Developing And Selecting Auditory Warnings For A Real-Time Behavioral Intervention, John Belletierre, Suzanne C. Hughes, Sandy Liles, Marie Boman-Davis, Neil E. Klepeis, Elaine Blumberg, Jeff Mills, Vincent Berardi, Saori Obayashi, T. Tracy Allen, Melbourne F. Hovell

Psychology Faculty Articles and Research

Real-time sensing and computing technologies are increasingly used in the delivery of real-time health behavior interventions. Auditory signals play a critical role in many of these interventions, impacting not only behavioral response but also treatment adherence and participant retention. Yet, few behavioral interventions that employ auditory feedback report the characteristics of sounds used and even fewer design signals specifically for their intervention. This paper describes a four-step process used in developing and selecting auditory warnings for a behavioral trial designed to reduce indoor secondhand smoke exposure. In step one, relevant information was gathered from ergonomic and behavioral science literature to …

Eating Disorder Onset In Young Girls: A Longitudinal Trajectory Analysis, Carolyn M. Pearson

Theses and Dissertations--Psychology

To investigate whether there are different patterns of development for binge eating and purging behavior among pre-adolescent and early adolescent girls, I conducted trajectory analyses of those behaviors in 938 girls across eight waves of data from the spring of 5^th grade (the last year of elementary school) through the spring of 9^th grade (the first year of high school). Analyses revealed four separate developmental trajectories for binge eating behavior (labeled none, increasing, decreasing, and high steady) and three separate developmental trajectories for purging behavior (labeled none, dabble, and increasing). Fifth grade scores on risk factors that were …

Big Five Personality Traits, Pathological Personality Traits, And Psychological Dysregulation: Predicting Aggression And Antisocial Behaviors In Detained Adolescents, Katherine S. L. Lau

LSU New Orleans Theses and Dissertations

This study tested the utility of three different models of personality, namely the social and personality model, the pathological personality traits model, and the psychological dysregulation model, in predicting overt aggression, relational aggression, and delinquency in a sample of detained boys (ages 12 to 18; M age = 15.31; SD = 1.16). Results indicated that the three personality approaches demonstrated different unique associations with aggression and delinquency. The psychological dysregulation approach, composed of behavioral dysregulation, emotional dysregulation, and cognitive dysregulation, emerged as the overall best predictor of overt aggression, relational aggression, and delinquency. After controlling for the Big Five personality …

Reimagining My Body, Center For Public Service

SURGE

I stood there, shoulders slouched, elbows locked, hands glued to the side of the toilet. My body convulsing, I told myself, “this is the last time, just one more time and you’ll get back on track tomorrow.” It wasn’t the last time. I had been forcing myself to purge for months at this point, and each time I hated myself for it.

It was something I couldn’t control. It wasn’t out of a need for attention as so commonly thought, but a pure need to be the unreachable level of thin that I thought would make me beautiful. I was …

Predeliberation Activity In Prefrontal Cortex And Striatum And The Prediction Of Subsequent Value Judgment, Uri Maoz, Ueli Rutishauser, Soyoun Kim, Xinying Cai, Christof Koch

Psychology Faculty Articles and Research

Rational, value-based decision-making mandates selecting the option with highest subjective expected value after appropriate deliberation. We examined activity in the dorsolateral prefrontal cortex (DLPFC) and striatum of monkeys deciding between smaller, immediate rewards and larger, delayed ones. We previously found neurons that modulated their activity in this task according to the animal's choice, while it deliberated (choice neurons). Here we found neurons whose spiking activities were predictive of the spatial location of the selected target (spatial-bias neurons) or the size of the chosen reward (reward-bias neurons) before the onset of the cue presenting the decision-alternatives, and thus before rational deliberation …

Prenatal Development: Annotated Bibliography, Victoria J. Molfese, Amanda Prokasky, Kathleen Moritz Rudasill, Ibrahim H. Acar, Xiaoqing Tu, Kate Sirota, Brian Keiser

Department of Child, Youth, and Family Studies: Faculty Publications

For decades, researchers have investigated how events in the prenatal period impact women and their infants. These studies, particularly by researchers in the medical, neuroscience, and behavioral science fields, led to discoveries of important information regarding the prenatal events that were strongly associated with mortality (or death) and morbidity (or incidences of injury, pathology and abnormalities/anomalies, and neurobehavioral sequelae) in the neonatal and infancy periods. Among the many common findings from early research studies, two are particularly noteworthy. First, maternal and fetal risk conditions arising in the prenatal period do not do so in isolation. Sameroff and Chandler characterized this …

Sex Differences In White Matter Development During Adolescence: A Dti Study, Yingying Wang, Chris Adamson, Weihong Yuan, Mekibib Altaye, Anna W. Byars, Scott K. Holland

Center for Brain, Biology, and Behavior: Faculty Publications

Adolescence is a complex transitional period in human development, composing physical maturation, cognitive and social behavioral changes. The objective of this study is to investigate sex differences in white matter development and the associations between intelligence and white matter microstructure in the adolescent brain using diffusion tensor imaging (DTI) and tract-based spatial statistics (TBSS). In a cohort of 16 typically-developing adolescents aged 13 to 17 years, longitudinal DTI data were recorded from each subject at two time points that were one year apart. We used TBSS to analyze the diffusion indices including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity …

Do Interactions Between Motor And Visual Codes Facilitate Visuospatial Memory?: The Influence Of Action On Memory Performance: When Does It Help You, When Does It Hurt You, Michael Dodd

Discipline-Based Education Research Group Speaker Series

One of the hallmarks of human cognition is that we have a limited number of cognitive resources available and successful performance in the environment requires an appropriate number of these resources to be directed towards one's primary task. As such, it is unsurprising that when attention is divided between two tasks simultaneously, performance on each task suffers relative to if each task was done in isolation. At the same time, however, it has also been shown that when individuals process information in multiple ways (e.g. across more than one modality) that performance is enhanced. In the present talk I will …

Combined Erp/Fmri Evidence For Early Word Recognition Effects In The Posterior Inferior Temporal Gyrus, Joseph Dien, Eric S. Brian, Dennis L. Molfese, Brian T. Gold

Center for Brain, Biology, and Behavior: Faculty Publications

Two brain regions with established roles in reading are the posterior middle temporal gyrus and the posterior fusiform gyrus. Lesion studies have also suggested that the region located between them, the posterior inferior temporal gyrus (pITG), plays a central role in word recognition. However, these lesion results could reflect disconnection effects since neuroimaging studies have not reported consistent lexicality effects in pITG. Here we tested whether these reported pITG lesion effects are due to disconnection effects or not using parallel ERP/fMRI studies. We predicted that the Recognition Potential (RP), a left-lateralized ERP negativity that peaks at about 200–250 ms, might …

Transient Measurement Error In A Diverse Population, Sean Potter

Collection of Engaged Learning

The assessment of personality has important implications for clinicians, personality researchers, and the workplace setting. The accurate assessment of personality is therefore crucial to these various fields. However, measurement error has not had the necessary attention it deserves. In particular, the effect of transient measurement error on personality assessment has only begun to be recently studied. Furthermore, only undergraduate samples of relatively homogenous studies have been examined. The purpose of this study was to examine the impact of transient error for personality assessment in an older, more diverse population. Participants completed a test-retest study across a time frame (1 week) …

The Flexible Fairness: Equality, Earned Entitlement, And Self-Interest, Chunliang Feng, Yi Luo, Ruolei Gu, Lucas S. Broster, Xueyi Shen, Tengxiang Tian, Yue-Jia Luo, Frank Krueger

Behavioral Science Faculty Publications

The current study explored whether earned entitlement modulated the perception of fairness in three experiments. A preliminary resource earning task was added before players decided how to allocate the resource they jointly earned. Participants' decision in allocation, their responses to equal or unequal offers, whether advantageous or disadvantageous, and subjective ratings of fairness were all assessed in the current study. Behavioral results revealed that participants proposed more generous offers and showed enhanced tolerance to disadvantageous unequal offers from others when they performed worse than their presumed "partners," while the reverse was true in the better-performance condition. The subjective ratings also …

Sensory-Specific Appetition: Postingestive Detection Of Glucose Rapidly Promotes Continued Consumption Of A Recently Encountered Flavor, Kevin P. Myers, Marisa S. Taddeo, Emily K. Richards

Faculty Journal Articles

It is generally thought that macronutrients stimulate intake when sensed in the mouth (e.g., sweet taste) but as food enters the GI tract its effects become inhibitory, triggering satiation processes leading to meal termination. Here we report experiments extending recent work (see [1]) showing that under some circumstances nutrients sensed in the gut produce a positive feedback effect, immediately promoting continued intake. In one experiment, rats with intragastric (IG) catheters were accustomed to consuming novel flavors in saccharin daily while receiving water infused IG (5 ml/15 min). The very first time glucose (16% w/w) was infused IG instead of water, …

Deficits In Retrospective And Prospective Components Underlying Prospective Memory Tasks In Amnestic Mild Cognitive Impairment, Ting Zhou, Lucas S. Broster, Yang Jiang, Feng Bao, Huali Wang, Juan Li

Behavioral Science Faculty Publications

OBJECTIVES: By use of purer indices of PM and RM components than previous studies and adoption of three PM task types, the present study aimed to investigate the deficits of these two components underlying global impairment at a PM task in individuals with amnestic mild cognitive impairment (aMCI).

METHODS: Nineteen aMCI patients and 22 normal controls were examined on event-, time- and activity-based PM tasks. Separate scores were obtained for initiation of intentions (i.e. PM component) and for the content of the intentions (i.e. RM component).

RESULTS: Individuals with aMCI achieved lower PM component (but not RM component) scores than …

Network Dynamics Of Visual Naming, Christopher R. Conner

Dissertations and Theses (Open Access)

Recognition and naming of objects and actions are fundamental components of language. They involve several different systems working in coordination to accomplish a complex behavior. During visual naming, sensory and semantic processing are carried out by dedicated cortical substrates in the temporal and occipital lobes, while response selection and articulatory planning are handled by prefrontal cortex. Despite decades of research using lesion analysis, functional MRI and electro-encephalography, the precise dynamics involved remain unknown due to the inadequate spatio-temporal resolution of these methodologies. Of particular interest is the organization of semantic knowledge and the degree of serial and parallel organization of …

Treatment Of Psychiatric Inpatients With Relationship Dysfunction Using A Short Term Cognitive Interpersonal Intervention: A Pilot Study, Tamra Rasberry

Doctoral Dissertations and Projects

Relationship conflict for the psychiatric patient can have significant detrimental effects. There are specific types of interactions that can increase conflict and predict the potential for relapse; these have been identified by research and designated as components of Expressed Emotion (EE). Cognitive Behavioral Therapy (CBT) and Interpersonal Therapy (IPT) have been very effective when targeting specific psychiatric diagnoses, but less effective when addressing relationship conflict. The majority of studies addressing relationship conflict have taken place in an outpatient, long-term setting. There is limited research that utilizes an inpatient short-term intensive therapy with relationship conflict as its sole focus, targeting areas …

Restoring Effort-Related Functions In Models Of Depression Symptoms: Reversing Fatigue Symptoms Induced By Catecholamine Depleting Agent Tetrabenazine With The Adenosine A2a Antagonist Msx-3, Charlotte Freeland

Honors Scholar Theses

Motivational symptoms related to effort expenditure have been associated with major depression and other disorders that afflict millions of individuals worldwide. In an effort to identify potential therapeutic agents and characterize the underlying biochemical mechanisms related to these behaviors, recent research has utilized animal models to study and characterize such behavior. Previous work in the Salamone lab produced evidence that rats with impaired dopamine (DA) transmission show changes in response allocation in tasks that measure effort-related choice behavior, which are characterized by a decrease in selection of the high-effort choice but increased selection of the low-effort alternative. The present work …

Beliefs About Complementary And Alternative Medicine In Hiv-Infected Black Women Using The Theory Of Planned Behavior, Stephanie G. Lino

While prevention remains, a major effort targeting treatment efficacy and modalities for this sub-group need to be better understood.

Purpose. The purpose of this study is to assess whether HIV-positive Black women’s attitudes, subjective norms and perceived behavioral control are related to intention of dietary supplements and spiritual practices use in their HIV treatment.

Method. In phase one, Grounded Theory methods (N= …

Early Life Stress, Drug Abuse, Exercise Effects On Bdnf And Sex-Influenced Excercise Differences, Karissa Dold

Honors College Theses

In 2011, the U.S. reported 3 million child maltreatment cases, an uncomfortably high but recurring figure each year. Research shows exposure to early life stress (ELS) increases an individual’s susceptibility to substance abuse, specifically of nicotine, alcohol, and cocaine. Increased susceptibility may result from dysregulation of the HPA axis sustaining activation into adulthood after ELS. Hyperactivation of the HPA axis significantly reduces hippocampal BDNF, a neurotrophin involved in neuronal growth and plasticity. Reduced hippocampal BDNF may be a factor in substance abuse vulnerability. Additionally, research shows exercise protects hippocampal BDNF from stress induced down-regulation. To explore these relationships, this study …
