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 …

Assessing The Impact Of White Noise On Cognition In Individuals With And Without Adhd, Scott Roye
LSU Master's Theses
Although originally viewed only as a childhood disorder, Attention Deficit Hyperactivity Disorder (ADHD) is now recognized to persist into adulthood in many individuals. Adults with ADHD often demonstrate academic, cognitive, and general functioning deficits as a result of their symptoms. Theorists have suggested that features typically associated with ADHD, such as distractibility, excessive motor activity, and executive dysfunction, may stem from being under stimulated at a physiological level. This lack of arousal potentially causes individuals to seek out stimulation, making them more susceptible to background noise and other environmental stimuli. However, previous research primarily focuses on children and adolescents with …
The Relationships Among Emotion, Cognitive Dysfunction And Anosognosia In Huntington’S Disease, Danielle C. Hergert
The Relationships Among Emotion, Cognitive Dysfunction And Anosognosia In Huntington’S Disease, Danielle C. Hergert
USF Tampa Graduate Theses and Dissertations
Huntington's disease (HD) is a genetic, neurodegenerative disorder that is characterized by motor, cognitive and psychiatric disturbances. Anosognosia, or lack of awareness of symptoms, is commonly observed in neurodegenerative disorders, including HD. Most theories suggest that emotion, executive functioning, and memory play important roles in self-awareness. There is limited research of anosognosia in HD and no theoretical model of how it manifests in the disease. The purpose of this study was to examine Metacognitive Knowledge, or overall beliefs about the self, and Online Awareness, or the ability to predict (Anticipatory Awareness) and evaluate (Emergent Awareness) task performance, in …
