The Relationship Between Neuroticism, Self-Esteem, And Disordered Eating Attitudes: Examining The Health At Every Size Theory, Liana Cho

Masters Theses

Background. In the modern day treatment of overweight/obesity, conflicting recommendations regarding treatment have been released by the Academy of Nutrition and Dietetics (AND) and advocates of the Health at Every Size (HAES) movement. While the AND have indicated their support for self-monitoring practices, such as keeping a food diary or tracking calories, HAES advocates have claimed that these restrictive practices may result in increased disordered eating tendencies and poor self-esteem.

Subjects. The participants for this study included 410 students at Grand Valley State University. Almost 80% of participants were female, and just over 85% of participants identified as white. …

The Passive Effects Of Full-Gateway, In-Street Signs On Vehicular Speed, De'lon Dixon

Masters Theses

Reducing motorist’s speed when approaching crosswalks is an important goal in reducing the number of collision between motorist and pedestrian in crosswalks. The current study addresses this goal. The effect of gateway installation of in-street signs (one in-street sign installed between the two travel lanes in each direction and one on both edges of the roadway in each direction) on vehicle speed was evaluated on nine roads. The results demonstrated that the Gateway in-street sign treatment produced large speed reductions as vehicles approached the crosswalk and at the crosswalk. The average speed reduction was 3.8 mph at the crosswalk and …

The Spark Of Recovery: Artistic Methods That Generate Dialogue And Reduce Stigma In Families Affected By Mood Disorders, Adara Jensen

Masters Theses

Mood disorders, such as major depression and bipolar disorder negatively affect family dynamics, often resulting in trauma, antipathy, mistrust, and the breakdown in communication between the individual suffering from mood disorder and members of his or her family. The impact of mood disorder on family members impedes recovery for the person suffering from the disorder as well as the health and well-being of the family as a whole. Even emotionally healthy families suffer from the subsequent pain, trauma, isolation, and stigma. The project proposes a solution to broken or inhibited family communication: the engagement of all family members in healing …

The Effects Of Reward And Risk Level Associated With Speeded Actions: Evidence From Behavior And Electroencephalography, Xingjie Chen

Masters Theses

Choosing a course of action in our daily lives requires an accurate assessment of the associated risks as well as the potential rewards. The present two studies investigated the mechanism of how reward and risk level influence the motor decisions of speeded actions (Chapter 2) and its neural dynamics (Chapter 3) by focusing on the beta band (15-30 Hz) oscillation patterns reflected in the EEG signals. Participants performed a modified version of the Go-NoGo task, in which they earned reward points based on the speed and accuracy of response. On each trial, the reward points at stake (120 vs. 6) …

Influence Of Household Chaos On Associations Between Physiology And Behavior, Sarah Mccormick

Masters Theses

Internalizing behaviors, or behaviors related to behavioral inhibition and the tendency to withdraw from novelty or uncertainty, are stable over time. There is substantial evidence indicating the association between greater resting right lateralized frontal EEG alpha asymmetry and negative affect as well as internalizing behaviors (Coan & Allen, 2003; Henderson, Fox, & Rubin, 2001; Fox, 1991). Further, right frontal asymmetry has been shown to be a stable marker of the presence of psychosocial risk (e.g. child maltreatment; see Peltola, Bakermans-Kranenburg, Alink, Huffmeijer, Biro, & van IJzendoorn, 2014 for meta-analyses). However, little is known about the influences of the home and …

The Effects Of Gateway Width On Driver Yielding To Pedestrians: A Systematic And Parametric Analysis, Jonathan M. Hochmuth

Masters Theses

The gateway in-street sign treatment has been demonstrated to be a cost-effective method for increasing driver yielding behavior at crosswalks. In the present study, wide and narrow gateway widths were compared at two sites to determine if there was a differential effect on driver yielding behavior. Then, the relationship between width and yielding was refined with a parametric analysis at one of these sites. Gateway width was varied in two-foot intervals from 12ft to 18ft. The results indicated an inverse relationship between gateway width and driver yielding behavior. There are likely two variables related to this effect. First, because drivers …

Evaluation Of Generalized And Specific Token Reinforcement Using A Paired Stimulus Preference Assessment And Progressive Ratio Schedules, Haily K. Traxler

Masters Theses

Skinner (1953) stated that the effects of generalized conditioned reinforcers should maintain longer than specific conditioned reinforcers because their effects are not dependent on a particular motivating operation. Tokens easily model different levels of generality because tokens can be paired with one or more back-up reinforcers. In the current study, three types of tokens were assessed that could be exchanged for either salty snacks, food and drinks offered in a small marketplace, or money on a gift card. Token preferences were assessed using a Paired Stimulus preference assessment and a progressive ratio (PR) task. The results of the preference assessment …

Application Of A Three-Lever Drug Discrimination Method To Differentiate The Interoceptive Stimulus Effects Of 3, 4-Methylenedioxypyrovalerone And 4-Methylmethcathinone In Male Sprague-Dawley Rats, Trent Bullock

Masters Theses

Psychoactive “bath salts” represent a continuing drug abuse problem. The synthetic cathinones, 3, 4-methylenedioxypyrovalerone (MDPV) and 4-methylmethcathinone (4-MMC) are popular constituents of “bath salts” in the United States and the United Kingdom, respectively. Addiction to these substances has proven difficult to treat, possibly requiring targeted therapeutics. Drug discrimination is a preclinical assay that may aid in treatment development. Thus far, two-lever (drug vs no drug) discrimination studies have exhibited asymmetrical substitution patterns between 4-MMC and MDPV. Therefore, a three-lever discrimination method was employed in which 12 male Sprague-Dawley rats were trained to discriminate 0.5 mg/kg MDPV, 2.0 mg/kg 4-MMC, and …

Contribution Of Monoaminergic Mechanisms To The Discriminative Stimulus Effects Of 3,4-Methylenedioxypyrovalerone (Mdpv) In Sprague-Dawley Rats, Harmony I. Risca

Masters Theses

3,4-Methylenedioxypyrovalerone (MDPV) is a popular synthetic cathinone reported to have a high abuse potential and comparable pharmacological actions to those of cocaine. The aim of this study was to evaluate a variety of monoaminergic agents for substitution, potentiation, or antagonism in rats trained to discriminate MDPV. Male Sprague-Dawley rats were trained to discriminate 0.5 mg/kg MDPV and a variety of monoaminergic drugs were tested for substitution and/or potentiation of the MDPV cue. In separate experiments, stimulus antagonism tests were conducted with selected dopamine antagonists or serotonin antagonists in rats trained to discriminate 1 mg/kg MDPV. Full substitution for MDPV was …

A Parametric Analysis Of Choice Under Risk, David W. Sottile

Masters Theses

Accurate assessment of risk propensity is important because risky choices underlie a broad range of behavioral problems. The Balloon Analogue Risk Task (BART) is an assessment that measures propensity to engage in risky choice. While this is a useful assessment, the BART changes two variables that affect risky choice simultaneously, probability of an undesirable outcome and stake size, which cannot be separated within the context of the BART. The goal of this study was to evaluate the separate and combined effects of key factors that are likely to risky choice (Magnitude of payoff, probability of an undesirable outcome, and stake …

Children's Self-Regulation During Reward Delay, Abigail Fontaine

Masters Theses

Individuals who display high levels of reward sensitivity are motivated by and respond to reward related cues, thus exhibiting more approach-motivated behaviors. A majority of the research on physiological indices of reward sensitivity in relation to self-regulatory abilities has focused on adults or adolescents, with relatively little work examining these associations in children. Thus, the current study sought to examine whether a common neural measure of reward sensitivity, left frontal electroencephalogram (EEG) asymmetry, assessed in early childhood was predictive of children’s later self-regulation abilities in the context of reward delay. Emerging inhibitory control skills were also examined as a potential …

Effort-Related Motivational Dysfunctions: Behavioral And Neurochemical Studies Of The Wistar-Kyoto Rat Model Of Depression, Brendan Abbott

Masters Theses

Depression and related disorders are characterized by motivational dysfunctions, including deficits in behavioral activation and exertion of effort. Animal models of relevance to depression represent a critical starting point in elucidating the neurobiological mechanisms underlying motivational dysfunctions. The present study explored the use of the Wistar-Kyoto (WKY) animal model of depression to examine effort-related functions as measured by voluntary wheel running and performance on a mixed fixed ratio 5/progressive ratio (FR5/PR) operant task. Given the known link between activational aspects of motivation and the mesocorticolimbic dopamine (DA) system, the behavioral effects of d-amphetamine (0.5 and 1.0 mg/kg, IP), a psychostimulant …

Peer Attention Modeling With Head Pose Trajectory Tracking Using Temporal Thermal Maps, Corey Michael Johnson

Masters Theses

Human head pose trajectories can represent a wealth of implicit information such as areas of attention, body language, potential future actions, and more. This signal is of high value for use in Human-Robot teams due to the implicit information encoded within it. Although team-based tasks require both explicit and implicit communication among peers, large team sizes, noisy environments, distance, and mission urgency can inhibit the frequency and quality of explicit communication. The goal for this thesis is to improve the capabilities of Human-Robot teams by making use of implicit communication. In support of this goal, the following hypotheses are investigated: …

Age Group Differences In Affect Responses To A Stressor, Molly Mather

Masters Theses

Older adults may be better able to modulate their emotional experiences than younger adults, and thus may recover more quickly from negative stressors. Additionally, older adults may be more likely to experience co-occurrence of negative and positive emotions in the setting of negative stressors, which may facilitate emotion recovery. To date, few studies have investigated the nature of age group differences in spontaneous emotional responses to a standardized stressor. The current study utilizes a laboratory mood manipulation to determine age group differences in emotion recovery in negative and positive affects, as well as age group differences in the co-occurrence of …

Borderline Personality And Risk-Taking: Examining The Role Of Impulsivity Across Domains, Colten Karnedy

Masters Theses

Individuals with borderline personality disorder (BPD) and high levels of BPD traits have demonstrated greater rates of engagement in risky, self-destructive behaviors compared to healthy controls. Specifically, impulsivity has been theorized to underlie many of these risky behaviors. Although existing self-report literature suggests that individuals with BPD are more impulsive than controls, evidence from behavioral measures remains inconclusive. Likewise, there is scant research examining specific domains of impulsivity associated with risky behaviors in BPD, which is problematic given that impulsivity is a diagnostic criterion for BPD. Thus, the proposed research aims to bridge this gap in the literature by examining …

Understanding Relational Competence In Emerging Adult Adoptees: A New Way To Conceptualize Competence In Close Relationships, Krystal K. Cashen

Masters Theses

Relatively little research has focused on the positive adjustment of emerging adult adoptees (Palacios & Brodzinsky, 2010). Given the developmental context of emerging adulthood (Arnett, 2000), it is important to select a measure of adjustment that reflects the increased ambiguity seen in this time period. The present study aims to develop and validate a measure of relational competence, or competence in one’s closest relationship regardless of relationship type (i.e., romantic vs. nonromantic). This measure will be created by adapting the Romantic Competence Interview, a measure of romantic competence previously used with emerging adults (Shulman, Davila, & Shachar-Shapira, 2011). Participants …

A Photo Illicit Study Of Black Women's Sense Of Belonging At A Predominately White Institution, Kayla Alexandria Slusher

Masters Theses

This qualitative study sought to examine how Black women define and create their sense of belonging while attending a predominately White institution using a photovoice approach. The women took photographs of spaces that they frequently occupy and then engaged in a face-to-face interview to discuss the photographs. The researcher also investigated four Black women, ranging from junior to graduate level, to identify how they developed a sense of belonging at the research site institution. Results of the study showed that a feeling of comfort was most important when identifying belongingness in a space. The participants were able to create a …

The Development Of Serial Killers: A Grounded Theory Study, Meher Sharma

Masters Theses

The worldview that portrays a serial killer as being a white male, an evil monster with unusual appearance, having dysfunctional relationships (Yaksic, 2015), engaging in animal torture or being sexually or physical abused in childhood, and therefore, sadistically killing for sexual gratification should be challenged (Beasley, 2004). Leyton (1996) and Skrapec (2001) suggested researchers should approach with open minds while searching for knowledge relating to this phenomenon without preconceived assumptions or hypotheses. Furthermore, every serial killers' drive to kill multiple victims may be unique, dependent on his/her history and experiences, and is therefore difficult to quantify (Yaksic, 2015). The current …

An Analysis Of Extended Strings Of Hits And Misses In A Mental Telepathy Task, Gregory R. Peck

Masters Theses

The current study was designed to reanalyze archival data from the Eastern Illinois University parapsychology lab to determine the frequency of strings of hits and misses. Four datasets were included in the analyses, comprising a total of 348 participants. It was hypothesized that there would be more strings of hits and/or misses than expected by chance; there would be a difference between the number of strings of hits and the number of strings of misses; and participant scores on a 7-point belief in psi scale would be related to the frequency of hits and misses. Results indicated that no significant …

Linguistic Correlates Of The Quiet Ego In Narratives About The Self, Katherine Maurer

Masters Theses

Increasingly, research has shown that the drive to elevate the self and the excessive pursuit of self-esteem have negative effects on well-being and mental health. In addition, many of the defensive and aggressive tendencies seen in psychological research can be seen as efforts to defend and elevate the self. In contrast to these tendencies, the quiet ego construct describes a state of ego balance characterized by an inclusive sense of identity, perspective-taking, detached awareness (mindfulness), and growth orientation. The quiet ego and related qualities have been associated with many positive outcomes. A body of research using the Linguistic Inquiry and …

Binge Eating Disorder: Relationship To Physical And Emotional Factors, Taylor M. Mcmillan

Masters Theses

Binge eating disorder (BED) is a new core diagnosis within the Diagnostic Statistical Manual Fifth Edition (DSM-5; APA, 2013). Because binge eating disorder is a new diagnosis, research within this area is both lacking and developing quickly. Social physique anxiety and emotion regulation have been linked previously to binge eating disorder. In contrast, there is little research on the potential link between physical activity and binge eating disorder; however, physical activity has been shown to have potential treatment benefits for binge eating. This study examined BED on a continuum and its links to physical activity, emotion regulation, and subtypes of …

Students Perspective Of Healthy Living In College, Andrea Coxey

Masters Theses

Using qualitative methodology, the researcher studied what participants definition of a healthy lifestyle as compared to how they actually live. Through conducting six one on one interviews with participants, it was found that physical health was the most widely recognized aspect of health, and that each participant had a unique definition of health. Mental health was not initially recognized by participants but was shown to be an important connection to all aspects of health including physical health, emotional health, sleep and nutrition. Participants recognized the importance of involvement and their transition to college as impacting their definition of health and …

The Role Of Contact And Empathy In Stigma Toward Individuals With Mental Illness Among Mental Health And Non-Mental Health Professionals, Quincy A. Knolhoff

Masters Theses

This study was designed to help identify the factors that predict people's stigmatized attitudes toward individuals with mental illness. Corrigan (2002) suggested that stigmatized beliefs about individuals with mental illness may be detrimental to the potential recovery of these individuals, their self-esteem, empowerment, and their integration into society. One factor that has been found to reduce this stigma is personal contact with mentally ill individuals (Corrigan et al., 2002). Additionally, research has shown that empathy and principled moral reasoning are negatively correlated with prejudice, or stigma (McFarland, 2010). The current study examined level of contact, employment in a mental health …

Social Anxiety And Drinking Behaviors In College Students: Mediated By Alcohol Outcome Expectancies Specific To Social Situations?, Toby Board

Masters Theses

Understanding the relationship between social anxiety and problematic drinking is a difficult task. Studies examining this relationship have commonly found a positive correlation between social anxiety and drinking behaviors, although the literature is marked by mixed results. If social anxiety does positively predict alcohol use, then what accounts for this relationship? Some researchers posit that alcohol outcome expectancies may be a mediator for this relationship. Alcohol outcome expectancies specific to the context of social evaluative situations may be a stronger mediator than general alcohol outcome expectancies. A study to test this mediation was conducted with xxx undergraduate students. Results showed …

Relational Aggression In College Students, Nicole Parker

Masters Theses

Researchers have long theorized that females may be as equally aggressive as males, but the form of aggression most frequently manifested by females may be nonphysical. This thinking lead to the examination of relational aggression, which is a type of aggression intended to harm others' peer relationships. Numerous studies over the last 20 years have examined relational aggression in children and the maladaptive behaviors associated with such aggression. However, far less is known about relational aggression in older students or young adults. Thus, this paper reviews the present literature on relational aggression in college students, focusing on three potential predictors …

Factors Influencing Teacher And Adminstrators' Knowledge And Attitudes About Adolescent Depression, Suicide, And Prevention, Kayla N. Quick

Masters Theses

To date, research has yet to be conducted that examines U.S. secondary school teachers' and administrators' attitudes toward intervening with potentially depressed and/or suicidal students. Additionally, research is needed to identify the demographic characteristics of educators that are associated with general knowledge of adolescent suicide and the risk factors and warning signs that often accompany it. The purpose of the present study was to examine the following hypotheses: 1) certain characteristics (e.g. gender, years of experience with educating children, the amount of training received on adolescent depression/suicide, and knowledge of adolescent suicide and depression) are better predictors of attitudes toward …

Factors Influencing Persistence Of Students With Learning Disabilities At Four-Year Institutions, Abigail Frye

Masters Theses

This study investigated the persistence and transition of college students with learning disabilities at a mid-sized Midwestern university. The qualitative, narrative approach was used to determine which factors influenced the persistence of students with learning disabilities at a four-year, mid-sized university and which college services and resources students with learning disabilities utilized. This research found that students do utilize college services and supports to assist through their transitions into college. The participants in this research relied on the support of their family and friends while they approached and navigated their college transition. This study found that students with learning disabilities …

Predictors Of Bulimia Nervosa Symptoms, Paulina A. Zdanowicz

Masters Theses

Bulimia nervosa (BN) symptoms involve binge eating, compensatory behaviors, and preoccupation with food and body image. A wealth of research has linked factors such as impulsivity and obsessive-compulsive behaviors to BN. In contrast, social appearance anxiety has not been frequently studied, as it is a new concept, especially as it relates to BN symptoms. This study will examine the links of BN symptoms to social appearance anxiety, impulsivity, and obsessive-compulsive behaviors. Specifically, it was predicted that social appearance anxiety, impulsivity, and obsessive-compulsive behaviors will positively predict symptoms of BN. The main model in this study found that social appearance anxiety …

Is The Relationship Between College Drinking Behaviors And Social Anxiety Mediated By Alcohol Expectancies And Traumatic Life Experiences?, Cortney Lin Kingsmill

Masters Theses

The relationship between alcohol consumption and social anxiety is difficult to understand, as there have been mixed findings in the research. In general, a positive correlation has been found between the two, with a focus on the mediating effect of alcohol outcome expectancies. Both positive expectancies and trauma have been correlated positively with social anxiety and drinking behavior. This paper reviews the literature and examines the relationship between social anxiety and alcohol consumption. A mediated model between these two variables with the mediators being alcohol expectancies and traumatic experiences was proposed, but this model did not fit the date. Specifically, …

The Effects Of Music Therapy Techniques On Clients In A Substance Abuse Group, Moyosore Fabiyi

Masters Theses

The purpose of this study was to examine the effects of music therapy on clients with substance abuse history attending group sessions in a behavioral health facility. Specifically, the mechanism by which lyric analysis or the musical component may lead to positive therapeutic outcomes was examined. In order to assess the effectiveness of music therapy techniques, a comparison was made between conditions of music alone, lyric analysis alone and music with lyric analysis. One may be able to argue that the mechanism by which music therapy affects clients may lay within the music itself and clients listening to that music. …
