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 …

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 …

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 …

Why Do You Go To College? Shaping Student Beliefs And Success. A Dissertation Summary., Mitchell Colver

Publications

Students enter the realm of higher education with a wide variety of beliefs about the purposes of attending university, which often relate to or reveal their various motivations for pursuing a post-secondary education. Research demonstrates that some student motivations align more fully with intrinsic factors, such as the love of learning or quest for excellence, while other student motivations align with extrinsic factors, such as vocational preparedness and monetary incentives (Vallerand et al., 1989). Using a Bourdieusienne lens, this study sought to place these student motivations in the larger sociocultural context and argue for greater opportunities for democratic equity in …

Assessing Psychological Inflexibility In University Students: Development And Validation Of The Acceptance And Action Questionnaire For University Students (Aaq-Us), Michael E. Levin, Jennifer Krafft, Jacqueline Pistorello, John R. Seeley

Psychology Faculty Publications

This study sought to develop and validate a domain-specific measure of psychological inflexibility for university students, the acceptance and action questionnaire for university students (AAQ-US). Generic versions of the AAQ tend to not be as sensitive to changes in campus-specific functioning —a key outcome of interest in this population. An online survey was conducted with 425 undergraduate students. Psychometric analyses led to the refinement of a 12-item, single factor scale with strong internal consistency. Evidence for convergent validity was found with moderate to large correlations between the AAQ-US and measures of academic outcomes, mental health, and psychological inflexibility. The AAQ-US …

Opportunities For Audiologists’ To Use Patient-Centered Communication During Hearing Device Monitoring Encounters, Corinne K. Coleman, Karen F. Muñoz, Clarissa W. Ong, Grayson M. Butcher, Lauri Nelson, Michael P. Twohig

Psychology Faculty Publications

Patient-centered care incorporates patient's priorities, values, and goals. Audiologists can increase patient engagement when they use patient-centered principles during communication. Recent research, however, has revealed counseling gaps in audiology that could be detrimental to the intervention process. The present study sought to understand the extent patient-centered communication strategies were used during hearing device monitoring visits by analyzing audio recordings. Counseling portions of the appointments were transcribed using conversation analysis. Missed opportunities were observed, including not validating patients' emotional concerns, providing technical responses to emotional concerns, providing information without determining patient desire for the information, and not engaging the patient in …

The Impact Of Chronic Stress, Traumatic Experiences And Genes On Behavior, Colten Brown

Research on Capitol Hill

Chronic unpredictable stress (CUS) alters neurotransmission and remodels neural circuits involved in learning, attention and decision making.

Glial-derived neurotrophic factor (GDNF) is essential for the function of neurons. Regulation of GDNF during stress is linked to resiliency while the inability to regulate it causes behavioral alterations.

We investigated the effects of CUS on latent inhibition (LI), a measure of selective attention expressed in this model as freezing behavior.

The Role Of Experiential Avoidance In Problematic Pornography Viewing, Michael E. Levin, Eric B. Lee, Michael P. Twohig

Psychology Faculty Publications

Research suggests that online pornography use can have harmful consequences for some individuals, but the psychological processes that contribute to problematic viewing are unclear. This study sought to evaluate the role of experiential avoidance in the negative consequences of online pornography viewing in a small cross sectional survey sample of 91 male college students who reported viewing. Results indicated that viewing pornography for experientially avoidant motivations was related to more frequent viewing and predicted self-reported negative consequences of viewing over and above other motivations (e.g., sexual pleasure, curiosity, excitement seeking). Although more frequent viewing was related to more self-reported negative …

How Internalized Sexism Impacts Young Adult Women And Their Sociopolitical Behavior, Audrianna Dehlin

Research on Capitol Hill

Sexism: A belief, practice, or system that supports the idea that the male sex is intrinsically superior to the female sex.

• The two major types of sexism are hostile and benevolent.
• In addition to external experiences of sexism, these beliefs can be internalized by women and are linked to negative outcomes.
• The overall climate surrounding women's issues is becoming more contentious.
• Because of this, research and conversation surrounding gender equality are in the mainstream consciousness.
• This study used a correlational design to examine the relationship between internalized sexism, psychological health, relationship satisfaction, political affiliation, voting patterns, religious fundamentalism, social desirability, …

The Effects Of Nicotine On Maladaptive Alcohol Drinking, Isabella Stuart

Research on Capitol Hill

• Impulsivity is defined as choosing a smaller-sooner choice over a more rational larger-later choice.
• Most delay discounting studies only investigate magnitude differences in the same reward.
• Cross-commodity discounting consists of providing the opportunity for subjects to choose between a low quality reward that is available almost immediately and a higher quality reward that is available at a time delay. We will model this in an animal model with rats who have a choice between a relatively small amount of alcohol immediately and a relatively large amount of food at a delay.

The Role Of Multiple Internal Timekeepers And Sources Of Feedback On Interval Timing, Breanna E. Studenka, Daisha L. Cummins, Megan A. Pope

Kinesiology and Health Science Faculty Publications

The aim of this experiment was to document the role of multiple internal clock mechanisms and external sources of temporal feedback on reducing timing variability when two fingers tap instead of one (a phenomenon known as the bimanual advantage). Previous research documents a reduction in timed interval variability when two effectors time instead of one. In addition, interval variability decreases with multiple sources of feedback. To date, however, no research has explored the separate roles of feedback and internal timing on the bimanual advantage. We evaluated the bimanual advantage in a task that does not utilise an internal clock (circle …

Performance Feedback To Increase Use Of Counseling Skills, Jalin K. Finai, Karen F. Muñoz, Clarissa W. Ong, Grayson M. Butcher, Lauri Nelson, Michael P. Twohig

Psychology Faculty Publications

Counseling is a critical component of audiological care and when implemented purposefully can yield multiple benefits for patients. Professional guidelines indicate that counseling is within the scope of practice for audiologists, yet research has shown that audiologists feel unprepared and are not comfortable providing adjustment counseling. This may be due to inadequate counseling training in audiology graduate programs. To identify ways to address this counseling training gap, this study examined the use of performance feedback to increase counseling skills among audiology graduate students. In this study, participants (n = 5) were recorded during clinical session encounters, and recordings were …

Acceptance And Commitment Therapy For A Case Of Scrupulosity-Related Obsessive-Compulsive Disorder, Eric B. Lee, Clarissa W. Ong, Woolee An, Michael P. Twohig

Psychology Faculty Publications

Acceptance and Commitment Therapy (ACT) is a modern form of Cognitive Behavior Therapy (CBT) with growing support for treating obsessive-compulsive disorder (OCD). We present a case wherein a client presented with scrupulosity-related OCD. We briefly review scrupulosity, explain the theory behind ACT, and present a case, the treatment process, and desired outcomes. Exposure and response prevention (ERP) is described from an ACT perspective and discussed as an option for people with OCD who may be reluctant to engage in more traditional forms of ERP.

Tailoring Acceptance And Commitment Therapy Skill Coaching In-The-Moment Through Smartphones: Results From A Randomized Controlled Trial, Michael E. Levin, Jack Haegar, Rick A. Cruz

Psychology Faculty Publications

There is growing evidence for the efficacy of acceptance and commitment therapy (ACT) interventions delivered through smartphones, but research has not yet focused on how to optimize such interventions. One benefit of mobile interventions is the ability to adapt content based on in-the-moment variables. The current randomized controlled trial evaluated whether an ACT app that tailored skill coaching based on in-the-moment ecological momentary assessments (EMAs) would be more efficacious than the same app where skill coaching was random or an EMA-only condition. A sample of 69 adults interested in using a self-help app were randomized to one of three app …

Persistence And Relapse Of Reinforced Behavioral Variability, Ann Galizio, Charles C. J. Frye, Jeremy M. Haynes, Jonathan E. Friedel, Brooke M. Smith, Amy L. Odum

Psychology Faculty Publications

The present study examined persistence and relapse of reinforced behavioral variability in pigeons. Pigeons emitted four‐response sequences across two keys. Sequences produced food according to a lag schedule, in which a response sequence was followed by food if it differed from a certain number of previous sequences. In Experiment 1, food was delivered for sequences that satisfied a lag schedule in both components of a multiple schedule. When reinforcement was removed for one component (i.e., extinction), levels of behavioral variability decreased for only that component. In Experiment 2, food was delivered for sequences satisfying a lag schedule in one component …

Scaling Out Evidence-Based Interventions Outside The U.S. Mainland: Social Justice Or Trojan Horse?, Melanie M. Domenech-Rodriguez, Ana A. L. Baumann, Alejandro L. Vázquez, Nancy G. Amador-Buenabad, Natalie Franceschi Rivera, Nydia Ortiz-Pons, J. Rubén Parra-Cardona

Psychology Faculty Publications

Global health disparities continue to widen as professional standards for effectiveness of mental health services provision become more precise and difficult to achieve across varied economic and social contexts. Within the U.S., health disparities are evident in Latinx populations. Globally, the health disparities are also evident in Latin America as compared to the U.S. and other economically affluent nations. The diversification of psychology in content and persons has led to a unique opportunity to build bridges that can help reduce disparities in- and outside of the U.S. mainland. Collaborations can be of great use in addressing health disparities internationally but …
