Emotional Response To Negative Mood Induction In Mild Cognitive Impairment And Cognitively-Intact Older Adults, Gennarina Diane Santorelli

Doctoral Dissertations

Older adults with mild cognitive impairment (MCI) report greater rates of psychiatric symptoms than cognitively-intact older persons. This may be associated with emotion dysregulation, which is prevalent in cognitively-impaired populations. No research to date has investigated responses to emotionally-provocative stimuli in persons with MCI. Aim 1 of this study determined differences in emotional reactivity to and recovery from negative mood induction in older persons with amnestic MCI (aMCI) and cognitively-healthy older adults. Moreover, emotion dysfunction in MCI may be linked to impairment in executive function (EF), a common feature of MCI. Theoretical models postulate that EF is essential to the …

One Year Change In Cognitive Function In Male And Female Common Marmosets (Callithrix Jacchus), Brianna Healey

Masters Theses

Long term cognitive studies in humans and nonhuman primates such as macaques are difficult because of their long lifespan. The common marmoset (Callithrix jacchus) is a non-human primate who shares with humans many features characteristic of primates, including a complex brain and cognitive function. They also have a short lifespan (~10 years) that makes them a great model in studies of cognitive aging. This study focuses on the rate of decline in cognitive function in male and female marmosets based on performance on reversal learning tasks over 2 years of testing.

We found that marmosets improved their overall …

Aging-In-Community: The Influence Of Social Capital On Accessory-Dwelling Unit Access And Utilization Among Older Americans, Travis M. Gagen

Doctoral Dissertations

Accessory-Dwelling Units (ADUs) are one form of the built-environment in which the field of public health law can intervene to improve population aging. Modifying the built-environment to incorporate ADUs allows older adults to utilize a higher level of smart home technologies (SHT) to age-in-community. Under Massachusetts law MGL c. 40A, the state gives authority to cities and towns to adopt ordinances and bylaws to regulate the use of land, buildings and structures. A mixed-methods research design was used to examine the access and utilization of ADU and SHT among older adults. Of the 351 Massachusetts town and cities, 66.5% were …
