Living In A Bubble: How Children And Adults Use Generics To Talk About Social Kinds In Unique Sociocultural Contexts, Ny Vasil, Alejandro Curiel, Tiffany Zhu, Anna Pederneschi, Katherine Ritchie

Philosophy Faculty Publications

Generics like "kids love sugar" convey generalizations. But what is their scope? Are they taken to be global, or can generics communicate regularities restricted to "sociocultural bubbles"? Two studies examined the developing capacity for contextual restriction of generics in 137 4-7-year-olds (63/70/4 female/male/other) and 222 adults (128/89/5 female/male/other). Participants evaluated generics attributing group properties prevalent globally vs. "within-bubbles," with contextual cues that speakers conveyed broad vs. contextually restricted regularities. Both children and adults appreciated that generics can communicate group characteristics occurring within narrow sociocultural contexts. Adults selectively endorsed global or local generics depending on context, but younger children allowed socially …

[Review Of The Book The Prescription-To-Prison Pipeline: The Medicalization And Criminalization Of Pain, By M. Smirnova], Hayley Jackey

Sociology & Criminal Justice Faculty Publications

[Introduction] Smirnova’s The Prescription-to-Prison Pipeline offers a critical examination of the impacts of prescription drugs as well as the over-policing and policies created to push individuals into the carceral system rather than providing other options for assistance. Smirnova further captures the social inequalities of race and class of those encased in this pipeline. Within this understanding of the detriment that the system, medical providers, and society place on those who use substances, Smirnova’s use of interviews allows for a clear understanding of how these systems work in conjunction to uphold the pipeline.

Eeg Signatures Of Motor Development In Early Childhood: A Systematic Review, Sonia Khurana, Ashwini Kulkarni, Thomas C. Bulea, Hunter J. Bennett

Rehabilitation Sciences Faculty Publications

Background

Early identification of motor developmental disorders is limited due to lack of objective neural markers that characterize typical neurodevelopmental patterns. This systematic review interprets and synthesizes existing evidence to propose a framework of EEG signatures associated with motor development in children aged 0-5 years, which may help inform future benchmarks for early assessment and intervention.

Methods

Following PRISMA guidelines, we searched published and gray literature across five databases between 2000 and 2025 (registered protocol). Included studies examined EEG during task-based, resting-state, or sleep studies linked to motor milestones, task performance, or standardized motor assessments. Study quality was assessed using …

Seeing The Invisible Load: Xr+ Multimodal Sensing For Cognitive Ergonomics In Industrial Training, Jessica M. Johnson, Andwele Grant

Virginia Digital Maritime Center (VDMC) Faculty Publications

Extended reality (XR) technologies are increasingly positioned as disruptive Industry 5.0 tools for human-centric industrial training and intelligent human–system integration. Coupled with multimodal sensing (eye tracking, EEG, HRV, GSR, and other physiological signals), XR environments promise to make otherwise invisible cognitive demands observable, especially for novice trainees entering complex industrial settings. Yet the evidence base is fragmented: (1) there is no quantitative synthesis of the cognitive ergonomics benefits of XR plus sensing; (2) little is known about which XR–sensor configurations yield the strongest effects; (3) prior reviews rarely focus on industrial and manufacturing tasks; (4) multimodal signals are used predominantly …

Improving Pediatric Emergency Department Lethal Means Safety Documentation Rates For Adolescents With Mental Health Concerns, Cassandra L. Stegall, Ana-Maria Mcgill, John Fanton, Paul C. Mullan

Department Psychiatry & Behavioral Science Faculty Publications

Introduction:

Lethal means safety counseling (LMSC) is recommended for children presenting to the emergency department (ED) for a mental health (MH) evaluation. Currently, no gold-standard guidelines exist for documenting LMSC in the ED.

Methods:

This quality improvement project was conducted in the ED of a tertiary children's hospital. Baseline data were analyzed for access to any LMSC documentation (ALD) for "firearms/guns," "sharps," or "medication," and for complete LMSC documentation (CLD) if access to all 3 types was documented. The first intervention period added open-ended screening questions about access to lethal means to the MH-licensed clinical social worker note template. Intervention …

Startle Habituation And Vagally Mediated Heart Rate Variability Influence The Use Of Emotion Regulation Strategies, Xiao Yang, Fang Fang, Angela Ximena Babb

Psychology Faculty Publications

Emotion regulation refers to the processes through which people modulate their emotional experiences and expressions, and difficulties in these processes underpin many forms of psychopathology. According to the process model, emotion regulation encompasses five classes of strategies, commonly grouped into antecedent-focused strategies (e.g., cognitive reappraisal) and response-focused strategies (e.g., expressive suppression). These strategies involve both explicit and implicit processes, which can be objectively assessed using physiological indices. The present study examined the effects of startle habituation and vagally mediated heart rate variability (vmHRV) on the use of cognitive appraisal and suppression. Forty-nine college-aged participants were recruited, and their resting heart …

Gaze Transition Entropy And Automation Trust In Multitasking Workspace, Yusuke Yamani, Austin Jackson, Tetsuya Sato, Feyishola Ashimi, Michael S. Politowicz, Eric T. Chancey, Makoto Itoh

Psychology Faculty Publications

Safe flight operation requires visual scanning across multiple displays in a cockpit, which collectively represent the state of the aircraft and supporting automation. Trust is a crucial factor that drives human-automation interaction, and recent work has suggested a relationship between an operator's visual attention and automation trust. One index that captures predictability of eye movements between different areas of interest is gaze transition entropy. The current work reanalyzed data from Sato et al., which examined eye movement patterns and trust in automation associated with the system monitoring task of the Multi-Attribute Task Battery. Results showed credible positive correlations between the …

Parental Psychological Distress And Perceived Child Externalizing Behaviors: Examining Mediators And Bidirectional Effects, Abigail J. Anderson, Christina M. Rodriguez, James M. Henson

Psychology Faculty Publications

Parental psychological distress is a commonly examined risk factor for the emergence of child problem behaviors, but the factors that contribute to that relationship—such as limited parental resources like greater social support and coping skills—have not been adequately explored, particularly with attention to potential bidirectional relations that incorporate child evocative effects. The current longitudinal study examined maternal and paternal psychological distress in relation to perceived child externalizing behaviors, considering parental resources as mediators within a bidirectional model. The sample included a racially and socioeconomically diverse group of 201 primiparous mothers and 151 fathers. Mothers and fathers reported their current psychological …

I Can't Stop: The Effects Of Psychological Climate For Overwork On Recovery Experiences, Jeffrey Drake Terry, Konstantin P. Cigularov

Psychology Faculty Publications

Recovery experiences are important for many health and well-being outcomes. One potential threat to an individual's recovery experiences in the workplace is psychological climate for overwork. The purpose of the present study was to examine the relationship between psychological climate for overwork and recovery experiences. Using a multi-wave research design (N = 202), we found that psychological climate for overwork had direct effects on psychological detachment and indirect effects on psychological detachment and relaxation through cognitive workaholism and work-recovery guilt. These results suggest that psychological climate for overwork may contribute to an individual's experience of cognitive workaholism and work-recovery guilt, …

Maternal Child Maltreatment And Intimate Partner Violence: Effects On Perceptions Of Infant Temperment And The Mediating Role Of Emotion Regulation And Responsiveness, Jewelian N. Fairchild, G. Anne Bogat, Amy K. Nuttall, Alytia A. Levendosky, Joseph S. Lonstein, Maria Muzik

Psychology Faculty Publications

Purpose

Maternal adverse experiences, such as maltreatment in childhood and later intimate partner violence (IPV) during pregnancy, can disrupt the mother-child relationship and influence maternal perceptions of infant temperament. The present study explored how these adversities influence mothers’ views of their infants’ temperaments and examined the role of maternal emotion regulation and responsiveness to their infants as mediators of these relationships.

Methods

Using data from a longitudinal study of highly stressed, vulnerable women, 355 mothers retrospectively reported on their own childhood maltreatment, as well as their experiences of IPV and emotion regulation during pregnancy. Maternal responsiveness was coded using mother-infant …

From Molecules To Minds: Integrative Multi-Omics In Psychiatry, Hossein Abbasi, Sage E. Hawn, Arash Javanbakht, Soraya Seedat, Kyle Bourassa, Sinead M. Sinnott, Antonia V. Seligowski, Sian Hemmings, Nathan A. Kimbrel, Alicia K. Smith, Leslie Brick, Divya Mehta

Psychology Faculty Publications

Psychiatric disorders are biologically complex conditions arising from interactions across genomic, epigenomic, transcriptomic, proteomic, metabolomic, and metagenomic layers. Single-omics approaches rarely capture more than a fraction of the variance in complex conditions, underscoring the importance of integrative multi-omics frameworks. This mini-review summarizes key methodologies and their application in psychiatric research, with a focus on systems-level integration of genomic risk scores, transcriptomic networks, and neuroimaging data to advance biological understanding of disorders such as depression, schizophrenia, and Alzheimer’s disease. We also outline the infrastructural requirements for effective multi-omics research, including standardized biobanking, Laboratory Information Management Systems, adherence to FAIR data principles, …

Advancing Models Of Ptsd-Aud Comorbidity: Protocol For A Multimethod Framework Using Genetics And Ecological Momentary Assessment, Elizabeth A. Stinson, Samhita Lellapalli, Sage E. Hawn, Natalie Merrill, Lance M. Rappaport, Christina M. Sheerin, Vasiliki Michopoulos, Silviu-Alin Bacanu, Roseann E. Peterson, Abigail Powers, Ananda B. Amstadter

Psychology Faculty Publications

Background: Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD), which are moderately heritable, frequently co-occur and contribute to significant public health burdens, particularly among economically disadvantaged urban communities. There are noted sex differences in PTSD and AUD outcomes, with evidence suggesting women have heightened susceptibility to stress-related alcohol use. Preliminary PTSD-AUD ecological momentary assessment (EMA) findings support bidirectional associations across clinical outcomes. However, no studies to date have used PTSD-AUD comorbidity models as organizing frameworks to examine the temporal ordering and stability of within-person symptom dynamics underlying the maintenance or exacerbation of PTSD and AUD symptoms, including bidirectional and …

Establishing Hierarchical Classification Responding: Directly Trained And Emergent Responses, George H. Noell, Kristin A. Gansle, Hannah M. Sliman, Danielle M. De Lucia

Psychology Faculty Publications

Hierarchical classification responding (HCR) describes a collection of responses that require discrimination of logical relationships between stimuli based on their position in a categorical hierarchy. This study established HCR for a new hierarchy in young children through discrete trial instruction. Participants selected pictures corresponding to different hierarchical levels of categorization. We tested for the emergence of naming that matched the level of hierarchy presented, transformation of function, and class inclusion responding for the trained and novel stimuli. Correct responding to the target hierarchy was established and resulted in the emergence of class naming and transformation of function without direct instruction. …

A Real-Time Examination And Comparison Of Differentiation Among Suicidal Thinking And Affect Items In An Adolescent Sample, Elizabeth A. Edershile, Kinjal K. Patel, Annabelle M. Mournet, Richard T. Liu, Catherine R. Glenn, Evan M. Kleiman

Psychology Faculty Publications

Suicide risk assessments require individuals to differentiate among types of suicidal thoughts (e.g., passive vs. active); yet most research relies on aggregate metrics that obscure this differentiation. Indeed, more severe forms of suicidal thinking are thought to involve the simultaneous experience of multiple forms of thoughts at high intensities. The present study draws on concepts from the affect differentiation literature to (a) examine different ways to operationalize differentiation in suicidal thinking and (b) compare differentiation in suicidal thinking with differentiation in affect. Adolescents (N = 200) recently hospitalized for suicidal thoughts and behaviors completed a 28-day ecological momentary assessment …

Examining The Factor Structure And Subgroup Invariance Of The Deliberate Denial Of Disordered Eating Behaviors Scale, Lindsay Howard, Sage Hawn, Kayla D. Pitchford, Riley Mcgrath, Aubri Farniok, Arturo Sesma, Kristin E. Heron

Psychology Faculty Publications

The denial, concealment, or omission of disordered eating behaviors has received limited attention in the eating disorder literature, partly due to the lack of reliable and valid measures. This study re-examined the factor structure of the Denial of Disordered Eating Behaviors Scale (DDEBS-12) and tested measurement invariance across gender identity, racial identity, and levels of disordered eating in a non-clinical undergraduate sample (N = 3285). Confirmatory factor analyses did not support the original unidimensional structure. Instead, a seven-item model assessing denial of dietary restriction demonstrated the best fit and was renamed the DDEBS-restriction. The revised scale showed good internal consistency …

Rude Awakening: An Examination Of The Incivility-Sleep Relationship Via Affect, Mallory A. Mccord, Gargi Sawhney, Nastassia M. Savage, Kristen M. Fisher

Psychology Faculty Publications

Despite the prevalence of incivility at work and the essential nature of sleep, study of this relationship is comparatively sparse in the organizational sciences literature. Further, although impaired sleep could logically impact how one interprets subsequent interpersonal interactions at work, the dominant approach is to study sleep as an outcome of perceived incivility. Therefore, we drew upon affective events theory, the affect-as-information hypothesis, and sleep physiology to argue that state affect, both positive and negative, can explain the relationship between perceived incivility and sleep quality in either direction. The hypotheses were tested using a between-subjects design with one-month time lags …

Best Practices For Using Biological Data In Psychological Research, Sage E. Hawn, Sinead M. Sinnott, Alicia K. Smith, Kyle Bourassa, Leslie Brick, Sian Hemmings, Soraya Seedat, Arash Javanbakht, Lauren Smith, Antonia V. Seligowski, Nathan A. Kimbrel, Divya Mehta, Hossein Abbasi, Erika Wolf

Psychology Faculty Publications

Advances in statistical techniques for analyzing biological data have driven the need for larger sample sizes, which are ultimately made possible through team science efforts. Findings from these efforts have led to a significant shift in approaches to biological data collection over the past decade, from traditional approaches relying on single measures or assays collected by individual investigators in small lab-based studies to high-dimensional methodologies embedded within large cohorts or multi-site studies. These recent large scale consortium efforts necessitate careful consideration across the full data pipeline, from pre-data generation and sample collection to processing and statistical analysis, while addressing challenges …

Comparison Of Mental Illness Comorbidity Pre-Pandemic Vs. Pandemic-Era And Associations With Clinical And Demographic Characteristics For Virginia Public Hospital Inpatient Discharges With A Substance Use Disorder, Marilyn Bartholmae, Tharidu Gunawardena

Department of Medicine Faculty Publications

The rise in mental illnesses after the COVID-19 pandemic is well documented. However, it is not known whether the rates of mental illness comorbidity increased. The objectives of this study were to compare mental illness comorbidity rates before and after the pandemic among inpatients with SUD and to test associations between mental illness comorbidity, physical illness, and demographics. We used a retrospective cross-sectional design in a sample of inpatient discharges (N = 233,017) at Virginia public hospitals from January 2018 to December 2022. We used Z tests to compare rates of mental illness comorbidity pre- and post-pandemic and Chi-square tests …

Persistent Peristomal Pain Due To An Exposed Cutaneous Nerve, Iain Noel Encarnacion, Kaylin Beiter, Natasha Hakkal, Emily Hejazi, Paul Hernandez, Melissa Laughter, Shannon Nugent, Samir Thaker, Xiaowei Xu, Misha Rosenbach

Department of Medicine Faculty Publications

[Introduction]

Case description

A 25-year-old woman with a history of ulcerative colitis treated with multiple abdominal surgeries complicated by peristomal pyoderma gangrenosum (PPG) presented with severe peristomal pain and ulceration. Treatment course was complicated; disease control was achieved via combination infliximab 10 mg/kg every 4 weeks, corticosteroids (topical triamcinolone 0.1% ointment, intralesional 10 mg/ml injections, and oral prednisone 30 mg daily with a gradual taper), and cyclosporine 125 mg tapering by 25 mg every 3 weeks, ultimately tapered to infliximab monotherapy.

Steady As She Goes: Remote Work Benefits Daily Goal Progress Through Reduced Energy Variability, Andrew A. Bennett, Kathleen R. Keeler, Emily D. Campion, Sheila K. Keener

Management Faculty Publications

As the prevalence and allowance of remote and hybrid work evolves, research has shown consistently mixed findings about how work location is related to worker energy and perceptions of daily performance. We aim to resolve this ambiguity by integrating affective events theory with ideas about emotion dynamics to develop new theorizing explaining why energy variability, rather than mean energy level, is an important predictor of daily goal progress. We test our hypotheses using a sample of 219 employees from one organization allowing remote and hybrid work, capturing individual hourly energy levels for five consecutive workdays (4,812 hourly observations). Our …

Professional Standards For School-Based Behavior Analysts (2nd Edition), Selena J. Layden, Emily Muise, Karen L. Berlin, Samantha Gregory, Daniel Irwin, Kaylan Long, Daria K. Lorio-Barsten, Jennifer L. O’Berry, Hannah Riddle

Human Movement Studies & Special Education Faculty Publications

Public educational settings are unique and complex environments that require specific knowledge and skills for the professionals that work in these environments. School-based behavior analysts can be a great asset to public schools. However, these professionals must be able to firmly understand and perform the responsibilities of a behavior analyst in collaboration with educators and service providers in a public school setting. The presence of behavior analysts in public schools is still relatively new, when compared with other specialized services. Therefore, behavior analysts, teachers, administrators, and others should focus on collaboration to promote the success for all stakeholders with an …

An Insidious Interstice: Understanding Cognition And Language Behaviour Through The Eyes Of Juvenile Justice Professionals, Anne M. Perrotti, Allison T. Chappell, Tancy Vandecar-Burdin

Human Movement Studies & Special Education Faculty Publications

Introduction

Despite evidence suggesting language and cognition deficits are prevalent for justice involved youth, little research explores how juvenile justice personnel experience language and cognition behaviours in the youth they serve.

Aims

This qualitative study explored how juvenile justice personnel understand language and cognition skills and deficits in justice involved youth.

Methods

Twenty-two U.S. juvenile justice professionals participated in individual, semi-structured interviews. Questions focused on individual understanding of receptive language, expressive language, social communication, and cognition (i.e., problem-solving, predicting consequences and impulsiveness) in juveniles served. Using a phenomenological lens, transcripts were coded identifying themes and sub-themes of participant responses.

Results …

The Relationship Between Physical Activity, Sleep, And Hallucinations In Adults With Charles Bonnet Syndrome, Jarrod Hollis, Rohit Narayan, Eldre W. Beukes, Rosie Lindsay, Aliyah Bharwani, Umair Mughal, Ikra Yaqoob, Justin A. Haegele, Scott Muriden, Peter M. Allen

Human Movement Studies & Special Education Faculty Publications

Physical activity levels, hallucination experiences, sleep quality, and perceived stress were assessed using a survey administered to 57 adults with a confirmed diagnosis of Charles Bonnet Syndrome (CBS). Physical activity demonstrated a significant negative correlation with hallucination severity (r = –0.335, p = 0.011, two-tailed). A significant negative correlation was also observed between physical activity and perceived stress (r = –0.497, p < 0.001, two-tailed). In contrast, no significant association was identified between hallucination frequency and sleep disruption or insomnia. These findings suggest that engaging in appropriate levels of physical activity may help reduce the severity of hallucinations and mitigate stress among individuals with CBS. The observation that higher levels of physical activity are associated with reduced hallucination burden may help the development of evidence-based management strategies for CBS. Additionally, the finding that physical activity was significantly related to hallucination severity, whereas sleep disruption was not, merits deeper exploration in future research.

Joint Associations Of Meditation And Physical Activity With Depression And Anxiety Symptoms In Us Adults: Nhis 2022, Yubing Wang

Human Movement Studies & Special Education Faculty Publications

Objectives

Physical activity and meditation may each relate to mental health, but their joint associations in U.S. adults are unclear. We examined the separate and joint associations of any past-year meditation and meeting physical activity (PA) guidelines with depression and anxiety symptoms.

Method

We analyzed data from the 2022 National Health Interview Survey Sample Adult file (n = 24,927). Exposures were meeting PA guidelines, any past-year meditation, and their four-level combination (Neither, PA only, Meditation only, Both). Outcomes were moderate-to-severe depressive and anxiety symptoms (PHQ-8/GAD-7 >= 10). Survey-weighted modified Poisson models estimated prevalence ratios (PRs), with interaction, sensitivity, and post …

Chronic psychosocial stressors contribute to cardiovascular disease (CVD) and related risk factors, particularly in under-resourced communities. Psychosocial stressors activate the hypothalamic-pituitary-adrenal (HPA) axis, leading to sustained cortisol action on immune cells. Natural killer (NK) cells are altered in distribution and function in cardio-metabolic diseases; however, pathways linking cortisol as a marker of chronic stress to NK cell dysfunction remain understudied. We recruited 186 African American women from the Step It Up Community-Engaged, Digital Health Physical Activity Intervention study and collected cortisol, NK cell measures, and psychosocial stress measures using validated questionnaires, including chronic stress and loneliness. Plasma cortisol levels were …

Susceptibility To High-Fidelity Misinformation: An Eye-Tracking Analysis, Yasasi Abeysinghe, Gavindya Jayawardena, Enkelejda Kasneci, Sampath Jayarathna

Computer Science Faculty Publications

With the rise of online misinformation and AI-generated text, understanding human perception of news truthfulness is critical. In this study, we examine visual attention and cognitive processing using eye-tracking measures as individuals read fake and real news articles sharing nearly identical structure and imagery, differing only in subtle textual changes. Using the public FakeNewsPerception dataset, we analyze advanced gaze measures, including scanpaths, AOI transitions, and luminance-corrected pupil measures, beyond basic gaze features, in relation to news truthfulness and perceived believability. Results show that, given the high fidelity of the fake news, readers exhibited comparable visual scanning patterns, attention allocation across …

Modeling Joint Visual Attention In Naturalistic Dyadic Interactions, Kuushini Thennakoon, Yasasi Abeysinghe, Bhanuka Mahanama, Vikas Ashok, Sampath Jayarathna

Computer Science Faculty Publications

Joint visual attention (JVA) provides important insight into how individuals coordinate attention during social interaction. Egocentric eye tracking enables the study of JVA in natural, multi-user settings. This work presents a multi-stage framework to identify and analyze JVA using egocentric video and gaze data. The approach consists of three steps: spatiotemporal tube-based visual similarity, gaze-guided object detection, and attention pattern analysis using the ambient–focal coefficient K. Results show that object-focused collaborative activities exhibit high JVA, with object detection capturing higher joint attention than visual similarity, whereas conversation-based or independent activities show lower and more fragmented joint attention. Analysis of K …

Unraveling The Links Between Substance Use And Academic Motivation In Higher Education, Melissa Lynn Goins

STEMPS Theses & Dissertations

Self-Determination Theory (SDT) posits that the quality of students’ motivation regulation (i.e., autonomous versus controlled) shapes both learning and health behavior, yet few studies have examined the relations among motivation regulation, alcohol and cannabis use, and achievement. In this study, I surveyed 459 undergraduates at a mid-sized public university in the southeastern United States. Participants completed the Academic Motivation Scale-College version 28 to assess autonomous and controlled motivation regulation, a typical-week alcohol grid, a seven-day cannabis grid, and self-reported grade point average (GPA). Results indicated that autonomous academic motivation was uniquely related to GPA; however, neither motivation variable related to …
