You Hurt My Feelings: Autonomic And Behavioral Responses To Social Exclusion And The Moderating Effect Of Psychopathic Traits, Liat Kofler
Dissertations, Theses, and Capstone Projects
Humans have a fundamental need to form and maintain social connections, and thus experiencing social exclusion is extremely distressing as it threatens this basic human need. Individuals who are socially excluded often respond aggressively, not only towards their ostracizers but also towards innocent bystanders, with ostracism being implicated in extreme acts of violence such as school shootings. However, individual differences in behavior exist within the context of social exclusion as not everyone responds aggressively after being ostracized. Identifying risk factors for retaliatory aggressive behavior following experiences of social exclusion may facilitate the development of targeted interventions aimed at mitigating such …
Brainwaves, Memory, And Reward, Rebecca Mccune
Brainwaves, Memory, And Reward, Rebecca Mccune
Dissertations, Theses, and Capstone Projects
The development of effective educational curricula for enhancing learning involves the crucial consideration of effort and rewards. In the realm of education, teachers commonly employ rewards as motivational tools. Traditionally, these rewards are given to students as a recognition of their successful performance. However, a thought-provoking idea emerges: What if we were to extend rewards to students not solely based on accurate answers, but also on the effort they invest, even in cases where their actual response might be incorrect? Our study explores the potential impact of this approach on the way information is absorbed and subsequently retained, specifically focusing …
The Effects Of Music Therapy On Elderly Adults With Dementia, Jeante J. Jackson
The Effects Of Music Therapy On Elderly Adults With Dementia, Jeante J. Jackson
Dissertations, Theses, and Capstone Projects
As people age, the brain is more susceptible to changes that diminish cognitive function. In recent years neuroscience has found convergent evidence between music therapy and brain architecture, as it has shown the generation of new connections in the brain or a reorganization and possible strengthening of existing connections already in the brain. However, the literature regarding music training’s effects on executive control, selective attention, and speech processing is lacking particularly when it comes to older populations.
This study investigated Verbal Working Memory, Visuospatial Attention and Task Initiation, and Auditory Selective Attention in a 91-year-old adult (B.P.) diagnosed with dementia. …
Statistical And Biological Analyses Of Acoustic Signals In Estrildid Finches, Moises Rivera
Statistical And Biological Analyses Of Acoustic Signals In Estrildid Finches, Moises Rivera
Dissertations, Theses, and Capstone Projects
Acoustic communication is a process that involves auditory perception and signal processing. Discrimination and recognition further require cognitive processes and supporting mechanisms in order to successfully identify and appropriately respond to signal senders. Although acoustic communication is common across birds, classical research has largely disregarded the perceptual abilities of perinatal altricial taxa. Chapter 1 reviews the literature of perinatal acoustic stimulation in birds, highlighting the disproportionate focus on precocial birds (e.g., chickens, ducks, quails). The long-held belief that altricial birds were incapable of acoustic perception in ovo was only recently overturned, as researchers began to find behavioral and physiological evidence …
Extraction Of Challenging Forensic Samples Using The Microgem Dna Extraction Kit, Falyn R. Vega
Extraction Of Challenging Forensic Samples Using The Microgem Dna Extraction Kit, Falyn R. Vega
Student Theses
In forensic science, DNA extraction can be a tedious and resource-intensive process. Extraction with Proteinase K is an industry standard but has its drawbacks, such as requiring multiple ionic detergents and washing steps. MicroGEM has developed a new enzyme called forensicGEM that is temperature-dependent and compatible with mesophilic enzymes, offering complete DNA extraction in about 20 minutes in a single tube, limiting contamination, loss of sample, and working time. ForensicGEM can extract DNA from highly degraded samples, potentially leading to more complete STR profiles. Highly degraded tissue and bone samples were collected and extracted with the forensicGEM …
Dendritic Spine Density And Morphology In The Dorsolateral Striatum Following A High Fat Diet, Tikva Nabatian
Dendritic Spine Density And Morphology In The Dorsolateral Striatum Following A High Fat Diet, Tikva Nabatian
Dissertations, Theses, and Capstone Projects
Obesity rates have been dramatically rising in recent years and in 2017-2018 more than 42% of adults in the United States were obese. Obesity is associated with numerous health problems, including cardiovascular disease, stroke, insulin resistance, and type II diabetes. The prevalence of highly palatable and calorically dense foods high in fats and sugars is a significant factor in the increase in obesity rates. Many suggest that palatable food affects the brain in ways similar to drugs of abuse, reinforcing the consumption of highly palatable foods in the same way drugs reinforce drug use. While numerous weight loss programs and …
Analysis Of Electrophysiological Markers And Correlated Components Of Neural Responses To Discourse Coherence, Kurt M. Masiello
Analysis Of Electrophysiological Markers And Correlated Components Of Neural Responses To Discourse Coherence, Kurt M. Masiello
Dissertations, Theses, and Capstone Projects
Constructing meaning from spoken language is invaluable for learning, social interaction, and communication. In clinical populations with developmental disorders of speech comprehension, the severity of disruption can persist and vary from limiting occupational opportunities to lower performance outcomes. Previous research has reported an event-related potential (ERP) neural positivity over right hemisphere lateral anterior sites in response to semantic and discourse processing. Although useful as a marker for clinical populations of autism spectrum disorder (ASD) and developmental language disorder (DLD), little is understood about the dynamics and neural sources of this biological marker. In addition to traditional methods of ERP analysis, …
Civil Society Organizations Serving Children In Vietnam: Opportunities And Constraints Working With Government Agencies, Trang P. Kelly
Civil Society Organizations Serving Children In Vietnam: Opportunities And Constraints Working With Government Agencies, Trang P. Kelly
Dissertations, Theses, and Capstone Projects
When Vietnamese civil society organization (CSO) administrators manage their relationships with government authorities to ensure children receive social services, they operate under Vietnam’s complex political, socioeconomic, and cultural constraints in environments where the Vietnamese government employs soft power to control CSOs and their donors. This study adds to the literature on the nature of CSO in Vietnam. It details the current imbalance of power between state-sponsored organizations (SSOs) and non-SSOs and provides an updated view of how Vietnamese non-SSOs mix social, economic, and political roles as employers and advocates.
Combining a qualitative exploratory and interpretative case study, I address a …
Sit Less, Move More: A National Study Of Physical-Activity Behavior And Cancer, Stella O. Nwogugu
Sit Less, Move More: A National Study Of Physical-Activity Behavior And Cancer, Stella O. Nwogugu
Dissertations, Theses, and Capstone Projects
Background: Physical activity is associated with lower risks of cancer, the second leading cause of death among Americans. Yet, sedentary behavior is the prevailing lifestyle for about 80% of American adults. Additionally, cancer survivors remain significantly inactive, even though physical activity has been shown to decrease risk of cancer and cancer recurrence, improve tolerance of cancer therapy, and reduce mortality. This research explores the relative impact of personal agency, social support, and key demographic variables on physical-activity behavior for a national sample of adults as well as how these relationships differ for cancer survivors and their counterparts.
Methods: Using the …
