Functional Analysis In The Home Setting Of An Older Adult With Neurocognitive Disorder, Emily Norton
Functional Analysis In The Home Setting Of An Older Adult With Neurocognitive Disorder, Emily Norton
Masters Theses
Currently within the behavioral gerontology literature there are no published studies that include a functional assessment in the home setting. The primary goal of the present study was to address this gap by conducting a functional analysis on a challenging behavior of an older adult with neurocognitive disorder in the home. This study occurred in two phases. During phase one, researchers conducted an antecedent functional analysis on the bizarre speech of an 81-year-old female with suspected dementia across four conditions (television on, no interactions initiated; television on, interactions initiated; television off, no interactions initiated; television off, interactions initiated). Results from …
How Perception Of Decision Environment And Future Information Affects Changes In Delay Discounting Rates: Differences Across U.S. And China, Differences Before And After The U.S. 2018 Midterm Elections, Fran Walsh
Masters Theses
In this thesis, I will explore the idea that choices between present, smaller value options and future, larger value options depend on how much individuals trust the future to deliver the reward. Due to this aspect of trust, the individual must build their estimate of trust based on information for their present environment and their future expectations. This estimate of future trust can change across different time points in the same environment (i.e., before and after a national election) and between environments in the same time point (i.e., between two countries experiencing different economic rates of change). In this set …
Changes In Color Guidance Over The Course Of A Complex Visual Search, Ryan Papargiris
Changes In Color Guidance Over The Course Of A Complex Visual Search, Ryan Papargiris
Masters Theses
When searching for an object, we store a mental representation of the target, which guides our search through the use of attention. The effectiveness of this search guidance varies depending on the task and the relationship between target and distractors. With a better understanding of how search guidance changes over time within a trial, we can better compare the differences between experimental conditions. Eye tracking data from a variety of search tasks were analyzed to determine how color guidance varied over the course of the trial. Color guidance for a given fixation was evaluated based on the distance in color …
One Year Change In Cognitive Function In Male And Female Common Marmosets (Callithrix Jacchus), Brianna Healey
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 …
Does Lactobacillus Reuteri Probiotic Treatment Improve Sleep Quality In Rhesus Macaques (Macaca Mulatta) Displaying The Self-Injurious Phenotype?, Peter Mcginn
Masters Theses
Self-injurious behavior (SIB) is a complex phenotype that occurs with an increasing prevalence of about 7-34% in humans and 10-12% in non-human primates (NHPs). This study evaluated the efficacy of probiotic Lactobacillus reuteri as a treatment for self-injurious behavior (SIB) and sleep disruption in rhesus macaques. The treatment was proposed to alleviate mild self-biting, sleep disruption, and reduce chronically elevated hypothalamic-pituitary-adrenocortical (HPA) axis activity, all hallmark features of monkeys with this condition. The probiotic preparation included two strains of L. reuteri (L. reuteri ATCC PTA 6475 & L. reuteri DSM 17938) containing on average 200 million colony forming units …
