Toughness Predicts Performance In College Football, Joseph B. Rigoni

Department of Psychology: Dissertations, Theses, and Student Research

A premium college football player is estimated to generate over $1 million for his program, so optimal player assessment and selection are paramount. Lean body mass, back squat, and vertical jump have been the most predictive physical test scores, but such metrics typically account for less than 10% of variance in football performance. NFL scouts have tended to rely on vertical jump, 40-yard dash, and 20-yard shuttle scores, but interestingly, reliance on none of the physical tests conducted at the NFL Combine was predictive of team success; in fact, teams that relied on fewer total physical test scores tended to …

Social Affiliation: A Model Of Anxious Avoidance In Women, Milena Stoyanova

Department of Psychology: Dissertations, Theses, and Student Research

There is substantial evidence demonstrating that women experience greater anxiety and fear compared to men. However, our understanding of specific factors accounting for women’s greater vulnerability remains rather limited. Taylor and colleagues (2000) proposed that women may have a different biobehavioral response to stress, which has evolved to protect and nurture offspring. The tend-and-befriend model provides new opportunities to explore underlying processes that may contribute to women’s greater anxiety and fear.

The present study examined women’s stress response combined with the absence of positive social contact as it relates to the presentation of fear and anxiety. One hundred and seven …

Times Are A Changin': Gender Role Orientation And Alcohol Use, Jessica Lauren Fugitt

Graduate Theses and Dissertations

Alcohol misuse is an important public health concern as it is related to an elevated probability of experiencing a number of negative life events. Historically, alcohol consumption patterns seemed to differ according to sex, but more recent research suggests that the difference has narrowed as gender role orientations have converged. Further, it seems that gender role orientation more reliably predicts differences in patterns of use than biological sex. The goal of this two-part study was to investigate the relation of gender role orientation and alcohol use behaviors with the expectation that masculine gender role orientation would be associated with these …

To Conform Or Not To Conform: An Examination Of The Effects Of Mock Jury Deliberation On Individual Jurors, Ashley S. Bowser

Electronic Theses and Dissertations

The jury method is a unique social setting in the Criminal Justice system that provides opportunity for social influence to occur. Questions about the formation of jurors’ individual and collective decisions have stimulated a great deal of interest and research. This study is a review of the juror decision-making process and the various sources of influence that can affect it. Mock jurors were asked to review a mock criminal trial as well as the testimony of 2 witnesses. Upon reviewing the case, a predeliberation verdict (guilty or not guilty) and the degree of certainty of that decision was made. Once …

Fruit And Vegetable Consumption At Bear River Charter School; A Demand Curve Analysis, Mckelle Tobey

Undergraduate Honors Capstone Projects

Many variables contribute to the rising prevalence of children being overweight and obese, one being poor nutrition and the lack of a balanced diet. Proper nutrition helps children to grow and develop normally, as well as lowers the risk of developing chronic problems such as cardiovascular disease, coronary heart disease, and certain cancers later in life. Conducted alongside an applied behavioral intervention to increase consumption of fruits and vegetables, a behavioral economic evaluation of demand curves was administered to students in the fifth through eighth grades. Findings suggest that the intervention had no significant effect on the elasticity of the …

Are They All The Same? An Exploratory, Categorical Analysis Of Drinking Game Types, Joseph W. Labrie, Phillip J. Ehret, Justin F. Hummer

Heads Up!

Drinking games have become a ubiquitous part of the college student drinking culture and are associated with drinking to intoxication and increased alcohol consequences. Contemporary research commonly considers drinking games holistically, with little to no consideration to the different drinking game types. The current study describes the creation of a novel DG categorization scheme and reports differences between DG categories. Participants were 3421 college students (58% female) who completed online surveys. Based on participant responses, 100 distinct drinking games were identified and defined. Two student focus groups were conducted in which drinking game definitions and rules were verified by students. …

Anxiety Symptoms In Individuals With High Functioning Autism, Jane C. Kelleher

Honors Scholar Theses

Research indicates a complicated relationship between anxiety disorders and autism spectrum disorders (ASDs). The current study examined the relationship between anxiety symptoms and ASD in 30 Optimal Outcome (OO) individuals, 33 High Functioning Autism (HFA) individuals, and 34 Typically Developing (TD) individuals. The groups were compared on the K-SADS measure of anxiety symptoms. The HFA group presented greater anxiety than both the OO and TD groups, and the OO and TD groups only differed on one anxiety symptom. Across all three groups, there was a significant association between greater anxiety symptoms and a higher level of social and communicative impairment. …

Participatory Approaches To Purchasing Decisions Within The Healthcare System, Alana Dorris

Honors Scholar Theses

The main purpose of this study was to use sociotechnical and Macroergonomic principles to better understand purchasing policies and procedures at a large hospital. The study hypothesized (H1), that most purchasing is done through GPOs rather than manufacturers directly, and that GPOs are cost effective but impede innovation. It also hypothesized (H2), that this hospital, representative of the current healthcare purchasing process at most hospitals, has limitations to the amount of end-user participation in the purchasing decision process.

Olfactory Working Memory: The Role Of Perceived Odor Name-Ability, Spencer Lawrence Macadams

Masters Theses and Doctoral Dissertations

The purpose of this study was to examine the relationship among three factors: perceived odorant name ability, whether the odorant was ingested through a single nostril or both nostrils, and how the odorant is represented in working memory. Participants smelled odorants through the left or right nostril or with both nostrils and then provided an identifying label for each odor and rated how accurately their label represented the odor. After a short delay, the participants were given a new stimulus set consisting of new and old odorants. Participants were asked to provide a label for the odor and determine whether …

Understanding Organizational Wellness: The Impact Of Perceived Organizational Support, Motivation, And Barriers On The Effectiveness Of Wellness Programs, Aaron Owsley Manier

Masters Theses and Doctoral Dissertations

Organizational wellness programs can serve as a powerful tool for organizations to improve the health and well-being of employees. As organizational wellness grows in popularity and implementation, organizations should seek to understand employee perceptions of these programs to maximize their effectiveness and use. The present study examined the effect of perceived organizational support of wellness, core self-evaluation, and motivation/interest for wellness programs on wellness program use and satisfaction. This effect was tested with barriers to use and participative wellness design as possible mediators. Motivation and interest had a strong and direct effect on program use and satisfaction, while both organizational …

Can't We All Just Get Along? The Impact Of Goal Orientation On The Coach-Athlete Relationship And Coach-Athlete Communication, Meredith J. Nordbrock

Masters Theses and Doctoral Dissertations

Research has demonstrated that the coach-athlete relationship is one of the key interpersonal factors that influences outcomes such as performance (Sánchez, Borrás, Leite, Battaglia, & Lorenzo, 2009), satisfaction with performance (Jowett & Don Carolis, 2003), and dropout rates (Fraser-Thomas, Côté, & Deakin, 2008). However, relatively little is known about the factors necessary to achieve and/or maintain a high-quality coach-athlete relationship. Building upon Jowett and Poczwardowski’s (2007) integrated research model, this study of 355 coach-athlete dyads explored how congruence (i.e., similarity, fit) of goal orientation (GO) impacted the quality of the coach-athlete relationship and coach-athlete communication. Specifically, it was hypothesized that …

Sequential Lineups Reduce Unconscious Transference And Mistaken Lineup Identification: But At What Cost?, Paul Rosenberg

Masters Theses and Doctoral Dissertations

Adult participants were shown one of two versions of a video portraying a theft. In the transference condition the video contained a scene with the bystander. The control condition did not have the bystander, but another person in his place. In Experiment 1 participants in both conditions were shown a sequential bystander present culprit absent lineup. Transference participants were significantly more likely to misidentify the bystander as the thief than control participants, an effect that was small in magnitude when compared to previous studies. Experiment 2 used the same materials and procedures, except the bystander was replaced in the lineup …

Challenge And Hinderance Stressor Appraisals, Personal Resources, And Work Engagement Among K-12 Teachers, Isaac Benjamin Thompson

Masters Theses and Doctoral Dissertations

Stress has long been conceptualized as consisting of two factors, eustress, or good stress, and distress, or bad stress (Selye, 1956). The occupational stress literature identifies challenge stressors as those associated with favorable outcomes, and hindrance stressors as those associated with negative outcomes (Cavanaugh, Boswell, Roehling, & Boudreau, 2000). The current study had three objectives: 1) to investigate occupational level stressor appraisal by K-12 teachers, 2) to explore how the perception of the availability of resources influences individual level stressor appraisal, and 3) to test differential outcomes of challenge and hindrance stress. Results indicate that K-12 teachers appraise workload as …

Perceptions Of Confessions By Juvenile Suspects: Effects Of Interrogation Technique And Suspect Age, Kelsey Ana Villamarin

Masters Theses and Doctoral Dissertations

Juvenile suspects are far more prone than adults to make false confessions. Two interrogation techniques known as Minimization (gentle, friendly approach used to gain suspect’s trust) and Maximization (coercive approach using harsh questioning and scare tactics) have been used frequently in cases of proven false confessions in juveniles. The present research examined perceptions of a juvenile suspect’s confession in four hundred sixty four participants recruited from psychology courses. They read a sexual assault vignette involving a 12- or 16- year-old male suspect and police interview excerpts utilizing either Minimization or Maximization interrogation techniques. Participants’ views depended on their gender, the …

Relationships Among Nursing Burnout, The Big Five Personality Factors, And Overall Self-Concept: The Impact Of Assessing Common Method Variance, Matthew Thomas Ecie

Masters Theses and Doctoral Dissertations

The purpose of the present study was to evaluate the extent to which common method variance (CMV) impacted many of the relationships between personality traits and the construct of burnout among registered nurses. It was hypothesized that once CMV was calculated and controlled for, relationships between personality traits and burnout would be weakened. Data were collected from working registered nurses (N = 274) and from BSN student nurses (N = 8). Scales measuring the IPIP Big Five, burnout, hardiness, core self-evaluation, optimism, and stress in general were combined to create a survey questionnaire. Results indicated burnout among nurses was significantly …

Accessing Learning In The Adult Zebrafish With A Novel Associative Learning Task, David Joseph Jouandot Ii

Dissertations

The zebrafish (Danio rerio) is accepted in the developmental and genomic communities as a model organism. However, the capacity for the zebrafish as a behavioral model has yet to be fully acknowledged. The research presented provides evidence validating the novel task, aids in gaining a better understanding of the learning processes, and identifies individual differences. The novel associative learning task differs from any present well established behavioral model and lends itself to future development. The task provides the zebrafish community with a high output behavioral task which is readily replicated and allows one researcher to test between eight …

Tactile Behavior In A Group Of Captive Rough-Toothed Dolphins As A Function Of Opportunities To Play With Objects, Kelly Ann Caffery

Dissertations

Cetaceans live in complex physical and social environments that are frequently changing. In contrast, the captive environment for marine mammals is often lacking in stimulation. As a result, enrichment is often used to increase species-typical behaviors and enhance the well-being of the animals. The purpose of this study was to compare the effects of enrichment objects on the social behavior of a group of seven captive rough-toothed dolphins (Steno bredanensis). Observations of this species in the wild suggest it may have a particular affinity for tactile and object play behaviors. Therefore, these behavior categories were a primary focus …

Effects Of Food Dispersion On Dominance Related Behaviors In Garnett's Bushbaby (Otolemur Garnettii)?, Kyle Daniel Edens

Dissertations

Socio-ecological theorists tie primate social structure diversity to variations in habitats within which primate species reside. This premise permits laboratory researchers to investigate specific factors that influence or relate to social structure formation and maintenance. The focus of the current investigation was three fold. We first aimed to determine the relationships between traditional and non-traditional behavioral measures of dominance, then evidence for dominance hierarchy formation was examined, and various hypotheses were tested to discern if adjustments in the foraging context altered social behaviors in Garnett’s bushbaby (Otolemur garnettii). It was determined that animals likely to displace conspecifics were …

How Psychology’S Empirical Results Can Benefit The Criminal Justice System: Expert Testimony, Ford C. Mccurry

Electronic Theses and Dissertations

Brigham and Bothwell (1983) claimed that jurors have a scientifically incorrect view of eyewitness testimony. The purpose of this study was to examine the most beneficial way to assist the jury in dealing with eyewitness testimony. Duckworth, Kreiner, Stark-Wroblewski, and Marsh (2011) applied interactive participation in an eyewitness activity and expert testimony to a mock-jury dealing with eyewitness testimony and found that those who participated in the activity had significantly fewer convictions. The methodological framework of the Duckworth et al. study was applied to East Tennessee State University criminal justice undergraduates. Although this study did not find any significant effects …

Witnessing Reconciliation Reduces Arousal Of Bystanders In A Baboon Group (Papio Hamadryas Hamadryas), Peter G. Judge, Katherine A. Bachmann

Faculty Journal Articles

Reconciliation is the occurrence of friendly behaviour between opponents shortly after an aggressive conflict. In primate groups, reconciliation reduces aggression and post-conflict arousal. Aggression within a group can also increase arousal of bystanders (e.g. increase bystanders’ rates of self-directed behaviour). Since reconciliation reduces aggression between opponents, we tested whether it also reduces self-directed behaviour in bystanders. Following aggression in a captive group of hamadryas baboons, one observer conducted a focal sample on one of the combatants to document reconciliation and a second observer simultaneously conducted a focal sample on a randomly selected bystander. Matched control observations were then collected on …

Predictors Of Resilience And Their Influence On Adaptation After Elective Abortion, Anna Marie Antonio

UNLV Theses, Dissertations, Professional Papers, and Capstones

The literature has inconsistent findings on the impact of an induced abortion on a woman's physical and psychological well-being. The purposes of this survey research design using correlation and multiple regression analyses were to determine the relationship between protective factors, risk factors, resilience, and outcomes (positive or negative). Additionally, this study investigated whether resilience, protective factors, and risk factors could be predictive of positive or negative outcomes following induced abortion. A convenience sample of 216 women was recruited nationally from hospitals, clinics, and various organizations. Inclusion criteria included women, 18 years of age or older, living in the United States, …

Class Is Out: Mental Health Professionals' Social Class Identification And Classist Attitudes Toward Low-Income Clients, Kipp Ryan Pietrantonio

Theses and Dissertations

Social class as a variable of culturally competent psychology remains a misunderstood and understudied phenomenon. This study was designed to explore how mental health providers’ social class of origin and classist attitudes impact their beliefs and treatment of clients from different economic backgrounds. This was accomplished by exploring five domains across two vignettes that varied in SES indicators (Low-­‐Income vs. Middle Class Vignette). The domains of study included classist beliefs, GAF scores with or without treatment over time, positive and negative stereotype endorsement, perceptions of the therapeutic relationship, and potential treatment modalities. Clinicians did not rate the vignettes differently in …

Lazy Thinking: How Cognitive Easing Affects The Decision Making Process Of Business Professionals, Gianmarco Armenia

Honors College Theses

This paper examines how business and financial decision making are influenced by behavioral biases such as cognitive ease, overconfidence, herding and the endowment effect. I do this in two ways. First, I show historical examples of irrational decisions and the detrimental effects on the individual, society, the company, and shareholders from these decisions. Second, I conduct a survey of business students to examine how susceptible they are to behavioral biases. I find that most students are in fact allowing cognitive easing to alter their decisions negatively.

Early Life Stress, Drug Abuse, Exercise Effects On Bdnf And Sex-Influenced Excercise Differences, Karissa Dold

Honors College Theses

In 2011, the U.S. reported 3 million child maltreatment cases, an uncomfortably high but recurring figure each year. Research shows exposure to early life stress (ELS) increases an individual’s susceptibility to substance abuse, specifically of nicotine, alcohol, and cocaine. Increased susceptibility may result from dysregulation of the HPA axis sustaining activation into adulthood after ELS. Hyperactivation of the HPA axis significantly reduces hippocampal BDNF, a neurotrophin involved in neuronal growth and plasticity. Reduced hippocampal BDNF may be a factor in substance abuse vulnerability. Additionally, research shows exercise protects hippocampal BDNF from stress induced down-regulation. To explore these relationships, this study …

Can Preservice Teachers Be Taught To Become Reflective Thinkers During Their First Internship Experience?, Stephanie Weber

Doctoral Dissertations and Projects

Reflective thinking is a developmental process that progresses over time from a technical, routine level to a critical, self-evaluating level. Preservice teachers, who tend to stay in the technical, routine level of critical thinking without guidance, need to be taught how to become reflective thinkers so that they are able to identify and analyze their own personal teaching practices, connect theory with practice, and understand why they are teaching. By learning to be more critically reflective in their thinking, preservice teachers will become more effective teachers, thus having a positive impact on student achievement. This dissertation research study quantitatively evaluated …

A Grounded Theory Study Investigating How Parents' Adolescent Experiences Influence Their Attitudes And Behaviors Toward Their Children's Middle School Education, Brenda Williams

Doctoral Dissertations and Projects

The purpose of this qualitative grounded theory study was to explore ways in which parents' past school experiences as adolescents influence their attitudes and behaviors toward their children's education. Three research questions related to parents' past experiences, current attitudes, and participation guided the study. Hope County School system (pseudonym), a suburban school system in the southeastern United States, was the setting for the study. Participants included 12 middle school parents. Three instruments were used for data collection: interviews, surveys, and reflective booklets. Data analysis was conducted using the grounded theory process of open coding, axial coding, and selective coding. From …

Doctoral Dissertations and Projects

The purpose of this phenomenological qualitative research study was to explore how young adults who have an autism spectrum disorder perceive their life choices after secondary education. The focus participants in the sample were young adults with Autism Spectrum Disorder (ASD). For the purpose of this research, ASD includes autism and Asperger's Disorder. Participants between the ages of 18 and 33 were located through purposive sampling in the states of Minnesota and Tennessee, as the author has previously worked in these states. Participants were asked five open ended focus questions during the span of two face to face interviews. Questions …

A Theory-Driven, Longitudinal Evaluation Of The Impact Of Team Training On Safety Culture In 24 Hospitals, Katherine J. Jones, Anne M. Skinner, Robin High, Roni Reiter-Palmon

Psychology Faculty Publications

Effective teamwork facilitates collective learning, which is integral to safety culture. There are no rigorous evaluations of the impact of team training on the four components of safety culture—reporting, just, flexible and learning cultures. We evaluated the impact of a year-long team training programme on safety culture in 24 hospitals using two theoretical frameworks.
