Access Denied: An Argument Against King’S Propositional Access Principle, Jesse Fitts

Philosophy Faculty Research

Accounts of propositions face a problem that originates in the ontology of numbers: If propositions are abstract and causally isolated, then it’s unclear how agents cognitively access them. Jeff King presents a solution to this problem for his theory of propositions. King’s solution follows from a more general principle of cognitive access, which this paper challenges.

The Utilization Of String Pulling To Determine Female Rats' Dual Cognitive Motor Task Performance Following Space Flight Stressor Exposure, Doc-Haden Rodgers, Nicole M. Atttallah, Teresa L. Garcia, Nuhamine A. Moges, N. A. Moges, K. D. Omengan, J. F. Cortez, K. S. Dhede, A. A. Blackwell

Undergraduate Research Symposium Posters

During deep space exploration, astronauts depend on mission-essential performance in Dual Cognitive Motor Tasks (DCMT), such as receiving information from ground control to assemble and configure wires during a spacewalk. DCMT relies upon processing cognitive and motor information simultaneously. Previous research on rodent models has shown various impairments in cognition and motor function in separate tasks after exposure to deep space radiation and sleep fragmentation (SF). However, an assessment of DCMT performance in rodents has not been established. Rats and humans use similar hand-over-hand movements to pull a string, and task demands may be varied to assess cognition and motor …

The Characterization Of Cooperative String-Pullung Behavior In Rats After Exposure To Space Flight Stressors, Teresa L. Garcia, Nuhamine A. Moges, Sierra Ordonez, Nicole M. Attallah, D. H. Rodgers, A. Adhikari, K. D. Omengan, D. Lloyd, S. L. Gleed, A. A. Blackwell

Undergraduate Research Symposium Posters

Astronauts work cooperatively to complete tasks on missions through deep space where they will experience stressors, including radiation and sleep fragmentation, that may impair performance. Animals work together to achieve a common goal during cooperative tasks using string-pulling behaviors. While string-pulling behavior has revealed deficits in rat sensorimotor function after exposure to space flight stressors, it has yet to be determined if rats will engage in cooperative string-pulling or if these stressors will influence cooperation. Thus, to explore how space flight stressors impact cooperative behavior, female Wistar rats were exposed to either sham (n = 8) or 10 centi-grays of …

Measurement And Scale Development Skills For Public Health Doctoral Scholars, Manoj Sharma

UNLV Best Teaching Practices Expo

Web-based synchronous teaching is gaining popularity all over the world. In web-based synchronous teaching, both pedagogical robustness and the building of content expertise are mandatory. I taught a new doctoral course, HED 763 Measurement and Scale Development in Social and Behavioral Health in the Spring of 2022. The specific teaching techniques that I used were (a) enhanced pedagogical features that included delivery as web-based synchronous, organizing the course in Canvas and making it available from day 1, recording all lectures beforehand in Panopto, utilizing case studies, employing WebEx and its breakout sessions feature, guest lectures, and having weekly skill-building activities …

Investigating The Impact Of Dividing Attention On Auditory And Visual Object Memory, Sharica Lee, Alexa Salomon, Laura L.S. Werner, Kevin D. Mohawk, Maggie Mcmullin

Undergraduate Research Symposium Posters

Recently, we found that dividing attention reduced recollection and familiarity for visual objects, but a different pattern emerged for auditory object memory: auditory object recollection was not affected by dividing attention. This could be attributable to differing levels of baseline performance with visual memory far exceeding auditory memory. Thus, we attempted to equate baseline performance in both modalities in order to adequately investigate the previous findings.

Peripheral Storytelling: Cinematic Structures And Audience Agency, Carlos Tkacz

Far West Popular Culture Association Annual Conference

A cultural phenomenon we are all unfortunately familiar with is terrible movies. By terrible movies I mean the kind that lack any semblance of structure, movies in which the characters are flatly drawn, the storylines are predictable, and the writing is especially bad. More specifically, I am interested in why these movies seem to be breeding without end and are no longer relegated to (maybe they never were) the low budget genre films some of us love to hate. I am talking here about the relatively new phenomena of the high-budget, popular-yet-terrible film.

Specifically, I am interested in applying Structuralism, …

Recognition Memory For Auditory And Visual Objects, Sharica Lee, Alexa Salomon, Kevin Mohawk, Laura Werner

Undergraduate Research Symposium Posters

Visual object memory is superior to auditory object memory. Our past research showed that auditory memory was less sensitive to divide attention during study, which may be attributable to representational differences between auditory memory and visual memory.

In the present study, we attempted to equate auditory and visual memory representations in order to adequately investigate the impact of dividing attention on recognition memory.

Recognition memory is thought to rely on two distinct processes, recollection and familiarity. Recollection involves the retrieval of precise qualitative detail and is the most sensitive to dividing attention.

Infants' Intermodal Knowledge Of Gender Using Faces And Voices, Bijoux Cheun, Christina Saliba, Alexis Rice, Marian Espina

Undergraduate Research Symposium Posters

Infants begin to use intermodal knowledge to match male and female faces to the corresponding voice, in their first year of life.

Infants have more experience with female faces which should lead to greater intermodal knowledge of female faces.

Previous studies have found inconsistent results. This could be due to the type of stimuli used.

This study uses several pairs of static and dynamic faces to investigate how methodological differences may impact infants' performance.

Forgetting In Item Recognition And Pattern Separation, Mateo Marquez, Rhiannon Soriano Smith

Undergraduate Research Symposium Posters

Forgetting is commonly defined as the inability to access information that was once successfully encoded and could be retrieved with a cue, but now leads to memory failure (Frankland et al. 2013).

Memory representations based in the hippocampus engage in pattern separation and are more prone to decay than interference (Sadeh & Pertrzov, 2020).

Extra-hippocampal representations are more prone to interference than decay (Hardt et al. 2013).

Pattern Separation refers to keeping memory representations distinct from one another.

Is there more decay in pattern separation and more interference in item recognition?

The Influence Of Unitization On Recognition Memory, Ting Tong, Amaya D. Bolling-Mcdevitt Hernandez, Audrey Kirsch, Alanna N. Osmanski

Undergraduate Research Symposium Posters

Previous research on recognition memory assumes that associative recognition relies on recollection, whereas item recognition relies on a combination of recollection and familiarity. Unitization refers to the encoding strategy where two separate items are perceived as a single coherent entity or object. Research has demonstrated that unitization can facilitate familiarity-based recognition by generating representations of the stimulus and integrating it into a unified whole. To investigate this issue, we examined the effect of unitization on memory for word-pairs through two types of tests:

Associative Recognition: judge whether word pairs occurred together

Item Recognition: judge whether single words are old or …

Peripheral Blood Cell Counts As Potential Biomarkers For Alzheimer's Disease: A Look At Polygenetic Risk Scores, Melika Cummings, Yimei Lu, Joan Manuel Cue, Neel Patel, Jenifer Do

Undergraduate Research Symposium Posters

Blood-based biomarkers for neurodegenerative illnesses such as Alzheimer's disease (AD) have been extensively researched. Alzheimer's disease (AD) is a progressive neurological illness whose progression has been ascribed to gene expression. However, the pathophysiology of these disorders and its relationship to other abnormalities remain unknown. AD has been connected to PBCs, which include erythrocytes, platelets, and leukocytes and have a complicated interaction with the brain system. The pathogenesis of PBCs has been related to a negative influence on established neurodegenerative illnesses such as Alzheimer's. Candidate gene association studies have become more common as progress in mapping the human genome has increased …

Quiroz, Ganesh M. Babulal

Social and Behavioral Health Faculty Research

Sex or gender differences in the risk of Alzheimer’s disease and related dementias (ADRD) differ by world region, suggesting that there are potentially modifiable risk factors for intervention. However, few epidemiological or clinical ADRD studies examine sex differences; even fewer evaluate gender in the context of ADRD risk. The goals of this perspective are to: (1) provide definitions of gender, biologic sex, and sexual orientation, and the limitations of examining these as binary variables; (2) provide an overview of what is known with regard to sex and gender differences in the risk, prevention, and diagnosis of ADRD; and (3) discuss …

Transdisciplinarity In Experience Design: A Global Survey Of Higher Ed Programs In Exd/Xd, Yvonne Houy

Creative Collaborations

In our age of ubiquitous devices and digital media it is the perceived value of the end-to-end experience that brings people to a place. Designing inspiring and emotionally engaging end-to-end experiences requires experts in a wide range of disciplines committed to an interdisciplinary collaboration that can arrive at transdisciplinary design - the sum becomes greater than its parts.

Civil engineering, hospitality, business, psychology, digital User Experience (UX) design, and experience data analysis need to be seamless integrated with the fine and performing arts and design fields:

• Architecture, interior, landscape and sound design actively engage the senses.

• Graphic and fine arts …

Development And Validation Of A Shortened And Practical Frailty Index For People With Intellectual Disabilities, J. D. Schoufour, A. Oppewal, M. C. Van Maurik, Thessa Hilgenkamp, R. G. Elbers, D. A.M. Maes-Festen

Physical Therapy Faculty Research

Background: There is no widely used instrument to detect frailty in people with intellectual disabilities (IDs). We aimed to develop and validate a shorter and more practical version of a published frailty index for people with IDs. Method: This study was part of the longitudinal ‘Healthy Ageing and Intellectual Disability’ study. We included 982 people with IDs aged 50 years and over. The previously developed and validated ID-Frailty Index consisting of 51 deficits was used as the basis for the shortened version, the ID-FI Short Form. Content of the ID-FI Short Form was based on statistics and clinical and practical …
