Priming Of Grasping Muscles When Viewing A Safety Handle Is Diminished With Age, David A.E. Bolton, Sarah E. Schwartz, Manhoud Mansour, Garrett Rydalch, Douglas W. Mcdannald

Kinesiology and Health Science Faculty Publications

Merely viewing objects within reachable space can activate motor cortical networks and potentiate movement. This holds potential value for smooth interaction with objects in our surroundings, and could offer an advantage for quickly generating targeted hand movements (e.g. grasping a support rail to maintain stability). The present study investigated if viewing a wall-mounted safety handle resulted in automatic activation of motor cortical networks, and if this effect changes with age. Twenty-five young adults (18–30 years) and seventeen older adults (65+ years) were included in this study. Single-pulse, transcranial magnetic stimulation was applied over the motor cortical hand representation of young …

Exploring The Link Between Genetics, Chronic Stress, And Depression, Michael Woller

Undergraduate Research and Creative Opportunities (URCO) Grant Program

Depression is a very debilitating mental illness that affects about 7% of the American Population [1] and up to about 350 million people worldwide [2]. Since the cause for depression and the reason why some individuals are more vulnerable than others are currently unclear, studying paradigms that model depression in animals, such as the learned helplessness paradigm, is useful to explore possible mechanisms and devise new treatments. To explore a possible link between genetics, chronic stress and depression, we have exposed mice vulnerable to stress to an inescapable forced swim paradigm. During the forced swim test, the mice were monitored …

Effect Of Acceptance Versus Psychoeducation On Hoarding, Clarissa W. Ong

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Hoarding disorder (HD) is a mental health condition characterized by difficulty letting go of possessions, resulting in clutter that prevents use of active living spaces. Consequences associated with hoarding include strained family relationships, distress for children in the home, and increased burden on social services. Currently, the most empirically supported treatment for HD is cognitive-behavioral therapy (CBT), which includes such components as education about the nature of hoarding, challenging unhelpful thoughts, and exposure to distressing stimuli. Despite its demonstrated effectiveness, CBT does not result in clinically significant improvement for at least 50% of individuals, indicating the need for alternative interventions …

The Relationship Of Gender-Based Microaggressions And Internalized Sexism On Mental Health Outcomes: A Mother-Daughter Study, Nicole D. Feigt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Subtle occurrences of discrimination, insults, and slights against gender can impact woman of all ages, although little research has been done on the mental health impacts of these events on adolescents or middle-aged women. Additionally, a person’s own views on sex roles and sexism may impact how these events affect them. The following study examined the relationship between mothers and daughters on variables related to ambivalent sexism, gender-based microaggressions, and anxiety and depression. One hundred two mothers and their adolescent daughters completed various online surveys through the use of a Qualtrics panel. The sample was fairly representative, with respondents varying …

Using Ecological Momentary Assessment To Clarify The Function Of Hoarding, Jennifer Krafft

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Experts have argued that hoarding disorder occurs in part because hoarding behaviors help individuals avoid distress and feel positive emotions in the moment. For example, when people who hoard choose to save something rather than discard it, they may avoid feelings of anxiety, and when people who hoard acquire something new, they may feel excited. However, no previous studies have examined whether or not these changes actually occur in the moment. These processes could also potentially be altered by how individuals respond to their emotions in the moment. For example, individuals who hoard may have stronger emotional reactions, distinguish less …

Insomnia And Use Of Sleep Medications In Predicting Risk Of Alzheimer's Disease In The Cache County Study, Elizabeth Kathleen Vernon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Over 71 million Americans will be over the age of 65 by the year 2030. With this rise in adults aged 65 years and older also comes an exponential rise in the estimated number of individuals with Alzheimer’s disease (AD); this number is expected to exceed 24 million Americans by the year 2040. The number one risk factor for AD is older age; this factor is also associated with an increased risk in developing a sleep disturbance. Sleep disturbances have been associated with an increased risk of cancer, heart disease, and decline in overall health. Recent research has examined the …

The Intergenerational Transmission Of Parental Practices That Influence The Educational Outcome Of Latinxs In The United States, Ana E. Kemple Reeves

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parental involvement practices in education have traditionally referred to overt forms of involvement such as attending school meetings, parent teacher conferences, and volunteering at the school. Research suggests that Latinx parents do not utilize these approaches as much as they do subtler practices. These practices are manifested in parents’ communication with their children, their parenting styles, and the academic expectations they place on their children. The current study intended to recognize the parental practices used by Latinx parents that contribute to educational attainment and combat fixed beliefs regarding their lack of involvement in their children’s education. The data collection was …

How Children Describe Negative Adoption Experiences, Mckenzie Paskett

Undergraduate Honors Capstone Projects

Adoption faces stigmas from society which affects peoples' perceptions of adoptees, their birth parents, and adoptive parent s; one of the most prominent being that adoption is the "second best" route to getting children (Baxter, Norwood, Asbury, & Scharp , 2014). Adoption success is mixed with some adapting well, while others have negative experience s. Studying themes about how and why negative adoption experiences happen could be beneficial to preventing them in the future. There is a unique perspective between parents and children and so the central research question for this study is: how do children describe their negative adoption …

Efficient Exploration Of Many Variables And Interactions Using Regularized Regression, Tyson S. Barrett, Ginger Lockhart

Psychology Faculty Publications

The prevention sciences often face several situations that can compromise the statistical power and validity of a study. Among these, research can (1) have data with many variables, sometimes with low sample sizes, (2) have highly correlated predictors, (3) have unclear theory or empirical evidence related to the research questions, and/or (4) have difficulty selecting the proper covariates in observational studies. Modeling in these situations is difficult—and at times impossible—with conventional methods. Fortunately, regularized regression—a machine learning technique—can aid in exploring datasets that are otherwise difficult to analyze, allowing researchers to draw insights from these data. Although many of these …

Cognitive Load Affects Numerical And Temporal Judgments In Distinct Ways, Karina Hamamouche, Maura Keefe, Kerry Jordan, Sara Cordes

Psychology Faculty Publications

Prominent theories suggest that time and number are processed by a single neural locus or a common magnitude system (e.g., Meck and Church, 1983; Walsh, 2003). However, a growing body of literature has identified numerous inconsistencies between temporal and numerical processing, casting doubt on the presence of such a singular system. Findings of distinct temporal and numerical biases in the presence of emotional content (Baker et al., 2013; Young and Cordes, 2013) are particularly relevant to this debate. Specifically, emotional stimuli lead to temporal overestimation, yet identical stimuli result in numerical underestimation. In …

Common Dna Variants Accurately Rank An Individual Of Extreme Height, Corinne E. Sexton, Mark T. W. Ebbert, Ryan H. Miller, Meganne Ferrel, Joann T. Tschanz, Chris D. Corcoran, Alzheimer’S Disease Neuroimaging Initiative, Perry G. Ridge, John S. K. Kauwe

Psychology Faculty Publications

Polygenic scores (or genetic risk scores) quantify the aggregate of small effects from many common genetic loci that have been associated with a trait through genome-wide association. Polygenic scores were first used successfully in schizophrenia and have since been applied to multiple phenotypes including multiple sclerosis, rheumatoid arthritis, and height. Because human height is an easily-measured and complex polygenic trait, polygenic height scores provide exciting insights into the predictability of aggregate common variant effect on the phenotype. Shawn Bradley is an extremely tall former professional basketball player from Brigham Young University and the National Basketball Association (NBA), measuring 2.29 meters …

Using Social Network Analysis To Examine The Intersection Of Adolescent Friendships And Health Behavior, Emily Long

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adolescence marks a vulnerable developmental period for health behavior, and research demonstrates that social context and interpersonal relationships impact the health behavior choices of adolescents. In addition, theories of adolescent development suggest a bidirectional relationship between environmental factors, including social relationships, and health. Friendships are one of the most salient relationships during adolescence, and new methods from the field of social network analysis allow researchers to explicitly examine the mechanisms through which friends influence health behavior, and simultaneously, how health and health behavior impacts the formation of friendships. Importantly, social network methods (e.g., stochastic actor-based models, exponential random graph models) …

Contextual Factors In The Identity Development Of Native American And Latinx Undergraduates In Stem Fields, Angela Marie Enno

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study includes two papers that aimed to provide insights into the experiences of high-achieving Latinx and Native American college students studying science. We wanted to better understand factors that influence these students’ ability to develop a sense of identity that weaves together their hoped-for careers as scientists as well as their cultural identities. We looked at how they feel about working with mentors in science fields who were like them in a variety of ways. We found that many students (especially those with a stronger sense of cultural identity) valued working with mentors who were similar to them in …

Posttraumatic Stress Disorder (Ptsd) And Positive And Negative Social Support As Components Of The Interpersonal Psychological Theory Of Suicide In The United States Military Veterans, Jordan M. Kugler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Veterans are at a greater risk for suicide compared to the general population. Suicide risk further increases for veterans with posttraumatic stress disorder (PTSD). The Interpersonal Psychological Theory of Suicide (IPTS) states that a combination of higher perceived burden and lower thwarted belonging increases risk for suicidal ideation (SI), and when SI is present, higher acquired capability for suicide (ACFS) increases risk for suicide attempt. The IPTS is well supported in samples of the general population, but understudied in military samples. The current study tested the IPTS, using PTSD severity in place of perceived burden, and bothersomeness of negative social …

Survey On Services Provided To Children With Autism Spectrum Disorder In U.S. Public Schools, Kendra Mcpherson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is of utmost importance that students diagnosed with Autism Spectrum Disorder (ASD) in the public school setting across the United States are receiving the best, most researched services and treatments. This study aimed to find out what services and treatments are most commonly being used for students with ASD in the public schools, to see whether or not those practices are supported by research, and to discover how involved parents and families are in the services being provided to their students. This study found that of the top 25 most commonly used practices, 17 of those were supported by …

Gene-Environment Interaction: Brain-Derived Neurotrophic Factor (Bdnf) As A Moderating Factor For The Effects Of Exercise And Diet On Cognitive And Mental Health: The Cache County Study On Memory In Aging, Chelsea L. Sanders

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Cache County Study on Memory in Aging, funded by the National Institute on Aging, studied longitudinal changes in memory and aging over 12 years’ follow-up in a population-based sample of 5,092 older adults in semirural Cache County, UT. Among the extensive interview procedures, researchers collected information regarding the participants’ demographics, health, genetic factors, diet, physical activity, and cognitive abilities. This study has allowed researchers to investigate how genetic and modifiable lifestyle factors interact to predict health, cognitive function, and psychological wellbeing in older adults.

Diet and exercise are important lifestyle factors in maintaining cognitive health and psychological wellbeing throughout …

Personal Growth Following The Challenge Of Becoming A New Parent While Working As A Mental Health Clinician: A Narrative Study, Amie L. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Becoming a new parent can cause both immense joy and immense stress that leads to increases and decreases in a new parent’s feeling of life satisfaction. In addition, working as a mental health clinician is a frequently challenging career. Given that many clinicians also become parents while working during the course of their careers, it is surprising that there is not more research on the experience of clinicians who become new parents. More research is needed to find out how people balance the stresses of new parenthood and their emotionally challenging jobs. There is some research on “stress-related growth” that …

Putting Weight In Context: Acceptance And Commitment Therapy (Act) Guided Self-Help For Weight Self-Stigma, Sarah A. Potts

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Obesity is a serious public health issue within the U.S. and minimal long-term success is found with standard behavioral weight-loss treatments. Typical weight-loss interventions do not acknowledge psychological factors, such as weight-related stigma, which may play a role in the development and maintenance of poor coping behaviors, such as unhealthy eating patterns. Individuals who are obese may often experience weight-related stigma present in society and are ultimately at risk for weight self-stigma, which is related to poor health behaviors and increased psychological distress. Acceptance and commitment therapy (ACT), can be effective for treating numerous mental health presentations, might also be …

The Culture Of Sexuality: Identification, Conceptualization, And Acculturation Processes Within Sexual Minority And Heterosexual Cultures, Joshua Glenn Parmenter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study aimed to provide insights into the experiences of lesbian, gay, bisexual, transgender, or queer/questioning (LGBTQ+) people within LGBTQ+ culture, and to explore how they disclose or conceal their sexual identities within different social environments. A qualitative study enabled me to become immersed within the stories of LGBTQ+ people, in order to better understand the construct and importance of LGBTQ+ culture. Through in-depth interviews and focus groups, 14 members of the LGBTQ+ community from around the nation volunteered to share their experiences with LGBTQ+ culture and their negotiation of identity within heterosexual culture.

From participants’ stories, key themes were …

What Contribution Did Economic Evidence Make To The Adoption Of Universal Newborn Hearing Screening Policies In The United States?, Scott D. Grosse, Craig A. Mason, Marcus Gaffney, Vickie Thomson, Karl R. White

Psychology Faculty Publications

Universal newborn hearing screening (UNHS), when accompanied by timely access to intervention services, can improve language outcomes for children born deaf or hard of hearing (D/HH) and result in economic benefits to society. Early Hearing Detection and Intervention (EHDI) programs promote UNHS and using information systems support access to follow-up diagnostic and early intervention services so that infants can be screened no later than 1 month of age, with those who do not pass their screen receiving diagnostic evaluation no later than 3 months of age, and those with diagnosed hearing loss receiving intervention services no later than 6 months …

Inactivation Of The Medial-Prefrontal Cortex Impairs Interval Timing Precision, But Not Timing Accuracy Or Scalar Timing In A Peak-Interval Procedure In Rats, Catalin V. Buhusi, Marcelo B. Reyes, Cody-Aaron Gathers, Sorinel A. Oprisan, Mona Buhusi

Psychology Faculty Publications

Motor sequence learning, planning and execution of goal-directed behaviors, and decision making rely on accurate time estimation and production of durations in the seconds-to-minutes range. The pathways involved in planning and execution of goal-directed behaviors include cortico-striato-thalamo-cortical circuitry modulated by dopaminergic inputs. A critical feature of interval timing is its scalar property, by which the precision of timing is proportional to the timed duration. We examined the role of medial prefrontal cortex (mPFC) in timing by evaluating the effect of its reversible inactivation on timing accuracy, timing precision and scalar timing. Rats were trained to time two durations in a …

Adding Acceptance And Commitment Therapy To Exposure And Response Prevention For Obsessive-Compulsive Disorder: A Randomized Controlled Trial, Michael P. Twohig, Jonathan S. Abramowitz, Brooke M. Smith, Laura E. Fabricant, Ryan J. Jacoby, Kate L. Morrison, Ellen J. Bluett, Lillian Reuman, Shannon M. Blakey, Thomas Ledermann

Psychology Faculty Publications

The objective of this study was to test whether treatment acceptability, exposure engagement, and completion rates could be increased by integrating acceptance and commitment therapy (ACT) with traditional exposure and response prevention (ERP). 58 adults (68% female) diagnosed with obsessive-compulsive disorder (OCD; M age = 27, 80% white) engaged in a multisite randomized controlled trial of 16 individual twice-weekly sessions of either ERP or ACT + ERP. Assessors unaware of treatment condition administered assessments of OCD, depression, psychological flexibility, and obsessional beliefs at pretreatment, posttreatment, and six-month follow-up. Treatment acceptability, credibility/expectancy, and exposure engagement were also assessed. Exposure engagement was …

The Influence Of A Personal Values Intervention On Cold Pressor-Induced Distress Tolerance, Brooke M. Smith, Jennifer L. Villatte, Clarissa W. Ong, Grayson M. Butcher, Michael P. Twohig, Michael E. Levin, Steven C. Hayes

Psychology Faculty Publications

Research has demonstrated that values and acceptance interventions can increase distress tolerance, but the individual contribution of each remains unclear. The current study examined the isolated effect of a values intervention on immersion time in a cold pressor. Participants randomized to Values (n = 18) and Control (n = 14) conditions completed two cold pressor tasks, separated by a 30-minute values or control intervention. Immersion time increased 51.06 seconds for participants in the Values condition and decreased by 10.79 seconds for those in the Control condition. Increases in self-reported pain and distress predicted decreases in immersion time for Control, but …

Examining Quadratic Relationships Between Traits And Methods In Two Multitrait-Multimethod Models, Fredric A. Hintz

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Psychological researchers are interested in the validity of the measures they use, and the multitrait-multimethod design is one of the most frequently employed methods to examine validity. Confirmatory factor analysis is now a commonly used analytic tool for examining multitrait-multimethod data, where an underlying mathematical model is fit to data and the amount of variance due to the trait and method factors is estimated. While most contemporary confirmatory factor analysis methods for examining multi-trait multi-method data do not allow relationships between the trait and method factors, a few recently proposed models allow for the examination of linear relationships between traits …

Examining The Effect Of A School-Based Treatment On Anxiety For Latino Students, Emilie J. Larsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the efficacy of a brief culturally and instructionally modified cognitive behavioral therapy program for five anxious Latino/a youths ages 8-11 years in an elementary school setting. Each student exhibited anxiety in a classroom setting as reported by their teachers and parents or guardians. A noncurrent multiple baseline design was implemented using A-B replications to assess the effects of baseline and treatment on daily self-report student distress ratings as well as daily teacher rated distress, academic engagement, and work completion. All participants completed the Revised Children’s Manifest Anxiety Scale-2 pre- and post-treatment as well as a Children’s Intervention …

Marginal Mediation Analysis: A New Framework For Interpretable Mediated Effects, Tyson S. Barrett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mediation analysis is built to answer not only if one variable affects another, but how the effect takes place. However, it lacks interpretable effect size estimates in situations where the mediator (an intermediate variable) and/or the outcome is categorical or otherwise non-normally distributed. By integrating a powerful approach known as average marginal effects within mediation analysis—termed Marginal Mediation Analysis (MMA)—the issues regarding categorical mediators and/or outcomes are, in large part, resolved. This new approach allows the estimation of the indirect effects (those effects of the predictor that affect the outcome through the mediator) that are interpreted in the same way …

Utilizing A School-Based Treatment To Address Socially Anxious Elementary School Students, Mckell Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Despite the availability of promising clinic-based programs, youth exhibiting socially anxious behaviors rarely receive the treatment they may need. Those that do get treatment, often do so in the school setting. Thus, the demand for effective interventions to address those needs in the school-setting is growing. The present study investigated the effects of a modified CBT intervention, delivered in the school setting, on positive peer interactions and self-rating social anxiety. Results showed that the treatment package provided an increase in positive peer interactions across all four participants, as well as a decrease in self-rated anxiety behaviors.

Telepsychotherapy For The Treatment Of Trichotillomania: A Randomized Controlled Trial, Eric B. Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Trichotillomania is defined as recurrent pulling of one’s hair that results in distress and negative effects on general functioning and quality of life. Estimates of trichotillomania lifetime prevalence generally range from approximately 1% to 3% and it is likely as common as disorders such as obsessive-compulsive disorder and agoraphobia. Yet, quality treatment for trichotillomania is often difficult to find as many mental health professionals are uninformed about the disorder and its treatment. Moreover, mental health services in general are inaccessible to many with estimates suggesting that 96.5 million people do not have access to adequate services. The use of telepsychology …

Changing Nonhuman Impulsive Choice, C. Renee Renda

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Preference for smaller-sooner over larger-later rewards characterizes one type of impulsivity—impulsive choice. Impulsive choice is related to a number of maladaptive behaviors including substance abuse, pathological gambling, and poor health behaviors. As such, interventions designed to reduce impulsive choice may have therapeutic benefits. The purpose of this dissertation was to explore two methods to change nonhuman impulsive choice. In doing so, we hope to provide a baseline that future research can use to assess variables that are less amenable to human research (e.g., drug self-administration following reductions in impulsive choice). In Chapter 2, we failed to reduce nonhuman impulsive choice …

Be Cool, Stay In School: The Habits, Resources, And Confidence College Students Need To Succeed, Matthew Staheli

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Earning a college degree yields many benefits. In addition to an increased income, college degree earners generally have greater job satisfaction, make healthier life choices, are better communicators, and have greater social mobility. Even with all of these benefits, however, some colleges are seeing graduation rates as low as 32%. One of the greatest contributing factors affecting the dropout rate of undergraduate college students is poor academic performance in their courses. In this study, we sought to identify several academic resources, study behaviors, academic self-confidence scores, and demographic information to assess what types of behaviors and resources may lead to …
