Neural Correlates Of The Extreme Male Brain Theory In Adolescents With And Without Autism Spectrum Disorders, Audrey Meyer Carson

Dissertations (1934 -)

The Extreme Male Brain (EMB) theory (Baron-Cohen, 2003) is a behavioral theory of autism spectrum disorders (ASD), suggesting that the triad of behavioral impairments in ASD can be conceptualized psychologically as impairment in empathizing, coupled with a superior capacity for systemizing. Despite studies of the behavioral manifestations of this theory, it lacks neurological findings, specifically evidence of less coordinated activity between the left and right hemisphere in ASD (i.e. more lateralized activity). This study attempted to investigate neural correlates of the EMB theory utilizing EEG coherence, an index of neural connectivity, to determine if a more lateralized profile exists in …

How Counselors Are Trained To Work With Bisexual Clients In Cacrep-Accredited Programs, Laurie Anne Bonjo

Theses and Dissertations in Early Childhood Education

In spite of recent progress toward addressing the need for cultural competence with lesbian and gay-identified clients, bisexual-identified clients continue to be marginalized in the principles, theories, and methods of studying sexuality as well as in the training provided by counselor educators. A descriptive content analysis was conducted to determine what is currently taught about bisexuality and bisexual-identified clients in CACREP-accredited counseling programs. Instructors teaching multicultural counseling in CACREP-accredited programs were asked to provide syllabi, as well as information on textbooks and supplemental materials. Combining constructionism with queer theory and elements of post-positivism, I explore the magnitude to which bisexuality …

Moral Development In The Military: The Efficacy Of Rotc Morality Training At The Sophomore Level, Paul A. Gillett

Doctoral Dissertations and Master's Theses

The Reserve Officers Training Corps (ROTC) is an accessions program designed to produce quality commissioned Officers for operational units, in support of strategic Department of Defense (DoD) objectives. The traditional program length of 4 years coincides with the average number of years required to obtain a baccalaureates degree in the United States, in part because a degree is required for program completion. The program goals are to develop candidates physically, mentally, and morally in order to ensure they can be entrusted with the highest levels of leadership required of a US citizen.

This study aimed at assessing the moral development …

The Effects Of Sensor Performance As Modeled By Signal Detection Theory On The Performance Of Reinforcement Learning In A Target Acquisition Task, Nate Quirion

Doctoral Dissertations and Master's Theses

Unmanned Aerial Systems (UASs) today are fulfilling more roles than ever before. There is a general push to have these systems feature more advanced autonomous capabilities in the near future. To achieve autonomous behavior requires some unique approaches to control and decision making. More advanced versions of these approaches are able to adapt their own behavior and examine their past experiences to increase their future mission performance. To achieve adaptive behavior and decision making capabilities this study used Reinforcement Learning algorithms. In this research the effects of sensor performance, as modeled through Signal Detection Theory (SDT), on the ability of …

The Effectiveness Of A Teen Pregnancy Prevention Program That Offer Special Benefits For Pregnant And Parenting Teens: A Qualitative Study, Marsha Brown

Doctoral Dissertations and Projects

Teen pregnancy continues to be a problem for families, educators, health care professionals, and the government. Teenagers are not afforded the opportunity to learn or receive reinforcement on God's laws on abstaining from premarital sex because religious education is not allowed in the public school system. This increase has led to the creation of the Teenage Parenting Center (TAPP), located in southwest Georgia. TAPP is one of 64 schools in a school district that offers special benefits for pregnant and parenting teens. This qualitative case study used a phenomenological approach to explore the experience of eight former attendees of the …

Conservative Holiness Pastors' Ability To Assess Depression And Their Willingness To Refer To Mental Health Professionals, Andrew Graham

Doctoral Dissertations and Projects

The purpose of this study was to investigate the willingness and ability of Conservative Holiness pastors to assess depression and their willingness to refer to mental health professionals. Eighty-six pastors completed a four-part survey that measured diagnostic accuracy, willingness to refer, attitudes toward mental health, perceived competency to assist, recognition of need for help and confidence in mental health professionals. Demographic characteristics and case study responses were investigated through analysis of frequency data; relationships with demographic variables were analyzed using Spearman's rho and independent t-tests; relationships with variables derived from the scales were analyzed using Pearson Product-Moment Correlation. Analyses found …

A Qualitative Inquiry Into The Treatment Experience Of Adolescent Females In A Relationally Based Therapeutic Boarding School, Douglas S. Marchant

Theses and Dissertations

Individualism, the assumption that persons are self-contained and primarily act for the sake of the self, is prevalent in American culture and has arguably perpetuated numerous psychological and societal ills. Relationality, the assumption that persons are always and inextricably constituted by relationships, has been posited as a philosophical and practical alternative to individualist culture. Several scholars, both inside and outside of psychology, have developed relational concepts and practices, including some who have elucidated a relational approach to psychotherapy (e.g., Slife and Wiggins, 2009). This study examines the implications and effects of this therapeutic approach, particularly exploring relationality's therapeutic success in …

Does Marriage Therapy Improve Health?, David Marsh, Dr. Julianne Holt-Lunstad

Journal of Undergraduate Research

The purpose of this study is to determine the effects of marital quality on certain cardiovascular health risks, including diabetes, blood pressure, and cholesterol levels. Relationships, including that of marriage, have long since been known to correlate with these physiological markers (Wickrama, 1997). Our study, however, is different, as it is the first study to include a marriage therapy intervention. This type of study carries with it more weight than just a correlation study, but obviously brings with it more difficulty. We are in the final stages of gathering data. We have studied more than 210 participants and anticipate being …

Concepts Of Divine Action For A Theistic Approach To Psychology, Brent S. Melling

Theses and Dissertations

Recent years have seen increased interest in using theism (the perspective that assumes that God is currently actively in the world) as a conceptual framework for scientific inquiry. This interest has built particular momentum in psychology where several scholars have expressed that traditional naturalistic approaches limit understanding and investigation of psychology's subject matter and thus are insufficient to fully account for human phenomena. Others have previously made the case for the consideration of theism as a legitimate alternative basis for psychological theory, research, and practice. This dissertation begins with that consideration and examines what would be required to move a …

Biological Markers Of Cognition And Error-Detection, Nicholas Edwards, Dawson Hedges

Journal of Undergraduate Research

The purpose of my project was to find factors that might be predictive of cognitive deficits in a college age group of people. After discussing the topic with my mentor, Dawson Hedges, we chose a few broad categories, including family health history, demographics, education, and psychological history. Once we had decided upon these topics, I began looking through the literature to see what questions people had already asked.

Lesions Of The Intergeniculate Leaflet Lead To A Reorganization In Circadian Regulation And A Reversal In Masking Responses To Photic Stimuli In The Nile Grass Rat, Andrew J. Gall, Laura Smale, Lily Yan, Antonio A. Nunez

Faculty Publications

Light influences the daily patterning of behavior by entraining circadian rhythms and through its acute effects on activity levels (masking). Mechanisms of entrainment are quite similar across species, but masking can be very different. Specifically, in diurnal species, light generally increases locomotor activity (positive masking), and in nocturnal ones, it generally suppresses it (negative masking). The intergeniculate leaflet (IGL), a subdivision of the lateral geniculate complex, receives direct retinal input and is reciprocally connected with the primary circadian clock, the suprachiasmatic nucleus (SCN). Here, we evaluated the influence of the IGL on masking and the circadian system in a diurnal …

Client Experiencing In Cognitive-Behavioral Treatment For Eating Disorders, James William Vandyke

Theses and Dissertations

Depth of client experiencing has been associated with positive therapeutic outcomes across theoretical orientations. Experiencing describes a particular mode of cognitive-affective processing in which clients use internal felt experience as the basis for self-examination and the resolution of personally significant issues. Given evidence that eating disorders are associated with particular disruptions of cognitive-affective processing, it is likely that experiencing plays a role in the successful treatment of eating pathology. However, no study to date has examined the relationship between experiencing and outcome in eating disorder treatment. The purposes of the current study were to examine depth of client experiencing during …

Reflection Of Self: Ageism And The Body, Jasmin Tahmaseb-Mcconatha

Psychology Faculty Publications

Cultural body ideals are often elusive and unattainable, especially with age. Aging bodies can can become a symbol of despair leading to anxiety and unhappiness. We negotiate our identities through our bodies.

Brain Structures Associated With Temperament And Social Behavior In Rhesus Monkeys: An Mri Study, Andrew C. Chaffin

Theses and Dissertations

Temperament is thought to be the foundation for normative personality and subsequent behaviors later in life. To assess the relationship of early temperament with variation in structural brain development, this study examined rhesus macaque mother-infant behavior, and then three years later, used MRI to assess neurostructural differences. Individual differences in mother-infant interactions and emotionality were then linked to brain differences. Extensive behavioral data obtained over the first year of life under both resting and stressful conditions was used to assess the quality of mother-infant interactions and emotionality. The MRI focused on brain volume in areas thought to be related to …

Memory Processes In Pregnant Women, Quentin Smith, Dr. Brock Kirwan

Journal of Undergraduate Research

Pregnancy is a complicated biological process that is often accompanied by reported cognitive changes among pregnant women. Pregnant women commonly report diminished cognitive functioning during pregnancy, with “forgetfulness” and “a poor memory” as the most common complaints (Brett & Baxendale, 2001; Crawley, 2002). However, despite these anecdotally reported deficits, the evidence suggesting memory impairments in pregnancy are equivocal. In a recent meta-analysis of 14 studies of memory in pregnancy, it was concluded that pregnancy disrupts some, but not all, memory processes (J. D. Henry & Rendell, 2007). In particular, memory tasks that place high demands on executive cognitive control seem …

Evaluating A Social And Emotional Learning Curriculum, Strong Kids, Implemented School-Wide, Thomas Jonathan Kramer

Theses and Dissertations

The goal of this study was to explore whether Strong Kids could result in improved social and emotional competence when implemented as a school-wide universal intervention. No prior studies have examined this question. This study also evaluated whether teachers could implement Strong Kids as it was designed and whether they viewed it as socially valid. It used a non-equivalent control group design. The treatment school in the study involved 348 students and 17 teachers from a Title I school. School demographics indicated that 61% of students were Hispanic, 37% White, and 2% of other ethnicities. Approximately 82% of the students …

Law Enforcement And The Mentally Ill: Thirty Years Of Police Literature, Jennifer Noe

Publications and Research

This study applies the methodology of content analysis to 30 years of law-enforcement literature to determine whether online access to scholarly research in social work and mental health made a difference in police policy toward the mentally ill. Keywords from the controlled vocabulary of these fields were found in the body of content analyzed prior to easily accessible online resources in 1997 , yet the number of articles on the subject grew from approximately one per year prior to 1998 to nearly five per year by 2011. The imprint of these two fields from outside of law enforcement was discernible …

Lost In The Margins? Intersections Between Disability And Other Non-Dominant Statuses With Regard To Peer Victimization And Psychosocial Distress Among Oregon Teens, Marjorie Grace Mcgee

Dissertations and Theses

Youth with disabilities experience greater levels of victimization than non-disabled youth. However, little is known about the associations between peer victimization and disability status alone and in combination with sex and race/ethnicity, or with sex and sexual orientation. Further, little is known about the extent to which exposure to peer victimization mediates the relationship between disability status and psychosocial distress. Thus, one purpose of this study was to investigate the extent to which disability status, as a marker of social difference, alone and in combination with other social identities, is associated with differential levels of exposure to peer victimization. A …

Adaptation To The U.S. And Religion/Spirituality: Experiences Of Indian International Students, Kirti Potkar

Theses and Dissertations

Religion and spirituality are deemed an important aspect of human diversity, found to be important to people, and have significant impact on different aspects of functioning. Given the rising numbers of international students on U.S. campuses, it becomes important to examine how religion/spirituality impacts their sojourn in the U.S. This study explored the religious/spiritual experiences of Indian international students here in the U.S. using a qualitative approach. Thirteen Indian international students pursuing graduate degrees in the U.S. were interviewed. The interviews were then transcribed and analyzed using a synthesis of hermeneutic methods informed by Kvale (1996). The following themes emerged …

The Role Of Anxiety In Binge Eating Behavior: A Critical Examination Of Theory And Empirical Literature, Kamila S. White, Diane L. Rosenbaum

Psychology Faculty Works

The purpose of this manuscript is to expand the understanding of binge eating by reviewing the role of aspects of negative affect. Specifically, this paper will present evidence for further investigation of the bearing that anxiety may have in binge eating development and maintenance. A comprehensive review of the literature regarding the relation of binge eating and anxiety was performed. Valuable contributions have been made to the binge eating literature regarding some aspects of negative affect (i.e., depression); however, outside of bulimia nervosa studies, much of the theoretical and empirical binge eating research to date has not directly addressed the …

A Narrative Review Of Yoga And Mindfulness As Complementary Therapies For Addiction., Surbhi Khanna, Jeffrey M Greeson

College of Science & Mathematics Departmental Research

This paper reviews the philosophical origins, current scientific evidence, and clinical promise of yoga and mindfulness as complementary therapies for addiction. Historically, there are eight elements of yoga that, together, comprise ethical principles and practices for living a meaningful, purposeful, moral and self-disciplined life. Traditional yoga practices, including postures and meditation, direct attention toward one's health, while acknowledging the spiritual aspects of one's nature. Mindfulness derives from ancient Buddhist philosophy, and mindfulness meditation practices, such as gentle Hatha yoga and mindful breathing, are increasingly integrated into secular health care settings. Current theoretical models suggest that the skills, insights, and self-awareness …

Rescued Goats At A Sanctuary Display Positive Mood After Former Neglect, Elodie F. Briefer, Alan G. Mcelligott

Sentience Collection

Moods influence cognitive processes in that people in positive moods expect more positive events to occur and less negative ones (“optimistic bias”), whereas the opposite happens for people in negative moods (“pessimistic bias”). The evidence for an effect of mood on cognitive bias is also increasing in animals, suggesting that measures of optimism and pessimism could provide useful indicators of animal welfare. For obvious ethical reasons, serious poor treatments cannot be easily replicated in large mammals in order to study their long-term effects on moods. In this study, we tested the long-term effects (>2 years) of prior poor welfare …

Environmental Change Alters Personality In The Rainbow Trout, Oncorhynchus Mykiss, Ashley J. Frost, Jack S. Thomson, Charlotte Smith, Hannah C. Burton, Ben Davis, Phillip C. Watts, Lynne U. Sneddon

Sentience Collection

Boldness is a personality trait that defines how individuals respond to risky situations and has clear fitness consequences. Since the adaptive value of boldness is context dependent, the benefit of a distinct personality is less clear when the environment is unpredictable. An ability to modulate behaviour can be beneficial, although as behavioural plasticity itself may be costly this depends on the levels of environmental stability. Both boldness and its plasticity are linked with physiological stress coping mechanisms, whereby animals with reduced glucocorticoid responses to stress are bolder and less flexible in behaviour. We investigated the behavioural changes made by bold …

Site Fidelity And Homing Behaviour In Intertidal Fishes, Gemma E. White, Culum Brown

Sentience Collection

The theory of ecological cognition poses that the brains and behaviour of animals are shaped by the environmental challenges they face in their everyday lives. Site fidelity and homing ability was tested for five species of intertidal rock pool fish by tagging and displacing them to new rock pools at various distances from their ‘home’ rock pools. Three of the species were rock pool specialists whilst the remaining two spend a small proportion of their life in rock pools during early ontogeny. The three specialists showed strong site fidelity with >50 % of individuals found in the same pool 42 …

Are Juvenile Domestic Pigs (Sus Scrofa Domestica) Sensitive To The Attentive States Of Humans? The Impact Of Impulsivity On Choice Behaviour, Christian Nawroth, Mirjam Ebersbach, Eberhard Von Borell

Attention Collection

Previous studies have shown that apes, dogs and horses seem to be able to attribute attentive states to humans. Subjects chose successfully between two persons: one who was able to see the animal and one who was not. Using a similar paradigm, we tested a species that does not rely strongly on visual cues, the domestic pig (Sus scrofa domestica). Subjects could choose between two unfamiliar persons, with only one showing attention, in three different conditions (body, head away, body turned - head front). Subjects (n = 16) only showed a tendency towards …

Conceptualising The Impact Of Arousal And Affective State On Operant Conditioning, Melissa J. Starling, Nicholas Branson, Denis Cody, Paul D. Mcgreevy

Animal Training and Obedience Collection

Animal training relies heavily on an understanding of species-specific behaviour as it integrates with operant conditioning principles. Following on from recent studies showing that affective states and arousal levels may correlate with behavioural outcomes, we explore the contribution of both affective state and arousal in behavioural responses to operant conditioning. This paper provides a framework for assessing how affective state and arousal may influence the efficacy of operant training methods. It provides a series of three-dimensional conceptual graphs as exemplars to describing putative influences of both affective state and arousal on the likelihood of dogs and horses performing commonly desired …

The Effect Of Visual Suggestion On Exercise Motivation And Outcomes, Thomas G. Plante, Ashley Morisako, Justine Folk, Elizabeth Kay, Caroline Read, Ashley Dunn, Angel Perez, Eleanor Willemsen

Psychology

Theories of suggestion and motivation were used to examine if college students exercising in an environment with low or high motivation posters would affect mood, perceived exertion, and exercise workload (i.e., RPM and speed). A total of 134 students (62 males, 72 females) were randomly assigned to one of three conditions while exercising: relaxing posters (i.e., tropical nature), motivational posters (i.e., competitive bikers), or no posters (i.e., control). Participants completed 20 minutes of exercise at their own pace. Measures of mood were taken immediately prior to and following exercise. Exercise workload was recorded throughout. Results indicate that participants in the …

The Case For Conscientiousness: Evidence And Implications For A Personality Trait Marker Of Health And Longevity, Tim Bogg, Brent W. Roberts

Psychology Faculty Research Publications

Purpose Recent initiatives by major funding agencies have emphasized translational and personalized approaches (e.g., genetic testing) to health research and health management. While such directives are appropriate, and will likely produce tangible health benefits, we seek to highlight a confluence of several lines of research showing relations between the personality dimension of conscientiousness and a variety of health-related outcomes.

Methods Using a modified health process model, we review the compelling evidence linking conscientiousness to health and disease processes, including longevity, diseases, morbidity-related risk factors, health-related psycho-physiological mechanisms, health-related behaviors, and social environmental factors related to health.

Conclusion We argue the …
