Don’T Let Covid-19 Disrupt Campus Climate Surveys Of Sexual Harassment, Kathryn Holland, Lilia M. Cortina, Vicki J. Magley, Arielle L. Baker, Frazier F. Benya

Department of Psychology: Faculty Publications

Surveying a campus community about sexual harassment can be a daunting task during normal times. It’s especially daunting during a pandemic. Institutional leaders may balk at committing scarce resources to survey efforts. Some may wonder how to interpret results that look dramatically different from prior assessments. Also, they may worry about adding to the burdens of already stressed staff, faculty, and students. Indeed, these concerns and complexities came up recently within the work of the National Academies’ Action Collaborative on Preventing Sexual Harassment in Higher Education (1).

For the reasons outlined above, sexual harassment surveys should continue in higher education, …

Machine Learning-Based Classification Of Viewing Behavior Using A Wide Range Of Statistical Oculomotor Features, Timo Kootstra, Jonas Teuwen, Jeroen Goudsmit, Tanja Nijboer, Michael D. Dodd, Stefan Van Der Stigchel

Department of Psychology: Faculty Publications

Since the seminal work of Yarbus, multiple studies have demonstrated the influence of task-set on oculomotor behavior and the current cognitive state. In more recent years, this field of research has expanded by evaluating the costs of abruptly switching between such different tasks. At the same time, the field of classifying oculomotor behavior has been moving toward more advanced, data-driven methods of decoding data. For the current study, we used a large dataset compiled over multiple experiments and implemented separate state-of-the-art machine learning methods for decoding both cognitive state and task-switching. We found that, by extracting a wide range of …

Vestibular Evoked Myogenic Potential (Vemp) Test-Retest Reliability In Children, Elizabeth Fuemmeler, Amanda Rodriquez, Megan Thomas, Tom Creutz, Denis Fitzpatrick, Kristen L. Janky

Department of Psychology: Faculty Publications

Objective—Vestibular evoked myogenic potentials (VEMPs) are short-latency muscle potentials measured from the neck (cervical VEMP; cVEMP) or under the eyes (ocular VEMP; oVEMP), which provide information regarding function of the saccule and utricle, respectively. VEMPs are reliable when performed in adults; however, reliability of VEMPs in children is unknown. Therefore, the purpose of the study was to determine the test-retest reliability of c- and oVEMP testing in normal control children.

Study Design—Prospective.

Setting—Hospital.

Patients—Ten adults, 14 adolescent children and 13 young children with normal hearing.

Interventions—c- and oVEMP testing were completed across two test sessions …

Psychological And Neurobiological Mechanisms Underlying The Decline Of Maternal Behavior, Ming Li

Department of Psychology: Faculty Publications

The maternal behavior decline is important for the normal development of the young and the wellbeing of the mother. This paper reviews limited research on the factors and mechanisms involved in the rat maternal behavior decline and proposes a multi-level model. Framed in the parent-offspring conflict theory (an ultimate cause) and the approach-withdrawal model (a proximate cause), the maternal behavior decline is viewed as an active and effortful process, reflecting the dynamic interplay between the mother and her offspring. It is instigated by the waning of maternal motivation, coupled with the increased maternal aversion by the mother in responding to …

Variability In The Analysis Of A Single Neuroimaging Dataset By Many Teams, Rotem Botvinik-Nezer, Tom Schonberg, Russell A. Poldrack, Zachary J. Cole, Matthew R. Johnson, Phui Cheng Lim, Evan N. Linz, Douglas H. Schultz, Joshua E. Zosky, Narps Management Team, Jean M. Vettel, More Than 100 Other Co-Authors

Department of Psychology: Faculty Publications

Data analysis workflows in many scientific domains have become increasingly complex and flexible. To assess the impact of this flexibility on functional magnetic resonance imaging (fMRI) results, the same dataset was independently analyzed by 70 teams, testing nine ex-ante hypotheses. The flexibility of analytic approaches is exemplified by the fact that no two teams chose identical workflows to analyze the data. This flexibility resulted in sizeable variation in hypothesis test results, even for teams whose statistical maps were highly correlated at intermediate stages of their analysis pipeline. Variation in reported results was related to several aspects of analysis methodology. Importantly, …

Corrigendum: A Close And Supportive Interparental Bond During Pregnancy Predicts Greater Decline In Sexual Activity From Pregnancy To Postpartum: Applying An Evolutionary Perspective, Tierney K. Lorenz, Erin L. Ramsdell, Rebecca L. Brock

Department of Psychology: Faculty Publications

A common topic for advice given to parents after childbirth – both from relationship experts and popular media – is how to “bounce back” to one’s pre-pregnancy sexuality, with warnings that postpartum declines in sexual frequency will take a serious toll on one’s relationship. However, these admonishments may not accurately reflect the ways in which the unique reproductive context of pregnancy and the postpartum transition alter associations between sexual frequency and relationship quality. Evolutionary perspectives on reproductive strategies would suggest that in the postpartum context, decreased sexual activity would help target parental investment in the current offspring (rather than creating …

5-Ht2a Receptors Modulate Dopamine D2-Mediated Maternal Effects, Jun Gao

Department of Psychology: Faculty Publications

Serotonin 5-HT2A receptors are expressed throughout the mesolimbic and mesocortical dopamine pathways, and manipulation of this receptor system has a profound impact on dopamine functions and dopamine-mediated behaviors. It is highly likely that 5-HT2A receptors may also modulate the D2-mediated maternal effects. The present study investigated this issue and also explored the possible behavioral mechanisms. We tested the effects of two D2 drugs (an agonist quinpirole: 0.5, 1.0 mg/kg, and a potent D2 antagonist haloperidol: 0.05, 0.10 mg/kg, sc) and their combinations with two 5-HT2A drugs (a selective 5-HT2A agonist TCB-2: 2.5 mg/kg, and 5-HT2A antagonist MDL100907, 1.0 mg/kg, sc) …

The Dark Side Of Helping Behaviors: Partner Support Increases Daily Alcohol Use In Outpatients With A History Of Alcohol Dependence, Frances C. Calkins, Rebecca L. Brock

Department of Psychology: Faculty Publications

The primary goal of the present study was to systematically investigate the role of intimate partner support in alcohol use and to examine whether partner support serves a maladaptive function among individuals with a history of alcohol dependence. This goal was pursued in a sample of low-income outpatients because of increased risk for chronic stress and alcohol use disorders among this population. We implemented a comprehensive, multimethod assessment of partner support and ecological momentary assessments of alcohol use over 14 consecutive days. Results demonstrate the potential “dark side” of helping behaviors that has been proposed in recent literature. Specifically, in …

Testing Traditional Machismo And The Gender Role Strain Theory With Mexican Migrant Farmworkers, Laura M. Acosta, Arthur R. Andrews Iii, M. Natalia Acosta Canchila, Athena K. Ramos

Department of Psychology: Faculty Publications

The current study examines the moderating role of traditional machismo on mental health outcomes. We hypothesized that machismo would enhance the effects of stressors that are incongruent with traditional machismo beliefs (discrimination, adverse childhood experiences [ACEs], and fear of deportation) on depression and anxiety outcomes but would not enhance stressors that are congruent (harsh working conditions and poverty) on depression and anxiety. Participants were 190 male Mexican migrant farmworkers. As hypothesized, endorsing high traditional machismo was associated with stronger effects of fear of deportation and discrimination on depression outcomes compared with low traditional machismo. The interaction of machismo and …

Smokers’ Reports On Receiving A Doctor’S Advice To Quit Smoking; Receiving The Advice Is More Prevalent Among Smokers With Crohn’S Disease Relative To Smokers With Ulcerative Colitis, Julia N. Soulakova, Le-Chu Su, Lisa J. Crockett

Department of Psychology: Faculty Publications

Receiving a doctor’s advice to quit smoking is an important predictor for improving smokers’ intentions to quit smoking and successful smoking cessation. We examined reports of smokers with Crohn’s Disease (CD) and Ulcerative Colitis (UC) regarding receiving a doctor’s advice to quit smoking in the past 12 months, and eval-uated the differences in the rates of receiving the advice between the CD and UC patients. The data were retrospectively reported by CD and UC patients (n = 453) who self-identified as current smokers in online assessments conducted by IBD Partners in the period from 2011 to 2014 in the USA. …

Predictors And Impact Of Psychotherapy Side Effects In Young Adults, Tierney K. Lorenz

Department of Psychology: Faculty Publications

What should we tell our younger clients—who may or may not have chosen to come to therapy—about possible risks of engaging in psychotherapy? To explore this question, we examined psychotherapy side effects in 366 young adults with a history of psychotherapy or counseling. Psychotherapy side effects were common, with 41% of participants reporting at least one. Perceived lack of control over the decision of when and how to engage in therapy was the strongest predictor of experiencing therapy side effects. Of the different kinds of side effects, feeling that therapy had gone on too long and experiencing worsening of existing …

Adrenocortical Attunement, Reactivity, And Potential Genetic Correlates Among Parent–Daughter Dyads From Low-Income Families, Jennifer Byrd-Craven, Michael M. Criss, Jessica L. Calvi, Lixian Cui, Amanda Baraldi, Amanda Sheffield Morris

Department of Psychology: Faculty Publications

Examining the multitude of influences on the development of adolescent stress responses, especially among low-income families, is a critical and understudied topic in the field. The current study examined cortisol attunement between adolescent girls and parents (mostly mothers) from predominantly low-income, single parent, ethnic minority families before and after an in-laboratory disagreement discussion task. The sample consisted of 118 adolescents (M_age = 13.79 years, 76.3% ethnic minorities, 23.7% European Americans) and primary caregivers (M_age = 40.62 years; Mdn yearly income = $24,000; 43.2% single parents; 50% living below poverty line). We investigated oxytocin receptor (OXTR rs53576) …

Assessing The Feasibility Of A Life History Calendar To Measure Hiv Risk And Health In Older South Africans, Enid Schat, Lucia Knight, Robert F. Belli, Sanyu A. Mojola

Department of Psychology: Faculty Publications

Life history calendars capture patterns of behavior over time, uncovering transitions and trajectories. Despite the growing numbers of older persons living with HIV in southern Africa, little is known about how HIV testing and risk unfold in this population. Operationalizing a life course approach with the use of an innovative Testing and Risk History Calendar [TRHC], we collected pilot data on older South Africans’ risk and HIV testing. We found older persons were able to provide (1) reference points to facilitate recall over a 10-year period, (2) specifics about HIV tests during that decade, and (3) details that contextualize the …

Identifying And Addressing Barriers To Treatment For Child Sexual Abuse Survivors And Their Non-Offending Caregivers, Kate Theimer, Akemi E. Mii, Emily Sonnen, Kelsey Mccoy, Katie Meidlinger, Brittany Biles, T. Zachary Huit, Mary F. Flood, David J. Hansen

Department of Psychology: Faculty Publications

Mental health treatment is a critical part of an effective and compassionate response to the disclosure of child sexual abuse (CSA). Given the vast negative consequences for children and families following CSA, engagement in treatment can benefit youth and their non-offending caregivers. Yet, these families face unique barriers to treatment initiation, adherence, and effectiveness. The identification of these barriers allows clinicians, researchers, and policy makers to increase treatment utilization, engagement, and value. The current review and its recommendations derive from the existing literature combined with knowledge gained from a clinical research team with more than 20 years of experience offering …

Serotonin 5-Ht2a And 5-Ht2c Receptors Regulate Rat Maternal Behavior Through Distinct Behavioral And Neural Mechanisms, Jun Gao, Lina Nie, Yu Li, Ming Li

Department of Psychology: Faculty Publications

Serotonin 5-HT_2A and 5-HT_2C receptors play important yet distinctive roles in the regulation of rat maternal behavior. The present study investigated their neural substrates and explored the possible behavioral mechanisms (i.e., behavioral organization or maternal motivation). Sprague-Dawley postpartum females were microinjected with either a selective 5-HT_2A agonist (TCB-2, 0.4 or 4.0 μg/side) or a 5-HT_2C agonist (MK212, 2.5 or 5.0 μg/side) into the medial prefrontal cortex (mPFC) or ventral tegmental area (VTA). Ten and 60 min later, their maternal activities were observed in the home cage; and their motivational responses towards pups were examined in a …

Early Head Start Service Use By Families With Court-Substantiated Maltreatment, Alayna Schreier, Kelsey Mccoy, Mary F. Flood, Brian Wilcox, David J. Hansen

Department of Psychology: Faculty Publications

Early Head Start (EHS) is an evidence-based intervention program for at-risk children birth through three that seeks to improve child and family well-being. There is little research to date examining the prevalence of child maltreatment among families enrolled in EHS and the extent to which maltreatment is associated with receipt of programs and services available to EHS families. This study sought to (a) identify the prevalence of court substantiated maltreatment in EHS families; and (b) determine the association between substantiated maltreatment and use of EHS program and community-linked services. To answer these questions, archival program and clinical service records and …

Attributions Of Blame In A Hypothetical Child Sexual Abuse Case: Roles Of Behavior Problems And Frequency Of Abuse, Kate Theimer, David J. Hansen

Department of Psychology: Faculty Publications

Youth who are blamed for their sexual abuse may experience increased negative outcomes, such as amplified self-blame. Similarly, blaming nonoffending parents can impede their ability to support their child following disclosure. Understanding the factors that influence how people perceive victim, caregiver, and perpetrator responsibility is imperative for the protection and treatment of families who have experienced sexual abuse. Little research has explored victim and abuse characteristics that influence the perception of sexual abuse. As such, the purpose of this study was to examine the roles of behavior problems and frequency of abuse in the attribution of blame in a hypothetical …

Role Of Brain Derived Extracellular Vesicles In Decoding Sex Differences Associated With Nicotine Self-Administration, Sneh Koul, Victoria L. Schaal, Subhash Chand, Steven T. Pittenger, Neetha Nanoth Vellichirammal, Vikas Kumar, Chittibabu Guda, Rick A. Bevins, Sowmya V. Yelamanchili, Gurudutt Pendyala

Department of Psychology: Faculty Publications

Smoking remains a significant health and economic concern in the United States. Furthermore, the emerging pattern of nicotine intake between sexes further adds a layer of complexity. Nicotine is a potent psychostimulant with a high addiction liability that can significantly alter brain function. However, the neurobiological mechanisms underlying nicotine’s impact on brain function and behavior remain unclear. Elucidation of these mechanisms is of high clinical importance and may lead to improved therapeutics for smoking cessation. To fill in this critical knowledge gap, our current study focused on identifying sex-specific brain-derived extracellular vesicles (BDEV) signatures in male and female rats post …

Definitions Of Water Quality: A Survey Of Lake-Users Of Water Quality-Compromised Lakes, Ashley Votruba, Jessica R. Corman

Department of Psychology: Faculty Publications

Understanding and defining water quality is an important precursor for influencing pro-environmental behavior and accurately assessing potential outcomes of human–lake interactions. This study surveyed 82 lake-users in Nebraska regarding their definitions of water quality and the importance of various water quality features to determine if lake-users’ definitions align with complex and multi-faceted governmental and scientific definitions. Survey sites included two recreational reservoirs (e.g., boating and fishing), Holmes Lake (urban watershed) and Branched Oak Lake (agricultural watershed). The biological and chemical parameters are similar between the lakes and both lakes were listed as “impaired” on the Section 303(d) (United States Environmental …

How Cultural Orientation And Self-Compassion Shape Objectified Body Consciousness For Women From America, Belgium, Russia, And Thailand, Robin Wollast, Abigail R. Riemer, Sarah Gervais, Lusine Grigoryan, Philippe Bernard, Olivier Klein

Department of Psychology: Faculty Publications

According to objectification theory, being treated as an object leads women to engage in self-objectification, which in turn increases body surveillance and body shame, impairing women’s mental health. While most studies focusing on self-objectification rely heavily on Western populations that emphasize individualism, the current work investigates the phenomenon of body surveillance and body shame in a cross-cultural framework, involving a comparison between American, Belgian, Russian, and Thai women (N = 605). This study aims to highlight two predictors – cultural orientation and self-compassion. Results indicate that greater endorsement of vertical individualism is related to body surveillance for American, Belgian, …

Moving Beyond Executive Functions: Challenge Preference As A Predictor Of Academic Achievement In Elementary School, Michael J. Sulik, Jenna E. Finch, Jelena Obradović

Department of Psychology: Faculty Publications

Intrinsic motivation and executive functions (EFs) have been independently studied as predictors of academic achievement in elementary school. The goal of this investigation was to understand how students’ challenge preference (CP), an aspect of intrinsic motivation, is related to academic achievement while accounting for EFs as a confounding variable. Using data from a longitudinal study of 569 third-, fourth-, and fifth-graders (50% female), we tested students’ self-reported CP as a predictor of mathematics and English language arts (ELA) achievement in multilevel models that controlled for school fixed effects and student demographic characteristics. CP was positively associated with mathematics and ELA …

Maternal Depression And Breastfeeding In Home Visitation, Francesca A. Scheiber, Lisa S. Segre, Michael W. O'Hara, Darby Taylor, Rebecca L. Brock

Department of Psychology: Faculty Publications

Background: Home visitation is a popular mechanism for supporting parents and their young children. Breastfeeding is often promoted by home visitors due to its health benefits. However, maternal depression may interfere with breastfeeding. Thus, home visitors may be attempting to encourage health-promoting behaviors like breastfeeding, but maternal depression may interfere with engagement in those behaviors. Method: The data for this study were provided by the Des Moines Healthy Start and the Empowerment Family Support Project (DMHSP). We analyzed the relation between depression and breastfeeding for 364 women. Results: First, rates of elevated depression scores in this sample of women (8.7%–21.4% …

Social Responsiveness And Objectification: The Moderating Roles Of Serotonin Transporter And Serotonin Receptor 2a Genotypes In An Objectification Theory Model Of Disordered Eating, Grace A. Sullivan, Sarah J. Gervais, Rebecca L. Brock, Scott F. Stoltenberg

Department of Psychology: Faculty Publications

Feminist scholars have called for gender researchers to consider gene-environment interactions for gender-imbalanced disorders (Salk and Hyde Psychology of Women Quarterly, 36, 395–411, 2012). Responding to these calls, the present study integrates objectification theory (Fredrickson and Roberts Psychology of Women Quarterly, 21, 173–206, 1997) and genetic research. In the tested model, objectification experiences are associated with disordered eating through body surveillance and body shame, and serotonin transporter (SLC6A4) genotypes (5-HTTLPR and rs25531), serotonin 2A receptor SNP genotypes (HTR2A rs6311), and the epistatic interaction between those genotypes function as moderators. U.S. undergraduate women (n = 526) …

“A Victim/Survivor Needs Agency”: Sexual Assault Survivors’ Perceptions Of University Mandatory Reporting Policies, Kathryn J. Holland, Allison E. Cipriano, T. Zachary Huit

Department of Psychology: Faculty Publications

In institutions of higher education, mandatory reporting policies require certain employees to report students’ sexual assault disclosures to university officials, even if the student does not want to report. It is commonly assumed that these policies will benefit survivors, but there is a paucity of research to substantiate this assumption. The current study examined college sexual assault survivors’ perceptions of mandatory reporting policies, including three specific policy approaches (Universal, Selective, Student-Directed). Interviews were conducted with 40 college sexual assault survivors and thematic analysis was used to analyze these data. Results found that the mandatory reporting policy approaches that survivors prefer, …

“You Can Catch More Flies With Honey Than Vinegar”: Objectification Valence Interacts With Women’S Enjoyment Of Sexualization To Influence Social Perceptions, Abigail R. Riemer, Jill Allen, Marco Gullickson, Sarah Gervais

Department of Psychology: Faculty Publications

Although objectification is a common experience for women (Fredrickson & Roberts, 1997), little is understood about how women perceive sources of objectifying commentary and behaviors. The current work provides a novel integration of objectification and consistency theories to understand how valence of sexual objectification and women’s feelings about sexual attention interact to predict perceptions of objectifying sources. In two online vignette studies with 121 and 110 U.S. women recruited through MTurk, female participants were asked to recall an experience of complimentary or critical objectification and report perceptions of source warmth, approach behavioral intentions, perceived overlap between the self and the …

An Integrated Relational Framework Of Depressed Mood And Anhedonia During Pregnancy, Rebecca L. Brock, Molly Franz, Erin L. Ramsdell

Department of Psychology: Faculty Publications

Objective: The aim of the present study was to test a unified framework that integrates several theories into a cohesive model to explain the interplay between neuroticism and intimate relationship quality as risk factors for prenatal depression.

Background: There is a notable spike in risk for depression during pregnancy, and the processes unfolding in the interparental relationship during this important time in the family life cycle might serve to mitigate or enhance this risk. Yet there is a need for theory-driven research integrating multiple conceptual frameworks to explicate the role of intimate relationship quality in depression.

Method: In a sample …
