The Phenomenon Of Abstract Cognition Among Scholastic Chess Participants: A Case Study, Brent C. Laws Dec 2014

The Phenomenon Of Abstract Cognition Among Scholastic Chess Participants: A Case Study, Brent C. Laws

Electronic Theses and Dissertations

A qualitative investigation was conducted to explore the phenomenon of abstract cognition among a purposive sample of 5 secondary scholastic chess club participants. The case study enabled the researcher to explore the faculties of abstract cognition among students of contrasting skills and abilities in playing chess. The study also allowed for the consideration of potential visual-spatial, logical, academic, social competency and life benefits of chess play. Through analysis of interviews, chess simulations, blindfold chess play, and narration of chess lines and sequences, the investigator was able to extract meaning and code schemata into a holistic understanding of the phenomenon of …

Blue Is In The Eye Of The Beholder: A Cross Cultural Study On Color Perception And Memory, Mark Douglas Lowry Oct 2014

Blue Is In The Eye Of The Beholder: A Cross Cultural Study On Color Perception And Memory, Mark Douglas Lowry

USF Tampa Graduate Theses and Dissertations

According the linguistic relativity hypothesis, the language one speaks affects how one thinks. Because languages differ in how they categorize color, linguistic relativity has often been tested by conducting experiments on color perception and memory. This study examines the linguistic relativity hypothesis using ecologically valid stimuli: pictures of eyes. Because Russian-speakers are more likely to describe blue/grey eyes as grey, whereas English speakers are more likely to describe them as blue, English and Russian participants were asked to match the overall color of blue eyes to a color scale. There were three conditions. In the first condition (perception), participants saw …

Age-Related Aspects Of Mirror-Use By Bottlenose Dolphins (Tursiops Truncatus), Rachel A. Morrison Oct 2014

Age-Related Aspects Of Mirror-Use By Bottlenose Dolphins (Tursiops Truncatus), Rachel A. Morrison

Dissertations, Theses, and Capstone Projects

Bottlenose dolphins are neuroanatomically different and evolutionarily divergent from primates yet they exhibit mirror self-recognition (MSR), a rare cognitive ability in non-human animals. This research investigated the developmental and age-related aspects of MSR in this species. During a longitudinal study, a social group of bottlenose dolphins at the National Aquarium, Baltimore, MD were exposed to a mirror and their behavioral responses were recorded to: 1) further confirm the presence of MSR in this species, 2) determine the age of emergence of MSR and 3) draw comparisons with data documenting the emergence of this ability in humans and great ape species. …

Cognitive Function In The Alcohol Addiction Treatment Population, Suranee Abeyesinhe Sep 2014

Cognitive Function In The Alcohol Addiction Treatment Population, Suranee Abeyesinhe

Loma Linda University Electronic Theses, Dissertations & Projects

Chronic alcohol abuse has been linked to several cognitive deficits, such as problems with spatial processing, decreased executive functioning, impaired verbal fluency, poor working memory, response inhibition, and social problems such as aggression and social deviance. In order for patients to benefit from treatment, they must be able to utilize multiple cognitive functions. Research has shown that patients suffering from cognitive impairments are much more likely to drop out of treatment early, thereby lending them to higher relapse rates. This study aimed to identify cognitive deficits present in the alcohol addiction treatment population, demographic factors associated with higher levels of …

Dual Task Interference In Low-Level Abilities: The Role Of Working Memory And Effects Of Mathematics Anxiety, Alex Michael Moore Aug 2014

Dual Task Interference In Low-Level Abilities: The Role Of Working Memory And Effects Of Mathematics Anxiety, Alex Michael Moore

UNLV Theses, Dissertations, Professional Papers, and Capstones

Mathematics anxiety is a negative affective reaction to situations involving mathematical thought and is commonly believed to reduce cognitive functioning by impairing the efficient use of working memory resources. The conventional theory describes that the processing disadvantage associated with high levels of math anxiety increasingly impairs performance as working memory demands increase in a math task. Despite this convention, recent reports demonstrate that the high math anxious disadvantage can be measured in tasks that are relatively free of working memory assistance (Maloney, Ansari, & Fugelang, 2011; Maloney, Risko, Ansari, & Fugelsang, 2010). The present study examines these relatively low level …

Cognitive Function Following Bubble-Contrast Transcranial Doppler For Evaluation Of Right-To-Left Shunt, Erin Elizabeth Krauskopf Jul 2014

Cognitive Function Following Bubble-Contrast Transcranial Doppler For Evaluation Of Right-To-Left Shunt, Erin Elizabeth Krauskopf

Theses and Dissertations

Background: Stroke is a leading cause of significant physical, cognitive, and psychiatric morbidity. One risk factor for stroke is paradoxical embolization through a patent foramen ovale (PFO). In cardiac clinical practice, power M-mode Transcranial Doppler (TCD) evaluation is the gold standard for diagnosis of PFO, or right-to-left cardiac shunt (RLS). Brain micro-embolization due to diagnostic bubble contrast echocardiography may cause neurological symptoms in patients with PFO. However, the neurocognitive effects of TCD have not been studied. Objective: The purpose of this study was to evaluate cognitive outcomes in patients who undergo routine diagnostic bubble contrast TCD. The aims of the …

Cisgenderism In Gender Attributions: The Ways In Which Social, Cognitive, And Individual Factors Predict Misgendering, Erica Jayne Friedman Jun 2014

Cisgenderism In Gender Attributions: The Ways In Which Social, Cognitive, And Individual Factors Predict Misgendering, Erica Jayne Friedman

Dissertations, Theses, and Capstone Projects

The current program of research investigated the ways in which social representations of gender, cognitive processes, and individual factors can be integrated to predict "misgendering," an example of cisgenderism in which people are categorized as a gender with which they do not identify. I proposed an (In)consistency Processing Model of Gender Attribution in which perceivers make a gender attribution by interpreting the stereotype-(in)consistencies of a target's gender characteristics through either a biology- or identity-based schema. Five studies were conducted to test different aspects of this model, the first of which was a secondary data analysis on a sample of students …

Assessing Executive Function As It Relates To Self-Regulation, Sarah K. Finley May 2014

Assessing Executive Function As It Relates To Self-Regulation, Sarah K. Finley

Masters Theses and Doctoral Dissertations

Slips of action are cognitive errors that occur during routine tasks in everyday life (Clark, Parakh, Smilek, & Roy, 2012). Minimizing these everyday errors involves executive function, a system of complementary cognitive processes that enable control over thoughts and actions, including attention, inhibition, cognitive switching, and maintaining and manipulating the contents of working memory (Norman & Shallice, 2000). Many aspects of executive function are necessary for self-regulation, or the management of habitual, dominant, prepotent responses (Hamilton, Vohs, Sellier, & Meyvis, 2011). The present study explored the relationship between self-regulation, using self-report questionnaires, and executive function, using task-based assessments. Greater self-regulatory …

Effects Of Perceptual Fluency On Reasoning And Pupil Dilation, Juan Diego Guevara Pinto Apr 2014

Effects Of Perceptual Fluency On Reasoning And Pupil Dilation, Juan Diego Guevara Pinto

Honors College Theses

Research on perceptual disfluency has examined the effects of perceptually demanding stimuli on information processing and reasoning, suggesting that disfluent stimuli elicit slower and more effortful processing. Recent criticism of perceptual disfluency, however, suggests that the effects disfluent stimuli have on processing are marginal, and that they are mediated by individual differences. Participants completed a computerized reasoning task presented in either a fluent (i.e., easy-to-read font) or disfluent format (i.e., hard-to-read font) while pupil diameter was measured by an eye-tracker system. Pupillometry is an established reliable measure of mental activity that reflects differences in cognitive load. Results showed no performance …

Changes In Cerebral White Matter, Vascular Risk And Cognition Across The Adult Lifespan, Andrew Robert Bender Jan 2014

Changes In Cerebral White Matter, Vascular Risk And Cognition Across The Adult Lifespan, Andrew Robert Bender

Wayne State University Dissertations

Numerous studies over the past decade have used diffusion tensor imaging (DTI) to examine associations between age, diffusion and anisotropy measures of cerebral white matter (WM), and cognitive performance. However, few have examined relationships between intra-individual change in DTI measures of WM and cognitive function. It is possible that the extant cross-sectional findings are a poor representation of age-related change in WM and cognition. The present study used latent difference-score modeling (LDM) to assess change over two years in DTI indices fractional anisotropy (FA), radial diffusivity (DR), axial diffusivity (DA) and mean diffusivity (MD). In addition, we examined the effects …

Development And Validation Of The Anterior Cruciate Ligament Injury-Risk-Estimation Quiz (Acl-Iq), Erich J. Petushek Jan 2014

Development And Validation Of The Anterior Cruciate Ligament Injury-Risk-Estimation Quiz (Acl-Iq), Erich J. Petushek

Dissertations, Master's Theses and Master's Reports - Open

Over 2 million Anterior Cruciate Ligament (ACL) injuries occur annually worldwide resulting in considerable economic and health burdens (e.g., suffering, surgery, loss of function, risk for re-injury, and osteoarthritis). Current screening methods are effective but they generally rely on expensive and time-consuming biomechanical movement analysis, and thus are impractical solutions. In this dissertation, I report on a series of studies that begins to investigate one potentially efficient alternative to biomechanical screening, namely skilled observational risk assessment (e.g., having experts estimate risk based on observations of athletes movements). Specifically, in Study 1 I discovered that ACL injury risk can be accurately …

The Effectiveness Of The Concordance-Discordance Model: Identifying Learning Disabilities In School-Aged Children, Bryan Hendricks Jan 2014

The Effectiveness Of The Concordance-Discordance Model: Identifying Learning Disabilities In School-Aged Children, Bryan Hendricks

PCOM Psychology Dissertations

After the reauthorization of Individuals with Disabilities Education Act (IDEA) in
2004, the federal regulations indicated that there are three possible methods for the identification of a Specific Learning Disability (SLD). The three methods include the ability-achievement discrepancy (AAD), Response to Intervention (RTI), and the addition of a third method, which consists of other alternative research-based procedures. Hale and Fiorello (2004) proposed the use of a Concordance-Discordance Model (CDM), which suggests that learning disabled students have discordance between processing strength and both processing weakness and achievement deficit. In addition, SLD students have a concordance between the achievement deficit and processing …

Anxiety Disorders And School-Based Treatments: Assessing School Pyschologists' Knowledge And Perceptions, Kelly A. Myhasuk Jan 2014

Anxiety Disorders And School-Based Treatments: Assessing School Pyschologists' Knowledge And Perceptions, Kelly A. Myhasuk

PCOM Psychology Dissertations

Anxiety disorders are common in children and youth. Despite high prevalence rates, most children with anxiety disorders do not receive treatment. In fact, for the few children who are receiving treatment, schools are the primary source of mental health care. When left untreated, children experience significant disruptions in their academic, social, emotional, and behavioral functioning. Therefore, it is important for those working in schools to recognize and treat children with anxiety disorders. The present study surveyed school psychologists (n = 178) to assess their knowledge about anxiety disorders and about empirically supported school-based treatments. Also, this study sought to investigate …

Testing A Structural Equation Model Of Language-Based Cognitive Fitness, Elizabeth Ann Moxley-Paquette Jan 2014

Testing A Structural Equation Model Of Language-Based Cognitive Fitness, Elizabeth Ann Moxley-Paquette

Walden Dissertations and Doctoral Studies

The normative development of language is often taken for granted, yet problems with language development can result in stress for the individual and family. A challenge with these language development problems lies within the contemporary education system, which assumes that children have appropriate skills when they begin school. The purpose of the study was to test a theoretical model of language readiness known as language-based cognitive fitness, which includes measures associated with structural concepts of language involving receptive language, expressive language, spontaneous narrative speech, and writing fluency. The sample included children from a private school who received an extensive battery …

Proprioception And Literacy In The Digital Realm, Paul Michael Rappoccio Jan 2014

Proprioception And Literacy In The Digital Realm, Paul Michael Rappoccio

Legacy Theses & Dissertations (2009 - 2024)

Drawing on research in the fields of neuroscience, reading cognition, and the history of writing, the author explores the condition of reading today. Rather than accepting the apocalyptic pronouncements that the Internet is "dumbing down" current readers, the author argues for a more nuanced understanding of the effects of digital media. He argues that the literacies needed for the new digital realm are not new, but are literacies developed over thousands of years. The author argues for the need of more education and instruction in the use of digital media, and that the digital realm requires new proprioceptive (spatial awareness) …

Inattentional Blindness And Auditory Attention: Effects Of Cognitive Load On Visual Awareness, Dillon James Cornett Jan 2014

Inattentional Blindness And Auditory Attention: Effects Of Cognitive Load On Visual Awareness, Dillon James Cornett

LSU Master's Theses

The current study investigated the effects of cognitive load, in the presence or absence of distractors, during a dynamic inattentional blindness (IB) task on IB rate. IB is a phenomenon where one fails to notice an unexpected object (UEO) or event (UEE) that is in full view while attention is occupied. In the present study, the presence of distractors was manipulated (present/absent) to investigate the effects of selective attention in inattentional blindness when inhibition of distractors is required or not required. Undergraduates at Louisiana State University completed a visual task while listening to music embedded with sine wave tones (low …

Children's Cognitive Processing Of Abuse As Described In Investigative Interviews., Kayleen A. Willemsen, Kim P. Roberts Jan 2014

Children's Cognitive Processing Of Abuse As Described In Investigative Interviews., Kayleen A. Willemsen, Kim P. Roberts

Theses and Dissertations (Comprehensive)

A great deal of research has examined ways in which investigative interviewers can elicit accurate information from children. More recently, research has studied children’s own thoughts or comprehension of abuse, and how these types of statements relate to disclosure, others’ perceptions of child witnesses, and psychological trauma. However, little research has investigated multiple types of children’s thoughts about abuse as they occur in an actual investigative interview. The current study examined seven types of statements children made about their abuse in a sample of 86 transcripts of investigative interviews conducted by Child Protective Services and a police department in a …
