Visual Acceleration Perception For Simple And Complex Motion Patterns., Alexandra S Mueller, Brian Timney

Brain and Mind Institute Researchers' Publications

Humans are able to judge whether a target is accelerating in many viewing contexts, but it is an open question how the motion pattern per se affects visual acceleration perception. We measured acceleration and deceleration detection using patterns of random dots with horizontal (simpler) or radial motion (more visually complex). The results suggest that we detect acceleration better when viewing radial optic flow than horizontal translation. However, the direction within each type of pattern has no effect on performance and observers detect acceleration and deceleration similarly within each condition. We conclude that sensitivity to the presence of acceleration is generally …

Structural Brain Injury In Patients With Disorders Of Consciousness: A Voxel-Based Morphometry Study., Pieter Guldenmund, Andrea Soddu, Katherine Baquero, Audrey Vanhaudenhuyse, Marie-Aurélie Bruno, Olivia Gosseries, Steven Laureys, Francisco Gómez

Brain and Mind Institute Researchers' Publications

MAIN OBJECTIVE: Disorders of consciousness (DOC; encompassing coma, vegetative state/unresponsive wakefulness syndrome (VS/UWS) and minimally conscious state minus/plus (MCS-/+)) are associated with structural brain injury. The extent of this damage remains poorly understood and merits a detailed examination using novel analysis techniques. Research design/methods and procedures: This study used voxel-based morphometry (VBM) on structural magnetic resonance imaging scans of 61 patients with DOC to examine grey and white matter injury associated with DOC, time spent in DOC, aetiology and diagnosis.

MAIN OUTCOMES AND RESULTS: DOC and time spent in DOC were found to be associated with widespread structural brain injury, …

Correlation Between Resting State Fmri Total Neuronal Activity And Pet Metabolism In Healthy Controls And Patients With Disorders Of Consciousness., Andrea Soddu, Francisco Gómez, Lizette Heine, Carol Di Perri, Mohamed Ali Bahri, Henning U Voss, Marie-Aurélie Bruno, Audrey Vanhaudenhuyse, Christophe Phillips, Athena Demertzi, Camille Chatelle, Jessica Schrouff, Aurore Thibaut, Vanessa Charland-Verville, Quentin Noirhomme, Eric Salmon, Jean-Flory Luaba Tshibanda, Nicholas D Schiff, Steven Laureys

Brain and Mind Institute Researchers' Publications

INTRODUCTION: The mildly invasive 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) is a well-established imaging technique to measure 'resting state' cerebral metabolism. This technique made it possible to assess changes in metabolic activity in clinical applications, such as the study of severe brain injury and disorders of consciousness.

OBJECTIVE: We assessed the possibility of creating functional MRI activity maps, which could estimate the relative levels of activity in FDG-PET cerebral metabolic maps. If no metabolic absolute measures can be extracted, our approach may still be of clinical use in centers without access to FDG-PET. It also overcomes the problem of recognizing individual …

Microglia And Neurons In The Hippocampus Of Migratory Sandpipers., C G Diniz, N G M Magalhães, A A Sousa, C Santos Filho, D G Diniz, C M Lima, M A Oliveira, D C Paulo, P D C Pereira, D F Sherry, C W Picanço-Diniz

Brain and Mind Institute Researchers' Publications

The semipalmated sandpiper Calidris pusilla and the spotted sandpiper Actitis macularia are long- and short-distance migrants, respectively. C. pusilla breeds in the sub-arctic and mid-arctic tundra of Canada and Alaska and winters on the north and east coasts of South America. A. macularia breeds in a broad distribution across most of North America from the treeline to the southern United States. It winters in the southern United States, and Central and South America. The autumn migration route of C. pusilla includes a non-stop flight over the Atlantic Ocean, whereas autumn route of A. macularia is largely over land. Because of …

Context-Dependent Egr1 Expression In The Avian Hippocampus., Stephanie L Grella, Mélanie F Guigueno, David J White, David F Sherry, Diano F Marrone

Brain and Mind Institute Researchers' Publications

In mammals, episodic memory and spatial cognition involve context-specific recruitment of unique ensembles in the hippocampal formation (HF). Despite their capacity for sophisticated spatial (e.g., for migration) and episodic-like (e.g., for food-caching) memory, the mechanisms underlying contextual representation in birds is not well understood. Here we demonstrate environment-specific Egr1 expression as male brown-headed cowbirds (Molothrus ater) navigate environments for food reward, showing that the avian HF, like its mammalian counterpart, recruits distinct neuronal ensembles to represent different contexts.

Distinct Visual Processing Of Real Objects And Pictures Of Those Objects In 7- To 9-Month-Old Infants., Theresa M Gerhard, Jody C Culham, Gudrun Schwarzer

Brain and Mind Institute Researchers' Publications

The present study examined 7- and 9-month-old infants' visual habituation to real objects and pictures of the same objects and their preferences between real and pictorial versions of the same objects following habituation. Different hypotheses would predict that infants may habituate faster to pictures than real objects (based on proposed theoretical links between behavioral habituation in infants and neuroimaging adaptation in adults) or to real objects vs. pictures (based on past infant electrophysiology data). Sixty-one 7-month-old infants and fifty-nine 9-month-old infants were habituated to either a real object or a picture of the same object and afterward preference tested with …

Equal-Magnitude Size-Weight Illusions Experienced Within And Between Object Categories., Gavin Buckingham, Melvyn A Goodale, Justin A White, David A Westwood

Brain and Mind Institute Researchers' Publications

In the size-weight illusion (SWI), small objects feel heavier than larger objects of the same mass. This effect is typically thought to be a consequence of the lifter's expectation that the large object will outweigh the small object, because objects of the same type typically get heavier as they get larger. Here, we show that this perceptual effect can occur across object category, where there are no strong expectations about the correspondence between size and mass. One group of participants lifted same-colored large and small cubes with the same mass as one another, while another group lifted differently-colored large and …

Working Memory Training And Speech In Noise Comprehension In Older Adults., Rachel V Wayne, Cheryl Hamilton, Julia Jones Huyck, Ingrid S Johnsrude

Brain and Mind Institute Researchers' Publications

Understanding speech in the presence of background sound can be challenging for older adults. Speech comprehension in noise appears to depend on working memory and executive-control processes (e.g., Heald and Nusbaum, 2014), and their augmentation through training may have rehabilitative potential for age-related hearing loss. We examined the efficacy of adaptive working-memory training (Cogmed; Klingberg et al., 2002) in 24 older adults, assessing generalization to other working-memory tasks (near-transfer) and to other cognitive domains (far-transfer) using a cognitive test battery, including the Reading Span test, sensitive to working memory (e.g., Daneman and Carpenter, 1980). We also assessed far transfer to …

Medial Prefrontal And Anterior Insular Connectivity In Early Schizophrenia And Major Depressive Disorder: A Resting Functional Mri Evaluation Of Large-Scale Brain Network Models., Jacob Penner, Kristen A Ford, Reggie Taylor, Betsy Schaefer, Jean Théberge, Richard W J Neufeld, Elizabeth A Osuch, Ravi S Menon, Nagalingam Rajakumar, John M Allman, Peter C Williamson

Brain and Mind Institute Researchers' Publications

Anomalies in the medial prefrontal cortex, anterior insulae, and large-scale brain networks associated with them have been proposed to underlie the pathophysiology of schizophrenia and major depressive disorder (MDD). In this study, we examined the connectivity of the medial prefrontal cortices and anterior insulae in 24 healthy controls, 24 patients with schizophrenia, and 24 patients with MDD early in illness with seed-based resting state functional magnetic resonance imaging analysis using Statistical Probability Mapping. As hypothesized, reduced connectivity was found between the medial prefrontal cortex and the dorsal anterior cingulate cortex and other nodes associated with directed effort in patients with …

The Semantic Memory Imaging In Late Life Pilot Study, Michael Adam Sugarman

Wayne State University Dissertations

Introduction: Several functional magnetic resonance imaging (fMRI) studies have analyzed the famous name discrimination task (FNDT), an uncontrolled semantic memory probe requiring discrimination between famous and unfamiliar individuals. Completion of this simple task recruits a semantic memory network that has shown utility in determining risk for Alzheimer's disease (AD). Specific semantic memory probes using biographical information associated with famous individuals may build on previous findings and yield superior information regarding risk for AD.

Method: Sixteen cognitively intact elders completed the FNDT and two novel tasks during fMRI: Categories (matching famous individuals to occupational categories) and Attributes (matching famous individuals to …

Burnout’S Prevalence Estimations: A House Of Cards?, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

Elmariah et al. (2016) found that 65% of the internal medicine residents who were assessed suffered from burnout. We have 3 concerns about the conclusion. First, the authors used a cutoff score on a burnout measure that is problematic because (a) it is devoid of theoretical or clinical grounding and (b) burnout items were formatted in an unorthodox manner, and (c) including residents who responded "neutral" to a symptom item among those identified as burned out. Second, the authors identified as burned out residents who worked on the night float rotation although the data suggest otherwise. Third information on symptom …

On The Dead End Of Current Research On Burnout's Prevalence, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

Dimou et al. (2016) concluded that >50% of surgeons experience burnout. For three reasons, we think that such conclusions are unwarranted. First, there are no consensual or binding diagnostic criteria for burnout. Second, recent research (e.g., Bianchi, Schonfeld, & Laurent, 2015) suggests that burnout is actually a depressive syndrome. Finally, we note that researchers’ recommendations about stress-reducing organizational changes often remain incantatory because they insufficiently consider the economic issues and macrosocial power relationships that can hamper the recommendations’ implementation. Current practices in burnout research have led to an accumulation of results, the clinical meaning of which is obscure.

Burnout-Depression Overlap: A Study Of New Zealand Schoolteachers, Renzo Bianchi, Irvin Sam Schonfeld, Eric Mayor, Eric Laurent

Publications and Research

We examined the overlap of burnout with depression in a sample of 184 New Zealand schoolteachers. Burnout and depressive symptoms were strongly correlated with each other (r = .73; disattenuated correlation: .82) and moderately correlated with dysfunctional attitudes, ruminative responses, and pessimistic attributions. All the participants with high frequencies of burnout symptoms were identified as clinically depressed. Suicidal ideation was reported by 36% of those participants. Three groups of teachers emerged from a two-step cluster analysis: “low burnout-depression,” “medium burnout-depression,” and “high burnout-depression.” The correlation between the affective-cognitive and somatic symptoms of depression was similar in strength to the burnout-depression …

An Analysis Of Virtual Place Learning/Navigation In Children And Young Adults Prenatally Exposed To Alcohol, Neil Christopher Dodge

Wayne State University Dissertations

Fetal alcohol spectrum disorder refers to the spectrum of disorders resulting from prenatal alcohol exposure and is the leading cause of preventable mental retardation. Rodent studies have found that prenatal alcohol exposure impairs performance on the Morris water maze. This task requires the rodent to use distal room cues to locate a hidden platform in a pool of opaque water. Successful performance on this task is dependent upon hippocampal function. Rodents prenatally exposed to alcohol are impaired on the Morris water maze and show damage to hippocampal neurons. A human analogue of the Morris water maze, the virtual water maze …

The Impact Of Age On Workplace Motivation: A Person-Centered Perspective, Keith Lynn Zabel

Wayne State University Dissertations

The present study used the person-centered approach to examine how profiles based upon six different age conceptualizations differentially impact workplace motivation. In the first known study to examine all conceptualizations of age simultaneously, results suggested the age conceptualizations of subjective age and health significantly impact growth motives for older workers, but not social or security motives. Results suggest social motives are influenced more by chronological age as opposed to other conceptualizations of age. Implications for practitioners in designing and implementing HR activities (e.g., succession planning) and researchers in utilizing all the conceptualizations of age and studying workplace interventions are discussed.

Diabetes Interaction Study: Communicating Understanding And Social Support, Dana K. May

Wayne State University Dissertations

The current study evaluated a brief individualized feedback intervention developed to improve communication style of parents with an adolescent with type 1 diabetes. Seventy-nine parent-adolescent dyads (13-18 years) were randomized to receive a single session of brief feedback to target parental person-centered communication skills (n = 39) or to receive an educational comparison group (n = 40). Families were asked to discuss a diabetes related problem. A clinician concurrently rated the parent’s communication skills to identify communication strengths and weaknesses. Parents in the feedback group received feedback on their use of person-centered communication during the conversation using motivational interviewing techniques. …

Management Safety Climate And Violence Prevention Climate: A Mediational Model For Healthcare Employee Outcomes, Lydia Hamblin Hamblin

Wayne State University Dissertations

Workplace violence is defined as aggressive acts against employees ranging from verbal abuse, threats, and bullying, to physical assault (OSHA, 2002; Jackson, Clare, & Mannix, 2002). The two purposes of this study were (1) to differentiate two specific forms of psychological climate related to workplace violence on a work unit: Violence Prevention Climate (VPC) and Management Safety Climate (MSC), and (2) to test a causal model focusing on the relationship between these climates and their effects on relevant outcomes for at-risk employees in the healthcare industry. MSC was expected to partially mediate the effects of VPC on four outcomes: work …

Quality Of Life And Athletic Participation Assessment In Children And Adolescents With Congenital Heart Disease, Kayla Stuckey

Honors Program Theses

Just under 1% of infants are born with a heart defect [congenital heart disease (CHD)], and as a result of treatment and early diagnosis, 85% of these children survive into adulthood. Few studies have investigated the quality of life, global happiness, and athletic participation in pediatric populations, especially with respect to those who have CHD. In 2010, the number of people aged 0-18 years who had CHD was estimated to be between 1,905,000 and 2,102,000, and there are varying qualities of life that these children experience based on disease severity. In addition to patients who are born with CHD, children …

The Effects Of Courtship And Pairing Behavior On The Nonapeptide And Noradrenergic Systems Of Adult Male And Female Zebra Finches, Erin Lowrey Ondercin

Wayne State University Dissertations

Social relationships are complex and likely involve the multiple neural circuits, including those involved in learning, memory, motivation, and attention. Two neurotransmitter pathways highly involved in these neural circuits are norepinephrine (NE) and the nonapeptides, vasopressin (AVP) and oxytocin (OT). There is extensive research implicating a role for the nonapeptides in trust, sociality, parental care, and romantic relationships. There is little direct evidence for the role of nonapeptides in monogamous relationships in any species other than the prairie vole (Goodson 2013). However, there is evidence that nonapeptides are important in pair bonding for both male and female zebra finches (Lowrey …

Clinician Mindfulness Practice And The Implications For Burnout Mitigation: Mindfulness As A Values Component Of Self-Care, Stephanie Wachter

Counselor Education Theses

Over 40 years after Freudenberger (1975) introduced the term, burnout remains a critical concern among mental health clinicians. Many researchers in recent decades have focused their attention upon burnout prevention, exploring the practices of clinicians, and proposing the possible factors at-play in counselor, therapist, and social workers’ resiliency in the face of vicarious trauma, and other burnout factors. Mindfulness is a growing area of interest in this course of study, with yoga, meditation, and visualizations as some of the exercises associated with the practice and its apparent benefits. This qualitative study examined mindfulness as a component of mental health clinician …

Archives of Assessment Psychology

The aim of this study was to test whether a Czech version of the Trail Making Test (TMT) normative data yield scores that approximate those based on English (North American) and Spanish normative samples. In all samples, TMT Parts A and B were administered according to the guidelines. Completion times for healthy adults from the Czech Republic (n = 422, Bezdicek et al., 2012), the United States (n = 325, Schretlen et al., 2008) and Spain (n = 348, Ojeda, Pena, unpublished data), stratified for age and education, were compared. Czechs took less time to complete TMT-B than English and …

Fear Of Alzheimer's Disease And Its Role In Memory Monitoring And Control, Annalise Marie Rahman

Wayne State University Dissertations

Introduction: Fear of Alzheimer’s disease (FAD), or Anticipatory Dementia, is a healthy adult’s misinterpretation of everyday memory failures as indicators of developing dementia. The current study investigated the construct of FAD and aimed to contextualize FAD within the Health Belief Model through development of a new scale, the Anticipatory Dementia Index (ADI). The study also assessed the relationship between FAD and metacognitive monitoring and metacognitive control.

Methods: 94 cognitively-intact community-dwelling older adults with and without a history of family history of AD completed questionnaires regarding their subjective memory complaints, state and trait anxiety, depression, and multiple measures of FAD, including …

Child Maltreatment, Problem Alcohol Use And Physical Revictimization: Examining Longitudinal Trajectories In A Nationally Representative Sample, Kathryn Mariah Zumberg Smith

Wayne State University Dissertations

Past investigations examining the relationships between child maltreatment, alcohol use and physical revictimization have been limited by their use of cross-sectional designs and their focus on childhood sexual abuse and sexual revictimization. In addition, there is a paucity of epidemiological studies examining child maltreatment, alcohol use, and physical revictimization. The present study sought to address these limitations by examining relationships between child maltreatment, problem alcohol use, and physical revictimization in a nationally representative sample. Data were analyzed from the public-use data set of the National Longitudinal Study of Adolescent to Adult Health (Add health; Harris & Udry, 2014), waves I-IV. …

Airline Pilots In Recovery From Alcoholism: A Quantitative Study Of Cognitive Change, Heather Christina Hamilton

Walden Dissertations and Doctoral Studies

In order to perform their duties, airline pilots must have no clinical diagnosis of mental illness or any substance use disorder. However, provisions have been in place since the 1970s that provide for a return to work for airline pilots with alcohol problems. To date, over 5,000 airline pilots have undergone rehabilitation for Alcohol Use Disorder (AUD) and successfully returned to work. An important gap in the literature remains with regard to what extent improvements in cognitive performance may be experienced by airline pilots who complete treatment and to what extent age influences the amount of change. This study examined …

Public Health Leaders' Perceptions Of And Attitudes Concerning Eating Disorders, Karin L. Lightfoot

Walden Dissertations and Doctoral Studies

Eating disorders are associated with high mortality rates. Most eating disorder prevention research is conducted within the fields of psychology and psychiatry, not in public health. This gap in public health research can lead to insufficient attention to the root causes of eating disorders and minimal upstream prevention efforts. The purpose of this phenomenological study was to identify public health leaders' perceptions of and attitudes concerning eating disorders as a public health issue. Objectification theory was used to describe how societal expectations have created an environment in which people's self-worth is based on their outward physical appearance. Ecological theory was …

Outcomes Of Aggression Replacement Training For U.S. Adolescents In Residential Facilities, Coral Ann Ondrus

Walden Dissertations and Doctoral Studies

A National Survey indicated that 1.6 million adolescents in the U.S. were arrested in 2010 and 1.5 million in 2011 for erratic aggressive behaviors, thus showing a decline from the 2.18 million adolescent arrests in 2007. Residential facilities in the state of Pennsylvania offer a group intervention called Aggression Replacement Training (ART) to help adjudicated adolescents regain control of erratic behaviors. The purpose of this study was to examine the extent to which level of group participation in ART and certain demographic factors (age, gender, ethnicity, family socioeconomic status, parental involvement, and education) predict decreased aggression and increased anger control …

Master's Students' Self-Assessment Of Competency In Grief Education And Training In Cacrep-Accredited Counseling Programs, Jane Earline Wood

Walden Dissertations and Doctoral Studies

Counseling can promote positive outcomes for grieving clients by addressing personal loss and helping the client process their grief. However, a lack of understanding on the part of counselors of how people grieve may result in negative client outcomes such as psychological stress, poor health, or an increased risk of depression. Education and training in grief counseling can improve counselors' problem recognition and skills in treatment planning. The purpose of this study was to examine whether Council for Accreditation of Counseling and Related Educational Programs (CACREP) master's degree counseling students view themselves as having been adequately trained in grief theories …

Diminishing Stigma Sentiments In Individuals With Depression: Sociopsychological Predictors Of Deflecting And Challenging Coping Orientations, Jennifer Marie Lee

Walden Dissertations and Doctoral Studies

Individuals who suffer from depression can be stigmatized by labeling and resort to negative stigma coping orientations such as secrecy and withdrawal, resulting in internalized self-stigma. Self-stigma can have negative effects such as low self-esteem, low self-efficacy, isolation, and feeling like a failure. Guided by modified labeling theory, the purpose of this study was to fill a gap in the literature on predictors of two orientations (challenging and deflecting) of positive stigma coping. Challenging stigma involves taking action, and deflecting is a cognitive strategy; both are used to positively cope with the stigma of mental illness. Predictors included symptom severity, …

The Effect Of Media Literacy Training On The Self-Esteem And Body-Satisfaction Among Fifth Grade Girls, Holly Mathews

Walden Dissertations and Doctoral Studies

Repeated exposure to media images that portray women as sex objects can have negative long-term effects on self-esteem beginning in preadolescence. Negative effects include decreased feelings of competence, increased focus on appearance, increased body dissatisfaction, and limited achievement in domains not related to appearance. There is a gap in the literature examining if media literacy training can mitigate the negative effects of exposure to sexualized media content. Festinger's social comparison theory and Vygotsky's theory of cognitive development provided the framework for this study. A quasi-experimental pre-post-test design was used to examine the interaction of media literacy training and time of …

Evaluating The Implications Of Parental Mental Illness For Children Using An Ecological Perspective, Jessica Elizabeth-Rose Carroll

Walden Dissertations and Doctoral Studies

Researchers have extensively studied the experiences and potential consequences of being a child whose parent has a mental illness (COPMI). However, there is no consensus on the best way to support these children, in general or in schools. The purpose of this quantitative study was to examine the effects of parental mental illness on children by using an ecological approach. Researchers have used ecological theory to illustrate the importance of internal characteristics, skills, and supports for children to enhance resiliency. This study looked at whether COPMI differed significantly from the children of parents of parents with no current or past …
