Resting-State Functional Connectivity In Youth With Gender Dysphoria, Felix L. Garcia Sep 2018

Resting-State Functional Connectivity In Youth With Gender Dysphoria, Felix L. Garcia

Dissertations, Theses, and Capstone Projects

Current developmental models of gender identity and gender dysphoria (GD) lack sex-specific profiles of brain function that differentiate between typically-developing and cross-gender identified youth, as postulated by models like the unified theory of the origins of sex differences (Arnold, 2009) and the neurobiological theory of the origins of transsexuality (Swaab & Garcia-Falgueras, 2009). Previously, investigators have used brain imaging modalities such as Resting-State functional Magnetic Resonance Imaging (R-fMRI) to demonstrate differences in resting-state functional connectivity (RSFC) between typically-developing male and female youth, and between typically-developing and GID-diagnosed youth. In the present pilot study, I used R-fMRI to investigate differences in …


Casualties Of Racism: Racial And Ethnic Discrimination And Suicidal Thoughts And Behaviors Among Racial And Ethnic Minority Emerging Adults, Lillian Anais Polanco Sep 2018

Casualties Of Racism: Racial And Ethnic Discrimination And Suicidal Thoughts And Behaviors Among Racial And Ethnic Minority Emerging Adults, Lillian Anais Polanco

Dissertations, Theses, and Capstone Projects

The evidence demonstrating that experiences of racial/ethnic discrimination is detrimental to the mental health of racial/ethnic minority youth is unequivocal. What remains unclear, however, is whether racial/ethnic discrimination increases vulnerability for suicidal thoughts and behaviors in particular, and if so, what are the underlying mechanisms to explain this relation. Drawing upon the Race-based Traumatic Stress Theory (Carter, 2007), which suggests that some individuals may experience racial/ethnic discrimination as a traumatic stressor, and thus, eliciting a traumatic stress response, the present study examined posttraumatic stress reactions (i.e., posttraumatic stress, depression, dissociation, stress sensitivity) as mediators in the relation between racial/ethnic discrimination …


The Effect Of A Voice Treatment On Facial Expression In Parkinson’S Disease: Clinical And Demographic Predictors, Amanda D. Bono Sep 2018

The Effect Of A Voice Treatment On Facial Expression In Parkinson’S Disease: Clinical And Demographic Predictors, Amanda D. Bono

Dissertations, Theses, and Capstone Projects

Parkinson’s disease (PD) is a neurodegenerative disease associated with a wide range of motoric, cognitive, and behavioral symptoms. Impairments in facial mobility and emotional expressivity are common and can impair communication, in turn, affecting daily functioning and quality of life. Previous research suggests that the Lee Silverman Voice Treatment © (LSVT LOUD; Ramig et al., 2001, 2011) increases vocal loudness and facial expressivity in individuals with PD compared to PD and healthy controls. This study extends the literature by examining the effects of LSVT and an articulation-based control treatment (i.e., ARTIC) on multiple aspects of facial expressivity (i.e., emotional frequency …


Linking Hostile/Helpless Maternal Representations In Pregnancy And Later Child Protection Involvement: A Pilot Study, Madeleine Terry Sep 2018

Linking Hostile/Helpless Maternal Representations In Pregnancy And Later Child Protection Involvement: A Pilot Study, Madeleine Terry

Dissertations, Theses, and Capstone Projects

The present pilot study examined whether there are reliable indices in the narratives of pregnant women that can be used to identify child abuse and neglect potential before the birth of the child. The Hostile/Helpless (HH) Classification system (Lyons-Ruth et al., 1995-2005), which detects mental states associated with trauma, disturbances in early attachment, and severe pathology, was adapted for use with the Pregnancy Interview (PI), a semi-structured clinical interview (Slade, 2003) that assesses a woman's emotional experience of pregnancy, and quality of her developing relationship with her baby. The study sample was drawn from a replication study of the Minding …


Underlying Contribution Of Executive Functioning To Cognition And Academic Achievement In Individuals With Dystrophinopathy, Robert Fee Sep 2018

Underlying Contribution Of Executive Functioning To Cognition And Academic Achievement In Individuals With Dystrophinopathy, Robert Fee

Dissertations, Theses, and Capstone Projects

Dystrophinopathy is a genetic disorder that results in the lack of or abnormal expression of the protein dystrophin. It is a disorder that alters cell structure and function, impacts the developing brain and brain function, presents with multi-domain cognitive deficits, and influences both mood and behavior. Cognitive impairments appear to be more localized to specific areas of functioning rather than a global deficit; however, deficits have been identified across multiple cognitive domains including language and aspects of executive functioning. A careful examination of the cognitive phenotype and its association to mutations affecting CNS isoforms is necessary to clarify the neuropsychological …


What’S Your Story? Assessing Childhood Maltreatment Using The Thematic Apperception Test In An Adult Inpatient Population., Thachell C. Tanis Sep 2018

What’S Your Story? Assessing Childhood Maltreatment Using The Thematic Apperception Test In An Adult Inpatient Population., Thachell C. Tanis

Dissertations, Theses, and Capstone Projects

There is a robust evidence that childhood maltreatment contributes to the development of adult psychopathology (Brown & Anderson, 1991; Johnson, Cohen, Brown, Smailes, & Bernstein 1999; Johnson, Smailes, Cohen, Brown, & Bernstein, 2000; Ruggiero et al., 1999). However, the identification of childhood maltreatment remains a methodological problem that results in inconsistencies in the reported incidence and psychological sequelae of maltreatment. A primary method for identifying histories of childhood maltreatment among adults is retrospective self-report measures which are susceptible to multiple biases (Briere, 1992; Cicchetti & Rizley, 1981; Shaffer, Huston, & Egeland, 2008). This present study suggests that childhood maltreatment can …


Stereotype Threat As An Explanation For Sexual Risk Taking Behavior In Gay Men: A Multi-Study Exploration Of Mechanisms, Inna Saboshchuk Sep 2018

Stereotype Threat As An Explanation For Sexual Risk Taking Behavior In Gay Men: A Multi-Study Exploration Of Mechanisms, Inna Saboshchuk

Dissertations, Theses, and Capstone Projects

Stereotype threat is a hindrance in performance that occurs when an individual’s awareness of negative stereotypes associated with his/her group results in inadvertent conforming to that stereotype. Stereotype threat research has been conducted on myriad group and domain identifications but gay men are strikingly absent from the stereotype threat literature. One of the most prevalent stereotypes about gay men indicates they are sexually promiscuous and that this promiscuity is linked to HIV infection. In a series of three research projects, a theoretical model proposing stereotype threat as a mechanism for sexual risk taking behavior in gay men is tested. In …


Curcumin Inhibits The Ikk:Nf-Kappa B Pathway In Neural Fear Circuits, Miguel A. Briones Sep 2018

Curcumin Inhibits The Ikk:Nf-Kappa B Pathway In Neural Fear Circuits, Miguel A. Briones

Dissertations, Theses, and Capstone Projects

The study of how the brain acquires fearful memories has attracted considerable experimental attention, due in part to the promise of discovering novel therapeutic approaches for psychiatric disorders that are characterized by unusually strong and persistent traumatic memories. In recent years, extensive research has focused on studying the neural and molecular mechanisms by which fear memories are acquired, stored, and retrieved in the brain. Once acquired, fear memories may be attenuated using one of 2 procedures: 1) fear extinction, which involves repeated presentation of the fear-arousing stimulus in the absence of an aversive consequence, or 2) interference with the reconsolidation …


Dancing, Mindfulness, And Our Emotions: Embracing The Mind, Body, And Sole, Alisha M. Collins May 2018

Dancing, Mindfulness, And Our Emotions: Embracing The Mind, Body, And Sole, Alisha M. Collins

Dissertations, Theses, and Capstone Projects

This capstone project examines dance, as an intervention and mindfulness practice that assists with managing our emotions. There is a need for dance therapy in social institutions such as, healthcare facilities, schools, and community centers. Dance therapy has the potential to reduce negative emotions, create mindfulness, improve self-expression, and promote a healthy well-being. I am proposing that dance therapy is applied as a regular practice in social institutions to develop mindfulness and promote emotional stability.

In this study, I argue that dance therapy can contribute to our well-being long term. In addition to this written thesis, a visual component of …


Assessing The Ordinality Of Response Bias With Item Response Models: A Case Study Using The Phq-9, Venessa N. Singhroy May 2018

Assessing The Ordinality Of Response Bias With Item Response Models: A Case Study Using The Phq-9, Venessa N. Singhroy

Dissertations, Theses, and Capstone Projects

Improper scale usage in psychological and clinical assessment is an important problem. If respondents do not use the scales in a consistent manner, the reliability of a composite is likely to be attenuated. This is particularly problematic when particular items are singled out for special treatment or when subscales are of interest, not just a total score. This study used both non-parametric and parametric item response theory (IRT) methods to gain further insight into the validity of the PHQ-9, a dual purpose instrument that assesses the severity of depressive symptoms using nine Likert-scale items and allows the investigator to establish …


Psychosocial Correlates Of Post-Traumatic Stress Disorder Symptoms And Well-Being Among Hispanic World Trade Center Rescue And Recovery Workers, Dianne Ciro Feb 2018

Psychosocial Correlates Of Post-Traumatic Stress Disorder Symptoms And Well-Being Among Hispanic World Trade Center Rescue And Recovery Workers, Dianne Ciro

Dissertations, Theses, and Capstone Projects

Thousands of first responders are estimated to have endured extremely distressing experiences during their recovery efforts at the 9/11 World Trade Center (WTC) site. While the effects of 9/11 continue to be studied, few studies have examined how rescue and recovery workers have been coping since 9/11 and how their coping is associated with their psychological well-being. Moreover, we do not know how distinct coping patterns may be associated with post-traumatic growth, experiences of positive emotion, or quality of life among WTC responders.

This study compared coping differences among Hispanic, Non-Hispanic White, and Non-Hispanic Black first responders. In addition, it …


A Conceptualization Of The Body In Psychodynamic And Body-Based Psychotherapies: Areas Of Overlap And Possibilities For Integration, Aleksandra Rayska Sep 2017

A Conceptualization Of The Body In Psychodynamic And Body-Based Psychotherapies: Areas Of Overlap And Possibilities For Integration, Aleksandra Rayska

Dissertations, Theses, and Capstone Projects

The distinction between verbal and nonverbal psychotherapies is clearly visible in theory and clinical practice. Moreover, this duality of approaches promotes a split between the body and the mind, defining them as separate from each other. This dissertation helps bridge the divide between the literature in body-based therapies and verbally-based psychotherapy by (i) exploring the conceptual frame used to understand the body in psychodynamic therapy (ii) identifying the areas of overlap between psychodynamic theory and theories that underlie body-based psychotherapies, and (iii) proposing ways in which psychodynamic and body-based theories can inform one another. A clinical case was used to …


Cortical Thickness Abnormalities Within The Salience And Reward Networks In Older Depressed Adults With Apathy, Monique A. Pimontel Sep 2017

Cortical Thickness Abnormalities Within The Salience And Reward Networks In Older Depressed Adults With Apathy, Monique A. Pimontel

Dissertations, Theses, and Capstone Projects

Background and Significance: Apathy is a common comorbidity in late-life depression. Among older depressed adults, apathy is associated with a number of adverse outcomes, including increased disability, comorbid illness, and mortality. The etiological substrates of apathy in late-life depression nonetheless remain poorly understood, and little is known about its optimal treatment. To this end, the aim of the current study was to examine cortical abnormalities within the salience (SN) and reward networks (RN), two brain systems involved in the processing of incentive salience that may underlie the syndrome of apathy in older depressed adults.

Methods: We examined the association between …


Women’S Sexual Fantasies In Context: The Emotional Content Of Sexual Fantasies, Psychological And Interpersonal Distress, And Satisfaction In Romantic Relationships, Sarah Constantine Sep 2017

Women’S Sexual Fantasies In Context: The Emotional Content Of Sexual Fantasies, Psychological And Interpersonal Distress, And Satisfaction In Romantic Relationships, Sarah Constantine

Dissertations, Theses, and Capstone Projects

Background: Psychoanalytic thinkers propose that aspects of an individual’s sexual fantasies are related to her psychological and interpersonal functioning. The present study aims to elucidate the significance of sexual fantasies with respect to women’s emotional and interpersonal lives. The study evaluated a model, which hypothesized that internal representations of self and others (e.g. attachment security, maturity of object relations) along with psychological and interpersonal factors would predict both the emotional content (guilt, fear, affection) of written sexual fantasy narratives, and overall romantic satisfaction in heterosexual women. Methods: Five hundred and thirty four women completed self-report questionnaires online. Subsequently, the sexual …


Roles Of Gabab, Muscarinic And Nicotinic Receptor Signaling In The Acquisition And Expression Of Fructose And Fat-Conditioned Flavor Preferences And Acquisition Of Quinine-Conditioned Flavor Avoidances In Rats, Francis M. Rotella Sep 2017

Roles Of Gabab, Muscarinic And Nicotinic Receptor Signaling In The Acquisition And Expression Of Fructose And Fat-Conditioned Flavor Preferences And Acquisition Of Quinine-Conditioned Flavor Avoidances In Rats, Francis M. Rotella

Dissertations, Theses, and Capstone Projects

In addition to increased intake of sweet solutions by mammals, learning, particularly classically-conditioned “Pavlovian-like” learning, also plays an important role. An orosensory conditioned flavor preference (CFP) can be elicited by pairing one novel flavor (conditioned stimulus, CS+) with a fructose solution and a second novel flavor (CS-) with a saccharin solution. Rats will prefer the CS+ flavor in a subsequent 2-bottle choice test with both flavors mixed in saccharin. Previous pharmacological analyses revealed that systemic administration of dopamine (DA) D1 and D2 as well as NMDA, but not opioid, receptor antagonists eliminated the acquisition (learning) of fructose-CFP. Further, expression of …


Walking As Ontological Shifter: Thoughts In The Key Of Life, Bibi (Silvina) Calderaro Sep 2017

Walking As Ontological Shifter: Thoughts In The Key Of Life, Bibi (Silvina) Calderaro

Dissertations, Theses, and Capstone Projects

With walking as ontological shifter I pursue an alternative to the dominant modernist episteme that offers either/or onto-epistemologies of opposition and their reifying engagements. I propose this type of walking is an intentional turning towards a set of radical positions that, as integrative aesthetic and therapeutic practice, brings multiplicity and synchronicity to experience and being in an expanded sociality. This practice facilitates the conditions of possibility for recurring points of contact between the interiority perceived as ‘body’ and the exteriority perceived as ‘world.’ While making evident the self’s at once incoherence with it-self, it opens to a space beyond the …


Spatial-Relational Learning And Memory Deficits Associated With Nmdar Autoantibodies In Systemic Lupus Erythematosus, Brittany L. Bascetta Jun 2017

Spatial-Relational Learning And Memory Deficits Associated With Nmdar Autoantibodies In Systemic Lupus Erythematosus, Brittany L. Bascetta

Dissertations, Theses, and Capstone Projects

Individuals with Systemic Lupus Erythematosus (SLE) experience inflammation that may target any organ within the body, including the central and peripheral nervous systems. Additionally, these individuals often demonstrate psychological dysfunctions including emotional and cognitive deficits; however, research is inconsistent as to the nature and cause of these dysfunctions. While there are multiple factors that may increase risk for variability in cognitive function, such as population differences, socioeconomic status (SES), mood disorders (depression and anxiety), medication effects, and disease activity, these factors do not reliably predict the severity and extent of cognitive deficits. A growing body of animal research associates autoantibodies …


The Relationship Between Clinical Teaching Effectiveness And Emotional Intelligence In Clinical Nurse Faculty In Pre-Licensure Baccalaureate Programs In New York State, Caroline K. Mosca Feb 2017

The Relationship Between Clinical Teaching Effectiveness And Emotional Intelligence In Clinical Nurse Faculty In Pre-Licensure Baccalaureate Programs In New York State, Caroline K. Mosca

Dissertations, Theses, and Capstone Projects

It is important to evaluate the Clinical Teaching Effectiveness (CTE) of nurse faculty because clinical teaching is one of the most effective pedagogies in nursing education (Billings & Halstead, 2012). However, clinical faculty must be able to manage effectively the stressors of the clinical setting, where lessons can be unpredictable and the environment is often laden with intense emotion (Gerolamo & Roemer, 2011; Ondrejka, 2013; Roberts, Chrisman, & Flowers, 2013). Emotional Intelligence (EI) may facilitate CTE because higher EI has been associated with improved management of stress in both nursing and the general workplace (Goleman, 1995; Görgens-Ekermans & Brand, 2012; …


Expanding Intersectionality Praxis: Informing Culturally-Responsive Programming For Black And Latino Gay And Bisexual Young Men, Justin T. Brown Feb 2017

Expanding Intersectionality Praxis: Informing Culturally-Responsive Programming For Black And Latino Gay And Bisexual Young Men, Justin T. Brown

Dissertations, Theses, and Capstone Projects

Black/Latino gay/bisexual young men face a multitude of health disparities caused by various determinants of health. However, despite the awareness of the gaps, health intervention research rarely explores the impact of current health intervention strategies on Black/Latino gay/bisexual young men’s overall health and well-being. Traditional health interventions are deficit-based, health condition-specific, and often limited in their cultural-specificity. As health-related fields move toward holistic, evidence-based practices, new primary prevention approaches need to emerge. Using qualitative investigation strategies, this study included primary analysis of participatory workshop artifacts, and secondary analysis of survey and focus group data. This study identified critical factors necessary …


Warmth And Competence Traits: Perceptions Of Female And Male Nurse Stereotypes, Randolph E. Gross Feb 2017

Warmth And Competence Traits: Perceptions Of Female And Male Nurse Stereotypes, Randolph E. Gross

Dissertations, Theses, and Capstone Projects

A nursing shortage looms ahead; 1.03 million new nurses will be needed by 2022 to meet society's healthcare needs. A major barrier to recruitment of women and men are nurse stereotypes. The literature suggests four female and four male stereotypes exist; however, no quantitative research exists that explores perceptions of non-nursing undergraduate students. Approximately, 90% of college students do not consider nursing as a career option, and 72% have misconceptions of what nurses do in reality.

According to social cognitive theory's Stereotype Content Model (SCM), perceptions are viewed through a combination of two dimensions: warmth and competence. The author devised …


Medication Management In Pediatric Chronic Illness: Should Patient Anxiety Be Considered?, Claire J. Hoogendoorn Sep 2016

Medication Management In Pediatric Chronic Illness: Should Patient Anxiety Be Considered?, Claire J. Hoogendoorn

Dissertations, Theses, and Capstone Projects

Introduction: There is growing support that psychological symptoms can impact various aspects of disease, well-being, and medical treatment for those with a chronic illness like Crohn’s disease (CD). Yet, almost no studies have examined whether psychological symptoms can influence management or efficacy of patient medication regimens. The aims of this project were to examine whether anxiety predicted pediatric patients’ level of medication management, medication prescription changes, and corticosteroid prescription and duration.

Method: A total of 105 pediatric patients ages 8-18 (M=14.5, SD=2.3) completed a validated anxiety questionnaire during a GI office visit (baseline). Prescribed IBD …


Providing Care For Many In The Context Of Few Resources: Secondary Traumatic Stress, Burnout And Moral Distress Experienced By Healthcare Providers In Rural Uganda, Lauren Michelle Dewey Sep 2016

Providing Care For Many In The Context Of Few Resources: Secondary Traumatic Stress, Burnout And Moral Distress Experienced By Healthcare Providers In Rural Uganda, Lauren Michelle Dewey

Dissertations, Theses, and Capstone Projects

In the context of the global nursing shortage, and particularly in low-resource settings, nurses are at an increased risk for work-related stress problems like secondary traumatic stress (STS), burnout, and moral distress. These three work-related mental health consequences, sometimes associated with absenteeism and intent to leave the profession, could potentially contribute further to the shortage of nurses. This two-part study is a longitudinal examination of the work-related mental health consequences experienced by healthcare providers in rural Uganda. In Study 1, participants (n=208; 159 students and 49 experienced health workers) completed self-report, psychosocial measures at baseline and 134 of the students …


Observational Assessment Of Empathy In Parent-Child Verbal Exchanges And Their Influence On Child Behavior, Patty Carambot Sep 2016

Observational Assessment Of Empathy In Parent-Child Verbal Exchanges And Their Influence On Child Behavior, Patty Carambot

Dissertations, Theses, and Capstone Projects

Empathy, the ability to both experientially share in and understand others’ thoughts, behaviors, and feelings, is vital for human adaptation. Deficits in empathy development have implications across the lifespan for the development of prosocial behavior, social functioning, mental health disorders, and risk for antisocial behavior (e.g., Guajardo, Snyder, & Petersen, 2009; Moreno, Klute & Robinson, 2008). In light of these societal and individual burdens, it is imperative to foster and strengthen the development of this ability early in life to prevent or ameliorate such negative outcomes. This type of prevention can take a variety of forms, but parent and child …


The Relationship Between Lexical Performance And Regional Gray Matter Volumes: A Longitudinal Study Of Cognitively Healthy Elderly, Jungmoon Hyun Jun 2016

The Relationship Between Lexical Performance And Regional Gray Matter Volumes: A Longitudinal Study Of Cognitively Healthy Elderly, Jungmoon Hyun

Dissertations, Theses, and Capstone Projects

This study investigated the longitudinal relationship among aging, performance on lexical tasks, and regional gray matter volumes over 2-7 years. A total of 137 older participants who remained cognitively normal were administered four lexical tasks at each time point: the Boston Naming Test (BNT), Vocabulary Test, Semantic- and Phonemic-Fluency task. In addition, they underwent repeated magnetic resonance imaging (MRI) scanning acquired within two months of the lexical tasks. The average interval between time points was 2.36 years (range 1.50-7.64) and the average number of time points was 2.65 times (range 2-5).

Results indicated that age differentially affects lexical task performance …


Let Fall: Hysteria And The Psychoanalytic Act, Matthew W. Oyer Feb 2016

Let Fall: Hysteria And The Psychoanalytic Act, Matthew W. Oyer

Dissertations, Theses, and Capstone Projects

This text proposes to examine the contemporary crisis of psychoanalysis by taking seriously feminist critiques of the theory’s phallocentrism, but arguing that the phallus cannot be metaphorically or metonymically replaced by any substitutive term, as most revisionist theories of psychoanalysis have sought to do. Castration is the central psychoanalytic concept, though the theory always seeks to cover it over. In order to develop a psychoanalysis that can confront this castration that is always repressed and yet, in its persistent return, continuously disrupts the continuity of psychoanalytic theory, a detour is proposed, returning to the origins of psychoanalysis and taking hysteria …


Developmental Coordination Disorder: The Relationship Between Gait And Attention With Possible Implications For Early Identification And Intervention, Yocheved Bensinger-Brody Sep 2015

Developmental Coordination Disorder: The Relationship Between Gait And Attention With Possible Implications For Early Identification And Intervention, Yocheved Bensinger-Brody

Dissertations, Theses, and Capstone Projects

The aim of this research was to evaluate how increased levels of challenge to attentional capacity would affect the motor planning and coordination in the gait of children at risk of Developmental Coordination Disorder (DCD) across developmental ages. The study incorporated a dual task paradigm requiring both motor and attention performance, with the primary hypothesis that children who are at risk of DCD across different ages (3- to 8 yrs.-of-age) would demonstrate an alteration in their motor strategies if they were simultaneously engaging in an attention task. A secondary hypothesis of this study was that there is an underlying deficit …


The Neurophysiology Of Intersensory Selective Attention And Task Switching, Jeremy W. Murphy Feb 2015

The Neurophysiology Of Intersensory Selective Attention And Task Switching, Jeremy W. Murphy

Dissertations, Theses, and Capstone Projects

Our ability to selectively attend to certain aspects of the world and ignore others is fundamental to our day-to-day lives. The need for selective attention stems from capacity limitations inherent in our perceptual and cognitive processing architecture. Because not every elemental piece of our environment can be fully processed in parallel, the nervous system must prioritize processing. This prioritization is generally referred to as selective attention. Meanwhile, we are faced with a world that is constantly in flux, such that we have to frequently shift our attention from one piece of the environment to another and from one task to …


When Less Can Be More: Dual Task Effects In Stuttering And Fluent Adults, Naomi Nechama Eichorn Oct 2014

When Less Can Be More: Dual Task Effects In Stuttering And Fluent Adults, Naomi Nechama Eichorn

Dissertations, Theses, and Capstone Projects

The present study tested the counterintuitive hypothesis that engaging cognitive resources in a secondary task while speaking could benefit aspects of speech production. Effects of dual task conditions on speech fluency, rate, and error patterns were examined in stuttering and fluent speakers based on specific predictions derived from three related theoretical frameworks. Twenty fluent adults and 19 adults with confirmed diagnoses of stuttering participated in the study. All participants completed two baseline tasks: (1) a continuous speaking task in which spontaneous speech was produced in response to given prompts; and (2) a working memory (WM) task involving manipulations of WM …


Characterization Of Somatosensory Processing In Relation To Schizotypal Traits In A Sample Of Nonclinical Young Adults, Maureen Patricia Daly Oct 2014

Characterization Of Somatosensory Processing In Relation To Schizotypal Traits In A Sample Of Nonclinical Young Adults, Maureen Patricia Daly

Dissertations, Theses, and Capstone Projects

A core feature of schizophrenia spectrum disorders (SSDs) is a basic sensory (e.g., visual, auditory) processing disruption, yet few studies have examined somatosensation. The current dissertation project examined somatosensory processes among individuals at varying degrees of psychometric risk for psychosis using tactile texture and spatial discrimination and letter recognition tasks. Differential patterns of associations of somatosensory abilities with schizotypal trait dimensions (positive, negative, disorganized), independent of anxiety and depressive symptoms, and the relative contributions of bottom-up (peripheral and morphologic features) versus top-down (error types) processing were examined. It was hypothesized that: 1) performance on somatosensory tasks would account for significant …


A Meta-Analysis Of The Prediction Of Violence Among Adults With Mental Disorders, Hing Po Lam Oct 2014

A Meta-Analysis Of The Prediction Of Violence Among Adults With Mental Disorders, Hing Po Lam

Dissertations, Theses, and Capstone Projects

The study of the risk for violence among persons with mental disorders has received substantial scientific attention over the past few decades; however, many uncertainties and controversies remain due to the wide disparities in the reported results. Using the state-of-the-art perspective of public health, a meta-analysis was conducted to clarify the ambiguities by synthesizing quantitative findings from 85 research reports (completed between January 1970 and May 2010) on violence risk assessment among mentally disordered adults. Results of this meta-analytic study revealed that the estimates of the prevalence of violence among the psychiatric population varied considerably from 1.1% to 78.4% with …
