Decreasing Stigma Against Depression In Chinese International Students, Elizabeth Trader Jan 2018

Decreasing Stigma Against Depression In Chinese International Students, Elizabeth Trader

Mahurin Honors College Capstone Experience/Thesis Projects

Higher levels of stress and a shift in support systems during the transition to another culture can put international students at risk for mood disorders like depression. Previous research supports there is also a higher level of depression stigma within Eastern cultures in comparison to Western cultures (Rao, Feinglass, & Corrigan, 2007). This may account for the strikingly low numbers from the Chinese population that seek and maintain professional counseling services while studying in the U.S. (Yakushko, Davidson, & Sandford-Martens, 2008). The present study sought to determine whether two self-produced Chinese videos regarding information about stigma, symptoms, and treatment of …

Pre-post evaluation was used to assess behavioral changes over a 4-month follow-up period (n = 39). The primary outcome measure was the Disruptive Behavior International Scale-Nepal version (DBIS-N). The secondary outcome scales included the Child Functional Impairment Scale and the Eyberg Child Behavior Inventory (ECBI). Twelve key informant interviews …


Is Self-Interest At The Root Of Political Behavior? An Examination Of The Effects Of Dark Personality And Demographics On Political Beliefs And Actions, Nathan A. S. Frishberg Jan 2018

Is Self-Interest At The Root Of Political Behavior? An Examination Of The Effects Of Dark Personality And Demographics On Political Beliefs And Actions, Nathan A. S. Frishberg

Theses and Dissertations

Prediction of political behavior is of interest to scientists in the fields of psychology, sociology, and politics, as well as to the lay public. Previous research has connected personality to broad political leanings, but little if any published research has examined how personality relates to voting behavior. The current study built on earlier work by examining the connections among the Dark Triad of personality (psychopathy, narcissism, and Machiavellianism), demographics, specific political beliefs, and political behaviors. We hypothesized that dark personality would relate to political beliefs such that those higher on the Dark Triad would show stronger support for policies that …


Programming To Transition Psychological Experiments From Superlab To Matlab, Mudra R. Savaliya Jan 2018

Programming To Transition Psychological Experiments From Superlab To Matlab, Mudra R. Savaliya

Undergraduate Research Posters 2018

For the past six years, our laboratory has conducted experiments programmed in Superlab, a software package designed exclusively for psychological experiments. Although Superlab has some attractive features, it also has some severe limitations. For example, Superlab cannot read files, meaning that for an experiment in which each participant has a unique stimulus list, a unique program has to be assembled for each participant. For an experiment in which each participant has a unique order of conditions, a unique program with the conditions in that order has to be assembled for each participant. Preparing numerous unique programs provides numerous opportunities for …


Perspectives On Adolescent Drug Use: Interviews With Community Providers, Noelle Naser Jan 2018

Perspectives On Adolescent Drug Use: Interviews With Community Providers, Noelle Naser

Undergraduate Research Posters 2018

With a striking rise in drug related deaths over the past few years, researchers have looked towards improving prevention methods as a way to not only react to substance abuse with treatment, but learn to better prevent individuals from following these risk taking behaviors. Adolescents specifically are prone to risk taking behaviors such as substance use as they navigate through the challenges of adolescence and transitioning into their identities. Therefore, research in understanding how and why youth decide to get involved in substances is important for creating stronger prevention. Using qualitative data obtained from semi-structured interviews with community providers (N=4), …


Perception Of Time And Post-Surgery Physical Rehabilitation, Karmen Love Jan 2018

Perception Of Time And Post-Surgery Physical Rehabilitation, Karmen Love

Undergraduate Research Posters 2018

Physical rehabilitation is an important part of a patient’s recovery after surgery. Physical therapists are crucial to the success of that patient’s healing process. Physical rehabilitation can determine how quickly the patient’s healing progresses. It is difficult to determine how long a person will be in rehab and every patient has different expectations of how long their recovery will take. In this study, I explored how a patient’s perception of time affects the estimated versus actual recovery time post-surgery. The participants were patients admitted to the inpatient rehab at Mercy Regional Medical Center in Lorain, Ohio. Each patient was assessed …


The Impact Of Adjacent-Letter Flanking Bigrams On Lexical Decision Performance, Gina M. Cascone, Deion L. Colbert Jan 2018

The Impact Of Adjacent-Letter Flanking Bigrams On Lexical Decision Performance, Gina M. Cascone, Deion L. Colbert

Undergraduate Research Posters 2018

Some models of word identification hypothesize that the word recognition system includes units responsive to bigrams (letter pairs). Grainger, Mathot, and Vitu (2014) and Palinski (2016) found that target-flanking bigrams consisting of letters adjacent in targets (e.g., OG FROG FR) affect decisions about whether letter strings are words: Bigram-letter order, but not proximity of bigram letters to their locations in the targets, affected performance. (Average performance was better with FR FROG OG and OG FROG FR than with RF FROG GO and GO FROG RF, but no different with FR FROG OG and RF FROG GO than with OG FROG …

Investigating The Electrophysiology Of Long-Term Priming In Spoken Word Recognition, Erin K. Bell Jan 2018

Investigating The Electrophysiology Of Long-Term Priming In Spoken Word Recognition, Erin K. Bell

ETD Archive

When participants are listening to the same words spoken by different talkers, two types of priming are possible: repetition priming and talker-specific priming. Repetition priming refers to the exposure of a stimulus improving responses to a subsequent exposure. Talker-specific priming refers to the exposure of words spoken by same talkers improving responses relative to those same words spoken by different talkers. There are conflicting theories regarding whether talker-specific priming should be observed. Abstract representational theories suggest that episodic details (e.g., talker identity) are not stored in the mental lexicon, while episodic theories of the lexicon posit that lexical representations include …


The Usefulness Of The Poreh Nonverbal Memory Test For The Assessment Of Response Bias, Marina Barboza Jan 2018

The Usefulness Of The Poreh Nonverbal Memory Test For The Assessment Of Response Bias, Marina Barboza

ETD Archive

In the field of neuropsychology, there is a need for reliable measures that assess for both memory and effort (response bias). A sample of college students were instructed to feign memory deficits. They were administered two well established measures of response bias, the Test of Memory Malingering (TOMM) and the Reliable Digits Span (RDS), as well as the Poreh Nonverbal Memory Test (PNMT). The study shows that all of the three measures were able to identify students who were coached to demonstrate memory deficits. A more detailed analysis showed that the TOMM and the PNMT produced higher sensitivity and specificity …

The Behavioral Immune System: Homelessness As A Disease Marker, Anya O’Connor Jan 2018

The Behavioral Immune System: Homelessness As A Disease Marker, Anya O’Connor

Departmental Honors Projects

Alongside the biological immune system is the behavioral immune system that works to avoid infection by avoiding contact with potential disease. The behavioral immune system reacts to visual cues of potential disease, such as coughing or skin lesions, and promotes avoidance behavior via disgust reactions. It interacts with biological immune responses by influencing hormones such as Interleukin-6 and cortisol. The behavioral immune system has also been found to overgeneralize and react to cues, such as obesity, disability, and foreignness, that do not signal actual disease threat. The purpose of this study is to test if the behavioral immune system overgeneralizes …

The prevalence of common mental disorders increases in humanitarian emergencies while access to services to address them decreases. Problem Management Plus (PM+) is a brief five-session trans-diagnostic psychological WHO intervention employing empirically supported strategies that can be delivered by non-specialist lay-providers under specialist supervision to adults impaired by distress. Two recent randomized controlled trials in Pakistan and Kenya demonstrated the efficacy of individuallydelivered PM+. To make PM+ more scalable and acceptable in different contexts, it is important to develop a group version as well, with 6–8 participants in session. A study is needed to demonstrate the feasibility and …


Spotlight On Once-Monthly Long-Acting Injectable Aripiprazole And Its Potential As Maintenance Treatment For Bipolar I Disorder In Adult Patients., Vanessa Torres-Llenza, Pooja Lakshmin, Daniel Z Lieberman Jan 2018

Spotlight On Once-Monthly Long-Acting Injectable Aripiprazole And Its Potential As Maintenance Treatment For Bipolar I Disorder In Adult Patients., Vanessa Torres-Llenza, Pooja Lakshmin, Daniel Z Lieberman

Psychiatry and Behavioral Sciences Faculty Publications

The lack of long-term medication adherence is a challenge in the treatment of bipolar disorder, particularly during the maintenance phase when symptoms are less prominent. The rate of nonadherence is ~20%-60% depending on how strict a definition is used. Nonadherence worsens the course of bipolar disorder and can add hundreds of thousands of dollars to the lifetime cost of treating the illness. Long-acting injectable (LAI) medication is an attractive alternative to daily dosing of oral medication, especially among patients who are ambivalent about treatment. The purpose of this paper is to review the evidence for the safety and efficacy of …


Mesotocin Influences Pinyon Jay Prosociality, J. F. Duque, W. Leichner, H. Ahmann, Jeffrey R. Stevens Jan 2018

Mesotocin Influences Pinyon Jay Prosociality, J. F. Duque, W. Leichner, H. Ahmann, Jeffrey R. Stevens

Center for Brain, Biology, and Behavior: Faculty Publications

Many species exhibit prosocial behavior , in which one individual’s actions benefit another individual, often without an immediate benefit to itself. The neuropeptide oxytocin is an important hormonal mechanism influencing prosociality in mammals, but it is unclear whether the avian homologue mesotocin plays a similar functional role in birds. Here, we experimentally tested prosociality in pinyon jays (Gymnorhinus cyanocephalus), a highly social corvid species that spontaneously shares food with others. First, we measured prosocial preferences in a prosocial choice task with two different pay-off distributions: Prosocial trials delivered food to both the subject and either an empty cage …

Investigating A Potential Relationship Between Sibling Gender Composition And Health Behavior Indicators In Young Adult And Adolescent Males, Taylor N. Goss

Honors Undergraduate Theses

The presence of siblings during childhood and adolescence has a significant impact on the behaviors and perceptions of adults later in life. Effects of mixed-gendered sibling dyads on delinquent behavior, gender typing, and romantic and sexual relationships are of interest. These behaviors can lead to notable health disparities, making it imperative to gain insight into factors associated with such behaviors in young adult and adolescent males. This project explored possible correlations between gender composition of siblings and health behavior indicators for violence, competition and risk, and sexual and romantic relationships. Analysis of these variables was performed using data from the …

Machine Learning Based Classification Of Deep Brain Stimulation Outcomes In A Rat Model Of Binge Eating Using Ventral Striatal Oscillations, Wilder Doucette, Lucas Dwiel, Jared E. Boyce, Amanda A. Simon, Jibran Y. Khokhar, Alan I. Green

Dartmouth Scholarship

Neuromodulation-based interventions continue to be evaluated across an array of appetitive disorders but broader implementation of these approaches remains limited due to variable treatment outcomes. We hypothesize that individual variation in treatment outcomes may be linked to differences in the networks underlying these disorders. Here, Sprague-Dawley rats received deep brain stimulation separately within each nucleus accumbens (NAc) sub-region (core and shell) using a within-animal crossover design in a rat model of binge eating. Significant reductions in binge size were observed with stimulation of either target but with significant variation in effectiveness across individuals. When features of local field potentials (LFPs) …

Independent And Interactive Associations Of Negative Affect, Restraint, And Impulsivity In Relation To Binge Eating Among Women, Tyler B. Mason, Kathryn E. Smith, Jason M. Lavender, Robin J. Lewis

Psychology Faculty Publications

There is growing recognition that impulsivity may serve as an underlying risk factor for binge eating. In addition, the association of impulsivity with binge eating may be moderated by other affective and cognitive risk factors. This study examined independent and interactive associations of negative affect, dietary restraint, and facets of impulsivity with binge eating. A diverse sample of 566 undergraduate women completed online questionnaires of study variables. Results revealed a three-way interaction of negative affect, dietary restraint, and attentional impulsivity in relation to binge eating. Women who were high on each of these three variables reported the greatest levels of …
