Sugar Consumption And Cognitive Aging In The Swedish Adoption/Twin Study Of Aging, Shyam Seetharaman

Graduate Theses and Dissertations

Abstract

Consumption of foods high in sugar content has been linked with the development of metabolic abnormalities such as cardiovascular disease and type II diabetes, major sources of global health concerns. Although the detrimental consequences of high intake of sugar on abnormal metabolic processes are established, it is not known how this association affects (or accelerates) cognitive aging.

The current project was based on data from the Swedish Adoption/Twin Study of Aging (SATSA) to test the hypothesis that high refined sugar intake contributes to accelerated trajectories of cognitive decline assessed longitudinally. Trajectories of cognitive change were assessed as a ...

Semantic Feature Distinctiveness And Frequency, Katherine Marie Lamb

Graduate Theses and Dissertations

An experiment was conducted to examine the importance of semantic feature distinctiveness and feature frequency in accessing the lexical representations of young and older adults in an off-line task using features of animals. The McRae, Cree, Seidenberg, and McNorgan (2005) feature norm corpus ...
