Task-Evoked Pupillary Response For Completely Intelligible Accented Speech, Drew Mclaughlin Aug 2019

Task-Evoked Pupillary Response For Completely Intelligible Accented Speech, Drew Mclaughlin

Arts & Sciences Graduate Student Theses and Dissertations

Speech perception under adverse conditions, such as those caused by noise in the environment or a speaker’s accent, can be cognitively demanding. For second language- (L2-) accented speech, mismatches between the speech patterns of an L2-accented speaker and a listener can result in poorer understanding and reduced intelligibility (i.e., fewer words in the speech stream can be correctly identified). However, it remains unclear whether completely intelligible L2-accented speech imposes greater cognitive load (defined here as the degree to which cognitive resources are recruited at a given moment to meet processing demands) than native speech. In the current study, we used …


Improving Procedural Fidelity And Treatment Outcome In Natural Environment Training Using Peer Feedback, Kara Shawbitz Aug 2019

Improving Procedural Fidelity And Treatment Outcome In Natural Environment Training Using Peer Feedback, Kara Shawbitz

All NMU Master's Theses

Procedural fidelity as it relates to client outcomes is a topic of growing interest in applied behavior analysis. Behavior analytic treatments are implemented by Registered Behavior Technicians (RBTs). The current requirements for the RBT credential is a forty hour training and a 75 question examination. However, research has shown that immediately following training, procedural fidelity decreases. Many methods have been tried to improve procedural fidelity following training, including performance feedback. The present study evaluated the effect of peer feedback immediately following a natural environment training (NET) session and peer feedback immediately preceding the next opportunity. For all three of the …


Players' Preference For Losses Disguised As Wins In Keno: A Concurrent Choice Procedure, Sarah Hall Aug 2019

Players' Preference For Losses Disguised As Wins In Keno: A Concurrent Choice Procedure, Sarah Hall

All NMU Master's Theses

Roughly 3% of American citizens are considered to be problem gamblers (NCPG, 2014). This compulsion can have a detrimental impact on the pathological gambler’s life. One factor that has been considered to lead to this compulsive gambling is the loss disguised as a win (LDW). These LDWs have been shown to increase slot machine playing in numerous studies. However, their effect has not been studied in connection to Club Keno, which is also a highly prevalent game. In 2017 the Michigan lottery took in over $600 million in revenue from Club Keno (FGSAD, 2017). The present study sought to determine …


Assessment Of Sex Differences And Amphetamine On Schedule-Induced Polydipsia, Min Park Aug 2019

Assessment Of Sex Differences And Amphetamine On Schedule-Induced Polydipsia, Min Park

All NMU Master's Theses

Amphetamine (AMPH) is one of the most common psychotropic drugs abused in the United States. Its major pharmacological effect is to increase synaptic dopamine levels in the mesolimbic reward pathway, which in turn causes behavioral effects in animals, and subjective effects in humans. These reinforcing properties of AMPH trigger very strong levels of craving the drug, and eventually result in patterns of compulsive use of AMPH. Regarding psychostimulant action, female rats have been reported to be more vulnerable to the reinforcing effects of psychostimulants. In the current study, schedule-induced polydipsia (SIP), an animal model of compulsive behavior, was applied for …


Do Psychopathic Traits Influence Distractibility By Empathy-Eliciting Pictures?, Priya M. Reji Aug 2019

Do Psychopathic Traits Influence Distractibility By Empathy-Eliciting Pictures?, Priya M. Reji

Student Theses

Empathy is a crucial component in forming interpersonal connections, and reflects the ability to share and understand the feelings of others. Psychopathy is often associated with a reduced ability to feel and display empathetic concern towards other people. The Response Modulation Hypothesis argues that such individuals have an attentional deficit, which makes it difficult for them to shift focus between stimuli, thus individuals who have high scores on the interpersonal-affective factor of psychopathy have an increased ability to ignore emotional stimuli that are goal-irrelevant. The current study investigated whether psychopathic traits would influence distractibility on an emotional Stroop (eStroop) task. …


Factors Influencing The Use Of Cognitive-Behavioral Therapy With Autistic Adults: A Survey Of Community Mental Health Clinicians, Brenna B. Maddox, Samantha Crabbe, Jessica Fishman, Rinad S. Beidas, Lauren Brookman-Frazee, Judith Miller, Christina Nicolaidis, David Mandell Aug 2019

Factors Influencing The Use Of Cognitive-Behavioral Therapy With Autistic Adults: A Survey Of Community Mental Health Clinicians, Brenna B. Maddox, Samantha Crabbe, Jessica Fishman, Rinad S. Beidas, Lauren Brookman-Frazee, Judith Miller, Christina Nicolaidis, David Mandell

School of Social Work Faculty Publications and Presentations

Cognitive–behavioral therapy (CBT) can improve anxiety and depression in autistic adults, but few autistic adults receive this treatment. We examined factors that may influence clinicians’ use of CBT with autistic adults. One hundred clinicians completed an online survey. Clinicians reported stronger intentions (p = .001), more favorable attitudes (p < .001), greater normative pressure (p < .001), and higher self-efficacy (p < .001) to start CBT with non-autistic adults than with autistic adults. The only significant predictor of intentions to begin CBT with clients with anxiety or depression was clinicians’ attitudes (p < .001), with more favorable attitudes predicting stronger intentions. These findings are valuable for designing effective, tailored implementation strategies to increase clinicians’ adoption of CBT for autistic adults.

Autistic adults have high rates of anxiety and depression (Buck et al. 2014; Croen et al. 2015), and often do not receive quality mental healthcare for these or other co-occurring conditions (Maddox et al. 2019; Roux et al. 2015; Shattuck et al. …


Peer-Mediated Tootling With A Standardized Form And A Mystery Motivator In High School Classrooms, Sarah J. Wright Aug 2019

Peer-Mediated Tootling With A Standardized Form And A Mystery Motivator In High School Classrooms, Sarah J. Wright

Dissertations

Peer-mediated tootling with a standardized procedure was implemented along with a mystery motivator component to determine the effects on academically engaged and disruptive behavior in three general education high school classrooms. The intervention used an A/B/A/B design across all classrooms. The goal of the study was to determine if these components would increase academically engaged behavior and decrease disruptive behavior. Students were trained on tootling procedures with a standardized format, which included reporting on peers’ positive, prosocial behavior on a premade tootling slip with various behaviors that they could select as being observed, reading five random slips aloud, totaling the …


Profiles Of Interest In Holland's Theory In Relation To Personality And Sex, Erica L. Mathis Aug 2019

Profiles Of Interest In Holland's Theory In Relation To Personality And Sex, Erica L. Mathis

Dissertations

The current study sought to expand the knowledge of latent profiles of vocational interest that are interpreted from a theory-driven perspective. The current study utilized a measure of Holland’s RIASEC interest types as a source of data to explore possible profiles through latent profile analysis. Using an MTurk sample of 303 adults, seven profiles were interpreted in the context of Holland’s theory, specifically using diagnostic signs of the theory to explain possible profile membership. The seven profiles were coined Low Profile Elevation, High Consistency SIA, Moderate Consistency Conventional Investigative, Undifferentiated, High Differentiation Conventional Dominant, High Consistency Investigative Artistic, and High …


Evaluation Of A Role-Playing Game To Improve Social Skills For Individuals With Asd, Kate A. Helbig Aug 2019

Evaluation Of A Role-Playing Game To Improve Social Skills For Individuals With Asd, Kate A. Helbig

Dissertations

Autism spectrum disorder (ASD) affects one in 59 children (Centers for Disease Control and Prevention, 2018). Impairments in social communication and restricted and repetitive behaviorsare often associated with debilitating outcomes for individuals with ASD. Therefore, it is critical to identify successful treatments to address the social deficits characteristic of ASD. This study investigated the effects of a role-playing game (RPG) on social skill acquisition for individuals with ASD. The primary dependent variable was skill acquisition within the context of the RPG setting. Generalization of skill acquisition outside of the game-context and social functioning was also evaluated. Results indicated that the …


Validation Of The Ask-Asd In A Sample Of Parents, Teachers, And Medical Students, Laura K. Hansen Aug 2019

Validation Of The Ask-Asd In A Sample Of Parents, Teachers, And Medical Students, Laura K. Hansen

Dissertations

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that begins in childhood and manifests in social communication impairment and restricted, repetitive behaviors (American Psychiatric Association, 2013). Although accurate information about ASD is available through a variety of sources, this access to information may not translate into increased knowledge in parents, teachers, and medical professionals. A Survey of Knowledge of Autism Spectrum Disorder (ASK-ASD) was initially established as a reliable, valid measure of perceived and actual knowledge of ASD (Hansen, 2015). The current study evaluated the psychometric properties (i.e., factor structure, reliability, and validity) of the ASK-ASD in a sample of …


The Relationship Between Painful/Provocative Training Experiences And Capability For Suicide Among Medical Students, Brittney L. Assavedo Aug 2019

The Relationship Between Painful/Provocative Training Experiences And Capability For Suicide Among Medical Students, Brittney L. Assavedo

Dissertations

The primary aim of this study was to examine the relationship between capability for suicide and painful and provocative experiences related to practicing within the medical profession (mPPEs) among students enrolled in a College of Osteopathic Medicine (n = 114). It was posited that frequency of engagement in mPPEs would predict scores on measures of capability for suicide above and beyond the effects of gender and painful and provocative experiences unrelated to practicing within the medical profession (PPEs). It was also posited that frequency of both witnessing and performing an mPPE would moderate the impact of curriculum component on capability …


Dependability Of Two Group Observation Methods Across Rater And Time, Kayla E. Bates-Brantley Aug 2019

Dependability Of Two Group Observation Methods Across Rater And Time, Kayla E. Bates-Brantley

Dissertations

Collecting efficient and reliable behavior assessment data is often a goal for school districts and school psychologists. Unfortunately, the most accurate methods of behavior observations, systematic direct observations (SDO), can be time-intensive and often requires specific training. This often minimizes the number of trained professional available for observation procedures. Planned activity check (PAC), a variation of momentary time sampling, has the potential to combine the accuracy of SDO with efficiency. However, few studies have evaluated the psychometric principals of PAC. The current study sought to evaluate the reliability and dependability of PAC by comparing PAC to an individual-fixed (I-F) SDO. …


Weeding Through College Drinking: The Moderating Role Of Marijuana Use On Alcohol Use, Protective Behavioral Strategies, And Negative Consequences, Mallorie Carroll Aug 2019

Weeding Through College Drinking: The Moderating Role Of Marijuana Use On Alcohol Use, Protective Behavioral Strategies, And Negative Consequences, Mallorie Carroll

Dissertations

Rates of alcohol (60% monthly) and marijuana (20% monthly) use among college students remain a concern given students experience a wide range of negative consequences related to their use, especially hazardous use. Research supports the theory that protective behavioral strategies are effective strategies that one can use while engaging in alcohol and marijuana use to minimize the experience of negative consequences. However, research regarding protective behavioral strategies for marijuana is fairly new and the findings are inconsistent. Given the limited research regarding alcohol-use behaviors among college students who report alcohol and marijuana use, the purpose of this study was to …


Overparenting And Young Adult Narcissism: Psychological Control And Interpersonal Dependency As Mediators, Nathan Alexander Winner Aug 2019

Overparenting And Young Adult Narcissism: Psychological Control And Interpersonal Dependency As Mediators, Nathan Alexander Winner

Dissertations

Overparenting, or “helicopter parenting,” is a unique style of parenting characterized by parents’ well-intentioned but age-inappropriate over-involvement and intrusiveness in their children’s lives. Recent research has linked overparenting to the development of narcissistic traits in young adults, although the mechanisms of this relationship remain unclear. Two plausible mechanisms include the parenting behavior of psychological control and the increased interpersonal dependency of the child. Psychological control is a construct that overlaps with overparenting and has been linked to both dependent and narcissistic traits. Similarly, interpersonal dependency is a key predictor of narcissistic traits. Therefore, the present study sought to examine psychological …


"We've Been Here All Along" : The Standpoint And Collective Resilience Of Transgender U.S. Service Members., Jacob R. Eleazer Aug 2019

"We've Been Here All Along" : The Standpoint And Collective Resilience Of Transgender U.S. Service Members., Jacob R. Eleazer

Electronic Theses and Dissertations

The 2010 repeal of the Don’t Ask, Don’t Tell (DADT) policy ended the ban on open lesbian, gay, and bisexual (LGB) military service (Alford & Lee, 2016). However, prior to 2015 transgender military personnel were still considered medically and psychologically unfit for service (Kerrigan, 2012; Yerke & Mitchell, 2013). From 2015 through 2017, the Department of Defense (DoD) researched the implications of policy change, developed new policies and trainings, and implemented open service for transgender persons (Belkin, 2016; Carter, 2015). The purpose of this study was to explore the experiences of transgender military service members prior to this transition in …


Behavioral And Cognitive Correlates Of Intolerance Of Uncertainty In Children With And Without Anxiety Disorders., Colette Marie Gramszlo Aug 2019

Behavioral And Cognitive Correlates Of Intolerance Of Uncertainty In Children With And Without Anxiety Disorders., Colette Marie Gramszlo

Electronic Theses and Dissertations

Intolerance of Uncertainty (IU) has long been identified as a proximal risk factor for the development of anxiety disorders, and more recently has been implicated in the development of emotional disorders broadly. However, little is known about how IU and psychopathology symptoms relate, limiting the degree to which IU can be identified prior to the development of emotional disorders and targeted during the intervention of disorder symptoms. The current study reviews several areas of literature to inform a model by which IU impacts anxiety symptoms. First, uncertainty processing and the development of uncertainty processing in childhood are reviewed. Next, IU …


An Integrated Model Of Eating Disorder Risk And Protective Factors: Implications For Research And Treatment, Leslie Alison Davis-Waddle Aug 2019

An Integrated Model Of Eating Disorder Risk And Protective Factors: Implications For Research And Treatment, Leslie Alison Davis-Waddle

Electronic Theses and Dissertations

Body dissatisfaction and disordered eating behaviors are significant public health concerns, especially among college-age women. Despite extensive research, the complex nature of disordered eating and its etiology has prevented a satisfactory predictive model from being developed and validated and has therefore hindered the development of effective prevention and intervention strategies. This study aimed to integrate four of the most common etiological theories into a model to predict disordered eating behaviors. Bivariate correlations and moderation analyses were conducted to determine the strength of relationships between variables and to determine whether a protective factor (i.e., self-compassion) moderates the effects of risk factors …


A Tactful Conceptualization Of Joint Attention: Joint Haptic Attention And Language Development, Lauren P. Driggers-Jones Aug 2019

A Tactful Conceptualization Of Joint Attention: Joint Haptic Attention And Language Development, Lauren P. Driggers-Jones

Electronic Theses and Dissertations

Research investigating associations between joint attention and language development have thus far only investigated joint attention by way of visual perceptions while neglecting the potential effects of joint attention engaged through other sensory modalities. In the present study, I aimed to investigate the joint attention-language development relationship by investigating the possible links between joint haptic attention and language development, while also exploring the likely contributions of joint visual attention through a mediation analysis. Using video recordings from an archival dataset, measures of joint haptic attention and joint visual attention were derived from behavioral tasks, and measures of vocabulary development were …


Resilience Among Survivors Of Adverse Childhood Experiences In Appalachia, Bridget Jeter Aug 2019

Resilience Among Survivors Of Adverse Childhood Experiences In Appalachia, Bridget Jeter

Electronic Theses and Dissertations

The empirical investigation of adverse childhood events (ACEs) and their relationship with health and well-being outcomes in later life is increasing. Less is known about factors that may promote resilience for those who have survived such challenges, such as how resilience may be facilitated for those with ACEs residing in a marginalized region such as South Central Appalachia. Multidimensional spirituality, social support, stigma related to ACEs, and Appalachian acculturation may serve as both valid cultural factors and potential indicators of resilience. Cross-sectional, simultaneous multiple regression analysis was performed on data collected from 272 adult patients of a South Central Appalachian …


Impact Of Adverse Childhood Experiences On Mental Health Outcomes And Related Prescription Practices In A Psychiatric Inpatient Sample, Carrie Lemay Aug 2019

Impact Of Adverse Childhood Experiences On Mental Health Outcomes And Related Prescription Practices In A Psychiatric Inpatient Sample, Carrie Lemay

Electronic Theses and Dissertations

A definitive association between adverse childhood experiences (ACEs) and negative physical and mental health outcomes has been established. There is evidence that individuals in forensic psychiatric facilities are disproportionately exposed to ACEs, which may impact severity, prognosis, and age of onset of psychiatric symptoms, including behavioral concerns of institutional aggression, self-harm behaviors, and suicide attempts. Such psychiatric and behavioral concerns are often managed through multiple psychotropic prescriptions, leading to psychotropic polypharmacy. This study evaluated the relationship between ACEs, mental health and behavioral concerns, and psychotropic polypharmacy through analysis of archival data from a forensic inpatient psychiatric facility. A total of …

The Relationship Between Frequency Of Yoga And Meditation On Ptsd Symptoms In Individuals Who Have Experienced Intimate Partner Violence, Kimberly Polignani

Dissertations

Intimate partner violence (IPV) has become a growing phenomenon in the United States,

affecting nearly 13% of the population. The adverse mental health outcomes from people who experience IPV are prevalent and more than half have a diagnosis of posttraumatic stress disorder (PTSD). Therefore, therapeutic techniques for PTSD appear to be feasible for IPV survivors and their mental health issues. Complementary and alternative medicine has become a widely accepted approach for PTSD. Being two complementary and alternative medicine techniques, yoga and meditation are effective forms of therapy in many diagnoses, including PTSD. This study utilized a not-for-profit organization called the …


The Underlying Psychophysiology Of Pedophilic Disorder And The Implications For Treatment Approaches, Tonise Florexil Aug 2019

The Underlying Psychophysiology Of Pedophilic Disorder And The Implications For Treatment Approaches, Tonise Florexil

Dissertations

Sexual crimes are a persistent and significant social dilemma that continues to plague our society (Lee, Jackson, Pattison, & Ward,2002). Past research has made considerable advancements in terms of the types of interventions that clinicians can utilize when they work with individuals who have a history of child sexual offenses. However, current literature lacks an understanding of the risk factors that influence the development of Pedophilic Disorder. A history of sexual trauma also affects families. The children of traumatized individuals have more adjustment difficulties than their counterparts who did not have a parent(s) with a sexual trauma history. This clinical …

The Use Of An Individualized Levels System And Extinction To Increase Task Compliance And To Decrease Aggressive Behavior With A Child With Autism, Savanna A. Chojnacki Aug 2019

The Use Of An Individualized Levels System And Extinction To Increase Task Compliance And To Decrease Aggressive Behavior With A Child With Autism, Savanna A. Chojnacki

Graduate Theses/Dissertations

In a token economy level system, as an individual progresses from one task level to the next, there is an increase in the demand of tasks and an increase in the magnitude of reinforcers earned. The motivation for the individual in level systems stems from the increasing of value of reinforcers earned at each level. In this study a level system in concordance with an extinction procedure for aggressive behaviors was employed as a behavioral intervention. In this single-subject design study, a 5-year-old boy with autism was observed across a variety of 15 minute teaching sessions, implementing synchronously, the reinforcement …


Expertise Within Working Memory And Fluid Intellgence, Addie Wikowsky Aug 2019

Expertise Within Working Memory And Fluid Intellgence, Addie Wikowsky

Graduate Theses/Dissertations

Working memory, fluid intelligence, and expertise are all psychological concepts that have been explored in the field. Working memory, defined by Baddeley (1986), is the temporary storage of stimuli presented to a person. The relationship between working memory and fluid intelligence is a common theme among studies. Fluid intelligence is one of the components of general intelligence (g). Specifically, fluid intelligence can be described as being able to adapt thinking, even with no previous knowledge (Jaeggi, Buschkuehl, Jonides, & Perrig, 2008). Expertise is another critical factor in these studies and is the acquisition of knowledge and being able to apply …

Graduate Theses/Dissertations

The purpose of the present study was to explore differences and similarities in multiple aspects of male body image across age groups, including body dissatisfaction, coping strategies, functional appreciation, and mood. It was first hypothesized that younger men would report greater dissatisfaction with muscularity and body fat than middle-aged and older men. The second hypothesis stated that body dissatisfaction would predict depressive symptoms. The third hypothesis predicted that age and functionality appreciation for the body would be positively correlated. Finally, researchers evaluated the relationship between body image coping strategies and age from an exploratory perspective. Participants included 344 men ages …


Yoga To Decrease The Stress Response: Gentle Yoga Encourages Faster Decline In Salivary Cortisol Concentrations Following Participation In Tsst, Tabetha Gaile Hopke Aug 2019

Yoga To Decrease The Stress Response: Gentle Yoga Encourages Faster Decline In Salivary Cortisol Concentrations Following Participation In Tsst, Tabetha Gaile Hopke

Graduate Theses/Dissertations

Short-term, activation of the human stress response system is beneficial as it prepares the body to deal with stressors at hand (McEwen & Stellar, 1993). If this system is overactive or chronically active however, it can negatively impact health and longevity (Cohen, Janicki-Deverts, & Miller, 2007). According to a review conducted by Ross & Thomas (2010) implementation of a yoga practice has been shown to down-regulate the stress response system. The present study aimed to expand on current research involving yoga for stress reduction by exploring whether participation in gentle yoga could decrease the stress response more quickly than naturally …

Olson, Bruce F. Pennington, Shelley D. Smith, Joan Bosson-Heenan, Jeffrey R. Gruen

Psychology: Faculty Scholarship

Background: Rapid automatised naming (RAN) and rapid alternating stimulus (RAS) are reliable predictors of reading disability. The underlying biology of reading disability is poorly understood. However, the high correlation among RAN, RAS and reading could be attributable to shared genetic factors that contribute to common biological mechanisms.

Objective: To identify shared genetic factors that contribute to RAN and RAS performance using a multivariate approach.

Methods: We conducted a multivariate genome-wide association analysis of RAN Objects, RAN Letters and RAS Letters/Numbers in a sample of 1331 Hispanic American and African-American youth. Follow-up neuroimaging genetic analysis of cortical regions associated with reading …
