A Real-Time Approach To Capture Ambient And Focal Attention In Visual Search, Gavindya Jayawardena, Yasith Jayawardana, Yasasi Abeysinghe, Bhanuka Mahanama, Sampath Jayarathna, Jacek Gwizdka

Computer Science Faculty Publications

During visual search, individuals’ attention shifts between ambient and focal states in response to task demands and stimuli. The ambient/focal coefficient K is a statistically validated measure of these states, computed offline from fixation duration and saccade amplitude data. While current methods compute K offline, real-time computation could enable applications such as monitoring user attention, creating attention-adaptive user interfaces, and optimizing graphics rendering. However, real-time computation of K requires stable estimates for the parameters of fixation duration and saccade amplitude distributions. Since these distributions are heavy-tailed, the real-time estimates exhibit high variance and slow convergence. To overcome this, we propose …

Multi-Modal Mri Based Segmentation Of Brain Metastases Using Adaptive Self-Attention, Evan Savaria

Computer Science Faculty Publications

Brain metastases (BMs) are the most common adult central nervous system malignancy, affecting 20–40% of cancer patients. Accurate segmentation of metastatic lesions in multi-modal MRI is essential for treatment planning and prognosis however, manual delineation is time consuming and prone to variability. Traditional deep learning models such as U-Net, have improved segmentation accuracy but capture limited long-range dependencies and struggle with variations in metastasis size, shape, and distribution. This study introduces the Adaptive Integrated Multi-modal Segmentation (AIMS) model, an adaptive self-attention framework within a hybrid U-Net and Transformer architecture to enhance BM segmentation by leveraging multi-modal MRI integration. The proposed …

"Shocking The System" In The 21st Century: Conservative Policy Entrepreneurs And The Plan For Authoritarianism In The U.S., Athena M. King

Political Science & Geography Faculty Publications

The first few days of the second Trump presidency saw a flurry of executive orders targeting immigrants, the transgender community, blacks, and federal government employees. The resulting “shocks” to the system are unprecedented, causing many to question the continuation of American democracy. These actions are a few of many policy preferences developed by conservatives and captured in “Project 2025”, spearheaded by the Heritage Foundation and with the overall intent of restructuring the federal government to suit authoritarian aims. Using a theoretical framework regarding policy entrepreneurs (PEs), I argue that conservative PEs (CPEs), under the aegis of the Republican Party and …

Securitization Of African Migrants In Europe And North America, Chick Edmond

Political Science & Geography Faculty Publications

The securitization of African migrants in Europe and North America refers to the framing of immigrants as an existential security threat rather than a socioeconomic or humanitarian concerns. This discourse driven by political rhetoric, media narratives, and policy measures, often depict African migrants as risks to national security, cultural identity, and economic stability. Governments in host countries employ stringent border controls, detention and deportation policies often justified by counterterrorism and crime prevention frameworks. However, critics argue that securitization exacerbates xenophobia, violates human rights, and fails to address root causes of migration, such as conflict, poverty, and climate change. This paper …

Rethinking Trust In The Refugee Resettlement Process: How Service Providers Can Enable Refugee Agency Through Diasporic Connections, Mahfoudha Sidelemine, Emily D. Campion

Political Science & Geography Faculty Publications

Current guidance for refugee resettlement agency workers encourages the simultaneous pursuit of trust-building and administrative tasks (e.g., housing, transportation and employment). This dual goal is resource-intensive, and focusing on the former may come at a cost to the latter. The purpose of the current research is to challenge the importance of trust-building by resettlement agencies. Drawing from our qualitative data from in-depth interviews with resettled refugees (N = 20) and agency workers (N = 15), we adopt a grounded theory approach and find that the burden of responsibility for both caregiving and administrative responsibilities can overtax agency workers …

Manifesting A Shift In The "Overton Window": The Threat Of Project 2025 On The Lgbtq+ Community In Higher Education, Athena M. King, Sara Sanatkar

Political Science & Geography Faculty Publications

Since the first Trump administration, historically marginalized groups in the United States have been subjected to greater instances of bigotry and discrimination due to conservative influence on sociopolitical institutions. These actions suggest a shift in the "Overton Window," whereby policy preferences previously deemed "unacceptable" are given consideration in the mainstream, especially by conservative policy actors. "Project 2025" is a comprehensive plan to restructure the federal government according to conservative dictates in the second Trump administration. This article is an examination of how higher education may be impacted by this plan, especially as it relates to LGBTQ+ faculty, administration, staff, and …

Anhedonia Links Sleep Problems And Suicidal Thoughts: An Intensive Longitudinal Study In High-Risk Adolescents, Kinjal K. Patel, Jaclyn C. Kearns, Dan Foti, Wilfred R. Pigeon, Evan M. Kleiman, Catherine R. Glenn

Psychology Faculty Publications

Growing research indicates that sleep problems are a robust independent risk factor for suicidal thoughts and behaviors among youth. However, relatively little is known about how this risk is conferred. This study used an intensive longitudinal design to investigate anhedonia as a mechanism linking sleep problems and next-day suicidal thoughts in a clinically high-risk sample of adolescents. Adolescents (N = 48; M_age=14.96; 77.1% white, 64.6% female) completed an ecological momentary assessment (EMA) study design for 28 days following discharge from acute psychiatric care for suicide risk. Daily sleep diaries were used to assess prior night total sleep …

Influence Of Time Pressure And Flood Information Type On Flood Alert Effectiveness In Driving, Katherine R. Garcia, Scott Mishler, Jing Chen

Psychology Faculty Publications

Flood alerts are a means of risk communication that alerts the public to potential floods. The purpose of this research was to investigate factors that affected drivers' understanding and actions given a flood presented through a mobile navigation application. Two experiments were conducted to examine the effects of time pressure and type of flood information on drivers' planned actions when faced with potential flooding. Participants were asked about their planned actions given one type of flood information in a driving scenario either with or without time pressure. Our results indicated significant differences in participants' behaviors across the different flood information …

Approval Of Parent-Child Aggression As A Mediator Of Intergenerational Child Abuse Risk: An Evaluation Of Racial Differences, Casie H. Morgan, Christina M. Rodriguez, Doris F. Pu, Zoe O. Elkins

Psychology Faculty Publications

Purpose

Personal history of parent-child aggression (PCA) can predict future parenting behavior, but some effects may differ between racial groups. Black parents in the U.S. are more likely to encounter discrimination and personally experience and approve of PCA, which may account for previously reported group differences. This study examined whether personal PCA history predicted later parental child abuse risk mediated by PCA approval across the transition to parenthood, and whether effects differed by race.

Methods

Expectant parents (non-Hispanic White sample: 95 mothers with 86 fathers; Black sample: 94 mothers with 85 fathers) participated in a prospective longitudinal study, assessed prenatally …

Exploring Differences In Cannabis Use And Harm Perceptions Among Sexual Minority And Heterosexual Females: A Brief Report, Sarah J. Ehlke, Samantha A. Fitzer, Kendra Rigney

Psychology Faculty Publications

Objective: Sexual minority women (SMW) have higher rates of cannabis use compared to heterosexual women, which may be partially attributed to lower harm perceptions. However, no study has examined if the association between harm perceptions and cannabis use is stronger for SMW than heterosexual women. This study examined if sexual identity (SMW vs. heterosexual woman) moderated the association between harm perceptions and past 30-day cannabis use among a sample of female young adults (18-25 years old). Method: Participants were 949 (29.8% SMW; Mean age = 24.33; 92.1% non-Hispanic White) females (99.3% cisgender) recruited from Amazon Mechanical Turk who reported weekly …

Sounds Of Silence: Using The Stereotype Content Model To Understand Perceptions Of Introverts And Extraverts At Work, Mallory A. Mccord

Psychology Faculty Publications

This paper drew on the stereotype content model (SCM) to clarify cultural stereotypes about introverted and extraverted people at work to increase our understanding of the stereotype-driven process that may lead to negative responses to introversion and subsequent detriment to employee health and well-being. The hypothesis that introverted workers would be rated as lower in warmth and competence than extraverted workers was examined across three studies. Study 1 used qualitative content analyses to assess open responses that freely described introverted and extraverted colleagues. Study 2 tested the hypothesis quantitatively using established measures of warmth and competence. Finally, Study 3 tested …

Psychology Faculty Publications

Background: The accuracy of survey responses is a concern in research data quality, especially in college student samples. However, examination of the impact of removing participants from analyses who respond inaccurately or carelessly is warranted given the potential for loss of information or sample diversity. This study aimed to understand if careless responding varies across a number of demographic indices, substance use behaviors, and the timing of survey completion.

Method: College students (N = 5809; 70.7% female; 75.7% White, non-Hispanic) enrolled in psychology classes from six universities completed an online survey assessing a variety of demographic and substance use-related information, …

The Impact Of Peer Observational Learning On Honesty Following A Transgression, Hannah M. Sliman, George H. Noell

Psychology Faculty Publications

Parents and teachers worry about how lying affects children's development and socialization, as research links persistent lying to delinquency, aggression, and conduct issues. To investigate this, we examined two groups: Honest and Praise versus a Control Group, exploring how exposure influenced children's honesty and confession after transgressions. The study aimed to see if observing peers receive praise for honesty could promote truthfulness. Gender's impact on reporting honesty was assessed. Results showed no significant difference in honesty between the HP and CG groups; children confessed at similar rates in both conditions. Gender did not affect honest reporting. These findings differ from …

Family Stress Processes Underlying Covid-19-Related Economic Insecurity For Mothers And Fathers And Children's Internalizing Behavior Problems, Joyce Y. Lee, Shawna J. Lee, Sehun Oh, Amy Xu, Angelise Radney, Christina M. Rodriguez

Psychology Faculty Publications

COVID‐19 and its economic fallout have resulted in unprecedented financial insecurity and material hardship for many American families, with a disproportionately negative impact on children and families from socioeconomically disadvantaged contexts. The current study applied the family stress model to examine the family processes underlying pandemic‐related economic insecurity and children's internalizing behaviours. Online survey data from an economically diverse sample of mothers and fathers, who experienced at least one type of pandemic‐related economic insecurity in the United States (N = 259), were collected across two longitudinal time points in the early weeks of COVID‐19: (1) 14 April and (2) 30 …

Psychology Faculty Publications

Improving the health and well-being of pregnant adults is an important public health priority in the USA, and mobile health (mHealth) interventions may provide a scalable strategy to disseminate behavior change programs to pregnant adults. This study assessed pregnant people’s use of mobile technology, interest in making health behavior changes during and after pregnancy, and their willingness to use mHealth interventions. Participants were 133 pregnant adults (M_age = 27.86; 81% White) living across the USA recruited from social media to complete an online survey. Measures assessed mobile technology use and beliefs about improving mental/physical health in pregnancy and postpartum …

Brief Videos During Informed Consent May Be Helpful For Participants' Understanding Of Study Information, Abby L. Braitman, Rachel Ayala Guzman, Kristin E. Heron

Psychology Faculty Publications

Although an informed consent process is required for all research, it is not clear how well study participants read informed consent forms and understand their content. A systematic review of medical clinical trials revealed participants had only a 50% rate of understanding for concepts of the consent process, including voluntary participation, blinding, and freedom to withdraw, with lower rates for randomization, risks, and safety issues (Pietrzykowski & Smilowska, 2021). This issue may be more pronounced for online research, with a recent study indicating half of participants report not reading informed consent forms at all (Perrault & Keating, 2017). Although increasing …

Identifying Salient Social, Environmental, And Situational Contexts Of College Drinking: Impacts Across Drinking Outcomes, Abby L. Braitman, Jennifer L. Shipley, Megan Strowger, Emily S. Renzoni

Psychology Faculty Publications

Background and Objectives: Drinking context, such as where, why, and under what social conditions drinking occurs, is consistently associated with daily variability in alcohol use. However, ecological momentary assessment (EMA) requires very brief measurement, not allowing for as many contextual assessments as researchers may like. The current investigation examined common contextual predictors and their associations with different alcohol outcomes.

Methods: A sample of N=528 college drinkers completed three surveys about their most recent drinking episode. This included contextual predictors (location, social context, who was present, alcohol offers, and drinking motives), as well as typical drinking outcomes (number of drinks, estimated …

Evaluation Of A 20-Item Version Of The Trauma-Related Drinking To Cope Questionnaire, Sage E. Hawn, Lauren Smith, Kaytlin Armitage, Selah Ball, Cathy Lau-Barraco, Abigail Powers, Ananda B. Amstadter

Psychology Faculty Publications

Objectives: This study sought to develop and psychometrically evaluate an expanded version of the Trauma-Related Drinking to Cope (TRD) scale, a four-item self-report tool, which was developed to address a crucial gap in self-medication research. Before the development of the TRD, no measures existed which assessed alcohol use for coping with symptoms of posttraumatic stress disorder (PTSD) specifically. Previous work showed that the TRD has strong psychometric properties and clinical utility in its ability to identify individuals with PTSD who may be at risk for developing comorbid alcohol use disorder (AUD). The aim of the present study was to develop …

Graduate And Undergraduate Quantitative Education In Psychology In The United States: A Mixed Methods Approach, Abby L. Braitman, James M. Henson

Psychology Faculty Publications

Quantitative methodology is part of the core curriculum for training in psychology and is required of graduate students across all subdisciplines; as such, the depth and breadth of course content is a universal issue among psychology training programs. Required and supplemental quantitative content is constantly evolving with the development of new techniques or applications. Therefore, the purpose of this inquiry was fourfold; we aimed to (1) describe the current state of undergraduate quantitative education and establish a common set of current undergraduate curricular topics; (2) characterize graduate quantitative education in terms of required coursework, optional coursework, and omitted topics; (3) …

Vagally Mediated Heart Rate Variability Modulates The Association Between The Perceived Workload And The Stroop Effect On Behavioral Performance, Xiao Yang, Michael Gazzanigo, Fang Fang, Spencer House

Psychology Faculty Publications

Vagally mediated heart rate variability (vmHRV) reflects top-down cognitive processes involved in emotion-cognition integration. Using cognitive control can be effortful and increase negative affect. However, this intrinsic affective component of cognitive control has not been well studied, and the role of vmHRV in the association between subjective experience in using cognitive control and behavioral performance remains unknown. The current study aimed to examine the relationship of vmHRV with cognitive control and perceived workload in a cognitive task. Eighty-one participants performed the Stroop interference task. Participants rated subjective workload using the NASA Task Load Index (NASA-TLX) scale for congruent and incongruent …

Psychology Faculty Publications

Background

Long-acting injectable pre-exposure prophylaxis (LAI-PrEP) for HIV prevention may improve adherence for those with concerns with daily pills. Limited data exist on LAI-PrEP acceptability among Black women in the U.S., a population vulnerable to HIV. We assessed willingness to use LAI-PrEP among Black women eligible for PrEP in the Southern U.S.

Methods

We conducted a cross-sectional online survey of HIV-negative Black women from March to June 2022 in the U.S. South. Participants provided information on sociodemographic characteristics, HIV knowledge, PrEP awareness, and use, stigma, risk perception, medical mistrust, and healthcare access. Multivariate logistic regression models determined factors associated with …

The Perceived Internalized Sexual Stigma Measure (Prissm): A New Sexual Stigma Measure For Lesbian, Gay, And Bisexual Individuals, Miguel A. Padilla, Lacey M. Schlappi, Evelyn S. Chiang

Psychology Faculty Publications

Society has long held negative beliefs and attitudes, in the form of sexual stigma, towards sexual minorities (e.g., lesbian, gay, and bisexual; LGB). Sexual stigma can be adopted and internalized by LGB individuals as their own beliefs and attitudes. In LGB individuals, internalized sexual stigma can result in psychological distress such as low self-esteem, depression, shame, and feelings of rejection. However, an instrument to assess internalized sexual stigma specifically developed for LGB individuals is lacking. The present study focuses on the development of a new instrument, the Perceived Internalized Sexual Stigma Measure (PrISSM), that is inclusive of LGB individuals who …

Am I As Effective At Identifying Emotions As Artificial Intelligence? A Comparative Study Of Emotional Recognition, Traci R. Grove, Alexandra T. Lucas, Maryann Martin, Cathleen M. Deckers, Lulu Sherif Mahmood, Nicole Danaher-Garcia, Mark W. Scerbo, Suzan Kardong-Edgren, Janice C. Palaganas

Psychology Faculty Publications

Background

Learning conversations, or dialogues aimed at deepening understanding and reflection, are deeply influenced by emotions. Effective communication is influenced by emotional intelligence - the ability to recognize, understand, and manage both one’s own and others’ emotions. While advances in artificial intelligence (AI) offer new tools for emotion recognition, these technologies still struggle with accurately interpreting subtle and culturally diverse emotional expressions, sparking debate about their reliability and effectiveness. This article provides a comparative analysis of human versus AI recognition of emotions during an end-of-course reflective learning conversation.

Methods

Emotions during a structured post-conference debriefing were analyzed and coded by …

Parent Ptsd, Social Support And Differential Associations With Facets Of Anxiety Sensitivity, Kristen Bermingham, Christopher Latourrette, Karen G. Chartier, Spit For Science Working Group, Ananda B. Amstadter, Kaitlin Bountress

Psychology Faculty Publications

Background: Anxiety Sensitivity (AS), the belief that anxiety experiences have negative implications, is a prospective predictor of posttraumatic stress disorder (PTSD) and has been linked to changes in PTSD in experimental studies. AS is comprised of three sub-components: cognitive, physical, and social concerns. PTSD is moderately heritable and parental PTSD may increase risk for these AS facets both directly and through environmental influences like reduced social support.

Objective: The present study will examine whether Parent PTSD is associated with reduced social support and in turn facets of AS.

Method: Participants were recruited from an ongoing longitudinal study of college student …

Automation To Autonomy: Temporal Dynamics Of Trust And Visual Attention Allocation Did Not Evolve, Tetsuya Sato, Eric Chancey, Yusuke Yamani

Psychology Faculty Publications

Emerging work environments are expected to implement autonomy that performs various functions without human input. Previous works has shown that trust in automation is negatively correlated with visual attention allocation, indicating that trust is a dynamic construct. Moreover, trust in automation and trust in autonomy appears to evolve in similar ways. However, recent work has demonstrated differences between trust in automation and trust in autonomy within Kaber’s (2018) theoretical framework (Sato et al., 2023b). Yet, it is uncertain whether the development of trust and visual attention allocation differs between automation and autonomy. The present study examined the temporal dynamics of …

Cellphone Separation Modulates The Effects Of Working Memory Load On Ex-Gaussian Parameters Of Choice Reaction Time, Michael Gazzanigo, Alexa Quesnel, Catalina Roldan, Xiao Yang

Psychology Faculty Publications

Cognitive effects of cellphone dependency among young adults have garnered increasing research attention. While cellphones have been identified as a distractor in daily tasks, related psychological processes remain unclear. As a potential mechanism underlying those effects of cellphones, excessive working memory (WM) load has not yet been well examined. Our study investigated the effects of the mental representation of cellphone separation on WM. Seventy-five participants (M(age) = 21.3 years; 55 females, 20 males) were assigned into three groups: the cued separation, natural separation, or control group, and completed a block of choice reaction time (CRT) task, and a dual-task block: …

A Multilevel Framework For The Promotion Of Maternal Mental Health And Well-Being During The Perinatal Period, Jenn A. Leiferman, Jessica Walls Wilson, Charlotte V. Farewell, Chelsea Walker-Mao, James F. Paulson

Psychology Faculty Publications

Background: Depression and anxiety are prevalent in the perinatal period and may contribute to adverse maternal and child health outcomes. A focus on multilevel protective factors may be effective in promoting well-being and increasing quality of life (QOL) in the perinatal period while simultaneously reducing or preventing depression and anxiety symptoms. We tested a conceptual model that posits specific personal, social, and community factors affecting depression, anxiety, and QOL among pregnant and postpartum individuals.

Methods: Four hundred and thirty-eight pregnant or postpartum individuals completed a 121-item cross-sectional survey composed of validated tools that assessed multilevel protective factors, health behaviors, and …

Similarity May Be Safer: The Effect Of Similarity Between Speech-Based Takeover Request Style And Driver Personality On Self-Driving Takeover Performance, Keer Ma, Jianfeng Wu, Yanxi Lin, Zihan Li, Songyang Guo, Dongfang Jiao, Shihan Yu

Psychology Faculty Publications

In Level 3 automated driving, it is critical that drivers can rapidly and effectively shift from non-driving related tasks (NDRT) back to the driving task. While previous research has examined the modality, timing, and vocal characteristics of takeover requests (TORs), little is known about how the style of speech-based TORs interacts with drivers’ personality traits. This study conducted a driving simulator experiment with 49 participants using a 2 × 2 within-subjects design. Drawing on the dominant-submissive dimension of personality, we examined the similarity of personality tendencies between speech-based TORs and drivers under takeover scenarios of varying urgency (low: road construction; …
