A Single Strand Of Argument With Unfounded Conclusion, Robert W. Elwood

Animal Sentience

Key (2016) describes the neural system involved in human pain experience in an excellent fashion but then suggests that only that complete system can generate the experience of pain. Thus animals without all components will not feel pain. This argument has been refuted in the past by analogy to vision where it is clear that a broad range of taxa, vertebrate and invertebrate, have good visual abilities albeit with completely different central nervous systems and receptors. This known counterargument to Key’s main idea is not mentioned in the target article. Further criteria that might indicate pain and studies examining these …

What Would The Babel Fish Say?, Monica Gagliano

Animal Sentience

Starting with its title, Key’s (2016) target article advocates the view that fish do not feel pain. The author describes the neuroanatomical, physiological and behavioural conditions involved in the experience of pain in humans and rodents and confidently applies analogical arguments as though they were established facts in support of the negative conclusion about the inability of fish to feel pain. The logical reasoning, unfortunately, becomes somewhat incoherent, with the arbitrary application of the designated human criteria for an analogical argument to one animal species (e.g., rodents) but not another (fish). Research findings are reported selectively, and questionable interpretations are …

Cognitive And Behavioral Mechanisms Underlying Alcohol-Induced Risky Driving, Jennifer R. Laude

Theses and Dissertations--Psychology

Alcohol intoxication represents one situation an individual might increase their amount of risk taking when driving. This dissertation is comprised of three studies that investigate the mechanisms by which alcohol increases driver risk-taking. Study 1 examined the effect of alcohol on driver risk-taking using a proxemics approach. The study also tested whether alcohol-induced increases in risky driving co-occurred with pronounced impairment in the driver’s skill. The study also examined whether the most disinhibited drivers were also the riskiest. Indeed, alcohol increased driver risk-taking and impaired driving skill. The study also revealed risky driving can be dissociable from impairing effects on …

Relationship Between Meaning In Life And Dispositional Forgiveness, Shirley Karseboom

Walden Dissertations and Doctoral Studies

Both meaning in life and forgiveness have been shown to separately contribute to better mental health. However, no prior research examined the linkage between meaning in life and forgiveness. This quantitative study was therefore to identify if there was a relationship between meaning in life, as measured by the Meaning in Life Questionnaire (MLQ), and overall dispositional forgiveness, dispositional forgiveness of self, dispositional forgiveness of others, and dispositional forgiveness of situations, as measured by the Heartland Forgiveness Scale (HFS). Survey data were gathered from 250 college students in Western Canada, and multiple linear regression controlling for sociodemographic factors was used. …

Psychological Capital As A Mediator Between Team Cohesion And Productivity, Robert John Cesaro

Walden Dissertations and Doctoral Studies

Organizations attempting to optimize productivity are seeking new ways to develop psychological capital in teams. The researcher conducted a quantitative study to determine whether team cohesion, as assessed by the Revised Group Environment Questionnaire (RGEQ), impacts team productivity, as assessed by the Performance Measurement Team (PMT) Manufacturing Resource System (MRS); whether this relationship can be attributed to a team's level of psychological capital, as assessed by the Psychological Capital Questionnaire (PCQ-12); and whether psychological capital mediates the relationship between team cohesion and team productivity. Forty-five PMTs in a large U.S. defense manufacturing organization were surveyed using the PCQ-12 and the …

Our Critics Might Have Valid Concerns: Reducing Our Propensity To Conflate, Carolyn Becker

Psychology Faculty Research

As noted by Austin elsewhere in this issue, the field of eating disorders (ED) prevention has made remarkable scientific strides in the past two decades (see Austin, 2016). Over this same period, the field also has seen improved political standing within the greater ED community. For instance, prevention researchers present more regularly at key ED conferences, increasingly via invitation “up on the big stage” in plenaries and keynote addresses. Prevention researchers and advocates also appear to have grown in number and hold more positions in a variety of ranks throughout key ED organizations. Finally, a number of prominent ED researchers …

Cross-Language Conceptual Activation And Development Through Text Passages, Karly Meillyn Schleicher

Open Access Theses & Dissertations

The present study begins to bridge the gap between bilingual education practices and cognitive frameworks of bilingual conceptual access. A reading comprehension task was used to investigate how bilingual undergraduate students activate and develop academic information across their two languages when reading expository text. Using scientific texts, participants (N = 128) read two distinct passages pertaining to prior knowledge, as well as new, related conceptual information. At test, the participants were asked to complete true-false questions and elaborate on the reasons for their responses. A counterbalanced, mixed factorial design was used to infer how language dominance influences encoding and retrieval …

A Phenomenological Study Of East African Refugee Mothers' Experiences Of Trauma And How It Affects Parenting, Binh Hoa Pham

Antioch University Dissertations & Theses

There is a growing population of refugees around the world. Refugees experience a multitude of stressors—war trauma, chaotic and unsettling displacement(s), and resettlement stressors. African and Middle Eastern refugees are the fastest growing refugee population. The Office of the United Nations High Commissioner of Refugees (2014) report estimates that by the end of 2014, there will be 59.5 million displaced people around the world. Refugee women and children are disproportionately victims of war and civil conflict. Research on the experience of refugee women and children is minimal in refugee studies, specifically how refugee mothers’ experiences of war affect parenting. The …

An Analysis Of Psychologist Postdoctoral Psychopharmacology Training Materials For Critiques Of Neurobiological Hypotheses Of Depression's Etiology, Critical Analyses Of The Dsm's Rigor, And For Consumer/Survivor/Ex-Patient Content., Chris William Nicholas Rowe

Antioch University Dissertations & Theses

There is widespread agreement that neurobiology plays a role in psychological distress and that psychiatric diagnosis and associated psychopharmacological interventions can be helpful. However, there are also unresolved issues surrounding the limits of empirical support for current diagnostic criteria, shortcomings in neurobiological explanations of psychopathology, and unanswered questions about the mechanism, safety, and efficacy of psychiatric medications. This has implications for treatment errors which can precipitate negative socio-economic and health consequences, particularly for vulnerable groups like the Consumer/Survivor/Ex-Patient (c/s/x) population. It is for these reasons that the training psychologists receive to prescribe should, in addition to integrating the critiques of …

Bind, Tether, And Transcend: Achieving Integration Through Extra-Therapeutic Dance, Megan M. Kain

Antioch University Dissertations & Theses

The purpose of this study is to examine the lived experience of achieving integration through the fine art form of dance, using a phenomenological method coupled with narrative and arts-based research. Research material illustrating the various manifestations of integration will be derived from interviews of ten professional dancers representing the non-dominant cultural discourse. Through the application of theoretical underpinnings of somatic psychology, interpersonal neurobiology, psychoneuroimmunology, and relational psychotherapy, this qualitative research seeks to articulate the esoteric healing forces derived from creative movement that fortifies self and fosters resilience within individuals. While dance might constitute an effective processing and coping mechanism …

Frequencies Between Serial Killer Typology And Theorized Etiological Factors., Leryn R. Messori

Antioch University Dissertations & Theses

This study examined the association between serial killer typologies and previously proposed etiological factors within serial killer case histories. Stratified sampling based on race and gender was used to identify thirty-six serial killers for this study. The percentage of serial killers within each race and gender category included in the study was taken from current serial killer demographic statistics between 1950 and 2010. Detailed data was gathered about each case, including past experiences and details of their crimes using publicly available primary and secondary source material. Etiological factors identified for this study include military experience, alcohol use, drug use, whether …

The Stress-Buffering Model Of Social Support In Post-Acute Brain Injury Rehabilitation, Emily Anna Pearce

Antioch University Dissertations & Theses

Currently, 3.2-5.3 million Americans (1.1-1.7%) live with long-term disability resulting from acquired brain injury (ABI). Despite two to three million more being treated yearly for milder injuries and released without further services, those with enduring problems often require ongoing rehabilitation and support. The immediate and long-term costs of ABI are substantial, as are the burdens associated with lifelong sequelae. A clear understanding of prognostic indicators—only some of which have been identified—could assist in reducing these costs and burdens. Social support, which has been linked with physical health and function in populations across the world, is one likely indicator. Family stress, …

The Relationship Between Resilience And Academic Success Among Bermuda Foster Care Adolescents, Zina Denise Zuill

Walden Dissertations and Doctoral Studies

The primary goal of this study was to explore whether individual resiliency factors measured by the Resilience Scale (RS) influence academic success for Bermudian foster care adolescents, a population previously unstudied in the literature. Academic vulnerability is a concern for foster care adolescents, and more empirical studies need to be conducted to increase understanding of the variables that affect academic success for this population. Resiliency is a conceptual framework based on a positive developmental focus. The purpose of this study was to gain insight into the relationship between resilience and academic success among 51 Bermudian foster care adolescents who attended …

The Predictive Relationship Between Emotional Expressiveness And Discussing Death With Children: An Exploratory Study With Online College Parents, Sally A. Gill

Walden Dissertations and Doctoral Studies

Death is a sensitive topic, and discussing death with children may be difficult for parents, especially parents who are uncomfortable with emotional expression. Many factors are associated with parents' decision to discuss death; however, a dearth of recent literature existed examining the role of parental emotional expressiveness and discussing death with children. Using Jackson's communications theory within the broader family systems theory, this exploratory non-experimental quantitative study examined if one or more of the selected variables of parents' emotional expressiveness, parents' gender, and any previous discussions about death with a child adequately predicted the age of a child when parents …

Empathy In Detained Male Juvenile Offenders, Cloyce Joe Barton

Walden Dissertations and Doctoral Studies

In Texas and across the United States, minority male juvenile offenders are overrepresented in juvenile detention facilities. Researchers have demonstrated an inverse relationship between levels of empathy and antisocial beliefs and delinquent behaviors in juveniles. Understanding this relationship is an important step in designing and implementing rehabilitative interventions for juvenile detainees. Grounded in social learning theory and the social empathy model, the current study addressed whether significant differences in empathy existed between nonminority and minority male juvenile offenders with felony and nonfelony offenses within a juvenile detention facility in rural Texas. A de-identified data set of 357 Interpersonal Reactivity Index …

The Role Of Religiosity In The Development Of Obesity From Adolescence To Adulthood, Trini Gene Rangel

Walden Dissertations and Doctoral Studies

The development of obesity from adolescence to adulthood is not well understood, nor does the research support a multidimensional approach for this understanding. Studies have described primarily cross-sectional bivariate relationships between combinations of obesity, religiosity, depression, and social support, but it is still not known whether there is a relationship between adolescent religiosity, depression, and social support in the development of adult obesity or whether depression and social support mediate the religiosity-obesity relationship. The dynamic, multidimensional, functional model of wellness presented by Hawks was the basis for the spiritual, social, emotional, and physical interactions proposed in this study. The research …

The Relationship Between Stress, Coping Strategies, And Social Support Among Single Mothers, Nikitra Yvette Williams

Walden Dissertations and Doctoral Studies

Researchers have neglected to focus on understanding the relationships between stress, coping, and social support among single mothers versus mothers who are not single. Knowledge regarding how single mothers' lives are affected by stress, social support, and coping is important, and such information can help readers better understand how effectively single mothers raise children compared with mothers who are not single. A convenience sample of 173 mothers completed this study. Participants in this study consisted of mothers who were (a) raising at least one child ages 18 and under who lives in the home and (b) who were between the …

Children Of Holocaust Survivors On Middle-Age: A Phenomenological Inquiry, Elizabeth Rosenberg

Walden Dissertations and Doctoral Studies

Children of Holocaust survivors are vulnerable to experiencing secondary trauma which typically manifests in emotional and psychological difficulties. Despite,their exposure to a traumatized family environment, many children of Holocaust survivors do not develop emotional or adaptive difficulties. Some demonstrate psychological resilience, reflected by their ability to adapt,to adversity and problems. The purpose of this study was to gain insight into how well-adjusted,middle aged children of Holocaust survivors developed and maintained resilience.In line with resilience theory,which explains how an individual bounces back from negative circumstances, the research questions for this study examined the factors that the participants used to develop and …

Utilization And Intensity Of Integrated Behavioral Health Services Within A Primary Care Setting, Joseph Aron Shafer

Walden Dissertations and Doctoral Studies

Integrated behavioral health care within primary care has become a popular style of health care delivery within the United States. However, individuals with a behavioral health concern face several barriers in using these services. The purpose of this quantitative study was to identify key factors accounting for individuals' utilization and intensity of behavioral health services. Andersen's behavioral model of health care use and the integrated theory of health behavior change served as the theoretical framework. It was hypothesized that gender, age, race, ethnicity, family size, payer type, poverty level, and certain preexisting medical conditions (obesity, diabetes, hypertension, and tobacco use) …

The Relationship Between Nutrient Intake And Social Emotional Functioning In Preschool Children, Tracy L. Daniel

Walden Dissertations and Doctoral Studies

Mental health disorders are rising in children and being referred to as an epidemic. Numerous studies have shown micronutrient deficiencies and poor diet quality are suspected of playing a contributory role in the escalation of certain disorders. However, there is no research in young children focusing specifically on social emotional disorders and possible links to nutrition. Conventional treatment for social emotional disorders in children typically involves medication. Parents are increasingly turning to complementary and alternative medicine to treat their children with a method that is individualized and holistic. The biopsychosocial model provided the theoretical framework for this correlational study that …

Categorical Perception Of Species In Infancy, Hannah B. White

Theses and Dissertations--Psychology

Although there is a wealth of knowledge on categorization in infancy, there are still many unanswered questions about the nature of category representation in infancy. For example, it is yet unclear whether categories in infancy have well-defined boundaries or what knowledge about species categories young infants have before entering the lab. Using a morphing technique, we linearly altered the proportion of cat versus dog in images and observed how infants reacted to contrasts between pairs of images that either did or did not cross over the categorical boundary. This was done while equating between-category and within-category similarity. Results indicate that …

Investigating The Role Of Social Support, Cardiovascular Reactivity, And Self-Regulation Skills Training In Response To Thermal Stimuli, Tracey Christine Kniffin

Theses and Dissertations--Psychology

Persistent pain conditions are a major health problem throughout the world and are one of the primary reasons that people seek medical treatment (Gureje, Von Korff, Simon, & Gater, 1998; Verhaak, Kerssens, Dekker, Sorbi, & Bensing, 1998). These conditions are characterized by complex interactions between cognitive, emotional, and physiological disturbances and are often associated with comorbid psychological disorders (Gatchel, 2004). Though previous studies have examined the effect of interventions targeting persistent pain, such as physical self-regulation interventions, few studies have examined the complex interaction between such interventions and other variables such as psychological and physiological …

Validity Of Immediate Post-Concussion Assessment And Cognitive Testing (Impact), Lisa Mason Koehl

Theses and Dissertations--Psychology

Sports concussions have been recognized as significant injuries among young athletes with research demonstrating that return-to-play prior to becoming asymptomatic can have significant repercussions, including risk of sustaining cognitive deficits. In tracking and monitoring concussions during sports seasons, many programs have begun utilizing computerized testing rather than traditional neuropsychological tests to 1) determine baseline scores, 2) track symptoms, and 3) measure cognitive deficits following concussion.

Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is one such instrument. The current study examined ImPACT’s convergent, discriminant, and diagnostic validity by comparing scores from post-concussion athletes (SPORT) to those from non-concussed controls (CONT). SPORT …

Trait-Based Profiles Of Adhd In Adolescents And Young Adults, Tess E. Smith

Theses and Dissertations--Psychology

Empirical work has examined the utility of using person-centered statistical approaches emphasizing traits to parsing Attention-Deficit/Hyperactivity disorder (ADHD) heterogeneity in preschool and school-aged children. However, trait-based profiles have not yet been examined in other age ranges, specifically adolescence and young adulthood. Therefore, the goal of the present study is to examine trait-based profiles in adolescents and young adults with ADHD in order to evaluate their similarity with trait-based profiles in preschoolers and children with ADHD and through comparison with external correlates (e.g., comorbidity). One hundred and eighty-two adolescents and 287 young adults completed measures of ADHD symptoms, personality and temperament …

Psychosocial Functioning In Adolescents With Temporomandibular Disorders, Monica L. Gremillion

Theses and Dissertations--Psychology

Psychosocial functioning is a key component of screening and treatment of Temporomandibular Disorders (TMD) in adults; however, psychosocial functioning in adolescents with TMD has received little empirical attention. The present study aims to examine group difference between adolescents and adults with TMD on pain and prominent psychosocial factors, such as anxiety, depression, and somatization, as well as to explore additional developmentally sensitive psychosocial factors that may be associated more with the adolescent TMD pain.

Participants included 35 adolescents aged 12-17 (M=14.89 years, SD=1.84) with TMD muscle pain who completed pain questionnaires and a comprehensive dental examination. Patients …

Loss Aversion In Cocaine Users: Influence Of Risk And Commodity Type, Justin Charles Strickland

Theses and Dissertations--Psychology

Numerous studies in behavioral economics have demonstrated that individuals are more sensitive to the prospect of a loss than a gain (i.e., loss aversion). Although loss aversion has been well described in healthy populations, little research exists in individuals with substance use disorders. The purpose of this study was to comprehensively evaluate loss aversion in cocaine users. Participants completed measures designed to assess loss aversion for drug and non-drug commodities under varying risk conditions. Cocaine demand was determined using a cocaine purchase task. Cocaine users showed a loss aversion score that was consistent across commodity and risk conditions. Compared to …

Ovarian Hormones, Adhd, Risk-Taking, & Impulsivity, Bethan A. Roberts

Theses and Dissertations--Psychology

Attention-Deficit/Hyperactivity Disorder (ADHD) is a highly impairing disorder of inattention, hyperactivity, and impulsivity that is more frequently diagnosed in males versus females at a ratio of 3:1. However, females with the disorder become highly impaired during adolescence, perhaps due to the onset of cycling ovarian hormones at puberty. The present study empirically assessed the role of the major female sex hormones, estrogen and progesterone, in the presentation of ADHD symptoms, impulsivity, and associated risk-taking behaviors (e.g., risky sex, substance use and abuse) in a non-clinical sample of young adult women. 32 healthy young adult women who were screened for hormonal …

Life Adversity, Social Support, Resilience, And College Student Mental Health, Joshua Mello

All Master's Theses

This study investigated how adverse childhood experiences (ACEs), current college student hassles, and perceived social support relate to college student resilience. This study also explored how ACEs, current college student hassles, perceived social support, and resilience relate to college student mental health. A sample of 507 students from a public university in Washington State completed an online study which consisted of surveys operationalizing each variable. The results showed that current college student hassles and perceived social support significantly predicted resilience. Current college student hassles, resilience, and perceived social support also significantly predicted mental health. The study revealed that ACEs had …

Burnout And Depression In Psychiatric Residents, Irvin Sam Schonfeld, Eric Laurent, Pierre Vandel, Renzo Bianchi

Publications and Research

Kealy et al. (2016) found that 21% of psychiatric residents were suffering symptoms of burnout. A number of problems call that finding into question. First, the writers used a one-item measure to assess burnout. Second, mounting evidence suggests that burnout is a depressive syndrome. Third, unresolvable job stress is related to depression. Given burnout's overlap with depression and the diagnostic blur around burnout, research on the impact of job stress should connect with depression, which is nosologically well characterized and diagnosable using clinically validated instruments.

Adhd Symptoms, Social Problems, And Independence In Adolescent And Young Adult Males With Fxs, Marjorie Lee Grefer

Theses and Dissertations

Adolescents and young adults with fragile X syndrome (FXS) typically report a range of comorbid, impairing conditions including cognitive deficits, autism, and attention deficit/hyperactivity disorder (ADHD). Similarly these individuals experience social problems and very low levels of proficiency in independent living, which makes it extremely important to better understand what contributes to these deficits and how to potentially intervene and improve outcomes. Despite this importance, very little attention has been paid to the developmental period of adolescence in the FXS population. In addition, no previous work has utilized specific narrow band measures to probe for ADHD symptoms and instead has …
