On Reporting The Onset Of The Intention To Move, Uri Maoz, Liad Mudrik, Ram Rivlin, Ian Ross, Adam Mamelak, Gideon Yaffe

Psychology Faculty Books and Book Chapters

"In 1965, Hans Kornhuber and Luder Deecke made a discovery that greatly influenced the study of voluntary action. Using electroencephalography (EEG), they showed that when aligning some tens of trials to movement onset and averaging, a slowly decreasing electrical potential emerges over central regions of the brain. It starts 1 second ( s) or so before the onset of the voluntary action1 and continues until shortly after the action begins. They termed this the Bereitschaftspotential, or readiness potential (RP; Kornhuber & Deecke, 1965).2 This became the first well-established neural marker of voluntary action. In that, the RP allowed for more …

Predicting Changes In Negative Emotional Eating Following Bariatric Weight-Loss Surgery, Nomalungelo M. Nolutshungu, Kimberly Mcclure Brenchley, Alexis Conason, Allan Geliebter

Psychology Faculty/Staff Publications

Background: Obesity has been associated with higher rates of social anxiety, and social anxiety has been linked to increased emotional eating. We hypothesized that reductions in BMI and social anxiety following bariatric surgery would predict decreases in negative emotional eating.

Methods: Participants were 206 bariatric weight loss surgery patients who completed self-report questionnaires. Liebowitz Social Anxiety Scale (LSAS) scores measured social anxiety. Scores from the negative emotion subscale in the Emotional Appetite Questionnaire (EMAQ) reflected eating due to negative emotions. BMI was calculated from self-report data. All data were collected shortly preceding surgery and at 1-year post surgery.

Results: Multiple …

Developing An Animal Model Of Polysubstance Abuse In Adolescence: The Role Of Nmda Receptors In Alcohol/Cocaine Reward, Adriana Rebecca Uruena-Agnes

USF Tampa Graduate Theses and Dissertations

Repeated exposure to drugs of abuse conditions individuals to anticipate the behavioral consequences of drug use specifically in the presence of a drug-associated context. In rodents, preferences and aversions for alcohol and cocaine have been conditioned; however, the mechanisms underlying the expression of these conditioned effects remain unknown. Given that alcohol and cocaine polysubstance abuse is prevalent in young individuals, with more than 50% of these polysubstance abusers reporting to be under the age of 21, it is important to understand the mechanisms contributing to the behavioral effects of alcohol and cocaine co-dependency. Aim 1 determined if age differentially impacted …

Using An Acceptance And Commitment Training Protocol To Decrease Drug Use, Alexander Brown Mclean

USF Tampa Graduate Theses and Dissertations

Behavior analysts have had much success in affecting behavior change with individuals diagnosed with intellectual disabilities as well as those who would be considered typically developing with a variety of intervention strategies; most of which involve affecting direct acting contingencies. However, the realm of language-based psychopathology has just begun to be addressed within the field through language based, or indirect acting strategies. Acceptance and Commitment Therapy (ACT) is based on the concept of derived stimulus relations and allows for a behavior analytic treatment of language-based psychopathology. The current study was intended to test the efficacy of a brief protocol-delivered ACT …

Gender Differences In Exercise Dependence And Eating Disorders In Young Adults: A Path Analysis Of A Conceptual Model, Tevni Grajales, Shelli Meulemans, Peter Pribis, Gretchen Krivak

Faculty Publications

Abstract: The purpose of our study was to study the prevalence of exercise dependence (EXD) among college students and to investigate the role of EXD and gender on exercise behavior and eating disorders. Excessive exercise can become an addiction known as exercise dependence. In our population of 517 college students, 3.3% were at risk for EXD and 8% were at risk for an eating disorder. We used Path analysis the simplest case of Structural Equation Modeling (SEM) to investigate the role of EXD and exercise behavior on eating disorders. We observed a small direct effect from gender to eating disorders. …

Relating Relations: The Impact Of Equivalence-Equivalence Training On Analogical Reasoning, Anna Rosio Garcia

USF Tampa Graduate Theses and Dissertations

A well-researched line showing equivalence performances in a wide variety of areas has been conducted in the field of Behavior Analysis (BA). One area demonstrates that relating relations is a behavioral account of analogical thinking. Relating relations may have implications for the development of analogical training given that analogical reasoning is seen as the foundation of intelligence yet research in this area is limited. A protocol by Stewart, Barnes-Holmes, and Weil (2009) was developed to train children in analogical reasoning using equivalence-equivalence relations. The purpose of this study was to evaluate an equivalence-equivalence training protocol based on Stewart et al. …

Crimes Against Children Research Center

This exploratory study was conducted to better assess how technology can be used in criminal investigations; it is important to get a better understanding of how technology is currently employed in child sex trafficking as well as the approaches and needs of law enforcement. 144 investigators from Internet Crimes Against Children (ICAC) Task Forces and affiliate agencies responded to an online semi‐structured survey, including 45 investigators with experience conducting investigations of the commercial sexual exploitation of children (CSEC) that involved technology. Participants included investigators working in local, county, and state law enforcement agencies in the United States. The discussion suggested …

Universities Need To Do More To Prevent Heterosexism To Support Lgb Students’ Academic Success, M.R. Woodford

Clear Language Summaries

Heterosexism can affect lesbian, gay and bisexual (LGB) students’ academic success. Peer-group support and general faculty support do not protect students from the impacts of heterosexism, but is still important. To prevent poor academic outcomes, campuses must have spaces in which students feel safe to come out and heterosexism needs to be eliminated on campus.

Psychosocial Factors In Sports Injury Rehabilitation And Return To Play, Leslie W. Podlog, John Heil, Stefanie Podlog (Nee Schulte)

Athletic Training Collection

This article discusses the principles and practices that guide psychological intervention with injury, and encourages a psychological approach to injury for clinicians. Part 1 reviews the research literature, and serves as a foundation for the review of clinical practices in part 2. Examination of the research literature highlights 4 areas: (1) psychological factors influencing rehabilitation, (2) social factors affecting rehabilitation, (3) performance concerns among returning athletes, and (4) tools/inventories for assessing psychological readiness to return. A synopsis of an injury intervention plan is provided, and the influence of pain and fear in the rehabilitation process is described.

Defining And Assessing Animal Pain, Lynne U. Sneddon, Robert W. Elwood, Shelley A. Adamo, Matthew C. Leach

Experimentation Collection

The detection and assessment of pain in animals is crucial to improving their welfare in a variety of contexts in which humans are ethically or legally bound to do so. Thus clear standards to judge whether pain is likely to occur in any animal species is vital to inform whether to alleviate pain or to drive the refinement of procedures to reduce invasiveness, thereby minimizing pain. We define two key concepts that can be used to evaluate the potential for pain in both invertebrate and vertebrate taxa. First, responses to noxious, potentially painful events should affect neurobiology, physiology and behaviour …

Developmental Differences In The Influence Of Phonological Similarity On Spoken Word Processing In Mandarin Chinese., Jeffrey G Malins, Danqi Gao, Ran Tao, James R Booth, Hua Shu, Marc F Joanisse, Li Liu, Amy S Desroches

Brain and Mind Institute Researchers' Publications

The developmental trajectory of spoken word recognition has been well established in Indo-European languages, but to date remains poorly characterized in Mandarin Chinese. In this study, typically developing children (N=17; mean age 10; 5) and adults (N=17; mean age 24) performed a picture-word matching task in Mandarin while we recorded ERPs. Mismatches diverged from expectations in different components of the Mandarin syllable; namely, word-initial phonemes, word-final phonemes, and tone. By comparing responses to different mismatch types, we uncovered evidence suggesting that both children and adults process words incrementally. However, we also observed key developmental differences in how subjects treated onset …

Striatum In Stimulus-Response Learning Via Feedback And In Decision Making., Nole M Hiebert, Andrew Vo, Adam Hampshire, Adrian M Owen, Ken N Seergobin, Penny A Macdonald

Brain and Mind Institute Researchers' Publications

Cognitive deficits are recognized in Parkinson's disease. Understanding cognitive functions mediated by the striatum can clarify some of these impairments and inform treatment strategies. The dorsal striatum, a region impaired in Parkinson's disease, has been implicated in stimulus-response learning. However, most investigations combine acquisition of associations between stimuli, responses, or outcomes (i.e., learning) and expression of learning through response selection and decision enactment, confounding these separate processes. Using neuroimaging, we provide evidence that dorsal striatum does not mediate stimulus-response learning from feedback but rather underlies decision making once associations between stimuli and responses are learned. In the experiment, 11 males …

East Asian Low Marriage And Birth Rates: The Role Of Social Status Affordance In Marriage And Childbearing Behavior, Jose C. Yong

Dissertations and Theses Collection (Open Access)

Although declines in marriage and birth rates are generally associated with industrialization and economic advancement, countries with a dominantly East Asian cultural population exhibit the lowest marriage and birth rates in the developed world. This study aims to identify and verify a new latent construct, social status affordance, as an underlying account for the differences in long-term mating outcomes (i.e., marriage and childbearing) between developed East Asian countries and other developed countries. Drawing on an understanding of the specific East Asian cultural values of harmony and deference and, subsequently, the importance of social status conferred by educational and occupational prestige …

How Fun Are Your Meetings? Investigating The Relationship Between Humor Patterns In Team Interactions And Team Performance, Nale Lehmann-Willenbrock, Joseph A. Allen

Psychology Faculty Publications

Research on humor in organizations has rarely considered the social context in which humor occurs. One such social setting that most of us experience on a daily basis concerns the team context. Building on recent theorizing about the humor—performance association in teams, this study seeks to increase our understanding of the function and effects of humor in team interaction settings. Specifically, we examine behavioral patterns of humor and laughter in real teams. We videotaped and coded humor and laughter during 54 regular organizational team meetings. Performance ratings were obtained immediately following the team meetings as well as at a later …

Adolescent, But Not Adult, Binge Ethanol Exposure Leads To Persistent Global Reductions Of Choline Acetyltransferase Expressing Neurons In Brain, Ryan P. Vetreno, Margaret Broadwater, Wen Liu, Linda Spear, Fulton T. Crews

Psychology Faculty Scholarship

During the adolescent transition from childhood to adulthood, notable maturational changes occur in brain neurotransmitter systems. The cholinergic system is composed of several distinct nuclei that exert neuromodulatory control over cognition, arousal, and reward. Binge drinking and alcohol abuse are common during this stage, which might alter the developmental trajectory of this system leading to long-term changes in adult neurobiology. In Experiment 1, adolescent intermittent ethanol (AIE; 5.0 g/kg, i.g., 2-day on/2-day off from postnatal day [P] 25 to P55) treatment led to persistent, global reductions of choline acetyltransferase (ChAT) expression. Administration of the Toll-like receptor 4 agonist lipopolysaccharide to …

Social Media And Young Adult's Well-Being, Clayton Howard

Master's Theses or Doctor of Nursing Practice

Social media has become an integral part of young adult’s lives today. It has moved well beyond simple entertainment, and now can have a profound effect on many areas of functioning. The current study examines various aspects of well-being to see if there is a connection between social media use and global well-being. The participants for this study were 217 undergraduate students from Fort Hays State University. Participants completed a survey designed to measure overall well-being and broad aspects of overall well-being that included the Public Health Surveillance Well-Being Scale (PHS-WB), the Rosenberg Self-Esteem Scale (RSES), the Relationship Assessment Scale …

Modeling Hedonic Processing And Anhedonia In Depression, Kevin Mercado

Honors College Theses

Depression is characterized by low positive emotion and a lack of pleasurable experiences, or anhedonia. Past studies have emphasized controlling negative affect, but there is an emerging trend in the depression literature to focus on positive emotion. The current study employed several psychophysiological tools, postauricular reflex, startle blink reflex, and event-related potential (ERP) components such as P3 and the late positive potential (LPP), to assess the dissociable components in positive emotion (consummatory and anticipatory processes). In addition, several different hypotheses of emotional dysfunction were evaluated to accurately model deficits in positive emotionality. A majority of the psychophysiological tools used supported …

Identifying Elementary School Student Understanding Of Learning Disabilities, Michael Quinn Bair

Theses and Dissertations

This school-based study examined the knowledge level of third through fifth grade students who are not being served in special education regarding learning disabilities, personal learning styles, and their perceptions of their peers with learning disabilities. This study circumvents teachers', administrators', and parents' awareness which has been thoroughly researched and instead, directly assesses through interviews what elementary students (n=45) know about learning disabilities. The goal of this study was to gain a greater understanding of what the students' perceptions are of their learning experience in general and what their understanding of learning disabilities are more specifically through interviews to give …

Multi-Region Hemispheric Specialization Differentiates Human From Nonhuman Primate Brain Function, H-Y. Wey, Kimberley A. Phillips, D. R. Mckay, A. R. Laird, P. Kochunov, M. D. Davis, D. C. Glahn, T. Q. Duong, P. T. Fox

Psychology Faculty Research

The human behavioral repertoire greatly exceeds that of nonhuman primates. Anatomical specializations of the human brain include an enlarged neocortex and prefrontal cortex (Semendeferi et al. in Am J Phys Anthropol 114:224–241, 2001), but regional enlargements alone cannot account for these vast functional differences. Hemispheric specialization has long believed to be a major contributing factor to such distinctive human characteristics as motor dominance, attentional control and language. Yet structural cerebral asymmetries, documented in both humans and some nonhuman primate species, are relatively minor compared to behavioral lateralization. Identifying the mechanisms that underlie these functional differences remains a goal of considerable …

Looking On The Dark Side: Rumination And Cognitive Bias Modification, Paula T. Hertel, Nilly Mor, Chiara Ferrari, Olivia Hunt, Nupur Agrawal

Psychology Faculty Research

To understand cognitive bases of self-reported ruminative tendencies, we examined interpretations and subsequent memories of ambiguous situations depicting opportunities for rumination. In Experiment 1, we recruited students, randomly assigned them to a distracting or ruminative concentration task, and then measured their latencies to complete fragments that resolved situational ambiguity in either a ruminative or a benign direction. Students in the ruminative task condition who previously self-identified as brooders were quicker to complete ruminative fragments. In Experiment 2, we simulated this bias to investigate its possible contribution to rumination; nonbrooding students were trained to make ruminative or benign resolutions of ambiguous …

Moderators And Predictors Of Response To Eating Disorder Risk Factor Reduction Programs In Collegiate Female Athletes, T M. Stewart, Maribel Plasencia, H Han, H Jackson, Carolyn Becker

Psychology Faculty Research

Objective

The primary aim of this paper was to investigate moderators and predictors of response to two programs designed to reduce eating disorder risk factors in collegiate female athletes. This study served as an ancillary study to a parent trial that investigated the feasibility of an athlete modified cognitive dissonance-based program (AM-DBP) and an athlete modified healthy weight intervention program (AM-HWI).

Design

157 female collegiate athletes were randomized to either the AM-DBP or the AM-HWI program. Participants completed surveys at baseline, post-intervention, 6 weeks, and 1 year.

Methods

After classifying sports as either lean or non-lean, we investigated if sport …

Adolescent Bisphenol-A Exposure Decreases Dendritic Spine Density: Role Of Sex And Age, Rachel E. Bowman, Victoria N. Luine, Hameda Khandaker, Joseph J. Villafane, Maya Frankfurt

Psychology Faculty Publications

Bisphenol-A (BPA), a common environmental endocrine disruptor, modulates estrogenic, androgenic, and anti-androgenic effects throughout the lifespan. We recently showed that low dose BPA exposure during adolescence increases anxiety and impairs spatial memory independent of sex. In the current study, six week old Sprague Dawley rats (n=24 males, n=24 females) received daily subcutaneous injections (40 µg/kg bodyweight) of BPA or vehicle for one week. Serum corticosterone levels in response to a 1 h restraint stress and spine density were examined at age 7 (cohort 1) and 11 (cohort 2) weeks. Adolescent BPA exposure did not alter stress dependent corticosterone responses but …

Cultural Differences In Prioritizing Applicant Attributes When Assessing Employment Suitability, Serena Wee, Peter K. Jonason, Norman P. Li

Research Collection School of Social Sciences

We examined how culture influences perceptions of applicant attributes when assessing employment suitability. In two studies (N = 408), we compared members from a collectivistic society (Singapore) to two samples from individualistic societies (the United States and Australia) on their perceptions of applicant attributes across job contexts. For each job, participants either chose between candidates with different attribute profiles or created ideal candidates by allocating a fixed amount of percentile points across different attributes. More often than Australians, Singaporeans chose the candidate with higher levels of the trait (e.g., openness to experience) uniquely associated with the job (e.g., graphic designer). …

Cultural Psychological Theory, Kimin Eom, Heejung S. Kim

Research Collection School of Social Sciences

Cultural psychology has revived the original intention of the cognitive revolution in which psychologists aimed to bring meaning to the study of the mind (Bruner, 1990). In contrast to much of psychological research that has been devoted to discovering “pure” context-free psychological mechanisms, the basic assumption of cultural psychology is that the human psyche cannot exist independently of its sociocultural contexts, and therefore, the study of human actions must consider the contexts in which these actions take place (Shweder, 1995). From the beginning, cultural psychology has aimed to understand the mutual influence between psyche and cultural contexts. According to the …

Blue Is In The Eye Of The Beholder: A Cross Cultural Study On Color Perception And Memory, Mark Douglas Lowry

USF Tampa Graduate Theses and Dissertations

According the linguistic relativity hypothesis, the language one speaks affects how one thinks. Because languages differ in how they categorize color, linguistic relativity has often been tested by conducting experiments on color perception and memory. This study examines the linguistic relativity hypothesis using ecologically valid stimuli: pictures of eyes. Because Russian-speakers are more likely to describe blue/grey eyes as grey, whereas English speakers are more likely to describe them as blue, English and Russian participants were asked to match the overall color of blue eyes to a color scale. There were three conditions. In the first condition (perception), participants saw …

Dimensional Structure Of Dsm-5 Posttraumatic Stress Symptoms: Support For A Hybrid Anhedonia And Externalizing Behaviors Model, Cherie Armour, Jack Tsai, Tory A. Durham, Ruby Charak, Tracey L. Biehn, Jon D. Elhai, Robert H. Pietrzak

Department of Psychology: Faculty Publications

Several revisions to the symptom clusters of posttraumatic stress disorder (PTSD) have been made in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Central to the focus of this study was the revision of PTSD's tripartite structure in DSM-IV into four symptom clusters in DSM-5. Emerging confirmatory factor analytic (CFA) studies have suggested that DSM-5 PTSD symptoms may be best represented by one of two 6-factor models: (1) an Externalizing Behaviors model characterized by a factor which combines the irritability/anger and self-destructive/reckless behavior items; and (2) an Anhedonia model characterized by items of loss of …

Assessing The Effects Of Derived Relational Responding On Intraverbal Use Of Same-Opposite And More Than-Less Than Relations In Children With Autism, Jane P. White

USF Tampa Graduate Theses and Dissertations

Relational Frame Theory provides an analysis of verbal behavior involving a focus on the development of relational operants which are seen as a basis for language. From this basis, a framework is provided for establishing relational networks in individuals who lack derived relational ability. Establishment of relational frames may increase the probability of responding relationally to novel instances and use of the specific relational frames during social interactions; therefore, training verbal relations in accordance with an RFT approach may enhance intraverbal responding and facilitate the emergence of untrained responses. The purpose of this study was to evaluate the emergence of …

Specific Trauma Subtypes Improve The Predictive Validity Of The Harvard Trauma Questionnaire In Iraqi Refugees, Bengt B. Arnetz, Carissa L. Broadbridge, Hikmet Jamil, Mark A. Lumley, Nnamdi Pole, Evone Barkho, Monty Fakhouri, Yousif Rofa Talia, Judith E. Arnetz

Psychology: Faculty Publications

Trauma exposure contributes to poor mental health among refugees, and exposure often is measured using a cumulative index of items from the Harvard Trauma Questionnaire (HTQ). Few studies, however, have asked whether trauma subtypes derived from the HTQ could be superior to this cumulative index in predicting mental health outcomes. A community sample of recently arrived Iraqi refugees (N = 298) completed the HTQ and measures of posttraumatic stress disorder (PTSD) and depression symptoms. Principal components analysis of HTQ items revealed a 5-component subtype model of trauma that accounted for more item variance than a 1-component solution. These trauma subtypes …

Not Enough Cooks In The Kitchen: An Empirical Test Of A Two-Factor Model Of Work Unit Understaffing, Cristina Keiko Hudson

USF Tampa Graduate Theses and Dissertations

Although most working adults possess a lay understanding of understaffing in the workplace and may, in fact, feel they are experiencing such a stressor, a review of the research literature reveals a general lack of empirical work on understaffing and its consequences. Hudson and Shen (2013, Development and testing of a new measure of understaffing. Paper presented at the Southern Management Association 2013 Meeting, New Orleans, LA) recently proposed a new model of understaffing that distinguished between two types of personnel deficiencies, manpower and expertise shortages, and linked these dimensions to worker well-being and attitudinal outcomes and identified likely mediating …
