Examining Attentional Control And Processing Speed Deficits As Underlying Mechanisms Of Neuropsychological Impairment In Schizophrenia, Mayte Forte
Graduate Masters Theses
Neuropsychological impairment is a key characteristic of schizophrenia (SZ), but its cognitive profile and underlying information processing mechanisms are not yet well understood. We compare patterns of neuropsychological functioning in 85 persons with SZ and 76 healthy controls across measures of intelligence, memory, and executive function. We then test the hypothesis that neuropsychological impairment in SZ is related to dual deficits in two related but distinct information processes: processing speed and attentional control. All research participants completed Wechsler Adult Intelligence Scale-Third Edition (WAIS-III), Wechsler Memory Scale Third Edition (WMS-III), and Wisconsin Card Sorting Test (WCST), all of which provided measures …
Examining The Concurrent And Predictive Relations Of Working Memory In Childhood Attention-Deficit/Hyperactivity Disorder, Ashley N. Simone
Examining The Concurrent And Predictive Relations Of Working Memory In Childhood Attention-Deficit/Hyperactivity Disorder, Ashley N. Simone
Dissertations, Theses, and Capstone Projects
Attention-deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by developmentally inappropriate levels of inattention and/or hyperactivity/impulsivity which lead to impairment in multiple settings (American Psychiatric Association, 2013). Childhood ADHD has been concurrently associated with various neurocognitive deficits and one in particular that has been under examination over the past several years is working memory (WM). WM is a temporary storage system that is responsible for maintenance and/or manipulation of information in order to complete complex cognitive and behavioral tasks. Researchers have postulated that WM is one of several potential endophenotypes of ADHD (Castellanos & Tannock, 2002) and/or that WM is …
Examining The Effects Of Frustration On Working Memory Capacity In An Emerging Adult Sample, Jonathan Parks Fillauer
Examining The Effects Of Frustration On Working Memory Capacity In An Emerging Adult Sample, Jonathan Parks Fillauer
Masters Theses
Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with numerous pejorative outcomes in adults such as low frustration tolerance and deficits in central executive functioning. The present study aims to examine (1) the effect of induced frustration on working memory capacity (WMC) and (2) the unique contribution of ADHD symptoms and other commonly comorbid disorders (i.e., anxiety/depression and alcohol use) to frustration. Participants (N=66) were randomly assigned to either the control group (n=32) or the experimental group (n=34). The Frustration Induction Procedure (FIP) was administered to participants in the experimental group and a neutral, non-frustrating task was administered to a control group. A …
Dual Task Testing Of The Adaptive Combination View In Spatial Reorientation, Donald G. Sullens
Dual Task Testing Of The Adaptive Combination View In Spatial Reorientation, Donald G. Sullens
Electronic Theses and Dissertations
If an organism is trained to approach a location within an enclosure the organism will approach the correct location and it’s geometrically identical location within the environment upon removal of any features. This phenomenon has been turned spatial reorientation, and further studies on how, and to what, organisms reorient have conducted in the last several decades. In the reorientation literature, two theories have surfaced to fill the void left by the rejection of the initial reorientation theory, the Geometric Module theory. I attempt look to discern if the synonym judgement dual task will hinder reorientation in a similar or different …
