Subjective Well-Being And Bilateral Anterior Insula Functional Connectivity After Exercise Intervention In Older Adults With Mild Cognitive Impairment, Junyeon Won, Kristy A. Nielson, J. Smith Carson May 2022

Subjective Well-Being And Bilateral Anterior Insula Functional Connectivity After Exercise Intervention In Older Adults With Mild Cognitive Impairment, Junyeon Won, Kristy A. Nielson, J. Smith Carson

Psychology Faculty Research and Publications

While it is well known that exercise training is associated with improvement in subjective well-being among older adults, it is unclear if individuals with cognitive impairment experience the same effects elicited by exercise on subjective well-being. We further explored whether the bilateral anterior insula network may be an underlying neural mechanism for the exercise training-related improvements in subjective well-being. We investigated the effects of exercise training on subjective well-being in older adults (78.4 ± 7.1 years) with mild cognitive impairment (MCI; n = 14) and a cognitively normal (CN; n = 14) control group. We specifically assessed the relationship between …


Replication Of A Skills Assessment For Auditory–Visual Conditional Discrimination Training, Tiffany Kodak, Samantha Bergmann, Maria Clara Cordeiro, Meredity Bamond, Robert W. Isenhower, Kate E. Fiske Apr 2022

Replication Of A Skills Assessment For Auditory–Visual Conditional Discrimination Training, Tiffany Kodak, Samantha Bergmann, Maria Clara Cordeiro, Meredity Bamond, Robert W. Isenhower, Kate E. Fiske

Psychology Faculty Research and Publications

Auditory–visual conditional discrimination training (e.g., receptive identification training, listener responses; AVCD) is ubiquitous in early intervention and special education programs. Nevertheless, some learners with Autism Spectrum Disorder (ASD) do not appear to benefit from this training despite use of empirically validated treatments. To prevent exposure to extended training that does not lead to learning, a skills assessment that measures skills related to AVCD training will be useful for educators and practitioners. The current study replicated the skills assessment developed and evaluated by Kodak et al. (2015) with 8 participants with ASD who received behavior analytic intervention that included at least …

Weis, Ashley A. Huggins, Kenneth P. Bennett, Tara A. Miskovich, Jessica L. Krukowski, Terri A Deroon-Cassini, Christine L. Larson Feb 2022

Hippocampal Resting-State Functional Connectivity Forecasts Individual Posttraumatic Stress Disorder Symptoms: A Data-Driven Approach, Jacklynn M. Fitzgerald, Elisabeth Kate Webb, Carissa N. Weis, Ashley A. Huggins, Kenneth P. Bennett, Tara A. Miskovich, Jessica L. Krukowski, Terri A Deroon-Cassini, Christine L. Larson

Psychology Faculty Research and Publications

Background: Posttraumatic Stress Disorder (PTSD) is a debilitating disorder and there is no current accurate prediction of who develops it after trauma. Neurobiologically, individuals with chronic PTSD exhibit aberrant resting-state functional connectivity (rsFC) between the hippocampus and other brain regions (e.g., amygdala, prefrontal cortex, posterior cingulate), and these aberrations correlate with severity of illness. Prior small-scale research (n < 25) has also shown that hippocampal-rsFC measured acutely after trauma is predictive of future severity using an ROI-based approach. While a promising biomarker, to-date no study has employed a data-driven approach to test whole-brain hippocampal-FC patterns in forecasting the development of PTSD symptoms.

Methods: Ninety-eight adults at risk of PTSD were recruited from the emergency department following traumatic injury and completed resting functional magnetic resonance imaging (rsfMRI; 8min) within 1-month; 6-months later they completed the Clinician-Administered PTSD Scale (CAPS-5) for assessment of PTSD symptom …

Importance For Black US residents, experiences of racial discrimination are still pervasive and frequent. Recent empirical work has amplified the lived experiences and narratives of Black people and further documented the detrimental effects of racial discrimination on both mental and physical health; however, there is still a need for further research to uncover the mechanisms connecting experiences of racial discrimination with adverse health outcomes.

Objective To examine neurobiological mechanisms that may offer novel insight into the association of racial discrimination with adverse health outcomes.

Design, Setting, and Participants This cross-sectional study included 102 Black adults who had recently experienced a …

Trajectories Of Relational Turbulence And Affectionate Communication Across The Post-Deployment Transition, Leanne K. Knobloch, Lynne M. Knobloch-Fedders, Jeremy B. Yorgason, Erin C. Wehrman, J. Kale Monk

Psychology Faculty Research and Publications

Affectionate communication may play a key role in how military couples navigate the transition from deployment to reintegration. Informed by relational turbulence theory, this study considered how the trajectory of relational turbulence experienced by military couples over time predicted their verbal and nonverbal expressions of affection. Online self-report data were gathered from 268 U.S. military couples across eight months beginning at homecoming. Relational turbulence increased over time and affectionate communication decreased over time. Also as predicted, the trajectory of increasing relational turbulence corresponded with greater declines in verbal and nonverbal expressions of affection. These results advance relational turbulence theory, illuminate …


A Cluster Analytic Approach To Examining The Role Of Cortisol In The Development Of Post-Traumatic Stress And Dysphoria In Adult Traumatic Injury Survivors, Devi Jayan, Terri A Deroon-Cassini, Garrett Sauber, Cecilia J. Hillard, Jacklynn M. Fitzgerald Jan 2022

A Cluster Analytic Approach To Examining The Role Of Cortisol In The Development Of Post-Traumatic Stress And Dysphoria In Adult Traumatic Injury Survivors, Devi Jayan, Terri A Deroon-Cassini, Garrett Sauber, Cecilia J. Hillard, Jacklynn M. Fitzgerald

Psychology Faculty Research and Publications

Identification of specific risk factors for posttraumatic stress disorder (PTSD) versus depression after trauma has been challenging, in part due to the high comorbidity of these disorders. As exposure to trauma triggers activation of the hypothalamic-pituitary-adrenal (HPA)-axis, examining atypical stress responses via HPA-axis hormones, namely cortisol, may help in the delineation of these disorders. Indeed, extant research demonstrates that, following stress, individuals with chronic PTSD exhibit hypocortisolism (e.g., lower cortisol response than controls), while those with chronic depression exhibit hypercortisolism (e.g., higher response than controls). Less is known about the role of cortisol and these seemingly disparate profiles immediately following …

Background

Posttraumatic stress disorder (PTSD) is associated with markers of accelerated aging. Estimates of brain age, compared to chronological age, may clarify the effects of PTSD on the brain and may inform treatment approaches targeting the neurobiology of aging in the context of PTSD.

Method

Adult subjects (N = 2229; 56.2% male) aged 18–69 years (mean = 35.6, SD = 11.0) from 21 ENIGMA-PGC PTSD sites underwent T1-weighted brain structural magnetic resonance imaging, and PTSD assessment (PTSD+, n = 884). Previously trained voxel-wise (brainageR) and region-of-interest (BARACUS and PHOTON) machine learning pipelines were compared in a subset of control …

Associations Between Religiosity And Perinatal Anxiety Symptoms Among Women Of Mexican Descent, Kayla M. Osman, Sandraluz Lara-Cinisomo, Kimberly D'Anna-Hernandez

Psychology Faculty Research and Publications

Background

Over half of pregnant women experience anxiety symptoms, however perinatal mental health disparities exist. Women of Mexican descent exhibit higher levels of anxiety symptoms which may be linked to sociocultural stressors. However, little is known about culturally relevant factors that may protect against anxiety in this fast-growing population, such as religiosity, an important facet of Mexican culture.

Methods

Pregnant women of Mexican descent (n = 197) were recruited from a local community clinic and followed into the postpartum period. Women completed surveys assessing religiosity, acculturation, acculturative stress, and anxiety symptoms.

Results

Higher levels of religiosity were associated …

Nearly 14 percent of Americans live in a socioeconomically disadvantaged neighborhood. Lower individual socioeconomic position (iSEP) has been linked to increased exposure to trauma and stress, as well as to alterations in brain structure and function; however, the neural effects of neighborhood SEP (nSEP) factors, such as neighborhood disadvantage, are unclear. Using a multi-modal approach with participants who recently experienced a traumatic injury (N = 185), we investigated the impact of neighborhood disadvantage, acute post-traumatic stress symptoms, and iSEP on brain structure and functional connectivity at rest. After controlling for iSEP, demographic variables, and acute PTSD symptoms, nSEP was …


Teachers’ Impact On Psychosocial Treatment For Latinx Youth With Adhd, Margaret Grace, Theresa Lauer Kapke, Alyson C. Gerdes Oct 2021

Teachers’ Impact On Psychosocial Treatment For Latinx Youth With Adhd, Margaret Grace, Theresa Lauer Kapke, Alyson C. Gerdes

Psychology Faculty Research and Publications

This study examined the impact of teacher engagement in a psychosocial treatment for Latinx youth with attention-deficit/hyperactivity disorder (ADHD). Results revealed that teachers were equally engaged in treatment regardless of the source of the referral to treatment, indicating that teachers were motivated to work with students and families. Additionally, results indicated that referral source and teacher engagement in treatment were related to treatment outcomes. These findings indicate that higher-quality teacher intervention implementation is related to enhanced child and parent treatment outcomes in a Latinx sample. Results additionally revealed significant relationships among parental acculturation and treatment outcomes. Clinical implications are discussed.


Racial Discrimination Is Associated With Acute Posttraumatic Stress Symptoms And Predicts Future Posttraumatic Stress Disorder Symptom Severity In Trauma-Exposed Black Adults In The United States, Claire M. Bird, E. Kate Webb, Andrew T. Schramm, Lucas Torres, Christine L. Larson, Terri A. Deroon-Cassini Oct 2021

Racial Discrimination Is Associated With Acute Posttraumatic Stress Symptoms And Predicts Future Posttraumatic Stress Disorder Symptom Severity In Trauma-Exposed Black Adults In The United States, Claire M. Bird, E. Kate Webb, Andrew T. Schramm, Lucas Torres, Christine L. Larson, Terri A. Deroon-Cassini

Psychology Faculty Research and Publications

In the United States, Black residents exposed to a traumatic event are at an increased risk of developing posttraumatic stress disorder (PTSD) and experiencing more severe symptoms compared to their non‐Hispanic White counterparts. Although previous work has suggested a link between racial discrimination and PTSD symptoms, no studies have assessed this association in a sample of traumatic injury survivors. The current study investigated whether (a) past racial discrimination was associated with acute posttraumatic stress symptoms (PTSS) and (b) discrimination prospectively contributed to the prediction of future PTSD symptoms. African American and/or Black patients (N = 113) were recruited from an …


Acute White Matter Integrity Post-Trauma And Prospective Posttraumatic Stress Disorder Symptoms, Carissa N. Weis, Ashley A. Huggins, Tara A. Miskovich, Jacklynn M. Fitzgerald, Kenneth P. Bennett, Jessica L. Krukowski, E. Kate Webb, Terri A Deroon-Cassini, Christine L. Larson Sep 2021

Acute White Matter Integrity Post-Trauma And Prospective Posttraumatic Stress Disorder Symptoms, Carissa N. Weis, Ashley A. Huggins, Tara A. Miskovich, Jacklynn M. Fitzgerald, Kenneth P. Bennett, Jessica L. Krukowski, E. Kate Webb, Terri A Deroon-Cassini, Christine L. Larson

Psychology Faculty Research and Publications

Background: Little is known about what distinguishes those who are resilient after trauma from those at risk for developing posttraumatic stress disorder (PTSD). Previous work indicates white matter integrity may be a useful biomarker in predicting PTSD. Research has shown changes in the integrity of three white matter tracts—the cingulum bundle, corpus callosum (CC), and uncinate fasciculus (UNC)—in the aftermath of trauma relate to PTSD symptoms. However, few have examined the predictive utility of white matter integrity in the acute aftermath of trauma to predict prospective PTSD symptom severity in a mixed traumatic injury sample.

Method: Thus, the current study …


Stability Of Hippocampal Subfield Volumes After Trauma And Relationship To Development Of Ptsd Symptoms, C. N. Weis, E. Kate Webb, Ashley A. Huggins, Maddy Kallenbach, Tara A. Miskovich, Jacklynn M.

Stability Of Hippocampal Subfield Volumes After Trauma And Relationship To Development Of Ptsd Symptoms, C. N. Weis, E. Kate Webb, Ashley A. Huggins, Maddy Kallenbach, Tara A. Miskovich, Jacklynn M. Fitzgerald, Kenneth P. Bennett, Jessica L. Krukowski, Terri A Deroon-Cassini, Christine L. Larson

Psychology Faculty Research and Publications

Background

The hippocampus plays a central role in post-traumatic stress disorder (PTSD) pathogenesis, and the majority of neuroimaging research on PTSD has studied the hippocampus in its entirety. Although extensive literature demonstrates changes in hippocampal volume are associated with PTSD, fewer studies have probed the relationship between symptoms and the hippocampus’ functionally and structurally distinct subfields. We utilized data from a longitudinal study examining post-trauma outcomes to determine whether hippocampal subfield volumes change post-trauma and whether specific subfields are significantly associated with, or prospectively related to, PTSD symptom severity. As a secondary aim, we leveraged our unique study design sample …

Descriptive Assessment Of Conversational Skills: Towards Benchmarks For Young Adults With Social Deficits, Stephanie Hood, Britany M. Beauchesne, Tara A. Fahmie, Alexandra Go

Psychology Faculty Research and Publications

Descriptive assessments are necessary to identify social norms and establish a foundation for experimental analysis. Much of the social skills intervention literature involves goals that have been selected through interviews and direct observation of behavior without a reference to desired outcomes. The purpose of the current study was to extend research on descriptive assessments of conversations by including additional measures and examining conversational behavior across contexts. We conducted a descriptive assessment of social skills exhibited by 16 neurotypical young adults. Participants had 10-min conversations in groups and 1-on-1 with friends and novel individuals. We then assessed variability within and across …

Microsoft Excel is ubiquitous, cost-effective, and can be used to create publication-quality single-case design graphs. We systematically replicated the GraphPad Prism video tutorial by Mitteer et al. (2018) to teach 24 master's students to create multiple-baseline graphs using Excel 2016. Students' mean accuracy on the multiple-baseline graph was 25% in pretraining, 86% with the video tutorial, and 96% with the review checklist. Next, students used the same video tutorial to create multielement and reversal graphs. Students' mean accuracy on the multielement graph was 93% with video tutorial and 94% with review checklist, and accuracy on the reversal graph was 82% …


Five-Year Change In Body Mass Index Predicts Conversion To Mild Cognitive Impairment Or Dementia Only In Apoe Ɛ4 Allele Carriers, Kylie R. Kadey, John L. Woodard, Allison C. Moll, Kristy A. Nielson, J. Carson Smith, Sally Durgerian, Stephen M. Rao May 2021

Five-Year Change In Body Mass Index Predicts Conversion To Mild Cognitive Impairment Or Dementia Only In Apoe Ɛ4 Allele Carriers, Kylie R. Kadey, John L. Woodard, Allison C. Moll, Kristy A. Nielson, J. Carson Smith, Sally Durgerian, Stephen M. Rao

Psychology Faculty Research and Publications

Background:

Body mass index (BMI) has been identified as an important modifiable lifestyle risk factor for dementia, but less is known about how BMI might interact with Apolipoprotein E ɛ4 (APOE ɛ4) carrier status to predict conversion to mild cognitive impairment (MCI) and dementia.

Objective:

The aim of this study was to investigate the interaction between APOE ɛ4 status and baseline (bBMI) and five-year BMI change (ΔBMI) on conversion to MCI or dementia in initially cognitively healthy older adults.

Methods:

The associations between bBMI, ΔBMI, APOE ɛ4 status, and conversion to MCI or …


Circulating Endocannabinoids And Prospective Risk For Depression In Trauma-Injury Survivors, Jacklynn M. Fitzgerald, Samantha Chesney, Tara Sander Lee, Karen J. Brasel, Christine L. Larson, Cecilia J. Hillard, Terri A Deroon-Cassini May 2021

Circulating Endocannabinoids And Prospective Risk For Depression In Trauma-Injury Survivors, Jacklynn M. Fitzgerald, Samantha Chesney, Tara Sander Lee, Karen J. Brasel, Christine L. Larson, Cecilia J. Hillard, Terri A Deroon-Cassini

Psychology Faculty Research and Publications

Biological mechanisms associated with response to trauma may impact risk for depression. One such mechanism is endocannabinoid signaling (eCB), a neuromodulatory system comprised of the CB1 subtype of cannabinoid receptors (CB1R), encoded by the CNR1 gene, and two primary endogenous ligands: 2-arachidonoylglycerol (2-AG) and N-arachidonylethanolamine (AEA), hydrolyzed by monoacylglycerol lipase (gene name MGLL) and fatty acid amide hydrolase (gene name FAAH). Preclinical data suggest that eCB/CB1R signaling acts as a stress buffer and its loss or suppression increases depression-like behaviors. We examined circulating concentrations of the eCBs (2-AG and AEA) days and six months after a traumatic injury …

Ricketts, Christine Lochner, Dan J. Stein, Jan Stochl, Samuel R. Chamberlain, Jeremiah M. Scharf, Darin D. Dougherty, Douglas W. Woods, John Piacentini, Nancy Keuthen

Psychology Faculty Research and Publications

Body-focused repetitive behavior disorders (BFRBs) include Trichotillomania (TTM; Hair pulling disorder) and Excoriation (Skin Picking) Disorder (SPD). These conditions are prevalent, highly heterogeneous, under-researched, and under-treated. In order for progress to be made in optimally classifying and treating these conditions, it is necessary to identify meaningful subtypes. 279 adults (100 with TTM, 81 with SPD, 40 with both TTM and SPD, and 58 controls) were recruited for an international, multi-center between-group comparison using mixture modeling, with stringent correction for multiple comparisons. The main outcome measure was to examine distinct subtypes (aka latent classes) across all study participants using item-level data …


Exercise Training-Related Changes In Cortical Gray Matter Diffusivity And Cognitive Function In Mild Cognitive Impairment And Healthy Older Adults, Daniel D. Callow, Junyeon Won, Gabriel S. Pena, Leslie S. Jordan, Naomi A. Arnold-Nedimala, Yash Kommula, Kristy A. Nielson, J. Carson Smith Apr 2021

Exercise Training-Related Changes In Cortical Gray Matter Diffusivity And Cognitive Function In Mild Cognitive Impairment And Healthy Older Adults, Daniel D. Callow, Junyeon Won, Gabriel S. Pena, Leslie S. Jordan, Naomi A. Arnold-Nedimala, Yash Kommula, Kristy A. Nielson, J. Carson Smith

Psychology Faculty Research and Publications

Individuals with Mild Cognitive Impairment (MCI) are at an elevated risk of dementia and exhibit deficits in cognition and cortical gray matter (GM) volume, thickness, and microstructure. Meanwhile, exercise training appears to preserve brain function and macrostructure may help delay or prevent the onset of dementia in individuals with MCI. Yet, our understanding of the neurophysiological effects of exercise training in individuals with MCI remains limited. Recent work suggests that the measures of gray matter microstructure using diffusion imaging may be sensitive to early cognitive and neurophysiological changes in the aging brain. Therefore, this study is aimed to determine the …

Having No Words For Feelings: Alexithymia As A Fundamental Personality Dimension At The Interface Of Cognition And Emotion, Olivier Luminet, Kristy A. Nielson, Nathan Ridout

Psychology Faculty Research and Publications

This special issue brings together two important reviews and seven cutting-edge empirical papers concerning the influence of alexithymia on cognitive and emotional processing. Alexithymia is a multifaceted construct that is characterised by difficulties identifying one’s feelings; difficulties describing one’s feelings to others; and an externally focused, utilitarian cognitive style. In this paper, we begin by considering how emotion science has evolved in its understanding of personality traits, before highlighting the potential importance of alexithymia research for the field of cognition and emotion. After summarising the historical context of alexithymia research, we consider the contributions of the featured papers to the …

Event-Related Potentials, Inhibition, And Risk For Alzheimer’S Disease Among Cognitively Intact Elders, Kathleen Hazlett Elverman, Elizabeth Rose Paitel, Christina Marie Figueroa, Ryan J. Mckindles, Kristy A. Nielson

Psychology Faculty Research and Publications

Background:

Despite advances in understanding Alzheimer’s disease (AD), prediction of AD prior to symptom onset remains severely limited, even when primary risk factors such as the apolipoprotein E (APOE) ɛ4 allele are known.

Objective:

Although executive dysfunction is highly prevalent and is a primary contributor to loss of independence in those with AD, few studies have examined neural differences underlying executive functioning as indicators of risk for AD prior to symptom onset, when intervention might be effective.

Methods:

This study examined event-related potential (ERP) differences during inhibitory control in 44 cognitively intact older adults (20 ɛ4+, 24 ɛ4-), …


Cognitive-Emotional Processing In Alexithymia: An Integrative Review, Olivier Luminet, Kristy A. Nielson, Nathan Ridout Mar 2021

Cognitive-Emotional Processing In Alexithymia: An Integrative Review, Olivier Luminet, Kristy A. Nielson, Nathan Ridout

Psychology Faculty Research and Publications

Alexithymia is a multifaceted personality construct characterised by difficulties identifying one’s feelings and distinguishing them from bodily sensations, difficulties describing one’s feelings to others, and an externally oriented cognitive style. Over the past 25 years, a burgeoning body of research has examined how alexithymia moderates processing at the cognition–emotion interface. We review the findings in five domains: attention, appraisals, memory, language, and behaviours. The preponderance of studies linked alexithymia with deficits in emotion processing, which was apparent across all domains, except behaviours. All studies on behaviours and a proportion of studies in other domains demonstrated emotional over-responding. Analysis at the …


Applying The Vulnerability Stress Adaptation Model Of Marriage To Couples Raising An Autistic Child: A Call For Research On Adaptive Processes, Hillary Katherine Schiltz, Amy V. Van Hecke Mar 2021

Applying The Vulnerability Stress Adaptation Model Of Marriage To Couples Raising An Autistic Child: A Call For Research On Adaptive Processes, Hillary Katherine Schiltz, Amy V. Van Hecke

Psychology Faculty Research and Publications

Parents of children on the autism spectrum are particularly susceptible to strain in their romantic relationships due to unique risk factors. While some relationships deteriorate, however, others endure and thrive. The Vulnerability Stress Adaptation (VSA) Model of Marriage (Karney & Bradbury, 1995; Fig. 1) offers a framework to explain, not only poor marital outcomes, but also the process by which degradation of relationships occurs over time. The VSA Model posits that a combination of internal (within-person) vulnerabilities and external stressors influence relationship quality and, in turn, stability, by affecting couples' abilities to collaborate to adapt to stressors and solve problems …


The Role Of Loneliness As A Mediator Between Autism Features And Mental Health Among Autistic Young Adults, Hillary Schiltz, Alana J. Mcvey, Bridget Dolan Wozniak, Angela Haendel, Rachel Stanley, Alexis Arias, Nakia Gordon, Amy V. Van Hecke Feb 2021

The Role Of Loneliness As A Mediator Between Autism Features And Mental Health Among Autistic Young Adults, Hillary Schiltz, Alana J. Mcvey, Bridget Dolan Wozniak, Angela Haendel, Rachel Stanley, Alexis Arias, Nakia Gordon, Amy V. Van Hecke

Psychology Faculty Research and Publications

Autistic adults commonly experience anxiety and depression. These mental health concerns are often tied to social experiences, such that mental well-being can be supported by social connection and deteriorated by loneliness. The mediating role of social and emotional loneliness (i.e. social isolation and lack of emotional attachment, respectively) between autism features and mental health has yet to be empirically tested among autistic adults. Here, 69 autistic young adults completed self-report questionnaires assessing social contact (Friendship Questionnaire), autism features (Autism Quotient), mental health (Liebowitz Social Anxiety Scale, Social Phobia Inventory, Beck Depression Inventory), and loneliness (Social and Emotional Loneliness Scale for …


Dacc Resting State Functional Connectivity As A Predictor Of Pain Symptoms Following Motor Vehicle Crash: A Preliminary Investigation, Jacklynn M. Fitzgerald, Emily L. Belleau, Lauren E. Ehret, Colleen Trevino, Karen J. Brasel, Christine L. Larson, Terri A Deroon-Cassini Feb 2021

Dacc Resting State Functional Connectivity As A Predictor Of Pain Symptoms Following Motor Vehicle Crash: A Preliminary Investigation, Jacklynn M. Fitzgerald, Emily L. Belleau, Lauren E. Ehret, Colleen Trevino, Karen J. Brasel, Christine L. Larson, Terri A Deroon-Cassini

Psychology Faculty Research and Publications

There is significant heterogeneity in pain outcomes following motor vehicle crashes (MVCs), such that a sizeable portion of individuals develop symptoms of chronic pain months after injury while others recover. Despite variable outcomes, the pathogenesis of chronic pain is

currently unclear. Previous neuroimaging work implicates the dorsal anterior cingulate cortex (dACC) in adaptive control of pain, while prior resting state functional magnetic resonance imaging studies find increased functional connectivity (FC) between the dACC and regions involved in pain processing in those with chronic pain. Hyper-connectivity of the dACC to regions that mediate pain response may therefore relate to pain severity. …

Forecasting Chaotic Events And The Prediction Of A Rare Cognitive Ability, Stephen J. Guastello, William Futch, Lucas A. Mirabito, Dominique Green, Laura Marsicek, Brittany Witty

Psychology Faculty Research and Publications

People often live and work in chaotic environments, and thus need to forecast and control what will happen next. The management of chaos is an apparently rare skill, and it would be valuable to identify and develop this skill in the workforce. Untrained undergraduates (N = 147) forecasted number series from four chaotic attractors of varying levels of complexity. They contributed measurements of 16PF personality traits, general intelligence, field independence, and divergent thinking. The results indicated that field independence and personality traits associated with the creative personality profile were the most frequent correlates of performance on forecasting one to …


Synaptic Processes And Immune-Related Pathways Implicated In Tourette Syndrome, Douglas W. Woods Jan 2021

Synaptic Processes And Immune-Related Pathways Implicated In Tourette Syndrome, Douglas W. Woods

Psychology Faculty Research and Publications

Tourette syndrome (TS) is a neuropsychiatric disorder of complex genetic architecture involving multiple interacting genes. Here, we sought to elucidate the pathways that underlie the neurobiology of the disorder through genome-wide analysis. We analyzed genome-wide genotypic data of 3581 individuals with TS and 7682 ancestry-matched controls and investigated associations of TS with sets of genes that are expressed in particular cell types and operate in specific neuronal and glial functions. We employed a self-contained, set-based association method (SBA) as well as a competitive gene set method (MAGMA) using individual-level genotype data to perform a comprehensive investigation of the biological background …

This systematic review examined whether event-related potentials (ERPs) during higher cognitive processing can detect subtle, early signs of neurodegenerative disease. Original, empirical studies retrieved from PsycINFO and PubMed were reviewed if they analyzed patterns in cognitive ERPs (≥150 ms post-stimulus) differentiating mild cognitive impairment (MCI), Alzheimer’s disease (AD), or cognitively intact elders who carry AD risk through the Apolipoprotein-E ε4 allele (ε4+) from healthy older adult controls (HC). The 100 studies meeting inclusion criteria (MCI = 47; AD = 47; ε4+ = 6) analyzed N200, P300, N400, and occasionally, later components. While there was variability across studies, patterns of reduced …

The Latino population continues to underutilize mental health services at an alarming rate. The Attitudes Toward Seeking Professional Psychological Help Scale–Short Form (ATSPPH-SF) is one of the most commonly used instruments to assess help-seeking attitudes. The current study sought to evaluate the factor structure and test for the presence of differential item functioning on the ATSPPH-SF with a sample of Latino adult individuals across nativity status (U.S.- vs. foreign-born), language format (English vs. Spanish), and gender. The analyses revealed two relatively independent factors named Openness to Seeking Treatment and Value and Need in Seeking Treatment. Measurement equivalence and practical implications …
