Neurologists Look At Causes Of Baffling Brain Condition, Maggie Freleng

Capstones

It can be hard getting help for someone with mental illness, but almost impossible when that person doesn't think they are sick. At at least half of people with schizophrenia, for example, insist that the voices they hear are real. People who do not know they are ill often refuse therapy and medication -- and their symptoms can spiral out of control. Doctors call this lack of awareness anosognosia. Neurologists are trying to discover what causes this baffling condition--and how to treat it.

The Happy Older Latinos Are Active (Hola) Health Promotion And Prevention Study: Study Protocol For A Pilot Randomized Controlled Trial, Daniel E. Jimenez, Charles F. Reynolds, Margarita Alegría, Philip Harvey, Stephen Bartels

Dartmouth Scholarship

Results of previous studies attest to the greater illness burden of common mental disorders (anxiety and depression) in older Latinos and the need for developing preventive interventions that are effective, acceptable, and scalable. Happy Older Latinos are Active (HOLA) is a newly developed intervention that uses a community health worker (CHW) to lead a health promotion program in order to prevent common mental disorders among at-risk older Latinos. This pilot study tests the feasibility and acceptability of delivering HOLA to older, at-risk Latinos.

Methods/Design: HOLA is a multi-component, health promotion intervention funded by the National Institute of Mental Health (NIMH). …

Nucleus Accumbens Deep Brain Stimulation In A Rat Model Of Binge Eating, W. T. Doucette, J. Y. Khokhar, A. I. Green

Dartmouth Scholarship

Binge eating (BE) is a difficult-to-treat behavior with high relapse rates, thus complicating several disorders including obesity. In this study, we tested the effects of high-frequency deep brain stimulation (DBS) in a rodent model of BE. We hypothesized that BE rats receiving high-frequency DBS in the nucleus accumbens (NAc) core would have reduced binge sizes compared with sham stimulation in both a 'chronic BE' model as well as in a 'relapse to chronic BE' model. Male Sprague-Dawley rats (N=18) were implanted with stimulating electrodes in bilateral NAc core, and they received either active stimulation (N=12) or sham stimulation (N=6) for …

Smoking And Exercise: Mechanisms And Effects During Simulated And Genuine Quit Attempts, Stefanie De Jesus

Electronic Thesis and Dissertation Repository

Cigarette smoking is a leading agent for premature morbidity and mortality among the global community. Most individuals surrender to tobacco use disorder due to the inability to cope with cravings and withdrawal symptoms. Exercise appears to provide acute relief. Currently, it is unclear how exercise attenuates these reductions. Furthermore, the available evidence has focused on acute outcomes besides smoking behaviour and is limited to simulated quit attempts. Three experimental studies were designed to address these outstanding issues. Not surprisingly, a bout of moderate intensity exercise was found in study 1 (chapter 2) to reduce cravings associated with a temporary period …

Effects Of Repeated Quetiapine Treatment On Conditioned Avoidance Responding In Rats, Jun Gao, Min Feng, Natashia Swalve, Collin Davis, Nan Sui, Ming Li

Department of Psychology: Faculty Publications

The present study characterized the behavioral mechanisms of avoidance–disruptive effect of quetiapine in the conditioned avoidance response test under two behavioral testing (2 warning signals vs. 1 warning signal) and two drug administration conditions (subcutaneous vs. intravenous). In Experiments 1 and 2, well-trained adult male Sprague-Dawley rats were tested under the subcutaneous (s.c.) quetiapine treatment (5.0, 15.0, 25.0, 50.0 mg/kg) for 7 days in a novel procedure consisting of two conditioned stimuli (CS) (white noise serving as CS1 and pure tone as CS2). Only the highest dose (50.0 mg/kg) produced a persistent suppression of the avoidance response without impairing the …

The Visual Priming Of Motion-Defined 3d Objects, Xiong Jiang, Yang Jiang, Raja Parasuraman

Behavioral Science Faculty Publications

The perception of a stimulus can be influenced by previous perceptual experience, a phenomenon known as perceptual priming. However, there has been limited investigation on perceptual priming of shape perception of three-dimensional object structures defined by moving dots. Here we examined the perceptual priming of a 3D object shape defined purely by motion-in-depth cues (i.e., Shape-From-Motion, SFM) using a classic prime-target paradigm. The results from the first two experiments revealed a significant increase in accuracy when a "cloudy" SFM stimulus (whose object structure was difficult to recognize due to the presence of strong noise) was preceded by an unambiguous SFM …

Characterizing The Performance And Behaviors Of Runners Using Twitter, Qian He, Emmanuel Agu, Diane Strong, Bengisu Tulu, Peder Pedersen

Emmanuel O. Agu

Running is a popular physical activity that improves physical and mental wellbeing. Unfortunately, up-to- date information about runners’ performance and psychological wellbeing is limited. Many questions remain unanswered, such as how far and how fast runners typically run, their preferred running times and frequencies, how long new runners persist before dropping out, and what factors cause runners to quit. Without hard data, establishing patterns of runner behavior and mitigating the challenges they face are difficult. Collecting data manually from large numbers of runners for research studies is costly and time consuming. Emerging Social Networking Services (SNS) and fitness tracking devices …

Evening Snacking In Relation To Self-Reported Declines In Sleep Quality During Pregnancy: Preliminary Results From The Decision-Making, Eating, And Weight Gain During Pregnancy (Dew) Study, Wendy Mccallum, Bradley M. Appelhans, Tiffany A. Moore Simas, Rui Sherry Xiao, Shums Alikhan, Isabelle C. Pierre-Louis, Barbara C. Olendzki, Sherry L. Pagoto, Molly E. Waring

Tiffany A. Moore Simas

Background: Poor sleep in non-pregnant adults has been associated with increased evening snacking, which may contribute to weight gain. Sleep disturbances are common during pregnancy.

Objective: To examine the association between changes in sleep quality from pre-pregnancy and evening snacking.

Methods: In an ongoing prospective cohort study, pregnant women were recruited from UMMHC obstetric practices and the community. Participants are 18+ years, with singleton gestation <36 >weeks, pre-pregnancy BMI 18.5-40 kg/m2, English-speaking, and with plans to deliver at UMMHC. Participants were asked “compared to the three months before you became pregnant, how is your sleep quality now?”; we combined responses of …

Exploring Acceptance Of Using An Online Platform To Teach Parents Of Children With Autism Methods In Applied Behavior Analysis (Aba), Marwah S. Zagzoug

Seton Hall University Dissertations and Theses (ETDs)

Background and Purpose of the Study: A diagnosis of autism can lead to lifelong struggles for parents and children. These families face profound difficulties in coping with stress while seeking out early interventions and managing imperative service needs. Parents are increasingly turning to the internet for information, advice, and even formal training. Breakthroughs in technology have made the internet more accessible and more sophisticated. The involvement of parents in applying intervention strategies to help their autistic children has long been advocated as a useful approach. Enabling parents as interventionists provides renewed confidence and reduced stress for parents as well as …

Criminal Law And Common Sense: An Essay On The Perils And Promise Of Neuroscience, Stephen J. Morse

All Faculty Scholarship

This article is based on the author’s Barrock Lecture in Criminal Law presented at the Marquette University Law School. The central thesis is that the folk psychology that underpins criminal responsibility is correct and that our commonsense understanding of agency and responsibility and the legitimacy of criminal justice generally are not imperiled by contemporary discoveries in the various sciences, including neuroscience and genetics. These sciences will not revolutionize criminal law, at least not anytime soon, and at most they may make modest contributions to legal doctrine, practice, and policy. Until there are conceptual or scientific breakthroughs, this is my story …

The Transformative And Healing Powers Of Compassion, Forgiveness, And Wonder, Anna C. Eriksson-Marty

Senior Theses

Since time immemorial, humankind has struggled to coexist peacefully together. As human beings, we strive on our relationships with each other and, yet, with actions of hatred and prejudice, we seem to consistently destroy those very relationships we value so deeply. Our current society is plagued by fear, which seems to run more rampant now – more than ever – with assistance of our rapidly evolving communication technology. The question must be asked, “How can we end this madness and heal ourselves into a kinder and more fulfilling future?” By providing up-to-date scientific research on the human emotions of compassion, …

The Effects Of Alpha Stimulation On Induced Anxiety, Nolan Thomas Hill

Electronic Theses and Dissertations

Anxiety is defined as an emotional and physical reaction that prepares us to confront a feared stimulus. Among the many measureable changes induced by anxiety are changes in facial electromyography (EMG), heart rate (HR), and sweat gland activity (EDG). At a pathological level anxiety interferes with cognitive processes. Currently, when anxiety crosses into the pathological level, it is treated with a variety of therapies that share in their use of periods of exposure to anxiety-inducing stimuli. Several devices have been developed to alter brain activity by transcranial electrical stimulation (TCES). One such device, Alpha-Stim^®, has been shown to …

Social Motivation Is Associated With Elevated Salivary Cortisol In Boys With An Asd, Vicki Bitsika, Christopher Sharpley, Linda Agnew, Nicholas Andronicos

Vicki Bitsika

Because social communication difficulties and stress are common in children with an ASD, and because it has been hypothesised that the two are related, the association between these two variables was investigated in a sample of 90 boys with an ASD and who were aged between 6 years and 12 years of age. The Social Responsiveness Scale (SRS) was completed by the parents of these boys about their sons, plus salivary cortisol samples were collected from the boys. Results indicated that only one aspect of the boys' SRS was significantly correlated with cortisol—Social Motivation (SM). Factor analyses revealed two discrete …

Age-Related Differences In The Association Between Stereotypic Behaviour And Salivary Cortisol In Young Males With An Autism Spectrum Disorder, Vicki Bitsika, Christopher Sharpley, Linda Agnew, Nicholas Andronicos

Vicki Bitsika

To identify if age influenced the relationship between one of the central symptoms of Autism Spectrum Disorder (ASD) and physiological stress, the association between stereotypic behaviour (SB) and stress-related cortisol concentrations was examined in a sample of 150 young males with an ASD. Parent-rated SB was significantly correlated with cortisol concentrations for boys aged 6 years to 12 years but not for adolescents aged 13 years to 18 years. This age-related difference in this association was not a function of cortisol concentrations but was related to differences in SB across these two age groups. IQ did not have a significant …

Investigating The Influences Of Language Delay And/Or Familial Risk For Dyslexia On Brain Structure In 5-Year-Olds, Nora Maria Raschle, Bryce Larkin Chessell Becker, Sara Smith, Lynn Valérie Fehlbaum, Yingying Wang, Nadine Gaab

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Early language delay has often been associated with atypical language/literacy development. Neuroimaging studies further indicate functional disruptions during language and print processing in school-age children with a retrospective report of early language delay. Behavioral data of 114 5-year-olds with a retrospective report of early language delay in infancy (N = 34) and those without (N = 80) and with a familial risk for dyslexia and those without are presented. Behaviorally, children with a retrospective report of early language delay exhibited reduced performance in language/reading-related measures. A voxel-based morphometry analysis in a subset (N = 46) demonstrated an association between reduced …

Assessing The Synergistic Effect Of Caffeine And Sugar On Cognitive Performance In Undergraduate Students, Sandra P. Urquiza, Michelle Vieyra

Journal of the South Carolina Academy of Science

Working independently, both caffeine and sugar provide benefits to attention and memory. However, there is sparse literature on the synergistic effects on improved cognitive performance between caffeine and sugar when taken together. This study explored the dynamics between caffeine and sugar when consumed under ordinary conditions – as a cup of coffee. Twenty-four undergraduate students (15 women and 9 men) were asked to complete a baseline cognitive test, and one of the three variables was given at random in the form of a cup of coffee: decaffeinated with sugar, caffeinated with no sugar, and caffeinated with sugar. The remaining two …

How We Saved Ourselves: A Look At The Positive Coping Strategies The Orphans Of The 1994 Genocide Against Tutsis Implemented During Bereavement, Gregory Barber

Independent Study Project (ISP) Collection

Recent estimates report that there are approximately 145 million children worldwide who have lost at least one parent as a result of various causes (Development, 2008). Parental death is one of the most traumatic events that can occur in childhood (Haine, 2006). Literature has also indicated that parental death places children at risk for many negative outcomes, including mental health problems, grief, lower academic success, self-esteem, and greater external locus of control (Lutzke, 1997). Between April and July 1994, 800,000 to 1,000,000 Rwandans died in the 1994 genocide against Tutsis. Because of the 1994 genocide against Tutsis, nearly 75,000 children …

Proyecto Mama: A Lifestyle Intervention In Overweight And Obese Hispanic Women: A Randomised Controlled Trial--Study Protocol, Lisa Chasan-Taber, Bess H. Marcus, Milagros C. Rosal, Katherine L. Tucker, Sheri J. Hartman, Penelope S. Pekow, Edward J. Stanek Iii, Barry Braun, Caren G. Solomon, Joanne Manson, Sarah L. Goff, Glenn Markenson

Sarah L. Goff MD

BACKGROUND: The proportion of women entering pregnancy overweight or obese has been rising and, in turn, is associated with adverse maternal and fetal outcomes. Gestational weight gain (GWG) exceeding Institute of Medicine (IOM) guidelines further increases health risks and has been independently associated with postpartum weight retention. Hispanic women are disproportionately affected by overweight and obesity, but have had limited access to interventions that promote healthy lifestyles due to cultural, socioeconomic, and language barriers. Therefore, the overall goal of this randomized controlled trial is to test the efficacy of a culturally and linguistically modified, individually-tailored lifestyle intervention to reduce excess …

Involvement Of The Right Hemisphere In Reading Comprehension: A Dti Study, Tzipi Horowitz-Kraus, Yingying Wang, Elena Plante, Scott K. Holland

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

The Simple View of reading emphasizes the critical role of two factors in normal reading skills: word recognition and reading comprehension. The current study aims to identify the anatomical support for aspects of reading performance that fall within these two components. Fractional anisotropy (FA) values were obtained from Diffusion Tensor images in twenty-one typical adolescents and young adults using the Tract Based Spatial Statistics (TBSS) method. We focused on the Arcuate Fasciculus (AF) and Inferior Longitudinal Fasciculus (ILF) as fiber tracts that connect regions already implicated in the distributed cortical network for reading. Our results demonstrate dissociation between word-level and …

Implicit And Explicit Self-Esteem As Predictors Of Reactive And Proactive Aggression In Adolescent Boys And Girls, Maya Suter, Sebastien Urben, Sandrine Pihet, Cybele Bertoni, Jill De Ridder, Philippe Stephan

Journal of Adolescent and Family Health

This study aims at examining gender differences and their association with implicit and explicit self-esteem (SE), and reactive and proactive aggression in adolescents. Hundred and eighteen adolescents (60 boys and 58 girls) performed the Implicit Association Test assessing implicit SE. The Rosenberg Self-Esteem scale was used to measure explicit SE. Reactive and proactive aggression were assessed with the self-report Reactive and Proactive Aggression Scale. Results showed that girls characterized by both low explicit and implicit SE (insecure SE), or by high explicit but low implicit SE (defensive SE), showed more reactive aggression than girls reporting high explicit and implicit SE …

Relationships Between Positive Psychological Constructs And Health Outcomes In Patients With Cardiovascular Disease: A Systematic Review, Christina M. Dubois, Oriana Vesga Lopez, Eleanor E. Beale, Brian C. Healy, Julia K. Boehm, Jeff C. Huffman

Psychology Faculty Articles and Research

Depression and anxiety are well-known to be associated with adverse health outcomes in cardiac patients. However, there has been less work synthesizing the effects of positive psychological constructs (e.g., optimism) on health-related outcomes in cardiac patients. We completed a systematic review of prospective observational studies using established guidelines. A search of PubMed and PsycINFO databases from inception to January 2014 was used to identify articles. To be eligible, studies were required to assess effects of a positive psychological construct on subsequent health-related outcomes (including mortality, rehospitalizations, self-reported health status) in patients with established heart disease. Exploratory random effects' meta-analyses were …

Digital Storytelling: A Tool For Health Promotion And Cancer Awareness In Rural Alaskan Communities, Melany Cueva, Regina Kuhnley, Laura Revels, Nancy E. Schoenberg, Mark Dignan

Behavioral Science Faculty Publications

BACKGROUND: The purpose of this study was to learn community members' perspectives about digital storytelling after viewing a digital story created by a Community Health Aide/Practitioner (CHA/P).

METHODS: Using a qualitative research design, we explored digital storytelling likeability as a health-messaging tool, health information viewers reported learning and, if viewing, cancer-related digital stories facilitated increased comfort in talking about cancer. In addition, we enquired if the digital stories affected how viewers felt about cancer, as well as if viewing the digital stories resulted in health behaviour change or intent to change health behaviour.

FINDINGS: A total of 15 adult community …

Does Satisfaction With Perinatal Health Care Influence Postpartum Weight Retention?, Andreea Bente

Electronic Thesis and Dissertation Repository

The primary aim of this thesis is to identify whether satisfaction with perinatal health care encounters is associated with lower postpartum weight retention (PPWR). PPWR is the difference between postpartum and pre-pregnancy weight. Principal components analysis confirmed the validity of a summed satisfaction score representing six dimensions: information, compassion, competency, privacy, respect and decision-making. Confounders were identified using a directed acyclic graph. Multivariable linear regression models were constructed using blocks, and backwards elimination. Results reflect a mean PPWR of 2.5 kg, and high satisfaction, with more than 90% of respondents being very satisfied or satisfied on each dimension. The multivariable …

Increased Resting-State Functional Connectivity Of Visual- And Cognitive-Control Brain Networks After Training In Children With Reading Difficulties, Tzipi Horowitz-Kraus, Mark Difrancesco, Benjamin Kay, Yingying Wang, Scott K. Holland

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

The Reading Acceleration Program, a computerized reading-training program, increases activation in neural circuits related to reading.We examined the effect of the training on the functional connectivity between independent components related to visual processing, executive functions, attention, memory, and language during rest after the training. Children 8–12 years old with reading difficulties and typical readers participated in the study. Behavioral testing and functional magnetic resonance imaging were performed before and after the training. Imaging data were analyzed using an independent component analysis approach. After training, both reading groups showed increased single-word contextual reading and reading comprehension scores. Greater positive correlations between …

The Effects Of Alcohol On The Interpretation Of Social And Emotional Cues: A Field Study Of College Student Drinking, Emotion Recognition, And Perceptions Of A Hypothetical Sexual Assault, Alexander James Melkonian

Graduate Theses and Dissertations

Alcohol use and abuse among emerging adults is highly correlated with increased risk for sexual victimization. Alcohol myopia theory has been used to explain impairments in Social information processing resulting in decreased attention to environmental Social cues including risk factors for sexual assault as well as facial emotional recognition. Those with deficits in Social information processing may be at particular risk for the misperception of salient risk factors for sexual assault by victims, perpetrators, and bystanders when intoxicated. In this naturalistic field study, participants who had been consuming alcohol were recruited to engage in tasks of facial emotion recognition and …

Executive Function Predictors Of Children's Talk, Jacqlyne D. Weber

Undergraduate Honors Theses

Relatively few studies have investigated the relationship between executive functioning (EF) and language development, and even fewer have researched hot and cool EF as a predictor language development. This study is an investigation into the relationship between EF and language development in preschool aged children. More specifically, the ability for hot or cool EF to predict language, this will be the focus of the study. It was found that hot EF was a better predictor of language development in preschool aged children.

The Effects Of Sex-Role Attitudes And Group Composition On Men And Women In Groups, Valerie P. Hans, Nancy Eisenberg

Valerie P. Hans

The dual impact of group gender composition and sex-role attitudes on self-perceptions and social behavior was explored. Androgynous and stereotyped men and women were placed in groups of skewed sex composition. Subjects' self-descriptions of masculine attributes shifted significantly in the group environment. In some instances, sex role-stereotyped subjects responded most stereotypically when their gender was in the minority in the group. Differences between men and women and between androgynous and stereotyped subjects in sex role-related preferences for group roles and discussion topics were also found.

Visual Feedback Dominates The Sense Of Agency For Brain-Machine Actions, Nathan Evans, Steven Gale, Aaron Schurger, Olaf Blanke

Psychology Faculty Articles and Research

Recent advances in neuroscience and engineering have led to the development of technologies that permit the control of external devices through real-time decoding of brain activity (brain-machine interfaces; BMI). Though the feeling of controlling bodily movements (sense of agency; SOA) has been well studied and a number of well-defined sensorimotor and cognitive mechanisms have been put forth, very little is known about the SOA for BMI-actions. Using an on-line BMI, and verifying that our subjects achieved a reasonable level of control, we sought to describe the SOA for BMI-mediated actions. Our results demonstrate that discrepancies between decoded neural activity and …

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 …
