Is Postpartum Depression A Disease Of Modern Civilization?, Jennifer Hahn-Holbrook, Martie Haselton Dec 2014

Is Postpartum Depression A Disease Of Modern Civilization?, Jennifer Hahn-Holbrook, Martie Haselton

Psychology Faculty Articles and Research

Access to calorie-dense foods, medicine, and other comforts has made modern humans healthier than our prehistoric ancestors in many respects. However, the epidemics of obesity, diabetes, and cardiovascular disease suggest that there are also drawbacks to modern living. Here, we address the question of whether the dramatic cultural changes that have occurred over the past century have inflated rates of postpartum depression, adding postpartum depression to the list of diseases of modern civilization. We review evidence from cross-cultural, epidemiological, and experimental studies documenting associations between postpartum depression and modern patterns of early weaning, diets deficient in essential fatty acids, low …


Longitudinal Trajectories And Predictors Of Functional Impairment In Mild Cognitive Impairment, Alzheimer’S Disease, And Vascular Dementia, Lauren Z. Chisholm Nov 2014

Longitudinal Trajectories And Predictors Of Functional Impairment In Mild Cognitive Impairment, Alzheimer’S Disease, And Vascular Dementia, Lauren Z. Chisholm

Doctoral Dissertations

Functional disability in older persons with cognitive impairment is associated with reduced quality of life and greater mortality, health care utilization, and caregiver burden. Episodic memory, executive function, apathy, depressive symptoms, and medical burden have been identified as cross-sectional predictors of functional disability but have received little longitudinal investigation in a way that explicates how changes in these variables relates to functional disability. Functional disability also drives the distinction between the diagnoses of Mild Cognitive Impairment (MCI) and dementia; however, little is known about the rates of functional decline in these groups over time. This study utilized multi-level modeling to …

"In 1965, Hans Kornhuber and Luder Deecke made a discovery that greatly influenced the study of voluntary action. Using electroencephalography (EEG), they showed that when aligning some tens of trials to movement onset and averaging, a slowly decreasing electrical potential emerges over central regions of the brain. It starts 1 second ( s) or so before the onset of the voluntary action1 and continues until shortly after the action begins. They termed this the Bereitschaftspotential, or readiness potential (RP; Kornhuber & Deecke, 1965).2 This became the first well-established neural marker of voluntary action. In that, the RP allowed for more …


Pharmacological Interventions For Somatoform Disorders In Adults, Maria Kleinstäuber, Michael Witthöft, Andrés Steffanowski, Harm Van Marwijk, Wolfgang Hiller, Michael J. Lambert Nov 2014

Pharmacological Interventions For Somatoform Disorders In Adults, Maria Kleinstäuber, Michael Witthöft, Andrés Steffanowski, Harm Van Marwijk, Wolfgang Hiller, Michael J. Lambert

Psychology Faculty Publications

Background: Somatoform disorders are characterised by chronic, medically unexplained physical symptoms (MUPS). Although different medications are part of treatment routines for people with somatoform disorders in clinics and private practices, there exists no systematic review or meta‐analysis on the efficacy and tolerability of these medications. We aimed to synthesise to improve optimal treatment decisions. Objectives: To assess the effects of pharmacological interventions for somatoform disorders (specifically somatisation disorder, undifferentiated somatoform disorder, somatoform autonomic dysfunction, and pain disorder) in adults. Search methods: We searched the Cochrane Depression, Anxiety and Neurosis Review Group's Specialised Register (CCDANCTR) (to 17 January 2014). This register …

Van Der Wouden, Maria Kleinstäuber, Stephanie S. Leone, Berend Terluin, Mattijs E. Numans, Henriëtte E. Van Der Horst, Harm Van Marwijk

Psychology Faculty Publications

Background: Medically unexplained physical symptoms (MUPS) are physical symptoms for which no adequate medical explanation can be found after proper examination. The presence of MUPS is the key feature of conditions known as 'somatoform disorders'. Various psychological and physical therapies have been developed to treat somatoform disorders and MUPS. Although there are several reviews on non‐pharmacological interventions for somatoform disorders and MUPS, a complete overview of the whole spectrum is missing. Objectives: To assess the effects of non‐pharmacological interventions for somatoform disorders (specifically somatisation disorder, undifferentiated somatoform disorder, somatoform disorders unspecified, somatoform autonomic dysfunction, pain disorder, and alternative somatoform diagnoses …

“Me & My Brain”: Exposing NeuroscienceʼS Closet Dualism, Liad Mudrik, Uri Maoz Sep 2014

“Me & My Brain”: Exposing NeuroscienceʼS Closet Dualism, Liad Mudrik, Uri Maoz

Psychology Faculty Articles and Research

Our intuitive concept of the relations between brain and mind is increasingly challenged by the scientific world view. Yet, although few neuroscientists openly endorse Cartesian dualism, careful reading reveals dualistic intuitions in prominent neuroscientific texts. Here, we present the “double-subject fallacy”: treating the brain and the entire person as two independent subjects who can simultaneously occupy divergent psychological states and even have complex interactions with each other—as in “my brain knew before I did.” Although at first, such writing may appear like harmless, or even cute, shorthand, a closer look suggests that it can be seriously misleading. Surprisingly, this confused …


Depicting Estimates Using The Intercept In Meta-Regression Models: The Moving Constant Technique, Blair T. Johnson Dr., Tania B. Huedo-Medina Dr. Aug 2014

Depicting Estimates Using The Intercept In Meta-Regression Models: The Moving Constant Technique, Blair T. Johnson Dr., Tania B. Huedo-Medina Dr.

Blair T. Johnson

In any scientific discipline, the ability to portray research patterns graphically often aids greatly in interpreting a phenomenon. In part to depict phenomena, the statistics and capabilities of meta-analytic models have grown increasingly sophisticated. Accordingly, this article details how to move the constant in weighted meta-analysis regression models (viz. “meta-regression”) to illuminate the patterns in such models across a range of complexities. Although it is commonly ignored in practice, the constant (or intercept) in such models can be indispensible when it is not relegated to its usual static role. The moving constant technique makes possible estimates and confidence intervals at …


A Revised Method For Measuring Distraction By Tactile Stimulation [V1; Ref Status: Indexed, Http://F1000r.Es/42o], Jacqueline R. Schechter, Deanna J. Greene, Jonathan M. Koller, Kevin J. Black Aug 2014

A Revised Method For Measuring Distraction By Tactile Stimulation [V1; Ref Status: Indexed, Http://F1000r.Es/42o], Jacqueline R. Schechter, Deanna J. Greene, Jonathan M. Koller, Kevin J. Black

Kevin J. Black, MD

Sensory hypersensitivity (SH) refers to the tendency to attend to subtle stimuli, to persist in attending to them, and to find them noxious. SH is relatively common in several developmental disorders including Tourette Syndrome and Chronic Tic Disorder (TS/CTD). This study was an attempt to quantify the extent to which a mild tactile stimulus distracts one’s attention in TS/CTD. Fourteen adults with TS/CTD and 14 tic-free control subjects completed questionnaires regarding SH and ADHD, and TS/CTD subjects completed self-report measures of current and past tic disorder symptoms and of current obsessions and compulsions. All subjects performed a sustained attention choice …


Belief In The Efficacy Of Psychotherapy (Bep): Psychometric Scale Development And Examination Of Theoretical Correlates, Erin Gray Volpe Aug 2014

Belief In The Efficacy Of Psychotherapy (Bep): Psychometric Scale Development And Examination Of Theoretical Correlates, Erin Gray Volpe

Doctoral Dissertations

This study develops a psychometric scale measuring the extent to which an individual expects psychotherapy to be effective: The Belief in the Efficacy of Psychotherapy (BEP). Based in the research that describes expectations for therapy as process expectations or outcome expectations, the BEP scale is developed to measure outcome expectations for therapy exclusively (i.e., is psychotherapy helpful?). Current expectancy measures vastly underrepresent outcome expectations in particular, and BEP will be the first to focus solely on outcome expectations. Additionally, the proposed BEP scale measures the general cultural belief system (i.e., non-patients) and their beliefs about psychotherapy and therapists specifically, …


Sleep-Related Arousal And Spontaneous Movement Properties In Methadone-Exposed Neonates: A Videographic Assessment On The First Or Second Postnatal Night, Hira Shrestha Aug 2014

Sleep-Related Arousal And Spontaneous Movement Properties In Methadone-Exposed Neonates: A Videographic Assessment On The First Or Second Postnatal Night, Hira Shrestha

Electronic Theses and Dissertations

Prenatal substance exposure such as alcohol, nicotine, and opiates is known to modulate autonomic regulatory function during sleep, and to decrease arousability and spontaneous movements (SM). SM during sleep may reflect a protective mechanism for immature patterns of arousals. Neurodevelopmental compromise in sleep and arousal systems may underlie sudden infant death syndrome (SIDS) risk in which infants expire during sleep. Previous studies from our laboratory found abnormal patterns of neonatal arousal, sleep fragmentation, and deficits in sleep-related SM in infants with prenatal alcohol exposure. In this study, prenatal exposure to methadone was hypothesized to disrupt the development of sleep and …


Grandfamilies Outcome Workgroup’S (Grow) Review Of Grandfamilies Support Groups: An Examination Of Concepts, Goals, Outcomes And Measures, Kerry A. Littlewood Jul 2014

Grandfamilies Outcome Workgroup’S (Grow) Review Of Grandfamilies Support Groups: An Examination Of Concepts, Goals, Outcomes And Measures, Kerry A. Littlewood

GrandFamilies: The Contemporary Journal of Research, Practice and Policy

A support group is the most widely used intervention for grandparents and other relatives raising children. Support groups require few resources to establish and are relatively inexpensive to implement. Despite the popularity of support groups for grandfamilies, there is little evidence evaluating their effectiveness to improve the lives of its members. In response to this issue and to support outcome-based research in the field, the Grandfamilies Outcome Workgroup (GrOW) was established. This study highlights GrOW’s review of the literature on the effectiveness of support groups for grandfamilies. Next, the GrOW Inventory of Support Groups (GrOW Inventory) was developed to explore …


Residential Treatment For Combat-Related Posttraumatic Stress Disorder: Identifying Trajectories Of Change And Predictors Of Treatment Response, Joseph M. Currier, Jason M. Holland, Kent D. Drescher Jul 2014

Residential Treatment For Combat-Related Posttraumatic Stress Disorder: Identifying Trajectories Of Change And Predictors Of Treatment Response, Joseph M. Currier, Jason M. Holland, Kent D. Drescher

Psychology Faculty Research

Background

Combat-related posttraumatic stress disorder (PTSD) can be a difficult condition to treat and has been associated with serious medical and economic issues among U.S. military veterans. Distinguishing between treatment responders vs. non-responders in this population has become an important public health priority. This study was conducted to identify pre-treatment characteristics of U.S. veterans with combat-related PTSD that might contribute to favorable and unfavorable responses to high value treatments for this condition.

Method

This study focused on 805 patients who completed a VHA PTSD residential program between 2000 and 2007. These patients completed the PTSD Clinical Checklist at pre-treatment, post-treatment, …


Pregnancy Anxiety And Prenatal Cortisol Trajectories, Heidi S. Kane, Christine Dunkel Schetter, Laura M. Glynn, Calvin J. Hobel, Curt A. Sandman Jul 2014

Pregnancy Anxiety And Prenatal Cortisol Trajectories, Heidi S. Kane, Christine Dunkel Schetter, Laura M. Glynn, Calvin J. Hobel, Curt A. Sandman

Psychology Faculty Articles and Research

Pregnancy anxiety is a potent predictor of adverse birth and infant outcomes. The goal of the current study was to examine one potential mechanism whereby these effects may occur by testing associations between pregnancy anxiety and maternal salivary cortisol on 4 occasions during pregnancy in a sample of 448 women. Higher mean levels of pregnancy anxiety over the course of pregnancy predicted steeper increases in cortisol trajectories compared to lower pregnancy anxiety. Significant differences between cortisol trajectories emerged between 30 to 31 weeks of gestation. Results remained significant when adjusted for state anxiety and perceived stress. Neither changes in pregnancy …


Seeing With Sound: Investigating The Behavioural Applications And Neural Correlates Of Human Echolocation, Jennifer L. Milne Jun 2014

Seeing With Sound: Investigating The Behavioural Applications And Neural Correlates Of Human Echolocation, Jennifer L. Milne

Electronic Thesis and Dissertation Repository

Some blind humans use the reflected echoes from self-produced signals to perceive their silent surroundings. Although the use of echolocation is well documented in animals such as bats and dolphins, comparatively little is known about human echolocation. The overarching goal of the work presented in this thesis was to shed light on some of the basic functions of human echolocation, including the perception of the shape, size, and material. I addressed these aspects of echolocation using behavioural psychophysics and neuroimaging.

In Chapter 2 I show that blind echolocators were able to accurately identify the shape of 2D objects, but that …


Relationship Between Sensory Sensitivities And Cognitive And Adaptive Abilities In Children With Autism Spectrum Disorders, Laura Pendergast May 2014

Relationship Between Sensory Sensitivities And Cognitive And Adaptive Abilities In Children With Autism Spectrum Disorders, Laura Pendergast

Honors Scholar Theses

Sensory sensitivities are widely reported among individuals with ASD. These sensory sensitivities can be classified as over-responsivity, under-responsivity, or seeking of sensory stimulation. Following recent changes in the diagnostic criteria, sensory sensitivities are considered a key feature of the behavioral phenotype of ASDs. Despite their significance, sensory sensitivities have been largely underestimated. Therefore, more research in this area may reveal important information about the influence of sensitivities on functioning, as well as the underlying causes of the symptoms. This study investigated a possible relationship between sensory sensitivities and cognitive and adaptive abilities in children with ASD. The sample included 29 …

Department of Psychology: Faculty Publications

Oxidative stress is a common hallmark of neuronal cell death associated with neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, as well as brain stroke/ischemia and traumatic brain injury. Increased accumulation of reactive species of both oxygen (ROS) and nitrogen (RNS) has been implicated inmitochondrial dysfunction, energy impairment, alterations in metal homeostasis and accumulation of aggregated proteins observed in neurodegenerative disorders, which lead to the activation/modulation of cell death mechanisms that include apoptotic, necrotic and autophagic pathways. Thus, the design of novel antioxidant strategies to selectively target oxidative stress and redox imbalance might represent important therapeutic approaches against neurological disorders. …

Possible Psychosocial Benefits Of Having A Sibling With A Disability, Jenna M. Talbott Apr 2014

Possible Psychosocial Benefits Of Having A Sibling With A Disability, Jenna M. Talbott

Senior Honors Theses

Possible psychosocial benefits resulting from exposure to siblings with disabilities are investigated in the current study. Previous literature has generally overlooked the possibility of psychosocial benefits by exclusively focusing on the negative effects of having a sibling with disabilities. Contact theory suggests that the increased exposure to individuals with disabilities should increase positive attitude toward those who are struggling with disadvantages. This investigation hypothesized that this tendency would be manifested as elevated empathy and compassion in individuals who have siblings with disabilities, and that these traits would be influenced by certain demographic variables. A survey was distributed, and the responses …


Changes In Sleep Time And Sleep Quality Across The Ovulatory Cycle As A Function Of Fertility And Partner Attractiveness, Brooke N. Jenkins, Elizabeth G. Pillsworth, Aaron T. Goetz Apr 2014

Changes In Sleep Time And Sleep Quality Across The Ovulatory Cycle As A Function Of Fertility And Partner Attractiveness, Brooke N. Jenkins, Elizabeth G. Pillsworth, Aaron T. Goetz

Psychology Faculty Articles and Research

Research suggests that near ovulation women tend to consume fewer calories and engage in more physical activity; they are judged to be more attractive, express greater preferences for masculine and symmetrical men, and experience increases in sexual desire for men other than their primary partners. Some of these cycle phase shifts are moderated by partner attractiveness and interpreted as strategic responses to women’s current reproductive context. The present study investigated changes in sleep across the ovulatory cycle, based on the hypothesis that changes in sleep may reflect ancestral strategic shifts of time and energy toward reproductive activities. Participants completed a …


Secondary Traumatic Stress And Alexithymia In High-Risk Professionals, Matthew R. J. Vandermeer Apr 2014

Secondary Traumatic Stress And Alexithymia In High-Risk Professionals, Matthew R. J. Vandermeer

Electronic Thesis and Dissertation Repository

This study investigated the role that cognitive deficits in emotional processing (i.e., alexithymia) play in the development of traumatic responses, such as secondary traumatic stress (STS), following work with clients who have experienced trauma. Using a prospective cohort of novice counselling psychology and pre-service education students, participants were measured for traits of alexithymia and STS before and after their first practicum placements. Elevated rates of STS consistent with a diagnosis of post-traumatic stress disorder were identified in participants following initial practicum placement. Correlation analyses demonstrated that alexithymia and alexithymia symptom clusters were significantly, and robustly, associated with STS and STS …

An Exploratory Study Of College Students’ Attitudes About Ecstasy, Rachel Reingold Apr 2014

An Exploratory Study Of College Students’ Attitudes About Ecstasy, Rachel Reingold

Senior Theses and Projects

In a recent survey of 18-35 year olds, 15% reported using ecstasy (Businelle et al., 2009) and many emerging adults viewed it as “safer” than other illicit drugs, with limited negative consequences (Bahora et al., 2009). Although numerous quantitative studies have explored the topic of ecstasy use in college students, there is limited qualitative research, most of which is limited to users. Thus, in the current study, we used a focus group methodology to better understand users’ and nonusers’ knowledge, expectations, and perceived risks of ecstasy use, for the purpose of informing prevention efforts on college campuses. Twenty-four college students …


Mindfulness And Its Ability To Alleviate State And Trait Anxiety In College Students, Kaitlyn Mascioli Apr 2014

Mindfulness And Its Ability To Alleviate State And Trait Anxiety In College Students, Kaitlyn Mascioli

Senior Theses and Projects

Society today puts extreme pressure on individuals to take on a magnitude of daily responsibilities in order to be successful. We are pushed beyond our limits both mentally and physically, which results in heightened state and trait anxiety. Adopting the theory of mindfulness teaches us to live in the present moment and not criticize our thoughts (Bormann et. al, 2013). The current study tests the effects of daily mindfulness meditation on state and trait anxiety as measured by the State-Trait Anxiety Inventory. Participants were Trinity College students that engaged in formal meditation sessions twice a week, but maintained the practice …


The Efficacy Of Mathematics Education, Eric Geimer Feb 2014

The Efficacy Of Mathematics Education, Eric Geimer

The STEAM Journal

Evidence supports the notion that mathematics education in the United States is inadequate. There is also evidence that mathematics education deficiencies extend internationally. The worldwide mathematics education deficit appears large enough that improving student performance in this educational problem area could yield great economic benefit. To improve the efficacy of mathematics education, education’s root problems must first be understood. Often supposed educational root problems are considered and contrasted against potential deficiencies of mathematics methodologies and curricula that are based on mainstream educational philosophies. The educational philosophies utilized to form early-grade mathematics methodologies and related curricula are judged to be the …

Meta-Analysis Of Social-Personality Psychological Research, Blair T. Johnson, Alice H. Eagly Jan 2014

Meta-Analysis Of Social-Personality Psychological Research, Blair T. Johnson, Alice H. Eagly

CHIP Documents

This publication provides a contemporary treatment of the subject of meta-analysis in relation to social-personality psychology. Meta-analysis literally refers to the statistical pooling of the results of independent studies on a given subject, although in practice it refers as well to other steps of research synthesis, including defining the question under investigation, gathering all available research reports, coding of information about the studies and their effects, and interpretation/dissemination of results. Discussed as well are the hallmarks of high-quality meta-analyses.


Hispanic Construction Workers And Assertiveness Training, Pramen Shrestha, Nancy Menzel Jan 2014

Hispanic Construction Workers And Assertiveness Training, Pramen Shrestha, Nancy Menzel

Nursing Faculty Publications

BACKGROUND: Hispanic (Latino) construction workers experience disparities in occupational death and injury rates in the United States. The cultural value of respect for those in authority may hinder these workers from requesting safe working conditions from supervisors.

OBJECTIVE: To evaluate whether Hispanic construction workers in Las Vegas, Nevada found assertiveness training more useful than non-Hispanic trainees and whether or not they practiced this behavior at work after the training.

METHODS: An assertiveness training simulation was part of fall prevention classes offered to area construction workers. Eight weeks after the training, participants were interviewed by telephone about class topics they found …


Anxiety And The Imposter Phenomenon Among Graduate Students In Online Versus Traditional Programs, Christy B. Fraenza Jan 2014

Anxiety And The Imposter Phenomenon Among Graduate Students In Online Versus Traditional Programs, Christy B. Fraenza

2010-2016 Archived Posters

This study compared online and traditional students on measures of imposter phenomenon (IP), anxiety, and perfectionism. Traditional students had significantly higher IP scores. Perfectionism was the strongest predictor of IP scores. Because the scale for perfectionism explored socially prescribed perfectionism, it seems to suggest an underlying social component to IP.
