Obama Cares About Visuo-Spatial Attention: Perception Of Political Figures Moves Attention And Determines Gaze Direction, Mark S. Mills, Kevin B. Smith, John R. Hibbing, Michael D. Dodd

Department of Psychology: Faculty Publications

Processing an abstract concept such as political ideology by itself is difficult but becomes easier when a background situation contextualizes it. Political ideology within American politics, for example, is commonly processed using space metaphorically, i.e., the political “left” and “right” (referring to Democrat and Republican views, respectively), presumably to provide a common metric to which abstract features of ideology can be grounded and understood. Commonplace use of space as metaphor raises the question of whether an inherently non-spatial stimulus (e.g., picture of the political “left” leader, Barack Obama) can trigger a spatially-specific response (e.g., attentional bias toward “left” regions of …

Disagreeing On Whether Agreement Is Persuasive: Perceptions Of Expert Group Decisions, Ashley M. Votruba, Virginia S. W. Kwan

Department of Psychology: Faculty Publications

While expert groups often make recommendations on a range of non-controversial as well as controversial issues, little is known about how the level of expert consensus—the level of expert agreement—influences perceptions of the recommendations. This research illustrates that for non-controversial issues expert groups that exhibit high levels of agreement are more persuasive than expert groups that exhibit low levels of agreement. This effect is mediated by the perceived entitativity—the perceived cohesiveness or unification of the group—of the expert group. But for controversial issues, this effect is moderated by the perceivers’ implicit assumptions about the group composition. When perceivers are provided …

Parasitology In An Archaeological Context: Analysis Of Medieval Burials In Nivelles, Belgium, S. E. Rácz, Elisa Pucu De Araujo, E. Jensen, C. Mostek, Johnica J. Morrow, M. L. Van Hove, R. Bianucci, D. Willems, F. Heller, Adauto Araujo, Karl Reinhard

Karl Reinhard Publications

Coprolites were recovered from three burials near the Grand Place of Nivelles, Belgium. These remains yielded evidence of geohelminth parasitism. The evidence contributes to studies of differential parasite egg preservation related to the taphonomic conditions within the three burials. Using coprolite analysis techniques, parasite egg concentrations were quantified for each burial. Coprolites from the individual in Burial 122 were abnormally large and abundant, indicating an intestinal blockage. Additionally, this individual hosted an extremely high number of parasites evinced by the calculated parasite egg concentrations (Trichuris trichiura = 1,577,679 total eggs; Ascaris lumbricoides = 202,350 total eggs). Statistical analyses revealed …

Paleoparasitology – Human Parasites In Ancient Material, Adauto Araújo, Karl Reinhard, Luiz Fernando Ferreira

Karl Reinhard Publications

Parasite finds in ancient material launched a new field of science: paleoparasitology. Ever since the pioneering studies, parasites were identified in archaeological and paleontological remains, some preserved for millions of years by fossilization. However, the paleoparasitological record consists mainly of parasites found specifically in human archaeological material, preserved in ancient occupation sites, from prehistory until closer to 2015. The results include some helminth intestinal parasites still commonly found in 2015, such as Ascaris lumbricoides, Trichuris trichiura and hookworms, besides others such as Amoebidae and Giardia intestinalis, as well as viruses, bacteria, fungi and arthropods. These parasites as a …

Forensic Palynological Analysis Of Intestinal Contents Of A Korean Mummy, Paulette Arguelles, Karl Reinhard, Dong Hoon Shin

Karl Reinhard Publications

Experimental studies show that pollen resides in the intestinal tract for a minimum of seven days to at least 21 days. Because of this long residence time, pollen analysis is an important avenue of forensic research. Pollen provides evidence of the environment of the decedent as well as foods and medicine. We analyzed a coprolite recovered from a Korean mummy. The decedent was a high-ranking general who lived during the 16th or 17th centuries. Twenty pollen types were recovered. These ranged from 100s to 10,000s of pollen grains per gram of coprolite. Importantly, comparison of the coprolite pollen spectrum to …

Determinants Of Rural Latino Trust In The Federal Government, Nathan Munier, Julia Albarracin, Keith Boeckelman

Department of Political Science: Faculty Publications

Trust in government is essential to democratic practice. This article analyzed the factors shaping trust in the federal government using a survey of 260 Mexican immigrants living in rural Illinois and in-depth interviews with 32 participants. To analyze these data, we drew a distinction between support for the regime (system of government that is relatively stable in a political system) and support for authorities (those who temporarily occupy positions of power) to test whether regime or authorities’ considerations shaped respondents’ political trust. The results showed that both considerations influenced trust in the federal government. We also found that a perception …

Planning Versus Action: Different Decision-Making Processes Predict Plans To Change One’S Diet Versus Actual Dietary Behavior, Marc T. Kiviniemi, Carolyn R. Brown-Kramer

Department of Psychology: Faculty Publications

Most health decision-making models posit that deciding to engage in a health behavior involves forming a behavioral intention which then leads to actual behavior. However, behavioral intentions and actual behavior may not be functionally equivalent. Two studies examined whether decision-making factors predicting dietary behaviors were the same as or distinct from those predicting intentions. Actual dietary behavior was proximally predicted by affective associations with the behavior. By contrast, behavioral intentions were predicted by cognitive beliefs about behaviors, with no contribution of affective associations. This dissociation has implications for understanding individual regulation of health behaviors and for behavior change interventions.

Negative Urgency And Emotion Regulation Strategy Use: Associations With Displaced Aggression, Jillian Panuzio Scott, David Dilillo, Rosalita C. Maldonado, Laura E. Watkins

Department of Psychology: Faculty Publications

The numerous public health consequences of interpersonal aggression highlight the necessity of a comprehensive understanding of factors influencing its perpetration. This study examined direct and interactive associations between negative urgency and emotion regulation strategy use in predicting displaced aggression under conditions of negative mood. Participants were 197 male and female undergraduate students who were randomly assigned to employ either cognitive reappraisal or expressive suppression in response to a negative mood induction. Immediately afterward, participants engaged in an analog displaced aggression task. Results revealed direct, positive associations between negative urgency and aggression. In addition, the use of suppression was associated with …

A Prospective Investigation Of Emotion Dysregulation As A Moderator Of The Relation Between Posttraumatic Stress Symptoms And Substance Use Severity, Matthew T. Tull, Joseph R. Bardeen, David Dilillo, Terri Messman-Moore

Department of Psychology: Faculty Publications

Despite strong evidence for an association between the experience of posttraumatic stress (PTS) symptoms and substance use, little is known about the particular individuals most at risk for prob-lematic substance use in response to PTS symptoms. Consequently, the goal of this study was to conduct a prospective investigation of the moderating role of emotion dysregulation (assessed through self-report and behavioral measures) in the relation between PTS symptoms and substance use 8 months later within a sample of 106 young adult women. No main effect of PTS symptoms on substance use was found. Instead, PTS symptoms were associated only with later …

Repeat Baseline Assessment In College-Age Athletes, Arthur C. Maerlender, Dennis L. Molfese

Department of Psychology: Faculty Publications

Repeat baseline testing scores from one collegiate Division I NCAA school were analyzed to determine the necessity of this practice. ImPACT tests were taken between 13 and 40 months apart (median 24 months; final N = 67). No significant difference in any test composite score was obtained; the number of tests exceeding chance levels of change was insignificant. The results do not support the recommendation for repeating baseline testing in college athletes; replication is recommended.

From Sex Objects To Human Beings: Masking Sexual Body Parts And Humanization As Moderators To Women’S Objectification, Philippe Bernard, Sarah Gervais, Jill Allen, Alice Delmée, Olivier Klein

Department of Psychology: Faculty Publications

Recent studies have shown that sexualized female bodies are objectified at a cognitive level. Research using the body-inversion recognition task, a robust indicator of configural (vs. analytic processing) within cognitive psychology, shows that for sexualized female bodies, people recognize upright and inverted bodies similarly rather than recognizing upright bodies better than inverted bodies (i.e., an inversion effect). This finding suggests that sexualized female bodies, like objects, are recognized analytically (rather than configurally). Nonetheless, it remains unclear when and why sexualized female bodies are objectified at a basic cognitive level. Grounded in objectification theory, the present experiments examine moderating factors that …

Impact Of Urban Nature On Executive Functioning In Early And Middle Childhood, Anne R. Schutte, Julia C. Torquati, Heidi L. Beattie

Department of Psychology: Faculty Publications

According to attention restoration theory, directed attention can become fatigued and then be restored by spending time in a restorative environment. This study examined the restorative effects of nature on children’s executive functioning. Sevento 8-year-olds (school aged, n = 34) and 4- to 5-year-olds (preschool, n = 33) participated in two sessions in which they completed an activity to fatigue attention, then walked along urban streets (urban walk) in one session and in a park-like area (nature walk) in another session, and finally completed assessments of working memory, inhibitory control, and attention. Children responded faster on the attention task after …

Repeated Administration Of Aripiprazole Produces A Sensitization Effect In The Suppression Of Avoidance Responding And Phencyclidine-Induced Hyperlocomotion And Increases D2 Receptor-Mediated Behavioral Function, Jun Gao, Rongyin Qin, Ming Li

Department of Psychology: Faculty Publications

The present study investigated how repeated administration of aripiprazole (a novel antipsychotic drug) alters its behavioral effects in two behavioral tests of antipsychotic activity and whether this alteration is correlated with an increase in dopamine D₂ receptor function. Male adult Sprague-Dawley rats were first repeatedly tested with aripiprazole (3, 10 and 30 mg/kg, subcutaneously (sc)) or vehicle in a conditioned avoidance response (CAR) test or a phencyclidine (PCP) (3.20 mg/kg, sc)-induced hyperlocomotion test daily for five consecutive days. After 2–3 days of drug-free retraining or resting, all rats were then challenged with aripiprazole (1.5 or 3.0 mg/kg, sc). Repeated …

Cognitive-Behavioral Treatment Of Social Anxiety Disorder And Comorbid Paranoid Schizophrenia, Monnica T. Williams, Michelle C. Capozzoli, Erica V. Buckner, David Yuska

Department of Psychology: Faculty Publications

We report on the cognitive-behavioral treatment (CBT) of a patient with comorbid social anxiety disorder (SAD), schizophrenia, and major depressive disorder, complicated by alcohol abuse. Symptoms included auditory hallucinations that commented on the patient’s behavior and paranoid thoughts. The paranoid symptoms affected his social interactions as this included the fear that his thoughts may be heard and judged by others. Therapeutic activities raised awareness as to how avoidance interferes with and perpetuates the cycle of depression and psychosis while maintaining symptoms of SAD. Psychoeducation was provided about factors that maintain social anxiety and increase social isolation. New skills were obtained …

Role Of The Α1 Blocker Doxazosin In Alcoholism: A Proof-Of-Concept Randomized Controlled Trial, George A. Kenna, Carolina L. Haass-Koffler, William H. Zywiak, Steven M. Edwards, Michael B. Brickley, Robert M. Swift, Lorenzo Leggio

Department of Psychology: Faculty Publications

Evidence suggests that the norepinephrine system represents an important treatment target for alcohol dependence (AD) and the α1-blocker prazosin may reduce alcohol drinking in rodents and alcoholic patients. The α1-blocker doxazosin demonstrates a more favorable pharmacokinetic profile than prazosin, but has never been studied for AD. A double-blind placebo-controlled randomized clinical trial was conducted in AD individuals seeking outpatient treatment. Doxazosin or matched placebo was titrated to 16 mg/day (or maximum tolerable dose). Drinks per week (DPW) and heavy drinking days (HDD) per week were the primary outcomes. Family history density of alcoholism (FHDA), severity of AD and gender were …

The Recruitment Paradox: Network Recruitment, Structural Position, And East German Market Transition, Richard A. Benton, Steve Mcdonald, Anna Manzoni, David F. Warner

Department of Sociology: Faculty Publications

Economic institutions structure links between labor-market informality and social stratification. The present study explores how periods of institutional change and post-socialist market transition alter network-based job finding, in particular informal recruitment. We highlight how market transitions affect both the prevalence and distribution of network-based recruitment channels: open-market environments reduce informal recruitment’s prevalence but increase its association with high wages. We test these propositions using the case of the former East Germany’s market transition and a comparison with West Germany’s more stable institutional environment. Following transition, workers in lower tiers increasingly turned toward formal intermediaries, active employee search, and socially “disembedded” …

Alcohol Expectancy, Drinking Behavior, And Sexual Victimization Among Female And Male College Students, Kimberly A. Tyler, Rachel M. Schmitz, Scott A. Adams

Department of Sociology: Faculty Publications

College students have high rates of heavy drinking, and this dangerous behavior is strongly linked to sexual victimization. Although research has examined risk factors for sexual assault, few studies have simultaneously studied the various pathways through which risks may affect sexual assault and how these pathways may be uniquely different among females and males. As such, the current study uses path analyses to examine whether alcohol expectancies mediate the relationship between social factors (e.g., hooking up, amount friends drink) and drinking behavior and experiencing sexual victimization, and whether drinking behavior mediates the relationship between alcohol expectancies and sexual victimization among …

Health-Related Strains And Subsequent Delinquency And Marijuana Use, Lisa Kort-Butler

Department of Sociology: Faculty Publications

General strain theory provides one framework for explaining the relationship between physical health and delinquency, pointing to mechanisms such as negative emotions, social bonds, and stress proliferation. Data from the National Longitudinal Study of Adolescent Health were used to examine these hypothetical mediators. Controlling for demographic factors, prior illicit behavior, and other strains, results from a series of regressions indicated that health-related strain (HRS) was positively associated with subsequent delinquency and marijuana use. Stressors at school were the primary mediators of these effects. Absences from school and social life due to health problems exerted an independent effect. The results lend …

The Effect Of Cati Questions, Respondents, And Interviewers On Response Time, Kristen Olson, Jolene D. Smyth

Department of Sociology: Faculty Publications

In this paper, we evaluate the joint effects of question, respondent, and interviewer characteristics on response time in a telephone survey. We include question features traditionally examined, such as the length of the question and format of response options, and features that have yet to be examined that are related to the layout and format of interviewer-administered questions. We examine how these question features affect the time to ask and answer survey questions and how different interviewers vary in their administration of these questions. This paper uses paradata from the Work and Leisure Today survey and uses cross-classified random effects …

Hard Times And Heart Break: Linking Economic Hardship And Relationship Distress, Deadric T. Williams, Jacob Cheadle, Bridget J. Goosby

Department of Sociology: Faculty Publications

We used the Fragile Families and Child Well-Being Study to examine an integrated mediational model linking economic hardship to relationship distress. Depressive symptoms, partner’s discord, parenting stress, and coparenting are combined into a joint model linking economic hardship to relationship distress among mothers and fathers in intimate relationships. Although economic hardship is significantly associated with each mediating factor, only discord is associated with both relationship distress and dissolution in the full model. Moreover, comparisons using multigroup structural equation modeling indicate that while economic hardship is associated with higher discord among both mothers and fathers, the influence is substantially larger among …

Maternal Depressive Symptoms And Adolescent Alcohol Use: The Mediating Role Of Youth Depressive Symptoms, Mindy Herman-Stahl, Lissette M. Saavedra, Antoio A. Morgan-Lopez, Scott P. Novak, Tara D. Warner, Diana H. Fishbein

Department of Sociology: Faculty Publications

The purpose of this study was to explore the influence of maternal depressive symptoms on adolescent alcohol use among a sample of Latino/Latina youth aged 10 to 16 years from a high-risk community. Direct and mediating effects of youth depressive symptoms, controlling for levels of concurrent emotion dysregulation, on alcohol use were examined. Participants consisted of 525 children and their mothers randomly sampled from low-income schools with high rates of substance use. The panel design included four waves, and we used structural equation modeling with a longitudinal mediational framework. Results indicated that the relationship between maternal depressive symptoms and adolescent …

Age And Lineup Type Differences In The Own-Race Bias, Lindsey E. Wylie, Shaina Bergt, Joshua Haby, Eve M. Brank, Brian H. Bornstein

Department of Psychology: Faculty Publications

The own-race bias (ORB) suggests that recognition for faces of one’s own race is superior to recognition of other-race faces. A popular explanation for the ORB is amount of interracial contact, which may have cohort effects for older and younger adults. We compared White younger and older adults on the ORB utilizing a hybrid facial recognition and full diagnostic lineup (i.e., simultaneous and sequential target absent and target present lineups) paradigm. Both younger and older adults demonstrated an ORB. Signal detection estimates suggest younger adults compared to older adults have better discrimination accuracy for own-race over other-race faces. Interracial contact …

Links Among Inflammation, Sexual Activity And Ovulation Evolutionary Trade-Offs And Clinical Implications, Tierney K. Lorenz, Carol M. Worthman, Virginia J. Vitzthum

Department of Psychology: Faculty Publications

Background and objectives: We examined a mechanism that may coordinate trade-offs between reproduction and immune response in healthy women, namely, changes in inflammation across the ovarian cycle.

Methodology: We investigated C-reactive protein (CRP), an inflammation marker, across two consecutive ovarian cycles in 61 Bolivian women. Participants provided saliva samples every other day, and dried blood spots on 5–6 days spread across weeks 2–3 of each cycle. Cycles were characterized as ovulatory/ anovulatory based on profiles of reproductive hormones. Participants also reported whether they were sexually partnered with a male or sexually abstinent during the study.

Results: High early-cycle, but not …

Longitudinal Predictors Of Homelessness: Findings From The National Longitudinal Survey Of Youth-97, Brittany Sznajder-Murray

Department of Sociology: Faculty Publications

Homeless youth represent a vulnerable and understudied population. Little research has prospectively identified factors that may place youth at risk for experiencing homelessness. The current study utilizes data from the National Longitudinal Survey of Youth-97 (NLSY-97) to examine predictors of experiencing homelessness as a young adult (before age 25). The NLSY-97 includes a nationally representative sample of 8,984 youth. Data were first collected from these youth when they were between the ages of 12 to 18 years. The current study examined whether individual and family risk factors reported during adolescence predict homelessness by the age of 25. The findings showed …

Characteristics Of Mothers Caring For Children During Episodes Of Homelessness, Melissa L. Welch-Lazoritz, Les B. Whitbeck, Brian E. Armenta

Department of Sociology: Faculty Publications

This study provides a description of the physical, psychological, and substance use problems of adult homeless women who are and are not caring for children. We also examined differences in the characteristics of these two groups of women. Interviews were conducted with 148 homeless women from three mid-sized U.S. cities, 24.3% of whom were caring for at least one child. Our results showed that women caring for children were more likely to be sheltered and have health insurance. Homeless women caring for children and solitary homeless women were generally similar in terms of substance abuse problems. However, rates of Borderline …

Hiv/Aids In Puerto Rican People Who Inject Drugs: Policy Considerations, Luz M. López, Lisa De Saxe Zerden, Philippe Bourgois, Helena Hansen, Roberto Abadie, Kirk Dombrowski, Ric Curtis

Department of Sociology: Faculty Publications

We commend the important work of Deren et al. that underscores the high rates of HIV among Puerto Rican people who inject drugs (PRPWID) and highlights the health, social, and service disparities between Puerto Rico and the Northeast US region. As articulated in their article, HIV/AIDS risk and substance use are not individual problems with individual consequences—the epidemic impacts community and culture, across borders and boundaries. In addition to service disparities, various socioeconomic contextual factors are associated with and may exacerbate the spread of HIV/AIDS in PRPWID, including limited educational and employment opportunities, poverty, and political disenfranchisement. Efforts to reduce …

Methylenedioxypyrovalerone (Mdpv) Mimics Cocaine In Its Physiological And Behavioral Effects But Induces Distinct Changes In Nac Glucose, Ken T. Wakabayashi, Suelynn E. Ren, Eugene A. Kiyatkin

Department of Psychology: Faculty Publications

Methylenedioxypyrovalerone (MDPV) is generally considered to be a more potent cocaine-like psychostimulant, as it shares a similar pharmacological profile with cocaine and induces similar physiological and locomotor responses. Recently, we showed that intravenous cocaine induces rapid rise in nucleus accumbens (NAc) glucose and established its relation to neural activation triggered by the peripheral drug actions. This study was conducted to find out whether MDPV, at a behaviorally equivalent dose, shares a similar pattern of NAc glucose dynamics. Using enzyme-based glucose sensors coupled with amperometery in freely moving rats, we found that MDPV tonically decreases NAc glucose levels, a response that …

Do Dimensions Of Ethnic Identity Mediate The Association Between Perceived Ethnic Group Discrimination And Depressive Symptoms?, Aerika S. Brittian, Su Yeong Kim, Brian E. Armenta, Richard M. Lee, Adriana J. Umaña-Taylor, Seth J. Schwartz, Ian K. Villalta, Byron L. Zamboanga, Robert S. Weisskirch, Linda P. Juang, Linda G. Castillo, Monika L. Hudson

Department of Psychology: Faculty Publications

Ethnic group discrimination represents a notable risk factor that may contribute to mental health problems among ethnic minority college students. However, cultural resources (e.g., ethnic identity) may promote psychological adjustment in the context of group-based discriminatory experiences. In the current study, we examined the associations between perceptions of ethnic group discrimination and depressive symptoms, and explored dimensions of ethnic identity (i.e., exploration, resolution, and affirmation) as mediators of this process among 2,315 ethnic minority college students (age 18 to 30 years; 37% Black, 63% Latino). Results indicated that perceived ethnic group discrimination was associated positively with depressive symptoms among students …

Estimating Vertex Measures In Social Networks By Sampling Completions Of Rds Trees, Bilal Khan, Kirk Dombrowski, Ric Curtis, Travis Wendel

Department of Sociology: Faculty Publications

This paper presents a new method for obtaining network properties from incomplete data sets. Problems associated with missing data represent well-known stumbling blocks in Social Network Analysis. The method of “estimating connectivity from spanning tree completions” (ECSTC) is specifically designed to address situations where only spanning tree(s) of a network are known, such as those obtained through respondent driven sampling (RDS). Using repeated random completions derived from degree information, this method forgoes the usual step of trying to obtain final edge or vertex rosters, and instead aims to estimate network-centric properties of vertices probabilistically from the spanning trees themselves. In …

Museum Monsters And Victorious Viruses: Improving Public Understanding Of Emerging Biomedical Research, Judy Diamond, Benjamin Jee, Camilla Matuk, Julia Mcquillan, Amy N. Spiegel, David Uttal

Department of Sociology: Faculty Publications

Although microbes directly impact everyone's health, most people have limited knowledge about them. In this article, we describe a museum and media public education campaign aimed at helping diverse audiences better understand emerging knowledge about microbes and infectious disease. Funded primarily by the Science Education Partnership (SEPA) program of the National Institutes of Health, this campaign involved crosscutting programs designed to extend impacts throughout a broad public audience.
