Confirmatory Factor Analysis Of The Behavior Rating Inventory Of Executive Function (Brief) In A Clinical Sample, G. G. Gioia, P. K. Isquith, P. D. Retzlaff, K. A. Espy Nov 2002

Confirmatory Factor Analysis Of The Behavior Rating Inventory Of Executive Function (Brief) In A Clinical Sample, G. G. Gioia, P. K. Isquith, P. D. Retzlaff, K. A. Espy

Developmental Cognitive Neuroscience Laboratory: Faculty and Staff Publications

Evidence for the validity of the Behavior Rating Inventory of Executive Function (BRIEF; Gioia, Isquith, Guy, & Kenworthy, 2000) based on internal structure was examined in a sample of children with mixed clinical diagnoses via maximum likelihood confirmatory factor analysis. Four alternative factor models of children's executive function, based on current theories that posit a unidimensional versus fractionated model (Rabbitt, 1997; Shallice & Burgess, 1991), using the revised 9-scale BRIEF configuration that separates two components of the Monitor scale, were examined for model fit. A 3-factor structure best modeled the data when compared directly with 1-, 2-, and 4-factor models. …

Executive Functions In Preschool Children Born Preterm: Application Of Cognitive Neuroscience Paradigms, K. A. Espy, M. M. Stalets, M. D. Mcdiarmid, T. E. Senn, M. F. Cwik, A. Hamby Nov 2002

Executive Functions In Preschool Children Born Preterm: Application Of Cognitive Neuroscience Paradigms, K. A. Espy, M. M. Stalets, M. D. Mcdiarmid, T. E. Senn, M. F. Cwik, A. Hamby

Developmental Cognitive Neuroscience Laboratory: Faculty and Staff Publications

Although children born preterm are at risk for neuropsychological impairments at school age and adolescence, including difficulties with visual motor integration, spatial/constructional skills, attention, arithmetic, and nonverbal executive functions, specific neuropsychological outcome has not been investigated adequately in preschoolers. Application of cognitive neuroscience tasks offers the opportunity to characterize early executive functions in young children born preterm. In a preliminary sample of 29 preschool children born preterm (M birth gestational age=32.4 weeks), executive function outcome was compared to that of fullterm controls by contrasting performance on two prototypic delayed-response-type paradigms, Delayed Alternation and Spatial Reversal. Preschoolers born preterm correctly retrieved …

Individual Differences In The Development Of Executive Function In Children: Lessons From The Delayed Response And A-Not-B Tasks, K. A. Espy, P. M. Kaufmann Nov 2002

Individual Differences In The Development Of Executive Function In Children: Lessons From The Delayed Response And A-Not-B Tasks, K. A. Espy, P. M. Kaufmann

Developmental Cognitive Neuroscience Laboratory: Faculty and Staff Publications

An explosion of research activity in the area of attention, memory, and executive function has been noted since the mid-1980s (Lyon & Krasnegor, 1996). The bulk of this activity, however, has focused on the examination of group differences in executive skills, with less attention devoted to the manner by which individual children differ in executive skills from their peers. This chapter explores individual differences from a developmental perspective, that is, by returning to the emergence of basic executive functions and tracing the subsequent manifestations by examining the individual patterns of change. Therefore, it first reviews the history of executive function …

What Will My Parents Think? Relations Among Adolescents’ Expected Parental Reactions, Prosocial Moral Reasoning, And Prosocial And Antisocial Behaviors, Jennifer M. Wyatt, Gustavo Carlo Nov 2002

What Will My Parents Think? Relations Among Adolescents’ Expected Parental Reactions, Prosocial Moral Reasoning, And Prosocial And Antisocial Behaviors, Jennifer M. Wyatt, Gustavo Carlo

Department of Psychology: Faculty Publications

Prior researchers confirmed socialization models depicting parenting practices and social cognitions associated with prosocial and antisocial behaviors. However, little research has focused on processes underlying the link between parenting and these behaviors. Per Grusec and Goodnow’s internalization model, children and adolescents develop expectancies regarding their parents’ reactions to their behaviors. Adolescents’ expected parental reactions to prosocial behaviors were hypothesized to predict prosocial behaviors; expectations regarding antisocial behaviors were expected to predict antisocial behaviors. For this study, 80 adolescents and their parents reported adolescents’ antisocial and prosocial behaviors. Adolescents completed a measure of prosocial moral reasoning and an assessment of how …

Adolescent Risk Factors For Sexual Victimization: A Longitudinal Analysis Of Rural Women, Janine M. Zweig, Aline Sayer, Lisa J. Crockett, Judith R. Vicary Nov 2002

Adolescent Risk Factors For Sexual Victimization: A Longitudinal Analysis Of Rural Women, Janine M. Zweig, Aline Sayer, Lisa J. Crockett, Judith R. Vicary

Department of Psychology: Faculty Publications

Longitudinal data were used to examine risk factors for sexual victimization among 237 young adult rural women. In this sample, 8% reported experiencing forced sex (i.e., physically violent experiences) and a separate 22% reported experiencing coerced sex (i.e., external psychological manipulation, substance-related coercion, or internal psychological pressure.) Women who had more educated mothers had a greater probability of reporting forced sex. In addition, mothers’ education moderated the relationship between individual risk factors and the probability of reporting forced sex. For women with less educated mothers, higher frequency of sexual activity during adolescence was related to an increased probability of reporting …

Passive Transfer Of Virus-Specific Antibodies Confers Protection Against Reproductive Failure Induced By A Virulent Strain Of Porcine Reproductive And Respiratory Syndrome Virus And Establishes Sterilizing Immunity, Fernando A. Osorio, J. A. Galeota, E. Nelson, Bruce W. Brodersen, Alan R. Doster, R. Wills, F. Zuckermann, W. W. Laegried Oct 2002

Passive Transfer Of Virus-Specific Antibodies Confers Protection Against Reproductive Failure Induced By A Virulent Strain Of Porcine Reproductive And Respiratory Syndrome Virus And Establishes Sterilizing Immunity, Fernando A. Osorio, J. A. Galeota, E. Nelson, Bruce W. Brodersen, Alan R. Doster, R. Wills, F. Zuckermann, W. W. Laegried

School of Veterinary and Biomedical Sciences: Faculty Publications

Immune mechanisms mediating protective immunity against porcine reproductive and respiratory syndrome virus (PRRSV) are not well understood. The PRRSV-specific humoral immune response has been dismissed as being ineffective and perhaps deleterious for the host. The function of PRRSV antibodies in protective immunity against infection with a highly abortifacient strain of this virus was examined by passive transfer experiments in pregnant swine. All of a group of pregnant gilts (n = 6) that received PRRSV immunoglobulin (Ig) from PRRSV-convalescent, hyperimmune animals were fully protected from reproductive failure as judged by 95% viability of offspring at weaning (15 days of age). …

Mycobacterium Smegmatis L-Alanine Dehydrogenase (Ald) Is Required For Proficient Utilization Of Alanine As A Sole Nitrogen Source And Sustained Anaerobic Growth, Zhengyu Feng, Nancy E. Caceres, Gautam Sarath, Raul G. Barletta Sep 2002

Mycobacterium Smegmatis L-Alanine Dehydrogenase (Ald) Is Required For Proficient Utilization Of Alanine As A Sole Nitrogen Source And Sustained Anaerobic Growth, Zhengyu Feng, Nancy E. Caceres, Gautam Sarath, Raul G. Barletta

School of Veterinary and Biomedical Sciences: Faculty Publications

NAD(H)-dependent L-alanine dehydrogenase (EC 1.4.1.1) (Ald) catalyzes the oxidative deamination of L-alanine and the reductive amination of pyruvate. To assess the physiological role of Ald in Mycobacterium smegmatis, we cloned the ald gene, identified its promoter, determined the protein expression levels, and analyzed the combined effects of nutrient supplementation, oxygen availability, and growth stage on enzyme activity. High Ald activities were observed in cells grown in the presence of L- or D-alanine regardless of the oxygen availability and growth stage. In exponentially growing cells under aerobic conditions, supplementation with alanine resulted in a 25- to 50-fold increase in the …

A Novel Herpes Simplex Virus Type 1 Transcript (Al-Rna) Antisense To The 5′ End Of The Latency-Associated Transcript Produces A Protein In Infected Rabbits, Guey-Chuen Perng, Barak Maguen, Ling Jin, Kevin R. Mott, John Kurylo, Lbachir Benmohamed, Ada Yukht, Nelson Osorio, Anthony B. Nesburn, Gail A. Henderson, Melissa Inman, Clinton J. Jones, Steven L. Wechsler

School of Veterinary and Biomedical Sciences: Faculty Publications

Following primary ocular infection, herpes simplex virus type 1 (HSV-1) establishes a lifelong latent infection in sensory neurons of the trigeminal ganglia. Latency-associated transcript (LAT), the only known viral gene abundantly transcribed during HSV-1 neuronal latency, is required for high levels of reactivation. Recently we showed that three different mutants that do not alter the LAT promoter but contain deletions within the 5′ end of the primary LAT transcript affect viral virulence (G. C. Perng et al., J. Virol. 75:9018-9028, 2001). In contrast, in LAT-null mutants viral virulence appears unaltered (T. M. Block et al., Virology 192:618-630, 1993; D. C. …

Challenges, Strategies, And Tools For Research Scientists: Using Web-Based Information Resources, Danielle Bodrero Hoggan Jul 2002

Challenges, Strategies, And Tools For Research Scientists: Using Web-Based Information Resources, Danielle Bodrero Hoggan

E-JASL 1999-2009 (Volumes 1-10)

Scientists face many challenges in harnessing web-based resources. Information overload, misinformation, fees, poorly designed navigation, and loss of browsability all hamper the scientist searcher. In addition, many scientists rely on only one or two databases and often miss unique information that is available through other sources. Librarians can team up with scientists to develop strategies to overcome the challenges of web-based information. For example, a librarian can teach effective information seeking techniques, including how to use controlled vocabularies, how to evaluate information on the web, and how to complement web-based resources with print resources. Librarians can also help scientists to …

Reducing Childhood Pedestrian Injuries: Individual Risk Factors (Chapter 3), Katherine Kaufer Christoffel, Lizette Peterson, David Dilillo Jul 2002

Reducing Childhood Pedestrian Injuries: Individual Risk Factors (Chapter 3), Katherine Kaufer Christoffel, Lizette Peterson, David Dilillo

Department of Psychology: Faculty Publications

Most factors influencing the risk of pedestrian injury for children are based on family considerations or community norms, not on individuals. Nevertheless, individual risk factors should be considered when planning prevention programs (Christoffel, Donovan et al. 1996). The potential importance of individual traits has been extensively studied in the hope of finding a factor that could be modified. Considerations of the individual are important because they largely define the child’s risk of injury, even while walking with others. The causal sequence of a child walking to a particular site at a particular time where he or she is injured is …

Reducing Childhood Pedestrian Injuries: Proceedings Of A Multidisciplinary Conference, Richard A. Schieber, Maria Vegega Jul 2002

Reducing Childhood Pedestrian Injuries: Proceedings Of A Multidisciplinary Conference, Richard A. Schieber, Maria Vegega

Public Health Resources

EXECUTIVE SUMMARY
Motor vehicle crashes are associated with one of every five deaths among children 1 to 14 years of age in the United States, and pedestrian injuries account for a third of them. Compared with occupant injuries, pedestrian injuries are more severe; death is five times more likely to occur among those injured. In 1999, 533 child pedestrians were killed, and at least 30,000 children were nonfatally injured in traffic. Another 200 were killed in non-traffic areas, including driveways, sidewalks, and parking lots. Traumatic brain injury accounts for more than half the fatalities.
Dr. Schieber noted that the decline …

A Mutation In The Latency-Related Gene Of Bovine Herpesvirus 1 Disrupts The Latency Reactivation Cycle In Calves, Melissa Inman, Luciane Lovato, Alan R. Doster, Clinton J. Jones Jul 2002

A Mutation In The Latency-Related Gene Of Bovine Herpesvirus 1 Disrupts The Latency Reactivation Cycle In Calves, Melissa Inman, Luciane Lovato, Alan R. Doster, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

Bovine herpesvirus 1 (BHV-1) is an important pathogen of cattle, and infection is usually initiated via the ocular or nasal cavity. Following acute infection, the primary site for BHV-1 latency is the sensory neuron. Reactivation from latency occurs sporadically, resulting in virus shedding and transmission to uninfected cattle. The only abundant viral transcript expressed during latency is the latency-related (LR) RNA, suggesting that it mediates some aspect of latency. An LR mutant was constructed by inserting three stop codons near the beginning of the LR-RNA, suggesting that expression of LR proteins would be altered. The LR mutant grew with wild-type …

In-Home Prenatal Nutrition Intervention Increased Dietary Iron Intakes And Reduced Low Birthweight In Low-Income African-American Women, Chiquita Briley, Nicole L. Flanagan, Nancy M. Lewis Jul 2002

In-Home Prenatal Nutrition Intervention Increased Dietary Iron Intakes And Reduced Low Birthweight In Low-Income African-American Women, Chiquita Briley, Nicole L. Flanagan, Nancy M. Lewis

Department of Nutrition and Health Sciences: Faculty Publications

Low birthweight (LBW), defined as an infant weighing less than 2,500 grams (1), is a major determinant of infant mortality and contributes to infant and childhood morbidity and increased healthcare costs (2-4). LBW occurs due to preterm delivery (length of gestation less than 37 weeks), growth retardation, or both (2). In the United States, higher rates of LBW occur in urban areas with high concentrations of low-income ethnic minorities (5). Results of the 1997 Pediatric Nutrition Surveillance indicate that the rate of LBW in the United States was 13% for African-American infants, and 8% for whites (6). Healthy People 2010 …

Phylogenetic Analysis Of Brazilian Bovine Viral Diarrhea Virus Type 2 (Bvdv-2) Isolates: Evidence For A Subgenotype Within Bvdv-2, Eduardo F. Flores, Julia F. Ridpath, Rudi Weiblen, Fernanda S. F. Vogel, Laura H.V.G. Gil Jun 2002

Phylogenetic Analysis Of Brazilian Bovine Viral Diarrhea Virus Type 2 (Bvdv-2) Isolates: Evidence For A Subgenotype Within Bvdv-2, Eduardo F. Flores, Julia F. Ridpath, Rudi Weiblen, Fernanda S. F. Vogel, Laura H.V.G. Gil

School of Veterinary and Biomedical Sciences: Faculty Publications

Phylogenetic analysis divides bovine viral diarrhea viruses (BVDV) into two different genotypes (BVDV1 and BVDV2). BVDV1 strains have been further subdivided into two to 11 subgenotypes. Phylogenetic analysis of BVDV2 isolates, however, has not been able to identify discrete subgenotypes. In this study, we identified six South American BVDV2 strains and one North American BVDV2 strain that cluster to a separate genetic group within BVDV2, thus representing a distinct subgenotype. The 5’ untranslated region (UTR) sequence homology between these six strains and other BVDV2 from North America, Europe and Asia (81.7%) is lower than the homology used to segregate BVDV1 …

The Need For Proximal Mechanisms To Understand Individual Differences In Altruism, Gustavo Carlo, Rick A. Bevins Jun 2002

The Need For Proximal Mechanisms To Understand Individual Differences In Altruism, Gustavo Carlo, Rick A. Bevins

Department of Psychology: Faculty Publications

An "Open Peer Commentary" on the article "Altruism and selfishness" by Howard Rachlin.

There are three concerns regarding Rachlin’s altruism model. First, proximal causal mechanisms such as those identified by cognitive neuroscientists and behavioral neuropharmacologists are not emphasized. Second, there is a lack of clear testable hypotheses. And third, extreme forms of altruism are emphasized rather than common forms. We focus on an overarching theme – proximal mechanisms of individual differences in altruism.

Would Smokers With Schizophrenia Benefit From A More Flexible Approach To Smoking Treatment?, Dennis E. Mcchargue, Susy B. Gulliver, Brian Hitsman Jun 2002

Would Smokers With Schizophrenia Benefit From A More Flexible Approach To Smoking Treatment?, Dennis E. Mcchargue, Susy B. Gulliver, Brian Hitsman

Department of Psychology: Faculty Publications

We evaluated literature that addresses the notion that flexible smoking treatment approaches are warranted for smokers with a diagnosis of schizophrenia. Understanding the biological and psychological mechanisms that increase the likelihood of smoking and decrease the motivation to quit for these individuals is addressed within the framework of a neurobiological model. We provide a brief overview of the limited smoking cessation treatment literature for patients with schizophrenia and compare abstinence-focused versus reduction-focused treatment modalities. The potential utility of the reduction-focused approach to tobacco treatment for these smokers is evaluated. Suggestions for future research to address the utility and efficacy of …

Factors Influencing Children To Self-Disclose Sexual Abuse, Mary L. Paine, David J. Hansen Jun 2002

Factors Influencing Children To Self-Disclose Sexual Abuse, Mary L. Paine, David J. Hansen

Department of Psychology: Faculty Publications

Self-disclosure by victims of child sexual abuse (CSA) is critical to initiate legal and therapeutic intervention. Unfortunately, research indicates that lengthy delays in disclosure and even nondisclosure are common. A comprehensive review of the clinical and research literature on CSA and an overview of related bodies of literature was conducted. Areas addressed include the context of sexual abuse as it relates to disclosure, the context and elements of children’s disclosures, motivational factors inhibiting disclosure, and models of the disclosure process. Ancillary and analogue research on secrecy and disclosure are also reviewed. Implications for future research and practice are discussed.

Too Many Of A Good Thing? The Effects Of Multiple Motivations On Stress, Cost, Fulfillment, And Satisfaction , Marc T. Kiviniemi, Mark Snyder, Allen M. Omoto

Department of Psychology: Faculty Publications

Individuals engage in behaviors to satisfy motivations and can engage in the same behavior to satisfy a variety of different motivations. Previous research has examined how differences in the overall amount of motivation influence outcomes but has not addressed how differences in the number of conceptually distinct motivations one has for a particular action influence outcomes. In two longitudinal field studies, individuals with more than one motivation for volunteering experienced greater negative outcomes than did those who volunteered to satisfy a single motivation. A laboratory study manipulated the number of motivations individuals had for engaging in a volunteer activity. Individuals …

What Do We Assess When We Assess A Big 5 Trait? : A Content Analysis Of The Affective, Behavioral, And Cognitive Processes Represented In Big 5 Personality Inventories, Lisa M. Pytlik Zillig, Scott H. Hemenover, Richard A. Dienstbier

Department of Psychology: Faculty Publications

What are personality traits? Are all “broad” traits equally broad in the constructs they encompass and in the pervasiveness of their effects? Or are some traits more or less affective, behavioral, or cognitive in nature? The present study examined these issues as they applied to the Big 5 traits of Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness. Expert and novice raters judged the extent to which items from four popular Big 5 inventories contain behavioral, cognitive, or affective components. Traits and inventories were then compared in terms of their relative assessment of these components. Results indicate convergence among inventories but remarkable …

Generalizing The Dynamic Field Theory Of The A-Not-B Error Beyond Infancy: Three-Year-Olds’ Delay- And Experience-Dependent Location Memory Biases, Anne R. Schutte, John P. Spencer Mar 2002

Generalizing The Dynamic Field Theory Of The A-Not-B Error Beyond Infancy: Three-Year-Olds’ Delay- And Experience-Dependent Location Memory Biases, Anne R. Schutte, John P. Spencer

Department of Psychology: Faculty Publications

Thelen and colleagues recently proposed a dynamic field theory (DFT) to capture the general processes that give rise to infants’ performance in the Piagetian A-not-B task. According to this theory, the same general processes should operate in noncanonical A-not-B-type tasks with children older than 12 months. Three predictions of the DFT were tested by examining 3-year-olds’ location memory errors in a task with a homogeneous task space. Children pointed to remembered locations after delays of 0 s to 10 s. The spatial layout of the possible targets and the frequency with which children moved to each target was varied. As …

The purpose of this study was to observe the effects of defendant remorse on monetary damages awarded to a plaintiff in a malpractice case. In two experiments, the physician-defendant expressed remorse at the time of the incident and again at trial, expressed remorse at trial, explicitly demonstrated a lack of remorse at trial, or made no mention of remorse (or a lack thereof). Participants decided how much money to award to the plaintiff and evaluated both the plaintiff and the defendant on several dimensions. Participants awarded greater compensation when the physician expressed remorse at the time of the incident than …

The Development Of A Measure Of Prosocial Behaviors For Late Adolescents, Gustavo Carlo, Brandy A. Randall Feb 2002

The Development Of A Measure Of Prosocial Behaviors For Late Adolescents, Gustavo Carlo, Brandy A. Randall

Department of Psychology: Faculty Publications

The correlates and structure of prosocial behaviors in late adolescents were examined using a newly constructed, multidimensional measure. In Study 1, 249 college students (145 women; M age = 19.9 years) were administered the Prosocial Tendencies Measure (PTM) which assesses 6 types of prosocial behaviors: altruistic, compliant, emotional, dire, public, and anonymous. Measures of sympathy, perspective taking, personal distress, social desirability, global prosocial behaviors, social responsibility, ascription of responsibility, vocabulary skills, and prosocial moral reasoning were also completed. Test-retest reliability and further validity of the PTM were demonstrated in Study 2 with a sample of 40 college students (28 women; …
