Feedback Timing: Relationship To Student Success In Online Education, Emaleia J. Anton, Nicholas A. Smith

Student Research Symposium

It’s important that researchers identify factors that support student success in online education because utilization of remote learning has increased over the years. Feedback timing is a vital factor contributing to student success in online educational environments. The purpose of this research is to experimentally examine effects of feedback timing on online student success, which this study operationalizes as student perception of self-efficacy. Conducting a between-subjects experimental design, 100 undergraduate students will participate in an online synchronous crash course and will be randomly assigned to different conditions of the independent variable where they will receive either prompt or delayed feedback …

Exploring A Possible New Mechanism Of The Predictive Coding Theory Of Consciousness With A Binocular Rivalry Experiment, Sai Kiersarsky, Madison Cho-Richmond

Student Research Symposium

Predictive Coding is a theory of brain function in which consciousness is a predictive model generated by higher brain regions that constantly updates its predictions about the cause of upwards flowing data – often sensory perception data. Binocular Rivalry is a phenomenon where, when each eye is presented with a completely different image, consciousness alternates between the images rather than attempting to fuse both images into one.

Here we present the same image to both eyes, but with each image partially blurred in differing areas to test if consciousness weaves together the clear areas to synthesize a single crisp image. …

Clinical Swallowing Evaluations Via Telehealth: A Scoping Review & Ideas For Implementation, Stephanie J. Merrill

Student Research Symposium

Previous research has been conducted on telehealth clinical swallowing evaluations in a number of populations (Burns et al., 2017; Morell et al., 2017; Sharma et al., 2011; Ward et al., 2012), however, to our knowledge, no research has examined this topic for people with Amyotrophic Lateral Sclerosis (pALS). Given the impact of the novel coronavirus disease 2019, the need for virtual access to healthcare, particularly for people with chronic medical conditions, has become paramount. The goal of this project is to review the literature examining techniques used for virtual clinical assessment of swallowing and to outline approaches that could be …

Stuttering Accommodations In Professional Environments: The Intersectionality Between Multiculturalism, Multilingualism, Stigma, Disability Identity And Rights, Sulema Rodriguez, Megann Mcgill

Student Research Symposium

Stuttering is a fluency disorder that disrupts the forward flow of speech (Guitar, 2014). People who stutter (PWS) have been falsely represented in the media and negatively perceived by the general public (Boyle, 2011; Williams, 2015). This public stigma, including cultural and linguistic differences, contributes to the development of self-stigma (Dean & Medina, 2020; Gerlach et al., 2018; Plexico et al., 2019). Stuttering public stigma also leads to decreased earnings and opportunities in the workplace and higher education discrimination (Gerlach et al., 2018; Klein & Hood, 2014). Consequently, there has yet to exist a research study that considers the intersectionality …

The Role Of The School Slp In Treatment Of Tbi: Implications For Bipoc Students, Simone Speer, Susan Wiggins

Student Research Symposium

Historically, BIPOC (Black, Indigenous, People of Color) students are disciplined more frequently, and more severely than their white counterparts in educational settings. This often includes suspension, expulsion, arrest, entry into the juvenile justice system, and incarceration. Within this group of students, there is a disproportionately large number of students experiencing executive functioning and communication deficits as a result of TBI. Research tells us that these impairments often present as a wide variety of behaviors which in BIPOC students are often misdiagnosed by school administration as defiant or disruptive and are disciplined more heavily than their white peers. Speech language pathologists …

A Feature Matching Protocol For Telepractice Augmentative And Alternative Communication (Aac) Evaluation, Jessi Ryann Gallagher

Student Research Symposium

Speech-Language Pathologists (SLPs) support individuals with communication disabilities who experience barriers to meeting all of their communication needs through spoken language. SLPs assess clients who may benefit from augmentative and alternative communication (AAC) which includes tools and strategies to support communication.

There are many barriers to effective AAC service delivery. Clinicians often receive limited training in AAC assessment or treatment, and external evidence regarding AAC assessment techniques and strategies is needed. Further, increased health risks associated with face-to-face interactions due to the COVID-19 pandemic forced many clinicians to transfer services to telepractice. This likely resulted in additional barriers to effective …

Links Between Sound-Category Learning & Memory Skills In Neurotypical & Language-Learning-Disabled Adults, Katharine Ross, Mario Rene Jimenez-Cruz

Student Research Symposium

This study will examine how memory systems are intertwined with language learning by assessing participants’ different memory systems and relating memory skills to the ability to learn and categorize unfamiliar sounds.

Based upon similar work (Maddox, Ing, & Lauritzen, 2006), we hypothesize that the data will show a link between procedural memory and implicit sound categorization, and between declarative memory and explicit sound categorization. Additionally, based on the predictions of the Procedural Deficit Hypothesis (Lum, Conti-Ramsden, Page, & Ullman, 2012), we believe adults with LI will (1) show a weak connection between procedural memory and implicit sound categorization accuracy; (2) …

Portland Urban Coyote Project: A Review Of Citizen Science's Utility For Researching Urban Canids And The Human Environment, Keith David Vanderbrooke

Dissertations and Theses

The Portland Urban Coyote Project (PUCP) is a citizen science project that allows community members to upload coyote (Canis latrans) sighting data to a database that is used to create a public web map; contributors often add observations as well. I analyzed one year of PUCP comment data in order to assess the utility of the citizen science methods used by PUCP for urban carnivore research. I code and summarize findings from PUCP's data, compare the extracted data to other research studies of urban coyote from other regions, and find that results from this analysis supports conclusions made …

Exploring The Correlational Relationship Of Interpersonal Discrimination And Leader-Member Exchange, Bryan Wesley T. Hamilton

Student Research Symposium

Stigmatized individuals use several compensatory strategies to offset the negative impact of interpersonal discrimination in the job application process, including increased positivity, providing individuating information, or identity disclosures. Using interviews and surveys, we aim to expand this literature by examining how these processes unfold after stigmatized individuals have gained employment and are interacting with coworkers. These compensatory strategies can have varying impacts on targets’ workplace relationships, job satisfaction, overall performance, and psychological and physical health outcomes. Leaders and other powerful organizational members can mitigate these negative outcomes and improve employee well being through leader member exchange and perceived supervisor support. …

Teaching Children Emotional Intelligence: A Closer Look At The Barbie Vlogs, Jillian C. Britton

Student Research Symposium

In 2015, toy company Mattel began a YouTube vlog starring a 3D animated Barbie that featured many vlogs seemingly geared at increasing children’s emotional intelligence. One concern about this promising resource is that previous research suggests that cultural relevance has a notable role in the receptivity of children's media content, and Barbie may not be the most versatile role model for children of all demographics. Using a quasi-experimental matched-groups design, this proposed research aims to evaluate the impacts of the Barbie vlogs on children’s levels of emotional intelligence, and determine whether the children's ethnicity (Black or White, within the scope …

Does Reading Violent Books Increase Aggression? Perceptions Of An Overlooked Medium, Cassandra H. Muniz

Student Research Symposium

In the ongoing media violence debate, video games, movies, and television are regular targets of scrutiny. Yet, largely absent from the discussion is a popular, age-old medium: the book. Do people think that reading violent subject matter can increase aggression? How do first- and third-person perceptions differ? Using an online survey, the author collected quantitative data on adults’ (N = 160) perceptions of how much violent books affect aggression in themselves, the average adult, and the average child. The author hypothesized that participants would perceive the medium to have stronger effects on other adults' aggression than on their own. …

L2 Prosodic Variation: The Effect Of L1 Typology On L2 Question Intonation, Phoebe Cordova

Student Research Symposium

There has been a growing body research work conducted on L2 prosodic acquisition and cross-linguistic prosodic transfer, with studies more recently turning to the examination of suprasegmental prosodic phenomena like intonation. These studies analyzed data from a variety of L1s and have primarily focused on the impact of age of acquisition and proficiency level on the production of L2 intonation. Further, these studies have almost entirely used elicited data as the basis of their investigation. Several models have been put forth to account for L2 speech production, with the L2 Intonation Learning theory (LILt) (Mennen, 2015) being the most recently …

Boredom And Risk-Taking In Mania, Rose M. Jardine, Nicholas A. Smith

Student Research Symposium

The purpose of this proposal is to examine perceived boredom and risk-taking exhibited during manic episodes in atypical bipolar 1 disorder. I propose to recruit at least 100 participants, ages 18-25, from Intensive Outpatient Programs, Community Programs, and Inpatient Programs who will be verified to be in a manic episode and asymptomatic for psychosis by the on-site providers. A pilot study of two videos will be performed. Participants will be randomly assigned to view one of two videos: “calm” or “exciting”. They will respond to the Boredom Proneness Scale questionnaire at both pre- and post-test as well as the revised …

The Impact Of Professors’ Heterosexual Identity In Higher Education Classrooms, Sam Barr

Student Research Symposium

This proposed study is concerned with lesbian, gay, and bisexual (LGB) student’s perceptions of classroom climate, and the potential negative impacts of these perceptions. A poor classroom climate can decrease student participation and contribute to minority stress, which can be a barrier to successful higher education. In this study, we plan to inspect the impact of professors’ heterosexual identities on their scores of Classroom Diversity Climate (CDC). We hope to recruit heterosexual Portland State University professors and their students for our study. After randomly assigning professors to either an intervention on integrative heterosexuality or to a waitlist (control) group, we …

A Comparison Of Formulaic Language In Student, Researcher, And Practitioner Reports In Civil Engineering, Amy Akenson

Student Research Symposium

Most Civil Engineering (CE) students want to work in the industry when they graduate, but often only have experience with academic writing contexts. The Civil Engineering Writing Project (CEWP) was created to assist CE professors in preparing students for professional writing. Using computer-assisted analysis techniques, I examined papers collected through the CEWP to analyze how formulaic language was being used by students and current practitioners, as well as academic researchers. Specifically, I looked for n-grams, which are same-length phrases found at a higher frequency in the text than other phrases, for example, “as a function of” or “in order to …

The Influence Of Surrealist Art On Popular Ads, Sydney G. Thomas Ms.

Student Research Symposium

All ads draw influence from something, most of the time it is from an art movement that will mirror the mental state of the current population. The art influence used for today’s media is surrealist art, due to its chaotic representation of life that mirrors the tumultuous events gen Z and millennials have grown up with. In the surrealist art movement, the general population experienced great anxiety and grappled with the idea of the inner, subconscious self and the represented conscious self. Today, the issue of social media, what is presented compared to what is real, creates an atmosphere where …

Implicit Learning In Preschoolers With And Without Developmental Language Disorder, Abigail Tolomei, Josie Johnson, Katharine Ross, Genesis Ocegueda Enciso, Carolyn Quam, Aminah Kariye, Molly Franz, Rachel Atkinson

Student Research Symposium

The purpose of this study was to compare implicit learning of sound categories across preschoolers with and without developmental language disorder (DLD), in order to test the Procedural Deficit Hypothesis (Lum, Conti-Ramsden, Page, & Ullman, 2012), which argues that procedural memory, the basis for implicit learning, is the core deficit in DLD. We tested 52 preschoolers in total, 26 with typical language development (TLD), and 26 with DLD. Preschoolers participated in a computer-based task assessing implicit mapping of sounds to meanings. We predicted that children with DLD would show deficits in implicit learning relative to children with TLD. Results were …

Oregon's Racial Purity Regime: The Influence Of International Scientific Racism On Law Enforcement, Legislation, Public Health, And Incarceration In Portland, Oregon During The Victorian And Progressive Eras (1851-1917), Katherine N. Bush

Dissertations and Theses

In 1983, the Oregon State legislature repealed the eugenic sterilization law that had been in use for 60 years. Initially passed during the Progressive era, this law epitomized the State's legacy of surveilling, policing, caging, and inflicting brutality on marginalized and racialized communities who were deemed dangerous, threatening, or contagious. Public health leaders, political officials, law enforcement authorities, and private charities worked together as a multivalent system to maintain racial purity in the State. This racial purity regime drew upon a legacy of international pseudo-scientific racism to justify and bolster policies, legislation, and practices that targeted impoverished communities, people of …

Using Information Theory To Extract Patterns From Categorical Raster Data, David Percy

Complex Systems Faculty Publications and Presentations

Information theory -- Reconstructability Analysis (RA) implemented in the Occam software -- was used to extract patterns from National Land Cover Data. The aim was to predict temporal change in evergreen forests from time-lagged and spatially adjacent states. The NLCD satellite data were preprocessed with Python and submitted to Occam for analysis, and Occam output was also explored with R-studio. The effectiveness of RA methodology for the analysis of this type of categorical space-time grid data was demonstrated.

Sources Of Individual Differences In Adults’ Ict Skills: A Large-Scale Empirical Test Of A New Guiding Framework, Alexandra Wicht, Stephen Reder, Clemens M. Lechner

Applied Linguistics Faculty Publications and Presentations

We develop an integrative conceptual framework that seeks to explain individual differences in the ability to use information and communication technologies (ICT skills). Building on practice engagement theory, this framework views the continued usage of digital technologies at work and in everyday life (ICT use) as the key prerequisite for the acquisition of ICT skills. At the same time, the framework highlights that ICT use is itself contingent upon individual and contextual preconditions. We apply this framework to data from two recent German large-scale studies (N = 2,495 and N = 2,786, respectively) that offer objective measures of adults’ ICT …

Psychometric Properties Of The Brief Version Of The Questionnaire Of Olfactory Disorders In Patients With Chronic Rhinosinusitis., Jose L. Mattos, Todd Bodner, Jess C. Mace, Rodney J. Schlosser, Daniel M. Beswick, Vijay R. Ramakrishnan, Jeremiah A. Alt, Spencer C. Payne, Timothy L. Smith, Zachary M. Soler

Psychology Faculty Publications and Presentations

The Questionnaire of Olfactory Disorders-Negative Statements (QOD-NS) is a 17-item instrument measuring olfactory-specific quality of life (QOL). However, in clinical research patients can be overwhelmed with multiple questionnaires. We recently developed the 7-item brief QOD-NS (B-QOD). Our objective was to evaluate the psychometric properties of the B-QOD in both the development (D) sample, and in a separate replication (R) sample.

The Revival Of Termination: Fragmenting John Collier’S Bureau Of Indian Affairs, Jacob Taylor

Phi Alpha Theta Pacific Northwest Regional Conference

Abstract: The Indian New Deal has been studied through two opposing lenses. Some historians attempt to paint John Collier, Bureau Commissioner under President Roosevelt, as a visionary who attempted to save Native American sovereignty while others denounce his legislation and time in office as ill-fated and corrupt. These two opposing views fail to illustrate the broader context of Collier’s BIA and do not provide an explanation for the ultimate failure of the Indian New Deal. Furthermore, they offer a largely monocausal explanation for the failure of the Indian New Deal. I argue that the BIA had been faltering for a …

The La Uprising On Camera: The Changing Mediascape And Its Influence On Conceptions Of Race And Poverty, Neave Carroll

Phi Alpha Theta Pacific Northwest Regional Conference

Using the LA Riots as a case study, this paper examines the impact broadcast journalism had on electoral politics in America by deconstructing the media discourse surrounding the event and reviewing the electorate’s response. Mainstream network broadcast transcriptions and archival footage represent the bulk of source material used. These sources suggest changes in journalistic methods, such as the adoption of the 24-hour news cycle and sensationalist reporting, as well as new technologies like the camcorder which led to the advent of eyewitness reporting, coalesced to influence politics in 1992. Urban crime was linked to an ailing economy, encouraging politicians to …

Pacification Gone Awry: The U.S Failure To Underpin Hearts And Minds In South Vietnam, 1966–1968, Simon Mai

Phi Alpha Theta Pacific Northwest Regional Conference

Abstract: Throughout the escalation of American involvement in Vietnam from 1964 – 1968, one key strategy focused on pacification – the winning of the allegiance of South Vietnamese civilians to the Saigon-based Government of Vietnam (GVN). This paper will argue that American/GVN implementation of pacification programs at the provincial and village level revealed three fundamental factors that proved fatal and counterproductive. These factors were the political and social entrenchment of the Viet Cong or National Liberation Front (NLF), the provincial cronyism and corruption of GVN, and the indiscriminate application of American firepower in support of General William Westmoreland’s strategy of …

Days Of Decision: San Francisco’S 1960 House Un-American Activities Committee Protest As A Turning Point Of The New Left, Sophie Carter

Phi Alpha Theta Pacific Northwest Regional Conference

After the degradation of union power throughout the McCarthy era, a new politics took hold among young Americans, and its academic roots and appeal to young leftists established the university as the new institutional mediator for left-wing radicalism in the 1960s, allowing college students to promote antiwar, civil rights, and civil liberties campaigns both on and off campus. Years before the major events that are tied to the New Left in American collective memory, however, Bay Area college students’ protests against the House Un-American Activities Commission garnered national media attention for their perceived radicalism in the face of the federal …

Familiar Ecology: The Demonization Of Spirit Knowledge In Early Modern England And Its Ecological Ramifications, Ryan P. Mealiffe

Phi Alpha Theta Pacific Northwest Regional Conference

Abstract: During the English witch trials of the mid-sixteenth century to 1735, more was on trial than just the accused humans before the bar. Witch trials also threatened an entire mental landscape, the beings that inhabited it, and their relationships with both the accused and the general populace. This ecological ontology coalesced in the other party on trial: the intersectional helpers known as familiar spirits. Spirits animated the natural world, intermingled with flora and fauna, and impacted many aspects of everyday life, representing a keystone species in popular conceptions of nature in early modern England. The assumption of malevolence present …

Born And Bred In Blood: The Fall Of The Aztec Empire, Melina Arciniega

Phi Alpha Theta Pacific Northwest Regional Conference

The fall of the Aztec Empire in 1521 was a surprising feat given the well-known, vast power, and fighting capabilities of the Aztec people. Many questions since then have arisen as to how such a mighty empire had so rapidly fallen. These theories hold implications that the Aztecs were victims to the incoming disease, famine, and domination inflicted by the Spanish conquistador, Hernan Cortes. Alongside these proposals I suggest that by examining archaeological and historical evidence, the Aztec traditional practices were also responsible for its society’s collapse. By identifying the significance of the human sacrifices, the cultural, political, and economical …

Plague And Progress: An Analysis Of Giovanni Boccaccio’S Decameron And Reform During The Initial Outbreak Of The Black Death, Ben Hecko

Phi Alpha Theta Pacific Northwest Regional Conference

Giovanni Boccaccio’s Decameron is a collection of one hundred stories told by a group of people during the initial outbreak of the Black Death in Italy in 1348. Though the work has been interpreted as an escapist piece, this limits its overall value. Through the inclusion of the frame that surrounds the fictional tales, Boccaccio establishes the importance of the plague to the meaning of the work as a whole. Many of the stories that Boccaccio tells attack the immorality of those in positions of authority. These critiques provide a social commentary that addresses the failures of his society and …

The Significance Of Oomoto: Why Imperialization Of Japan Led To An Alternative Religion, Chancellor T. Jenniges

Phi Alpha Theta Pacific Northwest Regional Conference

Abstract: In 1852 Admiral Matthew Perry led an American fleet to Japan and persuaded the Japanese to modernize. Fearful of being colonized by the West, like the Chinese, the Japanese moved to westernize their own economy and society. As a result, they outlawed many historic customs. Japan began to westernize their customs and define religion. Three categories were established, religion, non-religion, and superstition. Any ideology or practice that no longer benefited their goals of westernization was deemed superstitious and removed from the narrative. However, these developments met opposition. One such opponent, Ueda Kisaburō, created an alternative religion called Oomoto in …
