Normative Violence? The Impact Of Gender-Neutral Language On Self-Reported Rates Of Sexual Violence Victimization And Perpetration, Elizabeth Ruth Anthony

Psychology Theses

The effect of gender-neutral language in a survey designed to measure unwanted sexual experiences was examined. Methodological issues pertaining to survey design and significant variability in prevalence estimates of sexual violence demonstrate that further refinement of self-report instruments is necessary. As a variety of macrolevel forces influence individual behavior, the current study contends that coercive tactics used to obtain sex in mixed-gender interactions are normalized by the traditional heterosex script and conveyed through gender-specific language. Reference to respondents’ sexual partners in gender-neutral, as opposed to gender-specific terms, was hypothesized to result in more disclosure of sexually coercive victimization and perpetration …

An Ecological Model Of Academic Negative Prediction Defiance In College Students, Kelly L. Maltese Tsai

Psychology Dissertations

Pathways to becoming a college student are as numbered and varied as college students themselves. For some people, the pathway to college is marked by barriers, such as negative messages received by the student regarding their abilities to attend college and/or the likelihood that they will get to attend college. On one hand, research suggests that children and adolescents internalize these negative messages, which then have the potential to block achievement in higher education. On the other hand, the general body of resilience research suggests that youth can overcome challenges and defy negative influences, as did the participants of the …

Rumination As A Mediator Of The Relation Between Mindfulness And Social Anxiety In A Clinical Sample, Stefan K. Schmertz

Psychology Dissertations

Recent literature has emphasized the possible benefits to mindfulness practice. Evidence for a negative relation between mindfulness and pathology has come from validity studies of several newly developed, self-report mindfulness questionnaires. Results illustrate a consistent negative relation between levels of self-report mindfulness and symptoms of depression, negative affect, and anxiety among college-student samples, however this relation has been previously untested within a clinical sample. The first aim of the present study was to explore the relation between mindfulness levels and social anxiety symptoms in a clinical sample diagnosed with social phobia. Because past research has found mindfulness interventions to be …

Sex Differences In Morphine Analgesia And The Descending Modulation Of Pain, Dayna Ruth Loyd

Psychology Dissertations

Morphine is the most widely prescribed opiate for alleviation of persistent pain; however, it is becoming increasingly clear that morphine is less potent in women compared to men. Morphine primarily binds mu opioid receptors, which are densely localized in the midbrain periaqueductal gray (PAG). Anatomical and physiological studies conducted in the 1960s identified the PAG, and its projections to the rostral ventromedial medulla (RVM) and spinal cord dorsal horn, as an essential neural circuit mediating opioid-based analgesia. Remarkably, the majority of studies since then were conducted in males with the implicit assumption that this circuit was the same in females; …

Rapid Automatized Naming And Reading Ability, Rebecca Eisenberg Mccartney

Psychology Dissertations

The Rapid Automatized Naming test (RAN) has been shown to be a strong predictor of reading ability (Katzir et al., 2006), however the nature of this relationship remains unclear. The purpose of this study was to evaluate the underlying components of RAN, and to then determine whether these components partially account for the relationship between RAN and reading ability. The sample consisted of 100 undergraduate students. The underlying components of RAN that were evaluated included, visual search and scanning, auditory and visual sequencing, discrete naming, confrontation naming, executive functioning and phonological processing. The findings suggest that visual search and scanning, …

Exposure To Gambling-Related Media And Its Relation To Gambling Expectancies And Behaviors, Leanne Valentine

Psychology Dissertations

Today’s youth have been exposed to more gambling-related media than previous generations, and they have grown up in an era in which states not only sanction but also run and promote gambling enterprises. Social Learning Theory proposes that one can develop new attitudes or expectancies about a specific behavior by watching others engage in that behavior, and that the media is one avenue through which one can develop new expectancies (Bandura, 2001). In addition, the Theory of Reasoned Action proposes that one’s behaviors are influenced directly by both subjective norms and attitudes (Fishbein and Ajzen, 1975). A mixed methods explanatory …

"Getting Better" After Torture From The Perspective Of The Survivor, Brian Louis Isakson

Psychology Dissertations

The traditional model of Western mental health treatment for survivors of torture has focused mainly on posttraumatic stress disorder and related conditions. This model is symptoms-focused in which the goal is to reduce pathology. In this model, the mental health professional is the expert and the survivors learn from the professionals. Using grounded theory methodology, the current study seeks to expand the understanding for treatment of torture survivors by investigating, from the perspective of the torture survivors, the process of “getting better” after torture. By asking the survivors to explain this process, this study broadens the focus of areas of …

Numerical Cognition In Rhesus Monkeys (Macaca Mulatta), Emily Harris Marr

Psychology Dissertations

Over the past few decades, researchers have firmly established that a wide range of nonhuman animals exhibit some form of numerical competence. The focus of this research was to define further the extent of numerical ability in rhesus monkeys, and specifically to determine whether the animals possess a symbolic understanding of Arabic numerals. This required examining the stimulus attributes (e.g., number vs. hedonic value) represented by the numerals, as well as the precision (e.g., absolute vs. relative) and generality of those representations. In chapters 2 and 3, monkeys were required to compare and order numerals and were rewarded with either …

Strong Black Woman Cultural Construct: Revision And Validation, Dhakirah Amelia Hamin

Psychology Dissertations

The purpose of the current study is to revise the wording of the items in the Strong Black Woman (SBW) attitudes scale and investigate the psychometric properties of this revised scale (renamed the SBW Cultural Construct Scale, SBWCCS). Another goal is to determine if the scale predicts racial identity, stress, and social support. The sample consisted of 152 women of African descent, who were recruited from a community based organization. An exploratory factor analysis on the SBWCCS scale suggested a 3-factor model consisting of (1) caretaking, (2) affect regulation, and (3) self-reliance. These factors parallel those found in the original …

Fidelity-Outcomes Relationships In The Expect Respect Program, Angela Devi Mooss

Psychology Theses

The effects of program fidelity, gender, socioeconomic status, and school level were tested on various outcomes of a dating violence prevention program, Expect Respect. Fidelity data was collected from program facilitators, and individual posttest scores were gathered for individuals nested within each programmatic site. Multiple HLM models indicated that main effects for fidelity were present for the knowledge gained outcome scale, such that higher program fidelity led to higher posttest scores for participants. No other site level predictors affected outcomes or the fidelity-outcome relationship. Results from this study point towards the importance of implementing program fidelity when cognitive gains are …

The Association Between Social Context And Phase Of Recovery Among Drug Court Clients: A Gender Comparison, Jennifer Lee Zorland

Psychology Theses

The association between drug court clients’ pro-drug and pro-recovery social context at multiple ecological levels, and phase of recovery was assessed, and gender comparisons were evaluated. Drug courts provide alternatives to incarceration for substance abusing offenders, providing treatment within clients’ social environments. The findings indicated that social context is associated with recovery, and that this relation differs by gender. Specifically, increased favorable attitudes toward drug use among social referents were associated with men being in an earlier phase of recovery and women being in a later phase of recovery. Furthermore, perceived encouragement to use drugs was associated with being in …

The Role Of Gabaergic Transmission In Mediation Of Striatal Local Field Potentials (Lfps), Andrew R. Seiscio

Psychology Theses

In the present study, electrophysiological and behavioral effects of compromised Gama-Aminobutyric Acid (GABAergic) transmission were investigated in adult Rhesus macaque monkeys (N=2). GABAergic transmission was perturbed in the putamen by administration of a GABAa receptor antagonist, gabazine (10 and 500 μM), via a microdialysis-local field potential (MD-LFP) probe. Resultant changes in striatal local field potentials (LFPs) were measured as an assay of synchrony. Gabazine perfusion evoked discrete large amplitude spikes in LFPs in all subjects, and the frequency and shape of individual spikes were concentration-dependent. Pre-treatment with the GABAa receptor agonist, muscimol (100 μM) blocked the gabazine-induced events, confirming a …

Relationships Between Religion And Prejudice: Implicit And Explicit Measures., Horace Ted Denney

Psychology Theses

This study examined the relationship among implicit and explicit measures of prejudice (against African-Americans, homosexuals, and Muslims), Right-Wing Authoritarianism (RWA), Religious Fundamentalism (RF), and Christian Orthodoxy (CO). The implicit measure of prejudice was Facial EMG, which is the measurement of the activity of key facial muscles when participants were exposed to pictures of members of the minority groups, as well as to pictures of the corresponding group. The explicit measure of prejudice was the Social Distance Scale, which measures how willing people are to have someone in a variety of close relationships. The primary hypothesis was that one’s score on …

The Relationship Between Executive Functions And Metacognitive Strategy Learning And Application, Eva Mashock Jansiewicz

Psychology Dissertations

This project examined whether the executive functions of set maintenance and switching, as assessed by neuropsychological testing, were predictors of set maintenance and switching within a more ecologically valid task that used metacognitive strategies during reading comprehension tasks as a framework for evaluation. Gaze times to key words during reading were used as an indirect measure of strategy use. A few significant relationships were found between set maintenance and set switching on the neuropsychological measures and the strategy learning and application tasks. Participants were more likely to switch to appropriate strategies in a situation in which they were given free …

College Men's Psychological And Physiological Responses Associated With Violent Video Game Play, Cecil Lamonte Powell

Psychology Dissertations

Research suggests that playing violent video games increases the likelihood of aggression. However, less clear is how individual characteristics influence the mechanisms that lead to aggression. Using Anderson and Bushman’s (2002) General Aggression Model as a framework, the present study examined the independent and joint effects of individual differences and situational factors on affective and physiological reactivity to playing a violent video game. One hundred thirty-three participants completed self-report measures of trait aggression and violent video game exposure. They were randomly assigned to groups instructed to play a video game using either violent or nonviolent strategies while facial electromyography, heart …

Neurocircuitry And Molecular Basis Of Conditioned Defeat In Male Syrian Hamsters, Stacie Lin Taylor

Psychology Dissertations

Stress affects virtually all organisms and can result in both physiological and behavioral changes. Conditioned defeat in Syrian hamsters is a model of stress-induced behavioral plasticity that occurs in a social context. In this model, hamsters are defeated by a larger, more aggressive counterpart. Defeated hamsters subsequently fail to defend their own territory and show striking and long-lasting increases in submissive behavior even when paired with a non-threatening counterpart. The present series of experiments seeks to identify the brain regions and molecular mediators that contribute to this behavioral plasticity. One brain region that has been overlooked by our laboratory is …

Effects Of A High Fructose Diet On Physiology And Cognition In Male Sprague-Dawley Rats, Amy Patricia Ross

Psychology Theses

Fructose consumption has increased exponentially during the past four decades. The physiological effects of a high fructose diet include obesity and insulin resistance. In animal models, the effects of a high fructose diet on fat distribution are inconclusive in that some studies find increases in body mass and lipids while others find no effect. Recent findings indicate that a high fructose diet causes hippocampal insulin resistance in hamsters, raising the possibility that the diet causes impairments in cognition. The following experiments tested the hypotheses that a high fructose diet alters fat distribution rather than total body mass and impairs hippocampal-dependent …

Discrimination Reversal Learning In Capuchin Monkeys (Cebus Apella), Michael J. Beran, Emily D. Klein, Theodore A. Evans, Betty Chan, Timothy M. Flemming, Emily H. Harris, David A. Washburn, Duane M. Rumbaugh

Language Research Center

Learning styles in capuchin monkeys were assessed with a computerized reversal- learning task called the mediationaJ paradigm. First, monkeys were trained to respond with 90% accuracy on a two-choice discrimination (A+B-). Then the authors examined differences in performance on three different types of reversal trials (A-B+, A-C+, B+C-), each of which offered differing predictions for performance, depending on whether the monkeys were using associative cues or rule-based strategies. Performance indicated that the monkeys mainly learned to avoid the B stimulus during training, as the A-C+ condition produced the best performance levels. Therefore, negative stimuli showed greater control over responding after …

Age And Body Satisfaction Predict Diet Adherence In Adolescents With Inflammatory Bowel Disease, Christina H. Vlahou, Lindsey L. Cohen, Amanda M. Woods, Jeffrey D. Lewis, Benjamin D. Gold

Psychology Faculty Publications

The aim of the current study was to determine whether age and body satisfaction predict dietary adherence in adolescents with Inflammatory Bowel Disease (IBD), and whether older females are less adherent than younger males and females. Forty-four participants aged 10-21 with IBD were recruited. Participants provided informed consent and demographics. Body satisfaction was measured by a questionnaire and a task in which participants selected their current and ideal body image out of silhouettes depicting bodies ranging from underweight to obese. Adherence was measured by marking a 100mm visual analog scale, the 1-week completion of a dietary log, and a questionnaire …

Chimpanzee Autarky, Sarah F. Brosnan, Mark F. Grady, Susan P. Lambeth, Steven J. Schapiro, Michael J. Beran

Psychology Faculty Publications

Background: Economists believe that barter is the ultimate cause of social wealth—and even much of our human culture—yet little is known about the evolution and development of such behavior. It is useful to examine the circumstances under which other species will or will not barter to more fully understand the phenomenon. Chimpanzees (Pan troglodytes) are an interesting test case as they are an intelligent species, closely related to humans, and known to participate in reciprocal interactions and token economies with humans, yet they have not spontaneously developed costly barter.

Methodology/Principle Findings: Although chimpanzees do engage in noncostly barter, …

A Developmental Examination Of Amygdala Response To Facial Expressions, Amanda E. Guyer, Christopher S. Monk, Erin Tone, Eric E. Nelson, Roxann Roberson-Nay, Abby D. Adler, Stephen J. Fromm, Ellen Leibenluft, Daniel S. Pine, Monique Ernst

Psychology Faculty Publications

Several lines of evidence implicate the amygdala in face-emotion processing, particularly for fearful facial expressions. Related findings suggest that face-emotion processing engages the amygdala within an interconnected circuitry that can be studied using a functional-connectivity approach. Past work also underscores important functional changes in the amygdala during development. Taken together, prior research on amygdala function and development reveals a need for more work examining developmental changes in the amygdala’s response to fearful faces and in amygdala functional connectivity during face processing. The present study used event-related functional magnetic resonance imaging to compare 31 adolescents (9–17 years old) and 30 adults …

Recognition Of Facial Emotions Among Maltreated Children With High Rates Of Post–Traumatic Stress Disorder, Carrie L. Masten, Amanda E. Guyer, Hilary B. Hodgdon, Erin B. Mcclure, Dennis S. Charney, Monique Ernst, Joan Kaufman, Daniel S. Pine, Christopher S. Monk

Psychology Faculty Publications

Objective. The purpose of this study is to examine processing of facial emotions in a sample of maltreated children showing high rates of post-traumatic stress disorder (PTSD). Maltreatment during childhood has been associated independently with both atypical processing of emotion and the development of PTSD. However, research has provided little evidence indicating how high rates of PTSD might relate to maltreated children’s processing of emotions. Method. Participants’ reaction time and labeling of emotions were measured using a morphed facial emotion identification task. Participants included a diverse sample of maltreated children with and without PTSD and controls ranging in age from …

Amygdala And Ventrolateral Prefrontal Cortex Function During Anticipated Peer Evaluation In Pediatric Social Anxiety, Amanda E. Guyer, Jennifer Y. Lau, Erin B. Mcclure, Jessica Parrish, Nina D. Shiffrin, Richard C. Reynolds, Gang Chen, R J.R. Blair, Ellen Leibenluft, Nathan A. Fox, Monique Ernst, Daniel S. Pine, Eric E. Nelson

Psychology Faculty Publications

1. Context. Amygdala and ventrolateral prefrontal cortex dysfunction manifests in adolescents with anxiety disorders when they view negatively-valenced stimuli in threatening contexts. Such fear-circuitry dysfunction may also manifest when anticipated social evaluation leads socially anxious adolescents to misperceive peers as threatening. 2. Objective. To determine whether photographs of negatively-evaluated smiling peers, viewed during anticipated evaluation, engage the amygdala and ventrolateral prefrontal cortex differentially in adolescents with and without social anxiety. 3. Design. Case-control study. 4. Setting. Government clinical research institute. 5. Participants. Fourteen adolescents with anxiety disorders associated with marked social concerns and 14 diagnosis-free adolescents, matched on sex, age, …

Telzer, Salvatore Mannuzza, John L. Moulton Iii, Mary Guardino, Carrie L. Masten, Erin B. Mcclure, Stephen Fromm, Daniel S. Pine, Monique Ernst

Psychology Faculty Publications

Objective. Offspring of parents with major depressive disorder (MDD) face three-fold higher risk for MDD than offspring without a family history. Although MDD is a major cause of morbidity and mortality, neural correlates of risk for MDD remain poorly understood. This study compares amygdala and nucleus accumbens activation in children and adolescents at high and low risk for MDD under varying attentional and emotional conditions. Methods. Thirty-nine juveniles, 17 offspring of parents with MDD (high-risk group) and 22 offspring of parents without histories of MDD, anxiety or psychotic disorders (low-risk group) completed a functional magnetic resonance imaging study. During imaging, …

Psychology Faculty Publications

Objective: To examine attention bias towards threat faces in a large sample of anxiety disordered youths using a well-established visual probe task.

Method: Study participants included 101 children and adolescents (ages 7- 18 years) with generalized anxiety disorder, social phobia and/or separation anxiety disorder enrolled in a multi-site anxiety treatment study. Non-anxious youths (n = 51; ages 9 – 18 years) were recruited separately. Participants were administered a computerized visual probe task that presents pairs of faces portraying threat (angry), positive (happy) and neutral expressions. They pressed a response-key to indicate the spatial location of a probe that replaced one …

Amygdala And Ventrolateral Prefrontal Cortex Activation To Masked Angry Faces In Children And Adolescents With Generalized Anxiety Disorder, Christopher S. Monk, Eva H. Telzer, Karin Mogg, Brendan P. Bradley, Xiaoquin Mai, Hugo M.C. Louro, Gang Chen, Erin Tone, Daniel S. Pine, Monique Ernst

Psychology Faculty Publications

1. Context. Vigilance to threat is a key feature of generalized anxiety disorder (GAD). The amygdala and ventrolateral prefrontal cortex comprise a neural circuit that is responsible for detection of threats. Disturbed interactions between these structures may underlie pediatric anxiety. To date, no study has selectively examined responses to briefly-presented threats (e.g. less than 50 msec) in GAD or in pediatric anxiety.

2. Objective. To investigate amygdala and ventrolateral prefrontal cortex activation during processing of briefly-presented threats in pediatric GAD.

3. Design. Case-control study.

4. Setting. Government clinical research institute.

5. Participants. Youth volunteers, 17 with GAD and 12 diagnosis-free. …

The Varieties Of Pathways To Dysfluent Reading Comparing Subtypes Of Children With Dyslexia At Letter, Word, And Connected Text Levels Of Reading, Maryanne Wolf, Robin Morris, Maureen Lovett, Tami Katzir, Young-Suk Kim

Psychology Faculty Publications

The majority of work on the double-deficit hypothesis (DDH) of dyslexia has been done at the letter and word levels of reading. Key research questions addressed in this study are (a) do readers with different subtypes of dyslexia display differences in fluency at particular reading levels (e.g., letter, word, and connected text)? and (b) do children with dyslexia identified by either low-achievement or ability–achievement discrepancy criteria show similar differences when classified by the DDH? To address these questions, the authors assessed a sample of 158 children with severe reading impairments in second and third grades on an extensive battery and …
