Merely Misunderstood: Expressive, Receptive, And Pragmatic Language In Children With Disruptive Behavior Disorders, Monica L. Gremillion Dec 2011

Merely Misunderstood: Expressive, Receptive, And Pragmatic Language In Children With Disruptive Behavior Disorders, Monica L. Gremillion

LSU New Orleans Theses and Dissertations

Children with Disruptive Behavior Disorders (DBD), including Attention-Deficit/Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD) have poorer language skills compared to typically developing children; however, language as a potential risk factor for DBD has received little empirical attention or evaluation. Receptive, expressive, and pragmatic language skills in preschoolers with DBD were examined. Participants were 82 preschool-age children and their primary caregivers. Primary caregivers completed a semi-structured interview and symptom and language questionnaires. Preschoolers completed measures of receptive and expressive language. Results indicated that preschoolers with DBD were more impaired on receptive, expressive, and pragmatic language compared to non-DBD children. Pragmatic …


Factors That Contribute To Susceptibility Of The Placebo/Nocebo Effect In Experimentally Induced Ischemic Arm Pain, Steve T. Brewer Dec 2011

Factors That Contribute To Susceptibility Of The Placebo/Nocebo Effect In Experimentally Induced Ischemic Arm Pain, Steve T. Brewer

LSU New Orleans Theses and Dissertations

Placebo’s (positive expectancies producing positive outcomes) and nocebo’s (negative expectancies producing negative outcomes) are real and measurable effects. Real as these effects may be, predicting individuals that may be susceptible to placebo/nocebo effects has been inconsistent. The present study examined whether measures designed to assess somatization (MSPQ), catastrophizing (PCS) and childhood trauma (CTQ) would predict placebo and nocebo membership. In addition, measures designed to assess anxiety (ASI) anxiety about pain (PASS) and depression (BDI) were evaluated to determine whether anxiety or depression mediates responsiveness. The Hargreaves Thermal Withdrawal test and the submaximal effort tourniquet technique were employed as pain vehicles …


Pain Tolerance And Thresholds In Women With Dyspareunia: Do Pain And Sex Primes Have Differential Effects?, Lea Thaler Dec 2011

Pain Tolerance And Thresholds In Women With Dyspareunia: Do Pain And Sex Primes Have Differential Effects?, Lea Thaler

UNLV Theses, Dissertations, Professional Papers, and Capstones

Dyspareunia, defined as recurrent pain in the genital/pelvic region during sexual intercourse, is one of the most common types of female sexual dysfunction, affecting approximately 15% of women between the ages of 18 and 24. Women with dyspareunia display similar cognitive and emotional styles evidenced in other chronic pain conditions (e.g. hypervigilance for pain information, catastrophization, and negative affect); however, dyspareunia is a unique pain disorder in that it directly involves sexual functioning. This pairing of pain and sex raises the issue of conditioning. Is it possible that because intercourse is painful for women with dyspareunia, the presentation of any …


In Search Of The Neurobiological Substrates For Social Playfulness In Mammalian Brains, Stephen M. Siviy, Jaak Panksepp Oct 2011

In Search Of The Neurobiological Substrates For Social Playfulness In Mammalian Brains, Stephen M. Siviy, Jaak Panksepp

Psychology Faculty Publications

Play behavior is a fundamental and intrinsic neurobehavioral process in the mammalian brain. Using rough-and-tumble play in the juvenile rat as a model system to study mammalian playfulness, some of the relevant neurobiological substrates for this behavior have been identified, and in this review this progress. A primary-process executive circuit for play in the rat that includes thalamic intralaminar nuclei, frontal cortex and striatum can be gleaned from these data. Other neural areas that may interact with this putative circuit include amygdala, ventral hypothalamus, periaqueductal gray (PAG), and deep tectum, as well as ascending dopamine systems which participate in all …


Serotonin, Motivation, And Playfulness In The Juvenile Rat, Stephen M. Siviy, Loren M. Deron, Chelsea R. Kasten Oct 2011

Serotonin, Motivation, And Playfulness In The Juvenile Rat, Stephen M. Siviy, Loren M. Deron, Chelsea R. Kasten

Psychology Faculty Publications

The effects of the selective 5HT1A agonist 8-OH-DPAT were assessed on the play behavior of juvenile rats. When both rats of the test pair were comparably motivated to play, the only significant effect of 8-OH-DPAT was for play to be reduced at higher doses. When there was a baseline asymmetry in playful solicitation due to a differential motivation to play and only one rat of the pair was treated, low doses of 8-OH-DPAT resulted in a collapse of asymmetry in playful solicitations. It did not matter whether the rat that was treated initially accounted for more nape contacts or fewer …


Picture Recognition Of Food By Macaques (Macaca Silenus), Peter G. Judge Sep 2011

Picture Recognition Of Food By Macaques (Macaca Silenus), Peter G. Judge

Faculty Journal Articles

Pictorial representations of three-dimensional objects are often used to investigate animal cognitive abilities; however, investigators rarely evaluate whether the animals conceptualize the two-dimensional image as the object it is intended to represent. We tested for picture recognition in lion-tailed macaques by presenting five monkeys with digitized images of familiar foods on a touch screen. Monkeys viewed images of two different foods and learned that they would receive a piece of the one they touched first. After demonstrating that they would reliably select images of their preferred foods on one set of foods, animals were transferred to images of a second …


The Effects Of Rumination, Hostility, And Distraction On Cardiovascular Reactivity And Recovery From Anger Recall In Healthy Women, Meghan K. Mclain Jul 2011

The Effects Of Rumination, Hostility, And Distraction On Cardiovascular Reactivity And Recovery From Anger Recall In Healthy Women, Meghan K. Mclain

Psychology Theses & Dissertations

Cardiovascular reactivity and recovery following an emotional stressor may play a crucial role in mediating the relation between psychosocial factors (e.g. hostility and anger) and cardiovascular disease. Hostility has been associated with trait rumination. Trait rumination, a tendency to focus attention on negative thoughts and emotions and be prone to feelings of revenge, is not adequately captured in current measures of hostility. The current study examined whether trait rumination, indexed by the Dissipation-Rumination Scale, has an independent effect of increasing cardiovascular reactivity and prolonging cardiovascular recovery from angry events above and beyond hostility as measured by the Cook-Medley Hostility Scale. …


Dysfunctional Play And Dopamine Physiology In The Fischer 344 Rat, Stephen M. Siviy, Cynthia A. Crawford, Garnik Akopian, John P. Walsh Jul 2011

Dysfunctional Play And Dopamine Physiology In The Fischer 344 Rat, Stephen M. Siviy, Cynthia A. Crawford, Garnik Akopian, John P. Walsh

Psychology Faculty Publications

Juvenile Fischer 344 rats are known to be less playful than other inbred strains, although the neurobiological substrate(s) responsible for this phenotype is uncertain. In the present study, Fischer 344 rats were compared to the commonly used outbred Sprague-Dawley strain on several behavioral and physiological parameters in order to ascertain whether the lack of play may be related to compromised activity of brain dopamine (DA) systems. As expected, Fischer 344 rats were far less playful than Sprague-Dawley rats, with Fischer 344 rats less likely to initiate playful contacts with a playful partner and less likely to respond playfully to these …

Psychology and Child Development

To understand the relationship between BMI and sleep patterns in Cal Poly Freshman (First years) over the course of their first year at Cal Poly. First year students were recruited via campus email to fill out a survey regarding various health aspects. The survey was filled out at the beginning of the year (Fall 2009), and again in June (Spring 2010). The questions used in this study only pertained to height, weight, sleep quantity, and sleep quantity satisfaction rating. The results were not significant for the cross sectional analysis of the Fall 2009 sample and the Spring 2010 sample. The …


How Sweet Is It, Really? The Anomalous Effects Of Glucose At Retrieval, Sarah A. Gillott May 2011

How Sweet Is It, Really? The Anomalous Effects Of Glucose At Retrieval, Sarah A. Gillott

Undergraduate Honors Thesis Collection

151 participants gave free recall and probed response memories for best kisses and The Lion King. Blood-glucose levels were manipulated at retrieval with glucose (50g) or saccharin (35mg) in the form of a lemonade drink. Memories for best kisses were more elaborate than memories for The Lion King. This may be due to the fact that best kiss memories were rated as more arousing than film memories. Regardless, high blood-glucose levels as a result of glucose consumption significantly impaired autobiographical kiss memory, yet enhanced semantic memory for The …


Diel Periodicity In Activity And Location In The Web Of The Common House Spider (Achaearanea Tepidariorum)., Elise Wolf May 2011

Diel Periodicity In Activity And Location In The Web Of The Common House Spider (Achaearanea Tepidariorum)., Elise Wolf

Undergraduate Honors Theses

Circadian rhythm is a type of endogenous clock that controls daily behavioral patterns in most organisms. Spiders have been shown to exhibit both circadian and non-circadian rhythms in their behaviors. This rhythmicity may allow spiders to cope with diel changes in environmental conditions. Both diurnal and nocturnal behavior have different sets of costs and benefits to a species’ survival. Achaearanea tepidariorum is one species in which potential circadian rhythmicity has never been studied. Due to its foraging behavior, it was predicted that its daily activity would be arrhythmic. We recorded the positions within the web of forty individuals throughout the …


Time-Dependent Effects Of Stress On Cocaine Conditioned Place Preference Using A Rat Model Of Posttraumatic Stress Disorder, Lily K. Helpenstell May 2011

Time-Dependent Effects Of Stress On Cocaine Conditioned Place Preference Using A Rat Model Of Posttraumatic Stress Disorder, Lily K. Helpenstell

Senior Theses

Posttraumatic Stress Disorder (PTSD) affects approximately 8% of the entire population within their lifetimes. A startling trend of co-occurring PTSD and cocaine use has surfaced among humans who express these disorders. The present study employed the rat model of PTSD, Single Prolonged Stress, to examine the effects of stress on the rewarding properties of cocaine. Place conditioning was used to specifically evaluate differences between animals that had undergone a post-stress delay of conditioning in comparison to animals that were not delayed. This delay before conditioning, or incubation period, is a time spent undisturbed in the home cage for 10-days post-stress …


The Effect Of Early Environmental Manipulation On Locomotor Sensitivity And Methamphetamine Condition Place Preference Reward, Emily Hensleigh May 2011

The Effect Of Early Environmental Manipulation On Locomotor Sensitivity And Methamphetamine Condition Place Preference Reward, Emily Hensleigh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Early life stress has drastic effects on neurological development, affecting health and well-being later in life. Instances of child abuse and neglect are associated with higher rates of depression, risk taking behavior, and an increased risk of drug abuse later in life (Chapman,D.P. 2004; Dube,S.R. 2003). This study used repeated neonatal separation of rat pups as a model of early life stress. Rat pups were either handled and weighed as controls or separated for 180 minutes per day during postnatal days 2-8. In adulthood, rats were tested for methamphetamine conditioned place preference reward and methamphetamine induced locomotor activity. Tissue samples …


Testosterone And Vasopressin In Men’S Reproductive Behavior, Eric T. Steiner May 2011

Testosterone And Vasopressin In Men’S Reproductive Behavior, Eric T. Steiner

UNLV Theses, Dissertations, Professional Papers, and Capstones

One common practice used by researchers is to divide human reproduction into two major domains: mating and parenting. Adaptive problems men faced over the millennia may have produced evolutionary pressure for hormone responses and behavior that facilitate both mating and parenting, either separately or simultaneously. The sometimes competing domains of mating and parenting in men are often mediated by a number of the same hormones, such as testosterone (T) and arginine vasopressin (AVP). One aim of the current study was to examine differences in baseline levels of T and AVP between childless men who were not in an exclusive, romantic …

A two phase pilot study was performed where these conditions were compounded into one and two levels were selected in such a way to create a normal and extreme classroom physical environment. A total of 154 undergraduate UNLV students participated in the two phase pilot laboratory study in which they completed tasks related to reading and listening to an oral presentation of a passage of high density technical …


Debrazza’S Monkeys (Cercopithecus Neglectus) In A Mixed-Taxa Zoo Exhibit: Effects On The Behavior Of A Breeding Group Of Debrazza’S Monkeys After The Birth Of An Infant, Rachel Diamond Apr 2011

Debrazza’S Monkeys (Cercopithecus Neglectus) In A Mixed-Taxa Zoo Exhibit: Effects On The Behavior Of A Breeding Group Of Debrazza’S Monkeys After The Birth Of An Infant, Rachel Diamond

Psychology Honors Projects

Historically, zoos rarely feature mixed taxa exhibits including multiple primate species; the Minnesota Zoo opened such a unique four-species exhibit featuring Rock hyraxes, Red River hogs, Colobus monkeys, and DeBrazza’s monkeys in May, 2010. Because of potential problems associated with territoriality and aggression, primates in mixed-taxa exhibits are generally non-breeding. However, the DeBrazza’s monkeys at the MN Zoo are a breeding pair with a juvenile offspring. The intent of this study was to design an ethogram with the purpose of calculating the effects of a mixed taxa exhibit on the behavior of this breeding group, and to compare their behavior …


Persistence Of One-Trial Cocaine-Induced Behavioral Sensitization And Conditioned Activity In Preweanling Rats, Anthony Michael Cortez Jan 2011

Persistence Of One-Trial Cocaine-Induced Behavioral Sensitization And Conditioned Activity In Preweanling Rats, Anthony Michael Cortez

Theses Digitization Project

The purpose of this thesis was to determine the persistence of one-shot context-specific and context-independent behavioral sensitization by administering a single pretreatment injection of cocaine or saline in either the home cage or a novel test chamber on PD 19 or PD 79. In order to examine the persistence of conditioned activity, adult rats were given an injection of saline after 1, 3, or 5 abstinence days. Preweanling rats were given an injection of saline after only 1 abstinence day.


Medial Prefrontal Modulation Of The Nucleus Basalis Magnocellularis During Attention-Dependent Learning, Venuz Yadira Greenfield Jan 2011

Medial Prefrontal Modulation Of The Nucleus Basalis Magnocellularis During Attention-Dependent Learning, Venuz Yadira Greenfield

Theses Digitization Project

The nucleus basalis magnocellularis (NBM) sends cholinergic projections to the neocortex. While NBM activation of the neocortex regulates attention and contributes to memory formation, the mechanisms controlling NBM activity during attention-dependent learning are not well understood. The current experiment tested the hypothesis that the mPFC is critically involved in modulating NBM activity during attention-dependent learning in rats. A total of 80 male Long-Evans rats were purchased from a commerical research animal vendor. Rats were randomly assigned to one of four controlled groups. The procedures were done by an animal technician and veterinarian in the CSUSB Social and Behavioral Science vivarium …

Despite training and support, many middle school teachers struggle to create, implement, and enforce research-based strategies to manage students' behaviors. The purpose of this case study was to examine teachers' perceptions about the barriers of managing student behavior. The research questions investigated 9 teachers' perceived barriers of managing student behavior at one middle school and the observed actions of these teachers' reactions to student behavior. Each participant was asked to participate in a 45-minute semistructured interview to examine their perceived barriers of managing student behavior and the strategies they use to manage student behavior relative to McGregor's theories X and …


Roles Of Internal Locus Of Control And Self-Efficacy On Managing Job Stressors And Ryff's Six Scales Of Psychological Well-Being, William A. Howatt Jan 2011

Roles Of Internal Locus Of Control And Self-Efficacy On Managing Job Stressors And Ryff's Six Scales Of Psychological Well-Being, William A. Howatt

Walden Dissertations and Doctoral Studies

The purpose of this study was to investigate the roles internal locus of control and self-efficacy play in moderating how employees manage their perceived work stress and positively engage in the behaviors that facilitate autonomy, environmental mastery, personal growth, self-acceptance, positive relations with others, and purpose in life. Investigators have documented the relationship between perceived workplace stress and strain and showed that how employees cope with perceived stress influences their psychological and physical health. However, there is less information available about the relationship between how employees cope with perceived workplace stress and engage in behaviors that facilitate their psychological well-being. …


Self-Hypnosis And Volitional Control Of Finger Temperature Among Adults, Joseph Swope Jan 2011

Self-Hypnosis And Volitional Control Of Finger Temperature Among Adults, Joseph Swope

Walden Dissertations and Doctoral Studies

Raynaud's disease is a condition in which circulation to the hands becomes restricted, causing an uncomfortable sense of cold and occasionally injury. The cause of Raynaud's disease is unknown. Earlier studies have shown that hetero-hypnosis is effective in the treatment of Raynaud's disease. Cost and access to providers limit such a treatment's availability. Theories of hypnosis suggest that self-hypnosis underlies all hypnotic processes. This study examined the utility of self-hypnosis and focused attention on the volitional control of hand temperature. Forty-three adult participants ranging in age from 19 to 77 years with no hypnosis experience were randomly divided into 2 …


The Relationship Between Depression And Cognitive Deterioration In Older Adults, Rakesh Chand Jan 2011

The Relationship Between Depression And Cognitive Deterioration In Older Adults, Rakesh Chand

Walden Dissertations and Doctoral Studies

The population structure of the United States is changing; the older age group is increasing in size relative to the younger generation. The trend is expected to continue, especially starting in 2020, when the baby boomer population---estimated at 80 million---will be reaching their 65 th birthday, a time associated with increasing health complications, including depression and dementia. The study employed a holistic paradigm as the conceptual framework to examine the association between depression and dementia in older adults, and generated a grounded theory to illuminate the relationship between depression and dementia. This theory was then used to assess the efficacy …


Attachment, Parentally Bereaved Adolescents, And High School Outcomes In A Large Inner-City High School, Silvana Amar Jan 2011

Attachment, Parentally Bereaved Adolescents, And High School Outcomes In A Large Inner-City High School, Silvana Amar

Walden Dissertations and Doctoral Studies

U.S. and world communities face the challenges of understanding how children grieve and of giving them sufficient social and educational support. Inner-city minority adolescents have not been represented well in the bereavement and attachment literature. The purpose of the quantitative study was to use the attachment theory to understand the impact of parental bereavement on these adolescents. Data were collected using the Adult Attachment Interview (AAI), the Piers-Harris Children's Self- Concept Scale (2nd ed.), and school records. MANOVAs were used to analyze the influence of attachment organization, bereavement status, and gender on self-concept and academic and behavioral functioning in school. …


Implementing Core Values In The High-Tech Industry, Arthur J. Smith Jan 2011

Implementing Core Values In The High-Tech Industry, Arthur J. Smith

Walden Dissertations and Doctoral Studies

Previous research has indicated that the path-goal theory is an effective way to study leadership behavior; however, a gap exists in the literature with respect to its achievement-oriented and participative leadership dimensions in high-tech organizations. In this quantitative study, the effects of a core values intervention on the four leadership dimensions of House's path-goal theory were evaluated at a semiconductor manufacturer with a focus on the differences between supervisors and non-supervisory personnel. Data were gathered from the validated, company-developed Corporate Culture Survey that was administered pre and post intervention. Data were also gathered from a categorization task that sorted the …

The problem addressed in this study is that little action is taken to create the social aspects and social value of knowledge-sharing culture within organizations. There is a need for increased understanding of the behavioral side of knowledge management. The purpose of this study was to focus on knowledge sharing from a behavioral perspective. Knowledge management is defined as the accumulation, protection, and leverage of knowledge. This research study investigated the relationship between knowledge sharing and competitiveness and approached the field of knowledge management from the organizational, cultural, and behavioral perspectives. The research questions examined how knowledge workers described the …


Spirituality And Depression In Parents With Children In Oncology Or Hematology Treatment, Kurt D. Soell Jan 2011

Spirituality And Depression In Parents With Children In Oncology Or Hematology Treatment, Kurt D. Soell

Walden Dissertations and Doctoral Studies

The psychological burden of cancer treatment affects not only child patients but also their parents. There is extensive literature on the positive influence of spirituality on the cancer patient. But there is a gap in the literature on the potential healing influence of spirituality on the parent of the cancer or hematology patient. The purpose of this study was to examine the relationship between spirituality and parents' levels of depression and anxiety during their child's hematological or oncology treatment. Using the transtheoretical model of change, a purposive sample of 48 parents of children undergoing cancer or hematology treatment completed a …


Short-Term Nicotine Abstinence And Decision Making, Gabriel D. Searcy Jan 2011

Short-Term Nicotine Abstinence And Decision Making, Gabriel D. Searcy

Dissertations

Research has shown that acute drug administration may affect impulsivity (i.e., choice for small, immediate rewards over large, delayed rewards) on laboratory delay-discounting tasks. Few studies have investigated how drug abstinence affects impulsivity. Investigating how drug abstinence affects impulsivity may be relevant to preventing relapse. Two previous studies have investigated the effects of short-term nicotine abstinence on impulsivity using delay-discounting tasks. The results were mixed, one study suggested that choices became more impulsive (i.e., delayed money was devalued) under nicotine deprivation. One goal of the present research was to further investigate how nicotine deprivation affects delay-discounting for money rewards. In …
