Socioeconomically Disadvantaged Neighborhoods, Stroke Risk, And Cognition In Older Adults: A Focus On Violent Crime, Linda D. Ruiz
Socioeconomically Disadvantaged Neighborhoods, Stroke Risk, And Cognition In Older Adults: A Focus On Violent Crime, Linda D. Ruiz
College of Science and Health Theses and Dissertations
Living in socioeconomically disadvantaged neighborhoods, i.e., neighborhoods with lower incomes, lower education/occupational levels, and/or higher crime, increases one’s risk of developing chronic health problems, including cardiovascular disease risk factors and stroke. These health problems are associated with reduced cognition and dementia and may help to explain disparities in brain aging. We investigated the association of neighborhood socioeconomic characteristics on stroke risk and cognitive outcomes hypothesizing that stroke risk mediates the association between the socioeconomic environment and cognitive functioning. Participants were non-demented community-dwelling older adults (N=121), ~67 years of age (50% male, 44% non-Latino Black) who underwent cognitive and medical assessments. …
A Computational Cognitive Architecture For Exploring Team Mental Models, Neil Benoit Outland
A Computational Cognitive Architecture For Exploring Team Mental Models, Neil Benoit Outland
College of Science and Health Theses and Dissertations
Team Mental Models (TMM) are one of the strongest predictors of team behavior and performance. TMM direct team behaviors through the series of tasks they perform over time. Research in the area, although crucial in demonstrating the effect of TMM, has been largely static, failing to articulate specifically how TMM emerge or function in teams over time. This dissertation develops a computational model to explicate the process of TMM emergence and demonstrate necessary factors. First, I explain the core concepts of TMM emergence, including team composition, dyadic interactions, and contextual variables. Second, I develop a process-oriented theory of TMM development …
Cooperation And Facets Of Psychological Collectivism As Antecedents Of Team Mental Model Similarity, Neal Benoit Outland
Cooperation And Facets Of Psychological Collectivism As Antecedents Of Team Mental Model Similarity, Neal Benoit Outland
College of Science and Health Theses and Dissertations
This thesis investigated the role of facets of trait psychological collectivism (Preference, Reliance, Concern, and Goal-Priority) and the personality trait cooperativeness in the development of Team Mental Models. Team Mental Models (TMMs) are shared representations of a work team’s context that aid a team in directing behaviors and coordinating actions. I utilized Marks, Mathieu, and Zaccaro’s (2001) taxonomy of team processes to explicate and test a model detailing the role of composition in TMM development. Data were collected from 35 teams of 5 individuals who completed a computer simulation in which the team interdependently replicated pictures using blocks. Multiple regression …
