Stress Of College Students And Memory With The Implementation Of Brief Mindfulness, Rebecca Lopez

Walden Dissertations and Doctoral Studies

College students are faced with stressors which can negatively impact memory function, thereby, negatively affecting academic performance. This study used a field experiment design to investigate the effects of brief mindfulness on levels of distress and memory functioning between first-year community college students engaging in a brief mindfulness intervention (n = 29) and a control group (n = 28) by using ANCOVA, MANOVA, correlations, and descriptive statistics. Research questions examined whether a brief mindfulness intervention lowered levels of distress in a treatment group. Second, the study examined whether the intervention of brief mindfulness in a treatment group improved memory function. …

Thinking Perspective Profiles As A Predictor Of Intelligence Analysts' Job Performance., Curtis Rasmussen

Walden Dissertations and Doctoral Studies

Empirical research has supported the use of general cognitive ability to predict employee performance; however, studies have accounted for only a fraction of the variance. The current study addressed whether intellectual styles, which describe how individuals habitually acquire and use information, account for a significant portion of the variance in job performance not covered by general cognitive ability. The study followed a quantitative, nonexperimental design with a convenience sample of 77 intelligence analysts from 6 U.S. government agencies and 2 online professional groups. MindTime provided the primary theoretical framework. The International Cognitive Ability Resource, MindTime Profile InventoryTM, and Self-Rated Analytic …

Determining Criteria For Distinguishing States Of Consciousness, Barry Matthew Klein

Walden Dissertations and Doctoral Studies

Even though there are many views on consciousness theory in the pertinent literature, there remains a need for a unifying framework for specifying the features of specific states of consciousness. In order to know what kinds of experiences conscious states have in common, researchers need to elicit testimony that is more direct and finer-grained than has been previously available. This dissertation endeavors to fill a gap in current research by addressing concepts and methods for making requisite distinctions. This research illuminates the question of whether specific states of consciousness can be reliably and validly distinguished from each other. In order …

Problem Solving, Decision Making, And Kirton Adaption-Innovation Theory In High-Performance Organizations, Miriam Grace Michael

Walden Dissertations and Doctoral Studies

Research on high-performing nonprofit boards has indicated a positive relationship between a board's strength and an organization's effectiveness; however, how boards achieve success remains relatively unknown. The Kirton adaption-innovation (KAI) theory was used to examine board members' cognitive styles in relationship to facilitating problem solving and decision making. This nonexperimental, quantitative study included archived nonprofit board data from 2 American Society of Association Executives (ASAE) studies that had addressed the high performance of boards and factors associated with organizational success. A total of 102 randomly selected, high-performing nonprofit board members completed the KAI Inventory, which was used to measure cognitive …

Quantitative Assessment Of Psycho-Social Factors Associated With Alcoholics Anonymous Involvement, Dianne Bentley

Walden Dissertations and Doctoral Studies

Alcohol use disorders are a major health problem in the United States; approximately 7.4% of the population meets the criteria for alcohol abuse or dependence. However, Reed, Levin, and Evans (2012) reported a lack in research regarding alcoholism's risk factors and how these influence Alcoholics Anonymous involvement. Though there is evidence for several risk factors, researchers have found mixed results regarding gender and impulsivity. Social learning theory was the theoretical foundation of this study and guided the exploration and interpretation of these risk factors. Therefore, the purpose of this quantitative, nonexperimental study was to understand the relationship that impulsivity (as …

Effect Of Attentional Capture And Cross-Modal Interference In Multisensory Cognitive Processing, Michael Jennings

Despite considerable research, the effects of common types of noise on verbal and spatial information processing are still relatively unknown. Three experiments, using convenience sampling were conducted to investigate the effect of auditory interference on the cognitive performance of 24 adult men and women during the Stroop test, perception of object recognition and spatial location tasks, and the perception of object size, shape, and spatial location tasks. The data were analyzed using univariate analysis of variance and 1-way multivariate analysis of variance. The Experiment 1 findings indicated reaction time performance for gender and age group was affected by auditory interference …

Individual Ability To Learn A Parallel Processing Technique And Musical Aptitude., Daniel Warren Emmett

Walden Dissertations and Doctoral Studies

Correlations between music training and psychosocial skills, sensory abilities, and aspects of intelligence, are sorted into primary or secondary effects. Correlations between these areas of human development and music training lack support pertaining to the underlying cognitive networks that these processes rely on. Thus, this study was based on the work of Baddeley and Hitch's model of working memory, and implemented a test of parallel processing (Articulatory Suppression Task, AST), which measures proficiency of working memory systems. Individual differences therein, were compared with music aptitude. Participants were gathered throughout urban and rural regions of the state of Oregon. Half the …

Lived Experiences Of Mothers Raising Children With Autism Spectrum Disorder In Nigeria, Joyce Itseme Ulofoshio

Walden Dissertations and Doctoral Studies

Autism has no cure, but early and appropriate diagnosis and intervention may increase outcomes for individuals affected. The level of awareness, acceptance, and support for autism spectrum disorder (ASD) in Nigeria is very low. There is a gap in the literature regarding a detailed account of the experiences of parents raising children with ASD within the Nigerian environment and culture. The purpose of this phenomenological study was to explore the perceptions and lived experiences of mothers raising children with ASD in Nigeria including the impact of Nigerian culture on their experiences. Bronfenbrenner’s ecological systems theory was the guiding conceptual framework …

The Experience Of Forgiveness In Adults With Different Sacred Belief Systems, Christy Jo Heacock

Walden Dissertations and Doctoral Studies

Forgiveness is the act of moving beyond shame, guilt, anger, or blame, and it has been linked to psychological well-being, prosocial behavior, and religion/spirituality (R/S). However, the research on why and how people forgive is inconsistent, as the concepts involved are complex and difficult to define and operationalize. The purpose of this interpretative phenomenological analysis (IPA) was to provide a better understanding of why and how people are cognitively and emotionally able to forgive and the role of R/S in that process. Goal orientation and cognitive restructuring theories were used as frameworks for understanding the forgiveness experience. First-person, semistructured interviews …

Ask A Busy Person? A Reexamination Of Cognitive Performance Under Load, Graham Watson

Walden Dissertations and Doctoral Studies

A longstanding folk belief suggests that 'busy' people possess the ability to get more done than others. Busyness, defined as the demands of everyday life, has been shown to generate cognitive load, which has been called 'cognitive busyness.' Although most cognitive theory would deny the possibility that cognitive load may enhance performance, some recent research may support the possibility. Cowan's 1988 information-processing model was used to study how measures of everyday busyness correlated with performance on cognitive tasks. The research question addressed whether any combination of such measures, in combination with working memory, could predict performance on such tasks. 92 …

Recidivism Rates Among Juveniles With Mental Illness, Kia Chevon Russell

Walden Dissertations and Doctoral Studies

Treating mental illness is imperative to help reduce criminal justice involvement within the juvenile population. Receiving mental health care will help decrease the likelihood for youth to reoffend, ultimately reducing recidivism rates. Past studies showed there are risk factors associated with juveniles and recidivism; however, very few studies have examined what factors are prevalent after services have been received. The purpose of this study was to identify factors that increase the risk of recidivism among juveniles who have received psychiatric stabilization in Harris County, Texas. Risk factors that were assessed included age, gender, ethnicity, and criminal offense. The psychodynamic perspective …

The Relationship Between Childhood Maltreatment And Sexual Coercion Proclivity In Women, Christina Renee Dean

Walden Dissertations and Doctoral Studies

Researchers have explored the effects of sociocultural factors on male and female sexual expression, as well as the relationship between sexual objectification and overall sexual well-being; however, few scholars have focused on how, when combined with early experiences of childhood maltreatment, such factors can result in increased long-term risks for a variety of concerns that may impede the development of healthy relationships in women. This quantitative study explores the relationship of childhood maltreatment and sexual coercion proclivity in adult women. The purpose of this study was to measure self-reports of 1 or more experiences with childhood maltreatment (i.e., physical, sexual, …

The Relationship Between Coping Strategies And Burnout For Caregivers Of Adjudicated Youth, Debra Marie Dix

In the human services field little is known about the impact of coping strategies on the problem of burnout for primary caregivers of delinquent youth in placement. The purpose of this correlational research was to examine the relationship between coping strategies, youth psychopathology, and burnout. This study was based on Maslach's theory of burnout and Lazarus and Folkman's transactional model of stress and coping. To assess the prevalence of burnout and coping strategies, 82 primary caregivers of adjudicated youth in placement in the state of Michigan, completed self-report questionnaires: the Maslach Burnout Inventory, the Brief COPE Inventory, and the Child …

Parents And Teachers’ Perceptions And Clinical Diagnosis Of Autism Among White And Non-White Groups, Margaret Gopaul

School of Psychology Publications

The pervasiveness of autism has significantly increased over the past 2 decades with the 2014 Center for Disease Control and Prevention report indicating 1 in 68 children are diagnosed with Autism Spectrum Disorder (ASD). Early intervention is recommended as the most effective treatment approach. Nevertheless, previous research has indicated that White children are diagnosed with ASD about 1.5 years earlier than are Non-White children. A current gap remains in literature regarding ASD and different racial groups, and evidence has been inconclusive regarding disparities in identifying and diagnosing ASD. To fill this gap, this study investigated the relationship between child race, …

Cognitive Processes And Memory Differences In Recall And Recognition In Adults, Laura Elaine Fitzgerald

Walden Dissertations and Doctoral Studies

Eyewitness testimony is critical in both criminal court and civil court, so determining the most reliable method to gain information from witnesses is imperative. Past research in this area has focused on false memory, assisted recall, stress, and event perception. A gap exists in the current literature regarding the best method to gain the most accuracy in recall. The purpose of this study was to evaluate free recall, cued recall, and recognition, in an attempt to examine the accuracy of eyewitness memory. The study utilized a quantitative design to assess the accuracy of eyewitness memory as measured by results on …

Relationship Between Autonomous Motivation And Ego-Depletion, Mark A. Heilman

Walden Dissertations and Doctoral Studies

Previous research has shown that exerting self-control on a demanding task can impair performance on a subsequent demanding self-control task. This phenomenon is known as ego-depletion; however, its underlying mechanisms are not well understood. Notable gaps in the literature exist regarding whether participants’ motivation levels can attenuate the depletion effect, and whether trait self-control is related. Drawing from the process model of depletion and the self-determination theory, the goal of the study was to examine whether motivational incentives in the form of autonomy can impact performance on tasks in an ego-depleted state, and the potential relationship of trait self-control. Amazon …

Outcomes Of Aggression Replacement Training For U.S. Adolescents In Residential Facilities, Coral Ann Ondrus

Walden Dissertations and Doctoral Studies

A National Survey indicated that 1.6 million adolescents in the U.S. were arrested in 2010 and 1.5 million in 2011 for erratic aggressive behaviors, thus showing a decline from the 2.18 million adolescent arrests in 2007. Residential facilities in the state of Pennsylvania offer a group intervention called Aggression Replacement Training (ART) to help adjudicated adolescents regain control of erratic behaviors. The purpose of this study was to examine the extent to which level of group participation in ART and certain demographic factors (age, gender, ethnicity, family socioeconomic status, parental involvement, and education) predict decreased aggression and increased anger control …

Examining How Knowledge Managers Facilitate The Process Of Knowledge Creation In Organizations, Dean Allen Call

Walden Dissertations and Doctoral Studies

The problem addressed in this study was how knowledge managers facilitated the process of knowledge creation. Researchers identified this area as important because it begins to fill the literature gap in the dynamics surrounding knowledge creation. Using 4 research questions developed from the theory of dynamic organizational knowledge creation, the study investigated how knowledge managers facilitated and supported knowledge creation, promoted knowledge formation, and accounted for knowledge gaps. The theory was selected to provide a framework and an analytical perspective on the process of knowledge creation. A qualitative research design was used to learn from a sample of 12 Chief …

Examining The Relationship Between Emotional Intelligence And Interpersonal Forgiveness Among Internet Users, Noelle Lowry

Walden Dissertations and Doctoral Studies

Emotional Intelligence (EI) and forgiveness both involve interpreting emotional content. Empirical study of a relationship between these two constructs is lacking. This is a problem as many psychological studies infer a relationship between these two constructs. The purposes of this study were to explore whether EI and forgiveness are correlated and to identify whether predictor variables (empathy, life satisfaction, emotional management, and emotional understanding) contribute to the probability of forgiveness within an interpersonal relationship. A quantitative, nonexperimental research design, based on the theory of mind, was used to answer two research questions: Does a correlational relationship exist between the two …

Effects Of A Positive Psychological Intervention On Happiness In At-Risk Students, Pamela Harlan

Walden Dissertations and Doctoral Studies

Researchers have suggested an increased focus on positive psychological interventions to enhance college students' happiness levels; however, few studies have addressed positive interventions on at-risk college students. Based on the theoretical framework of positive psychology and impact of positive exercises on happiness, this study addressed whether a positive intervention would increase happiness as evidenced by scores on the Satisfaction with Life Scale (SWLS) and the Positive and Negative Affect Scale (PANAS). The experimental design included random group assignment and pre- and posttest surveys to collect data from 135 at-risk community college students in Southeast Texas. The experimental group participated in …

Adult Development Of Positive Personality Traits Through Character Formation Mentoring, Robert Mark Colborn

Walden Dissertations and Doctoral Studies

Positive psychologists have published hundreds of empirical studies correlating positive personality traits with improved outcomes in mental health, physical health, academic and career success, resilience, relationships, and personal happiness. But there remains a dearth of research on the emergence and development of positive personality traits. This grounded theory, qualitative research sought to discover whether positive personality traits can be developed in adult mentoring relationships. Sixteen participants responded in structured interviews about the benefits of their mentoring experiences, and in addition to performing coding analysis as described by Strauss and Corbin (1990), the researcher also compared the answers to Peterson and …

Comparative Memory/Behavioral Symptoms Of Alzheimer's Disease: Eoad Vs. Load, Marcia Gale Roberson

Walden Dissertations and Doctoral Studies

Alzheimer's disease (AD) is a fatal disorder with no apparent cure. Early-onset AD (EOAD) occurs in individuals before the age of 65, and late-onset AD (LOAD) occurs in individuals age 65 and older. Past studies have proven that AD is fatal among Americans age 65 and older. The disease is characterized by impairments in memory and executive function as well as other cognitive and behavioral problems. The research questions addressed by this sequential, mixed-method study compared EOAD and LOAD by exploring common behavioral/cognitive symptoms and stage levels of AD. Research participants were recruited from the Alzheimer's Association who were members …

Short Term Memory Of Magnetic Resonance Imaging Technologists, Samuel Maldonado

Walden Dissertations and Doctoral Studies

This study examined the short term memory (STM) difference of magnetic resonance imaging (MRI) technologists versus non-MRI technologists. Human and animal studies have indicated that residual magnetic fields have caused changes within the cerebral structure. Research on residual magnetic fields and their effect on STM is still at its infancy. A quasi-experimental design was used to determine if any significant difference existed between the STM of MRI technologists (n = x) and a control population sample (n = x). The STM of both groups was assessed with the use of the Rivermead Behavioural Memory Test-Third Edition. Solicitation of the participants …

Cortisol Levels And Voltage Conditions Of College Students, Adriana Steffens

Walden Dissertations and Doctoral Studies

There is a limited research base on low voltage brain conditions, which are characterized by electrical activity being measured at below 20 microvolts. The purpose of this study was to examine the relationship between saliva cortisol levels and voltage using an EGG in a college student population. Illuminating this relationship is important to inform how low voltage conditions can affect daily memory and cognitive functioning of undergraduate college students that may be a result of stress. The college student population may be vulnerable to the low voltage condition because of stress from the transition between teenage and adult life and …

Effects Of Mild To Moderate Stress On Mental Rotation, James Frederick Bell

Walden Dissertations and Doctoral Studies

Mental rotation (MR) is the ability to mentally shift one's visual perspective of any object by changing the orientation of a mental image of that object. Research into the effects of stress on MR could be used to help improve understanding of a variety of visual-spatial tasks performed in hyper-vigilance situations. However, until the present study, there has been no research on the effects of stress on MR. The Yerkes-Dodson Law predicts performance will be improved when an individual is exposed to mild to moderate stress. The purpose of this study was to answer three research questions. The questions examined …

Positive Psychological Capital, Need Satisfaction, Performance, And Well-Being In Actors And Stunt People, Brian Hite

Walden Dissertations and Doctoral Studies

Positive psychological capital (PsyCap), a second-order construct formed from optimism, hope, resilience, and self-efficacy, has predicted the performance and psychological well-being of a variety of full-time workers, and mediators of the relationships between PsyCap and performance and psychological well-being have rarely been examined. Using self-determination theory, broaden-and-build theory, and the conceptual framework of positive psychology, this study was an exploration of (a) the relationships among PsyCap, (b) basic psychological need satisfaction (i.e., autonomy, competence, relatedness), and (c) psychological well-being and performance using a sample of 103 working actors and stunt people. A serial mediation model was proposed whereby PsyCap predicted …
