Understanding The Motivations Of Rock Climbers: A Social Worlds Study, Amy Miller Ansari

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rock climbing affects public lands through erosion, destruction of vegetation, and disturbance to historical sites. Minimum impact messages can help reduce impacts but requires understanding characteristics of the message recipient. The purpose of this study was to understand the motivations of rock climbers to help land managers design more effective minimum impact messages. This study assesses the motivations of rock climbers using a social worlds approach, focusing on the sub-worlds of. traditional climbers, sport climbers, and boulderers. I found that traditional climbers are most motivated to pursue a wilderness experience, climb in a natural wilderness setting, and climb in quiet …

Comorbid Psychological Disorder In Individuals With Intellectual Disabilities And Autism Spectrum Disorders, Jessica Ann Boisjoli

LSU Master's Theses

Autism spectrum disorders (ASD) are characterized by deficits in three areas of functioning: communication, socialization, and restricted interests/repetitive behavior. With the rise in diagnoses of ASD in recent years, these disorders have received increasing recognition by researchers and clinicians. These efforts have largely been with young children. However, the study of ASD and comorbid disorders in adults with intellectual disability (ID) has been almost nonexistent. While there are measures available to assess comorbid disorders in people with only ID, the differences in adults with ASD and ID and adults with ID alone may also be a good deal different than …

Family Support Within A Child Care Centre: A Case Study, Rikki Maynard

Theses : Honours

This review explored the effects of stress in the family environment and the role that family support plays in reducing this stress. Specifically, research concerning the role that child care workers play in providing support to families who utilise their services was examined. The literature showed that there are many stressors facing families today and that the experience of stress in the family environment can have a detrimental effect on children's developmental outcomes. While the literature showed that experiencing social support can reduce stress in the family environment, it was also found that many families face isolation from such forms …

The Effects Of Food Deprivation On Caffeine And Food Reinforcement In Females, Lauren Baillie

LSU Master's Theses

This study examined the reinforcing value of caffeine and food in a sample of 14 normal-weight females who indicated some degree of dietary restraint, and consumed caffeine daily. Eligible individuals participated in two sessions, one of which required a 24-hour fast. During both sessions, participants completed measures assessing caffeine withdrawal symptoms, urge to drink caffeine, hunger, and a multiple-choice questionnaire (MCQ) requiring them to earn points towards either snack foods or caffeinated beverages. There were no significant differences between the fasting and non-fasting conditions on MCQ scores, though the means were in the predicted direction (i.e., participants appeared to work …

Evaluation Of Three Methods For Teaching Intraverbals To Children With Language Delays, Nicole Trosclair-Lasserre

LSU Doctoral Dissertations

Direct instruction is often necessary to develop language or expand language use in individuals with language delays. Previous research has begun to identify certain training conditions that result in more efficient use of instructional time devoted to language development. Specifically, incorporating mands into the instructional arrangement, increasing the quality of reinforcement delivered for interspersed tasks, and including instructive feedback stimuli into the consequences of learning trials have all demonstrated more efficient learning of targeted language skills. The purpose of the current investigation was to compare three methods for teaching intraverbals (i.e., conversation skills) to individuals with deficits in this area. …

Assessing The Effectiveness Of The Response To Instruction Model For English Language Learners By Utilizing A Non-Language-Based Intervention, Chisato Komatsu

LSU Doctoral Dissertations

The purpose of the current investigation was to examine the use of the Response to Intervention (RTI) model for English Language learners (ELLs) by using a computerized constant time delay procedure (CTD) that de-emphasized the use of language. Forty-five ELLs, 22 native English speakers, and five students with a diagnosis of mild mental retardation participated in the study. A computer-administered CTD procedure was utilized for paired associate tasks. The study found differences and patterns in students’ performances that could be used to differentiate responders and non-responders to intervention. An interesting finding was that once the students were divided into groups …

Television Violence Prevention Versus Juvenile Violence Prevention: Any Connections In Parental Control?, Sharlette Kellum

Contemporary Issues in Juvenile Justice

Animated features, like children's cartoons, are considered by some to be the most violent shows on televi-sion, with approximately 25 to 50 acts of violence per hour (Dietz and Strasburger, 1991). Cartoons, unlike other shows that portray violence, present instances of violence to children in an "acceptable" way, which teaches children from zero to 17 years of age that hurting people is tolerable. Television violence has been linked to juvenile aggression, which has been linked to juvenile violence. In researching several studies, the author found that many of the preventions mentioned in the television violence studies were also mentioned in …

Biographical Study Of A Woman With Agenesis Of The Corpus Callosum: A Story Of Hope And Inspiration, Robin Comerford

PCOM Psychology Dissertations

School psychologists must be knowledgeable about brain development to help students in their care. The human brain has the capability to determine a person's happiness, effectiveness, and positive relationships with others. This biographical study examined how a young woman diagnosed with Agenesis of the Corpus Callosum (ACC) and agenesis of the cerebellum came to live a productive, happy life. ACC is a low incidence form of brain damage marked by inconsistent behavioral and emotional manifestations throughout the lifespan. Personal life artifacts, school documents, and medical records were used to help organize her life experiences in the form of a narrative …

A 65 question electronic survey focusing on four areas: A) training, B) knowledge, C) current practice and D) demographic information, was distributed to 908 certified school psychologists in Pennsylvania and completed by 243 respondents. Results found that school psychologists in Pennsylvania play a key role with assessment and diagnosis of ASD, yet have limited formal training in important aspects of ASD. Doctoral level school psychologists and school psychologists with the greatest number of …

Effects Of Statin Medications On Health Related Behaviors, Stephen M. Timchack

PCOM Psychology Dissertations

The current study focuses on the psychological effects of statin medications. Specifically, this study examines the health related beliefs and behaviors that may be altered by the consumption of this fast acting class of life saving drugs. Although the statin class of medication generally produces favorable physiological results, as evidenced by reduced levels of serum cholesterol, and in some case increases in high density lipoproteins, the health related belief system and heath related behaviors may actually be altered in a negative fashion by engendering a sense of overconfidence; this in turn may alter beliefs and diminish the importance of adhering …

A Phenomenological Study Of Foster Carers' Experiences Of Formal And Informal Support, Tara Cavazzi

Theses : Honours

Foster children are showing a higher prevalence of maladaptive physical and psychosocial issues than ever before. The presence of these issues is predictive of foster placement instability, which is compounded by the inability to recruit and retain foster carers. As placement disruption can have numerous consequences, the factors that influence placement stability have been reviewed. Carer strain is a widespread destabilizing factor, which is augmented by many factors including the perceived level of practical and emotional support from both formal and informal networks. Formal support is linked to placement stability, although carers generally feel undervalued and unappreciated by formal networks. …

Impact Of Comorbidity In Prevention Of Adolescent Depressive Symptoms., Patrick Pössel, Simone Seemann, Martin Hautzinger

Faculty and Staff Scholarship

Despite the well-known relevance of comorbidity, few studies have examined the impact of comorbid anxiety or externalizing symptoms on the prevention of depressive symptoms in adolescents. To replicate earlier positive effects of a cognitive-behavioral prevention program of depressive symptoms and to test the hypothesis that the prevention program would be less effective in adolescents with comorbid anxiety and externalizing symptoms, a study was conducted involving 301 8th-grade students, randomly divided into an intervention group and a non-intervention control group. The randomized design included baseline, post-intervention, and 6-month follow-up. The prevention program included 10 sessions held in a regular school setting. …

Progesterone Receptors: Form And Function In Brain, Roberta Diaz Brinton, Richard F. Thompson, Michael R. Foy, Michel Baudry, Jun Ming Wang, Caleb E. Finch, Todd E. Morgan, Christian J. Pike, Wendy J. Mack, Frank Z. Stanczyk, Jon Nilsen

Psychological Science Faculty Works

Emerging data indicate that progesterone has multiple non-reproductive functions in the central nervous system to regulate cognition, mood, inflammation, mitochondrial function, neurogenesis and regeneration, myelination and recovery from traumatic brain injury. Progesterone-regulated neural responses are mediated by an array of progesterone receptors (PR) that include the classic nuclear PRA and PRB receptors and splice variants of each, the seven transmembrane domain 7TMPRβ and the membrane-associated 25-Dx PR (PGRMC1). These PRs induce classic regulation of gene expression while also transducing signaling cascades that originate at the cell membrane and ultimately activate transcription factors. Remarkably, PRs are broadly expressed throughout the brain …

Progesterone Regulation Of Synaptic Transmission And Plasticity In Rodent Hippocampus, Michael R. Foy, Garnik Akopian, Richard F. Thompson

Psychological Science Faculty Works

Ovarian hormones influence memory formation by eliciting changes in neural activity. The effects of various concentrations of progesterone (P4) on synaptic transmission and plasticity associated with long-term potentiation (LTP) and long-term depression (LTD) were studied using in vitro hippocampal slices. Extracellular studies show that the highest concentration of P4 tested (10⁻⁶ M) decreased the baseline synaptic transmission and magnitude of LTP, but did not affect LTD. Intracellular studies suggest the P4 effect to be mediated, at least in part, by GABAA activity. These results establish a general effect of P4 on synaptic transmission, multiple forms of synaptic plasticity, and …

Pigeons’ Memory For Time: Assessment Of The Role Of Subjective Shortening In The Duration Of Comparison Procedure, Patrick Van Rooyen

Theses and Dissertations (Comprehensive)

In Experiment 1, pigeons were trained with a 1-s baseline s-c delay in a duration comparison procedure to peck one key if a comparison duration (c) was 1-s shorter than a standard duration (s), and another key if c was 1-s longer than s. The duration pairs used prevented pigeons from relying on the absolute duration of c on some trials (comparison common) while on other trials they could rely on the absolute duration of c (comparison unique). Pigeons were then tested with equal duration pairs at extended s-c delays of 1, 2, 4, and …

The Cultural Dimension Of Emotional Intelligence And Its Clinical Implications, Koyeli Sengupta

Masters Theses

The purpose of this thesis was to examine the role that culture plays in emotionaJ intelligence, in people's ability to use emotions adaptively in their daily lives. Specifically, it presented existing cross-cultural research literature on emotional intelligence, with particular focus on the emotional competencies of Americans and Indians. The literature on cross-cultural psychology of emotions revealed cross-cultural similarities as well as differences in each phase of the emotion process. It supported the view that considerable universality existed with regards to perception of emotions in facial expressions, while the major sources of differences were detected in the processes ofregulation of emotion …

Field Of View Effects On Reflexive Motor Response In Flight Simulation, Javier Covelli

Electronic Theses and Dissertations

Virtual Reality (VR) and Augmented Reality (AR) Head Mounted Display (HMD) or Head Worn Display (HWD) technology represents low-cost, wide Field of Regard (FOR), deployable systems when compared to traditional simulation facilities. However, given current technological limitations, HWD flight simulator implementations provide a limited effective Field of View (eFOV) far narrower than the normal human 200[degrees] horizontal and 135[degrees] vertical FOV. Developing a HWD with such a wide FOV is expensive but can increase the aviator's visual stimulus, perception, sense of presence and overall training effectiveness. This research and experimentation test this proposition by manipulating the eFOV of experienced pilots …

Perception And Displays For Teleoperated Robots, Linda Upham Ellis

Electronic Theses and Dissertations

In remote or teleoperational tasks involving humans and robots, various aspects of the remote display system may greatly influence the individual's interactions with the teleoperated entity. This dissertation examined various configurations of display systems on several measures of operator performance, physiological states, and perceptions of the task. Display configurations included altering the camera placement (attached to the robot or placed overhead), screen orientation (horizontal or vertical), and screen size (small or large). Performance was measured in terms of specific task goals, accuracies, strategies, and completion times. Physiological state was assessed through physiological markers of arousal, specifically heart rate and skin …

Trait Arousability And Its Impact On Adaptive Multimedia Training, Sae Schatz

Electronic Theses and Dissertations

Today's best intelligent, adaptive, multimedia trainers have shown excellent performance; however, their results still fall far-short of what good human tutors can achieve. The overarching thesis of this paper is that future intelligent, adaptive systems will be improved by taking into account relevant, consistent, and meaningful individual differences. Specifically, responding to individual differences among trainees will (a) form more accurate individual baselines within a training system, and (b) better inform system responses (so that they interpret and respond to observable data more appropriately). One variable to consider is trait arousability, which describes individual differences in sensitivity to stimuli. Individuals' arousability …

Am I Too Fat To Be A Princess? Examining The Effects Of Popular Children's Media On Preschoolers' Body Image, Sharon Hayes

Electronic Theses and Dissertations

The current study investigated the effects of brief exposure to appearance-related media on female preschoolers' body image. Results indicated that exposure did not affect body dissatisfaction or engagement in appearance-related play behaviors. Surprisingly, participants' self-reported frequency of weight concerns decreased at posttest. In contrast to older populations, it is possible that young children may adopt the persona of attractive characters with whom they identify rather than comparing themselves to the characters. This level of identification temporarily may alleviate weight concerns. This is the first empirical study to provide support for previous findings that suggest media exposure does not affect body …

Gamma Hydroxybutyrate Use Among College Students: Application Of A Memory Model To Explore The Influence Of Outcome Expectancies, Pamela Brown

Electronic Theses and Dissertations

Gamma Hydroxybutyrate (GHB) was banned from the consumer market by the Food and Drug Administration in 1991. Despite the ban, use of GHB has continued to contribute to thousands of emergency department visits and numerous fatalities in recent years. Efforts to reduce the use of this drug have had limited impact, which may be the result of using traditional prevention strategies that focus exclusively on educating people about of negative consequences of substance use rather than addressing the factors that motivate use. In an effort to identify motivational factors that could be targeted in future prevention efforts, the present study …

Tactile Working Memory And Multimodal Loading, Peter Terrence

Electronic Theses and Dissertations

This work explored the role of spatial grouping, set size, and stimulus probe modality using a recall task for visual, auditory, and tactile information. The effects of different working memory (WM) loading task modalities were also examined. The Gestalt spatial organizing principle of grouping showed improvements in response times for visual and tactile stimulus probes with large set sizes and apparently allowed participants to effectively chunk the information. This research suggests that tactile information may use spatial characteristics typically associated with visual information, as well as sequential characteristics normally associated with verbal information. Based on these results, a reformulation of …

Investigating The Effects Of Tactile Stress On A Military Touniquet Application Task, Razia Nayeem

Electronic Theses and Dissertations

In combat, soldiers encounter stress from multiple sources including loss of sleep, extremely high levels of physical and psychological discomfort, extended periods of increased vigilance, and intense danger. Therefore, it is imperative to train such personnel on how to cope with these stressors. One way to do this is to include stressors in different forms of training to acclimate soldiers to the subsequent stress of combat. Due to their advantages, tactile trainers are being investigated increasingly for the use of training Army medics in this context. The present work examines how vibrating tactile sensors, or tactors, can be used as …

Gone In Sixty Milliseconds: Trademark Law And Cognitive Science, Rebecca Tushnet

Georgetown Law Faculty Publications and Other Works

Trademark dilution is a cause of action for interfering with the uniqueness of a trademark. For example, consumers would probably not think that "Kodak soap" was produced by the makers of Kodak cameras, but its presence in the market would diminish the uniqueness of the original Kodak mark. Trademark owners think dilution is harmful but have had difficulty explaining why. Many courts have therefore been reluctant to enforce dilution laws, even while legislatures have enacted more of them over the past half century. Courts and commentators have now begun to use psychological theories, drawing on associationist models of cognition, to …

Fifty Years Of Memory Of College Grades: Accuracy And Distortions, Harry P. Bahrick, Lynda K. Hall, Laura A. Da Costa

All Faculty and Staff Scholarship

One to 54 years after graduating, 276 alumni correctly recalled 3,025 of 3,967 college grades. Omission errors increased with the retention interval, and better students made fewer errors. Accuracy of recall increased with confidence in recall. Eighty-one percent of commission errors inflated the actual grade. Distortions occur soon after graduation, remain constant during the retention interval, and are greater for better students and for courses students enjoyed most. Confidence in recall is unrelated to distortion. Courses that were not freely recalled, but had to be cued, were recalled less accurately and with less distortion. The data support a supplementary theory …

The N400 Erp: Semantic Vs. Evaluative Incongruities, Jennifer Hilda Taylor

Open Access Theses & Dissertations

The objective of this research was to utilize both behavioral (response times) and psychophysiological measures (ERPs - N400 & Pre-response Positivity) to uncover the cognitive mechanism responsible for the evaluative priming effect (spreading activation vs. response competition) by controlling for semantic influences. This research project examined the evaluative incongruity effect by controlling for semantic influences in two separate studies. The first study kept semantic associations among word pairs completely random, while the second study controlled for semantic associations by either pairing words from the same semantic category (e.g., animal-animal) or from different semantic categories (e.g., animal-person). Participants completed an evaluative …

Molecular Characterization Of Dopamine Transporter Phosphorylation And Regulation, Balachandra Kumar Gorentla

Theses and Dissertations

The dopamine transporter (DAT) is a presynaptic membrane phosphoprotein that terminates dopaminergic synaptic transmission by clearing dopamine (DA) back into presynaptic neuron by a reuptake process. DAT is also a molecular target for psychostimulants such as cocaine, amphetamine (AMPH) and methamphetamine (METH) that increase DA synaptic levels either by blocking reuptake or by inducing DA efflux. DAT phosphorylation and transport down regulation are best demonstrated with the treatment of Protein kinase C (PKC) activators such as (phorbol 12-myristate 13-acetate) PMA. Serine(s) and threonine(s) are known to be involved in DAT phosphorylation.

Pretreatment with psychostimulant substrates such as AMPH and METH …

Effect Of Statute Changes On Admission Trends At A New Jersey State Psychiatric Hospital , Monica Malone

PCOM Psychology Dissertations

The impact of changes in New Jersey civil commitment laws on admission patterns at a New Jersey state psychiatric hospital was studied using an interrupted time series design. The target years were 1965, 1988, 1994, and 1998, years when significant changes in the commitment law took effect. The data studied were the total number of admissions per month. There were no significant changes in admission trends at any of the target dates. Possible reasons for these findings are discussed.

Trips Down Memory Lane: Recall Direction Affects The Subjective Distance Of Past Events, Kent C.H. Lam

Theses and Dissertations (Comprehensive)

The subjective temporal distance of a past event—how close or far away it feels—is influenced by numerous factors apart from actual time. The present studies extend research on subjective distance by exploring the experience of remembering autobiographical events as part of a stream of related events. It is proposed that a key determinant of subjective distance is the temporal direction in which events are recalled. Five experiments supported the hypothesis that people feel closer to a target event when they recall a stream of related events in a backward direction (i.e., a reverse-chronological order ending with the target event) rather …
