Mitigating Risk For Anxiety Among Preschool-Age Children Living In Poverty: Evaluating The Impact Of Adult-Provided Social Support On Autonomic Stress Reactivity, Brian Cory Wolff

Electronic Theses and Dissertations

Poverty increases children's exposure to stress, elevating their risk for developing patterns of heightened sympathetic and parasympathetic stress reactivity. Repeated patterns of high sympathetic activation and parasympathetic withdrawal place children at risk for anxiety disorders. This study evaluated whether providing social support to preschool-age children during mildly stressful situations helps reduce reactivity, and whether this effect partly depends on children's previously assessed baseline reactivity patterns. The Biological Sensitivity to Context (BSC) theory proposes that highly reactive children may be more sensitive than less reactive children to all environmental influences, including social support. In contrast, conventional physiological reactivity (CPR) theory contends …

Size Of Food Packaging And Cognitive Performance, Shannon Henry

Honors Theses

Many factors have been shown to affect individuals' cognitive performance, such as sleepiness, hunger, motivation, etc. One such factor that has recently gained much attention is self-regulation, or one's ability to control, regulate, or change his or her behaviors. In lay terms, self-regulation may be thought of more or less as self-control. Together, this researchon self-regulation suggests that it is a limited resource, which, when depleted in one area, reduces self-regulationability across other areas. Many past studies regarding self-regulation have incorporated food as a way to deplete self-regulation. In particular, the size of food packaging may be a way to …

An Exploratory Study Of The Perceptions And Associated Coping Skills Of Children With Attention-Deficit/Hyperactivity Disorder, Rayna Ruth Mckinnon

PCOM Psychology Dissertations

Attention-deficit/hyperactivity disorder (ADHD) affects between 3% and 5% of school-age children. In addition to hyperactivity, difficulty paying attention, and impulsivity, children with ADHD have been found to have lower self-perceptions than their peers who do not have ADHD. Researchers have attempted to explain why children with ADHD have lower self-perceptions. Despite these studies, little research has explored how these children perceive themselves, others, and their world from their perspective. In addition, even fewer researchers have studied how these children cope. The purpose of this study was to delve into the lives of six children with ADHD as a means of …

Extensive Training Is Insufficient To Produce The Work-Ethic Effect In Pigeons, Marco Vasconcelos, Peter J. Urcuioli

Department of Psychological Sciences Faculty Publications

Zentall and Singer (2007a) hypothesized that our failure to replicate the work-ethic effect in pigeons (Vasconcelos, Urcuioli, & Lionello-DeNolf, 2007) was due to insufficient overtraining following acquisition of the high- and low-effort discriminations. We tested this hypothesis using the original work-ethic procedure (Experiment 1) and one similar to that used with starlings (Experiment 2) by providing at least 60 overtraining sessions. Despite this extensive overtraining, neither experiment revealed a significant preference for stimuli obtained after high effort. Together with other findings, these data support our contention that pigeons do not reliably show a work-ethic effect.

Intellectual Ability In Children With Anxiety: A Replication And Exploration Of The Differences, Melissa S. Munson

LSU Master's Theses

The purpose of this study was to examine the effect of anxiety on the intellectual functioning of children. Specifically, the current researchers sought to replicate previous findings that children with higher levels of anxiety have significantly lower scores on tests of intelligence. A second goal was to examine possible reasons for these deficits, including possible deficits in working memory and/or attention. Participants were divided into two groups with high and low anxiety, based on a self-report measure, though none of the children reported clinically problematic anxiety. The participants were 19 children (10 males, 9 females) who were recruited from the …

The Primary Prevention Of Sexual Violence Against Adolescents In Racine County And The Community Readiness Model, Theresa A. Dewalt

Dissertations (1934 -)

Sexual violence affects tens of thousands of people annually in the United States. The majority of sexual assault victims are under the age of 18. Victims of sexual violence often experience severe, long-lasting ramifications, including post-traumatic stress disorder, depression, anxiety, interpersonal problems, suicidal ideation, self-harm behaviors, and eating disorders. As a result of these effects, it is imperative that communities provide effective primary prevention of sexual violence programs. However, it is challenging to effectively implement sexual violence primary prevention strategies for a variety of reasons. One challenge is because it is difficult to construct a prevention program that changes the …

Depression Among The Oneida: Case Studies Of The Interface Between Modern And Traditional, Mark R. Powless

Dissertations (1934 -)

Depression, defined by a EuroAmerican biomedical diagnostic criterion, using the Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition, Text Revision is prevalent among First Nations peoples. However, some studies suggest that the term depression may hold little heuristic value outside of its EuroAmerican conceptualization. This study utilized qualitative methods to understand how depressive symptoms are conceptualized and experienced by traditional Oneida people. A vignette was presented and in-depth interviews of seven traditional healers, culture and Oneida language experts were conducted to: (1) gain a basic understanding of traditional views of mental health, (2) acquire multiple conceptualizations of someone who presents …

Social Construction Of Knowledge In A Semiformal, Long -Term Learning Environment: A Qualitative Study, Alycia Harris

Walden Dissertations and Doctoral Studies

Social learning plays a critical role in cognitive apprenticeship, community of practice, and knowledge production theories. Gunawardena's interaction analysis model, which provides a means of evaluating discourse for social construction of knowledge, is comprised of five phases: (a) sharing and comparing, (b) disagreement, (c) negotiation and co-construction of new knowledge, (d) testing of knew knowledge, and (e) use or phrasing of new knowledge. There is a paucity of research that has empirically explored social construction of knowledge, especially in an extended semiformal asynchronous graduate learning experience. This study explored two research questions: whether social construction of knowledge took place, and …

Leadership As Role And Relationship In Social Dynamics: An Exploratory Study Seeking A Leadership Archetype, Brian W. Bridgeforth

Walden Dissertations and Doctoral Studies

Previous research on leadership as archetype considered archetype as metaphor and not as it is understood in other literatures as a collectively accepted and defined role within and across cultures. Archetypical theories are posited as useful because they help us understand universal aspects of human behavior; however, empirical research demonstrating archetypical thinking and behavior remains rare. Accordingly, this phenomenological study investigated whether a leadership archetype exists as a shared cognitive template and if so, what characteristics define it. The theoretical framework used to examine the phenomenon of leadership combined leadership theory, philosophy of the mind, Jungian psychology, social constructionist theory, …

Visual Contributions To Spatial Perception During A Remote Navigation Task, Candace Lee Eshelman-Haynes

Browse all Theses and Dissertations

The purpose of this study was to explore the implications of perception and action coupling for the design of control and display interfaces in remotely piloted vehicles. Three experiments were conducted: spatial arrangement, path perception, and remote navigation. The results showed that panning independent of forward motion gives observers a greater sense of depth in a scene and aides in efficient navigation while rotation during forward motion results in ambiguities during passive observation. This research has implications for the design of control and visualization interfaces for remote navigation.

Satisfaction With Sexual Health Education Among Recent Graduates Of Ontario High Schools, Glenn J. Meaney

Theses and Dissertations (Comprehensive)

Satisfaction with sexual health education can be seen as student evaluation of how effectively the sexual health education curriculum meets its goals. First-year university students completed one questionnaire containing measures concerning satisfaction with high school sexual health education, sexuality-related individual difference variables, and intentions to pursue further sexual health education at the university level. Question 1 was whether students were satisfied with their high school sexual health education. Results were examined for differences by gender and type of school attended (i.e., public or Catholic). Participants rated sexual health topics as very important; believed that most sexual health education should occur …

Postville: The Emotional Consequences Applying Diagnostic Criteria To A Unique Event, Mollie Katherine Burke

Honors Program Theses

Group interviews were conducted with small groups of Guatemalan women who were affected by the immigration raid in Postville, Iowa. During these interviews, participants responded to questions about emotional reactions in the months following the raid, as well as current emotional states and functioning. The women reported several negative effects, including emotional, social, and economic hardship during the months between the raid and the interviews. The way in which these responses correlate to the traditional model for Posttraumatic Stress Disorder allows insight into the appropriateness of diagnostic criteria. As similar raids are conducted, it is vital to have an understanding …

Oestradiol Level And Opportunistic Mating In Women, Kristina M. Durante, Norman P. Li

Research Collection School of Social Sciences

The ovarian steroid hormone oestradiol plays a crucial role in female fertility, sexual motivation and behaviour. We investigated the relationship between oestradiol and the likelihood that women would engage in opportunistic mating. Two salivary samples were taken from normally cycling women within the peri-ovulatory and luteal phase of the menstrual cycle. At both testing sessions, participants also completed selfperceived desirability scales and provided subjective reports of sexual and social motivations, and satisfaction with their primary relationship partner. Oestradiol level was positively associated with a woman’s self- and other-perceived physical attractiveness and with inclinations to mate outside her current relationship. Oestradiol …

Memory Aging: Deficits, Beliefs, And Interventions, Jane M. Berry, Erin Hastings, Robin West, Courtney Lee, John C. Cavanaugh

Psychology Faculty Publications

Of all mental faculties, memory is unique. It defines who we are and places our lives on a narrative continuum from birth to death. It helps to structure our days, it guides our daily tasks and goals, and it provides pleasurable interludes as we anticipate the future and recall the past. As a core, defining feature of the self (Birren & Schroots, 2006), memory takes on heightened meaning as we age. In the face of other losses that accumulate with age, memory can serve to preserve our sense of self and place in time. In normal aging, memory loss is …

A Three Part Study Exploring Psi-Conduciveness And Psi-Defensiveness In Groups, Gretchen M. Conner

Masters Theses

The current study examined three separate experiments, conducted during the Spring semester of 2006, designed to explore variables related to telepathy performance. The common theme which runs through all studies in the parapsychology laboratory including the three experiments covered in this document is the exploration of variables related to psi-defensiveness and psi-conduciveness within groups of participants. In Part I, groups of participants were rated by research assistants on the dimensions of friendliness and enthusiasm. It was hypothesized that as friendliness and enthusiasm ratings increased or decreased for a session, hit rates would correspondingly increase or decrease. Results indicated that as …

Using The Web To Effectively Attract Volunteers To Non-Profit Organizations, Adrian Goh, Joseph A. Allen, Steven G. Rogelberg, Anna Currie

Psychology Faculty Publications

Non-profit organizations often rely on volunteers to help staff and sustain organizational services, functions, and programs. The web is a critical vehicle for attracting these needed volunteers. The authors searched the available literature and reviewed close to 100 non-profit organizational websites to identify best practices of note. Fourteen best practices in web site design are forwarded and discussed.

A Genome Scan For Quantitative Trait Loci Affecting Male Reproductive Traits In A White Duroc × Chinese Erhualian Resource Population, Dongren Ren, J. Ren, Y. Y. Xing, Y. M. Guo, Y. B. Wu, G. C. Yang, H. R. Mao

Psychology Faculty Publications

Chinese Erhualian boars have dramatically smaller testes, greater concentrations of circulating androgens, and fewer Sertoli cells than Western commercial breeds. To identify QTL for boar reproductive traits, testicular weight, epididymal weight, seminiferous tubular diameter at 90 and 300 d, and serum testosterone concentration at 300 d were measured in 347 F₂ boars from a White Duroc × Chinese Erhualian cross. A whole genome scan was performed with 183 microsatellites covering 19 porcine chromosomes. A total of 16 QTL were identified on 9 chromosomes, including 1% genome-wide significant QTL for testicular weight at 90 and 300 d and seminiferous tubular …

Construct Validity And Diagnostic Utility Of The Cognitive Assessment System: Discriminating Individuals With Adhd From Random Normals, Allison R. Gaboury

Masters Theses

This study examined the construct validity and diagnostic utility of the Cognitive Assessment System (Naglieri & Das, 1997). Distinct group differences and discriminative validity of 40 kindergarten through second grade students (20 meeting ADHD criteria on the Structured Diagnostic Interview for Parents and the Adjustment Scales for Children and Adolescents, 20 random matched control) on measures of Planning, Attention, Simultaneous, and Successive Processing were completed. The ADHD and random matched control groups differed significantly on Planning and Attention scores with large effect sizes but not on Simultaneous or Successive scores. Low Planning and Attention scores but normal Simultaneous and Successive …

Evidence For Menstrual Cycle Shifts In Women’S Preferences For Masculinity: A Response To Harris (In Press) “Menstrual Cycle And Facial Preferences Reconsidered", Lisa Debruine, Benedict C. Jones, David Frederick, Martie Haselton, Ian S. Penton-Voak, David I. Perrett

Psychology Faculty Articles and Research

Over the last decade, a growing literature has shown that women in the fertile phase of the menstrual cycle demonstrate stronger preferences for men with masculine traits than they do when in the non-fertile phases of the cycle (see Gangestad and Thornhill, 2008 and Jones et al., 2008 for recent reviews). In a recent article, Harris (in press; Sex Roles) failed to replicate this increase in women's preferences for masculine faces when women are near ovulation. Harris represented her study as one of only three studies on the topic, and as the largest of the existing studies. There are, however, …

Adaptive Rationality: An Evolutionary Perspective On Cognitive Bias, Martie Haselton, Gregory A. Bryant, Andreas Wilke, David Frederick, Andrew Galperin, Willem E. Frankenhuis, Tyler Moore

Psychology Faculty Articles and Research

A casual look at the literature in social cognition reveals a vast collection of biases, errors, violations of rational choice, and failures to maximize utility. One is tempted to draw the conclusion that the human mind is woefully muddled. We present a three-category evolutionary taxonomy of evidence of biases: biases are (a) heuristics, (b) error management effects, or (c) experimental artifacts. We conclude that much of the research on cognitive biases can be profitably reframed and understood in evolutionary terms. An adaptationist perspective suggests that the mind is remarkably well designed for important problems of survival and reproduction, and not …

The Lived Experience Of Hiv-Positive Tanzanian Orphans, Carol A. Parker

Walden Dissertations and Doctoral Studies

The purpose of this investigation was to generate a context- specific model of the lived experience of HIV positive Tanzanian orphans. With the advent of anti-retroviral drugs, Sub-Saharan African populations with high burdens of human immunodeficiency virus (HIV) face annually accumulating increases in the number of HIV positive children, and ultimately adults. Perinatally infected, these children often become orphans while still young. Extended interviews were performed with a purposive sample of 12 HIV infected orphaned children between 9 and 12 years of age. Half of the research participants lived in an orphanage and half were children living with guardians in …

Ethical Challenges And Opportunities At The Edge: Incorporating Spirituality And Religion Into Psychotherapy, John C. Gonsiorek, P. Scott Richards, Kenneth I. Pargament, Mark R. Mcminn

Faculty Publications - Doctor of Psychology (PsyD) Program

Incorporating spirituality and religion into psychotherapy has been controversial, but recent contributions have argued the importance and provided foundations for doing so. Discussions of ethical challenges in this process are emerging, and this contribution discusses several preliminary issues, relying on the Resolution on Religious, Religion-Based and/or Religion-Derived Prejudice adopted by the American Psychological Association in 2007, as guidance when used with the American Psychological Association’s (2002) Ethical Principles of Psychologists and Code of Conduct. Specifically, this discussion of preliminary challenges addresses competence, bias, maintaining traditions and standards of psychology, and integrity in labeling services for reimbursement. Commentators deepen the discussion, …

The Influence Of Individualist-Collectivist Values, Attitudes Toward Women, And Proenvironmental Orientation On Landscape Preference, Jessica L. Wilson

UNF Graduate Theses and Dissertations

The purpose of this study was to explore individual variables affecting preferences for natural or managed landscapes. Environmental attitudes and value systems of student participants (N = 147) were assessed using the revised New Ecological Paradigm (NEP) scale and the Scenarios for the Measurement of Collectivism and Individualism (SMCI) scale, respectively. In addition, feminist orientation was assessed using the Attitudes toward Woman scale (AWS). The hypothesis that proenvironmental attitudes would be positively correlated with a preference for natural landscapes was supported. However, hypotheses that alignment with collectivist values would correlate positively with a preference for natural landscapes and that a …

Effects Of Concurrent Task Performance On Object Processing, Gabriela Durán

Open Access Theses & Dissertations

Most research on visual object identification focus on the bottom-up processes of the visual what? and where? pathways. However, such research has not been able to fully account for many visual abilities (e.g., identifying an object among many other objects and across changing conditions). Neurological evidence has shown that feedback from high-level areas (i.e., top-down processing) makes object processing more efficient. However, there are no behavioral studies that have tested this. Thus, four experiments used a concurrent n-back task to occupy higher-level areas and tested its effects on visual object processing relative to a number-repetition control task.

Experiment 1 examined …

Palpable Pedagogy: Expressive Arts, Leadership, And Change In Social Justice Teacher Education (An Ethnographic/Auto-Ethnographic Study Of The Classroom Culture Of An Arts-Based Teacher Education Course), Lucy Elizabeth Barbera

Antioch University Dissertations & Theses

Palpable Pedagogy: Expressive Arts, Leadership, and Change in Social Justice TeacherEducation is an arts-informed ethnographic study of the pedagogy and culture engendered when the expressive arts are employed in social justice teacher education. Palpable Pedagogy is a qualitative study that examines the power of the expressive arts to identify, explore, and address issues of inequity in the context of a social justice teacher education course that I taught over three consecutive years. The literature in the field outlines the essential components for effective social justice teacher education (identity, reflection, and dialogue) and neatly explores them. However, with the exception of …

Characterization Of The Behavioral And Neurochemical Effects Of Nicotine Withdrawal In Adolescent And Adult Rats., Luis Alberto Natividad

Open Access Theses & Dissertations

Previous studies have demonstrated that the behavioral effects of nicotine withdrawal are lower in adolescent versus adult rats. However, the neurochemical mechanisms that mediate these developmental differences are presently unclear. Much work has shown that nicotine reward is mediated via enhanced dopamine neurotransmission in the mesolimbic pathway which originates in the ventral tegmental area (VTA) and terminates in several forebrain structures including the nucleus accumbens (NAcc). More recently, studies have shown that nicotine withdrawal produces a decrease in NAcc dopamine transmission, an effect that is believed to serve as a neurochemical marker of withdrawal in adult rodents. The goal of …

Children's Use Of The Shape Bias In The Presence Of Different Instructions, Object Types, And Emotion Cues, Vanessa Raschke

Master's Theses

This study explored the prevalence of the shape bias in children when faced with multiple perceptual cues. Three-to six-year-olds were shown three-dimensional objects and two-dimensional representations of these objects, half of which had emotional faces depicted on them. Of interest was whether attention to emotion would alter children's bias towards the shape of the object and how dimensionality and instruction type would affect the children's choices. The older children were equally likely to use emotion matches as shape matches, but this was not the case for the younger children, who were almost exclusively focused on shape. The non-lexical instructions induced …

Caretaker Ratings Of Attention Problems In Maltreated Children : The Effects Of Gender, Age, And Type Of Maltreatment, Dawn M. Mcdonald

PCOM Psychology Dissertations

Child maltreatment is a severe stressor which is associated with a variety of adverse outcomes, including attention, learning, and behavior problems. Attention problems are common in maltreated children, with rates of ADHD in samples of abused and neglected children consistently higher than those found in the general population or in clinical samples of children without abuse histories. Despite the association between ADHD and maltreatment, attention problems in maltreated children remain poorly characterized and not well understood. In an attempt to better delineate the nature of attention problems in maltreated children, this study examined the effects of age, gender, type of …

Molluscan Memory Of Injury: Evolutionary Insights Into Chronic Pain And Neurological Disorders, Edgar T Walters, Leonid L Moroz

Faculty, Staff and Student Publications

Molluscan preparations have yielded seminal discoveries in neuroscience, but the experimental advantages of this group have not, until now, been complemented by adequate molecular or genomic information for comparisons to genetically defined model organisms in other phyla. The recent sequencing of the transcriptome and genome of Aplysia californica, however, will enable extensive comparative studies at the molecular level. Among other benefits, this will bring the power of individually identifiable and manipulable neurons to bear upon questions of cellular function for evolutionarily conserved genes associated with clinically important neural dysfunction. Because of the slower rate of gene evolution in this molluscan …
