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 …

A Study Of The Cognitive Profiles Of Medicated And Nonmedicated Children Diagnosed With Attention Deficit Hyperactivity Disorder, Amy E. Mclaughlin

PCOM Psychology Dissertations

Attention Deficit Hyperactivity Disorder is among the most commonly diagnosed childhood disorders, with symptoms that can cause significant difficulties in the educational setting. Deficits related to working memory and processing speed are thought to be a core feature of ADHD. As such, research using traditional measures of cognitive functioning has shown that children diagnosed with ADHD tend to perform poorly on measures of processing speed and working memory, relative to non-ADHD individuals and relative to measures of other cognitive abilities. Psychostimulant medication is a common treatment for ADHD and research overwhelmingly supports its positive impact on behavior and concentration; however, …

The Culture Connection: Testing A Model Of African American Attitudes Toward Mental Health Service Utilization, Andrea Michelle Smith

University of Kentucky Doctoral Dissertations

The purpose of the current study was to combine the factors previously determined to be related to African American help seeking into a single path model and, using structural equation modeling (SEM), determine the relative influence of each factor in the attitudes toward seeking mental health services (see Figure 2.2) among a community sample of African American adults from several metropolitan areas in the US. As such, SEM was utilized to compare the relative fit of two opposing models within this sample, one where a path from economic barriers to help-seeking attitudes was estimated freely and one where that path …

Does Type Of Stimulus Influence Task-Irrelevant Evaluative Categorization Processes?, Guadalupe Corral

Open Access Theses & Dissertations

The effect of stimulus type on task-irrelevant evaluative categorization was examined in two separate studies by using the P3 component from event-related brain potentials. The first study presented idiosyncratic stimuli consisting of individuals that were rated by participants as either positive or negative within sequences of pictorial and verbal stimuli. The second study presented sequences of novel and familiar stimuli consisting of previously normed unattractive and neutral individuals. It was hypothesized that pictures would elicit task-irrelevant evaluative categorization processes and so would novel stimuli (relative to words and familiar stimuli, respectively). Task-irrelevance was examined by assessing P3 peak amplitude to …

Kicking To Bigger Uprights: Field Goal Kicking Performance Influences Perceived Size., Jessica Witt, Travis E. Dorsch

Department of Psychological Sciences Faculty Publications

Perception relates not only to the optical information from the environment but also to the perceiver’s performance on a given task. We present evidence that the perceived height and width of an American-football field goal post relates to the perceiver’s kicking performance. Participants who made more successful kicks perceived the field goal posts to be farther apart and perceived the crossbar to be closer to the ground compared with participants who made fewer kicks. Interestingly, the current results show perceptual effects related to performance only after kicking the football but not before kicking. We also found that the types of …

The Stability Of Psychopathy Across Adolescence, Donald Lynam, Richard Charnigo, Terrie E. Moffitt, Adrian Raine, Rolf Loeber, Madga Stouthamer-Loeber

Department of Psychological Sciences Faculty Publications

The current diagnostic system suggests that personality disorder categories be applied to children and adolescents in rare circumstances because of expected changes in personality pathology across development. The present study examined the stability in personality pathology, specifically psychopathy, across childhood and adolescence. Using a short form of the CPS and mixed models incorporating fixed and random effects, we examined the reliability, individual stability, mean-level stability, and predictive utility of juvenile psychopathy as a function of age (i.e., from 7 to 17 years old) in over 1,500 boys from the three cohorts of the Pittsburgh Youth Study. If adolescent development contributes …

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 …

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 …

The Role Of Resilience And Purpose In Life In Habituation To Heat And Cold Pain, Bruce W. Smith, Erin M. Tooley

Arts & Sciences Faculty Publications

This study examined the role of resilience in habituation to heat and cold pain in healthy women (n = 47). Heat and cold pain thresholds were each assessed across 5 equally spaced trials. Re- silience, purpose in life, optimism, social support, and neuroticism were assessed using self-report measures. The hypothesis was that the resilience and the associated resilience factors would be pos- itively related to habituation to heat and cold pain while controlling for neuroticism. Multilevel mod- eling was used to test the hypothesis. When considering each characteristic separately, resilience and purpose in life predicted greater habituation to heat pain …

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.

Using Thr Ffm To Understand And Integrate The Deficits Of Psychopathy, Karen J. Derefinko

University of Kentucky Doctoral Dissertations

Psychopathy is associated with several behavioral and psychophysiological deficits. Lynam (2002) has argued that the use of an overarching conceptualization of psychopathy can provide a parsimonious explanation of psychopathic pathology. The current study examined relations between tasks used to explore psychopathic pathology and dimensions from the Five Factor Model of personality. Undergraduate participants completed the NEO PI-R, the BART, a go/no-go task, an emotional morph task, and provided physiological responses to stimuli. While hypothesized relations to FFM psychopathy composites were generally unsupported, other interesting relations to traits were identified. Results indicated that hypoarousal to negative stimuli was negatively related to …

Emotional Reactivity Across Individuals With Varying Trauma And Substance Dependence Histories, Alicia K. Klanecky, Dennis E. Mcchargue

Department of Psychology: Faculty Publications

Background—Research has reported a high rate of substance dependence in traumatized individuals who do not develop PTSD (TWP). While past studies have failed to consistently demonstrate that TWP individuals experience PTSD symptoms, findings have indicated that TWP and a history of substance dependence aside from nicotine dependence (SDH) are linked to affect disruption.

Aims—The present study explored positive and negative affective mechanisms across four groups with varying SDH and TWP including TWP + SDH, TWP only, SDH only, or no history. Researchers hypothesized that adults (n = 78) would be more emotionally reactive to an experimentally-induced negative mood compared to …

Forced Abstinence Model Of Relapse To Study Pharmacological Treatments Of Substance Use Disorder, Carmela M. Reichel, Rick A. Bevins

Department of Psychology: Faculty Publications

Understanding and preventing relapse to drug use is one of the most difficult challenges faced by clinicians and practitioners in the struggle to help people remain abstinent. In this paper, we review basic preclinical research on forced abstinence periods that identify the neural substrates involved and neural adaptations that occur after a drug-free period. Our attention focuses on forced abstinence after self-administration because of its promise for translational research in the development of candidate medications to reduce relapse. This model requires subjects (often rats) to initially acquire drug self-administration. However, rather than extinguishing behavior with daily drug-free sessions as in …

Neuropharmacology Of The Interoceptive Stimulus Properties Of Nicotine, Thomas E. Wooters, Rick A. Bevins, Michael T. Bardo

Department of Psychology: Faculty Publications

Preclinical drug discrimination techniques play a significant role in advancing our knowledge of the receptor mechanisms underlying the interoceptive effects of nicotine. Early reports confirmed that nicotinic acetylcholine receptors (nAChRs) are critical for transduction of the nicotine cue. In recent years, advances in molecular biology and the discovery of novel ligands with greater selectively for specific nAChR subtypes have furthered our understanding of these mechanisms. There is now evidence regarding the specific nAChR subtypes involved in nicotine discrimination; in addition, there is also evidence suggesting that other systems (i.e., adenosine, cannabinoid, dopamine, glutamate and serotonin) may play a modulatory role. …

Viewing Preschool Disruptive Behavior Disorders And Adhd Through A Developmental Lens: What We Know & What We Need To Know, Anil Chacko, Lauren Wakschlag, Carri Hill, Barbara Danis, Kimberly A. Espy

Department of Psychology: Faculty Publications

There is now little doubt that DSM-IV behavior disorders are present and identifiable during the preschool years (1,2). With only minor modifications to DSM-IV Disruptive Behavior Disorders (DBDs) and attention-deficit/hyperactivity disorder (ADHD) nosology, multiple, independent studies have shown similar prevalence rates and correlates as in older children (1). In the preschool age range, these disorders also have modest stability (3-6). It is clear that the behaviors that comprise DBDs and ADHD (e.g., noncompliance, rule-breaking, aggression, destruction of property, hyperactivity, inattention, and impulsivity) impair children’s functioning and that caregivers of young children often experience considerable difficulty in managing those who exhibit …

An Exploratory Study On Reaction Time To Valenced Memories: The Importance Of Individual Differences, Emrah Ates

Theses : Honours

It is commonly accepted that valence has influences on long-term memory, but there are diverse results concerning methodology and the effect size. The literature is mixed with some authors reporting evidence consistent with negativity bias, others reporting evidence consistent with positivity bias and still others reporting no effect of valence on certain types of memory. This review argues that while there are divergent results for recall rate studies, reaction time studies and emotional Stroop task studies showed predominant negativity bias in long term memory. Moreover, many of the studies reviewed were solely concerned with group effects, rather than individual differences. …

An Exploration Of The Experiences Leading To Volunteer Facilitation Of Postnatal Depression Peer Support Groups, Tracey Parker

Theses : Honours

In recent years literature regarding peer support recovery services has been more prominent. However, little attention has been paid to how these services are used to treat postnatal depression and questions regarding what informs a consumer's decision to become a support person to others remain. The aim of this study was to explore women's postnatal depression and how their experience and recovery informed a decision to become a peer support group facilitator. Participants were eight women who were past or current facilitators with the Post Natal Depression Support Association Inc. (PNDSA). In-depth conversational style interviews were conducted with participants and …

Qualitative And Quantitative Methods In Occupational-Stress Research, Irvin Sam Schonfeld, Edwin Farrell

Publications and Research

The paper examined the ways in which qualitative and quantitative methods support each other in research on occupational stress. Qualitative methods include (a) eliciting from unconstrained descriptions of work experiences, (b) careful first-hand observations at the workplace, and (c) participant‑observers describing “from the inside” a particular work experience. The paper shows how qualitative research stimulates theory development, hypothesis generation, and the identification of job stressors and coping responses. The limitations of qualitative research, particularly in the area of verification, are also described.

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 …

Context-Based Assessment And Intervention For Problem Behavior In Children With Autism Spectrum Disorder, Sanja I. Cale, Edward G. Carr, Audrey Blakeley-Smith, Jamie S. Owen-Deschryver

Peer Reviewed Articles

The present study used a context-based model of assessment and intervention to explore whether interventions that modify context result in reduction of problem behavior in ecologically valid settings (i.e., typical routines implemented by typical education personnel in neighborhood schools). The Contextual Assessment Inventory (CAI) and a post-assessment interview were administered to parents and teachers of eight children with Autism Spectrum Disorder to identify problem contexts. Then, environmental modification techniques were implemented in three priority contexts: namely, transitions, termination of preferred activities, and presence of a feared stimulus. Our results demonstrated an almost complete elimination of problem behavior in the priority …

Attention Deficit Hyperactivity Disorder In Elementary School Children In A Rural Illinois School District, Amy M. Miller

Masters Theses

Attention Deficit Hyperactivity Disorder (ADHD), one of the most commonly diagnosed childhood disorders, adversely affects children's academic, social, and emotional functioning. There were three purposes for this study. First, this study attempted to determine the number of students diagnosed with ADHD in the three elementary schools of a rural Midwestern school district as reported by parents. Secondly, the study attempted to discover discrepant practices in the methods of diagnosis and treatment ofADHD for students from a lower socioeconomic status than for those from the middle or upper class as reported by the parents. Thirdly, this study assessed teachers' knowledge and …

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 …

Gender And Performance In The Mathematics' Sections Of The Illinois Standards Achievement Test And The Prairie State Achievement Exam, Lindsey Leaf

Masters Theses

Despite criticisms about their inability to assess students' learning accurately, high stakes tests are currently used in the United States to measure student and teacher progress. Because of the need for schools to demonstrate students have achieved or maintained satisfactory progress, schools in Illinois regularly administer the Illinois Standards Achievement Test (ISA T) and Prairie State Achievement Exam (PSAE), despite limitations in the statistical and technical infonnation available for both of these tests. This study examined possible gender differences on the mathematics portion of the ISA T and PSAE by gathering data from one school district in Illinois. Findings indicated …

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 …

Facets Of Mindfulness As Predictors Of Resistance To Alcohol-Related Disorders, Jacob Landers

Masters Theses

Mindfulness is defined as a state of mind, a tendency and willingness to 'bring one's complete attention to the experiences occurring in the present moment in a nonjudgmental and accepting way' (Brown & Ryan, 2003). The concept originated from the Eastern spiritual traditions and has recently made its way to the West. Although mindfulness-based practices have met with success in alleviating a wide range of problematic conditions such as depression, anxiety, and addiction, it is still unclear as to which specific dimensions of mindfulness are responsible for the positive effects. Baer, Smith, Hopkins, Krietemeyer, and Toney (2006) extracted five facets …

Relationship Between Theory Of Mind Performance In A Nonverbal Task And Functioning Level Of Children With Autism, Michael J. Grenda

Masters Theses

Individuals with autism often show deficits in Theory of Mind (ToM), their ability to understand the perceptions of others. The relationship between functioning level and ToM abilities in children with autism has not been adequately explored. This study utilized a nonverbal task of ToM adapted from previous research (Colle, Baron-Cohen, & Hill, 2007) which allowed examination of lower functioning or nonverbal individuals. Participants included nine individuals with autism spectrum disorders and nine normally developing individuals. Functioning level was estimated using a brief autism rating scale. When controlling for nonverbal abilities and age, no significant differences in ToM abilities were found …

Globalization And Identity: A Cross-National Study Among Chinese, Indian, Colombian, And American College Students, Min Cheng

Electronic Theses and Dissertations

Arnett (2002) has suggested the development of a typology similar to one that has become popular in the ethnic identity literature (Berry, 1993; Phinney, 1990) whereby people are surveyed in terms of strength of identification with both the dominant national culture and their particular sub-group minority culture. Based on this typology, we have developed a paper and pencil measure, the Global Identity Survey (GIS), which asks participants about the degree to which they identify with either the local or global culture. A new typology is proposed, with behaviors and attitudes falling into one of the four following categories: "locally encapsulated" …

Neurocognitive Correlates Of Body Image Disturbance, Elizabeth Frei

Electronic Theses and Dissertations

Body image, broadly defined as an individual's general experience of his or her physical appearance, is a multidimensional phenomenon that has been found to affect functioning throughout the lifetime. Although some degree of dissatisfaction has been found to be a common aspect of the female experience, research suggests that a disturbance in body image can result in a number of clinical complications, particularly the development of an eating disorder (ED). Despite the relationship between body image and EDs, examinations of the cognitive underpinnings of the relationship between body image disturbance and EDs are relatively few and inconclusive. Research indicates that …

A Multivariate Model Of Parent-Adolescent Relationship Variables In Early Adolescence, Cliff Mckinney

Electronic Theses and Dissertations

The purpose of this study is to examine a multivariate model of parent-adolescent relationship variables, including parenting, family environment, expectations and conflict. These variables are examined simultaneously to investigate their relationships with adolescent adjustment in early adolescence. The sample for the current study consists of 710 culturally diverse participants who range in age from 11- to 14-years and who attend a middle school in a Southeastern state. Of these participants, 487 have a mother and father who participated in this study as well. Correlation analyses indicate that parental warmth and overprotection, family cohesion and adaptability, developmental expectations, and conflict are …

Elevated Corticotropin-Releasing Hormone In Human Pregnancy Increases The Risk Of Postpartum Depressive Symptoms, Ilona S. Yim, Laura M. Glynn, Christine Dunkel Schetter, Calvin J. Hobel, Aleksandra Chicz-Demet, Curt A. Sandman

Psychology Faculty Articles and Research

Postpartum depression (PPD) is common and has serious implications for the mother and her newborn. A possible link between placental corticotropin-releasing hormone (pCRH) and PPD incidence has been discussed, but there is a lack of empirical evidence.
