All Under Control: How Trait Emotional Intelligence May Moderate The Effect Of State Arousal On Implicit Attitudes Towards Academic Dishonesty, Daniel J. Moco
All Under Control: How Trait Emotional Intelligence May Moderate The Effect Of State Arousal On Implicit Attitudes Towards Academic Dishonesty, Daniel J. Moco
West Chester University Master’s Theses
The current study examined predictors in the changing of implicit attitudes toward academic dishonesty (AD). The primary predictor measured was self-reported stress and arousal, the strength of which being a possible influence on one’s change in implicit attitudes. Trait emotional intelligence (EI) was measured as a covariate and potential moderator of the interaction between stress and arousal, and one’s implicit attitudes toward AD. One hundred nine undergraduate psychology students from a public university were recruited to take assessments for trait EI, stress and arousal, and implicit attitudes toward AD. To manipulate the induction of stress and arousal, participants were randomly …
A Comparative Analysis Of Perineuronal Nets In Trout And Zebrafish Models, Adnan Alyan
A Comparative Analysis Of Perineuronal Nets In Trout And Zebrafish Models, Adnan Alyan
Cal Poly Humboldt theses and projects
Perineuronal nets (PNNs) are specialized extracellular matrix structures that surround certain types of neurons in the central nervous system. Research from the past few decades has cemented PNNs as an integral player in the closure and onset of critical periods, memory modulation, and neural plasticity. These effects are thought to occur when PNNs form around a neuron and structurally stabilize its synaptic connections. PNNs have been directly linked to behavioral changes, making them of interest to psychologists as well as neuroscientists. Several PNN components, such as Hapln1 and aggrecan such as have been found in zebrafish, a teleost fish (Kang …

Human Perception Of Ai Capabilities At Classifying Perturbed Roadway Signs, Katherine R. Garcia, Jing Chen, Yanru Xiao, Scott Mishler, Cong Wang, Bin Hu
Psychology Faculty Publications
Artificial Intelligence (AI) is crucial to numerous functions required for driving automation systems, including the computer vision techniques used to detect the roadway environment and make real-time decisions. However, the images used as inputs to the AI system may be maliciously perturbed, or manipulated, causing the AI system to make an incorrect classification. In this study, we examined humans’ perception of the AI’s computer vision capability of classifying various road sign images, including the original images, images with two different types of malicious attacks, and images that are scrambled randomly at the pixel level. Our results showed that participants rated …
Telling Their Story: A Proposed Social Group For Autistic Teenagers, Bailey Hull
Telling Their Story: A Proposed Social Group For Autistic Teenagers, Bailey Hull
Psychology Doctoral Specialization Projects
Typically developing adolescents go through many transitions and learning experiences from ages 13 to 18. Autistic adolescents also develop through these transitions and learning experiences. This unique group of adolescents can have a much more difficult time with these involvements, however, due to societal standards, learning, and growing within a neurodivergent mindset. As social isolation, bullying, and a lack of friendship opportunities continue to persist within the neurodivergent adolescent community, the lack of appropriate, affirming interventions must be addressed. This doctoral specialization project aims to provide licensed and student-level clinicians with a treatment manual to guide them through a social …

Measuring Personality And Animal Treatment Attitudes With The Pet Scale, Zackery J. Hilton
Measuring Personality And Animal Treatment Attitudes With The Pet Scale, Zackery J. Hilton
Honors Undergraduate Theses
Previous research has looked at the association between personality traits and the proclivity, or history, of committing acts that are characterized as animal abuse or animal cruelty. Much research has also found that individuals who exhibit this type of behavior towards animals also tend to exhibit similar behavior towards other individuals, mainly in the form of domestic or child abuse. Previous studies have measured animal abuse using very explicit and extreme criteria, using acts that are without question blatant abuse or torture; however, there is some grey area where many may argue whether certain acts should be considered abuse, which …
Finding Love On The Spectrum: An Analysis Of Social And Romantic Relationships Of Autistic College Students, Kaylee Spinner
Finding Love On The Spectrum: An Analysis Of Social And Romantic Relationships Of Autistic College Students, Kaylee Spinner
Masters Theses
Autism Spectrum Disorder (ASD) is characterized by difficulties in socialization, communication, and developing relationships with others. While many autistic individuals desire to start relationships with others, many do not have a very strong understanding of the use of nonverbal communication or how to develop these connections organically. As autistic individuals have become more open about wanting these resources to form social and romantic relationships, there has been more of a push in the literature to include social skills training for forming social relationships. However, the research on the desire for or development of romantic relationships for autistic individuals is still …

Other liquid characteristics, such as protonated nicotine ratio and sweetener additives, are less understood but may serve as regulatory targets. This clinical laboratory study examined the effects of ENDS protonated nicotine ratio and sweetener presence on nicotine delivery, use behavior, and subjective effects.
Thirteen participants completed four sessions that varied by protonated nicotine ratio (0:100 vs. 40:60 freebase to monoprotonated nicotine) and sweetener status (sweetened with 3 mg/mL ethyl maltol vs. unsweetened). Each session included a …
In Praise Of Dust, Hasler Gomez-Perez
In Praise Of Dust, Hasler Gomez-Perez
Theses and Dissertations
A desire path is a physical manifestation of where a system has failed, but also where it has been refused, where a new path has been made. The wake exists in the post, it is not a singular, untethered event, but a subtle double entendre that lives in the post-death, but also in the pre-life—not a liminal limbo, but a superposition of dying and waking.
This collection was assembled and composed over the course of two years as I navigated my practice, myself, and others. Present here are my thoughts, my experiences, and in many ways my beliefs. IN PRAISE …

Analysis Of Pre-Service Teachers’ Personal Metaphors About Foreign Language Teaching, Juan Luis De La Montaña Conchiña, Guadalupe De La Maya Retamar, Magdalena López-Pérez
Analysis Of Pre-Service Teachers’ Personal Metaphors About Foreign Language Teaching, Juan Luis De La Montaña Conchiña, Guadalupe De La Maya Retamar, Magdalena López-Pérez
Australian Journal of Teacher Education
This study analyses the characterisation and evolution of the personal metaphors of a sample of 34 trainee foreign language teachers, through a questionnaire of open-ended questions that included asking the participants to make drawings representing the roles of the teacher. Four categories of metaphors were considered for the analysis: behaviourist/transmissive, cognitivist/constructivist, situated, and self-referential. The results indicate that most participants were able to conceptualise their image of the teacher in the form of metaphors. The pre-service teachers’ metaphors represented are mainly cognitivist/constructivist and behaviourist/transmissive. When comparing them before and after the internship in the primary schools, most of them did …

Early life adversity has been shown to have a variety of negative effects on adult functioning, including parenting quality, with implications for child wellbeing. Adverse early life experiences including poverty have been linked to long-term disruptions in emotional, cognitive, and physiological functioning that compromise the ability to provide sensitive, nurturing care. The present study investigated whether emotional regulation difficulties, physiological regulation, and cognitive function mediate the relationship between early life financial insecurity and parenting quality. A sample of 132 mother-child dyads completed self-report measures, biological samples, and cognitive assessments. A multiple mediation model ran in SPSS, revealed a significant indirect …
Severe Aggression Among Zoo-Housed Coconut (Trichoglossus Haematodus) And Rainbow (Trichoglossus Moluccanus) Lorikeets: Wellbeing Considerations For Free-Flight Aviaries, Emily Simkins
UNF Graduate Theses and Dissertations
As conservation and education institutions, modern zoos balance the needs of animals with the interests of visitors through several strategies which can increase animal wellbeing and improve visitor experience. Environmental enrichment is frequently employed to increase the suitability of anthropogenic environments for zoo-housed animals, such as through walkthrough habitats and free-flight aviaries. While habitats such as these are important for visitor experience and can be enriching to animals, there are also wellbeing considerations for these spaces. Walkthrough habitats can be a potential source of fear and stress for animals, as shown by increased frequencies of vigilance, undesirable behavior, and aggression. …

PCOM Psychology Dissertations
The global risk of dementia due to longer lifespans and increased medical interventions necessitates accurate diagnosis of cognitive decline. Thus, the utilization of neuropsychological testing to diagnose disorders of cognitive decline should seek to ascertain multiple data, including success/failure of cognitive tasks and evaluation of error patterns. The purpose of this study was to examine the frequency of executive function (EF) errors across diagnoses of cognitive decline (age-related cognitive decline [ARCD], mild cognitive impairment [MCI], vascular dementia [VaD], frontotemporal dementia [FTD], Lewy body dementia [LBD], and Alzheimer’s disease [AD]) and to examine whether the specific types of EF errors (intrusion, …
Examining Factors Considered In Autism Specialization Among Early Career Psychologists, Tarie Taylor
Examining Factors Considered In Autism Specialization Among Early Career Psychologists, Tarie Taylor
PCOM Psychology Dissertations
Families in the United States often face significant delays in accessing autism-related healthcare services. Despite routine autism-specific screenings at 18- and 24-month pediatric visits, there is still, on average, a gap of over two years before families receive an autism diagnosis (Chen et al., 2023). Although the literature cites factors like limited access to specialized providers and a lack of autism-specific services contributing to this delay (Cantor et al., 2020), further research is needed to explore the underlying factors influencing providers' decisions to specialize in an autism-related healthcare service. Thus, the current study used a mixed-methods, internet-based survey to examine …

The Artemis missions will establish a sustainable human presence on the Moon, serving as a crucial steppingstone for future Mars exploration. Astronauts on these ambitious missions will have to successfully complete complex tasks, which will frequently involve rapid and effective decision making under unfamiliar or high-pressure conditions. Exposure to low doses of space radiation (SR) can impair key executive functions critical to decision making. This study examined the effects of exposure to 10 cGy of Galactic Cosmic Ray simulated radiation (GCRsim) on decision-making performance in male and female rats with a naturally low predisposition for risk-taking (RTP) prior to exposure. …

Department Radiation Oncology & Biophysics Faculty Publications
Future Artemis-class missions to Mars will expose astronauts to prolonged space radiation (SR), sleep disruption, and operational demands requiring greater autonomy, placing decision making and executive function at heightened risk. Both SR and sleep fragmentation (SF) independently impair cognition, yet their combined effects remain poorly understood. Using the Associative Recognition Memory and Interference (ARMIT) task, we assessed cognitive performance in male rats exposed to 10 cGy of Galactic Cosmic Ray simulation (GCRsim), SF, or both. Under well-rested conditions, GCRsim-exposed rats exhibited overt deficits in the C.1.2 stage, performing at chance when reinforcement contingencies shifted, consistent with impaired cognitive flexibility. In …
Cleansing Our Recycling Failures: How Guilt And Outrage Lead To Different Types Of Pro-Environmental Behavior, Cody D. Packard
Cleansing Our Recycling Failures: How Guilt And Outrage Lead To Different Types Of Pro-Environmental Behavior, Cody D. Packard
CGU Theses & Dissertations
Most Americans view recycling as “the right thing to do,” yet U.S. recycling rates lag behind other developed countries, and Americans are quick to justify why they do not recycle more (e.g., laziness, inconvenience). Recent messaging has highlighted recycling failures in the U.S., but how effective are these messages, and do they create individual behavioral changes? According to research on moral self-regulation, failing to act morally can threaten a person’s moral self-concept, eliciting moral emotions (i.e., guilt and outrage), and motivating compensatory behavior (such as increased recycling). Three studies examined whether watching a video about poor recycling in the U.S. …

Introduction: Neonatal hypoxic-ischemic encephalopathy (HIE) is neurological disease caused by the deprivation of oxygen and blood flow to the brain during the developmentally-critical perinatal period. Therapeutic hypothermia (TH) is the standard of care treatment for HIE, though cognitive deficits can persistent throughout life despite treatment. The nature of these deficits, and the impacts of TH and sex are not well understood, and this presents a key barrier in the development of novel therapeutics.
Methods: The goal of this study was to enhance the characterization and measurement of cognitive outcomes with tasks that measure spontaneous behaviors in a rodent models of …

Optimal decision-making requires consideration of internal and external contexts. Biased decision-making is a transdiagnostic symptom of neuropsychiatric disorders. We created a computational model demonstrating how the striosome compartment of the striatum constructs a context-dependent mathematical space for decision-making computations, and how the matrix compartment uses this space to define action value. The model explains multiple experimental results and unifies other theories like reward prediction error, roles of the direct versus indirect pathways, and roles of the striosome versus matrix, under one framework. We also found, through new analyses, that striosome and matrix neurons increase their synchrony during difficult tasks, caused …
