UNLV Theses, Dissertations, Professional Papers, and Capstones

Emotion regulation and emotion processing deficits cut across the varying symptom presentations of schizophrenia. Emotion processing deficits are inadequately treated by pharmacologic interventions and are related to real-world functional impact and disability. This study investigated behavioral and psychophysiological responses to a series of emotion regulation tasks while concurrently collecting eye tracking data as an index of visual attention. A brief neurocognitive assessment was also completed in order to examine potential cognitive determinants of emotion. Participants completed tasks designed to assess cognitive change and directed attention strategies for down-regulation of unpleasant and pleasant emotion. For each of our two unpleasant emotion …

Objective: To evaluate the sex differences in cognitive course over 4 years in Parkinson’s disease (PD) patients with and without mild cognitive impairment (MCI) compared to controls. Methods: Four-year longitudinal cognitive scores of 257 cognitively intact PD, 167 PD-MCI, and 140 controls from the Parkinson’s Progression Markers Initiative were included. Longitudinal scores of men and women, and PD with and without MCI were compared. Results: Women had better verbal memory, men had better visuospatial function. There was no interaction between sex, diagnostic group, and/or time (4-year follow-up period). Conclusions: Sex differences in cognitive course in de novo PD are similar …

University Author Recognition Bibliography: 2019

Introduction: Identifying a dose of physical activity (PA) that can improve cognitive function in children has important implications for school-day PA recommendations. Researchers and educators have interest in this link as it relates to both health and academic performance. This study examined the dose-response relationship between PA and improvement in cognition in a sample of fifth and sixth grade students.

Methods: Participants (n = 156) from eight classes each completed two of four different cognitive assessments on an iPad, both before and after exposure to one of four randomized, 10-min PA conditions (sedentary, light, moderate, and vigorous). Conditions …
