., maximum running speed, body compressibility, etc.). The fact that these affordances depend on different kinds of relationships between animal and environment, suggests that body scaled affordances and action scaled affordances may be qualitatively different. We investigated this hypothesis by using a transfer of calibration paradigm. In particular, we investigated whether improvements in perception of maximum stepping distance (a body scaled affordance) transferred to …

Lost In The Margins? Intersections Between Disability And Other Non-Dominant Statuses With Regard To Peer Victimization And Psychosocial Distress Among Oregon Teens, Marjorie Grace Mcgee

Dissertations and Theses

Youth with disabilities experience greater levels of victimization than non-disabled youth. However, little is known about the associations between peer victimization and disability status alone and in combination with sex and race/ethnicity, or with sex and sexual orientation. Further, little is known about the extent to which exposure to peer victimization mediates the relationship between disability status and psychosocial distress. Thus, one purpose of this study was to investigate the extent to which disability status, as a marker of social difference, alone and in combination with other social identities, is associated with differential levels of exposure to peer victimization. A …

Adaptation To The U.S. And Religion/Spirituality: Experiences Of Indian International Students, Kirti Potkar

Theses and Dissertations

Religion and spirituality are deemed an important aspect of human diversity, found to be important to people, and have significant impact on different aspects of functioning. Given the rising numbers of international students on U.S. campuses, it becomes important to examine how religion/spirituality impacts their sojourn in the U.S. This study explored the religious/spiritual experiences of Indian international students here in the U.S. using a qualitative approach. Thirteen Indian international students pursuing graduate degrees in the U.S. were interviewed. The interviews were then transcribed and analyzed using a synthesis of hermeneutic methods informed by Kvale (1996). The following themes emerged …

Large-Scale Network Organization In The Avian Forebrain: A Connectivity Matrix And Theoretical Analysis, Verner Peter Bingman, Murray Shanahan, Toru Shimizu, Martin Wild, Onur Güntürkün

Psychology Faculty Publications

Many species of birds, including pigeons, possess demonstrable cognitive capacities, and some are capable of cognitive feats matching those of apes. Since mammalian cortex is laminar while the avian telencephalon is nucleated, it is natural to ask whether the brains of these two cognitively capable taxa, despite their apparent anatomical dissimilarities, might exhibit common principles of organization on some level. Complementing recent investigations of macro-scale brain connectivity in mammals, including humans and macaques, we here present the first large-scale "wiring diagram" for the forebrain of a bird. Using graph theory, we show that the pigeon telencephalon is organized along similar …

Loss Of Sustained Activity In The Ventromedial Prefrontal Cortex In Response To Repeated Stress In Individuals With Early-Life Emotional Abuse: Implications For Depression Vulnerability, Lihong Wang, Natalie Paul, Steven J. Stanton, Jeffrey M. Greeson, Moria J. Smoski

College of Science & Mathematics Departmental Research

Repeated psychosocial stress in early-life has significant impact on both behavior and neural function which, together, increase vulnerability to depression. However, neural mechanisms related to repeated stress remain unclear. We hypothesize that early-life stress may result in a reduced capacity for cognitive control in response to a repeated stressor, particularly in individuals who developed maladaptive emotional processing strategies, namely trait rumination. Individuals who encountered early-life stress but have adaptive emotional processing, namely trait mindfulness, may demonstrate an opposite pattern. Using a mental arithmetic task to induce mild stress and a mindful breathing task to induce a mindful state, we tested …

Overall Nasalance Versus Trimmed Selection Of Stable Syllable Repetition, Jackson Peebles

Honors Theses

Objective: To evaluate the difference between nasalance measured using overall nasalance for the full set of syllable repetitions in a speech sample contrasted with syllable repetitions selected (trimmed) from the overall sample.

Method: Participants included 24 males and 34 females between 18 and 30 years of age who participated in a normative study of nasalance in Michigan’s lower peninsula. Participants produced 14 syllable stimuli. Each syllable sequence was repeated at least 8 times. Three trials of each repetition were recorded together with other speech stimuli. Overall nasalance was calculated for each syllable repetition sequence (whole) and compared with the mean …

Work Design Characteristics As Moderators Of The Relationship Between Proactive Personality And Engagement, Damon Thomas Drown

Dissertations and Theses

This study examines which and how trait relevant work design characteristics moderate the relationship between proactive personality and engagement. Proactive personality is defined as an individual's tendency to intentionally and directly affect change in their environment (Bateman & Crant, 1993; Crant, 2000). Previous research has been primarily focused on the positive aspects of proactive personality; to fill this gap, I used trait activation theory (Tett & Burnett, 2003) to identify which work characteristics will activate proactive personality to affect engagement and developed specific hypotheses about which work characteristics will attenuate the proactive personality engagement relationship. In the study I identified …

Qeeg Correlates Of Cognitive Deficits In Multiple Sclerosis During Targeted Cognitive Tasks, Robert B. Frost

Theses and Dissertations

Multiple sclerosis (MS) is the most common neurological disorder of young adulthood and is often associated with cognitive impairment and emotional dysfunction. Due to the nature of the disease, the cognitive deficits in MS are often variable in their presentation, and consist of deficits in processing speed, attention, working memory, and executive functioning. The purpose of the present study was to explore common methods of documenting MS-related cognitive deficits, to elucidate the relationship between the cognitive deficits seen in MS and physiological markers of cognitive functioning (i.e., quantitative EEG), and to analyze the relationship between cognitive deficits and mood dysfunction …

Proactive Measures In Combating Bullying In Schools: Examining The Effectiveness Of The Bucket Fillers Program In Character Building Education, Karina Katsikis

Theses and Dissertations

Bullying continues to plague our schools. Some schools are implementing proactive solutions in the form of character building education to address bullying. The purpose of this research was to examine the character education program, Bucket Fillers, and its effectiveness on reducing bullying in one public elementary school by examining questionnaires containing homeroom teachers' evaluations. Data of behavioral incident reports from prior to the program's initiation and after were also collected and compared. The majority of teachers noticed more spontaneous positive interactions and less negative interactions between students after the establishment of the program. There was no significant correlation found between …

An Examination Of The Impact Of Hoarding Parent-Adult Child Relationships And Family Functioning, Jennifer M. Park

USF Tampa Graduate Theses and Dissertations

Compulsive hoarding is characterized by difficulty discarding unneeded items and the accumulation of items within living spaces and is associated with significant functional impairment and distress. Along with the negative impact on the individual, previous reports have indicated that compulsive hoarding is not only impairing and substantially burdensome for family members, but also linked to disruptions in family functioning. The present study utilized a path model analysis to examine the associations between an array of hoarding variables hypothesized to impact family functioning and parent-adult child relationships in 199 adult children of hoarders. Results revealed that family functioning mediated the relationship …
