Being Here And Now: The Benefits Of Belonging In Space And Time, Matthew Baldwin, Lucas A. Keefer

Faculty Publications

Research suggests that a sense of belonging is a critical prerequisite of happiness and well-being. While some have focused on belonging provided by relationships, other work demonstrates the value of belonging in certain places. In the current research we join these efforts to understand belonging by offering a novel framework for exploring an understudied but no less fundamental aspect of human experience—time. We situate this framework within an existential analysis of human action and test general predictions about the psychological value of experiencing a sense of belonging in time, what we call temporal rootedness. Two samples (Studies 1 …

Cognitive Impairments And Self-Reported Sleep In Early-Stage Parkinson’S Disease With Versus Without Probable Rem Sleep Behavior Disorder, Jonathan Trout, Taylor Christiansen, M. Brooks Bulkley, Jared J. Tanner, Christopher N. Sozda, Dawn Bowers, Daniel Kay

Faculty Publications

Parkinson’s disease (PD) is associated with cognitive and sleep impairments. The presence of rapid eye movement (REM) sleep behavior disorder (RBD) symptoms may represent a worse disease prognosis for PD individuals. We investigated cognitive functioning and self-reported sleep in early-stage PD individuals with (n = 19) or without (n = 31) probable RBD. Probable RBD was defined as >5 on the REM Sleep Behavior Disorder Screening Questionnaire. Inhibition, visuospatial cognitive abilities, working memory, sustained visual attention, verbal fluency, and episodic memory were assessed. Sleep impairments were assessed using the Pittsburgh Sleep Quality Index, Insomnia Severity Index, Epworth Sleepiness Scale, and …

Objective: To inform selection of physical measures for studies of ARDS survivors within 12 months of ARDS Methods: Secondary analysis of data from 6-month survivors participating in a U.S. multicenter prospective study (ARDSNet Long-Term Outcome Study [ALTOS], N=134) or a multi-site prospective study in Baltimore, MD (Improving Care of Acute Lung Injury Patients [ICAP], N=99). Physical measures, assessed at 6-month follow-up, were categorized according to the World HealthOrganization’s International Classification of Disability and Health: body functions and structures, activity, and participation. Patient-centered outcomes were evaluated at 6 and 12- months: survival, hospitalization, alive at home status, and health-related quality of …

Testing An Active Intervention To Deter Researchers' Use Of Questionable Research Practices, Samuel V. Bruton, M. Brown, Donald Sacco, R. Didlake

Faculty Publications

Introduction: In this study, we tested a simple, active “ethical consistency” intervention aimed at reducing researchers’ endorsement of questionable research practices (QRPs).

Methods: We developed a simple, active ethical consistency intervention and tested it against a control using an established QRP survey instrument. Before responding to a survey that asked about attitudes towards each of fifteen QRPs, participants were randomly assigned to either a consistency or control 3–5-min writing task. A total of 201 participants completed the survey: 121 participants were recruited from a database of currently funded NSF/NIH scientists, and 80 participants were recruited from a pool …

Faculty Publications

To the Editor: In response to Dr. Umberger’s comments on the Impact of Event Scale-Revised (IES-R) and the abbreviated 6-item IES (IES-6), we offer guidance about assessing post-traumatic stress disorder (PTSD) symptoms as part of the existing National Institutes of Health-funded core outcome measurement set (COMS) for clinical research in acute respiratory failure (ARF) survivors

Impact Of Critical Illness On Resource Utilization: A Comparison Of Use In The Year Before And After Icu Admission*, Eliot L. Hirshberg Md, Ms, Emily L. Wilson Mstat, Valoree Stanfield Ms, Kathryn G. Kuttler Phd, Sarah Majercik Md, Mba, Sarah J. Beesley Md, Ms, James Orme Md, Ramona O. Hopkins, Samuel M. Brown Md, Ms

Faculty Publications

Objectives:

Increasingly, patients admitted to an ICU survive to hospital discharge; many with ongoing medical needs. The full impact of an ICU admission on an individual’s resource utilization and survivorship trajectory in the United States is not clear. We sought to compare healthcare utilization among ICU survivors in each year surrounding an ICU admission.

Design:

Retrospective cohort of patients admitted to an ICU during one calendar year (2012) in a multipayer healthcare system. We assessed mortality, hospital readmissions (categorized by ambulatory care sensitive conditions and emergency department), and outpatient visits. We compared the proportion of patients with visits during the …

Superior Colliculus Lesions Lead To Disrupted Responses To Light In Diurnal Grass Rats (Arvicanthis Niloticus), Andrew J. Gall, Alyssa M. Goodwin, Ohanes S. Khacherian, Laura B. Teal

Faculty Publications

The circadian system regulates daily rhythms of physiology and behavior. Although extraordinary advances have been made to elucidate the brain mechanisms underlying the circadian system in nocturnal species, less is known in diurnal species. Recent studies have shown that retinorecipient brain areas such as the intergeniculate leaflet (IGL) and olivary pretectal nucleus (OPT) are critical for the display of normal patterns of daily activity in diurnal grass rats (Arvicanthis niloticus). Specifically, grass rats with IGL and OPT lesions respond to light in similar ways to intact nocturnal animals. Importantly, both the IGL and OPT project to one another …

The Effect Of Group Polarization On Opposition To Donald Trump, Marija A. Bekafigo, Elena V. Stepanova, Brian A. Eiler, Kenji Noguchi, Kathleen L. Ramsey

Faculty Publications

Using focus groups, we examined support and opposition for Donald Trump prior to the 2016 presidential election. When ingroup members participate in discussion, this conversation alone typically strengthens and intensifies members’ initial attitudes. We used a pre‐ to post‐focus‐group questionnaire to assess attitudes toward Trump, his campaign, and policies. We argue that group polarization influenced people’s opinions about Trump such that attitudes became more extreme after discussion with like‐minded individuals. We report changes for Trump nonsupporters for which group polarization occurred on attitudes toward illegal immigration, political correctness, the military, women, and veterans after the group discussion. For each, level …

Life After Pediatric Critical Illness: Risk Factors For Reduced Health-Related Quality Of Life And Functional Decline, Ramona O. Hopkins

Faculty Publications

Survivors of a critical illness are at risk to develop physical, cognitive, and psychological impairments that can persist for months to years after they leave the hospital. Health-related quality of life (HRQL) and functional abilities are important measures of outcomes after a critical illness, as they reflect not only the effects of the critical illness, its treatment, and comorbid illness but also physical disability, cognitive impairment, and psychological disorders (depression, anxiety, and post-traumatic stress disorder) after a critical illness in adults (1). A review of HRQL in 557 adult survivors of acute respiratory distress syndrome found a substantially lower HRQL …

Early Negative Affect In Males And Females With Fragile X Syndrome: Implications For Anxiety And Autism, Carla A. Will, Abigail L. Hogan, Elizabeth A. Will, Samuel Mcquillin, Bridgette L. Kelleher, Jane E. Roberts

Faculty Publications

Background Fragile X syndrome (FXS) is a genetic disorder that is highly comorbid with anxiety and autism spectrum disorder (ASD). Elevated negative affect in young children has been associated with increased risk for both anxiety and ASD; however, these relations remain poorly understood in FXS.

Methods The present prospective longitudinal study examined the trajectory of negative affect from infancy through preschool in males and females with FXS and typical development and its relation to anxiety and ASD.

Results Results indicate a complex association reflecting group, developmental, and sex effects. Specifically, the group with FXS displayed a trajectory of increasing negative …

Situational Factors Influencing Receptivity To Bullshit, Mitch Brown, Lucas A. Keefer, Shelby J. Mcgrew

Faculty Publications

Individuals are motivated to maintain a sense of meaning, and enact cognitive processes to do so (e.g., perceiving structure in the environment). This motivation to find meaning may ultimately impact humans’ interpretation of "bullshit", statements intended to convey profundity without any meaning. Conversely, subtle cues threatening the meaningfulness of bullshit may elicit greater skepticism. Three studies tested situational factors predicted to heighten or diminish susceptibility to bullshit by changing motivations to seek meaning. We employed diverse methods including symbolic meaning threat (Study 1), social exclusion (Cyberball; Study 2), and manipulating cognitive fluency (Study 3). Taken together, the results indicate basic …

Faculty Publications

Objective: Data are lacking regarding implementation of novel strategies such as follow-up clinics and peer support groups, to reduce the burden of post-intensive care syndrome. We sought to discover enablers that helped hospital-based clinicians establish post-ICU clinics and peer support programs, and identify barriers that challenged them.

Design: Qualitative inquiry. The Consolidated Framework for Implementation Research was used to organize and analyze data.

Setting: Two learning collaboratives (ICU follow-up clinics and peer support groups), representing 23 sites, across three continents.

Subjects: Clinicians from 23 sites. Measurement and Main Results: Ten enablers and nine barriers to implementation of ICU follow-up clinics …

Functional And Anatomical Variations In Retinorecipient Brain Areas In Arvicanthis Niloticus And Rattus Norvegicus: Implications For The Circadian And Masking Systems, Dorela D. Shuboni-Mulligan, Breyanna L. Cavanaugh, Anne Tonson, Erik M. Shapiro, Andrew J. Gall

Faculty Publications

Daily rhythms in light exposure influence the expression of behavior by entraining circadian rhythms and through its acute effects on behavior (i.e., masking). Importantly, these effects of light are dependent on the temporal niche of the organism; for diurnal organisms, light increases activity, whereas for nocturnal organisms, the opposite is true. Here we examined the functional and morphological differences between diurnal and nocturnal rodents in retinorecipient brain regions using Nile grass rats (Arvicanthis niloticus) and Sprague-Dawley (SD) rats (Rattus norvegicus), respectively. We established the presence of circadian rhythmicity in cFOS activation in retinorecipient brain regions in …

Firearm Availability And Storage Practices Among Military Personnel Who Have Thought About Suicide, Craig J. Bryan, Annabelle O. Bryan, Michael D. Anestis, Lauren Khazem, Julia Harris, Alexis May, Cynthia Thomsen

Faculty Publications

More than 60% of US military suicides occur at home and involve a firearm. Nearly all military firearm suicides (95%) involve a personally owned firearm. Nonmilitary data indicate that the risk of suicide is 6 times higher in households with a firearm, although this risk may be reduced if the firearms are kept unloaded and/or locked. Because attempts using firearms have very high fatality rates, safe firearm storage practices could be an important component of comprehensive suicide prevention in the military. This study examined associations of firearm ownership and storage practices with suicidal thoughts and behaviors among military personnel.

Reports Of Recovered Memories Of Childhood Abuse In Therapy In France, Olivier Dodier, Lawrence Patihis, Mélany Payoux

Faculty Publications

Recovered memories of abuse in therapy are especially controversial if the clients were not aware they were abused before therapy. In the past, such memory recovery has led to legal action, as well as a debate about whether such memories might be repressed, forgotten, or false memories. More than two decades after the height of the controversy, it is unclear to what degree such memories are still recovered today, and to what extent it occurs in France. In our French survey of 1312 participants (M_age = 33; 53% female), 551 reported having done therapy at some point. Of …

Effects Of A Brief Mindfulness Induction On Death-Related Anxiety, David M. Schultz, Randolph C. Arnau

Faculty Publications

This study examined effects of a mindfulness induction on proximal and distal defense responses to mortality salience and negative affect. Three experimental conditions were included: mindfulness, mind-wandering, and worrying. Participants in the mindfulness condition underwent a mindfulness induction at the experiment’s outset, while participants in the other two conditions underwent a mind-wandering or worry induction. Inductions involved following guided audio instructions presented via headphones. All conditions (N = 77) underwent a mortality salience induction after experimental manipulation, involving a written exercise pertaining to one’s death. Results indicated fewer proximal responses in the mindfulness and mind-wandering groups, compared with the worrying …

Let It Rest: Sleep And Health As Positive Correlates Of Forgiveness Of Others And Self-Forgiveness, Loren Toussaint, Andrew J. Gall, Alyssa Cheadle, David R. Williams

Faculty Publications

Objective: The present study examined forgiveness of others, self-forgiveness, sleep, and health in a nationally representative sample of United States adults. It was hypothesised that sleep would mediate the associations of forgiveness of others and self-forgiveness with health.

Design: A nationally representative survey of 1,423 United States adults.

Main Outcome Measures: Measures included forgiveness of others, self-forgiveness, sleep quantity, sleep quality, psychological distress, life satisfaction, and self-rated physical health.

Results: Forgiveness of others (β = .20, p < .001) and self-forgiveness (β = .11, p < .01) were associated with sleep and forgiveness of others (β = .24, p < .001) and self-forgiveness (β = .27, p < .001) were associated with health. Sleep was associated with health (β = .45, p < .001) and also acted as a mediator of the associations of forgiveness of others (β = .09, p < .01) and self-forgiveness (β = .05, p < .01) with health.

Conclusions: Forgiveness of others and self-forgiveness may attenuate emotions such as anger, regret, and rumination and provide …

Cardiovascular Factors Moderate The Association Of Infection Burden With Cognitive Function In Young To Middle-Aged U.S. Adults, Bruce L. Brown, Shawn D. Gale, Lance D. Erickson, Dawson W. Hedges, Andrew N. Berrett, Evan L. Thacker

Faculty Publications

Background: Infectious diseases might affect cognitive aging and dementia risk, possibly via neuroinflammation. Similarly, risk factors for cardiovascular and cerebrovascular diseases are associated with cognitive function and dementia. We hypothesized that cardiovascular risk factors moderate the association of exposure to infectious diseases with cognitive function.

Methods: We studied 5662 participants aged 20 to 59 years from the third National Health and Nutrition Examination Survey (1988–1994) in the United States. We used linear regression to investigate whether the Framingham general cardiovascular risk index moderated the association of infection burden based on exposure to eight different infectious diseases with cognitive functioning as …

Successful Weight Loss Initiation And Maintenance Among Adolescents With Overweight And Obesity: Does Age Matter?, Diana Rancourt, Chad D. Jensen, Kara Mcrae Duraccio, E. Whitney Evans, Rena R. Wing, Elissa Jelalian

Faculty Publications

Background—Treatments for adolescents with overweight/obesity demonstrate mixed success, which may be due to a lack of consideration for developmental changes during this period. Potential developmental differences in weight loss motivations, weight maintenance behaviors, and the role of parents in these efforts were examined in a sample of successful adolescent weight losers.

Methods—Participants enrolled in the Adolescent Weight Control Registry (n = 49) self-reported demographic information and weight history, reasons for weight loss and weight control, weight loss approach and weight maintenance strategies, and perceived parental involvement with weight loss. Associations between age at weight loss initiation and the aforementioned factors …

Infant Social Avoidance Predicts Autism But Not Anxiety In Fragile X Syndrome, Jane E. Roberts, Hayley Crawford, Elizabeth A. Will, Abigail L. Hogan, Samuel Dale Mcquillin, Bridgette L. Tonnsen, Shannon O'Connor, Douglas A. Roberts, Alexis M. Brewe

Faculty Publications

Objective: Autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and anxiety are three of the most common childhood psychiatric disorders. Early trajectories of social avoidance have been linked with these psychiatric disorders in previous studies, but it remains unclear how social avoidance differentially predicts comorbid disorders in a high-risk genetic subgroup. Here, we delineate the association between trajectories of social avoidance from infancy and subsequent ASD, ADHD, and anxiety outcomes at preschool in children with fragile X syndrome (FXS), a well-characterized single-gene disorder highly associated with social avoidance as well as elevated rates of ASD, ADHD, and anxiety.

Method: Males with …

Ethnic-Racial Socialization In Early Childhood: The Implications Of Color-Consciousness And Colorblindness For Prejudice Development, Flora Farago, Kimberly Leah Davidson, Christy M. Byrd

Faculty Publications

This chapter outlines how early childhood teachers can bring children into conversations surrounding race and racism by drawing on literature on how parents of color discuss these topics. Although educators’ practices surrounding race and racism remain largely unexplored, decades of developmental psychological research indicate that parents of color engage in ethnic-racial socialization practices that are beneficial for children (Hughes et al., 2006). The established dimensions of parental ethnic-racial socialization include (1) cultural socialization, or teaching children about their ethnic heritage and instilling ethnic pride; (2) preparation for bias, or teaching children about racism and preparing them to face discrimination; (3) …

The Effects Of Ambient Temperature And Lighting Intensity On Wheel-Running Behavior In A Diurnal Rodent, The Nile Grass Rat (Arvicanthis Niloticus), Garrett M. Fogo, Alyssa M. Goodwin, Ohanes S. Khacherian, Brandi J. Ledbetter, Andrew J. Gall

Faculty Publications

Environmental conditions, such as the light-dark cycle and temperature, affect the display of circadian rhythmicity and locomotor activity patterns in mammals. Here, we tested the hypothesis that manipulating these environmental conditions would affect wheel-running activity patterns in a diurnal rodent, the Nile grass rat (Arvicanthis niloticus). Grass rats are diurnal in the field, however, a subset switch from a day-active pattern to a night-active pattern of activity after the introduction of a running wheel. The mechanism of this chronotype switch remains largely unknown. In the present study, grass rats were presented with running wheels in 12:12 light-dark conditions. First, subjects …

Steadfast Standards Or Fluctuating Fancies? Stability And Change In People’S Mate Criteria Over 27 Months, Carrie A. Bredow, Nicole Hames

Faculty Publications

Although research on mate preferences has been built on the assumption that the criteria people report at one point in time should predict their future partnering behavior, little is known about the temporal stability of people’s standards. Using survey data collected at four time points from 285 originally unmarried individuals, this study examined the rank-order, meanlevel, individual-level and ipsative stability of people’s mate criteria over 27 months. Overall, reported standards exhibited moderate to high baseline stability, with rank-order and ipsative estimates comparable to those reported for personality traits. At the same time, mean- and individual-level analyses revealed small, but significant, …

Difference Of Opinion: Spousal Influence On Cancer Risk-Reducing Behavior, Wendy C. Birmingham, Maija Reblin, Wendy Kohlmann, Tyler Graff

Faculty Publications

Marriage is consistently associated with better health outcomes. Spouses' attempts to influence partners' lifestyle and general health behaviors may contribute to this effect, although partners may not be aware of this influence. Spousal worry of a cancer diagnosis for an at-risk partner may factor into attempts to influence. An examination of spousal worry and influence on lifestyle choices, general health behaviors, and cancer screening adherence for partners at higher risk of colorectal cancer may shed light on spousal influence and partners' perceptions of influence. Methods: A mixed-method design assessed cancer worry and spousal influence for risk-reducing behavior in first-degree relatives …

Enhanced Memory For Fair-Related Faces And The Role Of Trait Anxiety, Gewnhi Park, Benjamin U. Marsh, Elisha J. Johnson

Faculty Publications

The current research examined whether fair consideration—a social norm that people inherently prefer to confirm—would modulate face recognition. Each neutral face was associated with fair or unfair offers via an economic decision task, the Ultimatum Game (UG) task. After the UG, participants were asked to identify the faces of proposers who made different offers. Enhanced memory was observed for fair-related compared to unfair-related faces. Furthermore, high trait anxiety was associated with reduced memory for fair-related faces. These results were further confirmed by signal detection theory. The current research provided initial evidence that people showed enhanced memory for faces that made …

Longitudinal Health Outcomes And Treatment Utilization Among Emerging, Early-Mid, And Older Rural Adults Using Stimulants, Erin L. Woodhead, Brenda Booth, Christine Timko, Amanda Tjemsland, Xiaotong Han, Michael Cucciare

Faculty Publications

There is limited knowledge about age-related differences in health outcomes and treatment utilization among rural stimulant users. The current study examined physical health, mental health, and treatment utilization (hospital, mental health, and substance use care) among 710 stimulant users living in rural areas of the United States. Generalized estimating equations (GEE) were used to examine associations between age and physical health, mental health, and treatment utilization over a 3-year period. Analyses controlled for participants’ gender, race, and education. To capture age-related differences, participants were grouped into emerging adults (18–25 years old, n = 223), early-mid adults (26–44 years old; n …

Impact Of Acute Sleep Restriction On Cerebral Glucose Metabolism During Recovery Non-Rapid Eye Movement Sleep Among Individuals With Primary Insomnia And Good Sleeper Controls, Daniel Kay, Helmet T. Karim, Brant P. Hasle, Jeffrey A. James, Anne Germain, Martica H. Hall, Peter L. Franzen, Julie C. Price, Eric A. Nofzinger, Daniel J. Buysse

Faculty Publications

Background: Restricting time in bed improves insomnia symptoms, but the neural mechanisms for this effect are unknown. Total and partial acute sleep restriction may be useful paradigms for elucidating these effects. We examined the impact of acute sleep restriction on cerebral glucose metabolism during non-rapid eye movement (NREM) sleep in individuals with primary insomnia (PI; n=17) and good sleep (GS; n=19).

Methods: Participants underwent [18F]fluorodeoxyglucose positron emission tomography (FDGPET) scans during baseline and recovery NREM sleep following one night of partial or total sleep restriction. We compared group differences (PI vs. GS) in baseline-recovery changes, as well as main effects …

Multifractality Of Posture Modulates Multisensory Perception Of Stand-On-Ability, Jonathan K. Doyon, Alen Hajnal, Tyler Surber, Joseph D. Clark, Damian G. Kelty-Stephen

Faculty Publications

By definition, perception is a multisensory process that unfolds in time as a complex sequence of exploratory activities of the organism. In such a system perception and action are integrated, and multiple energy arrays are available simultaneously. Perception of affordances interweaves sensory and motor activities into meaningful behavior given task constraints. The present contribution offers insight into the manner in which perception and action usher the organism through competent functional apprehension of its surroundings. We propose that the tensegrity structure of the body, manifested via multifractality of exploratory bodily movements informs perception of affordances. The affordance of stand-on-ability of ground …

Supportive Hand-Holding Attenuates Pupillary Responses To Stress In Adult Couples, Wendy C. Birmingham, Tyler C. Graff, Steven G. Luke

Faculty Publications

Background

Social relationships, particularly marriage, have been shown to ameliorate the potentially pathogenic impact of stressful events but prior research has been mostly aimed at downstream effects, with less research on real-time reactivity. Pupillometry is an innovative procedure that allows us to see the effects of acute stress in real time. The muscles that control pupil size are linked to the autonomic nervous system, so that when stressed, the pupils dilate; this occurs within 200ms. This quick response allows us to see the immediate effects of acute stress on the autonomic nervous system (ANS), and the real-time effects of social …
