Drive, Incentive, And Reinforcement: The Antecedents And Consequences Of Motivation, Roy Wise

Department of Psychology: Faculty Publications

The aim of scientific explanation is to characterize the important antecedents of observable (or at least objectively confirmable) events. Explanations of behavior in terms of motivational states are appeals to unobservable, internal events for interpretations of behavior that is variable under apparently constant external stimulus conditions (see, e.g., Brown, 1953; Hinde, 1960). To be identified as the cause of a behavior, the unobservable event or condition must preexist the behavioral event to be explained. A behavior cannot be explained by its consequences, though it may be explained as a consequence of similar events in the animal's history. Scientific explanation involves …

Utilities Of Dentin Regeneration Among Insured And Uninsured Adults, Amid I. Ismail, Stephen Birch, Woosung Sohn, James M. Lepkowski, Robert Belli

Department of Psychology: Faculty Publications

Objectives: This population-based study measured utilities (preferences measured under conditions of uncertainty) of dentin regeneration (DR), a potential new therapy, root canal therapy (RCT), and extraction (EXT).
Methods: A representative sample of dentate adults (aged 18–69 years) was randomly selected from the Detroit area. A computer program was used to administer the standard gamble (SG) method and record utility score (US) for treatment options of a tooth with reversible pulpitis using the SG method. For the SG method, two anchor states were used: filled tooth with full oral health and filled tooth with severe and continuous pain leading to EXT. …

Parenting, Julia C. Torquati

Department of Psychology: Faculty Publications

How can parents successfully care for their children in the context of homelessness? This is a significant question because families with children represent approximately 40 percent of the homeless population in the United States, and the number of homeless children has been growing since the early 1980s. Negative consequences of homelessness to children’s health, education, and emotional and social development have been well documented. Homeless families in the United States can be considered a subset of limited-resource families, and as such they share some of the same challenges to effective parenting. However, homeless parents face additional challenges, and these challenges …

The Economic Basis Of Cooperation: Tradeoffs Between Selfishness And Generosity, Jeffrey R. Stevens, David W. Stephens

Department of Psychology: Faculty Publications

The current study examined the economics of cooperation in controlled-payoff games by using captive blue jays, Cyanocitta cristata. This investigation used a special feeding apparatus to test for the stability of cooperative choice in a series of iterated games. The jays experienced experimentally determined game theoretical payoff matrices, which determined the distribution of food to themselves and their opponent, depending on their decision to cooperate or defect. The experiment tested four game matrices, called the cooperate only, defect only, prisoner’s dilemma, and opponent control treatments. This study found little cooperation in the defect only and prisoner’s dilemma treatments. Cooperation …

Why Be Nice? Psychological Constraints On The Evolution Of Cooperation, Jeffrey R. Stevens, Marc D. Hauser

Department of Psychology: Faculty Publications

Animals often aid others without gaining any immediate benefits. Although these acts seem to reduce the donor’s fitness, they are only apparently altruistic. Donors typically help because they or their kin receive future benefits or avoid costly punishment. Reciprocal altruism— alternating the roles of donor and recipient—has been a well-studied form of cooperation among non-kin because of its intuitive appeal in explaining human cooperation. Despite immense theoretical interest, little empirical evidence substantiates the biological importance of reciprocal altruism in non-human animals. We propose that this is because psychological mechanisms constrain its application in cooperative contexts. In particular, we contend that …

Barriers To Community Mental Health Services For Latinos: Treatment Considerations, Haig Kouyoumdjian, Byron L. Zamboanga, David J. Hansen

Department of Psychology: Faculty Publications

The underutilization of mental health services by Latinos has been a growing concern in research and clinical practice. This has become increasingly important as the population of Latinos in the United States rapidly rises and the evidence that many are not receiving needed mental health services accumulates. To provide an understanding of the issues, this article provides an overview of risk factors that may influence the mental health of Latinos and examines prevalence rates of psychopathology and service utilization trends. This article then presents a comprehensive review of the socioeconomic, cultural, and psychotherapeutic barriers that prevent Latinos from receiving community …

Sexual Risk Taking In Adolescence: The Role Of Self-Regulation And Attraction To Risk, Marcela Raffaelli, Lisa J. Crockett

Department of Psychology: Faculty Publications

Precursors of adolescent sexual risk taking were examined in a multiethnic sample consisting of 443 children (51% girls) of National Longitudinal Survey of Youth participants. Respondents were 12–13 years old in 1994 and 16–17 in 1998. Controlling for demographic and contextual factors, self-regulation—but not risk proneness—was significantly (modestly) associated with overall sexual risk taking 4 years later, Analyses of individual sexual behaviors indicated that self-regulation may affect choices made after becoming sexually active (e.g. number of partners) rather than the initiation of sexual activity. Measures of parent and peer influence had independent effects on sexual risk taking but did not …

Serotonergic Agents And Alcoholism Treatment: A Simulation, Scott F. Stoltenberg

Department of Psychology: Faculty Publications

Background: Those with early-onset alcoholism may better respond to ondansetron (a 5-HT3 receptor antagonist) than to selective serotonin reuptake inhibitor (SSRI) treatment, whereas those with late-onset alcoholism may present the reverse response pattern. Johnson and colleagues proposed a model that attempts to explain the observed treatment response patterns of those with early and late alcoholism onset by focusing on the influence of a common genetic variant in the serotonin transporter regulatory region (5-HTTLPR) on serotonin (5-HT) and dopamine (DA) system function.
Methods: The present study formalizes and extends Johnson’s descriptive model into a computer simulation consisting of differential equations. For …

Bacteriolytic Activity Of Selected Vertebrate Sera For Borrelia Burgdorferi Sensu Stricto And Borrelia Bissettii, Amy J. Ullmann, Robert S. Lane, Klaus Kurtenbach, Michael Miller, Martin E. Schriefer, Nordin Zeidner, Joseph Piesman

United States Public Health Resources

An in vitro assay to evaluate the bacteriolytic activity of the complement pathway was applied to 2 strains of Borrelia bissettii, CO501 and DN127, and compared with that of B. burgdorferi sensu stricto B31. Sera from mule deer ( Odocoileus hemionus) and the Western Fence lizard ( Sceloporus occidentalis) were completely borreliacidal for B. burgdorferi and for both strains of B. bissettii. Serum from Bobwhite quail ( Colinus virginianus) was nonlytic for B. burgdorferi and partially lytic for B. bissettii strains, CO-501 and DN127. Serum from a New Zealand White rabbit ( Oryctolagus cuniculus) …

Parenting Characteristics Of Women Reporting A History Of Childhood Sexual Abuse, David Dilillo, Amy Damashek

Department of Psychology: Faculty Publications

This article reviews research on the parenting characteristics of female survivors of childhood sexual abuse (CSA). Various aspects of parenting are considered, including (a) childbearing patterns, (b) the intergenerational transmission of CSA, (c) maternal reactions to child CSA disclosure, (d) parenting skills and behaviors, (e) parental violence toward children, (f) attitudes toward parenting, and (g) adjustment of survivors’ children. Overall patterns suggest CSA survivors may experience difficulties with some aspects of parenting. Among the more consistent trends are findings that survivors may have difficulties establishing clear generational boundaries with their children, may be more permissive as parents, and may be …

Effects Of Neurobehavioral Assessment On Feeding And Weight Gain In Preterm Neonates, T. E. Senn, K. A. Espy

Developmental Cognitive Neuroscience Laboratory: Faculty Publications

Neonatal intensive care unit personnel and parents often are concerned that developmental assessment will tire preterm neonates and impair their feeding ability and subsequent weight gain. Therefore, the amount of fluid consumed by 108 preterm neonates (≤36.5 wk gestational age) was compared before and after administration of the Neurobehavioral Assessment of the Preterm Infant (NAPI). In addition, the weight gain of 35 preterm neonates who were administered the NAPI was compared with that of a matched control group of 35 preterm neonates who were not administered the NAPI. There were no differences in the amount of fluid consumed before and …

Incidence And Correlates Of Breast Milk Feeding In Hospitalized Preterm Infants, K. A. Espy, T. E. Senn

Developmental Cognitive Neuroscience Laboratory: Faculty Publications

The majority of epidemiological studies of breast feeding have been conducted in healthy, fullterm infant samples. Little is known about the incidence and correlates of breast milk feeding in preterm infants, particularly in those born outside of metropolitan areas. Therefore, hospital medical charts of 151 consecutively admitted preterm infants (

Effects Of Environmental Measures On Intelligence In Young Children: Growth Curve Modeling Of Longitudinal Data, K. A. Espy, Victoria J. Molfese, L. Dilalla

Developmental Cognitive Neuroscience Laboratory: Faculty Publications

Examined the effects of different environmental measures on individual intellectual growth patterns in 105 young children participating in a longitudinal study. Intelligence (Stanford-Binet, 4th edition) was measured at ages 3 through 6 yrs, and child's environment was assessed at age 3 years using SES data and scores on the Home Observation for Measurement of the Environment (HOME) Inventory. Growth curve analyses revealed that HOME scores exerted a constant influence on the expected composite, verbal, and nonverbal intellectual skills at each age. Only SES influenced the rate of growth, specifically nonverbal intellectual skills. The magnitudes of these effects were moderate, but …

The “Sexually Abused Child”: Potential Mechanisms Of Adverse Influences Of Such A Label, Gabriel Holguin, David J. Hansen

Department of Psychology: Faculty Publications

Labeling and the effects of labeling have been extensively researched in the psychological literature in a variety of different contexts. For example, labeling has been empirically shown to lead to lowered expectancies of behavior and achievement, which can then contribute to the potential for the occurrence of a self-fulfilling prophecy with adverse consequences. Another area that has been extensively researched, with a dramatic increase in the literature base in recent history, is that of child sexual abuse (CSA). Despite various shortcomings of the research literature, the consistent findings have been identification of a variety of negative correlates and symptomatologies associated …

Presentation Of Allergen In Different Food Preparations Affects The Nature Of The Allergic Reaction: A Case Series, K. E. C. Grimshaw, R. M. King, Julie A. Nordlee, S. L. Hefle, John O. Warner, J. O.'B. Hourihane

Department of Food Science and Technology: Faculty Publications

Background: Characterization of fatal and nonfatal reactions to food indicates that the majority of reactions are due to the ingestion of prepared foods rather than the nonprocessed allergen. In an ongoing study that used a double-blind placebo-controlled food challenge to investigate peanut allergy and clinical symptoms, the observed reaction severity in four of the first six subjects was greater than anticipated. We hypothesized that this was due to differences in the composition of the challenge vehicle.

Objective: The aim was to investigate whether the severity of observed challenge reactions would be repeated on rechallenge with a lower fat …

Juror Sensitivity To The Cross-Race Effect, Jordan Abshire, Brian H. Bornstein

Department of Psychology: Faculty Publications

Black and White mock jurors’ sensitivity to the cross-race effect was investigated by varying the race of the eyewitness in a simulated murder trial of a Black defendant. Participants heard an audiotape of a trial after which they rendered a verdict and rated the credibility of the witnesses. White participants found the prosecution witnesses (including the eyewitness) more credible, and the defense witness less credible, than did Black participants; they were also more likely to find the defendant guilty. The Black eyewitness was perceived as more credible than was the White eyewitness, but eyewitness race had no effect on verdict. …

Tomographic Reconstruction Of Treponemal Cytoplasmic Filaments Reveals Novel Bridging And Anchoring Components, Jacques Izard, Bruce F. Mcewen, Rita M. Barnard, Thomas Portuese, William A. Samsonoff, Ronald J. Limberger

Department of Food Science and Technology: Faculty Publications

An understanding of the involvement of bacterial cytoplasmic filaments in cell division requires the elucidation of the structural organization of those filamentous structures. Treponemal cytoplasmic filaments are composed of one protein, CfpA, and have been demonstrated to be involved in cell division. In this study, we used electron tomography to show that the filaments are part of a complex with a novel molecular organization that includes at least two distinct features decorating the filaments. One set of components appears to anchor the filaments to the cytoplasmic membrane. The other set of components appears to bridge the cytoplasmic filaments on the …

A Diagnostic Strategy To Determine The Shiga Toxin-Producing Escherichia Coli 0157 Status Of Pens Of Feedlot Cattle, David R. Smith, J.T. Gray, Rodney A. Moxley, S.M. Younts-Dahl, M.P. Blackford, S. Hinkley, L.L. Hungerford, C.T. Milton, Terry J. Klopfenstein

School of Veterinary and Biomedical Sciences: Faculty Publications

Although cattle are reservoirs, no validated method exists to monitor Shiga toxin-producing Escherichia coli 0157 (STEC 0157) on farms. In 29 Midwestern United States feedlot pens we compared culturing feces from the individual cattle to: (1) culturing rope devices that cattle rub or chew; and (2) culturing a composite of fecal pats. Eighty-six per cent (68-96 %) of pens were classified correctly using rope devices to detect pens with at least 16 % of the cattle shedding STEC 0 157 [sensitivity = 82 % (57-96 %); specificity = 92 % (62-100 %)]. Ninety per cent of pens (73-98 %) were …

Herpes Simplex Virus Type 2 Induces Rapid Cell Death And Functional Impairment Of Murine Dendritic Cells In Vitro, Clinton J. Jones, M. Fernandez, K. Herc, L. Bosnjak, M. Miranda-Saksena, R. A. Boadle, A. Cunningham

School of Veterinary and Biomedical Sciences: Faculty Publications

Dendritic cells (DC) are critical for stimulation of naive T cells. Little is known about the effect of herpes simplex virus type 2 (HSV-2) infection on DC structure or function or if the observed effects of HSV-1 on human DC are reproduced in murine DC. Here, we demonstrate that by 12 h postinfection, wild-type (wt) HSV-2 (186) abortively infected murine bone marrow-derived DC and induced early cell death compared to UV-inactivated HSV-2 or mock-infected DC. HSV-2-induced loss of DC viability was more rapid than that induced by HSV-1 and was due, in part, to apoptosis, as shown by TEM, caspase-3 …

The Gene That Encodes The Herpes Simplex Virus Type 1 Latency-Associated Transcript Influences The Accumulation Of Transcripts (Bcl-XL And Bcl-XS) That Encode Apoptotic Regulatory Proteins, Weiping Peng, Gail A. Henderson, Guey-Chuen Perng, Anthony B. Nesburn, Steven L. Wechsler, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

The herpes simplex virus type 1 latency-associated transcript (LAT) inhibits apoptosis. We demonstrate here that LAT influences the accumulation of the Bcl-x_L transcript versus the Bcl-x_S transcript in Neuro-2A cells. Bcl-x_L encodes an antiapoptotic protein, whereas Bcl-x_S encodes a proapoptotic protein. Promoting the accumulation of Bcl-x_L in neurons may inhibit apoptosis, thus enhancing the latency-reactivation cycle.

Adolescent Religiosity And Sexuality: An Investigation Of Reciprocal Influences, Sam A. Hardy, Marcela Raffaelli

Department of Psychology: Faculty Publications

The present study examined potential bi-directional associations between religiosity and first sexual intercourse. The sample, drawn from the National Longitudinal Survey of Youth, included 303 teens (22% Hispanic, 35% Black, 43% White; 53% male) aged 15–16 in 1996 and 17–18 in 1998. All teens included in the sample were virgins at Time 1. In the longitudinal analyses, higher Time 1 religiosity (a composite of importance of religion and frequency of church attendance) was associated with a lower likelihood of first sexual intercourse between Time 1 and Time 2. However, transition to sexual activity between Time 1 and Time 2 was …

Effects Of Chronic Caffeine Pre-Exposure On Conditioned And Unconditioned Psychomotor Activity Induced By Nicotine And Amphetamine In Rats, M. I. Palmatier, E. Y. K. Fung, Rick A. Bevins

Department of Psychology: Faculty Publications

Three experiments examined the effects of chronic preexposure to caffeine on the subsequent conditioned and unconditioned locomotor activating effects of nicotine or amphetamine in rats. Rats were given daily intraperitoneal injections of caffeine anhydrous (0, 10 or 30 mg/kg base) for 30 days. Conditioning (environment-drug pairings) began after the last day of caffeine pre-exposure. Preexposure to 30 mg/kg of caffeine enhanced the acute and chronic locomotor effects of amphetamine (0.5 mg/kg). A similar enhancement of activity was not seen with the high (0.421 mg/kg base) or low dose (0.175 mg/kg) of nicotine. In a drug-free test, the distinct environment paired …

Testing The Dynamic Field Theory: Working Memory For Locations Becomes More Spatially Precise Over Development, Anne R. Schutte, John P. Spencer, Gregor Schöner

Department of Psychology: Faculty Publications

The dynamic field theory predicts that biases toward remembered locations depend on the separation between targets, and the spatial precision of interactions in working memory that become enhanced over development. This was tested by varying the separation between A and B locations in a sandbox. Children searched for an object 6 times at an A location, followed by 3 trials at a B location. Two- and 4-year-olds’, but not 6-year-olds’, responses were biased toward A when A and B were 9-in. and 6-in. apart. When A and B were separated by 2 in., however, 4- and 6-year-olds’ responses were biased …

Barriers To Physicians’ Decisions To Discuss Hospice: Insights Gained From The United States Hospice Model, E. Kiernan Mcgorty, Brian H. Bornstein

Department of Psychology: Faculty Publications

Due to its comprehensive and cost-saving design, hospice has become a critical component of health care. Physicians have become the primary gatekeepers to information on hospice and sources of referral to hospice. However, many physicians do not discuss hospice options until late in the disease course, when patients and their families are no longer able to benefit from hospice services. Although physicians, as well as patients and hospice personnel, cite patient and hospice structure factors as barriers, the present article will focus on barriers physicians have more control over, such as their discomfort discussing terminality and fear of losing contact …

Acquaintance Rape Of College Students, Rana Sampson

United States Public Health Resources

Rape is the most common violent crime on American college campuses today. This guide describes the problem of acquaintance rape of college students, addressing its scope, causes and contributing factors; methods for analyzing it on a particular campus; tested responses; and measures for assessing response effectiveness. With this information, police and public safety officers can more effectively prevent the problem.
Researchers believe that college rape prevention programs, including the most widely used ones, are insufficient. Most rapes are unreported, perhaps giving campus administrators and police the false impression that current efforts are adequate. In addition, campus police may be influenced …

Adult Survivors Of Childhood Abuse: An Analysis Of Coping Mechanisms Used For Stressful Childhood Memories And Current Stressors, Kristine T. Futa, Cindy L. Nash, David J. Hansen, Calvin P. Garbin

Department of Psychology: Faculty Publications

Coping mechanisms used to deal with stressful childhood memories and current stressors were assessed for 196 women in each of 4 groups: no abuse history, sexual abuse history, physical abuse history, and both sexual and physical abuse history. Current psychological adjustment was also examined. Discriminant function analyses revealed a variety of significant differences between the groups in use of strategies for coping with memories of abuse or another childhood stressor. There was no relationship between childhood history of abuse and the manner in which women coped with a current stressor. Women with an abuse history reported significantly poorer adult adjustment …

The Teenage Inventory Of Social Skills: Reliability And Validity Of The Spanish Translation, Cándido J. Inglés, María D. Hidalgo, F. Xavier Méndez, Heidi M. Inderbitzen

Department of Psychology: Faculty Publications

Peer relationships play a critical role in the development of social skills and personal feelings essential for personal growth and life-long adjustment (Hansen, Nangle, & Meyer, 1998), and are a key factor in the development of personal identity and independence from the family circle (Mayseless, Wiseman, & Hai, 1998). Children and adolescents who are popular or accepted by their peers receive more social reinforcement, which improves their adaptation, not only in social areas but also in personal and school ones (Inderbitzen, Walters, & Bukowski, 1997; La Greca & Lopez, 1998). Acceptance or popularity among peers is closely connected to prosocial …

The Economics Of Managing Wildlife Disease, Richard D. Horan, Christopher A. Wolf

Michigan Bovine Tuberculosis Bibliography and Database

The spread of infectious disease among and between wild and domesticated animals has become a major problem worldwide. Upon analyzing the dynamics of wildlife growth and infection when the diseased animals cannot be identified separately from healthy wildlife prior to the kill, we find that harvest-based strategies alone have no impact on disease transmission. Other controls that directly influence disease transmission and/or mortality are required. Next, we analyze the socially optimal management of infectious wildlife. The model is applied to the problem of bovine tuberculosis among Michigan white-tailed deer, with non-selective harvests and supplemental feeding being the control variables. Using …

History Of Depression And Smoking Cessation Outcome: A Meta-Analysis, Brian Hitsman, Belinda Borrelli, Dennis E. Mcchargue, Bonnie Spring

Department of Psychology: Faculty Publications

The authors conducted a meta-analysis of published studies to (a) evaluate the premise that a history of major depression is associated with failure to quit smoking and (b) identify factors that moderate the relationship between history of depression and cessation outcome. Fifteen studies met the selection requirements and were coded for various study methodology and treatment characteristics. DSTAT was used to calculate individual study effect sizes, determine the mean effect size across studies, and test for moderator effects. No differences in either short-term (≤ 3 months) or long-term abstinence rates (≥ 6 months) were observed between smokers positive versus negative …

Effects Of A Multicomponent Intervention On Motivation And Sun Protection Behaviors Among Midwestern Beachgoers, Sherry Pagota, Dennis E. Mcchargue, R. Wayne Fuqua

Department of Psychology: Faculty Publications

Skin cancer is the most prevalent of all cancers in the United States. Although avoiding sun exposure and using sun protection reduces skin cancer risk, rates of such behaviors are moderate at best. The present study examined the impact of a multicomponent intervention that aimed to increase the saliency of skin cancer risk while promoting the use of sun protection. Midwestern beachgoers (n =100) participated in an intervention or questionnaire-only control group. Sun protection, stage of change, and sun exposure were measured at baseline and 2-month follow-up. The intervention group significantly improved in sun protection use and stage of …
