Department of Child, Youth, and Family Studies: Faculty Publications

Despite a robust literature examining the association between sleep problems and cognitive abilities in childhood, little is known about this association in toddlerhood, a period of rapid cognitive development. The present study examined the association between various sleep problems, using actigraphy, and performance on a standardized test of cognitive abilities, longitudinally across three ages (30, 36, and 42 months) in a large sample of toddlers (N = 493). Results revealed a between-subject effect in which the children who had more delayed sleep schedules on average also showed poorer cognitive abilities on average but did not support a within-subjects effect. Results …

Parent Involvement And Its Influence On Children’S Stem Learning: A Review Of The Research, Julie Thomas, Juliana Utley, Soo-Young Hong, Hunkar Korkmaz, Gwen Nugent

Department of Child, Youth, and Family Studies: Faculty Publications

A growing understanding that parents and teachers can effectively collaborate to help children succeed in school has led worldwide policymakers and school leaders to begin deliberate actions to increase parents’ participation in school life. For example, the Chilean Education Minister recently encouraged contracts between parents, schools, and the state to increase parental involvement. The Australian government has formed a Research Alliance for Children and Youth to develop and promote understanding of parent involvement (i.e., what it is, why it matters, how it influences learning) and to build evidence about what works. From a sociological perspective, a school’s organizational boundaries are …


Choosing Quality Early Childhood Curricula, Rachel E. Schachter, Shayne B. Piasta, Laura M. Justice Jan 2020

Choosing Quality Early Childhood Curricula, Rachel E. Schachter, Shayne B. Piasta, Laura M. Justice

Department of Child, Youth, and Family Studies: Faculty Publications

This article summarizes a study investigating the curricula and features of those curricula used by 497 early childhood educators across one Midwestern state. Curricula were identified and coded for quality features derived from the research, theory, and policy literatures. Results indicated that most educators utilized Creative Curriculum or High Scope (over 60%); however, these and many other curricula did not include all the key quality features. Importantly, most educators were utilizing curricula with no evidence of effectiveness for supporting children’s outcomes. Furthermore, limitations in the presence of key curricula features may indicate that curricula generally are not adequately supporting early …


An Investigation Into The Curricula (Type And Quality) Used By Early Childhood Educators, Rachel E. Schachter, Shayne B. Piasta, Laura M. Justice Jan 2020

An Investigation Into The Curricula (Type And Quality) Used By Early Childhood Educators, Rachel E. Schachter, Shayne B. Piasta, Laura M. Justice

Department of Child, Youth, and Family Studies: Faculty Publications

Most preschool-aged children spend time in Head Start and other center-based care. Thus, early educators’ use of a quality curriculum is essential to maximizing children’s learning. We examined the curricula utilized by educators working in diverse settings with children ages 3 to 5, focusing on key features of quality curriculum identified from the literature. Most educators (75%) reported using formal curricula. Creative Curriculum and HighScope were the most common; 6% of educators reported no curriculum use. There was a lack of consensus regarding what constitutes curriculum with 16% of participants reporting the use of materials generally not considered curriculum (e.g., …

Developing A Brief Behavior Rating Scale For Progress Monitoring Of Depression In School Settings, Evan H. Dart, Prerna G. Arora, Tai Collins, Kevin Stark, Clayton R. Cook, Mylien T. Duong, Carolyn A. Mccarty, Beth Doll

Department of Educational Psychology: Faculty Publications

Frequent formative assessment of students’ functioning, or progress monitoring, is a critical component of multi-tiered systems of support as data inform data-driven decisions about response to treatment. Progress monitoring tools for students’ academic and behavioral functioning are readily available and widely researched; however, despite the documented prevalence of depressive disorders among youth and that schools have been put forth as an ideal location for the delivery of mental health services, there are currently no progress monitoring tools to examine students’ response to interventions that target depression. To address this gap, this study sought to develop a progress monitoring assessment of …


Mothers’ And Fathers’ Self-Regulation Capacity, Dysfunctional Attributions And Hostile Parenting During Early Adolescence: A Process-Oriented Approach, Melissa L. Sturge-Apple, Zhi Li, Meredith Martin, Hannah R. Jones-Gordils, Patrick T. Davies Jan 2020

Mothers’ And Fathers’ Self-Regulation Capacity, Dysfunctional Attributions And Hostile Parenting During Early Adolescence: A Process-Oriented Approach, Melissa L. Sturge-Apple, Zhi Li, Meredith Martin, Hannah R. Jones-Gordils, Patrick T. Davies

Department of Educational Psychology: Faculty Publications

The parent-child relationship undergoes substantial reorganization over the transition to adolescence. Navigating this change is a challenge for parents because teens desire more behavioral autonomy as well as input in decision-making processes. Although it has been demonstrated that changes in parental socialization approaches facilitates adolescent adjustment, very little work has been devoted to understanding the underlying mechanisms supporting parents’ abilities to adjust caregiving during this period. Guided by self-regulation models of parenting, the present study examined how parental physiological and cognitive regulatory capacities were associated with hostile and insensitive parent conflict behavior over time. From a process-oriented perspective, we tested …

The Impact Of The Covid-19 Pandemic On Marginalized Populations In The United States: A Research Agenda, Neeta Kantamneni Jan 2020

The Impact Of The Covid-19 Pandemic On Marginalized Populations In The United States: A Research Agenda, Neeta Kantamneni

Department of Educational Psychology: Faculty Publications

International and national crises often highlight inequalities in the labor market that disproportionately affect individuals from marginalized backgrounds. The COVID-19 pandemic, and the resulting changes in society due to social distancing measures, has showcased inequities in access to decent work and experiences of discrimination resulting in many of the vulnerable populations in the United States experiencing a much harsher impact on economic and work-related factors. The purpose of this essay is to describe how the COVID-19 pandemic may differentially affect workers of color, individuals from low-income backgrounds, and women in complex ways. First, this essay will discuss disproportionate representation of …


Does The Spiritual Values/Religion Subscale Of The Self-Description Questionnaire Iii Function Differentially Across Heterosexual And Non-Heterosexual Young Adults? A Measurement Invariance Study, Thai Q. Ong, Deborah L. Bandalos, Susan M. Swearer Jan 2020

Does The Spiritual Values/Religion Subscale Of The Self-Description Questionnaire Iii Function Differentially Across Heterosexual And Non-Heterosexual Young Adults? A Measurement Invariance Study, Thai Q. Ong, Deborah L. Bandalos, Susan M. Swearer

Department of Educational Psychology: Faculty Publications

We evaluated the dimensionality and measurement invariance of the Spiritual Values/Religion (SVR) subscale from the Self-Description Questionnaire III across heterosexual and non-heterosexual young adults. We found a one-factor model provided adequate fit to the data for each group, with the SVR items exhibiting configural, metric, and scalar invariance across the two groups. Given that we established measurement invariance, we examined the latent mean difference on the construct and found the heterosexual group reported significantly higher levels of spiritual value/ religion than the non-heterosexual group. Our results provided empirical support for the theorized factor structure of the SVR items and the …


Differential Effects Of Self- Vs. External-Regulation On Learning Approaches, Academic Achievement, And Satisfaction In Undergraduate Students, Jesús De La Fuente, Paul Sander, Douglas Kauffman, Meryem Yılmaz Soylu Jan 2020

Differential Effects Of Self- Vs. External-Regulation On Learning Approaches, Academic Achievement, And Satisfaction In Undergraduate Students, Jesús De La Fuente, Paul Sander, Douglas Kauffman, Meryem Yılmaz Soylu

Department of Educational Psychology: Faculty Publications

The aim of this research was to determine the degree to which undergraduate students’ learning approach, academic achievement and satisfaction were determined by the combination of an intrapersonal factor (self-regulation) and a interpersonal factor (contextual or regulatory teaching). The hypothesis proposed that greater combined regulation (internal and external) would be accompanied by more of a deep approach to learning, more satisfaction and higher achievement, while a lower level of combined regulation would determine a surface approach, less satisfaction and lower achievement. Within an ex post facto design by selection, 1036 university students completed validated questionnaires using an online tool. Several …

“Isn’T Atheism A White Thing?”: Centering The Voices Of Atheists Of Color, Dena M. Abbott, Debra Mollen, Caitlin Mercier, Elyxcus J. Anaya, Victoria A. Rukus

Department of Educational Psychology: Faculty Publications

Despite a general shift toward secularity, very few people of color in the United States identify as atheist. Further, atheists of color are underrepresented in studies of atheists, and the experiences of atheists of color specifically have, to date, not been captured in the extant scholarship. Addressing this gap in the literature, we interviewed 17 self-identified adult atheists of color, predominantly from Christian backgrounds, residing in the United States, using a critical feminist phenomenological approach. Six broad themes emerged from the data: (a) atheist identity development, (b) experiences of discrimination, (c) isolation, (d) violations of cultural expectations, (e) strategic outness, …

Sexuality Training In Counseling Psychology, Debra Mollen, Theo Burnes, Samantha Lee, Dena M. Abbott

Department of Educational Psychology: Faculty Publications

The United States (U.S.) is characterized by some of the poorest sexual health outcomes in the industrialized world, as indicated by the teen and unplanned pregnancy rates, rate of sexually transmitted infections (STIs), and occurrence of sexual dysfunction. Many people seek psychotherapy for sex-related concerns, yet little is known about the specific education psychologists receive during their training regarding sex. Existing research has largely been conducted in Canada and among clinical psychologists. While studies have revealed that few applied psychology graduate programs offer training in sexuality, very little is known about the specific content areas covered by those programs who …

Ideology And Predictive Processing: Coordination, Bias, And Polarization In Socially Constrained Error Minimization, Nathan E. Wheeler, Suraiya Allidina, Elizabeth U. Long, Stephen P. Schneider, Ingrid J. Haas, William A. Cunningham Jan 2020

Ideology And Predictive Processing: Coordination, Bias, And Polarization In Socially Constrained Error Minimization, Nathan E. Wheeler, Suraiya Allidina, Elizabeth U. Long, Stephen P. Schneider, Ingrid J. Haas, William A. Cunningham

Department of Political Science: Faculty Publications

Recent models of cognition suggest that the brain may implement predictive processing, in which top-down expectations constrain incoming sensory data. In this perspective, expectations are updated (error minimization) only if sensory data sufficiently deviate from these expectations (prediction error). Although originally applied to perception, predictive processing is thought to generally characterize cognitive architecture, including the social cognitive processes involved in ideological thinking. Scaling up these simple computational principles to the social sphere outlines a path by which group members may adopt shared ideologies and beliefs to predict behavior and cooperate with each other. Because ideological judgments are of specific interest …


Developing A Computer-Controlled Treat Dispenser For Canine Operant Conditioning, Walker Arce, Jeffrey R. Stevens Jan 2020

Developing A Computer-Controlled Treat Dispenser For Canine Operant Conditioning, Walker Arce, Jeffrey R. Stevens

Jeffrey Stevens Publications

When performing canine operant conditioning studies, the delivery of the reward can be a limiting factor of the study. While there are a few commercially available options for automatically delivering rewards, they generally require manual input, such as using a remote control, in accordance with the experiment script. This means that human reaction times and transmission distances can cause interruptions to the flow of the experiment. The potential for development of non-supervised conditioning studies is limited by this same factor. To remedy this, we retrofitted an off-the-shelf treat dispenser with new electronics that allow it to be remotely controllable as …

Department of Psychology: Faculty Publications

Serotonin 5-HT2A and 5-HT2C 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-HT2A agonist (TCB-2, 0.4 or 4.0 μg/side) or a 5-HT2C 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 …

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 …


Attributions Of Blame In A Hypothetical Child Sexual Abuse Case: Roles Of Behavior Problems And Frequency Of Abuse, Kate Theimer, David J. Hansen Jan 2020

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 …

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 …

Correspondence Between Cytomegalovirus Immunoglobulin-G Levels Measured In Saliva And Serum, Jenna L. Riis, Hedyeh Ahmadi, Olivia Silke, Steve W. Granger, Crystal I. Bryce, Douglas A. Granger

Department of Psychology: Faculty Publications

Human cytomegalovirus (HCMV) infects more than 80% of the global population. While mostly asymptomatic, HCMV infection can be serious among the immunocompromised, and it is implicated in chronic disease pathophysiology in adulthood. Large-scale minimally invasive HCMV screening could advance research and public health efforts to monitor infection prevalence and prevent or mitigate downstream risks associated with infection. We examine the utility of measuring HCMV immunoglobulin-G (IgG) levels in saliva as an index of serum levels. Matched serum and saliva samples from healthy adults (N = 98; 44% female; 51% white) were assayed for HCMV IgG, total salivary protein, and salivary …

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 Jan 2020

“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, …
