Chronic Stress Elevates Telomerase Activity In Rats, Annaliese K. Beery, Jue Lin, Joshua S. Biddle, Darlene D. Francis, Elizabeth H. Blackburn, Elissa S. Epel

Neuroscience: Faculty Publications

The enzyme telomerase lengthens telomeres—protective structures containing repetitive DNA sequences at chromosome ends. Telomere shortening is associated with diseases of ageing in mammals. Chronic stress has been related to shorter immune-cell telomeres, but telomerase activity under stress may be low, permitting telomere loss, or high, partially attenuating it. We developed an experimental model to examine the impacts of extended unpredictable stress on telomerase activity in male rats. Telomerase activity was 54 per cent higher in stressed rats than in controls, and associated with stress-related physiological and behavioural outcomes. This significant increase suggests a potential mechanism for resilience to stress-related replicative …

Perceptions Of Peer Leadership Among Honors Students, Christy M. Culbreth

Mahurin Honors College Capstone Experience/Thesis Projects

My Capstone Experience/Thesis project seeks to explore and compare the perceptions of peer leadership among freshmen honors students who have received formal leadership training and freshmen honors students who have received no formal leadership training. Peer leadership plays an important role in all aspects of life. If students who have had formal leadership training have a more positive perception of their peer leaders, educators may want to put more peer leadership curriculum into their programs. This study tests the hypothesis that freshmen honors students who have received formal leadership training will have a more positive perception of their peer leaders. …

Neuroanatomical Substrates Of The Disruptive Effect Of Olanzapine On Rat Maternal Behavior As Revealed By C-Fos Immunoreactivity, Changjiu Zhao, Ming Li

Department of Psychology: Faculty Publications

Olanzapine is one of the most widely prescribed atypical antipsychotic drugs in the treatment of schizophrenia. Besides its well-known side effect on weight gain, it may also impair human parental behavior. In this study, we took a preclinical approach to examine the behavioral effects of olanzapine on rat maternal behavior and investigated the associated neural basis using the c-Fos immunohistochemistry. On postpartum Days 6–8, Sprague-Dawley mother rats were given a single injection of sterile water or olanzapine (1.0, 3.0 or 5.0 mg/kg, sc). Maternal behavior was tested 2 h later, after which rats were sacrificed and brain tissues were collected. …

The Effect Of Weight Loss On Changes In Health-Related Quality Of Life Among Overweight And Obese Women With Urinary Incontinence, Angela Marinilli Pinto, Leslee L. Subak, Sanae Nakagawa, Eric Vittinghoff, Rena R. Wing, John W. Kusek, William H. Herman, Delia Smith West, Miriam Kuppermann

Publications and Research

OBJECTIVE: To estimate the effect of change in weight and change in urinary incontinence (UI) frequency on changes in preference-based measures of health-related quality of life (HRQL) among overweight and obese women with UI participating in a weight loss trial.

METHODS: We conducted a longitudinal cohort analysis of 338 overweight and obese women with UI enrolled in a randomized clinical trial comparing a behavioral weight loss intervention to an educational control condition. At baseline, 6, and 18 months, health utilities were estimated using the Health Utilities Index Mark 3 (HUI3), a transformation of the SF-36 to the preference-based SF-6D, and …

Transforming The Healthcare Response To Intimate Partner Violence And Taking Best Practices To Scale, Michele R. Decker, Shannon Frattaroli, Brigid Mccaw, Ann L. Coker, Elizabeth Miller, Phyllis Sharps, Wendy G. Lane, Mahua Mandal, Kelli Hirsch, Donna M. Strobino, Wendy L. Bennett, Jacquelyn Campbell, Andrea Gielen

CRVAW Faculty Journal Articles

BACKGROUND: Intimate partner violence (IPV) is prevalent among adolescent and adult women, with significant physical, sexual, and mental health consequences. In 2011, the Institute of Medicine's Clinical Preventive Services for Women consensus report recommended universal screening for violence as a component of women's preventive services; this policy has been adopted by the Health Resources and Services Administration (HRSA). These policy developments require that effective clinic-based interventions be identified, easily implemented, and taken to scale.

METHODS: To foster dialogue about implementing effective interventions, we convened a symposium entitled "Responding to Violence Against Women: Emerging Evidence, Implementation Science, and Innovative Interventions," on …

Brooding Deficits In Memory: Focusing Attention Improves Subsequent Recall, Paula T. Hertel, Amanda A. Benbow, E. Geraerts

Psychology Faculty Research

Ruminative habits of thought about one’s problems and the resulting consequences are correlated with symptoms of depression and cognitive biases (Nolen-Hoeksema, Wisco, & Lyubomirsky, 2008). In our orienting task, brooders and nonbrooders concentrated on self-focusing phrases while they were also exposed to neutral target words. On each trial in the unfocused condition, participants saw and then reported the target before concentrating on the phrase; in the focused condition, the target was reported after phrase concentration. A brooding-related deficit on a subsequent unexpected test of free and forced recall was obtained in the unfocused condition only. Brooders recalled more successfully in …

Interpersonal Counterproductive Work Behaviors: Distinguishing Between Person-Focused Versus Task-Focused Behaviors And Their Antecedents, Violet Ho

Management Faculty Publications

Purpose – This study proposes a nuanced perspective for conceptualizing interpersonal counterproductive work behaviors (ICWBs) by distinguishing them into behaviors that hinder other workers’ task performance (task-focused ICWBs), and those that are personal in nature (person-focused ICWBs). A relational stress perspective is adopted to examine work-based dependence relational stressor and negative-affect relational stressor as predictors of each category of behavior, with trait competitiveness as a moderator.

Design/methodology/approach – Deductive and inductive approaches were used to generate items measuring each type of ICWBs, and the two-factor ICWB structure was validated using data from 136 respondents. Data from a different sample of …

Which Study Method Works Best? A Comparison Of Soar And Sq3r For Text Learning, Sarah C. Kasson

College of Education and Human Sciences: Dissertations, Theses, and Student Research

One hundred thirty-eight college students participated in a study comparing the SOAR (Select, Organize, Association, Regulate) and SQ3R (Survey, Question, Read, Recite, Review) study systems to each other and to students’ preferred study methods. Though both systems have been researched independently, just one other study has compared these study systems to each other. College students were assigned randomly to one cell of a 2x2 factorial design (method: SOAR or SQ3R; material: supplement or no supplement) or to a preferred-study-method control group. Groups were trained in their respective system (SOAR, SQ3R, or control) and then given materials about educational measurement to …

The Social Psychology Of Perception Experiments: Hills, Backpacks, Glucose, And The Problem Of Generalizability, Frank H. Durgin, Brennan James Klein , '14, Ariana Michelle Spiegel , '13, Cassandra Joy Strawser , '13, Morgan James Christopher Williams , '14

Psychology Faculty Works

Experiments take place in a physical environment but also a social environment. Generalizability from experimental manipulations to more typical contexts may be limited by violations of ecological validity with respect to either the physical or the social environment. A replication and extension of a recent study (a blood glucose manipulation) was conducted to investigate the effects of experimental demand (a social artifact) on participant behaviors judging the geographical slant of a large-scale outdoor hill. Three different assessments of experimental demand indicate that even when the physical environment is naturalistic, and the goal of the main experimental manipulation was primarily concealed, …

Being Active And Impulsive: The Role Of Goals For Action And Inaction In Self-Control, Justin Hepler, Dolores Albarracin, Kathleen C. Mcculloch, Kenji Noguchi

Faculty Publications

Although self-control often requires behavioral inaction (i.e., not eating a piece of cake), the process of inhibiting impulsive behavior is commonly characterized as cognitively active (i.e., actively exerting self-control). Two experiments examined whether motivation for action or inaction facilitates self-control behavior in the presence of tempting stimuli. Experiment 1 used a delay discounting task to assess the ability to delay gratification with respect to money. Experiment 2 used a Go/No-Go task to assess the ability to inhibit a dominant but incorrect motor response to the words "condom" and "sex". The results demonstrate that goals for inaction promote self-control, whereas goals …

Experiencing Sexism And Young Women's Body Esteem, Debra Oswald, Stephen L. Franzoi, Katherine Frost

Psychology Faculty Research and Publications

This two-study investigation examined the relationship between sexist attitudes and experiences with young women’s body esteem. Specifically, we examined whether young women's body esteem was related to their own and their parents' endorsements of benevolent and hostile sexist beliefs and also whether women’s body esteem was related to their actual everyday experiences with benevolent and hostile sexism. In Study 1, fathers' endorsement of benevolently sexist beliefs was positively correlated with daughters' weight-related and physical condition body esteem. No similar evidence was found for mothers or for either parent's endorsements of hostile sexist beliefs. In Study 2, young women’s body esteem …

Spectrum Of Acute Clinical Characteristics Of Diagnosed Concussions In College Athletes Wearing Instrumented Helmets, Ann-Christine Duhaime,, Jonathan G. Beckwith, Arthur C. Maerlender, Thomas W. Mcallister, Joseph J. Crisco, Stefan M. Duma, P. Gunnar Brolinson, Steven Rowson, Laura A. Flashman, Jeffrey J. Chu, Richard M. Greenwald

Department of Psychology: Faculty Publications

Object. Concussive head injuries have received much attention in the medical and public arenas, as concerns have been raised about the potential shortand long-term consequences of injuries sustained in sports and other activities. While many student athletes have required evaluation after concussion, the exact definition of concussion has varied among disciplines and over time. The authors used data gathered as part of a multiinstitutional longitudinal study of the biomechanics of head impacts in helmeted collegiate athletes to characterize what signs, symptoms, and clinical histories were used to designate players as having sustained concussions.

Methods. Players on 3 college …

Perfectionism: The Good, The Bad, And The Creative, Benjamin Wigert, Roni Reiter-Palmon, James C. Kaufman, Paul J. Silvia

Psychology Faculty Publications

The influence of adaptive and maladaptive perfectionism on creativity was examined. Initially, six measures of creativity were administered, including creative self-perceptions, behavior, and performance measures. Adaptive perfectionism was weakly positively related to creativity, whereas maladaptive perfectionism was unrelated to creativity across five of the six measures. A follow-up study assessed whether initial findings could be generalized to an everyday problem-solving task. Results indicated that adaptive perfectionism was related to higher quality but not originality of solutions. Further, a curvilinear relationship in the shape of an inverted “U” occurred between adaptive perfectionism and four of eight creativity measures. Overall, adaptive perfectionism …

Attentional Biases To Foods: The Effects Of Caloric Content And Cognitive Restraint, Catherine A. Forestell, Pia Lau, Ivo I. Gyurovski, Cheryl L. Dickter, Sabrina S. Haque

Arts & Sciences Articles

The goal of the present study was to determine whether female restrained and unrestrained eaters demonstrated differential levels of attentional bias to high calorie foods when they were presented as distractors in a flanker task. This task consisted of four blocks of 68 trials in which three food pictures were briefly presented simultaneously on a computer screen. On each trial a high or low calorie target food was presented in the center of a pair of high or low calorie food flanker pictures and participants’ reaction times to answer a basic question about whether they would consume the target food …

Age Differences In Reward Anticipation And Memory, Kristen L. Cushman

Masters Theses & Specialist Projects

Aging research on item- and associative-recognition memory has demonstrated that older adults are deficient in forming associations between two unrelated stimuli. Although older adult performance on tests of item-recognition is similar to younger adult performance, older adults perform worse than younger adults on tests of associative memory (Naveh-Benjamin, Hussain, Guez, & Bar-On, 2003). In addition to the idea that younger adult performance on associative-recognition tests is superior to that of older adults, research has shown that reward cues can enhance motivated learning and item memory performance of younger adults. In an fMRI study that examined the influence of reward anticipation …

The Relationship Between Eating Disorder Symptomology, Critical Body Comments, And Memory Recall, Morgan Littrell

Masters Theses & Specialist Projects

Previous research done in the area of eating disorders suggests many different variables, such as cognitive, biological, and social, that are thought to influence eating disorder development and maintenance. The present study attempts to combine cognitive and sociocultural research findings, memory recall and critical body comments, in an effort to see how, if at all, these two variables affect eating disorder symptomology. Participants for this study were 120 female students that were recruited via Study Board. Participants completed the demographics form, the Eating Disorder Inventory-3 RF, and the Social Hassles Questionnaire. The participants then watched an E-prime presentation of different …

Validity Evidence For The Situational Judgment Test Paradigm In Emotional Intelligence Measurement, Nele Libbrecht, Filip Lievens

Research Collection Lee Kong Chian School Of Business

To date, various measurement approaches have been proposed to assess emotional intelligence (EI). Recently, two new EI tests have been developed based on the situational judgment test (SJT) paradigm: the Situational Test of Emotional Understanding (STEU) and the Situational Test of Emotion Management (STEM). Initial attempts have been made to examine the construct-related validity of these new tests; we extend these findings by placing the tests in a broad nomological network. To this end, 850 undergraduate students completed a personality inventory, a cognitive ability test, a self-report EI test, a performance-based EI measure, the STEU, and the STEM. The SJT-based …

BackgroundInfection with HIV may result in significant neuropsychological impairment, especially in late stage disease. To date, there have been no cohort studies of the impact of highly active anti-retroviral treatment (HAART) in South Africa where clade C HIV is predominant.MethodsParticipants in the current study were recruited from a larger study of HIV-associated neurocognitive disorders (HAND) and included a group of individuals commencing HAART (n = 82). Baseline and one-year neuropsychological function was assessed using a detailed battery, and summary global deficit scores (GDS) obtained. Associations with change in GDS were calculated.ResultsParticipants had a median CD4 cell count of 166 at …

Cortical Thickness In Neuropsychologically Near-Normal Schizophrenia, Derin J. Cobia, John G. Csernansky, Lei Wang

Faculty Publications

Schizophrenia is a chronic and potentially disabling disorder with widespread neuroanatomical abnormalities thought to be caused by progressive brain changes (Andreasen, 2010), and an equally wide variety of impairments in cognitive functioning (Palmer et al., 2009). In general, individuals with schizophrenia demonstrate significantly impaired performance on a full range of neuropsychological tasks, often reaching greater than one standard deviation below the norm (Dickinson et al., 2007). One particularly puzzling issue is that approximately 15–30% of schizophrenia patients have been found to perform in the normal range of neuropsychological functioning (Kremen et al., 2000; Palmer et al., 1997). Given hypothesized relationships …

Are All Older Adult Transgressors Treated Equally?, Heather Marie Dahlgren

Masters Theses & Specialist Projects

Research has shown that young adults treat older adults with less blame and more forgiveness when they commit a social transgression. This study sought to understand whether the stereotype of an assumed positive personality and/or a supposed lack of cognitive ability are potential driving forces behind the greater leniency that young adults display toward older transgressors. Seventy-five young adult participants were randomly assigned to one of five experimental conditions. Participants’ aging stereotypes were primed with one of four paragraphs that depicted older adults as (a) socially warm and cognitively competent, (b) socially cold but cognitively competent, (c) socially warm but …

Examining Crime Among College-Aged Christians: Are Christian Religious Beliefs Associated With Low Levels Of Criminal Activity?, Paul Rickert

Doctoral Dissertations and Projects

The purpose of this correlational study into crime among college-aged Christians in the United States is to determine if indicating higher levels of Christian spiritual growth is associated with lower levels of criminal behavior. A convenience sample of college aged Christians was given an online survey to measure self-reported criminality measured by the United States Federal Bureau of Investigation (FBI) Uniform Crime Reports Part I and Part II and self-reported religious convictions as measured by Bufford et al.'s Christ-like Spiritual Growth Scale. This quantitative study then analyzed data generated from 57 respondents and found that reporting higher rates of Christ-like …

The Legal Significance Of The Psychological Ability To Appreciate The “Other”, Paul F. Rothstein

Georgetown Law Faculty Publications and Other Works

Recently the U.S. Supreme Court, citing neurological and psychological studies, held that because juveniles are deficient in appreciating consequences to others, they should never be given the death penalty. The author found, in his years as a legal scholar, educator, and practitioner, that “appreciating the ‘other’”--putting oneself in the position of others---is critical to law and the study of law in more than the obvious ways.

The author became aware of empirical studies and psychological experiments demonstrating that children below a certain age have trouble seeing things from another’s vantage point, and found that the facility to do so develops …

The Serotonin Transporter Gene Linked Polymorphic Region Is Associated With The Behavioral Response To Repeated Stress Exposure In Infant Rhesus Macaques, Simona Spinelli, Melanie L. Schwandt, Stephen G. Lindell, Markus Heilig, Stephen J. Suomi, James Dee Higley, David Goldman, Christina S. Barr

Faculty Publications

The short allele of the serotonin transporter linked polymorphic region (5-HTTLPR) moderates the effects of stress on vulnerability to mood and anxiety disorders. The mechanism by which this occurs may relate to differential sensitivity to stressful life events. Here we explored whether 5- HTTLPR and sex affected behavioral responses to repeated maternal separation in infant rhesus macaques. Behaviors were collected during the acute (Day 1) and the chronic (Days 2–4) phases of the separation, and the effects of duration of separation (acute vs. chronic), genotype (long/long vs. short allele), and sex (male vs. female) on behavioral responses were analyzed across …

Professional Deceit: Normal Lying In An Occupational Setting, Janet M. Ruane, Karen Cerulo

Department of Sociology Faculty Scholarship and Creative Works

Normal lies are those that social actors legitimate as appropriate means to desirable outcomes. Such lies have been acknowledged in the literature as tools for maintaining social order. Yet, little has been done to document the social structural sources of normal lying. This paper offers a first step in filling this research gap, examining aspects of occupational structure and their connection to the practice of normal lying. Specifically, we discuss four dimensions of occupational structure — occupational rewards and entry requirements, occupational loyalties, social control styles within an occupation, and an occupation's level of professionalization — and we explore the …

The Efficacy Of Vigorous-Intensity Exercise As An Aid To Smoking Cessation In Adults With Elevated Anxiety Sensitivity: Study Protocol For A Randomized Controlled Trial, Jasper Aj Smits, Michael J. Slovensky, David Rosenfield, Bess H. Marcus, Timothy S. Church, Georita M. Frierson, Mark B. Powers, Michael W. Otto, Michelle L. Davis, Lindsey B. Deboer, Nicole F. Briceno

Faculty Scholarship for the College of Science & Mathematics

Background: Although cigarette smoking is a leading cause of death and disability in the United States (US), over 40 million adults in the US currently smoke. Quitting smoking is particularly difficult for smokers with certain types of psychological vulnerability. Researchers have frequently called attention to the relation between smoking and anxiety-related states and disorders, and evidence suggests that panic and related anxiety vulnerability factors, specifically anxiety sensitivity (AS or fear of somatic arousal), negatively impact cessation. Accordingly, there is merit to targeting AS among smokers to improve cessation outcome. Aerobic exercise has emerged as a promising aid for smoking …

Salivary Cortisol And Interpersonal Functioning: An Event-Contingent Recording Study In The Offspring Of Parents With Bipolar Disorder, Mark A. Ellenbogen, Anne-Marie Linnen, Jonathan Bruce Santo, Marije Aan Het Rot, Sheilagh Hodgins, Simon N. Young

Psychology Faculty Publications

Despite a large body of research in non-human primates, the relationship between naturalistic patterns of social behaviour and basal cortisol levels has been understudied in humans. The present study examined the relationship between patterns of interpersonal functioning and cortisol levels in 23 offspring of parents with bipolar disorder (BD), at high risk for the development of an affective disorder, and 22 offspring of parents with no affective disorder (controls) in late adolescence and young adulthood. Using event-contingent recording, participants rated their dominance, submissiveness, quarrelsomeness, and agreeableness in naturally occurring social interactions over 14 consecutive days and provided salivary cortisol twice …
