An Examination Of The Relationship Between Validity And Memory Measures In Retired Nfl Players, Huda Abu-Suwa

Theses and Dissertations

Neuropsychologists have increasingly become involved in assessing sports-related concussions; however, an important concern is the validity of the evaluations. This study examined the relationship between Performance Validity Tests (PVTs) and memory measures in a comprehensive standardized battery administered to retired NFL players, with the purpose of exploring how predictive PVTs are for memory performance in this population. Hierarchical multiple regression analyses were used to evaluate the relationship between four PVTs (TOMM, MSVT, RDS, and Word Choice) and six memory tasks (WMS-IV LM I and LM II, VPA I and VPA II, VR I and VR II). A regression analysis was …

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. …

Exploration Of The Wechsler Memory Scale Fourth Edition And Measures Of Executive Function Combined Components Model, Isaac Tourgeman

Theses and Dissertations

While memory is the faculty that affords us learning, adaptation and development, it is our executive function that oversees, manages and organizes these abilities. Still, there is limited research on the interaction between memory and executive function. The present study investigated this relationship through Principal Components Analysis. Performances on accepted measures of memory and executive function were evaluated in an adult clinical sample. Components were retained using three criteria: a predetermined four-component structure, eigenvalues exceeding a value of one, and parallel analysis. Results demonstrated that a four-component model most accurately represented the data. Analyses also revealed that measures of immediate …

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.
