Background. Context use in sentence comprehension is fairly resistant to age-related cognitive decline; however, event-related potentials (ERPs) studies have shown age effects in neural activity associated with sentence comprehension, specifically when contextual information is manipulated. One...

Older Adults and Generativity: Developmental, Experimental, and Clinical Advances in Terror Management Theory
DownloadSpring 2013
Terror Management Theory (TMT) (Greenberg, Pyszczynski, & Solomon, 1986) offers an empirical framework to explore how human beings function despite their fear of death. TMT studies have shown that in order to buffer death anxiety, people strive to meet the standards of their cultural worldview. ...

Narratives of King Solomon’s life and reign are preserved in both the Book of Kings and the Book of Chronicles, and both texts contain similar narrative elements and mnemonic constructions, such as Solomon’s role as Temple builder and his great wisdom. Other elements of the narrative have been...

Role of Caregiver Beliefs About Alzheimer Disease in the Social Creation of Dependency Among Persons With Alzheimer Disease
DownloadFall 2012
It is estimated that over 1.1 million people in Canada will have dementia by 2038 (Alzheimer Society of Canada, 2010). In the caregiving context it is important that independence be maintained for as long as possible. Previous research has shown that caregivers can inadvertently create excess...

Selected Health Factors (Pulse Pressure, Type 2 Diabetes) and Genetic Polymorphisms (ApoE, IDE rs6583817) Play Independent and Interactive Roles in Patterns of Cognitive Performance and Change in Older Adults
DownloadSpring 2014
Objective: This gene x environment (health) dissertation focused on concurrent and longitudinal change in performance on executive function (EF) and declarative memory (DM) latent variables by normal aging adults. Specifically, we report three studies that tested the independent and interactive...

Fall 2016
Apolipoprotein E (APOE) ɛ4 and Clusterin (CLU) C alleles are risk factors for Alzheimer’s disease (AD) and preclinical cognitive and memory decline in older adults. We investigated whether memory resilience to genetic risk (i.e., Apolipoprotein E [APOE] ɛ4, Clusterin [CLU] CC, and a high additive...

Skeletal Muscle Sympathetic Vasoconstrictor Control Following Short-Term Mild- and Heavy-Intensity Exercise Training
DownloadFall 2013
The purpose of this thesis was to investigate the effects of short-term endurance exercise training (ET) on sympathetic vasoconstriction in resting and contracting skeletal muscle. To achieve these aims, rats were exercise trained on a motorized treadmill and an anesthetised whole animal in situ...

Stroke Prevention in Middle-Aged and Older Arab Immigrant Women: Emphasizing Strengths and Identifying Challenges
DownloadFall 2017
Arab immigrants constitute a minority group that is increasing in Canada. Minimal literature exists on Arab immigrant women’s experiences of ageing while managing health concerns. The evidence suggests that stroke risk factors are on the rise in this population with a lack of supportive resources...

Structural changes of the amygdala subnuclei and limbic white matter tracts in healthy aging and major depressive disorder
DownloadFall 2019
The world population is dramatically aging. Several factors affect brain in healthy aging. The apolipoprotein E (APOE), brain-derived neurotrophic factor (BDNF) and catechol-O-methyl transferase (COMT) might be involved in neurodegenerative diseases, depression and cognitive decline in healthy...

Synergistic Associations of Genetic, Demographic, Health, and Lifestyle Risk Factors on Neurocognitive Performance and Change in Aging
DownloadSpring 2016
Objective: Neurocognitive phenotypes observed in aging have been linked to select combinations of candidate genetic polymorphisms and modifiable risk factors. In this dissertation, I test multiple methods and approaches to examine three modifiable risk domains (i.e., demographic, health,...
