A Comparison Of Teleneuropsychological And Traditional Neuropsychological Battery Factor Structures, Alison Datoc

Theses and Dissertations

This study compared the factor structures of a traditional neuropsychological battery, administered in-person, and a teleneuropsychological battery, administered remotely. Participants were divided into two groups dependent on test condition (i.e., in- person or remote). Individuals in the in-person test condition group (n = 100) were selected from a sample of individuals who were assessed in-person in a previous archival study, and individuals in the remote testing condition group (n = 100) were assessed via teleneuropsychology in their home environment.

Two Exploratory Factor Analyses (EFA) using Principal Component Analysis (PCA) method were conducted on the T-scores and scaled scores of each …

Psychometric Analyses Of A Comprehensive Neuropsychological Battery For Retired Nfl Players, Kimberly Ethridge Fitzgibbon

Theses and Dissertations

This study examined psychometric properties of the NFL Concussion Battery used to examine neuropsychological functioning in retired NFL players who were part of the NFL’s concussion settlement. This battery assesses multiple areas of cognitive functioning; executive functioning, language, processing speed, attention and memory. The study included 117 participants who were male with at least 16 years of education. The sample was 75.9% African-American and average age was 47. All participants completed the entire battery and passed the majority of effort measures. Those that did not pass the majority of effort measures or complete the entire battery were excluded.

T-test analyses …

A Novel Cognitive Stress Test For The Detection Of Early Alzheimer’S Disease In African Americans, Kimberly Capp

Theses and Dissertations

The U.S. population is currently undergoing a major demographic transition, with increasing racial and ethnic diversity of the older adult population. As the growing population of older adults advances in age, memory complaints are projected to increase in prevalence particularly among African Americans and present a challenge to clinicians who must differentiate between normal aging and progressive neurocognitive conditions (Celsis, 2000; Sherwin, 2000). As targeted therapeutic interventions and emerging therapies for AD are much more likely to be effective in the earlier stages of the disease (Loewenstein, Curiel, Duara & Buschke, 2017), early assessment and detection of AD, especially in …

Exploration Of The Wechsler Memory Scale Fourth Edition (Wms-Iv) Designs Content And Spatial Memory Scales, Maya Pinjala

Theses and Dissertations

The Designs subtest was newly added as a measure of visual memory to the Wechsler Memory Scale, 4th edition (WMS-IV). This study examined this measure in a mixed clinical sample (n = 158). Specifically, the aim of the study was to evaluate the publishers’ claims that the Designs test assesses both visual content (“what”) and spatial (“where”) memory, as these functions are processed within distinct neurological systems. To date, no studies have specifically examined the individual Content and Spatial scores in relation to other neuropsychological variables. The purpose of this study was to gain a more comprehensive understanding of the …

Head-Impact-Related Outcomes By Position In Retired Nfl Football Players, Maria Cecilia Boix Braga

Theses and Dissertations

This study examined how repeated head-impact-related traumatic brain injury experienced by retired NFL players impacts their neuropsychological functioning, as well as whether player position was a significant factor in the impairment experienced. Participants (N=142) were selected from an archival database gathered through the NFL Concussion Settlement belonging to the Neuropsychology Assessment Center of Nova Southeastern University.

One-Sample T-Tests indicated that the combined sample and the Skilled players group demonstrated significant differences in all neuropsychological measures, while the Linemen and Skilled Linemen evidenced impairment in most areas except in visual-spatial and non-timed language measures. Two-way ANOVAs indicated player position and ethnicity …

An Analysis And Comparison Of Wms-Iii And Wms-Iv Verbal Paired Associates: Practical Implications For Neuropsychologists, Anthony Paul Andrews

Theses and Dissertations

The current study examined the performance of clinical outpatients on the Verbal Paired Associates (VPA) subtest from current and prior versions of the Wechsler Memory Scale (WMS). It was predicted that VPA from the WMS-III (VPA3) would be similar in agreement to the WMS-IV (VPA4) and that VPA4 would show a stronger relationship than VPA3 with intellectual abilities, sustained attention, and executive function abilities as assessed by the WAIS-IV; CPT-2; and the TMT, Category Test, and Stroop, respectively. Thirty-six adults were administered both the WMS-III and the WMS-IV, along with the other measures as part of a larger neuropsychological battery. …

Age Related Decline In Memory: Examining The Mediation Effect Of Processing, Executive Functioning And Intelligence In Normal Adults, Jada J. Stewart

Theses and Dissertations

Multiple mediation analyses that collectively examine the prominent theories of cognitive aging (i.e., Common Cause, Processing, and Executive Decline Hypotheses) along with other cognitive domains that are sensitive to aging are rare. Moreover, having identified that cognition begins to decline as early as 30 years old, few studies have examined the mechanisms that underlie memory change among younger aging individuals. As a result, it is unclear whether relevant mediating variables have been excluded from early research on age-related memory decline, or to what extent rehabilitative strategies are applicable as early interventions for maintaining cognitive functioning into late life.
