Age Differences In Long-Term Adjustment And Psychosocial Outcomes In A Large Multi-Site Sample 5-10 Years After Heart Transplant, Andrea Shamaskin
Age Differences In Long-Term Adjustment And Psychosocial Outcomes In A Large Multi-Site Sample 5-10 Years After Heart Transplant, Andrea Shamaskin
Theses and Dissertations
Research on age differences in heart transplant patients has focused primarily on medical outcomes, with mixed findings regarding mortality and morbidity rates and limited research regarding age differences in psychosocial and quality of life outcomes. To gain a more complete understanding of psychosocial adjustment after heart transplant, this study examined age differences in: satisfaction with quality of life, satisfaction with social support, depressive symptoms, negative affect, symptom distress, stress related to heart transplant, overall health functioning, coping strategies, and aspects of adherence. Results indicate that older patients, compared to younger patients, report better adjustment and quality of life across numerous …
Comprehending Synthetic Speech Personal And Production Influences, Jingjing Wang-Costello
Comprehending Synthetic Speech Personal And Production Influences, Jingjing Wang-Costello
Electronic Theses and Dissertations
With the increasing prevalence of voice-production technology across societies, clear comprehension while listening to synthetic speech is an obvious goal. Common human factors influences include the listener‟s language familiarity and age. Production factors include the speaking rate and clarity. This study investigated the speaking comprehension performance of younger and older adults who learned English as their first or second language. Presentations varied by the rate of delivery in words per minute (wpm) and in two forms, synthetic or natural speech. The results showed that younger adults had significantly higher comprehension performance than older adults. English as First Language (EFL) participants …
Neural Activity, Neural Connectivity, And The Processing Of Emotionally-Valenced Information In Older Adults: Links With Life Satisfaction, Robert J. Waldinger, Elizabeth A. Kensinger, Marc S. Schulz
Neural Activity, Neural Connectivity, And The Processing Of Emotionally-Valenced Information In Older Adults: Links With Life Satisfaction, Robert J. Waldinger, Elizabeth A. Kensinger, Marc S. Schulz
Psychology Faculty Research and Scholarship
This study examines whether differences in late-life well-being are linked to how older adults encode emotionally-valenced information. Using fMRI with 39 older adults varying in life satisfaction, we examined how viewing positive and negative images affected activation and connectivity of an emotion-processing network. Participants engaged most regions within this network more robustly for positive than for negative images, but within the PFC this effect was moderated by life satisfaction, with individuals higher in satisfaction showing lower levels of activity during the processing of positive images. Participants high in satisfaction showed stronger correlations among network regions – particularly between the amygdala …
The Canine Sand Maze: An Appetitive Spatial Memory Paradigm Sensitive To Age-Related Change In Dogs, Hannah Salvin, Paul D. Mcgreevy, Perminder S. Sachdev, Michael Valenzuela
The Canine Sand Maze: An Appetitive Spatial Memory Paradigm Sensitive To Age-Related Change In Dogs, Hannah Salvin, Paul D. Mcgreevy, Perminder S. Sachdev, Michael Valenzuela
Spatial Cognition Collection
Aged dogs exhibit a spectrum of cognitive abilities including a syndrome similar to Alzheimer's disease. A major impediment to research so far has been the lack of a quick and accurate test of visuospatial memory appropriate for community-based animals. We therefore report on the development and validation of the Canine Sand Maze. A 4.5-m-diameter circular pool was filled with a sand and powdered food reward mix to a depth of 10 cm. Dogs were given 4 habituation and 16 learning trials which alternated a food reward being half (control trials) or fully-buried (acquisition trials) in a fixed location. After a …
Ovarian Hormones, Aging And Stress On Hippocampal Synaptic Plasticity, Michael R. Foy
Ovarian Hormones, Aging And Stress On Hippocampal Synaptic Plasticity, Michael R. Foy
Psychological Science Faculty Works
The ovarian steroid hormones estradiol and progesterone regulate a wide variety of non-reproductive functions in the central nervous system by interacting with molecular and cellular processes. A growing literature from studies using rodent models suggests that 17β-estradiol, the most potent of the biologically relevant estrogens, enhances synaptic transmission and the magnitude of long-term potentiation recorded from in vitro hippocampal slices. In contrast, progesterone has been shown to decrease synaptic transmission and reduce hippocampal long-term potentiation in this model system. Hippocampal long-term depression, another form of synaptic plasticity, occurs more prominently in slices from aged rats. A decrease in long-term potentiation …
Healthy Aging And Self-Objectification The Impact Of Empowerment And Feminist Attitudes On Body Image, Eating Behavior, And Aging Satisfaction, Karen P. Grippo
Healthy Aging And Self-Objectification The Impact Of Empowerment And Feminist Attitudes On Body Image, Eating Behavior, And Aging Satisfaction, Karen P. Grippo
Electronic Theses and Dissertations
The purpose of this study was to contribute to women’s healthy aging across the adult lifespan by empirically examining potential protective factors (e.g., empowerment and feminist attitudes) in maintaining positive body image, healthy eating behavior, and aging satisfaction. Objectification Theory (Fredrickson & Roberts, 1997) provided a theoretical framework for understanding the connections between sexual-objectification experiences, media influences, and self-objectification, and the resulting negative psychological consequences for women in Western society. This study was the first to examine empowerment in relation to Objectification Theory. Additionally, a developmental perspective was gained by using a diverse sample of young, middle-aged, and older women …
