Greater Benefits Of Multisensory Integration During Complex Sensorimotor Transformations., Verena N Buchholz, Samanthi C Goonetilleke, W Pieter Medendorp, Brian D Corneil

Brain and Mind Institute Researchers' Publications

Multisensory integration enables rapid and accurate behavior. To orient in space, sensory information registered initially in different reference frames has to be integrated with the current postural information to produce an appropriate motor response. In some postures, multisensory integration requires convergence of sensory evidence across hemispheres, which would presumably lessen or hinder integration. Here, we examined orienting gaze shifts in humans to visual, tactile, or visuotactile stimuli when the hands were either in a default uncrossed posture or a crossed posture requiring convergence across hemispheres. Surprisingly, we observed the greatest benefits of multisensory integration in the crossed posture, as indexed …

The Role Of Engagement Across Conceptually Distinct Treatment Elements For Social Anxiety Disorder, Timothy M. Emge

Department of Psychology: Dissertations, Theses, and Student Research

There are currently several efficacious treatments for social anxiety disorder (e.g. exposure therapy and cognitive therapy). Each of these treatments is thought to reduce symptoms of social anxiety by disrupting maintenance mechanisms of the disorder, yet mechanism of change research has not supported this view. The current study compared components from each therapy modality in order to better understand why symptoms reduce similarly between conceptually distinct treatments. Participants with high social anxiety were randomly assigned to give a speech with cognitive restructuring and engagement-enhancing procedures, cognitive preparation and video feedback, or a speech alone. Self-ratings of speech performance, confidence in …

Dimensions Of Individuals' Judgements About Sexual Attraction, Romantic Attachment, And Sexual Orientation, Luis F. Morales Knight

Department of Psychology: Dissertations, Theses, and Student Research

Despite 150 years of scientific interest in sexual orientation, contemporary investigators grapple with a number of serious difficulties. A precise, unified definition of sexual orientation appropriate for scientific use continues to elude researchers, most likely because there is still no single coherent theory of sexual orientation. This lack impedes research into the measurement of sexual orientation. Existing measurements of sexual orientation rely on partial or incompletely empirical research. The present study identified promising avenues for development of credible definitions, theories, and measurements of sexual orientation: (a) mate-selection tasks; (b) the idea that bisexually-identified individuals place a lower priority on partner …

Posttraumatic Stress And Myocardial Infarction Risk Perceptions In Hospitalized Acute Coronary Syndrome Patients, Donald Edmondson, Jonathan A. Shaffer, Ellen-Ge Denton, Daichi Shimbo, Lynn Clemow

Publications and Research

Posttraumatic stress disorder (PTSD) is related to acute coronary syndrome (ACS; i.e., myocardial infarction or unstable angina) recurrence and poor post-ACS adherence to medical advice. Since risk perceptions are a primary motivator of adherence behaviors, we assessed the relationship of probable PTSD to ACS risk perceptions in hospitalized ACS patients (n = 420). Participants completed a brief PTSD screen 3-7 days post-ACS, and rated their 1-year ACS recurrence risk relative to other men or women their age. Most participants exhibited optimistic bias (mean recurrence risk estimate between "average" and "below average"). Further, participants who screened positive for current PTSD (n …

Ministry Of Memories: Keys To Pastoral Care Of Non-Cognitive Persons, Reginald Corfield

Doctoral Dissertations and Projects

This work is intended to examine and study the theological and moral reasons to provide pastoral care to persons who have limited or no cognition. Dementia, Alzheimer's, certain other medical conditions and the aging process cause a loss of brain function that affects memory, thinking, behavior and judgment. Most Clergy wrestle with the fact as to whether there is any purpose in ministering to such persons especially when there is no verbal or non-verbal response. This paper involves surveys, research, collection of historical and biblical data and medical science to evaluate the disease process and explore ways in which to …

Multiple Peer Group Self-Identification And Adolescent Tobacco Use, C. Anderson Johnson, Juliana L. Fuqua, Peggy E. Gallaher, Jennifer B. Unger, Dennis R. Trinidad, Steve Sussman, Enrique Ortega

CGU Faculty Publications and Research

Associations between peer group self-identification and smoking were examined among 2,698 ethnically diverse middle school students in Los Angeles who self-identified with groups such as Rockers, Skaters, and Gamers. The sample was 47.1% male, 54.7% Latino, 25.4% Asian, 10.8% White, 9.1% Other ethnicity, and 59.3% children of immigrant parents. Multiple group self identification was common: 84% identified with two or more groups and 65% identified with three or more groups. Logistic regression analyses indicated that as students endorsed more high risk groups, the greater their risk of tobacco use. A classification tree analysis identified risk groups based on interactions among …

Love Means Never Having To Say You're Sorry, But What About Malpractice? A Look At Verbal And Nonverbal Factors Affecting Perceptions Of Apologies In A Medical Malpractice Case, Sarah Thimsen

Department of Psychology: Dissertations, Theses, and Student Research

Apologies are part of daily life and occur in a variety of contexts. A large body of literature on the effects of apologies indicated that apologies have a positive effect – those receiving apologies have more positive views of the transgressor (e.g., Bornstein, Rung, & Miller, 2002; Goei, Roberty, Meyer, & Carlyle, 1997; Robbennolt, 2003; Sitkin & Beis, 1993; Takaku, 2000). An area of emerging research in the realm of apologies is in the area of medical malpractice. The research presented here sought to expand on the field of apologies, specifically by examining the effects of an apology in a …

Adolescent Decision Making And Risk Behavior: A Neurobiological Approach, Jennifer M. Wolff

Department of Psychology: Dissertations, Theses, and Student Research

In this study, the neurobiological theory of adolescent decision making and risk taking and the dual-process decision making theory were tested in a sample of college students. Participants responded to questions in a survey about decision making style, socio-emotional processes, cognitive control processes, and deviant peers. The goals of the research were to test the relation between decision making processes (intuitive and deliberative) and risk behaviors, to test the potential overlap between intuitive and deliberative decision making as described in the more traditional dual-process models and the socio-emotional and cognitive control systems of the neurobiological model, and to extend the …

Encoding Of Sensory Prediction Errors In The Human Cerebellum., John Schlerf, Richard B Ivry, Jörn Diedrichsen

Brain and Mind Institute Researchers' Publications

A central tenet of motor neuroscience is that the cerebellum learns from sensory prediction errors. Surprisingly, neuroimaging studies have not revealed definitive signatures of error processing in the cerebellum. Furthermore, neurophysiologic studies suggest an asymmetry, such that the cerebellum may encode errors arising from unexpected sensory events, but not errors reflecting the omission of expected stimuli. We conducted an imaging study to compare the cerebellar response to these two types of errors. Participants made fast out-and-back reaching movements, aiming either for an object that delivered a force pulse if intersected or for a gap between two objects, either of which …

Useful Field Of View Predicts Driving In The Presence Of Distracters, Joanne M. Wood, Alex Chaparro, Philippe Lacherez, Louise Hickson

Publications

Purpose. The Useful Field of View (UFOV®) test has been shown to be highly effective in predicting crash risk among older adults. An important question which we examined in this study is whether this association is due to the ability of the UFOV to predict difficulties in attention-demanding driving situations that involve either visual or auditory distracters.

Methods. Participants included 92 community-living adults (mean age 73.6 +- 5.4 years; range 65– 88 years) who completed all three subtests of the UFOV involving assessment of visual processing speed (subtest 1), divided attention (subtest 2), and selective attention (subtest 3); driving safety …

Motivation & Loss Aversion In The Health Savings Account Paradigm, Michael Holtje

Department of Psychology: Dissertations, Theses, and Student Research

This investigation examined the role of “loss aversion” and consumers’ motivational orientations in the context of healthcare purchasing under the individual account paradigm and the defined benefit (insurance) paradigm. Specifically, this dissertation investigated (1) whether Health Savings Accounts (HSAs) encourage more prudent health care spending compared to traditional health insurance plans and (2) the impact of individuals' motivational preferences (either towards “gains” or towards “losses”) between decision tasks under each type of health plan.

Three experiments varied the type of healthcare plan that consumers had and the manner in which they received information (either as a “gain” or “loss”). The …

Stereological Assessment Of The Thalamus In A Rat Model Of Periventricular Nodular Heterotopia, Jason Lennox

Honors Projects

Malformations of neocortical development such as microgyria (MG) and periventricular nodular heterotopia (PNH) have been observed in the brains of language learning impaired (LLI) humans. Rats with MG have shown rapid auditory processing (RAP) deficits similar to acoustic deficits observed in some human LLI populations. Threlkeld et al., (2009) previously reported RAP and other learning impairments in rats with PNH resulting from disruption to embryonic neuronal cell division by way of Methylazoxymethanol (MAM) treatment on embryonic day 15 (E15). The thalamus and its subnuclei may be vulnerable to neurodevelopmental disruptions. Studies of MG rats have shown changes in cell size …

A Health Needs Assessment Of Arab-Americans In The Washington, Dc Area, Reem N. Ghoneim, Amita N. Vyas

GW Research Days 2012 and Earlier

Although Arab-Americans often face various health challenges due to the stress associated with immigration, cultural conflict in the U.S., and limited knowledge of the complex U.S. health system, there is a paucity of research examining health risks and behaviors among this ethnic group. This cross-sectional study assessed the health needs among Arabs living in the Washington, DC metropolitan area. Participants were recruited to take the survey online, reporting on health care access and utilization, risk behaviors, and health status. It also measured for associations between reported depression, discrimination, acculturation, and health. Quantitative analysis showed correlations between age and current tobacco …

Racial Disparity In The Diagnosis Of Conduct Disorder, Cortney R. Vanhook

Undergraduate Research Awards

African American youth are exposed to considerably more risk factors than their Caucasian counterparts, yet they are being diagnosed at comparably lower rates for Conduct Disorder (CD) in epidemiological studies. Empirical data supports the claim that African Americans are at greater risk of developing CD. However, the internal dysfunction benchmark of the Diagnostic Statistic Manual (DSM) discourages clinicians from diagnosing youth who display environmentally caused CD. The racial disparity in the diagnosis of CD is problematic for two reasons. First, African American youth who display antisocial personality are more likely to be referred to the justice system than to therapeutic …

A Comparison Of Dsm-Iv And Dsm-5 Panel Members’ Financial Associations With Industry: A Pernicious Problem Persists, Lisa Cosgrove, Sheldon Krimsky

Counseling and School Psychology Faculty Publication Series

All medical subspecialties have been subject to increased scrutiny about the ways by which their financial associations with industry, such as pharmaceutical companies, may influence, or give the appearance of influencing, recommendations in review articles and clinical practice guidelines. Psychiatry has been at the epicenter of these concerns, in part because of high-profile cases involving ghostwriting and failure to report industry-related income, and studies highlighting conflicts of interest in promoting psychotropic drugs. The revised Diagnostic and Statistical Manual of Mental Disorders (DSM), scheduled for publication in May 2013 by the American Psychiatric Association (APA), has created a firestorm of controversy …

Perceived Health In Lung Cancer Patients: The Role Of Positive And Negative Affect, Jameson K. Hirsch, Andrea R. Floyd, Paul R. Duberstein

ETSU Faculty Works

Purpose: To examine the association of affective experience and health-related quality of life in lung cancer patients, we hypothesized that negative affect would be positively, and positive affect would be negatively, associated with perceived health.

Methods: A sample of 133 English-speaking lung cancer patients (33% female; mean age = 63.68 years old, SD = 9.37) completed a battery of self-report surveys.

Results: Results of our secondary analysis indicate that trait negative affect was significantly associated with poor physical and social functioning, greater role limitations due to emotional problems, greater bodily pain, and poor general health. Positive affect was significantly associated …

Latent Print Examination And Human Factors: Improving The Practice Through A Systems Approach: The Report Of The Expert Working Group On Human Factors In Latent Print Analysis, David H. Kaye, Thomas Busey, Melissa R. Gische, Gerry Laporte, Scott A. Shappell, Et Al.

Publications

Fingerprints have provided a valuable method of personal identification in forensic science and criminal investigations for more than 100 years. Fingerprints left at crime scenes generally are latent prints—unintentional reproductions of the arrangement of ridges on the skin made by the transfer of materials (such as amino acids, proteins, polypeptides, and salts) to a surface. Palms and the soles of feet also have friction ridge skin that can leave latent prints. The examination of a latent print consists of a series of steps involving a comparison of the latent print to a known (or exemplar) print. Courts have accepted latent …

Psychology Faculty Publications

Using qualitative research methods interviews were conducted with college students regarding the sources they used in generating perceptions of professional counselors. Respondents believed that word of mouth, media sources, and personal experiences were responsible for their understandings of professional counselors. The findings have applications for leaders in professional counseling organizations.

Children's Cancer And Transplant Hospital: A Micro Town Within A Bubble, Kimia Samimi

Masters Theses 1911 - February 2014

As the greatest considerations in health-care design have traditionally been functional —hygiene, efficiency, and flexibility for changing technology— hospitals have evolved to become dehumanizing spaces. In this thesis two specific groups of chronically ill children who have among the longest inpatient stays are studied: cancer and organ transplant patients. Being under immunosuppressive drugs, these children are physically vulnerable thus are kept completely isolated. These long stays and isolation can be very depressing for them.

This thesis undertakes the challenge of designing a fully isolated space that doesn’t feel like one or in other words “a micro-town within a bubble”. The …

The Effects Of Adolescent Binge Drinking On Corticotropin-Releasing Factor Cells In The Amygdala And Social Predictors Of Alcohol Intake In Male And Female Rats, Chrisanthi Karanikas

Masters Theses 1911 - February 2014

Alcohol is one of the most common drugs of choice among adolescents. Normally, the method of consumption is drinking large quantities of alcohol in short periods of time, otherwise known as “binge drinking.” Corticotropin releasing factor (CRF) stress peptide producing cells in central nucleus of the amygdala (CeA) has been implicated in behavioral responses to stress and addiction. The goals of this thesis were to determine the effects of voluntary binge drinking in adolescence and vapor-induced alcohol dependence in adulthood on CRF cells in the CeA. These studies were done using an operant model of voluntary binge drinking in rodents …

Latino Adolescent Adjustment: An Examination Of Cultural Values, Maria I. Iturbide

Department of Psychology: Dissertations, Theses, and Student Research

In the U.S., 22% of children under the age of 18 are Latino and 52% of Latino children have at least one parent who is foreign-born (Fry & Passel, 2009). Latinos are likely to experience acculturative strains associated with a range of negative outcomes such as academic underachievement. A mixed method sequential explanatory design was used to examine the protective effects of cultural factors that may ameliorate the negative effects of acculturative strains on psychological and academic adjustment.

The quantitative phase of the study examined whether biculturalism and ethnic identity would reduce the negative influence of acculturation strains on adjustment …

Explaining The Longitudinal Association Between Puberty And Depression: Sex Differences In The Mediating Effects Of Peer Stress, Colleen S. Conley, Karen D. Rudolph, Fred B. Bryant

Psychology: Faculty Publications and Other Works

This research investigated whether exposure to peer stress serves as one pathway through which pubertal development contributes to depression over time, differentially for girls and boys. Youth (N = 149; 9.6–14.8 years) and their caregivers provided information at two waves, 1 year apart, on puberty (Wave 1), peer stress (occurring between Waves 1 and 2), and depression (Waves 1 and 2). Structural equation modeling analyses examined sex differences in the extent to which peer stress mediated the impact of pubertal status and timing on subsequent depression (i.e., tests of moderated mediation). Significant sex-moderated mediation was found for both pubertal status …

Neural Responses To Peer Rejection In Anxious Adolescents: Contributions From The Amygdala-Hippocampal Complex, Jennifer Y.F. Lau, Amanda E. Guyer, Erin Tone, Jessica Jenness, Jessica M. Parrish, Daniel S. Pine, Eric E. Nelson

Psychology Faculty Publications

Peer rejection powerfully predicts adolescent anxiety. While cognitive differences influence anxious responses to social feedback, little is known about neural contributions. Twelve anxious and 12 age-, gender- and IQ-matched, psychiatrically-healthy adolescents received ‘not interested’ and ‘interested’ feedback from unknown peers during a Chatroom task administered in a neuroimaging scanner. No group differences emerged in subjective ratings to peer feedback, but all participants reported more negative emotion at being rejected (than accepted) by peers to whom they had assigned high desirability ratings. Further highlighting the salience of such feedback, all adolescents, independent of anxiety levels, manifested elevated responses in the amygdala-hippocampal …

Ethnic And Immigration Status Differences On Child Indicators Of Health For European Americans And Latinos, Christina Granillo, David V. Chavez, Donna M. Garcia, Kelly Campbell

Psychology Faculty Publications

This study examined the effects of ethnicity and immigration status on subjective and objective health (Body Mass Index; BMI) for Latino and European American children. Social identity and comparison theories were used to frame the investigation. Southern California parents were randomly selected to complete a telephone interview about their children’s health yielding a sample of 165 European American and 152 Latino participants. Compared to European Americans, Latinos evidenced poorer subjective and objective health. Latino children who had a caregiver who was a citizen had better subjective health than Latino children whose caregiver was not a citizen. BMI was correlated with …

Discriminating Famous From Fictional Names Based On Lifetime Experience: Evidence In Support Of A Signal-Detection Model Based On Finite Mixture Distributions., Ben Bowles, Iain M Harlow, Melissa M Meeking, Stefan Köhler

Brain and Mind Institute Researchers' Publications

It is widely accepted that signal-detection mechanisms contribute to item-recognition memory decisions that involve discriminations between targets and lures based on a controlled laboratory study episode. Here, the authors employed mathematical modeling of receiver operating characteristics (ROC) to determine whether and how a signal-detection mechanism contributes to discriminations between moderately famous and fictional names based on lifetime experience. Unique to fame judgments is a lack of control over participants' previous exposure to the stimuli deemed "targets" by the experimenter; specifically, if they pertain to moderately famous individuals, participants may have had no prior exposure to a substantial proportion of the …

Distinct Patterns Of Functional And Effective Connectivity Between Perirhinal Cortex And Other Cortical Regions In Recognition Memory And Perceptual Discrimination., Edward B O'Neil, Andrea B Protzner, Cornelia Mccormick, D Adam Mclean, Jordan Poppenk, Anthony D Cate, Stefan Köhler

Brain and Mind Institute Researchers' Publications

Traditionally, the medial temporal lobe (MTL) is thought to be dedicated to declarative memory. Recent evidence challenges this view, suggesting that perirhinal cortex (PrC), which interfaces the MTL with the ventral visual pathway, supports highly integrated object representations in recognition memory and perceptual discrimination. Even with comparable representational demands, perceptual and memory tasks differ in numerous task demands and the subjective experience they evoke. Here, we tested whether such differences are reflected in distinct patterns of connectivity between PrC and other cortical regions, including differential involvement of prefrontal control processes. We examined functional magnetic resonance imaging data for closely matched …

Community Member Perspectives From Transgender Women And Men Who Have Sex With Men On Pre-Exposure Prophylaxis As An Hiv Prevention Strategy: Implications For Implementation, Gabriel R. Galindo, Ja'nina Walker Ph.D., Patrick Hazelton, Tim Lane, Wayne T. Steward, Stephen F. Morin, Emily A. Arnold

Psychology

Background: An international randomized clinical trial (RCT) on pre-exposure prophylaxis (PrEP) as an human immunodeficiency virus (HIV)-prevention intervention found that taken on a daily basis, PrEP was safe and effective among men who have sex with men (MSM) and male-to-female transgender women. Within the context of the HIV epidemic in the United States (US), MSM and transgender women are the most appropriate groups to target for PrEP implementation at the population level; however, their perspectives on evidenced-based biomedical research and the results of this large trial remain virtually unknown. In this study, we examined the acceptability of individual daily use …

Purging Of Memories From Conscious Awareness Tracked In The Human Brain, Benjamin Levy, Michael C. Anderson

Psychology

Understanding the neural basis of conscious experience and its regulation are fundamental goals of science. While recent research has made substantial progress in identifying the neural correlates of conscious experiences, it remains unclear how individuals exert control over the contents of awareness. In particular, can a memory that has entered the aware state be purged from consciousness if it is not currently desired? Here we tracked the correlates of consciousness in humans using functional magnetic resonance imaging and demonstrated the involvement of a downregulation mechanism that purges contents from conscious awareness. When individuals tried to prevent the retrieval of a …

Ensembles Of Human Mtl Neurons "Jump Back In Time" In Response To A Repeated Stimulus, M. W. Howard, Indre Viskontas, K. H. Shankar, I. Fried

Psychology

Episodic memory, which depends critically on the integrity of the medial temporal lobe (MTL), has been described as ‘‘mental time travel’’ in which the rememberer ‘‘jumps back in time.’’ The neural mechanism underlying this ability remains elusive. Mathematical and computational models of performance in episodic memory tasks provide a specific hypothesis regarding the computation that supports such a jump back in time. The models suggest that a representation of temporal context, a representation that changes gradually over macroscopic periods of time, is the cue for episodic recall. According to these models, a jump back in time corresponds to a stimulus …
