Trauma Exposure And Transdiagnostic Distress: Examining Shared And Ptsd-Specific Associations, Michael L. Crowe, Sage E. Hawn, Erika J. Wolf, Terence M. Keane, Brian P. Marx Jan 2023

Trauma Exposure And Transdiagnostic Distress: Examining Shared And Ptsd-Specific Associations, Michael L. Crowe, Sage E. Hawn, Erika J. Wolf, Terence M. Keane, Brian P. Marx

Psychology Faculty Publications

Dimensional models of psychopathology suggest that the causes and consequences of psychopathology are attributable to a combination of syndrome specific and transdiagnostic features. There is considerable evidence that trauma exposure confers risk for a wide range of psychiatric conditions, yet no previous work has specifically examined the higher-order effects of trauma exposure within a structural model. We examined transdiagnostic and PTSD-specific associations with multiple forms of trauma exposure within a nation-wide sample (N = 1,649; 50% female) of military Veterans over-selected for posttraumatic stress disorder (PTSD). A higher-order Distress variable was estimated using PTSD, major depressive disorder (MDD), and generalized …


An Introduction To Local And Global Health Behaviors Using A Collaborative Online International Learning Exchange, Niamh M. Higgins, Lisa B. Smith Jan 2023

An Introduction To Local And Global Health Behaviors Using A Collaborative Online International Learning Exchange, Niamh M. Higgins, Lisa B. Smith

Psychology Faculty Publications

Collaborative Online International Learning (COIL), uses technology to facilitate the engagement of students from different countries in collaborative coursework and sharing of cultural perspectives. The existing literature concerning COIL exchanges points to the need to further explore student satisfaction and engagement with such exchange projects, and whether course learning outcomes are being achieved. This practice paper describes a COIL exchange between students of health psychology at Mary Immaculate College, Ireland, and Sacred Heart University, in the United States. During this 10-week project students were required to engage in synchronous and asynchronous activities. Following the completion of the COIL project, students …


"I Just Want To Be Me, Authentically": Identity Shifting Among Racially And Ethnically Diverse Young Adults, Aerika Brittian Loyd, Dulce Wilkinson Westberg, Lenisha Williams, Marisha Humphries, Alan Meca, Julie Carmen Rodil Jan 2023

"I Just Want To Be Me, Authentically": Identity Shifting Among Racially And Ethnically Diverse Young Adults, Aerika Brittian Loyd, Dulce Wilkinson Westberg, Lenisha Williams, Marisha Humphries, Alan Meca, Julie Carmen Rodil

Psychology Faculty Publications

Identity shifting represents a common but complex social, behavioral, and cognitive phenomenon. However, some forms of identity shifting originate in response to structural, institutional, and interpersonal marginalization enacted on lower status groups, such as people of color in the United States. The current study investigated ways young adults from diverse ethnic/racial groups discussed shifting to fit in with White Americans (a dominant group) in the United States and their own ethnic/racial group (a minoritized group) and elucidated self-reported motivations for shifting. Participants consisted of 764 young adults (ages = 18–23) recruited from two large public universities in the Southeast and …

Psychopathology is a risk factor for accelerated biological aging and early mortality. We examined associations between broad underlying dimensions of psychopathology (reflecting internalizing and externalizing psychiatric symptoms), PTSD, and age-adjusted GrimAge (“GrimAge residuals”), a DNA methylation biomarker of mortality risk relative to age. We also examined neurobiological correlates of GrimAge residuals, including neurocognitive functioning, blood-based biomarkers (of inflammation, neuropathology, metabolic disease), and cortical thickness. Data from two independent trauma-exposed military cohorts (n = 647 [62.9% male, Mage = 52], n = 434 [90% male, Mage = 32]) were evaluated using linear regression models to test associations between …

Science is often perceived to be a self-correcting enterprise. In principle, the assessment of scientific claims is supposed to proceed in a cumulative fashion, with the reigning theories of the day progressively approximating truth more accurately over time. In practice, however, cumulative self-correction tends to proceed less efficiently than one might naively suppose. Far from evaluating new evidence dispassionately and infallibly, individual scientists often cling stubbornly to prior findings. Here we explore the dynamics of scientific self-correction at an individual rather than collective level. In 13 written statements, researchers from diverse branches of psychology share why and how they have …

Examining The Ecological Validity Of The Power Of Food Scale, Lindsay M. Howard, Kristin E. Heron, Kathryn E. Smith, Ross D. Crosby, Scott G. Engel, Stephen A. Wonderlich, Tyler B. Mason

Psychology Faculty Publications

Purpose

Appetite for palatable foods may impact eating-related behaviors in everyday life. The present study evaluated the real-world predictive validity of the Power of Food Scale (PFS) using ecological momentary assessment (EMA).

Methods

30 women who reported binge eating completed the PFS and related measures. Subsequently, during a 14-day assessment period, participants completed five daily EMA surveys of appetite and binge eating via text message and web.

Results

Results of generalized estimating equations showed that higher PFS scores were associated with higher momentary levels of hunger, eagerness to eat, and urge to eat but were unrelated to fullness, preoccupation with …


Developmental Perceptual Impairments: Cases When Tone-Deafness And Prosopagnosia Co-Occur, Sébastien Paquette, Hui C. Li, Sherryse L. Corrow, Stephanie S. Buss, Jason J.S. Barton, Gottfried Schlaug Oct 2018

Developmental Perceptual Impairments: Cases When Tone-Deafness And Prosopagnosia Co-Occur, Sébastien Paquette, Hui C. Li, Sherryse L. Corrow, Stephanie S. Buss, Jason J.S. Barton, Gottfried Schlaug

Psychology Faculty Publications

Studies have shown subtle gray and white matter abnormalities in subjects with several developmental disorders including prosopagnosia, tone-deafness, and dyslexia. Correlational evidence suggests that tone-deafness and dyslexia tend to co-occur, suggesting a link between these two developmental disorders. However, it is not known whether tone-deafness can also be associated with other developmental disorders such as impaired face recognition or prosopagnosia. We addressed this question by assessing face perception abilities in a group of tone-deaf individuals and matched non-tone-deaf subjects. The Cambridge (CFMT) and the Warrington (WRMT) face memory tests were used to assess face processing in the combined group of …


Preconceptional Health Behavior Change In Women With Overweight And Obesity: Prototype For Smart Strong Healthy Women Intervention, Frank T. Materia, Joshua M. Smyth, Kristin E. Heron, Marianne Hillemeier, Mark E. Feinberg, Patricia Fonzi, Danielle Symons Jan 2018

Preconceptional Health Behavior Change In Women With Overweight And Obesity: Prototype For Smart Strong Healthy Women Intervention, Frank T. Materia, Joshua M. Smyth, Kristin E. Heron, Marianne Hillemeier, Mark E. Feinberg, Patricia Fonzi, Danielle Symons

Psychology Faculty Publications

Background: The prevalence of maternal perinatal obesity is rising, and in turn, increases health risks and morbidity for both mother and child. Past evidence suggests the preconceptional Strong Healthy Women (SHW) intervention can reduce multiple biobehavioral risk factors for adverse perinatal health. The SHW intervention, however, was time- and resource-intensive to deliver. Mobile health (mHealth) technologies provide an opportunity to expand intervention reach while reducing implementation cost and burden. Previous research suggests that preconceptional women are broadly supportive of using smartphones for behavior change, yet few studies have elicited their specific preferences for a targeted mHealth intervention. The objective of …


Psychometric Properties Of A Modified Moral Injury Questionnaire In A Military Population, Abby L. Braitman, Allison R. Battles, Michelle L. Kelley, Hannah C. Hamrick, Robert J. Cramer, Sarah Ehlke, Adrian J. Bravo Jan 2018

Psychometric Properties Of A Modified Moral Injury Questionnaire In A Military Population, Abby L. Braitman, Allison R. Battles, Michelle L. Kelley, Hannah C. Hamrick, Robert J. Cramer, Sarah Ehlke, Adrian J. Bravo

Psychology Faculty Publications

Moral injury (MI) results from perpetration of or exposure to distressing events, known as morally injurious events (MIEs), that challenge moral beliefs and values. Due to the type of involvement in recent military conflicts, many veterans report MIEs that may cause dissonance and, in turn, MI. Although 2 existing measures assess MIEs, neither currently assesses the defining characteristics of MI (i.e., guilt, shame, difficulty forgiving self and others, and withdrawal). The present study reports the initial psychometric test of a modified version (Robbins, Kelley, Hamrick, Bravo, & White, 2017) of the Moral Injury Questionnaire—Military version (MIQ-M; Currier, Holland, Drescher, & …


Independent And Interactive Associations Of Negative Affect, Restraint, And Impulsivity In Relation To Binge Eating Among Women, Tyler B. Mason, Kathryn E. Smith, Jason M. Lavender, Robin J. Lewis Jan 2018

Independent And Interactive Associations Of Negative Affect, Restraint, And Impulsivity In Relation To Binge Eating Among Women, Tyler B. Mason, Kathryn E. Smith, Jason M. Lavender, Robin J. Lewis

Psychology Faculty Publications

There is growing recognition that impulsivity may serve as an underlying risk factor for binge eating. In addition, the association of impulsivity with binge eating may be moderated by other affective and cognitive risk factors. This study examined independent and interactive associations of negative affect, dietary restraint, and facets of impulsivity with binge eating. A diverse sample of 566 undergraduate women completed online questionnaires of study variables. Results revealed a three-way interaction of negative affect, dietary restraint, and attentional impulsivity in relation to binge eating. Women who were high on each of these three variables reported the greatest levels of …

Psychology Faculty Publications

Lesbian women face unique sexual minority stressors (SMS) because of their stigmatized and marginalized status in society. Existing studies of SMS are primarily cross-sectional and use global measures of SMS. The goal of the present study was to develop a brief daily measure of SMS for use in daily diary or ecological momentary assessment studies. Existing retrospective measures of SMS were reviewed, resulting in an initial pool of 29 items. Thirty-eight lesbian women (Mage = 24.3 years, range: 19–30 years) completed a daily web-based survey including the SMS items for 12 days. Two response scales were tested; participants were randomized …


Gambling-Like Behavior In Pigeons: 'Jackpot' Signals Promote Maladaptive Risky Choice, Aaron P. Smith, Joshua S. Beckmann, Thomas R. Zentall Jul 2017

Gambling-Like Behavior In Pigeons: 'Jackpot' Signals Promote Maladaptive Risky Choice, Aaron P. Smith, Joshua S. Beckmann, Thomas R. Zentall

Psychology Faculty Publications

Individuals often face choices that have uncertain outcomes and have important consequences. As a model of this environment, laboratory experiments often offer a choice between an uncertain, large reward that varies in its probability of delivery against a certain but smaller reward as a measure of an individual’s risk aversion. An important factor generally lacking from these procedures are gambling related cues that may moderate risk preferences. The present experiment offered pigeons choices between unreliable and certain rewards but, for the Signaled group on winning choices, presented a ‘jackpot’ signal prior to reward delivery. The Unsignaled group received an ambiguous …


Protective Behavioral Strategies As A Context-Specific Mediator: A Multilevel Examination Of Within- And Between-Person Associations Of Daily Drinking, Abby L. Braitman, Ashley N. Linden-Carmichael, James M. Henson Jan 2017

Protective Behavioral Strategies As A Context-Specific Mediator: A Multilevel Examination Of Within- And Between-Person Associations Of Daily Drinking, Abby L. Braitman, Ashley N. Linden-Carmichael, James M. Henson

Psychology Faculty Publications

Research indicates that a drinker’s environmental and social context can be differentially associated with drinking outcomes. Further, although many researchers have identified that more frequent use of protective behavioral strategies (PBS) is associated with lower alcohol consumption and negative consequences, scant research has examined how one’s drinking context may promote or hinder PBS use. The present study examined how the context of drinking each day (i.e., where and with whom) is associated with level of consumption and reported alcohol-related problems among n = 284 college drinkers (69.0% female) directly, as well as indirectly through the use of PBS. Two different …


Nonsuicidal Self-Injury As A Risk Factor For Purging Onset: Negatively Reinforced Behaviours That Reduce Emotional Distress, Elizabeth N. Riley, Heather A. Davis, Jessica L. Combs, Carol E. Jordan, Gregory T. Smith Jan 2016

Nonsuicidal Self-Injury As A Risk Factor For Purging Onset: Negatively Reinforced Behaviours That Reduce Emotional Distress, Elizabeth N. Riley, Heather A. Davis, Jessica L. Combs, Carol E. Jordan, Gregory T. Smith

Psychology Faculty Publications

Both nonsuicidal self-injury (NSSI) and purging behaviour are thought to involve harm to the self. The acquired capability for self-harm model holds that engaging in one self-harming behaviour increases the capability to tolerate harm to the self, thus increasing risk for engaging on other such behaviours. In addition, both behaviours are thought to serve the similar function of relief from distress. We thus tested whether engagement in one of these behaviours predicts the subsequent onset of the other. In a longitudinal design, 1158 first-year college women were assessed for purging and NSSI at two time points. Engagement in NSSI at …

Early Adverse Experiences And Health: The Transition To College, Kelly B. Filipkowski, Kristin E. Heron, Joshua M. Smyth

Psychology Faculty Publications

Objective: This study cross-sectionally and prospectively examined the impact of adversity experienced prior to college on the health and well-being of students adjusting to their first college semester. Methods: Two-hundred sixteen (216) first-year students completed measures of adverse life experiences, perceived stress, physical symptoms, and health-related behaviors during the first 2 weeks of college entry and again at the end of the first semester. Results: Reported adversity prior to college predicted greater perceived stress and physical symptoms at college entry and an increase in physical symptoms over the semester; perceived stress mediated the prospective changes. Early adversity …


Fifty Psychological And Psychiatric Terms To Avoid: A List Of Inaccurate, Misleading, Misused, Ambiguous, And Logically Confused Words And Phrases, Scott O. Lilienfeld, Katheryn C. Sauvigné, Steven J. Lynn, Robin L. Cautin, Robert D. Latzman, Irwin D. Waldman Aug 2015

Psychology Faculty Publications

The goal of this article is to promote clear thinking and clear writing among students and teachers of psychological science by curbing terminological misinformation and confusion. To this end, we present a provisional list of 50 commonly used terms in psychology, psychiatry, and allied fields that should be avoided, or at most used sparingly and with explicit caveats. We provide corrective information for students, instructors, and researchers regarding these terms, which we organize for expository purposes into five categories: inaccurate or misleading terms, frequently misused terms, ambiguous terms, oxymorons, and pleonasms. For each term, we (a) explain why it is …


New Insights Into William James's Personal Crisis In The Early 1870s: Part Ii. John Bunyan And The Resolution & Consequences Of The Crisis, David E. Leary Jan 2015

New Insights Into William James's Personal Crisis In The Early 1870s: Part Ii. John Bunyan And The Resolution & Consequences Of The Crisis, David E. Leary

Psychology Faculty Publications

This article, the second in a two-part sequence, will cast new light on the strong possibility that John Bunyan’s The Pilgrim’s Progress played a previously unrecognized role in inspiring James’s means of defense against the frightening hallucination and panic fear that characterized his well-known personal crisis in the early 1870s. It will also present an argument about the influence of his defensive measures upon his subsequent views on the nature and importance of attention and will in human life. Along the way, it will identify James’s specific, newly discovered copy of Bunyan’s The Pilgrim’s Progress and the specific, newly discovered …


New Insights Into William James’S Personal Crisis In The Early 1870s: Part 1. Arthur Schopenhauer And The Origin & Nature Of The Crisis, David E. Leary Jan 2015

New Insights Into William James’S Personal Crisis In The Early 1870s: Part 1. Arthur Schopenhauer And The Origin & Nature Of The Crisis, David E. Leary

Psychology Faculty Publications

This article, the first in a two-part sequence, will cast new light on the well-known “crisis of William James” by presenting evidence regarding the previously unrecognized role of Arthur Schopenhauer’s thought in shaping and intensifying the way in which James experienced this crisis. It will also relate Schopenhauer’s influence to prior issues that had concerned James, and in an appendix it will provide an overview of other areas in which Schopenhauer seems to have influenced James, both during and after his personal crisis. The second article in this sequence will present evidence in support of the strong possibility that John …


Predictors Of Online And Offline Sexual Activities And Behaviors Among Adolescents, Anna Ševčíková, Alexander T. Vazsonyi, Janelle Širůček, Štěpán Konečný Aug 2013

Predictors Of Online And Offline Sexual Activities And Behaviors Among Adolescents, Anna Ševčíková, Alexander T. Vazsonyi, Janelle Širůček, Štěpán Konečný

Psychology Faculty Publications

Despite the fact that many adolescents spend much time on the Internet, it is unknown who engages in sexually related online activities (SROA) and how these affect adolescent sexual development. The present longitudinal study on 323 adolescents (51.1% girls) aimed to explore how peer attachment processes predicted both SROA and offline sexual behaviors at the age of 17, while also considering puberty and prior offline sexual experiences in order to elucidate potential similarities or differences. Findings based on hierarchical, binary logistic regression analyses revealed that SROA were predicted by alienation attachment to peers (OR=3.36, p<0.05), puberty (OR=1.03, p<0.05), and prior SROA (OR=0.56, p<0.001), while only previous offline sexual experiences at the age of 15 increased the likelihood of offline sexual behaviors at the age of 17 (OR=6.04, p<0.001). Study findings indicate that the Internet provides an additional context for acquiring sexual experiences during adolescence.


A Moralist In An Age Of Scientific Analysis And Skepticism: Habit In The Life And Work Of William James, David E. Leary Jan 2013

A Moralist In An Age Of Scientific Analysis And Skepticism: Habit In The Life And Work Of William James, David E. Leary

Psychology Faculty Publications

In this chapter I will review how James got from his earlier position, which so readily fit the scientific and skeptical tenor of his age, to his later position, and I will indicate how the views he began to articulate by the mid-1870s became central to the doctrines he presented in his magisterial Principles of Psychology (1890) and in his subsequent work in psychology and philosophy. Along the way I will make it clear that even before 1872, when he was attending lectures and doing physiological research in Harvard's Medical School, James was a deeply engaged advocate of philosophy, which …

Shouldering A Silent Burden: The Toll Of Dirty Tasks, Benjamin E. Baran, Steven G. Rogelberg, Erika Carello Lopina, Joseph A. Allen, Christiane Spitzmüller, Mindy Bergman

Psychology Faculty Publications

Dirty work involves tasks that are stigmatized owing to characteristics that the public finds disgusting, degrading, or objectionable. Conservation of resources theory suggests such experiences should induce strain and decreased work satisfaction; social identity theory suggests such work should lead to strong psychological investment in the work, among other outcomes. Integrating these two perspectives, this study hypothesizes and presents quantitative evidence from 499 animal-shelter workers, demonstrating how dirty-work engagement relates to higher levels of strain, job involvement, and reluctance to discuss work while negatively influencing work satisfaction. Additionally, this study takes a unique perspective on dirty work by focusing on …

An Extension Of Sic Predictions To The Wiener Coactive Model, Joseph W. Houpt, James T. Townsend Jun 2011

An Extension Of Sic Predictions To The Wiener Coactive Model, Joseph W. Houpt, James T. Townsend

Psychology Faculty Publications

The survivor interaction contrasts (SIC) is a powerful measure for distinguishing among candidate models of human information processing. One class of models to which SIC analysis can apply are the coactive, or channel summation, models of human information processing. In general, parametric forms of coactive models assume that responses are made based on the first passage time across a fixed threshold of a sum of stochastic processes. Previous work has shown that the SIC for a coactive model based on the sum of Poisson processes has a distinctive down--up--down form, with an early negative region that is smaller than the …

Nice Guys Finish Fast And Bad Guys Finish Last: Facilitatory Vs. Inhibitory Interaction In Parallel Systems, Ami Eidels, Joseph W. Houpt, Nicholas Altieri, Lei Pei, James T. Townsend

Psychology Faculty Publications

Systems Factorial Technology is a powerful framework for investigating the fundamental properties of human information processing such as architecture (i.e., serial or parallel processing) and capacity (how processing efficiency is affected by increased workload). The Survivor Interaction Contrast (SIC) and the Capacity Coefficient are effective measures in determining these underlying properties, based on response-time data. Each of the different architectures, under the assumption of independent processing, predicts a specific form of the SIC along with some range of capacity. In this study, we explored SIC predictions of discrete-state (Markov process) and continuous-state (Linear Dynamic) models that allow for certain types …


The Statistical Properties Of The Survivor Interaction Contrast, Joseph W. Houpt, James T. Townsend Oct 2010

The Statistical Properties Of The Survivor Interaction Contrast, Joseph W. Houpt, James T. Townsend

Psychology Faculty Publications

The Survivor Interaction Contrast (SIC) is a powerful tool for assessing the architecture and stopping rule of a model of mental processes. Despite its demonstrated utility, the methodology has lacked a method for statistical testing until now. In this paper we briefly describe the SIC then develop some basic statistical properties of the measure. These developments lead to a statistical test for rejecting certain classes of models based on the SIC. We verify these tests using simulated data, then demonstrate their use on data from a simple cognitive task.
