The Effect Of A Music-Movement Intervention On Arousal And Cognitive Flexibility In Older Adults With And Without Mild Neurocognitive Disorder, Carolyn Dana Dachinger Nov 2016

The Effect Of A Music-Movement Intervention On Arousal And Cognitive Flexibility In Older Adults With And Without Mild Neurocognitive Disorder, Carolyn Dana Dachinger

Open Access Dissertations

The purpose of this study was to examine the effect of a music-movement intervention (MMI) on cognitive flexibility and arousal in older adults with typical cognitive aging (TCA) or with symptoms of mild neurocognitive disorder (MND). This study also examined the relationships among participants’ demographics, including age, exercise frequency, and years of music participation, and the dependent variables of cognitive flexibility, perceived arousal, physiological arousal, and perceived exertion. Previous research and current theory suggests that multimodal interventions combining simultaneous physical activity and cognitive training may be an effective avenue for enhancing older adults’ cognition. Moreover, theory suggests that participation in …


Impact Of Dance Complexity On Computer-Based And Movement-Based Cognitive Performance, Sean Nicolle Nov 2016

Impact Of Dance Complexity On Computer-Based And Movement-Based Cognitive Performance, Sean Nicolle

Open Access Dissertations

BACKGROUND: Exercise improves cognition, but the specific mechanisms underlying these changes are not clear. Two proposed mechanism are aerobic demand and cognitive demand inherent in varying degrees to specific exercise tasks. This study compared two kinds of dance that differed in instruction complexity and aerobic intensity, ballroom (BR) and aerobic dance (Aero). The primary aim of this study was to determine if the cognitive benefits of exercise are more responsive to the complexity or aerobic overload. METHODS: Fourteen subjects aged 40-80 were randomly assigned to 8 weeks of Aero or BR dance classes. Aero classes were designed to emphasize low …


The Combined Effects Of Acute Exposure To Simulated Altitude And Moderate Intensity Aerobic Exercise On Measures Of Cognition, Laura Q. Jimenez Sep 2016

The Combined Effects Of Acute Exposure To Simulated Altitude And Moderate Intensity Aerobic Exercise On Measures Of Cognition, Laura Q. Jimenez

Open Access Dissertations

The present study was conducted to examine the behavioral cognitive and neurophysiological effects of acute exposure to simulated moderate and high altitudes at rest and during exercise in an effort to delineate whether there is a level of simulated altitude beyond which cognition and neurophysiological function are impaired and whether exercise improves or worsens cognitive function during exposure to simulated altitude. Dependent variables included accuracy and reaction time on a number of behavioral cognitive tasks, and the amplitude and latency of their associated event-related potentials. Fourteen recreationally active college students (M=9, F=5) aged 18-35 participated in this study, which consisted …


Cognitive Complexity In Carnivora: The Evolutionary Link Between Social Complexity And Cognitive Complexity, Natalia D. Borrego Feb 2016

Cognitive Complexity In Carnivora: The Evolutionary Link Between Social Complexity And Cognitive Complexity, Natalia D. Borrego

Open Access Dissertations

Traditional views of cognitive evolution favored a simplistic approach in which the evolution of advanced cognition was considered unique to primate lineages. A recent expansion to non-primates indicates that cognition convergently evolved in several lineages. The social intelligence hypothesis attributes the convergent evolution of cognitive complexity to shared selective pressures imposed by social complexity. According to the social intelligence hypothesis, social individuals benefit from cognitive abilities facilitating social life, and the resultant fitness advantage engenders an evolutionary link, whereby social complexity selectively favors cognitive complexity. The social intelligence hypothesis predicts that social species are cognitively advanced. Although several studies support …
