Working Memory, Executive Functioning, And Children's Mathematics, R. Bull, K. A. Espy

Developmental Cognitive Neuroscience Laboratory: Faculty Publications

Approximately 3-6% of school-age children are estimated to have mathematics difficulties (Badian, 1983; Gross-Tsur, Manor, & Shalev, 1996; Kosc, 1974, Lewis, Hitch, & Walker, 1994). There are many more children in regular school classrooms who struggle with mathematics but whose performance is not considered sufficiently poor to be classified as meriting a specific disability in mathematics. Specific mathematic learning disability (MLD) is defined in psychiatric and educational venues as a large discrepancy between mathematics ability compared to reading and general intellectual ability, although the size of the discrepancy required varies. To further complicate matters, mathematic difficulties are associated with other …

Measuring The Development Of Executive Control With The Shape School, K. A. Espy, R. B. Bull, J Martin, W. Stroup

Developmental Cognitive Neuroscience Laboratory: Faculty Publications

Although several neurodevelopmental and psychiatric disorders can emerge during the preschool period, there are comparatively few instruments to assess executive control. Evidence for validity of the Shape School (K. A. Espy, 1997) was examined in a sample of 219 typically developing young children. There was good evidence for validity, as Shape School performance variables were interrelated and were associated to other criterion measures considered to measure aspects of executive control. Also suggesting validity, the Shape School variables varied as a function of whether the task demands (a) were executive, (b) required inhibition of a prepotent response or context-controlled selection among …

Phylogenetic Analysis Of Buggy Creek Virus: Evidence For Multiple Clades In The Western Great Plains, United States Of America, Martin Pfeffer, Jerome E. Foster, Eric A. Edwards, Mary Bomberger Brown, Nicholas Komar, Charles R. Brown

United States Public Health Resources

We present the first detailed phylogenetic analysis of Buggy Creek virus (BCRV), a poorly known alphavirus with transmission cycles involving a cimicid swallow bug (Oeciacus vicarius) vector and cliff swallows (Petrochelidon pyrrhonota) and house sparrows (Passer domesticus) as the principal avian hosts. Nucleotide sequences of a 2,075-bp viral envelope glycoprotein-coding region, covering the entire PE2 gene, were determined for 33 BCRV isolates taken from swallow bugs at cliff swallow colonies in Nebraska and Colorado in the summer of 2001 and were compared with the corresponding region of BCRV isolates collected from Oklahoma in the …

Child Physical Abuse And Neglect, David K. Dilillo, Andrea R. Perry, Michelle Fortier

Department of Psychology: Faculty Publications

Although poor and inhumane treatment of children is not a new phenomenon (Doerner & Lab, 1998; Wolfe, 1999), child physical abuse and neglect were not identified as serious social problems until the 1960s, with the publication of Kempe and colleagues’ description of battered-child syndrome (Kempe, Silverman, Steele, Droegemueller, & Silver, 1962). In this influential study, Kempe and colleagues described the clinical manifestation of this syndrome in terms of the deleterious physical consequences maltreated children experienced, ranging from undetected outcomes to those that cause significant physical impairments. Rather than exploring the potential psychological sequelae of maltreated children, Kempe focused on detailing …

Does How I Feel About It Matter? The Role Of Affect In Cognitive And Behavioral Reactions To An Illness Diagnosis, Darnell Schuettler, Marc T. Kiviniemi

Department of Psychology: Faculty Publications

Individuals often have low rates of compliance with treatment recommendations. We examined the role that experienced affect at the time of illness diagnosis might play in influencing thoughts and feelings relating treatment compliance. Participants were randomly assigned to receive a positive, neutral, or negative affect induction after imagining they were diagnosed with kidney cancer. They then reported on thoughts and feelings about the illness and the treatment regimen. Participants also reported interest in additional information about the illness and behavioral intentions for complying with the treatment regimen. Affect significantly influenced interest in information and behavioral intentions. Both effects were mediated …

The Role Of Child Emotional Responsiveness And Maternal Negative Emotion Expression In Children’S Coping Strategy Use, Rebecca Goodvin, Gustavo Carlo, Julia C. Torquati

Department of Psychology: Faculty Publications

This study examined the additive and interactive effects of children’s trait vicarious emotional responsiveness and maternal negative emotion expression on children’s use of coping strategies. Ninety-five children (mean age = 5.87 years) and their mothers and teachers participated in the study. The mothers reported on their own negative emotion expression and the children’s empathic concern and personal distress tendencies. The mothers and teachers reported on the children’s use of avoidant, support-seeking, and aggressive-venting coping strategies. Empathic concern was positively associated with the children’s use of support seeking and negatively associated with the children’s use of aggressive venting, whereas personal distress …

The Effects Of Victim’S Substance Use And Relationship Closeness On Mock Jurors’ Judgments In An Acquaintance Rape Case, Ashley A. Wenger, Brian H. Bornstein

Department of Psychology: Faculty Publications

Previous research has demonstrated that jurors perceive a female victim who is drunk at the time when she is sexually assaulted as less credible and more deserving of such punishment than a sober victim. In this experiment, we investigated the effect of an alleged acquaintance rape victim’s type of substance use and closeness of relationship with the defendant on the judgments of 152 student mock jurors. Participants read a case summary and answered a series of questions about their impressions of the actors and actions involved in the case. Participants perceived a victim who was sober at the time of …

Psychopathology In Young People With Intellectual Disability, Stewart L. Einfeld, Andrea M. Piccinin, Andrew Mackinnon, Scott M. Hofer, John Taffe, Kylie M. Gray, Daniel E. Bontempo, Lesa R. Hoffman, Trevor Parmenter, Bruce J. Tonge

Department of Psychology: Faculty Publications

Context Comorbid severe mental health problems complicating intellectual disability are a common and costly public health problem. Although these problems are known to begin in early childhood, little is known of how they evolve over time or whether they continue into adulthood. Objective To study the course of psychopathology in a representative population of children and adolescents with intellectual disability. Design, Setting, and Participants The participants of the Australian Child to Adult Development Study, an epidemiological cohort of 578 children and adolescents recruited in 1991 from health, education, and family agencies that provided services to children with intellectual disability aged …

The Path To Licensure For Academic Psychologists: How Tough Is The Road?, David Dilillo, Sarah Degue, Lee M. Cohen, Robert D. Morgan

Department of Psychology: Faculty Publications

What obstacles are faced by academic psychologists seeking professional licensure? Data presented here from all U.S. jurisdictions suggests that licensure requirements vary greatly across states and in some areas may be quite diffi cult to fulfill within the context of an academic position. Results of a survey of training directors of clinical and counseling doctoral programs accredited by the American Psychological Association indicated that, although licensure is expected of most faculty, a number of challenges may impede this goal. Programmatic efforts to facilitate licensure of new faculty, as well as implications of our findings, possible remedies, and recommendations to new …

The Use Of Religion In Death Penalty Sentencing Trials, Monica Miller, Brian H. Bornstein

Department of Psychology: Faculty Publications

Both prosecutors and defense attorneys have presented religious appeals and testimony about a defendant’s religious activities in order to influence capital jurors’ sentencing. Courts that have objected to this use of religion fear that religion will improperly influence jurors’ decisions and interfere with their ability to weigh aggravators and mitigators. This study investigated the effects of both prosecution and defense appeals. Prosecution appeals did not affect verdict decisions; however, use of religion by the defense affected both verdicts and the weighing of aggravators and mitigators. These results could be due to differences in perceived sincerity and remorse that are conveyed …

Single Molecule Detection Systems And Methods, John G. K. Williams, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

A micofluidic system is provided that includes a substrate, a first microchannel disposed in the substrate for providing a reactant to a reaction zone, a second microchannel disposed in the substrate, the third microchannel providing fluid communication between the first and second microchannels. The system also typically includes first and second electrodes, positioned at opposite ends of the second microchannel, for providing an electric field within the second microchannel. In operation, when the reactant is in the reaction zone, a reaction product is produced having a net electric charge different from the electric of the reactant.

Genetic Bases Of Executive Control In Preschool Children: Trails-P Performance Is Related To Drd2 Genotype, S. A. Wiebe, M. Y. Chang, J. Huggenvik, T. Jameson, K. A. Espy

Developmental Cognitive Neuroscience Laboratory: Faculty Publications

Several studies link the D2 dopamine receptor (DRD2) with executive control and the ability to adapt behavior to changing contextual contingencies in human adults (Roesch-Ely 2005; Rodriguez-Jimenez 2006) and in animal models (Kruzich 2004). The present study examined relations between DRD2 and executive control in human development. Recently, a version of the Trail-Making Task suitable for preschool children was developed, which does not require knowledge of letters or numbers (TRAILS-P; Espy 2004). The Trail-Making Test is a neuropsychological test sensitive to frontal or executive dysfunction (Reitan 1955) where subjects must connect stimuli on a page in sequence, connecting letters only …

BACKGROUND. The American Cancer Society, Centers for Disease Control and Prevention, National Cancer Institute, and North American Association of Central Cancer Registries collaborate annually to provide U.S. cancer information, this year featuring the first comprehensive compilation of cancer information for U.S. Latinos.

METHODS. Cancer incidence was obtained from 90% of the Hispanic/Latino and 82% of the U.S. populations. Cancer deaths were obtained for the entire U.S. population. Cancer screening, risk factor, incidence, and mortality data were compiled for Latino and non-Latino adults and children (incidence only). Long-term (1975– 2003) and fixed-interval (1995–2003) trends and comparative analyses by disease …

Linking Adolescent Family And Peer Relationships To The Quality Of Young Adult Romantic Relationships: The Mediating Role Of Conflict Tactics, Lisa J. Crockett, Brandy A. Randall

Department of Psychology: Faculty Publications

This study examined the associations between the quality of adolescents’ peer and family relationships and the quality of their young adult romantic relationships. Adolescents (N = 253) completed self-report measures of their family and peer relationships in grades 10–12; 7 years later, they reported on connectedness, discord, and the conflict tactics used by both partners in their current romantic relationships. Family relationship quality in adolescence predicted the levels of connectedness, discord, and specific conflict behaviors youth reported in their adult romantic relationships. The use of discussion to resolve conflict mediated the association between adolescent family relationships and the level of …

Domestic Violence Treatment Response And Recidivism: A Review And Implications For The Study Of Family Violence, Robert M. Sartin, David J. Hansen, Matthew T. Huss

Department of Psychology: Faculty Publications

Although domestic violence is a significant societal problem, which continues to receive public and private sector attention, intervention and treatment programs have proven inconsistent in their success. This paper reviews the published literature on domestic violence treatment efficacy and post-treatment recidivism and explores the related factors. In addition, challenges in the assessment of domestic violence are briefly discussed. Finally, recent developments are discussed along with their potential benefits, and an appeal is made for the need to study domestic violence in the broader context of family violence.

Retrospective Assessment Of Childhood Sexual And Physical Abuse: A Comparison Of Scaled And Behaviorally Specific Approaches, David Dilillo, Michelle A. Fortier, Sarah A. Hayes, Emily Trask, Andrea R. Perry, Terri Messman-Moore, Angèle Fauchier, Cindy Nash

Department of Psychology: Faculty Publications

This study compared retrospective reports of childhood sexual and physical abuse as assessed by two measures: the Childhood Trauma Questionnaire (CTQ), which uses a Likert-type scaling approach, and the Computer Assisted Maltreatment Inventory (CAMI), which employs a behaviorally specific means of assessment. Participants included 1,195 undergraduate students recruited from three geographically diverse universities. Agreement was high across the two measures in the classification of victim status (92% and 80% for sexual and physical abuse, respectively). However, the CTQ classified more participants as sexually abused than did the CAMI, whereas the opposite trend was found for physical abuse. For child physical …

Decision-Making About Volitional Impairment In Sexually Violent Predators, Cynthia Calkins Mercado, Brian H. Bornstein, Robert F. Schopp

Department of Psychology: Faculty Publications

The Kansas v. Hendricks (1997) decision, in which the Supreme Court authorized post-sentence civil commitment for certain sex offenders, appeared to be constitutionally legitimized by limiting the class of offenders eligible for this special form of civil commitment to those who are “unable to control” their dangerousness. Nowhere in the available record, however, did the Court elucidate what they meant by this notion of volitional impairment. This study sought to examine factors that legal professionals (n = 43), psychologists (n = 40), and mock jurors (n = 76) deem most relevant to a determination of sex offender volitional impairment. Participants, …

The Environment Of Child Maltreatment: Contextual Factors And The Development Of Psychopathology, Debra B. Hecht, David J. Hansen

Department of Psychology: Faculty Publications

Some professionals have hypothesized that the observed problems in children who have been maltreated may actually be a result of the combination of risk factors surrounding the child, including but not limited to direct results of the abuse itself. This article examines the complexity of hypothesized pathways to poor adjustment after physical and sexual abuse. The literature on the impact of major risk factors associated with maltreatment is reviewed in an attempt to clarify the potential contributions of these contextual variables on the development of psychopathology in physically and sexually abused children. The implications this analysis may yield for prevention, …

Participant Responses To Retrospective Surveys Of Child Maltreatment: Does Mode Of Assessment Matter? , David Dilillo, Sarah Degue, Amanda Kras, Andrea R. Di Loreto-Colgan, Cindy Nash

Department of Psychology: Faculty Publications

This study examines the impact that different methods of assessing child maltreatment history may have on adult participants. A total of 334 female undergraduate students were randomly assigned to complete a retrospective measure of child sexual and physical abuse in one of three conditions: paper-and-pencil questionnaire, face-to-face interview, or computer-administered survey. Disclosure rates of abuse, psychological distress and mood change, preferences for assessment format, and perceptions of confi dentiality were examined across the three assessment formats. Although disclosure did not vary by condition, participants with a history of abuse reported more distress and mood change than did nonvictims, particularly in …

Effect Of Nicotine On Negative Affect Among More Impulsive Smokers, Neal Doran, Dennis E. Mcchargue, Bonnie Springs, Joe Vanderveen, Jessica Werth Cook, Malia Richmond

Department of Psychology: Faculty Publications

In the present study, the authors tested the hypothesis that nicotine would provide greater relief from negative affect for more impulsive smokers than for less impulsive smokers. Euthymic adult smokers (N = 70) participated in 2 laboratory sessions, during which they underwent a negative mood induction (music x autobiographical memory), then smoked either a nicotinized or de-nicotinized cigarette. Mixed-effects regression yielded a significant Impulsivity x Condition (nicotinized vs. de-nicotinized) x Time interaction. Simple effects analyses showed that heightened impulsivity predicted greater negative affect relief after smoking a nicotinized cigarette but not after smoking a de-nicotinized cigarette. These data suggest …

Adolescent Perceptions Of Appropriate Parental Reactions In Moral And Conventional Social Domains, Laura M. Padilla-Walker, Gustavo Carlo

Department of Psychology: Faculty Publications

Research suggests that adolescents’ ratings of the appropriateness of parental reactions are influenced by several constructs, including adolescents’ perceptions of the type of parental reaction, the emotions felt by the adolescent and parental intentions. However, little is known regarding how these constructs are differentially predictive of appropriateness in different socialization contexts. One hundred and twenty-two adolescents (mean age = 16.87 years) answered questions regarding past situations in antisocial and prosocial contexts, and in moral and conventional domains. Different parental reactions were reported across moral and conventional domains. In addition, the appropriateness of parental responses varied across domain. Namely, in antisocial …

Using Initiative To Achieve Autonomy: A Model For Advanced Practice In Medical Nutrition Therapy, Annalynn Skipper, Nancy M. Lewis

Department of Nutrition and Health Sciences: Faculty Publications

The purpose of this research was to generate a model of advanced medical nutrition therapy (MNT) practice based on descriptions of their clinical activities provided by advanced- level MNT practitioners. A qualitative approach using grounded theory methodology was employed. The model of advanced MNT practice was based on interviews with 21 credentialed advanced practice registered dietitians from across the United States and Canada. Verbatim transcripts of the interviews were coded for aggregation into themes and subthemes. The resulting model included a single overarching theme: using initiative to achieve autonomy. The five subthemes are aptitude, attitude, expertise, context, and approach. The …

Agricultural Pesticide Use And Risk Of T(14;18)-Defined Subtypes Of Non-Hodgkin Lymphoma, Brian C.-H. Chiu, Bhavana J. Dave, Aaron Blair, Susan M. Gapstur, Shelia Hoar Zahm, Dennis D. Weisenburger

United States Public Health Resources

Pesticides have been specifically associated with the t(14;18)(q32;q21) chromosomal translocation. To investigate whether the association between pesticides and risk of non-Hodgkin lymphoma (NHL) differs for molecular subtypes of NHL defined by t(14; 18) status, we obtained 175 tumor blocks from case subjects in a population-based case-control study conducted in Nebraska between 1983 and 1986. The t(14;18) was determined by interphase fluorescence in situ hybridization in 172 of 175 tumor blocks. We compared exposures to insecticides, herbicides, fungicides, and fumigants in 65 t(14;18)-positive and 107 t(14;18)-negative case subjects with those among 1432 control subjects. Multivariate polytomous logistic regression was used to …

Elevated Positive Mood: A Mixed Blessing For Abstinence, Neal Doran, Bonnie Spring, Belinda Borrelli, Dennis E. Mcchargue, Brian Hitsman, Raymond Niaura, Donald Hedecker

Department of Psychology: Faculty Publications

The present study, a secondary analysis of published data (B. Hitsman et al., 1999), assessed (a) the influence of initial positive mood (PM) on smoking cessation and (b) whether smokers low in PM benefited from fluoxetine versus placebo for cessation. Euthymic adult smokers (N = 103) received 10 weeks of cessation treatment. Analyses showed a Time x PM interaction, indicating that higher baseline PM predicted decreased abstinence during treatment but increased abstinence afterward, mediated by time to dropout. Dichotomous initial PM interacted with drug, suggesting a benefit of fluoxetine for low-PM smokers. Results indicate that lower pretreatment PM may …

Mean Length Of Utterance In Children With Specific Language Impairment And In Younger Control Children Shows Concurrent Validity And Stable And Parallel Growth Trajectories, Mabel L. Rice, Sean M. Redmond, Lesa Hoffman

Department of Psychology: Faculty Publications

Purpose: Although mean length of utterance (MLU) is a useful benchmark in studies of children with specific language impairment (SLI), some empirical and interpretive issues are unresolved. The authors report on 2 studies examining, respectively, the concurrent validity and temporal stability of MLU equivalency between children with SLI and typically developing children. Method: Study 1 used 124 archival conversational samples consisting of 39 children with SLI (age 5;0 [years;months]), 40 MLU-equivalent typically developing children (age 3;0), and 45 age-equivalent controls. Concurrent validity of MLU matches was examined by considering the correspondence between MLU and developmental sentence scoring (DSS), …

Validity And Reliability Of A Quantitative Food Frequency Questionnaire Measuring N-3 Fatty Acid Intakes In Cardiac Patients In The Midwest: A Validation Pilot Study, Paula K. Ritter-Gooder, Nancy M. Lewis, Kimberly B. Heidal, Kent M. Eskridge

Department of Nutrition and Health Sciences: Faculty Publications

The purpose of this pilot study was to test the validity and reliability of a quantitative n-3 fatty acid food frequency questionnaire (FFQ) for later use with larger groups of individuals. A convenience sample of heart patients provided dietary data via three 24-hour food recalls and FFQs. Participants were women (n = 17) and men (n = 11), 43 to 77 years of age. The association of mean daily intake of n-3 fatty acids obtained using food recalls and the FFQ was assessed by Pearson correlation. The reliability of the FFQ was assessed using coefficient α. Correlation of n-3 fatty …

Characteristics Of Staff–Patient Interactions On A Behavioral Treatment Unit For Patients With Serious Mental Illness, And The Effects Of A Behavior Management Training Program On Staff Performance, Lindsay S. Schenkel

Department of Psychology: Dissertations, Theses, and Student Research

Despite the existence of effective psychological interventions for people diagnosed with schizophrenia, these continue to be underutilized. This problem is most critical in the case of so called “treatment-refractory” patients, where, paradoxically, effective interventions with among the strongest evidence base in psychiatry exist – namely – inpatient social-learning-based rehabilitation programs. Barriers to implementation and effective maintenance of such programs include a low frequency of staff-patient interactions and a relatively high frequency of non-therapeutic staff behaviors, lack of staff training and background in behavioral treatment, negative attitudes towards behavioral interventions, and tension between professional disciplines. This study examined the nature and …

Early Predictors Of Self-Regulation In Middle Childhood, Rebecca A. Colman, Sam A. Hardy, Myesha Albert, Marcela Raffaelli, Lisa J. Crockett

Department of Psychology: Faculty Publications

The present study examined the contribution of caregiving practices at ages 4–5 (Time 1) to children’s capacity for self regulation at ages 8–9 (Time 2). The multiethnic sample comprised 549 children of National Longitudinal Survey of Youth (NLSY) participants. High levels of maternal warmth and low levels of physically punitive discipline at Time 1 were associated with a greater capacity for self-regulation at Time 2. These associations remained significant once initial levels of self-regulation were taken into account, indicating that the development of self-regulation is open to caregiver infl uence during childhood. Neither child gender nor ethnicity moderated the effects …

Disease Risks Associated With Increasing Feral Swine Numbers And Distribution In The United States, Thomas Hutton, Thomas J. Deliberto, Sheldon Owen, Bruce Morrison

Michigan Bovine Tuberculosis Bibliography and Database

Feral hogs or “wild boars” come from several sources and include released or escaped domestic swine and the truly wild European boar. When free-roaming in North America, all are included in the term “feral swine,” as are hybrids of the two types. Although morphologically distinct, both the feral swine and European wild swine are recognized as Sus scrofa. The physical damage caused by feral swine has been well documented and includes damage to vehicles, vineyards, tree plantings, archaeological sites, agricultural crops, turf, soils, rare plant communities, and wildlife habitat (Seward et al. 2004). In addition they compete with livestock …

Evaluation Of Serum Immunoglobulins Among Individuals Living Near Six Superfund Sites, Dhelia M. Williamson, Mary C. White, Charles Poole, David Kleinbaum, Robert Vogt, Kari North

United States Public Health Resources

Residents living in communities near Superfund sites have expressed concern that releases from these facilities affect their health, including adverse effects on their immune systems. We used data from six cross-sectional studies to evaluate whether people who live near several Superfund sites are more likely to have individual immunoglobulin test results (IgA, IgG, and IgM) below or above the reference range than those who live in comparison areas with no Superfund site. Study participants consisted of target-area residents who lived close to a Superfund site and comparison area residents who were not located near any Superfund or hazardous waste sites. …
