Genomic Copy Number Variation In Mus Musculus., M Elizabeth O Locke, Maja Milojevic, Susan T Eitutis, Nisha Patel, Andrea E Wishart, Mark Daley, Kathleen A. Hill

Brain and Mind Institute Researchers' Publications

BACKGROUND: Copy number variation is an important dimension of genetic diversity and has implications in development and disease. As an important model organism, the mouse is a prime candidate for copy number variant (CNV) characterization, but this has yet to be completed for a large sample size. Here we report CNV analysis of publicly available, high-density microarray data files for 351 mouse tail samples, including 290 mice that had not been characterized for CNVs previously.

RESULTS: We found 9634 putative autosomal CNVs across the samples affecting 6.87% of the mouse reference genome. We find significant differences in the degree of …

Impact Of A Teacher Training Program To Increase Cognitively Stimulating Talk: Pretest And Immediate Post-Test Results, Laura E. Fisher

Masters Theses & Specialist Projects

The literacy skills that students develop in preschool are an imperative aspect of school readiness and later academic success. Research has established that some students begin their educational experience at a disadvantage due to the low socioeconomic status (SES) of their family and, as a result, low levels of conversation between parents and children, restricted access to books, and low values placed on literacy. Past research supports that shared book reading is one of the most beneficial activities in which teachers can partake in order to optimize their students’ language development. The Head Start program is intended to alleviate the …

Cultural Context's Influence On The Relationships Between Leadership Personality And Subordinate Perceptions, Victoria J. Smoak

Doctoral Dissertations

Fascination with leadership and the pursuit of its understanding have been common across disciplines throughout history (Bass & Stogdill, 1990). Studying leadership in an organization provides value in understanding its relation to outcomes such as employee attitudes (Podsakoff, MacKenzie, & Bommer, 1996), individual performance (Tierney, Farmer, & Graen, 1999) and organizational performance (Day & Lord, 1988; Sully de Luque, Washburn, Waldman, & House, 2008). Leadership is suggested to be the underlying human factor key to organizational effectiveness (Hogan & Kaiser, 2005). In spite of the vast body of literature, much remains to be understood, especially understanding context (McCall & Hollenbeck, …

Embracing Multiple Definitions Of Learning, Andrew B. Barron, Eileen A. Hebets, Thomas A. Cleland, Courtney L. Fitzpatrick, Mark E. Hauber, Jeffrey R. Stevens

Eileen Hebets Publications

Definitions of learning vary widely across disciplines, driven largely by different approaches used to assess its occurrence. These definitions can be better reconciled with each other if each is recognized as coherent with a common conceptualization of learning, while appreciating the practical utility of different learning definitions in different contexts.

Learning is a major focus of research in psychology, neuro- science, behavioral ecology, evolutionary theory, and computer science, as well as in many other disciplines. Despite its conceptual prevalence, definitions of learning differ enormously both within and between these disciplines, and new definitions continue to be proposed [1]. Ongoing disputes …

It used in-depth narrative interviews to elicit my responses to lived experiences from growing up in Mexico to my current teaching position. Thematic …

Toward A Relational Humanism, Kenneth J. Gergen

Psychology Faculty Works

Humanist conceptions of the person evolve across history. Whereas humanism has served a pivotal role in the caregiving professions, its individualist emphasis now stands as an impediment to its future. Proposed is a relational reconceptualization of the person, placing relational as opposed to individual well-being at the forefront of humanists' concerns.

Dualism And Doctrine, Dov Fox, Alex Stein

Indiana Law Journal

What kinds of harm among those that tortfeasors inflict are worthy of compensation? Which forms of self-incriminating evidence are privileged against government compulsion? What sorts of facts constitute a criminal defendant’s intent? Existing doctrine pins the answer to all of these questions on whether the injury, facts, or evidence at stake are “mental” or “physical.” The assumption that operations of the mind are meaningfully distinct from those of the body animates fundamental rules in our law.

A tort victim cannot recover for mental harm on its own because the law presumes that he is able to unfeel any suffering arising …

Behavioral And Pharmacological Investigation Of Anxiety And Maternal Responsiveness Of Postpartum Female Rats In A Pup Elevated Plus Maze, Yu Yang, Jingxue Qin, Weihai Chen, Hong Chen, Ming Li

Department of Psychology: Faculty Publications

The present study investigated the validity of a novel pup-based repeated elevated plus maze task to detect reduced anxiety and increased maternal responsiveness in postpartum female rats and explored the roles of dopamine D2, serotonin transporter and GABA/benzodiazepine receptors in the mediation of these processes. Sprague–Dawley postpartum or nulliparous female rats were tested 4 times every other day on postpartum days 4, 6 and 8 in an elevated plus maze with 4 pups or 4 pup-size erasers placed on each end of the two open arms. When tested with erasers, untreated postpartum mother rats entered the open arms proportionally more …

Ptsd Symptom Severity And Neurocognitive Performance As A Function Of Combined Tms And Imaginal Exposure In Oif/Oef Combat Veterans With Treatment Resistant Ptsd, Katharine Seagly

Psychology Theses & Dissertations

Posttraumatic Stress Disorder (PTSD) is a commonly occurring mental health diagnosis, and is particularly prevalent in combat veterans. Although there has been some success treating PTSD with various forms of therapy, many cases remain refractory to the current standard of care. This pilot study combines transcranial magnetic stimulation (TMS) to the right dorsolateral prefrontal cortex (DLPFC) and the supplementary motor area (SMA) with a standardized exposure protocol for the treatment of chronic, treatment-resistant PTSD. The aims are to (1) determine if the treatment is safe and well tolerated, (2) determine if PTSD and concomitant depression and anxiety symptoms improve, and …

Examining The Measurement Invariance Of The Minnesota Multiphasic Personality Inventory-2-Restructured Form Internalizing Specific Problem Scales In African- American And Caucasian Men, Megan Anne Brokenbourgh

Psychology Theses & Dissertations

Test bias has long been an area of investigation in the personality assessment literature, including the MMPI-2-RF. Research on previous versions of the MMPI and MMPI-2-RF has pointed to mixed results. The current study aims to examine test bias on the MMPI-2-RF’s nine Internalizing Specific Problem Scales by examining measurement invariance using MIMIC modeling and investigating differential item functioning (DIF). After removal of invalid protocols, the first sample consisted of 2,980 protocols from various settings requested from Pearson (255 African American and 2,755 Caucasian protocols). The second sample consisted of 1,379 valid protocols from psychiatric inpatient settings (1,245 Caucasian and …

Comparative Analysis Of Meissner's Corpuscles In The Fingertips Of Primates, A. Verendeev, C. Thomas, S. C. Mcfarlin, William D. Hopkins, Kimberley A. Phillips, Chet C. Sherwood

Psychology Faculty Research

Meissner's corpuscles (MCs) are tactile mechanoreceptors found in the glabrous skin of primates, including fingertips. These receptors are characterized by sensitivity to light touch, and therefore might be associated with the evolution of manipulative abilities of the hands in primates. We examined MCs in different primate species, including common marmoset (Callithrix jacchus, n = 5), baboon (Papio anubis, n = 2), rhesus macaque (Macaca mulatta, n = 3), chimpanzee (Pan troglodytes, n = 3), bonobo (Pan paniscus, n = 1) and human (Homo sapiens, n = 8). Fingertips …

Donepezil’S Effect On Cardiac Function In Patients With Alzheimer’S Disease Through An In Vivo, Non Invasive Measure Of Cardiac Autonomic Function, Lewis P. Hackett

Psychology Theses & Dissertations

The aim of the current study was to explore the effects of the medication Donepezil (Aricept®) on cardiac autonomic function for individuals diagnosed with mild to moderate (probable) Alzheimer’s disease (AD). Using age (± 3 years) and gender matched controls, differences in heart rate variability (HRV) among individuals with Alzheimer’s disease were compared to healthy controls over a period of six months (session 1 [baseline], session 2 [3 months], and session 3 [6 months]) in both supine and standing positions. HRV was obtained through frequency-domain (Low Frequency Power, High Frequency Power, RMSSD, LF/HF Ratio) and time-domain (six minutes) measures using …

Effects Of Varying Degrees Of Fixed And Random Responding On The Validity Of Score Interpretation For The Sp And Psy-5 Scales Of The Mmpi-2-Rf, Joseph Brooks Minifie

Psychology Theses & Dissertations

The Minnesota Multiphasic Personality Inventory – 2 Restructured Form (MMPI-2- RF; Tellegen & Ben-Porath, 2008/2011) is a widely used self-report measure of psychopathology and personality. However, the self-report format of the MMPI-2-RF suggests that interpretation of its scales and the clinical recommendations that follow are vulnerable to invalid response styles. This dissertation builds upon previous research (Handel, Ben-Porath, Tellegen, & Archer, 2010) to examine the effect of random and fixed responding, as measured by the VRIN-r and TRIN-r Scales, on the 28 SP and PSY-5 Scales. A computer simulation procedure was used to insert increasing degrees of inconsistent responding into …

Application Of Item Response Theory To Measures Of Verbal Learning, Indrani K. Thiruselvam

Dissertations (1934 -)

This study utilized item response theory (IRT) methods to investigate if item parameters of select trials in the California Verbal Learning Test-Second Edition (CVLT-II; Delis, Kramer, Kaplan, & Ober, 2000) and the Logical Memory subtests of the Wechsler Memory Scales – Fourth Edition (WMS-IV; Wechsler, 2009) vary as a function of the serial position effect. In addition, this study compared the effectiveness of CVLT-II and LM in quantifying verbal memory functioning, and determined if a weighted scoring approach improves the quantification of verbal memory. Archival data from 755 individuals (516 college students, 239 patients at a neuropsychology clinic) were utilized …

Interactions Between Maternal Prenatal Obesity And Physiological Stress: Predictors Of Offspring Adult Obesity, Jennifer L. Hambleton, Jared Vineyard, Nicki L. Aubuchon-Endsley (Mentor)

Idaho Conference on Undergraduate Research

Over half of US women of childbearing age are overweight or obese. This is significant because excessive gestational maternal weight may program offspring for greater risk of lifetime obesity. Preliminary research suggests this effect may be moderated by fetal exposure to stress hormones, known to be dysregulated in obese individuals. However, long-term longitudinal research of these constructs is needed.

Therefore, this study used archival data from the NEFS/CPP Studies to examine interactions between maternal pre-pregnancy BMI/gestational weight gain and fetal cortisol exposure as predictors of offspring growth trajectories from birth-7 years and adult BMI via growth curve modeling and ANOVAs. …

Neonatal Isolation Stress Inhibits Pre-Weaning Weight Gain And Mild-Stressor Induced Locomotor Activity In Early Adolescent Male And Female Rats, Peter Villavecchia, Mindy Miserendino

Psychology Faculty Publications

The present study looked at the effects of neonatal isolation, an early life stress experience, in male and female early adolescent rats, an age which is underrepresented in the early stress literature. Four stress-sensitive indices were assessed: weight gain during the pre-weaning period, open field activity, and locomotor activity in response to two mild stressors: exposure to a novel environment, and a single IP saline injection. Rats in the neonatal isolation condition were removed from dam and littermates on postnatal days 2-9 in accord with the procedure used by Kehoe et al. (1995); behavioral testing occurred on PN25-PN30 during …

Impaired Synaptic Development In A Maternal Immune Activation Mouse Model Of Neurodevelopmental Disorders, Pierluca Coiro, Ragunathan Padmashri, Anand Suresh, Elizabeth Spartz, Gurudutt Pendyala, Shinnyi Chou, Yoosun Jung, Brittney Meays, Shreya Roy, Nagsen Gautam, Yazen Alnouti, Ming Li, Anna Dunaevsky

Department of Psychology: Faculty Publications

Both genetic and environmental factors are thought to contribute to neurodevelopmental and neuropsychiatric disorders with maternal immune activation (MIA) being a risk factor for both autism spectrum disorders and schizophrenia. Although MIA mouse offspring exhibit behavioral impairments, the synaptic alterations in vivo that mediate these behaviors are not known. Here we employed in vivo multiphoton imaging to determine that in the cortex of young MIA offspring there is a reduction in number and turnover rates of dendritic spines, sites of majority of excitatory synaptic inputs. Significantly, spine impairments persisted into adulthood and correlated with increased repetitive behavior, an ASD relevant …

I Judge, Therefore I React: An Experimental Investigation Of Acceptance, Jennifer Ann Shaver

Graduate Theses and Dissertations

The present study was designed to provide empirical tests of some of the mechanisms thought to operate in mindfulness-based treatments. Specifically, I tested the hypothesis that appraising distress judgmentally (as a needless and useless indication of personal weakness) would be associated with experiencing meta-distress (e.g., feeling ashamed about being distressed), which would, in turn, be associated with increased experiential avoidance (i.e., suppression or distraction from the distress) and shorter distress tolerance. In addition, I examined the hypothesis that compassionately appraising distress (as normal, understandable, and potentially a source of growth) would be associated with spending more time curiously exploring that …

Cortisol Profiles As Bio-Markers Of Extreme Temperaments, Claudia Rasmuseen, Dr. James Dee Higley

Journal of Undergraduate Research

Temperament is defined as a variation between individuals’ affective-motivational reactivity and self-regulation (Rothbart & Bates, 1998; Rothbart & Derryberry, 1981; Rettew &McKee, 2005). Temperament can be measured as early as birth and has been found to remain relatively stable across the lifespan (Goldsmith, 1987; Lansade, Bouissou & Erhard, 2008;Chronis-Tuscano, et.al, 2009). Although most temperaments used to be grouped into reactivity and self-regulation, new temperament taxonomies have been found to belong to two higher order dimensions: degree of sensitivity to signals of punishment and a propensity to experience negative emotions (Rettew & McKee, 2005). The variety in taxonomies extends to non-human …

Effects Of Chronic Ethanol On Gaba(A) Receptors In The Vta, Ashley Nelson, Dr. Scot Steffensen

Journal of Undergraduate Research

The Centers for Disease Control and Prevention attributes approximately 80,000 deaths annually to excessive alcohol use (CDC), and alcohol consumption is the third leading cause of preventable deaths in the United States (Mokdad et al., 2004). These statistics do not even describe the detrimental effects alcohol addiction has on personal lives and families. The accepted model for addiction in the brain is a change in the normal regulation of the neurotransmitter dopamine (DA) in the mesolimbic pathway. Studying this pathway is important in developing treatments for addiction, which has implications to improve the lives of many suffering people. The primary …

Role Of Ros (Reactive Oxygen Species) On Cocaine-Induced Da Release In The Nac, Jacqueline Solomon, Dr. Scott Steffensen

Journal of Undergraduate Research

Cocaine as a stimulant drug causes Dopamine (DA), a neurotransmitter, to be released in the Accumbens Nucleus (NAc). It accomplishes this by its well-known actions on the DA transporter (DAT). When the DAT is blocked, more DA stays in the synaptic cleft, leading to rewarding and pleasurable sensations. While in the synaptic cleft, DA undergoes excessive oxidation, giving rise to oxidative stress (OS) which causes neural damage. The OS has been shown in damaging the pleasure pathway and makes it so that addictive pathways are formed. In this research study we saw that Reactive Oxygen Species (ROS) Scavengers can eliminate …

An Examination Of The Relationship Between Childhood Abuse, Anger And Violent Behavior Among A Sample Of Sex Offenders, Stephanie R. Ramirez, Elizabeth L. Jeglic, Cynthia Calkins

Publications and Research

Background: Increasing attention has focused on the emotional dysregulation that can result from adverse childhood experiences among those who commit sexually violent crimes. While studies confirm a relationship between child maltreatment and anger the research is limited and it is unclear how anger and child maltreatment effect the use of violence during the commission of the sex crime.

Methods: This study examined the relationship between childhood maltreatment, anger and violent behavior by reviewing the records of 571 adult male offenders convicted of sexual assault or child molestation. The aims of the present study were to 1) examine differences in anger …

The significance of this current study was to show the importance of Black History being added to the curriculum for elementary students of all ethnicities, but especially with the African-American children. During this study the students were given a pre- and post-test on the Civil Rights Movement for the month of February. The study consisted of 40 students from an upper elementary school located in southern New Jersey. Of the participants 26 were female and 14 were male; there are 4 special needs students and 2 in a reading program called Read 180. All were in the 6th grade with …

Does Our Fear Of Death Stem From Threatened Belongingness?, Stan Treger

College of Science and Health Theses and Dissertations

In this dissertation, I examine the relative contribution to worldview defense (i.e., upholding one’s cultural worldviews) provided by the thoughts of one’s death and perceptions of curbed close relationships.

The need to belong, to form meaningful and strong ties with others, is what many social psychologists believe to be one of the most fundamental and strongest motivations that humans possess (Baumeister, 2012; Baumeister & Leary, 1995; Kenrick, Griskevicius, Neuberg, & Schaller, 2010; Tomasello, 2014). The human brain is “hard-wired” to be around others (Beckes & Coan, 2011). In fact, large social group sizes of humans’ evolutionary past may have contributed …

Effects Of Early-Adolescent, Mid-Adolescent, Or Adult Stress On Morphine Conditioned Place Preference, Chloe Shields

Senior Theses

In light of previous work demonstrating that stress can increase subjective drug reward in adult rats, the present study investigated the influence of stress on morphine conditioned place preference (CPP) in early-adolescent, mid-adolescent, and adult male Sprague-Dawley rats. Subjects in each age group were assigned to either a no stress condition or a stress condition in which they were exposed to an unpredictable eight-day schedule of elevated platform and synthetic fox odor stressors. Place conditioning then evaluated subjective morphine reward in all animals. Using a biased procedure, subjects were assigned to receive morphine on the initially non-preferred side of the …

Transformational Leadership, Diversity, And Creativity At Work: A Moderated Mediation Model, Aisha Smith Taylor

Dissertations and Theses

Organizational leaders often seek to hire and retain innovative employees as a source of competitive advantage. Both transformational leadership and effectively managed workplace diversity have been theorized and shown to lead to increased employee creative performance at work; however, a full model of the relationships between leadership and the multi-dimensional construct of workplace diversity has not yet been tested. Using a sample of 371 employees in three Chinese high-technology firms matched with 64 supervisors collected at three time points, this study theorized and tested a moderated mediation path model in which transformational leadership and diversity climate were predicted to significantly …

Reversal Of Age-Associated Cognitive Deficits Is Accompanied By Increased Plasticity-Related Gene Expression After Chronic Antidepressant Administration In Middle-Aged Mice, Yan Li, Aicha Abdourahman, Joseph A. Tamm, Alan Pehrson, Connie Sánchez, Maria Gulinello

Department of Psychology Faculty Scholarship and Creative Works

Cognitive decline occurs during healthy aging, even in middle-aged subjects, via mechanisms that could include reduced stem cell proliferation, changed growth factor expression and/or reduced expression of synaptic plasticity genes. Although antidepressants alter these mechanisms in young rodents, their effects in older animals are unclear. In middle-aged mice, we examined the effects of a selective serotonin reuptake inhibitor (fluoxetine) and a multimodal antidepressant (vortioxetine) on cognitive and affective behaviors, brain stem cell proliferation, growth factor and gene expression. Twelve-month-old female C57BL/6 mice exhibited impaired visuospatial memory in the novel object placement (location) task associated with reduced expression of several plasticity-related …

Object Permanence In The Dwarf Goat (Capra Aegagrus Hircus): Perseveration Errors And The Tracking Of Complex Movements Of Hidden Objects, Christian Nawroth, Eberhard Von Borell, Jan Langbein

Memory Collection

Object permanence is the notion that objects continue to exist even when they are out of an observer’s sight. In mammals, the highest stage of object permanence (Stage 6) has been observed only in primates, whereas other species have shown difficulty in following once-hidden objects, particularly when complex movements are involved. We conducted four experiments to examine the ability of dwarf goats to mentally represent once-hidden objects. In Experiment 1, we investigated whether dwarf goats are prone to commit the A-not-B or perseveration error which is commonly used as a measure for self-control. Subjects here continue to search for an …

Navajo Nation Brain Drain: An Exploration Of Returning College Graduates' Perspectives, Quintina Ava Adolpho

Theses and Dissertations

American Indian tribes face the phenomenon known across the world as the brain drain. They invest millions of dollars in educating their members, only to have little return on their investments. Many nation members leave reservations to get postsecondary education but never return, contributing to the brain drain. Those who get education off the reservation and choose to return are the exceptions to this rule. Although there is an abundance of literature regarding the brain drain across the world, there has been little research done with American Indians. In order to begin to understand the brain drain phenomenon this study …
