Observing Object Lifting Errors Modulates Cortico-Spinal Excitability And Improves Object Lifting Performance., Gavin Buckingham, Jeremy D Wong, Minnie Tang, Paul L Gribble, Melvyn A Goodale

Brain and Mind Institute Researchers' Publications

Observing the actions of others has been shown to modulate cortico-spinal excitability and affect behaviour. However, the sensorimotor consequences of observing errors are not well understood. Here, participants watched actors lift identically weighted large and small cubes which typically elicit expectation-based fingertip force errors. One group of participants observed the standard overestimation and underestimation-style errors that characterise early lifts with these cubes (Error video--EV). Another group watched the same actors performing the well-adapted error-free lifts that characterise later, well-practiced lifts with these cubes (No error video--NEV). We then examined actual object lifting performance in the subjects who watched the EV …

Sign Language Ability In Young Deaf Signers Predicts Comprehension Of Written Sentences In English., Kathy N Andrew, Jennifer Hoshooley, Marc F Joanisse

Brain and Mind Institute Researchers' Publications

We investigated the robust correlation between American Sign Language (ASL) and English reading ability in 51 young deaf signers ages 7;3 to 19;0. Signers were divided into 'skilled' and 'less-skilled' signer groups based on their performance on three measures of ASL. We next assessed reading comprehension of four English sentence structures (actives, passives, pronouns, reflexive pronouns) using a sentence-to-picture-matching task. Of interest was the extent to which ASL proficiency provided a foundation for lexical and syntactic processes of English. Skilled signers outperformed less-skilled signers overall. Error analyses further indicated greater single-word recognition difficulties in less-skilled signers marked by a higher …

Links Between White Matter Microstructure And Cortisol Reactivity To Stress In Early Childhood: Evidence For Moderation By Parenting., Haroon I Sheikh, Marc F Joanisse, Sarah M Mackrell, Katie R Kryski, Heather J Smith, Shiva M Singh, Elizabeth P Hayden

Brain and Mind Institute Researchers' Publications

Activity of the hypothalamic-pituitary-adrenal axis (measured via cortisol reactivity) may be a biological marker of risk for depression and anxiety, possibly even early in development. However, the structural neural correlates of early cortisol reactivity are not well known, although these would potentially inform broader models of mechanisms of risk, especially if the early environment further shapes these relationships. Therefore, we examined links between white matter architecture and young girls' cortisol reactivity and whether early caregiving moderated these links. We recruited 45 6-year-old girls based on whether they had previously shown high or low cortisol reactivity to a stress task at …

Sensitivity Of Human Auditory Cortex To Rapid Frequency Modulation Revealed By Multivariate Representational Similarity Analysis., Marc F Joanisse, Diedre D Desouza

Brain and Mind Institute Researchers' Publications

Functional Magnetic Resonance Imaging (fMRI) was used to investigate the extent, magnitude, and pattern of brain activity in response to rapid frequency-modulated sounds. We examined this by manipulating the direction (rise vs. fall) and the rate (fast vs. slow) of the apparent pitch of iterated rippled noise (IRN) bursts. Acoustic parameters were selected to capture features used in phoneme contrasts, however the stimuli themselves were not perceived as speech per se. Participants were scanned as they passively listened to sounds in an event-related paradigm. Univariate analyses revealed a greater level and extent of activation in bilateral auditory cortex in response …

Dopaminergic Medication Impairs Feedback-Based Stimulus-Response Learning But Not Response Selection In Parkinson's Disease., Andrew Vo, Nole M Hiebert, Ken N Seergobin, Stephanie Solcz, Allison Partridge, Penny A Macdonald

Brain and Mind Institute Researchers' Publications

Cognitive dysfunction is a feature of Parkinson's Disease (PD). Some cognitive functions are impaired by dopaminergic medications prescribed to address the movement symptoms that typify PD. Learning appears to be the cognitive function most frequently worsened by dopaminergic therapy. However, this result could reflect either impairments in learning (i.e., acquisition of associations among stimuli, responses, and outcomes) or deficits in performance based on learning (e.g., selecting responses). We sought to clarify the specific effects of dopaminergic medication on (a) stimulus-response association learning from outcome feedback and (b) response selection based on learning, in PD. We tested 28 PD patients on …

Rule-Based Category Learning In Children: The Role Of Age And Executive Functioning., Rahel Rabi, John Paul Minda

Brain and Mind Institute Researchers' Publications

Rule-based category learning was examined in 4-11 year-olds and adults. Participants were asked to learn a set of novel perceptual categories in a classification learning task. Categorization performance improved with age, with younger children showing the strongest rule-based deficit relative to older children and adults. Model-based analyses provided insight regarding the type of strategy being used to solve the categorization task, demonstrating that the use of the task appropriate strategy increased with age. When children and adults who identified the correct categorization rule were compared, the performance deficit was no longer evident. Executive functions were also measured. While both working …

Organizational Climate And The Theory Of Human Caring In Hospitals, Vivienne C. Meanger

2010-2016 Archived Posters

Patient care in hospitals has become perfunctory, task focused, and void of a personalized human connection, which has become an area of concern among scholars since the 1970s. This experimental, post-test only, control-group study with a purposive patient and clinical staff sample explored the relationship between human caring and patient satisfaction; and the role of leadership in transforming the organizational culture in an long term acute care hospital (LTACH) setting implanting the Magnet initiatives.

Stress: The Development And Influence On Self-Identity, Earl Grey

2010-2016 Archived Posters

Using a grounded theory methodology and constantcomparative analysis, the investigator sought to develop an empirical understanding of the experience of stress and its influence on identity development. The 23 participants, who did not meet criteria for a DSM-IV-TR diagnoses, received 10 - 60 minutes sessions of eye movement desensitization and reprocessing treatment (EMDR). EMDR treatment targets stressful memories and elicits recall of thoughts, imagery, emotions, and physical body sensations related to the stressful experience. The data from video recorded sessions provided holistic information regarding each participant’s experience and recall of stressful events. The results yielded thematic developmental patterns of thoughts, …

The Human-Animal Bond And Combat-Related Posttraumatic Stress, Melissa White

2010-2016 Archived Posters

This study explored the lived experiences of Operational Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) service members with combatrelated posttraumatic stress disorder (PTSD) symptoms who had a companion animal postdeployment. Twelve OEF and OIF veterans participated in semi-structured interviews analyzed using Moustakas’ phenomenological approach. Four themes emerged: (a) rich descriptions of deployment events, (b) the experiences of returning from a deployment, (c) participants’ perceptions on their pets’ influence on posttraumatic stress symptoms, and (d) other comments and opinions related to participants’ experiences. These findings illuminate the experience of combat-related posttraumatic stress and the importance of animals in the therapeutic …

Confidentiality And Mental Health/Chaplaincy Collaboration, Denise Bulling, Mark Dekraai, Tarik Abdel-Monem, Jason A. Nieuwsma, William C. Cantrell, Keith Ethridge, Keith Meador

University of Nebraska Public Policy Center: Publications

Confidentiality can both facilitate and inhibit working relationships of chaplains and mental health professionals addressing the needs of service members and veterans in the United States. Researchers conducted this study to examine opportunities for improving integration of care within the Department of Defense (DoD) and Department of Veterans Affairs (VA). Interviews were conducted with 198 chaplains and 201 mental health professionals in 33 DoD and VA facilities. Using a blended qualitative research approach, researchers identified several themes from the interviews, including recognition that integration can improve services; chaplaincy confidentiality can facilitate help seeking behavior; and mental health and chaplain confidentiality …

The Relationship Between Collective Action And Well-Being And Its Moderators: Pervasiveness Of Discrimination And Dimensions Of Action, Mindi D. Foster

Psychology Faculty Publications

Given the negative impact of perceiving gender discrimination on health (e.g., Pascoe & Smart Richman, 2009), there is a need to develop interventions to attenuate this effect; collective action may be one such intervention. Study 1 (N = 185) used an experimental paradigm to investigate whether undergraduate women in Waterloo, Ontario, Canada perceived pervasiveness of discrimination would interact with their collective action-taking to predict negative mood and well-being. Results showed that among those perceiving pervasive gender discrimination, informing friends/family and informing the media led to greater well-being than doing nothing, whereas among those perceiving gender discrimination as isolated, doing nothing …

Is Burnout A Depressive Disorder? A Reexamination With Special Focus On Atypical Depression, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

Whether burnout and depression cover the same psychopathology remains to be elucidated. To date, subtypes of depression have been overlooked in research on the burnout–depression overlap. Our aim was to estimate the prevalence of depressive disorders in workers with burnout while examining the overlap of burnout with the atypical subtype of depression. The present study included 5,575 schoolteachers (mean age = 41 years; 78% female). Burnout was assessed with the Maslach Burnout Inventory. Depression was measured with the 9-item depression scale of the Patient Health Questionnaire (PHQ-9). Atypical features of depression were examined using a dedicated module, referenced to …

Empathy As A Moderator Of Adolescent Bullying Behavior And Moral Disengagement After Controlling For Social Desirability, Amy Zelidman

Wayne State University Dissertations

The purpose of this study was to assess the moderating influence empathy has on the associations between adolescent bullying behavior and moral disengagement after controlling for social desirability (e.g., response bias). 676 students in 7th and 8th grade from a suburban middle school in Southeast Michigan participated in this study in the fall of 2012.

Results showed male respondents were more likely than female respondents to (a) report engaging in all forms of traditional bullying behavior overall, including physical, verbal, and social bullying and (b) report higher rates of physical victimization and moral disengagement. Female respondents were more likely to …

Accumulation Of Subcortical Iron As A Modifier Of Volumetric And Cognitive Decline In Healthy Aging: Two Longitudinal Studies, Ana Marie Daugherty

Wayne State University Dissertations

Accumulation of non-heme iron in the brain has been theorized as a cellular mechanism underlying global neural and cognitive decline in normal aging and neurodegenerative disease. Relatively few studies of brain iron in normal aging exist and extant studies are almost exclusively cross-sectional. Here, I estimated iron content via T2* and measured volumes in several brain regions in two independent samples of healthy adults. The first sample (N = 89) was measured twice with a two-year delay; and the second sample (N = 32) was assessed four times over a span of 7 years. Latent models estimated change in iron …

Coping Similarity And Psychosocial Risk Factors In Couples With Chronic Pain, Amy M. Williams

Wayne State University Dissertations

Chronic pain is an important public health problem that is associated with a host of negative individual and relationship outcomes. Chronic pain is a chronic stressor that both the individual in pain and their spouse must cope with. The current study examined how pain coping similarity within the couple predicted not only patient adjustment, but also spouse adjustment in a longitudinal study. Participants were 108 heterosexual couples in which one partner had chronic pain. The participants completed measures at 3 time points at 6 month intervals. Both the patient and spouse individually completed questionnaires pertaining to their marriage, mood, pain …

Coming Out, Coming Together, Coming Around: An Interpretative Phenomenological Analysis Of Families' Experiences Adjusting To A Young Family Member's Disclosure Of Non-Heterosexuality, Denise M. Fournier Rodriguez

Department of Family Therapy Dissertations and Applied Clinical Projects

Young people who identify as lesbian, gay, or bisexual (LGB) are disclosing their sexual identity--or coming out--at progressively younger ages, making it more important than ever for the general population to understand, tolerate, and accept diversity in sexual identity. This study was designed to fill the gap in the existing literature about how the coming out process affects LGB young people's families of origin. Three LGB young people participated in the study, along with a member of each of their families. The researcher conducted semi-structured interviews with each of the participants, as well as a conjoint interview with each of …

Living With Uncertainty: The Impact On Breast Cancer Survivors And Their Intimate Partners, Kimberley Dockery

Department of Family Therapy Dissertations and Applied Clinical Projects

This study explored the lived experiences of breast cancer survivors and their intimate partners. The research was informed by a social constructionist framework and phenomenological method of inquiry. While the body of literature on the physical, psychological, and social health of breast cancer survivors is growing, only a few studies have focused solely on the lived experience of survivorship and the uncertainty of recurrence. This study sought to explore the construction of meaning in the couples' context and experiences of surviving breast cancer. The present study examined how breast cancer survivors make meaning of their survivorship in context of living …

The Effects Of Holistic Coping Strategies On Perceived Stress And Absenteeism In Hospital Nurses, Mary Alice Ayon

Walden Dissertations and Doctoral Studies

The demanding work environments of professional nurses often contribute to high levels of stress that impact their professional practice and well-being. Although there is a significant amount of research regarding stress and absenteeism, a gap in the literature exists about the effects of holistic coping strategies on nurses' perceived stress and absenteeism. Based on the biopsychosocial model, the purpose of this quantitative study was to investigate effects of holistic coping strategies on perceived stress and absenteeism in 128 hospital nurses. An online cross-sectional survey design used the Perceived Stress Scale-10 to measure nurses' perceptions of stress. The independent grouping variable …

Grounded Labels From The Behavioral International Economic Development Growth Path Model On Economic Development Patterns From 2002-2012, Kenneth Thomas Davis

Walden Dissertations and Doctoral Studies

Economic models generally fail to adequately measure positive and negative growth paths in development through agrarian, industry, and service economies. The purpose of this grounded theory study was to design a new model that could accommodate both directions of growth and better measure development paths with particular attention to labors contributions. The theoretical foundation for this study was Walt Whitman Rostow's 5 economic stages of growth classifications. This Study attempted to find the most common economic growth path. While most development models use three to five classifications, this study used nine new classifications giving it a unique and specific look …

Injured Athletes' Preferences Regarding Source Of Emotional Support, Kristin Kutz

Honors Projects

Athletes often experience emotional distress as a result of an injury. Feelings of loss, decreased self-esteem, frustration, and anger are not uncommon. Athletic trainers (ATs) who work with injured athletes are focused on helping the progression of athletes' physical healing, but their role in helping athletes emotionally and psychologically is often unclear. There are twelve Athletic Training Education Competencies that the National Athletic Training Association requires to be taught to undergraduate AT students, one of them being psychosocial intervention and referral. However, little research has been done to define the exact role of ATs in this area, as well as …

Longitudinal Change In Regional Cortices And Fluid Intelligence, Peng Yuan

Wayne State University Dissertations

Fluid intelligence (Gf) and crystalized intelligence (Gc) are two factors of the general intelligence. They have distinct age-related trajectories of change. Jung and Haier proposed Parieto-Frontal Integration Theory (P-FIT, 2007) to account for the inter-person variance in reasoning intelligence. Some brain regions such as prefrontal, parietal, temporal and anterior cingulate cortices were included in the P-FIT model and were hypothesized to be involved in fluid reasoning task. Therefore, in the current study, we examined latent growth curves (LGC) of longitudinal change in Gf, Gc, prefrontal cortex, parietal cortex, anterior cingulate, temporal cortex and primary visual cortex. Forty-six healthy middle-aged and …

Self-Efficacy, Self-Determination, And Self-Regulation: The Role Of The Fitness Professional In Social Change Agency, Joshua M. Garrin

Journal of Sustainable Social Impact

Current epidemiological data reported by governing health authorities reveal the biopsychosocial complexity of health maintenance in the 21st century. As statistics reflect the insidious, worldwide impact of chronic disease and psychosocial stress, the medical domain continues to endorse multidisciplinary approaches to support the myriad systems that underpin health and well-being. With their scope of practice continually expanding to accommodate such needs, fitness professionals (FPs) have become a mainstay on the front lines of health behavior management in recent years. Beyond their role in facilitating physical health gains, contemporary FPs undertake the challenge of instilling health self-efficacy beliefs, reinforcing autonomy and …

African American Families' Expectations And Intentions For Mental Health Services, Cynthia J. Najdowski, Richard Thompson, Barbara L. Dancy, Tisha R. A. Wiley, Sylvia P. Perry, Jason Wallis, Yara Mekawi, Kathleen Knafl

Psychology Faculty Scholarship

A cross-sectional qualitative descriptive design was used to examine the links among expectations about, experiences with, and intentions toward mental health services. Individual face-to-face interviews were conducted with a purposive sample of 32 African American youth/mothers dyads. Content analysis revealed that positive expectations were linked to positive experiences and intentions, that negative expectations were not consistently linked to negative experiences or intentions, nor were ambivalent expectations linked to ambivalent experiences or intentions. Youth were concerned about privacy breeches and mothers about the harmfulness of psychotropic medication. Addressing these concerns may promote African Americans’ engagement in mental health services.

Same-Sex Couples' Lived Experiences Of The Repeal Of The Defense Of Marriage Act's (Doma) Section Three, Alicia Anne Bosley

Department of Family Therapy Dissertations and Applied Clinical Projects

Same-sex couples are affected by the social and political climates in which they live, as these create the difference between acceptance and legalization, and discrimination and prohibition, of their relationships. This contingence is made increasingly impactful by the privileges and protections afforded to married couples by the federal government; same-sex couples, along with other couples that choose not to, or cannot, marry, are excluded from these benefits. Following the June 26, 2013 ruling that Section Three of the Defense of Marriage Act (DOMA), which defined marriage as between a man and a woman, was unconstitutional, same-sex couples were given access …

Effects Of Parental Alcoholism And Trauma Exposure On Depressive Symptoms: A Path Model With Resilience, Social Support, And Family Satisfaction, Erin Doty Kurtz

Psychology Theses & Dissertations

The goal of this study was to explore the different effects of parental alcoholism and history of trauma exposure on depressive symptoms in an emerging adult, college population. In particular, mediating effects of resilience, social support, and family satisfaction were evaluated for both parental alcoholism and previous interpersonal trauma exposure using structural equation modeling (SEM). Participants were 708 students (217 male, 491 female) attending a large mid-Atlantic state university. It was . anticipated that social support and family satisfaction would be key mediators between parental alcoholism and depressive symptoms, while resilience and social support would be significant mediators between interpersonal …

Differences In Mental Health Treatment Recommendations For Older And Younger Adults, Michelle M. Smith

Masters Theses

Failure to meet geriatric mental health needs is increasingly problematic. Research indicates that the problem is not simply a matter of insufficient numbers of mental health practitioners (MHPs), but also ageist attitudes and lack of knowledge about and training with older adults. The current study reviews the literature regarding knowledge about older people, education and training that mental health professionals receive, and the attitudes that are held by mental health professionals. The study also assessed for differences in treatment recommendations that MHP made for older versus younger clients, investigated whether MHP knowledge about the mental health of older adults, attitudes …

Relationships Between Breastfeeding, Maternal Cigarette Smoking During Pregnancy, And The Cognitive Functioning Of Akwesasne Mohawk Adolescents Exposed To Environmental Pollution, Georgia Brooke

Legacy Theses & Dissertations (2009 - 2024)

Previous research has suggested that breastfeeding is beneficial for children's health and that maternal cigarette smoking during pregnancy is harmful for children's health. However, there is not a consensus in the existing literature about whether or not these two maternal behaviors impact the cognitive development of children. Furthermore, understanding the role of breastfeeding in children's development is complicated by the fact that breastfeeding transmits toxicants that are stored in the mother's body, including polychlorinated biphenyls (PCBs), to the infant. Existing research suggests that PCBs negatively impact children's cognitive functioning. The current study examined relationships between breastfeeding, maternal cigarette smoking during …

The Effect Of Gaba A Antagonism On Locomotor Activity And Dopamine Release In The Mouse Caudate Putamen Following Acute Toluene Inhalation: An In-Vivo Microdialysis Study, Sean Callan

Wayne State University Theses

Toluene is ubiquitous solvent commonly inhaled recreationally. Despite its frequency of misuse, there is little understanding of how toluene acts within the brain. To examine this, this master's thesis examined the impact of acutely inhaled toluene on dopamine (DA) release in the mouse CPu in vivo using microdialysis techniques. Toluene inhalation produced dose-dependent increases in DA levels as well as changes in locomotor activity. These effects were potentiated by pre-treatment with the GABAA antagonist bicuculline via reverse microdialysis delivery. These results suggest that the DA dynamics of toluene abuse are related to toluene's previously explored effects on the GABA system. …

Inattention And Hyperactivity Among Preschool Age Children Born Prematurely, Andrew Heitzer

Wayne State University Theses

A large body of literature shows that compared to children born at term, preterm- children are at increased risk for difficulties with inattention and hyperactivity. Less consistency exists, however, in the limited body of research exploring the contribution of early biological risk to behavioral disinhibition within the population of children born prematurely. Therefore, our goal was to examine perinatal variables that may influence activity level and hyperactivity among preterm preschoolers. Ninety-eight preterm (23.4 - 33.9 weeks gestation) preschoolers (3-4 years) participated in the study. Direct measures of inattention and hyperactivity as well as parental ratings were used to evaluate behavior. …

A Mother's Paradox: Choosing A Birthing Method In The 21st Century, Jenae Franklin

Pitzer Senior Theses

Investigating childbirth, one of the biggest moments of a woman’s life, this thesis examines the reasons behind women’s preferred birthing methods. This research explores the fundamental decisions women make during the birthing process: the amount of prenatal care mothers will receive, the type of health care provider they will use, picking the place of delivery, views on technological and medical interventions, and outlooks on natural childbirth. In addition to an extensive literature review, in-depth interviews with mothers, midwives, and obstetricians are used to examine the various controversies of childbirth. This thesis begins with a review of the transition from midwives …
