A Rat Model Of Mild Blast-Induced Head Trauma With Structural And Biochemical Abnormalities In The Absence Of Motor Deficits, Michael Kelso Walls

Open Access Theses

Blast injury has been coined the "signature injury of the Iraq war" resulting in a surge of interest in understanding and addressing the corresponding pathological sequelae. As modern warfare develops into a distinctly guerrilla style combat by smaller terrorist groups against larger, regimented forces, tactics like suicide bombing and roadside bombing with Improvised Explosive Devices (IEDs) become more prevalent. 1,2 This increased use of IEDs countered with improved body armor and protective technologies has significantly increased the survival rate of such attacks. 1.2 However, as survival rates have improved with body armor and other protective technologies, the incidence of reported …

Consumer Perceptions Of Child-Friendly Shaped Healthy Fruit And Vegetable Snacks, Selena Lauren Baker

Open Access Theses

Fruits and vegetables (FV) are widely recognized as healthful foods by the public, and most individuals are aware of dietary guidance recommendations to consume more FV. However, actual consumption of FV has been and continues to be low in the United States and many other countries, despite public health efforts to change this trend. The sub-optimal intake of FV among children and adolescents is of particular concern due to high nutrient requirements for proper growth and development during these life stages. Fruit and vegetable intake patterns in childhood have been shown to track into later life and may affect individuals' …

Delayed Match-To-Sample In Preschool Children, Thomas Ratkos

Masters Theses

In delayed match-to-sample (DMTS) tasks, a sample stimulus is shown and then removed for some period of time before comparison stimuli are presented. Joint control theory (Lowenkron, 1984, 1988, 1991, 1998, 2006) explains correct selections on delayed match-to-sample tasks in terms of the joint control of behavior by the comparison stimulus and a repeated word or words originating from the sample stimulus. Eight children ages 3 to 6 were exposed to a DMTS task with visual stimuli using a 15s delay. During training, children were taught to name the stimulus cards and then repeat the name of the target stimulus …

Long-Lasting Sensitization Induced By Repeated Risperidone Treatment In Adolescent Sprague-Dawley Rats: A Possible D2 Receptor Mediated Phenomenon?, Jing Qiao, Jun Gao, Qing Shu, Qinglin Zhang, Gang Hu, Ming Li

Department of Psychology: Faculty Publications

Rationale Risperidone use in children and adolescents for the treatment of various neuropsychiatric disorders (e.g., schizophrenia, autism, disruptive behavior, etc.) has increased substantially in recent decades. However, its long-term effect on the brain and behavioral functions is not well understood. Objective The present study investigated how a short-term risperidone treatment in adolescence impacts antipsychotic response in adulthood in the conditioned avoidance response and phencyclidine (PCP)-induced hyperlocomotion tests. Methods Male adolescent Sprague-Dawley rats (postnatal days [P] 40–44 or 43–48) were first treated with risperidone (0.3, 0.5, or 1.0 mg/kg, subcutaneously (sc)) and tested in the conditioned avoidance or PCP (3.2 mg/kg, …

Juvenile Diversion Programs: High-Risk Youth And Their Effect On Offense Targeting, Chelsey R. Warner

Political Science Theses and Capstones

One of the largest problems that plague the juvenile justice system today is how to better handle juvenile crime without causing the juvenile to revert back to that behavior, but still helping them understand and acknowledge the crime they have committed. The state of Minnesota has created juvenile diversion programs as an attempt to aid in that endeavor. These programs however are under researched. The goal of this article is to shed some light on what those programs look like and how some counties programs vary from other programs on other counties; specifically focusing on the variation between offense-targeting for …

Overexpression Of The Steroidogenic Enzyme Cytochrome P450 Side Chain Cleavage In The Ventral Tegmental Area Increases 3 ,5 -Thp And Reduces Long-Term Operant Ethanol Self-Administration, Jason B. Cook, David F. Werner, Antoniette Maldonado-Devincci, Maggie N. Leonard, Kristen R. Fisher, Todd K. O'Buckley, Patrizia Porcu, Thomas J. Mccown, Joyce Besheer, Clyde Hodge, A.Leslie Morrow

Psychology Faculty Scholarship

Neuroactive steroids are endogenous neuromodulators capable of altering neuronal activity and behavior. In rodents, systemic administration of endogenous or synthetic neuroactive steroids reduces ethanol self-administration. We hypothesized this effect arises from actions within mesolimbic brain regions that we targeted by viral gene delivery. Cytochrome P450 side chain cleavage (P450scc) converts cholesterol to pregnenolone, the rate-limiting enzymatic reaction in neurosteroidogenesis. Therefore, we constructed a recombinant adeno-associated serotype 2 viral vector (rAAV2), which drives P450scc expression and neuroactive steroid synthesis. The P450scc-expressing vector (rAAV2-P450scc) or control GFP-expressing vector (rAAV2-GFP) were injected bilaterally into the ventral tegmental area (VTA) or nucleus accumbens (NAc) …

Auditory Information In The Form Of A Scratching Sound Enhances The Effects Of The Rubber Hand Illusion, Bridget O'Mera

Honors Theses

The body schema describes an internal representation of the body in space, and is generated from a number of different sense modalities such as vision and proprioception. Botvinick and Cohen's rubber hand illusion (1998) demonstrates the relative contributions of vision, tactile perception and proprioception to body awareness. In this illusion, a participant's real hand is concealed from view and a prosthetic rubber hand is seen in its place. An experimenter simultaneously administers tactile stimulation to both the seen rubber hand and participant's actual hidden hand. The combination of this visual and tactile information overrides proprioceptive cues to body perception, creating …

Impulsive Choice In Unmedicated And Medicated Children Diagnosed With Adhd: Examining The Variables Of Reward Type And Adhd Subtype, Nicole Henriksen

Dissertations

Developmentally inappropriate and impairing impulsive behaviors are often seen in attention-deficit/hyperactivity disorder (ADHD). One method for objectively assessing impulsivity is the Choice-Delay Task (C-DT) which presents repeated opportunities to choose between a smaller, sooner (SS) or larger, later (LL) reward. A preference for the SS reward that results in less total reward is considered impulsive. Many studies have found that participants diagnosed with ADHD choose the SS reward more than typical controls. However, less is known about the effects of different types of rewards, or the comparative performance of certain subgroups, such as children diagnosed with ADHD Predominantly Inattentive Type …

The Effect Of Color On Emotions In Animated Films, Andrew Kennedy

Open Access Theses

Lighting color in animated films is usually chosen very carefully in order to portray a specific mood or emotion. Artists follow conventional techniques with color choices with the intention to create a greater emotional response in the viewer. This study examined the relationship between color variations in videos and emotional arousal as indicated by physiological response. Subjects wore a galvanic skin response (GSR) sensor and watched two different videos: one portraying love and one portraying sadness. The videos were watched multiple times, each with variations in the lighting color. No significant effects on emotion for either hue or saturation were …

Both attractiveness judgements and mate preferences vary considerably cross-culturally. We investigated whether men's preference for femininity in women's faces varies between 28 countries with diverse health conditions by analysing responses of 1972 heterosexual participants. Although men in all countries preferred feminized over masculinized female faces, we found substantial differences between countries in the magnitude of men's preferences. Using an average femininity preference for each country, we found men's facial femininity preferences correlated positively with the health of the nation, which explained 50.4% of the variation among countries. The weakest preferences for femininity were found in Nepal and strongest in Japan. …

Stressor-Induced Increase In Muscle Fatigability Of Young Men And Women Is Predicted By Strength But Not Voluntary Activation, Manda L. Keller-Ross, Hugo M. Pereira, Jaclyn Pruse, Tejin Yoon, Bonnie A. Schlinder-Delap, Kristy A. Nielson, Sandra K. Hunter

Psychology Faculty Research and Publications

This study investigated mechanisms for the stressor-induced changes in muscle fatigability in men and women. Participants performed an isometric-fatiguing contraction at 20% maximal voluntary contraction (MVC) until failure with the elbow flexor muscles. Study one (n = 55; 29 women) involved two experimental sessions: 1) a high-stressor session that required a difficult mental-math task before and during a fatiguing contraction and 2) a control session with no mental math. For some participants (n = 28; 14 women), cortical stimulation was used to examine mechanisms that contributed to muscle fatigability during the high-stressor and control sessions. Study two …

Goats Excel At Learning And Remembering A Highly Novel Cognitive Task, Elodie F. Briefer, Samaah Haque, Luigi Baciadonna, Alan G. Mcelligott

Sentience Collection

Introduction: The computational demands of sociality (maintaining group cohesion, reducing conflict) and ecological problems (extractive foraging, memorizing resource locations) are the main drivers proposed to explain the evolution cognition. Different predictions follow, about whether animals would preferentially learn new tasks socially or not, but the prevalent view today is that intelligent species should excel at social learning. However, the predictions were originally used to explain primate cognition, and studies of species with relatively smaller brains are rare. By contrast, domestication has often led to a decrease in brain size, which could affect cognition. In domestic animals, the relaxed selection pressures …

Gene Co-Citation Networks Associated With Worker Sterility In Honey Bees., Emma Kate Mullen, Mark Daley, Alanna Gabrielle Backx, Graham James Thompson

Brain and Mind Institute Researchers' Publications

BACKGROUND: The evolution of reproductive self-sacrifice is well understood from kin theory, yet our understanding of how actual genes influence the expression of reproductive altruism is only beginning to take shape. As a model in the molecular study of social behaviour, the honey bee Apis mellifera has yielded hundreds of genes associated in their expression with differences in reproductive status of females, including genes directly associated with sterility, yet there has not been an attempt to link these candidates into functional networks that explain how workers regulate sterility in the presence of queen pheromone. In this study we use available …

What Does Performance Theory Have To Teach Us About The Treatment Of Severe And Persistent Mental Illness (Spmi) In Prison?, Kaley Joanne Raskin

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Deinstitutionalization of psychiatric hospitals, which occurred in the 1970's, led to an overwhelming number of mentally ill individuals within jails and prisons. In fact, correctional facilities have become the mainline providers of mentally ill inmates; however, these facilities' primary form of intervention is psychotropic medication. Although beneficial in some instances, when viewed through the lens of Goffman's theories of performance and stigma, simply providing medication promotes the role of mental patient. Arguably, within correctional facilities, medication management assists in maintaining security in the institution (i.e., external change); however, this prohibits the inmate from internal change, which might otherwise be facilitated …

Swing Dancing Along The Spectrum: A Proposed Unique Adjunctive Treatment Approach For Individuals With Autism Spectrum Disorder, Alia Mulder-Rosi

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Autism Spectrum Disorder (ASD) is a class of developmental disorders typically diagnosed during childhood. ASD is characterized by social deficits and repetitive behavioral patterns, which cause clinically significant impairment and are not better explained by intellectual disability (American Psychiatric Association, 2013). This doctoral paper proposes swing dancing as an adjunctive treatment option for high functioning adults with ASD. Swing dance is a category of social, partner dance initially set to swing style jazz music. This category most notably includes Lindy Hop, Charleston, Jitterbug and Balboa. Swing dance is an activity which grants social structure, is typically surrounded by an accepting …

Exploring Emotions Using Invasive Methods: Review Of 60 Years Of Human Intracranial Electrophysiology, Sean A. Guillory, Krzysztof A. Bujarski

Dartmouth Scholarship

Over the past 60 years, human intracranial electrophysiology (HIE) has been used to characterize seizures in patients with epilepsy. Secondary to the clinical objectives, electrodes implanted intracranially have been used to investigate mechanisms of human cognition. In addition to studies of memory and language, HIE methods have been used to investigate emotions. The aim of this review is to outline the contribution of HIE (electrocorticography, single-unit recording and electrical brain stimulation) to our understanding of the neural representations of emotions. We identified 64 papers dating back to the mid-1950s which used HIE techniques to study emotional states. Evidence from HIE …

Intravenous Ghrelin Administration Increases Alcohol Craving In Alcohol-Dependent Heavy Drinkers: A Preliminary Investigation, Lorenzo Leggio, William H. Zywiak, Samuel R. Fricchione, Steven M. Edwards, Suzanne M. De La Monte, Robert M. Swift, George A. Kenna

Department of Psychology: Faculty Publications

Background: There is a need to identify novel pharmacologic targets to treat alcoholism. Animal and human studies suggest a role for ghrelin in the neurobiology of alcohol dependence and craving. Here, we were the first to test the hypothesis that intravenous administration of exogenous ghrelin acutely increases alcohol craving.

Methods: This was a double-blind, placebo-controlled human laboratory proof-of-concept study. Nontreatment-seeking, alcoholdependent, heavy-drinking individuals were randomized to receive intravenous ghrelin 1 mcg/kg, 3 mcg/kg or 0 mcg/kg (placebo), followed by a cue-reactivity procedure, during which participants were exposed to neutral (juice) and alcohol cues. The primary outcome variable was the increase …

The Student Augustinian Values Institute: Assessing Its Impact Of Enhancing The Understanding And Experience Of The Augustinian Core Values Of Veritas, Unitas, And Caritas Upon Students In Augustinian Secondary Schools, Stephen M. Curry

Seton Hall University Dissertations and Theses (ETDs)

Educational leadership understands the importance of teaching values in its schools and incorporates this philosophy into the school’s symbolic and structural systems. Roman Catholic Church leaders have always endorsed the teaching of values in its schools and this position was sanctioned at its Second Vatican Council (Vatican Council II, 1962-65). One aspect of the Council emphasized the importance of Catholic education as an essential vehicle for proclaiming the Good News of Jesus Christ. Catholic schools founded and sponsored by religious communities were challenged to reappropriate their founders’ charisms in their educational ministries. The Order of St. Augustine is an example …

Who Is Most Vulnerable To Social Rejection? The Toxic Combination Of Low Self-Esteem And Lack Of Negative Emotion Differentiation On Neural Responses To Rejection, Todd B. Kashdan, C. Nathan Dewall, Carrie L. Masten, Richard S. Pond Jr., Caitlin Powell, David Combs, David R. Schurtz, Antonina S. Farmer

Psychology Faculty Publications

People have a fundamental need to belong that, when satisfied, is associated with mental and physical well-being. The current investigation examined what happens when the need to belong is thwarted—and how individual differences in self-esteem and emotion differentiation modulate neural responses to social rejection. We hypothesized that low self-esteem would predict heightened activation in distress-related neural responses during a social rejection manipulation, but that this relationship would be moderated by negative emotion differentiation—defined as adeptness at using discrete negative emotion categories to capture one's felt experience. Combining daily diary and neuroimaging methodologies, the current study showed that low self-esteem and …

Sustainable Faith: How The Neuroscience Of Emotion Promotes Spiritual Transformation, Christine M. Mutch

Doctor of Ministry

Current research indicates that well-intentioned practices and programs aimed at forming people into the image of Christ are not producing the intended results. One roadblock is the misunderstanding and lack of value placed on the role of emotion in the transformation process. The purpose of this dissertation is to present neuroscience research about the integral role of emotion in one's life, and suggest practical ways to capitalize on emotion to effect transformation.

Chapter one describes the goals of spiritual formation, in contrast to current attitudes and practices of those inside and outside the church. It provides a basic introduction to …

Fallow Bucks Attend To Vocal Cues Of Motivation And Fatigue, Benjamin J. Pitcher, Elodie F. Briefer, Elisabetta Vannoni, Alan G. Mcelligott

Sentience Collection

Vocalizations encode a range of information about the caller, and variation in calling behavior and vocal structure may provide listeners with information about the motivation and condition of the caller. Fallow bucks only vocalize during the breeding season and can produce more than 3000 groans per hour. Males modulate their calling rates, calling faster when other calling males and/or females are nearby. Groans also reveal caller fatigue, becoming shorter and higher pitched toward the end of the rut. Thus, fallow deer groans vary both over very short (minute to minute) and longer timescales (the rut). However, no studies have investigated …

Learning And Memory In The Port Jackson Shark, Heterodontus Portusjacksoni, Tristan L. Guttridge, Culum Brown

Sentience Collection

Basic understanding of the fundamental principles and mechanisms involved in learning is lacking for elasmobranch fishes. Our aim in this study was to experimentally investigate the learning and memory capacity of juvenile Port Jackson sharks, Heterodontus portusjacksoni. Sharks (N = 30) were conditioned over a 19-day period to associate an underwater LED light or stream of air-bubbles [conditioned stimulus (CS)] with a food reward [unconditioned stimulus (US)], using three procedures (delay, trace and control). During experiments, the CS signalled at a random time between 180 and 300 s for 30 s (six times per day). For the delay the US …

Stress-Dependent Opioid And Adrenergic Modulation Of Newly Retrieved Fear Memory, Allen M. Schneider, Peter E. Simson , '78, Caitlin M. Daimon , '11, Jakob Mrozewski , '11, Nicholas M. Vogt , '12, John R. Keefe , '10, Lynn G. Kirby , '89

Psychology Faculty Works

Recent studies on the effect of stress on modulation of fear memory in our laboratory have uncovered endogenous opioid and adrenergic based modulation systems, working in concert, that limit the strengthening or weakening of newly acquired fear memory during consolidation under conditions of mild or intense stress, respectively. The present study sought to determine if similar stress-dependent modulation, mediated by endogenous opioid and adrenergic systems, occurs during reconsolidation of newly retrieved fear memory. Rats underwent contextual fear conditioning followed 24 h later by reactivation of fear memory; a retention test was administered the next day. Stress was manipulated by varying …

Emotional Memory: The Effects Of Temporal Pressure On Episodic Memory, Audrey E. Martinez

Loma Linda University Electronic Theses, Dissertations & Projects

Priority Binding theory (MacKay et al., 2004) proposes that under temporal pressure arousing negative stimuli delay binding of neutral items presented in close temporal proximity (as in lists with mixed neutral and negative stimuli). With fast presentation rates, a subsequent negative item may interrupt the binding process for the preceding neutral stimulus. This results in more accurate memory for negative images presented in mixed lists. However, in slow presentation rates, binding occurs equally for all items. Therefor, no such advantage is predicted comparing images presented in lists of the same valence. This study examined the predictions of priority binding theory …

Levels Of Altruism, Martin Zwick, Jeffrey Alan Fletcher

Complex Systems Faculty Publications and Presentations

The phenomenon of altruism extends from the biological realm to the human socio-cultural realm. This paper sketches a coherent outline of multiple types of altruism of progressively increasing scope that span these two realms and are grounded in an ever-expanding sense of"self." Discussion of this framework notes difficulties associated with altruisms at different levels. It links scientific ideas about the evolution of cooperation and about hierarchical order to perennial philosophical and religious concerns. It offers a conceptual background for inquiry into societal challenges that call for altruistic behavior, especially the challenge of environmental and social sustainability.

The Use Of Play In Speech And Occupational Therapy, Jodi Ehrenkranz, Caroline Laferla

Psychology and Child Development

Sensory Processing Disorder and speech impairment affect millions of children in the United States. Sensory Processing Disorder (SPD) affects a child’s development leading to difficulties with “detecting, modulating, interpreting, and/or organizing sensory stimuli” (Miller, Nielsen & Schoen, 2012, p.804). Furthermore, these children may find it difficult to self-regulate their behavior. Speech impairment is typically described as speech sound disorders (SSD), which involves a child having difficulties with communicating or correctly producing their native language (Brumbaugh, Smit, Nippold & Marinellie, 2013). Brumbaugh et al. (2013) also found that these children were likely to develop a poor self-image which provides even more …

Erwin, William D. Hopkins, A. H. Lewandowski, A. Mudakikwa, Kimberley A. Phillips, Mary Ann Raghanti, Cheryl D. Stimpson, Patrick R. Hof, K. Zilles, Chet C. Sherwood

Psychology Faculty Research

We describe an atypical neuroanatomical feature present in several primate species that involves a fusion between the temporal lobe (often including Heschl's gyrus in great apes) and the posterior dorsal insula, such that a portion of insular cortex forms an isolated pocket medial to the Sylvian fissure. We assessed the frequency of this fusion in 56 primate species (including apes, Old World monkeys, New World monkeys, and strepsirrhines) by using either magnetic resonance images or histological sections. A fusion between temporal cortex and posterior insula was present in 22 species (seven apes, two Old World monkeys, four New World monkeys, …
