Comparative Memory/Behavioral Symptoms Of Alzheimer's Disease: Eoad Vs. Load, Marcia Gale Roberson
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 …
Title: Parents And Teachers’ Perceptions And Clinical Diagnosis Of Autism Among White And Non-White Groups, Margaret Gopaul
Title: Parents And Teachers’ Perceptions And Clinical Diagnosis Of Autism Among White And Non-White Groups, Margaret Gopaul
Walden Dissertations and Doctoral Studies
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, …
Adult Development Of Positive Personality Traits Through Character Formation Mentoring, Robert Mark Colborn
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 …
Short Term Memory Of Magnetic Resonance Imaging Technologists, Samuel Maldonado
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 …
Outcomes Of Aggression Replacement Training For U.S. Adolescents In Residential Facilities, Coral Ann Ondrus
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
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 …
Effects Of A Positive Psychological Intervention On Happiness In At-Risk Students, Pamela Harlan
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 …
Cognitive Processes And Memory Differences In Recall And Recognition In Adults, Laura Elaine Fitzgerald
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
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 …

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