Developmental Changes In The Feedback Related Negativity From 8 To 14 Years, Yael Arbel, Kayleigh N. Mccarty, Mark S. Goldman, Emanuel Donchin, Ty Brumback

Psychology Faculty Publications

The study examined age related changes in the magnitude of the Feedback Related Negativity (FRN) in 8–14 year old children performing a variation of a Go/No-Go task. Participants were presented with four stimuli and tasked with mapping each of them either to a response or to a “no response” by trial and error guided by feedback. Feedback was valid for two stimuli (Go and No-Go) and invalid (.5 positive; .5 negative feedback) for the other two stimuli. The amplitude of the FRN was evaluated as a function of age separately for Go and No-Go …

Lagged Effects Of Substance Use On Ptsd Severity In A Randomized Controlled Trial With Modified Prolonged Exposure And Relapse Prevention, Denise A. Hien, Kathryn Z. Smith, Max Owens, Teresa Lopez-Castro, Lesia M. Ruglass, Santiago Papini

Psychology Faculty Publications

Objective: To advance understanding of the effectiveness of evidence-based treatments for comorbid posttraumatic stress disorder (PTSD) and substance use disorder (SUD), research must provide a more nuanced picture of how substance use affects change in PTSD symptoms over the course of treatments and whether prolonged exposure techniques can be efficacious during active substance use. A data set that included patients with PTSD/subthreshold-PTSD and SUD treated with an exposure-based intervention provided an opportunity to conduct a secondary analysis to test how patients’ substance use impacted PTSD change over treatment. Method: We applied growth models to week-to-week PTSD symptom and substance use …

Source Of Health Information And Unmet Healthcare Needs In Asian Americans, Yuri Jang, Jungwon Yoon, Nan Sook Park

School of Information Faculty Publications

BACKGROUND: Responding to the disparities in accessing and obtaining health information and healthcare among immigrant populations, the present study focused on Asian Americans. Using a sample that reflects Asian Americans' cultural and linguistic diversities, the goal was to explore the typologies of health information source and their predictability to unmet healthcare needs (i.e., the experience of not being able to get needed medical care).

METHODS: Data were drawn from the 2015 Asian American Quality of Life Survey (N = 2,592), conducted using culturally and linguistically sensitive approaches. Latent class analysis on nine sources of health information across interpersonal networks (family …


When So Much Information Is Available For Free On The Internet, Does The World Still Need Libraries?, Claudia J. Dold, Rashid Jayousi Jul 2018

When So Much Information Is Available For Free On The Internet, Does The World Still Need Libraries?, Claudia J. Dold, Rashid Jayousi

Tampa Library Faculty and Staff Publications

Libraries have traditionally been repositories of information, whether the media was clay, papyrus, velum, paper, or electronic. The main work of librarians has always been to organize and to locate information. In this new era of expanding information technology and communication (ICT), of advances in the use of the internet, and of the expansion of social media, the world has created new roles for librarians. Libraries are shifting orientation from being repositories to institutions specializing in information access and information services. In the past librarians largely controlled the content, organization, and access to information in their libraries. With the advent …

Psychology Faculty Publications

Incidence of post-traumatic stress disorder (PTSD) ranges from 3 to 30% in individuals exposed to traumatic events, with the highest prevalence in groups exposed to combat, torture, or rape. To date, only a few FDA approved drugs are available to treat PTSD, which only offer symptomatic relief and variable efficacy. There is, therefore, an urgent need to explore new concepts regarding the biological responses causing PTSD. Animal models are an appropriate platform for conducting such studies. Herein, we examined the chronic behavioral and neurobiological effects of repeated unpredictable stress (RUS) in a mouse model. 12 weeks-old C57BL/6J male mice were …


Societal Individualism–Collectivism And Uncertainty Avoidance As Cultural Moderators Of Relationships Between Job Resources And Strain, Seulki Jang, Winny Shen, Tammy D. Allen, Haiyan Zhang May 2018

Societal Individualism–Collectivism And Uncertainty Avoidance As Cultural Moderators Of Relationships Between Job Resources And Strain, Seulki Jang, Winny Shen, Tammy D. Allen, Haiyan Zhang

Psychology Faculty Publications

The job demands–resources model is a dominant theoretical framework that describes the influence of job demands and job resources on employee strain. Recent research has highlighted that the effects of job demands on strain vary across cultures, but similar work has not explored whether this is true for job resources. Given that societal characteristics can influence individuals' cognitive structures and, to a lesser extent, values in a culture, we address this gap in the literature and argue that individuals' strain in reaction to job resources may differ across cultures. Specifically, we theorize that the societal cultural dimensions of individualism–collectivism and …


Examination Of Approach And Avoidance Inclinations On The Reinforcing Value Of Alcohol, Emily T. Noyes, Robert C. Schlauch Apr 2018

Examination Of Approach And Avoidance Inclinations On The Reinforcing Value Of Alcohol, Emily T. Noyes, Robert C. Schlauch

Psychology Faculty Publications

Although behavioral economics tends to focus on environmental factors (i.e., price, availability) that act to influence valuation of alcohol, recent research has begun to address how motivational and cognitive factors influence an individual's demand for alcohol. Motivational states, including craving, are one possible mechanism underlying the value based decision making that demand represents. Using a multidimensional model of craving (Ambivalence Model of Craving), the current study examined the relationships between indices of alcohol demand (i.e., reinforcing value of alcohol) and craving (i.e., approach inclinations), and the ways in which competing desires moderate that relationship (i.e., avoidance inclinations). Individuals who reported …


The Role Of Craving In Emotional And Uncontrolled Eating, Christina L. Verzijl, Erica Ahlich, Robert C. Schlauch, Diana Rancourt Apr 2018

The Role Of Craving In Emotional And Uncontrolled Eating, Christina L. Verzijl, Erica Ahlich, Robert C. Schlauch, Diana Rancourt

Psychology Faculty Publications

This study presents a novel application of the cognitive processing model of alcohol craving (CPMA) from the addictions field to the role of food craving in the well-established restrained eating–overeating relationship associated with binge eating disorder (BED). A community sample (N = 1058, ages 18-66) completed an online survey assessing four core domains: restrained eating, trait food craving, uncontrolled eating, and emotional eating. In accordance with the CPMA, food craving emerged as a significant indirect effect of the association between restrained eating and both uncontrolled and emotional eating. Gender did not significantly moderate any direct or indirect associations, suggesting that …


On The Measurement Of Thin‐Ideal Internalization: Implications For Interpretation Of Risk Factors And Treatment Outcome In Eating Disorders Research, Joel K. Thompson, Lauren M. Schaefer, Robert F. Dedrick Apr 2018

On The Measurement Of Thin‐Ideal Internalization: Implications For Interpretation Of Risk Factors And Treatment Outcome In Eating Disorders Research, Joel K. Thompson, Lauren M. Schaefer, Robert F. Dedrick

Psychology Faculty Publications

Objective: Although the Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ) and Ideal Body Stereotype Scale (IBSS) are used interchangeably to assess thin ideal internalization, limited work has examined the assumption that the two measures index the same construct.

Method: The current study utilized confirmatory factor analysis to examine whether these measures capture a single construct (one‐factor), two constructs (two‐factor), or both shared and unique constructs (bifactor). The SATAQ‐4R‐Internalization: Thin/Low Body Fat subscale and IBSS‐Revised were administered to 1,114 college females.

Results: A bifactor model provided the best fit to the data. Further, the SATAQ‐4R was more strongly related to disordered eating …

Thinness Pressures In Ethnically Diverse College Women In The United States, Daniel L. Ordaz, Lauren M. Schaefer, Emily M. Choquette, Jordan Schueler, Lisa Wallace, Joel K. Thompson Mar 2018

Thinness Pressures In Ethnically Diverse College Women In The United States, Daniel L. Ordaz, Lauren M. Schaefer, Emily M. Choquette, Jordan Schueler, Lisa Wallace, Joel K. Thompson

Psychology Faculty Publications

While research consistently supports the negative impact of thinness pressures on body image, this work has primarily utilized White samples in the United States, limiting generalizability to other ethnicities. Further, limited research has examined ethnic differences in thinness pressures from distinct sociocultural influences. This study examined distinct sources of thinness pressures in 598 White, 135 Black, and 131 Hispanic college women in the United States. Mean levels of thinness pressures significantly differed across ethnicity, with Black women generally reporting the lowest levels of each pressure. Additionally, distinct sources of thinness pressures were more highly related to negative outcomes within ethnic …


Self-Objectification, Body Shame, And Disordered Eating: Testing A Core Mediational Model Of Objectification Theory Among White, Black, And Hispanic Women, Lauren M. Schaefer, Natasha L. Burke, Rachel M. Calogero, Jessie E. Menzel, Ross Krawczyk, Joel Kevin Thompson Mar 2018

Self-Objectification, Body Shame, And Disordered Eating: Testing A Core Mediational Model Of Objectification Theory Among White, Black, And Hispanic Women, Lauren M. Schaefer, Natasha L. Burke, Rachel M. Calogero, Jessie E. Menzel, Ross Krawczyk, Joel Kevin Thompson

Psychology Faculty Publications

Objectification theory asserts that self-objectification, which manifests as self-surveillance, leads to increased body shame and subsequent eating pathology. Although evidence supports the core mediational model, the majority of this work utilizes primarily White samples, limiting generalizability to other ethnic groups. The current study examined whether the core tenets of objectification theory generalize to Black and Hispanic women. Participants were 880 college women from the United States (71.7% White, 15.1% Hispanic, 13.2% Black) who completed self-report measures of self-surveillance, body shame, and disordered eating. Multivariate analysis of variance tests indicated lower levels of self-surveillance and disordered eating among Black women. Moreover, …

Credibility and trustworthiness are the bedrock upon which any science is built. The strength of these foundations has been increasingly questioned across the sciences as instances of research misconduct and mounting concerns over the prevalence of detrimental research practices have been identified. Consequently, the purpose of this article is to encourage our scientific community to positively and proactively engage in efforts that foster a healthy and robust industrial and organizational (I-O) psychology. We begin by advancing six defining principles that we believe reflect the values of robust science and offer criteria for evaluating proposed efforts to change scientific practices. Recognizing …

Genetic And Environmental Influences On The Codevelopment Among Borderline Personality Disorder Traits, Major Depression Symptoms, And Substance Use Disorder Symptoms From Adolescence To Young Adulthood, Marina A. Bornovalova, Brad Verhulst, Troy Alan Webber, Matt Mcgue, William G. Iacono, Brian M. Hicks

Psychology Faculty Publications

Although borderline personality disorder (BPD) traits decline from adolescence to adulthood, comorbid psychopathology such as symptoms of major depressive disorder (MDD), alcohol use disorder (AUD), and drug use disorders (DUDs) likely disrupt this normative decline. Using a longitudinal sample of female twins (N = 1,763), we examined if levels of BPD traits were correlated with changes in MDD, AUD, and DUD symptoms from ages 14 to 24. A parallel process biometric latent growth model examined the contributions of genetic and environmental factors to the relationships between developmental components of these phenotypes. Higher BPD trait levels predicted a greater rate of …

Preliminary Evidence That Digit Length Ratio (2d:4d) Predicts Neural Response To Delivery Of Motivational Stimuli, Troy A. Webber, Heather E. Soder, Geoffrey Potts, Marina A Bornovalova

Psychology Faculty Publications

Reduced relative length of the 2nd to 4th digits (2D:4D) is thought to partially reflect fetal testosterone (FT) exposure, a process suspected to promote relatively permanent effects on the brain and behavior via structural and functional neuroadaptations. We examined the effect of 2D:4D on neural response − assessed by P2a and feedback-related negativity (FRN) event-related potentials (ERPs) − to motivational stimuli (reward or punishment) using two counterbalanced conditions of a passive S1/S2 outcome prediction design. P2a to expected and unexpected delivered rewards or punishments ($1 or white noise burst, respectively) and FRN to withheld rewards or punishments ($0 or silence, …

Use Of 'Eradication' In Hiv Cure-Related Research: A Public Health Debate, Karine Dubé, Stuart Luter, Breanne Lesnar, Luke Newton, Jerome T. Galea, Brandon Brown, Sarah Gianella

Social Work Faculty Publications

Background: The landscape of Human Immunodeficiency Virus (HIV) research has changed drastically over the past three decades. With the remarkable success of antiretroviral treatment (ART) in decreasing AIDS-related mortality, some researchers have shifted their HIV research focus from treatment to cure research. The HIV cure research community often uses the term eradication to describe the science, and talks about eradicating the virus from the body. In public discourse, the term eradication could be conflated with disease eradication at the population level. In this paper, we call for a reframing of HIV cure research as control, as it is a …

How Do Electronic Cigarettes Affect Cravings To Smoke Or Vape? Parsing The Influences Of Nicotine And Expectancies Using The Balanced-Placebo Design, Amanda Palmer, Thomas H. Brandon

Psychology Faculty Publications

Objective: Although electronic cigarettes (e-cigarettes) are frequently initiated for smoking cessation, results from the first two clinical trials testing this suggest that the perceived benefits of vaping may be influenced by non-nicotine factors, including cognitive outcome expectancies. The current study investigated the separate and combined effects of nicotine delivery and outcome expectancies on cravings for cigarettes and e-cigarettes using a balanced-placebo experiment. Method: Drug dosage (contains nicotine or not) was crossed with instructional set (told nicotine or non-nicotine) during ad lib e-cigarette use sessions by 128 current e-cigarette users (52 identifying as current cigarette smokers or “dual users”). It was …
