Exploring The Effect Of Counterstereotype And Perspective Taking In Reducing Bias And Promoting Empathy In Police, Sydney C. Timmer-Murillo, Keara Kangas, Nakia Gordon

Psychology Faculty Research and Publications

Racism in policing continues to be a serious issue in the United States (U.S.). While most efforts to reduce racism, focus on changing implicit (i.e., nonconscious) racial biases, other factors may also influence behavior. Intergroup emotion theory posits that emotions, especially empathy, may play a powerful role in changing behavior. In this study, using community-based participatory research design we created and tested a virtual reality (VR) experience designed to reduce implicit racial bias through perspective taking and counter-stereotypical information. Fifty-six police officers from a large city took part in the study. They completed questionnaires and an implicit association task (IAT) …

Childhood Maltreatment And Deviations From Normative Brain Structure: A Mega-Analysis Of 3711 Individuals From The Enigma Major Depressive Disorder And Enigma Posttraumatic Stress Disorder Working Groups, Jacklynn M. Fitzgerald

Psychology Faculty Research and Publications

Background. Childhood maltreatment (CM), encompassing abuse and neglect, is highly prevalent and associated with elevated risk for major depressive disorder (MDD), posttraumatic stress disorder (PTSD), and other related conditions. However, the extent to which neuroanatomical alterations in MDD and PTSD are attributable to CM is uncertain.

Methods. Here, we analyzed CM and whole-brain magnetic resonance imaging (MRI) data from 3711 participants in the ENIGMA (Enhancing Neuro Imaging Genetics through Meta Analysis) MDD and PTSD Working Groups (25 sites; mean age = 33.3 ± 13.0 years; 59.9% female). Normative modeling estimated deviation z scores for 14 subcortical volume, 68 cortical thickness …

Image-Based Meta- And Mega-Analysis (Ibmma): A Unified Framework For Large-Scale, Multi-Site, Neuroimaging Data Analysis, Jacklynn M. Fitzgerald

Psychology Faculty Research and Publications

The increasing scale and complexity of neuroimaging datasets aggregated from multiple study sites present substantial analytic challenges, as existing statistical analysis tools struggle to handle missing voxel-data, suffer from limited computational speed and inefficient memory allocation, and are restricted in the types of statistical designs they are able to model. We introduce Image-Based Meta- & Mega-Analysis (IBMMA), a novel software package implemented in R and Python that provides a unified framework for analyzing diverse neuroimaging features, efficiently handles large-scale datasets through parallel processing, offers flexible statistical modeling options, and properly manages missing voxel-data commonly encountered in multi-site studies. IBMMA successfully …

The Functional Connectome Mediates Associations Between Fitness And Cognition Across The Adult Lifespan, Juniad Merchant, Jeremy J. Purcell, Daniel D. Callow, Junyeon Won, Yash Kommula, Samuel Rosenberg, Yi Wei, John L. Woodard, Kristy A. Nielson, Stephen M. Rao, Sally Durgerian, Shuo Chen, J. Carson Smith

Psychology Faculty Research and Publications

Cardiorespiratory fitness (CRF) is increasingly recognized as essential for improving neural and cognitive function, especially in older age. Here, we examined a cross-sectional sample of the Human Connectome Project (HCP) Aging dataset (ages 36–100; N = 378) to test the hypothesis that functional connectivity profiles that are related to CRF are also associated with episodic memory and executive function across middle age and older adults. To test these hypotheses, we first used connectome-based predictive modeling (CPM) to identify functional connections (FCs) that were separately predictive of CRF (2 Minute Walk Test), episodic memory (Rey Auditory Verbal Learning Test), and executive …

Espil, Jordan T. Stiede, Jennifer S. Schild, Shannon M. Bennett, Matthew W. Specht, John T. Walkup, Douglas W. Woods, John Piacentini, Emily J. Ricketts

Psychology Faculty Research and Publications

Background: Sleep disturbance is common in individuals with Tourette’s disorder (TD). Tic symptoms, medication, functional impairment, and psychiatric comorbidity frequently contribute to sleep disturbance in children and adults with TD. However, long-term predictors of sleep disturbance in TD are not known. This study examined longitudinal and cross-sectional predictors of sleep disturbance in a treatment follow-up sample with TD.

Methods: Eighty subjects who completed a 10-week randomized controlled trial of behavior therapy for tics in childhood (M_age = 11.47, SD = 2.42 years) participate in follow-up evaluation on average, 11.17 (SD = 1.25) years after post-treatment assessment ( …

Volumetric Differences Of Thalamic Nuclei Are Associated With Posttrauma Psychopathology, Jacklynn M. Fitzgerald

Psychology Faculty Research and Publications

Background

Previous investigations of whole thalamus and thalamic nuclei volumes in posttrauma psychopathology have been sparse and limited in scope and have yielded inconsistent results. To address this, volumetric estimates of whole thalamus and thalamic nuclei were obtained from structural brain magnetic resonance imaging scans from 2058 participants across 20 worldwide sites in the ENIGMA (Enhancing Neuro Imaging Genetics through Meta Analysis) Posttraumatic Stress Disorder (PTSD) working group.

Methods

Thalamic volumes were compared in trauma-exposed participants with PTSD (n = 238), major depressive disorder (MDD) (n = 184), and comorbid PTSD+MDD (n = 618) and in trauma-exposed …

Ptsd Symptoms Moderate Predictors Of Psychophysiological Arousal During Fear Inhibition: Evidence From A Fear, Reward, And Neutral Discrimination Task, Jacklynn M. Fitzgerald, E. Kate Webb, Kaley Davis, Meghan Bennett, Tristan Benjamin, Boiana Pegau, Susan Sangha

Psychology Faculty Research and Publications

The ability to distinguish between threatening, rewarding, and neutral cues is adaptative and crucial for survival. However, individuals with posttraumatic stress disorder (PTSD) often show poor knowledge of cue contingencies and heightened fear responses even in the presence of cues that signify safety, potentially due to atypical perceptions of neutral cues. We investigated whether perceiving neutral cues as more rewarding or threatening influences conditioned inhibition of fear and whether PTSD symptoms moderate this relationship. Trauma-exposed adults (N = 84; 64 % female; 76 % non-Hispanic white) completed a Fear, Reward, and Neutral Discrimination (FRND) Task involving geometric shapes paired with …

Experiences Of Discrimination During Pregnancy Predict Altered Neonatal Hair Cortisol At Birth, Kimberly D'Anna-Hernandez, Lillybelle K. Deer, Özlü Aran, Kenia M. Rivera, Melissa Nevarez-Brewster, Jenalee R. Doom, Benjamin L. Hankin, M. Camille Hoffman, Elysia Poggi Davis

Psychology Faculty Research and Publications

Objective

Prenatal glucocorticoids (e.g., cortisol) are a widely proposed prenatal programming mechanism, yet few studies directly measure fetal cortisol. Neonatal hair provides a non-invasive method to assess fetal cortisol. The current studies test the association between maternal exposure to discrimination and fetal cortisol, as measured in neonatal hair, in two cohorts.

Methods

Study 1: Pregnant individuals (N = 65) and their neonates (61.8 % female) participated in study 1 between 2017 and 2021.

Data-Driven Approach To Dynamic Resting State Functional Connectivity In Post-Traumatic Stress Disorder: An Enigma-Pgc Ptsd Study, Jacklynn M. Fitzgerald

Psychology Faculty Research and Publications

Using functional magnetic resonance imaging (fMRI), symptoms of posttraumatic stress disorder (PTSD) have been associated with aberrations in brain networks in the absence of a given cognitive demand or task, called resting-state networks. Prior work has focused on disruption in the static functional connectivity (FC) among specific regions constrained by a priori hypotheses. However, dynamic FC, an approach that examines brain network characteristics over time, may provide a more sensitive measure to understand the network properties underlying dysfunction in PTSD. Further, using a data-driven analytic approach may reveal the contribution of other larger network disturbances beyond those revealed by hypothesis-driven …

Understanding Intergenerational Trauma Among Arab, Middle Eastern, And North African (Arab/Mena) Americans, Rawan H. Atari-Khan, Nuha Alshabani, S. Dolma Rabgay, Farida Refaat Elhedk, Ava Clifford, Sofia Gomariz, Warda Sahib

Psychology Faculty Research and Publications

Arab, Middle Eastern, and North African Americans experience various forms of racial–ethnic trauma in the United States, including historical and intergenerational trauma (IGT). The population has been migrating to the United States since the 1800s, and the number of migrants has risen in recent decades due to war, persecution, and family reunification. As a result, the children of these migrants may be exposed to IGT, with research suggesting that descendants of individuals who have experienced trauma are more susceptible to poor mental health outcomes. Using semistructured interviews, alongside the art of storytelling and empowerment through critical consciousness, this study investigated …

Understanding Parents’ Beliefs About The Etiology Of Youth Mental Health Problems: Differences Across Race/Ethnicity, Madeline Buchanan, Lindsay E. Holly

Psychology Faculty Research and Publications

Parents’ etiological explanations for youth mental health problems are relatively understudied; most studies focus on adult beliefs about the causes of mental disorders experienced by adults. This is concerning given research demonstrating that parents’ causal beliefs may influence several aspects of youth mental health service utilization including whether parents seek help for their youth and how they engage in treatment. The current study used a novel methodology to examine causal beliefs about youth mental health problems among a diverse group of parents (N = 417; 36.9% non-Hispanic White; 33.3% Black/African American; 29.8% Hispanic/Latino) who completed a series of questionnaires …

“Much Like Skydiving, I Would Really Rather Avoid It If I Can”: Asexual And Allosexual Adults’ Motives For Not Having Sexual Experiences, Alyssa N. Clark, Tracy L. Walters, Veronica Hanna-Walker

Psychology Faculty Research and Publications

Engaging in sex is a common practice, however, some adults may choose to not have sexual experiences for normative reasons. Asexual adults, in particular, may hold negative attitudes about sex and are less likely than allosexual adults to engage in sex. Less is known about whether adults’ motives to not have any sexual experiences differ based on sexual orientation. We use qualitative to explore asexual and allosexual adults’ intrinsic and extrinsic motives for not having sexual experiences. From a larger study, 129 adults with no sexual experiences (52.7% allosexual, Mage  = 22.0, 47.3% asexual, Mage  = 25.4; 61.2% …

Tomas, Sydney Timmer-Murillo, Terri A. Deroon-Cassini, Christine Larson, Lucas Torres, Amber Brandolino, Timothy J. Geier, Hason Khan, Andrew T. Schramm

Psychology Faculty Research and Publications

The COVID-19 pandemic significantly impacted the psychological well-being of the general population. However, there are limited studies that examine its mental health effects on patients who have experienced traumatic injuries and tracked their recovery over time. This study aimed to: (1) compare the rates and severity of post-traumatic stress disorder (PTSD) and depression between patients who sustained traumatic injuries before the COVID-19 pandemic (pre-pandemic) and those injured during the pandemic (peri-pandemic); and (2) assess whether the degree of pandemic-related stress (e.g., worry about infection, social isolation, loss of home/job) predicted the severity of PTSD or depression symptoms. Participants (N …

Discrimination And Adverse Birth Outcomes Among Latina Women: The Protective Role Of Social Support., Sabrina R. Liu, Kimberly D'Anna-Hernandez, Curt A. Sandman, Elysia Poggi Davis, Laura M. Glynn

Psychology Faculty Research and Publications

Interpersonal discrimination has been associated with adverse birth outcomes among Black populations, but few studies have examined the impact of discrimination among Latinx/Hispanic populations in the United States, especially in conjunction with resources that could be protective. The present study examined (a) if exposure to discrimination is associated with adverse birth outcomes for Latina/Hispanic women and (b) if prenatal social support buffers these links. Method: In two independent prospective studies of Latina/Hispanic women in Southern California (N = 84 and N = 102), the relation between maternal experience of discrimination and birth outcomes (length of gestation and birth weight) …

Commentary: Caring About Caregivers And The Importance Of Refining Methodology In Caregiver-Focused Studies, Johanna Michlig, Astrida S. Kaugars

Psychology Faculty Research and Publications

Significant progress has been made in advancing caregiver wellbeing research and clinical application in the last decade (Salley et al., 2024). This commentary on the work of Badovinac et al. (2024) will highlight the importance of more comprehensively examining context in caregiver responses. Caregivers live within the push and pull between social and family demands, and it is vital to expand our view to gain a more comprehensive understanding of their experience. Consequently, the methodology of future studies with caregivers must reflect those demands and complexities.

An Evaluation Of Durability During And Following Delay-And-Denial Tolerance Teaching, Kendall M. Kastner, Stephanie Hood, Daniel R. Mitteer

Psychology Faculty Research and Publications

Across five treatment applications, we evaluated two forms of treatment relapse (renewal, resurgence) with a version of functional communication training known as delay-and-denial tolerance teaching. Renewal of challenging behavior following a context change occurred for most treatments, but challenging behavior did not increase to clinically significant levels in most cases. Resurgence of challenging behavior following decrements in alternative reinforcement occurred only in two of five extinction tests when communication responses were placed on extinction. Omitting alternative activities during extinction tests led to an appreciable increase in resurgence for one of the three participants who did not display resurgence initially. Despite …

A Comparison Of Training Procedures On The Emergence Of Intraverbal-Tacts, Mary Halbur, Tiffany Kodak, Jessi Reidy

Psychology Faculty Research and Publications

Vocal exchanges are often comprised of responses under multiple sources of stimulus control. For example, a picture may contain multiple components, and an instructor may ask a learner to respond differentially to questions about the picture (e.g., “who,” “what,” “where,” “color,” “number,” “shape”). The format of teaching may affect the development of verbal behavior under multiple sources of stimulus control. Therefore, the present investigation compared teaching stimuli in isolation to teaching with compound stimuli on the emergence of verbal behavior to evaluate methods that assist with correctly answering questions about compound stimuli. This study used a translational model with undergraduate …

Neural Processes Of Emotional Conflict Detection And Prediction Of Posttraumatic Stress Disorder Symptom Clusters In Traumatic Injury Survivors, Kaley E. Davis, Carissa W. Tomas, Kate E. Webb, Ashley A. Huggins, Terri A. Deroon-Cassini, Christine L. Larson, Jacklynn M. Fitzgerald

Psychology Faculty Research and Publications

Objective: Given the prevalence and significant burden of posttraumatic stress disorder (PTSD), identifying early predictors of symptom development following trauma is critical. PTSD is a heterogeneous disorder comprised of distinct symptom clusters-reexperiencing, avoidance, negative mood, and hyperarousal-that contribute to the broad range of possible symptom profiles. Affective and attentional regulation processes, such as emotional conflict detection, are impaired in individuals with PTSD; however, the neural mechanisms underlying these alterations and their predictive utility for the development of PTSD symptoms remain unclear.

Method: Traumatic injury survivors (N = 49) without traumatic brain injury were recruited from the emergency department of …

Psychology Faculty Research and Publications

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 …

Functional And Effective Eeg Connectivity Patterns In Alzheimer’S Disease And Mild Cognitive Impairment: A Systematic Review, Elizabeth Paitel, Christian B. Otteman, Mary C. Polking, Henry J. Licht, Kristy A. Nielson

Psychology Faculty Research and Publications

Background:

Alzheimer’s disease (AD) might be best conceptualized as a disconnection syndrome, such that symptoms may be largely attributable to disrupted communication between brain regions, rather than to deterioration within discrete systems. EEG is uniquely capable of directly and non-invasively measuring neural activity with precise temporal resolution; connectivity quantifies the relationships between such signals in different brain regions. EEG research on connectivity in AD and mild cognitive impairment (MCI), often considered a prodromal phase of AD, has produced mixed results and has yet to be synthesized for comprehensive review. Thus, we performed a systematic review of EEG connectivity in MCI …

The main findings, in the …

Professional Skills For Behavior Analysts: A Survey On The Proficiency And Importance Of Hard And Soft Skills, Landon S. Cowan, Tiffany Kodak

Psychology Faculty Research and Publications

Individuals seeking certification as board certified behavior analysts (BCBAs) require training in both hard and professional (soft) skills. Trainees seeking certification complete coursework, supervised fieldwork experience, and a BCBA exam that assesses mastery of hard skills. However, training and mastery of soft skills is not as defined. BCBAs are also expected to maintain these skills throughout their career. Previous research has shown that soft skills are viewed as important by clients and their caregivers but are not consistently demonstrated from those providing services. Research also suggests that BCBA trainees may not consistently receive training on soft skills. The current study …

Anxiety And Body-Focused Repetitive Behaviors: A Systematic Review And Meta-Analysis Of Comorbidity Rates And Symptom Associations, Kathryn E. Barber, Isabella F. Cram, Elyse C. Smith, Leila K. Capel, Ivar Snorrason, Douglas W. Woods

Psychology Faculty Research and Publications

Body-focused repetitive behavior (BFRB) disorders, including hair pulling disorder (trichotillomania [TTM]) and skin picking disorder (SPD), frequently co-occur with anxiety disorders, but reported comorbidity rates vary widely. Additionally, research on the relationship between anxiety and BFRB symptoms has yielded inconsistent findings. This meta-analysis and systematic review examined (1) the prevalence of comorbid anxiety disorders in individuals with BFRB disorders and (2) correlations between anxiety and BFRB symptom measures. The study protocol was pre-registered on PROSPERO. A systematic search of PsycInfo, PubMed, and Web of Science identified 119 studies (N=15,902) reporting anxiety prevalence rates in BFRB disorders and/or correlations between anxiety …

Editorial: To Know Or Not To Know: Causes And Evolution Of Lack Of Awareness Of Cognitive Decline In Neurodegenerative Diseases, Volume Ii, Federica Cacciamani, Kristy A. Nielson, Bernard J. Hanseeuw, Geoffroy P. Gagliardi, Patrizia Vannini

Psychology Faculty Research and Publications

Anosognosia, or the lack of awareness of cognitive, behavioral, or functional deficits, represents a critical challenge in the clinical management of neurodegenerative diseases such as Alzheimer's disease (AD) and frontotemporal dementia. This condition not only impacts patients, caregivers, and healthcare systems (D'Souza et al., 2011; Turró-Garriga et al., 2013) but also raises important questions about its underlying mechanisms and evolution (Hanseeuw et al., 2020; Starkstein, 2014; Vannini et al., 2017). Despite its critical importance, significant gaps remain in our understanding of cognitive self-awareness in neurodegenerative diseases. Building on the momentum of the first edition of To Know or Not to …

Alexithymia: Toward An Experimental, Processual Affective Science With Effective Interventions, Olivier Luminet, Kristy A. Nielson

Psychology Faculty Research and Publications

Alexithymia is a multi-dimensional personality trait involving difficulty identifying feelings, difficulty describing feelings, and an externally oriented thinking style. Poor fantasy life is debated as another facet. For over 50 years, the alexithymia literature has examined how alexithymia-related disturbances in perceiving and expressing feelings contribute to mental and physical disorders. We review the current understanding of alexithymia—including its definition, etiology, measurement, and vulnerabilities for both mental and physical illness—and its treatment. We emphasize the importance of further experimental and processual affective science research that (a) emphasizes facet-level analysis toward an understanding of the nuanced bases of alexithymia effects on neural, …
