Nutrition As A Modifiable Risk Factor For Cognitive Decline: Associated Cognitive And Physical Health Changes, Taylor Mcmillan

Electronic Theses and Dissertations

Dementia is defined as gradual, progressive loss of cognitive functioning, greater than what is expected of normal aging, resulting in functional impairment. There are several types of dementia clinical syndromes that are accompanied by unique patterns of cognitive dysfunction and neuropathological changes. Alzheimer’s disease (AD) is the most common type of clinical dementia syndrome, accounting for approximately 60-70% of cases. Neuropathological mechanisms associated with AD include the disruption of the cholinergic system, accumulation of amyloid-beta plaques and hyperphosphorylated tau, as well as vascular pathology. Vascular pathology complicates the characterization of clinical and neuropathic changes in AD, as there becomes significant …

Do Good Things Come To Those Who Wait?: Investigating Temporal Discounting Rates Among Older Adults, Amy Halpin

Electronic Theses and Dissertations

Decision-making is widely viewed as a higher-order cognitive construct, drawing on fluid intelligence as well as intact functioning across a wide variety of cognitive domains including executive function, working memory, declarative memory, and attention.

However, decision-making behavior among and within these contexts remains inconsistent and inconclusive in older adult populations. Considering that recent evidence suggests the …


Oral Contraception And Cognition, Kathleen Gerencer Aug 2023

Oral Contraception And Cognition, Kathleen Gerencer

Electronic Theses and Dissertations

Oral contraception is currently used by over 100 million women worldwide. Women utilize contraception not only to prevent pregnancy but also to manage a wide range of health concerns, such as acne and polycystic ovarian syndrome. Although this medication has granted women bodily autonomy, helped them attain higher levels of education, and helped them enter the workforce in greater numbers, little is known about the consequences outside of the intended contraceptive effects, specifically the cognitive and behavioral consequences. Moreover, because doctors can prescribe contraception after the first menstrual cycle and during puberty, it’s possible that this critical window of development …

Spontaneous Behavioral Coordination: The Impact Of Achieved And Desired Interpersonal Closeness On Synchrony And Mimicry, Morgan Stosic Aug 2023

Spontaneous Behavioral Coordination: The Impact Of Achieved And Desired Interpersonal Closeness On Synchrony And Mimicry, Morgan Stosic

Electronic Theses and Dissertations

The purpose of the present dissertation was to examine the impact of interpersonal closeness and the desire for interpersonal closeness on displays of behavioral synchrony and mimicry, simultaneously. Groups of two strangers (N = 182 participants, N = 91 dyads) were randomly assigned to complete a “closeness-inducing” task where partners took turns asking and answering intimate questions or a comparison “small-talk” task where partners asked and answered less-intimate questions. Additionally, dyads were randomly assigned to complete these tasks in real time over Zoom, or by reading and responding to the task’s questions over text. These tasks were intended to generate …
