Fluid Grouping: Quantifying Group Engagement Around Interactive Tabletop Exhibits In The Wild, Florian Block, James Hammerman, Michael Horn, Amy Spiegel, Jonathan Christiansen, Brenda Phillips, Judy Diamond, E Margret Evans, Chia Shen

Department of Educational Psychology: Faculty Publications

Interactive surfaces are increasingly common in museums and other informal learning environments where they are seen as a medium for promoting social engagement. However, despite their increasing prevalence, we know very little about factors that contribute to collaboration and learning around interactive surfaces. In this paper we present analyses of visitor engagement around several multi-touch tabletop science exhibits. Observations of 629 visitors were collected through two widely used techniques: video study and shadowing. We make four contributions: 1) we present an algorithm for identifying groups within a dynamic flow of visitors through an exhibit hall; 2) we present measures of …

Bugs Are Not Loved, David Bober

Nebraska College Preparatory Academy: Senior Capstone Projects

The story The Metamorphosis is about Gregor, a young salesman, who turns into a giant insect. Over the course of The Metamorphosis, Gregor slowly begins to hate his change more and more. During his change, he slowly separates from his family to the point where they are relieved when he dies. This story is important because the protagonists has clear ordeals with change and how it affects him. From the story, I learned that most change is often resented, and when change is pushed, it usually ends negatively.

Impacts Of Stress On Adolescents, Diana Molina

Nebraska College Preparatory Academy: Senior Capstone Projects

Stress is a state of mental or emotonal strain or tension resultng from adverse or extremely demanding circumstances. Stress is important because it is a problem that everyone will most likely deal with. I researched the causes of stress, the effects that stress has on the body, as well as ways to cope with stress efficiently in adolescents.

Our Dystopian World, Kellee Nguyen

Nebraska College Preparatory Academy: Senior Capstone Projects

If we do not heed the warnings in Margaret Atwood’s dystopian novel the Handmaid’s Tale, we, similar to handmaids will lose ourselves to society’s conveyor belt: go to school, graduate, attend college, graduate once more, raise a family, and then work away the rest of our lives. Margaret Atwood’s The Handmaid's Tale acts as an in depth metaphoric replication of modern society. The society in which Offred resides in, through historical events, reasoning, and the decrease in birth rates, the government's action is justified as the people's moral values are suppressed and their rights taken away from them. Likewise, in …

Oprm1 Rs1799971 Genotype Predicts Drinking Behavior In Males, But Not Females, Sarah Hughes Berheim, Carmen Ochoa, Grace Sullivan, Scott F. Stoltenberg

UCARE: Research Products

• The prevalence of alcohol disorders costs Americans $223.5 billion yearly due mostly from losses in workplace productivity, as well as health care and criminal justice expenses (CDC, 2016).

• Maximum number of drinks consumed in a 24 hour period is a valid indicator of dangerous drinking behavior and may reflect an increased tolerance for high levels of alcohol (Edenberg, 2016).

• Awareness of factors related to such heavy drinking is important for targeting interventions for dangerous alcohol use.

• Men drink significantly more than women, with about 4.5% of men and 2.5% of women meeting the diagnostic criteria for …

Double Dissociation Of The Anterior And Posterior Dorsomedial Caudate–Putamen In The Acquisition And Expression Of Associative Learning With The Nicotine Stimulus, Sergios Charntikov

Department of Psychology: Dissertations, Theses, and Student Research

Tobacco use is the leading cause of preventable deaths worldwide. This habit is not only debilitating to individual users but also to those around them (second-hand smoking). Nicotine is the main addictive component of tobacco products and is a moderate stimulant and a mild reinforcer. Importantly, besides its unconditional effects, nicotine also has conditioned stimulus effects that may contribute to the tenacity of the smoking habit. Because the neurobiological substrates underlying these processes are virtually unexplored, the present study investigated functional involvement of dorsomedial caudate putamen (dmCPu) in the conditioning processes with nicotine as a conditioned stimulus. Rats were trained …

An Analytic Study Of The Professional Development Research In Early Childhood Education, Rachel E. Schachter

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

The goal of this study was to examine empirical research on the design, delivery, and measurement of the effects of professional development (PD) for early childhood educators in order to provide insight into what the field has accomplished as well as suggest directions for future PD programs and research. Through the use of rigorous inclusion criteria outlined by S. M. Wilson, R. E. Floden, and J. Ferrini-Mundy (2001), 73 studies were included and analyzed. On average, 25% (M = 12.68, SD = 9.99) of references in each study were specifically about PD. The majority of studies (n = …

Stress And Eyewitness Memory: Timing Of Stressor And Association With Cortisol Stress Responding, Timothy Ryan Robicheaux

Department of Psychology: Dissertations, Theses, and Student Research

Witnesses to and victims of criminal events can face significant stress during such encounters. Stress responding consists of a multitude of responses (e.g., anxiety, cardiovascular changes, cortisol responding). In the current study, I utilized a physiological stressor (i.e., the cold-pressor test) and a facial recognition paradigm to examine the relationship between cortisol change following stress exposure and memory accuracy. More specifically, I examined whether cortisol levels at specific memory stages (i.e., acquisition and retrieval) predicted stress responding differently.

Findings suggested that individual differences in cortisol stress responding to the cold-pressor test predicted facial recognition when peak cortisol was at a …

Parenting Young Children In Contemporary Chinese Society: A Mixed Methods Study, Lixin Ren

Department of Psychology: Dissertations, Theses, and Student Research

The purpose of this mixed methods study was to examine contemporary Chinese parents’ childrearing expectations, goals, and practices for their preschool-aged children. Participants included 154 parents with preschool-aged children (children’s mean age was 52.48 months with a standard deviation of 6.84) and 27 teachers recruited from seven preschools located in three small cities in northeastern China. In the quantitative phase, parents completed questionnaires measuring parental expectations (social-emotional and academic expectations), parenting styles, child social competence, and child pre-academic performance. The head teacher of each target child reported the child’s social competence and pre-academic performance. It was hypothesized that parental expectations …

How People Evaluate Others With Social Anxiety Disorder: A Comparison To Depression And General Mental Illness Stigma, Kristen N. Anderson, Andrew B. Jeon, Jordan A. Blenner, Richard L. Wiener, Debra A. Hope

Department of Psychology: Faculty Publications

Despite the availability of effective interventions, most individuals with social anxiety disorder do not seek treatment. Given their fear of negative evaluation, socially anxious individuals might be especially susceptible to stigma concerns, a recognized barrier for mental health treatment. However, very little is known about the stigma specific to social anxiety disorder. In a design similar to Feldman and Crandall (2007), university undergraduate students read vignettes about target individuals with a generic mental illness label, major depressive disorder, and social anxiety disorder. Subjects rated each of 3 people in the vignettes on social distance and 17 dimensions including dangerousness, heritability …

Civility And Academic Freedom After Salaita, David Moshman, Frank Edler

Department of Psychology: Faculty Publications

The 2014 unhiring of Professor Steven Salaita by the University of Illinois raises at least three distinct issues: (1) the right of faculty to speak out in public on matters of public concern; (2) the academic freedom of academic departments to make academic decisions; and (3) the role of civility in education. After differentiating the third issue from the first two, we extend the discussion to other recent cases involving civility in education. The cases range from overt coercion to implicit threats and subtle pressures. We explain that uncivil speech is generally protected by the First Amendment but that this …

Diverse Perspectives Of Parents, Diverse Concepts Of Parent Involvement And Participation: What Can They Suggest To Researchers?, Carolyn P. Edwards, Traci Shizu Kutaka

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

Diversity of experiences and perspectives, it is widely agreed, should be a source of strength in home-school partnerships, as in other aspects of educational endeavor. Yet often, in the literature, diversity is presented as a complication to be overcome. A limiting mindset often prevails, both in theory and practice, where diversity is regarded as an issue or barrier, even amidst the best of intentions to be inclusive. In this chapter, we argue that this limiting mindset on diversity may in fact derive in part from the conceptual frameworks with which we in the United States contemplate and conduct research on …

Repeated Effects Of The Neurotensin Receptor Agonist Pd149163 In Three Animal Tests Of Antipsychotic Activity: Assessing For Tolerance And Cross-Tolerance To Clozapine, Shinnyi Chou, Collin Davis, Sean Jones, Ming Li

Department of Psychology: Faculty Publications

Neurotensin is an endogenous neuropeptide closely associated with the mesolimbic dopaminergic system and shown to possess antipsychotic-like effects. In particular, acute neurotensin receptor activation can inhibit conditioned avoidance response (CAR), attenuate phencyclidine (PCP)-induced prepulse inhibition (PPI) disruptions, and reverse PCP-induced hyperlocomotion. However, few studies have examined the long term effects of repeated neurotensin receptor activation and results are inconsistent. Since clinical administration of antipsychotic therapy often requires a prolonged treatment schedule, here we assessed the effects of repeated activation of neurotensin receptors using an NTS1 receptor selective agonist, PD149163, in 3 behavioral tests of antipsychotic activity. We also investigated whether …

Perception Of Time Since Smoking Cessation: Time In Memory Can Elapse Faster, Julia N. Soulakova, Brianna C. Bright, Lisa J. Crockett

Department of Psychology: Faculty Publications

Self-reports concerning smoking behaviors are subject to different types of response bias that may severely affect the data quality. This study examined the evidence and extent of backward telescoping bias in reports on time since completely quitting smoking among former smokers. The study goals were to determine whether the extent of bias differs, on average, across subpopulations with diverse sociodemographic characteristics, prior smoking habits and duration of smoking abstinence, and across the survey administration mode (phone, in-person, mixed). The sample included 1,611 subjects who responded to the 2002–2003 Tobacco Use Supplement to the Current Population Survey. Multiple regressions for subjects …

Challenging The Political Assumption That “Guns Don’T Kill People, Crazy People Kill People!”, Heath J. Hodges, Mario Scalora

Department of Psychology: Faculty Publications

Every time an infamous mass shooting takes place, a storm of rhetoric sweeps across this country with the fury of a wild fire. “Why are we letting these people carry guns?” “Why were they not hospitalized?” “The government needs to crack down on this issue!” What is the government’s response to these cries of concern? Politicians and the media attempt to ease public fears by drawing tenuous connections among a handful of poorly understood tragedies. The salient commonality is that these high-profile shooters had some history of mental illness. A cursory review of the Internet will paint a troubling picture …

Does Drinking To Cope Explain Links Between Emotion-Driven Impulse Control Difficulties And Hazardous Drinking? A Longitudinal Test, Laura E. Watkins, Molly R. Franz, David Dilillo, Kim L. Gratz, Terri L. Messman-Moore

Department of Psychology: Faculty Publications

Difficulty controlling impulsive behaviors when experiencing negative emotions is a prominent risk factor for hazardous alcohol use, and prior research suggests that drinking to cope may mediate this association. The present study examines this possibility prospectively in a sample of 490 young adult women between the ages of 18 and 25. Participants completed measures of emotion-driven impulse control difficulties, drinking to cope, and hazardous alcohol use at six time points over the course of approximately 20 months (i.e., one assessment every four months). Multilevel structural equation modeling revealed that drinking to cope fully mediated the relationship between emotion-driven impulse control …

Biomechanics Of Head Impacts Associated With Diagnosed Concussion In Female Collegiate Ice Hockey Players, Bethany J. Wilcox, Jonathan G. Beckwith, Richard M. Greenwald, Neha P. Raukar, Jeffrey J. Chu, Thomas W. Mcallister, Laura A. Flashman, Arthur C. Maerlender, Ann-Christine Duhaime,, Joseph J. Crisco

Department of Psychology: Faculty Publications

Epidemiological evidence suggests that female athletes may be at a greater risk of concussion than their male counterparts. The purpose of this study was to examine the biomechanics of head impacts associated with diagnosed concussions in a cohort of female collegiate ice hockey players. Instrumented helmets were worn by 58 female ice hockey players from 2 NCAA programs over a three year period. Kinematic measures of single impacts associated with diagnosed concussion and head impact exposure on days with and without diagnosed concussion were evaluated. Nine concussions were diagnosed. Head impact exposure was greater in frequency and magnitude on days …

Programmed Physical Exertion In Recovery From Sports-Related Concussion: A Randomized Pilot Study, Arthur C. Maerlender, Wanda Rieman, Jonathan Lichtenstein, C. Condiracci

Department of Psychology: Faculty Publications

Although no data exist, general practice recommends only rest following concussion. This randomized clinical trial found that programmed physical exertion during recovery produced no significant differences in recovery time between groups of participants. However, high levels of exertion were deleterious. This study provides initial evidence that moderate physical activity is a safe replacement behavior during recovery.

Mexican-Origin Parents’ Work Conditions And Adolescents’ Adjustment, Lorey A. Wheeler, Kimberly A. Updegraff, Ann Crouter

Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications

Mexican-origin parents’ work experiences are a distal extra-familial context for adolescents’ adjustment. This two-wave multi-informant study examined the prospective mechanisms linking parents’ work conditions (i.e., self-direction, work pressure, workplace discrimination) to adolescents’ adjustment (i.e., educational expectations, depressive symptoms, risky behavior) across the transition to high school drawing on work socialization and spillover models. We examined the indirect effects of parental work conditions on adolescent adjustment through parents’ psychological functioning (i.e., depressive symptoms, role overload) and aspects of the parent-adolescent relationship (i.e., parental solicitation, parent-adolescent conflict), as well as moderation by adolescent gender. Participants were 246 predominantly immigrant, Mexican-origin, two-parent families …

Strategies To Support Parent Engagement During Home Visits In Early Head Start And Head Start, Lisa Knoche, Christine Marvin, Susan M. Sheridan

Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications

This study explores strategies used by early childhood professionals (ECPs) involved in a school readiness intervention to support parent engagement in young children’s learning. Thirty-two ECPs were recorded during home visits with young children and their families who were enrolled in Early Head Start and Head Start programming. Frequency of strategy use is reported, and strategy use is significantly correlated with rates of parent-ECP interactions during visits but not to parent-child interaction rates nor with overall quality ratings of parent-child engagement. ECPs’ overall success in promoting parent engagement was positively and significantly correlated with ECPs’ efforts to elicit parent observations …

Broadening Campus Threat Assessment Beyond Mass Shootings, Brandon A. Hollister, Mario Scalora

Department of Psychology: Faculty Publications

Record reviews of public figure, primary/secondary school, and workplace threateners and attackers displayed the importance of noticing pre-incident behaviors and intervening to prevent violence. General crime prevention strategies did not appear applicable. Similarly, campus threat assessment research has considered targeted violence as distinctive and unable to be reviewed within general collegiate samples, which has related to questions about the prevalence, predictiveness, applicability, and reporting of pre-incident behaviors. This article applies general criminological and crime prevention findings to these questions and presents campus threat assessment methodologies informed by these fields. With college student surveys, pre-incident behaviors have appeared predictive of general …

Behavior-Associated And Post-Consumption Glucose Entry Into The Nucleus Accumbens Extracellular Space During Glucose Free-Drinking In Trained Rats, Ken T. Wakabayashi, Eugene A. Kiyatkin

Department of Psychology: Faculty Publications

Glucose is the primary energetic substrate for the metabolic activity of brain cells and its proper delivery from the arterial blood is essential for neural activity and normal brain functions. Glucose is also a unique natural reinforcer, supporting glucose-drinking behavior without food or water deprivation. While it is known that glucose enters brain tissue via gradient-dependent facilitated diffusion, it remains unclear how glucose levels are changed during natural behavior and whether the direct central action of ingested glucose can be involved in regulating glucose-drinking behavior. Here, we used glucose biosensors with high-speed amperometry to examine the pattern of phasic and …

Relations Between Toddler Sleep Characteristics, Sleep Problems, And Temperament, Victoria J. Molfese, Kathleen Moritz Rudasill, Amanda Prokasky, Carly Champagne, Molly Holmes, Dennis L. Molfese, Jack Bates

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

Two sources of information (parent reported sleep diaries and actigraph records) were used to investigate how toddler sleep characteristics (bed time/sleep onset, wake time/sleep offset, total nighttime sleep and total sleep time) are related to sleep problems and temperament. There were 64 toddler participants in the study. Consistent with studies of older children, parent reports differed from actigraph based records. The findings that parent reported and actigraph recorded sleep characteristics varied as a function of parent report of toddler sleep problems and temperament add needed information on toddler sleep. Such information may contribute to improving parents’ awareness of their child’s …

Examining The Validity Of The Homework Performance Questionnaire: Multi-Informant Assessment In Elementary And Middle School, Thomas J. Power, Marley W. Watkins, Jennifer A. Mautone, Christy M. Walcott, Michael J. Coutts, Susan M. Sheridan

Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications

Methods for measuring homework performance have been limited primarily to parent reports of homework deficits. The Homework Performance Questionnaire (HPQ) was developed to assess the homework functioning of students in Grades 1 to 8 from the perspective of both teachers and parents. The purpose of this study was to examine the factorial validity of teacher and parent versions of this scale, and to evaluate gender and grade-level differences in factor scores. The HPQ was administered in 4 states from varying regions of the United States. The validation sample consisted of students (n=511) for whom both parent and teacher ratings were …

Parent Engagement During Home Visits In Early Head Start And Head Start: Useful Strategies For Practitioners, Lisa Knoche, Christine Marvin, Susan M. Sheridan

Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications

This study explores strategies used by early childhood professionals (ECPs) involved in a school readiness intervention to support parent engagement in young children’s learning. In this study, we used video recordings to understand the ECP-parent interactions during Early Head Start and Head Start home visits. We coded the videos for the number of parent engagement strategies that were used by ECPs as well as the quality of parent engagement during visits, including the amount of parent-child interaction that took place during the visits. Findings have implications for the implementation of the Head Start Parent, Family and Community Engagement (PFCE) Framework, …

Equate: Observed-Score Linking And Equating In R, Anthony D. Albano

Department of Educational Psychology: Faculty Publications

Linking and equating are statistical procedures used to convert scores from one measurement scale to another. These procedures are most often used in testing programs that involve multiple test forms, where adjustments are made for form difficulty differences when creating a measurement scale that is common across forms. Linking and equating methods are traditionally distinguished by the type of scores they are applied to, whether observed scores or scores from an item response theory model. Methods are also distinguished by the study design under which measurements are taken. The R package equate (Albano, 2014) is free, open-source software for conducting …

Building An Adaptive Brain Across Development: Targets For Neurorehabilitation Must Begin In Infancy, Jamie O. Edgin, Caron A. C. Clark, Esha Massand, Annette Karmiloff-Smith

Department of Educational Psychology: Faculty Publications

Much progress has been made toward behavioral and pharmacological intervention in intellectual disability, which was once thought too difficult to treat. Down syndrome (DS) research has shown rapid advances, and clinical trials are currently underway, with more on the horizon. Here, we review the literature on the emergent profile of cognitive development in DS, emphasizing that treatment approaches must consider how some “end state” impairments, such as language deficits, may develop from early alterations in neural systems beginning in infancy. Specifically, we highlight evidence suggesting that there are pre- and early postnatal alterations in brain structure and function in DS, …

Neural Responses To Truth Telling And Risk Propensity Under Asymmetric Information, Hideo Suzuki, Masaya Misaki, Frank Krueger, Jerzy Bodurka

Department of Educational Psychology: Faculty Publications

Trust is multi-dimensional because it can be characterized by subjective trust, trust antecedent, and behavioral trust. Previous research has investigated functional brain responses to subjective trust (e.g., a judgment of trustworthiness) or behavioral trust (e.g., decisions to trust) in perfect information, where all relevant information is available to all participants. In contrast, we conducted a novel examination of the patterns of functional brain activity to a trust antecedent, specifically truth telling, in asymmetric information, where one individual has more information than others, with the effect of varying risk propensity. We used functional magnetic resonance imaging (fMRI) and recruited 13 adults, …

Mexican-American Adolescents’ Gender-Typed Characteristics: The Role Of Sibling And Friend Characteristics, Norma J. Perez-Brena, Lorey A. Wheeler, Kimberly A. Updegraff, David R. Shaefer

Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications

This study examined the role of sibling and friend characteristics in Mexican-American youth’s gender-typed characteristics (i.e., attitudes, interests, and leisure activities) in early versus middle adolescence using a sibling design. Mexican-American 7th graders (M = 12.51 years; SD = .58) and their older siblings (M = 15.48 years; SD = 1.57) from 246 families participated in home interviews and a series of seven nightly phone calls. Results revealed that younger/early adolescent siblings reported more traditional gender role attitudes than their older/middle adolescent siblings and older brothers were more traditional in their attitudes than older sisters. When comparing siblings’ …

The Influence Of A Juvenile’S Abuse History On Support For Sex Offender Registration, Margaret C. Stevenson, Cynthia J. Najdowski, Jessica M. Salerno, Tisha R.A. Wiley, Bette L. Bottoms, Katlyn S. Farnum

Department of Psychology: Faculty Publications

We investigated whether and how a juvenile’s history of experiencing sexual abuse affects public perceptions of juvenile sex offenders in a series of 5 studies. When asked about juvenile sex offenders in an abstract manner (Studies 1 and 2), the more participants (community members and undergraduates) believed that a history of being sexually abused as a child causes later sexually abusive behavior, the less likely they were to support sex offender registration for juveniles. Yet when participants considered specific sexual offenses, a juvenile’s history of sexual abuse was not considered to be a mitigating factor. This was true when participants …
