Gait and Cognition: Exploring Cognition and Dual-task Costs in a Group of Community Dwelling Alzheimer’s Disease Patients over 6 Months
DownloadFall 2022
Alzheimer’s disease is a progressive neurological disorder resulting in cognitive decline affecting many activities of daily living including gait. Many tools exist to monitor AD progression, including cognitive examinations, and functional tests of mobility. The purpose of the present study is...

How does the brain represent musical properties? Even with our growing understanding of the cognitive neuroscience of music (Abbott, 2002; Peretz and Zatorre, 2003; Peretz and Zatorre, 2005; Zatorre and McGill, 2005), the answer to this question remains unclear. One method for conceiving possible...

Integrating Characteristics of Executive Functions in Non-Demented Aging: Structure, Trajectories, Classification, and Biomarker Predictors
DownloadSpring 2019
In aging, executive function (EF) performance (level) and change (trajectory) are linked to multiple interacting risk factors. Structurally, EFs have previously been represented as either a unitary (e.g., unidimensional) or diverse (e.g., multidimensional) set of abilities that change across the...

Surprisingly, pigeons have been shown to sacrifice food rewards to get information about the upcoming outcome when making choices in a delay decision task. For instance, when choosing between an option which offers a reward 100% of the time after a delay (e.g. 10 s), versus an option that gives...

NPAS3 encodes a transcription factor of the bHLH-PAS family, which has been robustly associated with neurodevelopmental and psychiatric disorders with intellectual disability as a common feature. NPAS3 was initially discovered as a schizophrenia-associated gene in a family with a translocation...

BACKGROUND. Making one’s own decisions is an important component of autonomy and expression of one’s identity. After an individual has a stroke or other neurological injury, he or she may experience a disruption to their ability to speak, understand, read, and or write (aphasia). Furthermore,...

Surrogate markers of progression in Parkinson disease: Correlation between clinical features and neuroimaging
DownloadSpring 2015
Parkinson disease is a progressive neurodegenerative disorder affecting approximately 100,000 Canadians. Loss of dopaminergic neurons in the substantia nigra of the basal ganglia is the prominent pathology associated with many of the motor features that characterise Parkinson disease. Increased...

Neural Correlates of Emotion-Cognition Interactions in Healthy Functioning and Adolescent Psychopathology
DownloadFall 2015
The current dissertation implemented two large studies involving brain imaging and behavioral methods to expand our current understanding of the impact of emotion on cognition. Study one focused on the immediate and long-term impact of emotion on cognition in healthy functioning. Study two...

Movement ecology thrives from a successful synergy of data and models. In a field where experiments are difficult or impossible, linking field data with mathematical and statistical models allows us to test hypotheses and increase our quantitative understanding of movement processes. Owing to...

The Impact of Computer-based Cognitive Treatment on Language Skills in an Individual with Aphasia
DownloadFall 2014
The cognitive theory of aphasia, which purports that the language impairments found in people with aphasia are due to underlying cognitive impairments, rather than to interruption of linguistic-specific areas of the brain, has been gaining clinical and research interest in recent years. Indeed,...
