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 …

Examining Reliability And Validity Of The Roadsign Perception Test, Justin Hull Ory
LSU Master's Theses
The Road Sign Perception Test (RSPT) is a newly developed assessment procedure related to driver advisement, and its psychometric properties have not yet been examined systematically. The present study examined the construct validity and the reliability of RSPT measurements. Cronbach’s α and test-retest reliability statistics were completed, as were correlations reflecting on the test’s construct validity. Results indicated that the RSPT possesses marginal test-retest reliability, adequate internal consistency for duration of stimulus presentation and for specific stimuli, but low for number of signs presented. RSPT performance was significantly correlated with convergent variables measuring aspects of attention, working memory, and spatial …
