An Erp Measure Of Non-Conscious Memory Reveals Dissociable Implicit Processes In Human Recognition Using An Open-Source Automated Analytic Pipeline, Richard J. Addante, Javier Lopez-Calderon, Nathaniel Allen, Carter Luck, Alana Muller, Lindsey Sirianni, Cory S. Inman, Daniel L. Drane

Psychology Faculty Publications

Non-conscious processing of human memory has traditionally been difficult to objectively measure and thus understand. A prior study on a group of hippocampal amnesia (N = 3) patients and healthy controls (N = 6) used a novel procedure for capturing neural correlates of implicit memory using event-related potentials (ERPs): old and new items were equated for varying levels of memory awareness, with ERP differences observed from 400 to 800 ms in bilateral parietal regions that were hippocampal-dependent. The current investigation sought to address the limitations of that study by increasing the sample of healthy subjects (N = 54), applying new …

The Influence Of Community Trauma And The Behaviors Of Gang Members, Leshelle Franklin

Theses, Dissertations and Culminating Projects

Although there is an abundance of research done on gang members, gang activity, and gang activity in low-income neighborhoods, there is not much research that focuses on the community trauma in low-income neighborhoods; and any relations it may have on or to gang members. Research pertaining to gang members usually focuses on how gang activity affects the lives of non-gang members living in the community. This research study aims to explore community trauma and the behaviors of gang members, from a gang member’s perspective. This research study gives insight into the minds of 10 male African American gang members, as …

Exploring The Intersectionality Between Homelessness And Addiction: A Review, Antonia Miranda

Honors Projects

The homelessness crisis and drug epidemic have been, and continue to, ravage the nation in a manner that is both detrimental to society and humanity. The correlation between substance abuse and homelessness is enormous, though not necessarily causal. The conditions of being homeless coupled with the prevalence of mental illness drastically increases the susceptibility to substance abuse and addiction. On the other hand, addiction and substance abuse can contribute to someone entering homelessness. The intersectionality between the two is frequently ignored, yet critical to address. Informed by research regarding both conditions, the implications for public policy and reform are huge. …

Page And Screen: Storybook Features That Promote Parent-Child Talk During Shared Reading, Gabrielle Strouse, Georgene Troseth, Zachary D. Stuckelman

School of Education Faculty Publications

The purpose of this study was to systematically vary the medium used for shared reading (digital versus print), the presence of an audio narration feature, and the inclusion of a character offering conversational prompts to identify their impact on parent-child language. In a randomized experimental design, 67 children (2.75-5.10 years old) shared a book with a parent twice. Built-in conversational prompts were effective in increasing the quantity and quality of extratextual language and conversation. There was no evidence that the book being digital in format nor having automatically-playing narration decreased language or conversation quality compared to reading the print version. …

The Effect Of Uncertainty On Explanatory Preference, Eli Schwartz-Yermack

Psychological Science Undergraduate Honors Theses

Previous research on political extremism has led to two competing perspectives. One views extremists as being more knowledgeable and informed about politics than moderates, while the other claims it is moderates who know more. These two views appear to have arisen from studies that examined different types of political knowledge. This phenomenon could be explained by extremists and moderates having different preferences when it comes to their consumption of political information. We hypothesized that participants indirectly manipulated to feel more extreme conviction in their political views by manipulating them to feel uncertain would prefer more simple explanations of political issues …

Updating Of Protagonist Information In Narratives, Luke Mcclanahan

Psychological Science Undergraduate Honors Theses

The purpose of the present research was to further examine contested findings in the research literature surrounding the processes readers use to maintain and update their mental representation of contextual information in a text. Research indicates that whether information is directly relevant to the goal of a story’s protagonist influences whether it will be used as a basis for later validation (Levine & Kim, 2019; Levine & Klin, 2001; Lutz & Radvansky, 1997). Some prior research that indicates that participants fail to validate inconsistent contextual information (Albrecht & Myers, 1995; Smith et al., 2020; Smith & O’Brien, 2012) relies on …

Adolescent Perception Of Different Conspiracy-Like Scenarios, Christine Honn

Psychological Science Undergraduate Honors Theses

Conspiracy theories are claims that are unverified, less plausible than the mainstream explanation, and contain a malevolent actor. A potentially related concept is intellectual humility, which is a person's willingness to admit when they are not knowledgeable about a subject and turn to an expert or authority figure for an answer. I hypothesized that adolescents who are more prone to endorse conspiracy theories in general as well as believe in specific conspiracy theories would have lower levels of intellectual humility than their conspiracy-resistant peers. Participants read eight conspiratorial vignettes and answered questions about traits of the vignettes, then filled out …

Effects Of Individual Differences On Influence Of Expert Testimony, Peyton Mosman

Psychological Science Undergraduate Honors Theses

A significant percentage of wrongful convictions are a result of faulty eyewitness identifications. It is understood that jurors are quick to trust and eyewitness testimony, that eyewitness testimonies are reliable only in specific circumstances, and that jurors are rarely privy to importance of the factors that impact the reliability of eyewitness testimony. Although an expert testimony is sometimes a beneficial way to help compensate for this lack of knowledge in jurors, it can sometimes be counterintuitive and cause jurors to disregard all eyewitness testimonies rather than only disregarding the unreliable ones. This study considers four individual difference factors and looks …

External Support: The Importance Of Community Support In Disability Healthcare, Kian Mccabe

Undergraduate Theses and Capstone Projects

Inequalities in healthcare is a common discussion topic every day in the United States and although most Americans are not able to get adequate healthcare, they need one subtopic that I believe is not discussed enough about disability healthcare. More specifically the importance of community support and resources in disability health care. My internship this semester was helping lower-income families find the resources they need for their children with autism spectrum disorder. In this position, I learned that many of the positive activities and resources that would be helpful for their children most families are unable to get because they …

Low-Income Caregivers With Young Children Experience Risk And Resilience Through Pandemic-Related Stressors, Nicole Kingdon, Molly Dubuc, Rosemarie Dibiase

Undergraduate Theses and Capstone Projects

In March 2020, United States government implemented health and safety mandates, including school closures, to prevent the spread of the coronavirus disease (COVID-19). As a result, some caregivers with young children were forced to take on new roles. Low-income households with young children appeared to be more highly impacted than other groups, experiencing acute pandemic-related stressors on top of previous vulnerabilities. Using qualitative analysis, this study examined how low-income caregivers with young children adapted to pandemic-related stressors and how stressors may have altered relationships and well-being in the household (Daks et al., 2020). Two research questions were examined: (1) how …

Trace Dna Detection Using Diamond Dye: A Recovery Technique To Yield More Dna, Leah Davis

Master's Theses

This study aspires to find a new screening approach to trace DNA recovery techniques to yield a higher quantity of trace DNA from larger items of evidence. It takes the path of visualizing trace DNA on items of evidence with potential DNA so analysts can swab a more localized area rather than attempting to recover trace DNA through the general swabbing technique currently used for trace DNA recovery. The first and second parts consisted of observing trace DNA interaction with Diamond Dye on porous and non-porous surfaces.

The third part involved applying the Diamond Dye solution by spraying it onto …

A Survey Of Knowledge And Beliefs On Child Maltreatment, Brooke R. Stettler

Theses, Dissertations and Culminating Projects

Child sexual abuse (CSA) remains a wide-spread problem and challenging to prosecute in a court of law for many reasons, among these being the manner in which children disclose abuse. A recent Supreme Court ruling decided upon the admissibility of expert testimony in cases of CSA, which raise important questions about how lay individuals think about different disclosure behaviors. As such, the current study investigated knowledge and beliefs about two common CSA disclosure behaviors—delayed disclosure and recantation—in a sample of jury eligible lay persons. The primary aims associated with this study were to characterize individuals’ knowledge and beliefs regarding the …

Conversational Dynamics Between Caregivers And Children : The Role Of Elaboration And Autonomy Support On Children’S Memory Reports, Whitney L. Dartnell

Theses, Dissertations and Culminating Projects

Maltreatment allegations most often arise during informal conversations between a child and a non-maltreating parent or caregiver. Due to the sensitive nature of these conversations, the ways in which parents respond and in turn question their children about the events they have experienced can take many forms. The conversational dynamics that occur between caregivers and their children during the subsequent dialogue that ensues can impact the accuracy and completeness of children’s reports, as well as children’s memory of the alleged maltreatment or abuse. Legal professionals and developmental psychologists have expressed concern regarding how such conversations may impact children’s later testimony. …

An Analysis Of The Sophistication–Maturity Of Justice And Non-Justice Involved Youth And Young Adults, Lauren Grove

Theses, Dissertations and Culminating Projects

Juvenile transfer refers to a set of mechanisms whereby a juvenile’s case may be processed in criminal court. Forensic mental health evaluators often assess youths’ risk/dangerousness, sophistication–maturity, and treatment amenability to assist judicial determinations regarding youth disposition. Of these three factors, sophistication–maturity—in which the law is concerned with the extent to which a juvenile defendant’s criminal sophistication and maturity level parallels that of an adult—has traditionally been the most challenging for practitioners to define and apply in practice. The Risk-Sophistication-Treatment Inventory (RSTI) is the only commercially available, specialized forensic assessment instrument for the assessment of youths’ sophistication–maturity. However, this tool …

The Role Of Presentation Media And Perspective On Direction Giving, Rebeca Costa Do Nascimento

Theses, Dissertations and Culminating Projects

Research on spatial cognition has tried to understand how perspective (route vs. survey) and media (visual vs. verbal) influence people's spatial cognition on different tasks (e.g., map drawing, navigation, semantic and distance estimation) when materials are presented simultaneously. However, less research has focused on how those spatial features influence people's direction giving when materials are presented sequentially, one piece at a time. In the present study, participants were presented with fragments of sentences and map segments. After learning the materials, they were asked to give directions using their own words or including cardinal terms. As hypothesized, participants provided more accurate …

Adult Age, Moral Foundations, And Moral Stereotyping, Peter Khalatian

Theses, Dissertations and Culminating Projects

The main aim of the current thesis was to investigate the role of adult age in the moral stereotyping of moral foundations. The five core moral foundations of Moral Foundations Theory were measured through an online self-report survey, including the individualizing foundations of harm and fairness and the binding foundations of in-group loyalty, authority, and purity. Participants (n = 597; age range 19 to 85) were randomly assigned to one of three experimental conditions: the self-evaluation condition where participants completed the moral questionnaire as themselves, a condition where participants provided ratings as they believed a typical younger adult would answer …

Investigating Spinal Cord Injury At Different Locations On The Spinal Cord Using Diffusion Tensor Imaging, Haley Nauman

Theses, Dissertations and Culminating Projects

The current study is derived from a larger study by Yao et al. (2019) that attempts to understand if Diffusion Tensor Imaging (DTI) is a good diagnostic tool for distinguishing spinal cord injured (SCI) participants from healthy controls from a structural perspective. Additionally, the study aims to determine whether the DTI parameters and the clinical functional scores of the Spinal Cord Independence Measure (SCIM) improve over time for SCI when rehabilitation is implemented. The current study has the same aims but takes Yao’s work further by dividing cervical SCI participants based on the exact location of injury (i.e., upper and …

The Effects Of Traumatic Brain Injury On Empathy And Quality Of Life, Nicholas James Pek

Theses, Dissertations and Culminating Projects

Physical, emotional, cognitive, and social problems can all result from a traumatic brain injury. The focus of this present research was to investigate individuals with moderate-to-severe TBI who lack empathy and how that lack in empathy might impact their quality-of-life. Individuals with moderate-to-severe TBI between ages 18 and 65 (N=39) completed questionnaires including the Quality of Life after Brain Injury (QOLIBRI) and Empathy Quotient (EQ) as part of a larger study. A correlational analysis was completed between the total scores on the EQ and total scores on the QOLIBRI before splitting the participants into groups. A relationship between total scores …

Barriers To Treatment For Socially Anxious Black American Students In Urban Public Schools, Grace Martin

Theses, Dissertations and Culminating Projects

Social anxiety is frequent and debilitating for Black adolescents with associated impairment (La Greca & Stone, 1993; Stein & Kean, 2000; Van Ameringen et al., 2003). Despite its prevalence and severity, Black adolescents are less likely to seek mental health treatment due to systemic and social barriers such as accessibility and social stigma (Bains, 2014; Lindsey et al., 2006; Lindsey et al., 2013). Barriers to seeking treatment, particularly for socially anxious Black adolescents, are mostly absent in the literature and thus require investigation. To understand culturally specific factors related to social anxiety symptoms as well as to investigate perceived barriers …

The Role Of Attentional Control And Social Influence In Risky Decision Making, Samantha Salernitano

Theses, Dissertations and Culminating Projects

People often are required to make decisions in a collaborative environment, including decisions that deal with risky or uncertain outcomes. The present thesis investigated the role of both social influence and individual cognitive factors (attentional control) in risky decision making. Two measures of attentional control (a Stroop task and a Go/No-go task) were completed by participants. Risky choice was then measured through a hypothetical monetary gambling task where participants made choices between a smaller-guaranteed reward or a larger-risky reward. Three blocks of the risky-choice task were completed. Participants in the individual condition completed all three blocks of trials individually. For …

How Race And Gender Moderate The Effect Of Facial Trait Inferences On Leadership Perception, Calista Wong

Theses, Dissertations and Culminating Projects

Research on first impressions suggests that facial trait inferences guide judgments in many domains, including perceptions of leadership ability. This study explored the extent to which race and gender moderate such inferences on the perception of leadership. A total of 179 participants rated facial stimuli on one of three traits: leadership ability, dominance, and warmth It was hypothesized that perceived warmth would benefit Black male targets more than White and Asian male targets, and perceived dominance would benefit male White and Asian male targets more than Black male targets. No strong hypotheses were specified for female targets, as research on …

The Language Of Mechanical Support In Children: Is It ‘Sticking’, ‘Hanging’, Or Simply ‘On’?, Julia Marie Hauss

Theses, Dissertations and Culminating Projects

Research has found that children begin to differentiate in the terms they use to encode support. In English, BE on, the Basic Locative Construction (Levinson & Wilkins, 2006; “put on” in dynamic events) tends to encode support-from-below (e.g., cup on table), whereas lexical support verbs (e.g., hang, stick, tape, glue, etc.) tend to encode mechanical support. We see this differentiation in semantic space by six years of age (Johannes et al., 2016). Although this differentiation occurs, we can still use BE on to encode all types of support, just as we can use a variety of lexical verbs (e.g., the …

The Effects Of Ketamine On Performance In The Progressive Ratio Task And Nucleus Accumbens 5-Ht1b Receptor Expression In Wistar-Kyoto Rats, Andriy Fomin

Theses, Dissertations and Culminating Projects

In the present study, we integrated the recent findings about rapid antidepressant action of ketamine and possible involvement of the serotonergic system, and 5-HT_1B receptor in particular, in the pharmacodynamics of this drug. We modeled anhedonia, a prominent symptom of depression, using the progressive ratio test in Wistar Kyoto rats. This strain of rat is reportedly an endogenously stress-reactive organism that displays an anhedonia-like endophenotype. We hypothesized that Wistar-Kyoto rats’ performance would be impaired, compared to Wistar-Han controls, on this reward- and motivation- related task and that the treatment with 1o mg/kg ketamine 24 hours prior to testing will …

Exoskeleton Gait Training To Improve Walking Adaptability In Persons With Multiple Sclerosis, Alfonse Gaite

Theses, Dissertations and Culminating Projects

There have been numerous research studies investigating the feasibility and effectiveness of exoskeleton-assisted gait training as a treatment for lower extremity motor rehabilitation in persons with multiple sclerosis (MS). However, while most of the research on exoskeleton- assisted gait training investigate its impact on general gait and balance during ambulation, investigating the effectiveness of exoskeleton gait training in improving walking adaptability remains underexplored. The present study aims to investigate the effectiveness of exoskeleton- assisted gait training compared to traditional gait training on improving walking adaptability in persons with MS. The study is a secondary analysis using data from a Kessler …

From Judgment To Action : Moral Cognition And The Tenuous Link To Moral Courage, Nathan Kemper

Legacy Theses & Dissertations (2009 - 2024)

Though specifics differ across cultures and even across individuals, research has shown surprising consensus as to what constitutes immoral behavior across societies (e.g., murder, theft). Even though much research has broadened our understanding of moral cognition, comparatively few studies have investigated moral action. There are real-world examples of people trying to intervene against immoral behavior, a behavior known as moral courage. This dissertation, comprised of a total of six studies across three manuscripts, seeks to add to the corpus of moral psychology by bridging the gap in knowledge regarding how connected moral cognition and action are. In the two studies …

Age-Of-Acquisition (Aoa) Impacts Spelling Error Detection : Evidence From An Online Proofreading Task, Madison Laks

Legacy Theses & Dissertations (2009 - 2024)

During reading, words are processed faster if they are rated as being acquired early in life compared to later in life (i.e., age of acquisition effects; AoA). Given that the task demands for proofreading differ from reading, we investigated if AoA effects extend to an online proofreading task. Specifically, early- and late-acquired target words were embedded in sentence frames after being matched for a variety of potentially confounding variables, including word frequency, length, imageability, OLD-20, and familiarity (using the stimulus set from Juhasz & Sheridan, 2020). The participants rapidly proofread these sentences for spelling errors, and our results showed that …

Resilience In Girlhood: An Analysis Of The Social Determinants Of Anxiety Disorders For Adolescent Girls, Maggie Sullivan '23

Honor Scholar Theses

Anxiety disorders affect twice as many women as men and often begin in adolescence or young adulthood, which is a unique period of accelerated development and identity formation. Evidence points to social determinants of health (SDH) such as adverse childhood experiences (ACEs), socioeconomic status (SES), education, social media, and resilience that lead to this discrepancy. Girlhood is a distinct adolescence because girls face the effects of more ACEs, self-objectification, internalization of academic stress, and predisposition to low SES. This thesis summarizes research on the social determinants of anxiety for adolescent girls, utilizing a socio-ecological model and feminist research methods to …

Power, Pleasure, And Privilege: Defining Depauw’S Hookup Culture And Its Mental Health Implications, Reanna Stiehler '23

Honor Scholar Theses

Hookup culture is not primarily about sex, pleasure, connection, or freedom. Hookup culture is about power—how power is used, distributed, and desired. Previous work in hookup culture discusses a discourse of desire; however, the root and nature of this desire are unclear. I posit that hookup culture, as it currently exists, is strongly related to rape culture. In this thesis, I will explicate my anecdotal, qualitative, and quantitative evidence supporting this hypothesis.
