Background Latina mothers have been especially affected by the pandemic and historically exhibit high rates of depression and anxiety. However, few longitudinal studies have assessed the effect of the pandemic on this vulnerable population. We hypothesized that COVID-19-related stressors would associate with psychological distress among Latina mothers across the first year of the pandemic.

Methods We investigated COVID-19-related impact, stigma, and fears across two critical time points and changes in these measures in relation to changes in maternal anxiety and depression among mothers of Mexican descent living in Southern California (n=152). Surveys were administered within 5–16 weeks of …

Background

Conduct disorder (CD) involves a group of behavioral and emotional problems that usually begins during childhood or adolescence. Structural brain alterations have been observed in CD, including the amygdala, insula, ventrolateral and medial prefrontal cortex, anterior cingulate cortex, and fusiform gyrus. The current study developed a multivariate generalized linear model (GLM) to differentiate adolescents with CD from typically developing (TD) adolescents in terms of grey matter volume (GMV).

Methods

The whole‐brain structural MRI data were collected from 96 adolescents with CD (mean age = 16.188 ± 1.259 years; mean IQ = 104.292 ± 8.107 ; 63 males) and 90 …


Specialized Late Cingulo-Opercular Network Activation Elucidates The Mechanisms Underlying Decisions About Ambiguity, Jordan E. Pierce, Nathan M. Petro, Elizabeth Clancy, Caterina Gratton, Steven E. Petersen, Maital Neta Oct 2023

Specialized Late Cingulo-Opercular Network Activation Elucidates The Mechanisms Underlying Decisions About Ambiguity, Jordan E. Pierce, Nathan M. Petro, Elizabeth Clancy, Caterina Gratton, Steven E. Petersen, Maital Neta

Center for Brain, Biology, and Behavior: Faculty Publications

Cortical task control networks, including the cingulo-opercular (CO) network play a key role in decision-making across a variety of functional domains. In particular, the CO network functions in a performance reporting capacity that supports successful task performance, especially in response to errors and ambiguity. In two studies testing the contribution of the CO network to ambiguity processing, we presented a valence bias task in which masked clearly and ambiguously valenced emotional expressions were slowly revealed over several seconds. This slow reveal task design provides a window into the decision-making mechanisms as they unfold over the course of a trial. In …

One Size Doesn’T Fit All: Attitudes Towards Work Modify The Relation Between Parental Leave Length And Postpartum Depression, Christine Y. Chang, Sabrina R. Liu, Laura M. Glynn

Psychology Faculty Articles and Research

The present study aimed to investigate the relationship between parental leave length and maternal depressive symptoms at six- and twelve-months postpartum and whether this relation was influenced by women’s attitudes towards leave, whether leave was paid or unpaid, and the reason they returned to work. The sample included 115 working women recruited during pregnancy as part of a larger longitudinal study. Analyses revealed that maternal attitudes toward leave influenced the association between leave length and depressive symptoms. Specifically, longer leaves were associated with increased depressive symptoms for women who missed their previous activities at work. Furthermore, women who missed work …

Making Mindfulness More Accessible: A Practical Guide To Trauma-Informed Mindfulness, Leslie Formby Sep 2023

Making Mindfulness More Accessible: A Practical Guide To Trauma-Informed Mindfulness, Leslie Formby

Mindfulness Studies Theses

Mindfulness is currently embedded in a growing understanding of how trauma permeates and adversely impacts peoples’ physical and psychological well-being. Increased awareness of the prevalence of trauma and its harmful effects has led to renewed interest in mindfulness to help manage the challenges generated by the detrimental effects of trauma.

These effects may draw people to mindfulness and, in turn, may make the benefits of mindfulness out of reach. Mindfulness methods and practice adaptations have been found to help trauma survivors experience the benefits of what the Buddha taught. As a support for those engaging in mindfulness and meditation, this …


Theories Of Consciousness And A Life Worth Living, Liad Mudrik, Myrto Mylopoulos, Niccolo Negro, Aaron Schurger Sep 2023

Theories Of Consciousness And A Life Worth Living, Liad Mudrik, Myrto Mylopoulos, Niccolo Negro, Aaron Schurger

Psychology Faculty Articles and Research

What is it that makes a life valuable? A popular view is that life’s moral worth depends in some way on its relationship to consciousness or subjective experience. But a practical application of this view requires the ability to test for consciousness, which is currently lacking. Here, we examine how theories of consciousness (ToCs) can help do so, focusing especially on difficult cases where the answer is not clear (e.g. fetuses, nonhuman animals, unresponsive brain-injured patients, and advanced artificial systems). We consider five major ToCs and what predictions they offer: Integrated information theory, Higher-Order Thought Theory, Recurrent Processing Theory, Global …

Assessing Blood Oxygen Level–Dependent Signal Variability As A Biomarker Of Brain Injury In Sport-Related Concussion, Evan D. Anderson, Tanveer Talukdar, Grace Goodwin, Valentina Di Pietro, Kamal M. Yakoub, Christopher E. Zwilling, David Davies, Antonio Belli, Aron K. Barbey

Center for Brain, Biology, and Behavior: Faculty Publications

Mild traumatic brain injury is a complex neurological disorder of significant concern among athletes who play contact sports. Athletes who sustain sport-related concussion typically undergo physical examination and neurocognitive evaluation to determine injury severity and return-to-play status. However, traumatic disruption to neurometabolic processes can occur with minimal detectable anatomic pathology or neurocognitive alteration, increasing the risk that athletes may be cleared for return-to-play during a vulnerable period and receive a repetitive injury. This underscores the need for sensitive functional neuroimaging methods to detect altered cerebral physiology in concussed athletes. The present study compared the efficacy of Immediate Post-concussion Assessment and …


A Pilot Randomized Controlled Trial Evaluating Peer Recovery Coaches For Addiction Recovery Among Indigenous Americans, Nicholas Guenzel Aug 2023

A Pilot Randomized Controlled Trial Evaluating Peer Recovery Coaches For Addiction Recovery Among Indigenous Americans, Nicholas Guenzel

Theses & Dissertations

Addiction is a common and devastating problem among many Indigenous American (IA) groups around the United States. Too few IA health care providers are available to deliver care in a way that leverages IA values and traditions to support addiction recovery. Peer recovery coaches (PRCs) are individuals who have lived experience of addiction and have received specialized training in helping others in recovery. IA PRCs hold significant potential in helping to fill the gap of culturally-specific support in addiction. In this feasibility trial, we recruited a total of 120 adult (≥19 years) IAs with a substance use disorder through Facebook …

Identification Of Structural Brain Alterations In Adolescents With Depressive Symptomatology, J. Bashford‑Largo, R. James R. Blair, Karina S. Blair, Matthew Dobbertin, Ahria Dominguez, Melissa Hatch, Sahil Bajaj

Center for Brain, Biology, and Behavior: Faculty Publications

Introduction: Depressive symptoms can emerge as early as childhood and may lead to adverse situations in adulthood. Studies have examined structural brain alternations in individuals with depressive symptoms, but findings remain inconclusive. Furthermore, previous studies have focused on adults or used a categorical approach to assess depression. The current study looks to identify grey matter volumes (GMV) that predict depressive symptomatology across a clinically concerning sample of adolescents.

Methods: Structural MRI data were collected from 338 clinically concerning adolescents (mean age = 15.30 SD=2.07; mean IQ = 101.01 SD=12.43; 132 F). Depression symptoms were indexed via the Mood …


Predicting Suicide Attempt History: Self-Report And Objective Measures Of Pain, Boriana Lassiter Aug 2023

Predicting Suicide Attempt History: Self-Report And Objective Measures Of Pain, Boriana Lassiter

Graduate Theses and Dissertations (2019 - present)

The aim of this study was to replicate a factor analysis of the Painful and Provocative Events Scale (PPES), to test whether commonly used self-report measures associated with the Interpersonal Theory of (IPTS) would predict suicide attempt status and suicidal history, and to test whether physical pain sensitivity would differentiate suicide attempers, ideators, and those with no suicidal history (controls). Factor analysis of the PPES yielded a 5-factor solution consisting of Rare and Illegal Activities, Abuse Experience, Dangerous Sports, Medical Trauma, and Body Modification. Only Abuse Experience predicted suicide attempt status and overall suicidal history. Abuse Experience, the Psychache Scale, …

Affect Variability And Physical Health: The Moderating Role Of Mean Affect, Brooke N. Jenkins, Lydia Q. Ong, Hee Youn (Helen) Lee, Anthony D. Ong, Julia K. Boehm Jul 2023

Affect Variability And Physical Health: The Moderating Role Of Mean Affect, Brooke N. Jenkins, Lydia Q. Ong, Hee Youn (Helen) Lee, Anthony D. Ong, Julia K. Boehm

Psychology Faculty Articles and Research

Research has only begun to explore how affect variability relates to physical health and has typically not assessed long-term associations nor considered the moderating role of mean affect. Therefore, we used data from the Midlife in the United States Study waves 2 (N = 1512) and 3 (N = 1499) to test how affect variability predicted concurrent and long-term physical health while also testing the moderating role of mean affect. Results indicated that greater negative affect variability was associated concurrently with a greater number of chronic conditions (p = .03) and longitudinally with worse self-rated physical health (p …


Understanding The Effects Of Empathy And Masculine Gender Role Stress On The Relationship Between Gender And The Understanding Of Consent In Adolescents: A Moderated Mediation Framework, Kate Degenhardt Jun 2023

Understanding The Effects Of Empathy And Masculine Gender Role Stress On The Relationship Between Gender And The Understanding Of Consent In Adolescents: A Moderated Mediation Framework, Kate Degenhardt

Clinical Psychology Dissertations

This research examined the relationship between masculine gender role stress and empathy in youths ages 11-19 and their ability to understand the concept of consent. I examined a moderated mediation model where the effect of gender on the understanding of consent via masculine gender role stress was permitted to differ as a function of levels of empathy. The moderated mediation was evaluated in a stepwise fashion. A simple mediation examining the degree to which MGRS mediated the relation of gender on consent revealed all effects were significant, including the indirect effect (B = 0.561, SE = .292 95, CI 0.100, …


Tattoos And Trauma: Are Tattoos Healing For Trauma?, Krystal Bell Jun 2023

Tattoos And Trauma: Are Tattoos Healing For Trauma?, Krystal Bell

University Honors Theses

Prior research and literature reviews suggest that there is medicinal value in tattooing for the healing of trauma. However, tattooing is still a burgeoning topic in academic studies and still mostly taboo as a western societal practice, so there are gaps in qualitative and quantitative data that could further validate the healing benefits of tattoos for trauma. This literature review analyzed 30 peer reviewed articles that focus on "contemporary tattoo data," "indigenous traditions and practices," "tattoos and trauma," and other alternative healing such as "MDMA, psilocybin, EMDR" to establish a well-rounded investigation into tattoos as an alternative healing option. The …


Missed And Prior Diagnoses In Children Later Diagnosed With Autism, Maire Diemer Jun 2023

Missed And Prior Diagnoses In Children Later Diagnosed With Autism, Maire Diemer

Dissertations

Awareness of autism is rising, yet social determinants of health continue to impact rates, ages of diagnosis, and diagnostic load. Different psychiatric labels carry stigmas; unequal rates of diagnoses may indicate biases in the healthcare system. This study investigates six prior diagnoses (ADHD, disorders of conduct, adjustment, anxiety, mood, and intellectual disability) assigned to children who are later diagnosed with autism. The study investigates how race, sex, and geographic factors were associated with age of diagnosis and diagnostic load. This study utilized a sample of 13,850 children aged 2-10 who were diagnosed with autism on Missouri Medicaid between 2015 and …

Effects Of Daylight On College Students’ Physical And Mental Well-Being, Sathya Thenappan Jun 2023

Effects Of Daylight On College Students’ Physical And Mental Well-Being, Sathya Thenappan

Quantitative Social Science Undergraduate Senior Theses

While existing literature predominantly deals with the impact of daylight on adults in general and more specifically at the workplace, less is known about its impact on the college student demographic and daylight exposure levels at college residences. Given its considerable impact on both the physical and mental well-being of individuals, daylight has been used in the treatment of an assortment of diseases from seasonal affective disorder to depression. With college students constituting the majority of today’s people who suffer from mental health issues in society, uncovering the link between daylight exposure and its impact on the physical and mental …


Interview Of Pilots’ Inflight Loss Of Control Experiences, Neelakshi Majumdar, Karen Marais May 2023

Interview Of Pilots’ Inflight Loss Of Control Experiences, Neelakshi Majumdar, Karen Marais

International Symposium on Aviation Psychology - 2023

Inflight loss of control (LOC-I) continues to be a significant cause of General Aviation fixed-wing aircraft accidents. Nearly 20% of fixed-wing aircraft accidents in the last two decades involved LOC-I, and approximately 45% of LOC-I accidents are fatal. Previous studies suggest that the leading factors in aviation accidents are human factors-related. One approach to better understand the causes of LOC-I accidents is to analyze accidents using sources such as the National Transportation Safety Board (NTSB) database. However, the NTSB General Aviation accident reports include limited detail on human factors, specifically pilot actions and conditions. We interviewed pilots about their LOC-I …


A Multi-Method Approach To Work Design For Crew In Future Remotely Piloted Aircraft Operations, Kayler Marshall, Penelope Sanderson, Andrew Neal May 2023

A Multi-Method Approach To Work Design For Crew In Future Remotely Piloted Aircraft Operations, Kayler Marshall, Penelope Sanderson, Andrew Neal

International Symposium on Aviation Psychology - 2023

Globally, most safety regulators only allow crew to operate one remotely piloted aircraft (RPA) at a time due to workload concerns. More sophisticated automation is anticipated to alleviate operator workload, allowing crew to simultaneously operate more than one RPA. However, how work should be distributed amongst crew is still unknown. We employ a complementary set of methods for work design in a future system of RPA operation: Cognitive Work Analysis, computational modelling, and human-in-the-loop experiments. In this paper we describe each method, outlining the unique insights gained and how these are applied in the evaluation of work in a future …


Exploring Informal Learning Structures In Airline Operations, Barth Baron Jr., Dorrit Billman, Randall J. Mumaw May 2023

Exploring Informal Learning Structures In Airline Operations, Barth Baron Jr., Dorrit Billman, Randall J. Mumaw

International Symposium on Aviation Psychology - 2023

Airline pilot training is extensive, highly structured, and driven by aircraft and airspace system operating requirements, yet pilots describe a tradition of between-pilot knowledge transfer and self-directed learning. While industry and regulators focus on “formal learning” systems, pilots report relying on this “informal learning” to build operational expertise, suggesting gaps in how successfully formal learning prepares pilots to handle operational complexities. The community that researches learning has extensively studied informal learning, including in a workplace setting, and its characteristics align with how pilots report increasing their skills and knowledge informally. However, no research into informal learning practices among airline pilots …


Resilient Strategies In Commercial Aviation, Michael Stewart, Bryan Matthews May 2023

Resilient Strategies In Commercial Aviation, Michael Stewart, Bryan Matthews

International Symposium on Aviation Psychology - 2023

When we fly and nothing scary happens, is the system’s design affording this success? Not always — sometimes humans are the cause of success. This resilient performance is often overlooked. We explore two types of resilient performance strategies: countermeasures and modifications. countermeasures are behaviors triggered by variables anticipated to be challenging or problematic (i.e., pressures). To capture this, we look at examples of how a problem was avoided. For example, a country road may have a hairpin turn where accidents more frequently occur. With this pressure identified, we look at successful drivers for insights. Modifications are changes that are created …


Extracting Lessons Of Resilience Using Machine Mining Of The Asrs Database, Immanuel Barshi, Bryan Matthews, Jolene Feldman May 2023

Extracting Lessons Of Resilience Using Machine Mining Of The Asrs Database, Immanuel Barshi, Bryan Matthews, Jolene Feldman

International Symposium on Aviation Psychology - 2023

NASA’s Aviation Safety Reporting System (ASRS) database is the world's largest repository of voluntary, confidential safety information provided by aviation's frontline personnel. The database contains close to 2 million narratives, many of which describe everyday situations in which people saved the day. In these situations, people’s resilient behavior solved a problem, dealt with a malfunction, and maintained a safe operation despite a serious perturbation. To be able to extract lessons of such resilience from this large database, the use of machine learning algorithms is being explored. In this report, we describe a comparison between two such algorithms: BERT and Word2Vec. …


The Viability Of See-And-Avoid For Urban Air Mobility Operations, Richard Mogford, Walter Johnson May 2023

The Viability Of See-And-Avoid For Urban Air Mobility Operations, Richard Mogford, Walter Johnson

International Symposium on Aviation Psychology - 2023

Urban Air Mobility (UAM) is an emerging aviation concept that could supplement today’s ground and air transportation systems. For UAM, it is generally assumed that the private sector will manage separation and not rely on the U.S. Federal Aviation Administration air traffic control system. To date, discussions of initial operations focus on using the visual abilities of the pilot to see-and-avoid (SAA) other aircraft. Decades of research on SAA has demonstrated that it is inadequate for reliable detection of aircraft that might pose a collision risk. The literature on multi-object tracking is also reviewed for findings on how well humans …


Nasa Human Factors Red Light/Green Light Analysis: Overview And Spacshiptwo Rl/Gl Case Study, Tracy Dillinger, Isabel Hernandez May 2023

Nasa Human Factors Red Light/Green Light Analysis: Overview And Spacshiptwo Rl/Gl Case Study, Tracy Dillinger, Isabel Hernandez

International Symposium on Aviation Psychology - 2023

Historically, learning from accidents and incidents involves identifying errors of commission or omission and “things that go wrong” and how to reduce their recurrence. While well-intentioned, infrequent failures receive more attention than everyday successes. Human Factors analysis need not limit itself to learning from failures. Learning from “what goes right” involves identifying resilience factors associated with behaviors and processes that strengthen the system and reduce risk. This article provides an overview of how the National Aeronautics and Space Administration (NASA) Human Factors Task Force (HFTF) constructed the NASAHFACS model and the Red Light/Green Light approach. Using SpaceShipTwo as a case …


Concept Of A Cognitive Agent Supporting Collaboration In Human Teams, Wolfgang Sachsenhauser, Axel Schulte May 2023

Concept Of A Cognitive Agent Supporting Collaboration In Human Teams, Wolfgang Sachsenhauser, Axel Schulte

International Symposium on Aviation Psychology - 2023

This contribution aims at the support of human teamwork between crew members of next generation combat aircraft by means of a distributed and adaptive assistant system. In future combined air operations several aircraft, manned and unmanned, operate together to achieve a common mission objective. That requires a high degree of coordination amongst the pilots, each of them being highly charged with e.g., managing unmanned vehicles from their cockpits. Our approach is to develop a distributed assistant system that observes each pilot in their cockpits. By use of a task model, it shall create and update a shared representation of the …
