The Effects Of Reinforcement Magnitude On Functional Analysis Outcomes, Valerie Marie Volkert
The Effects Of Reinforcement Magnitude On Functional Analysis Outcomes, Valerie Marie Volkert
LSU Master's Theses
The functional analysis methodology developed by Iwata, Dorsey, Slifer, Bauman, and Richman (1982/1994) has been successfully used to identify the variables that maintain the problem behavior of individuals with developmental disabilities. However, in some cases, the results of functional analysis may be inconclusive. Altering parameters of reinforcement, such as the schedule, the quality, or magnitude of the reinforcer, may increase the likelihood of obtaining clear functional analysis results. Few studies have evaluated the effects of reinforcement magnitude on problem behavior even though basic findings indicate that this parameter may alter functional analysis outcomes. In fact, reinforcement magnitude has varied widely …
A Stage Targeted Physical Activity Intervention Among A Predominantly African American Low Income Medical Population, Dorothy Whitehead
A Stage Targeted Physical Activity Intervention Among A Predominantly African American Low Income Medical Population, Dorothy Whitehead
LSU Master's Theses
Despite the numerous health benefits, there is a high prevalence of physical inactivity and associated chronic diseases in the U.S., particularly among low income African Americans. Past studies indicate that mailed, stage-matched physical activity promotion materials are effective, low cost, and show potential for reaching hard to reach groups. However, this has not been examined in a low-income African American population. The current study utilized a low-cost, mailed intervention to promote physical activity among a low income African American primary care population (N=207). The sample was predominantly female (82.6%), African American (69.1%), and overweight (81.3%). At baseline, all participants completed …
Difference In Sleep Disturbances Among Severely And Profoundly Retarded Adults With High Risk Behaviors, Carrie Jo Malone
Difference In Sleep Disturbances Among Severely And Profoundly Retarded Adults With High Risk Behaviors, Carrie Jo Malone
LSU Master's Theses
Individuals with intellectual disabilities have been linked to higher incidences of a variety of mental illnesses when compared to the general population (Rutter, Tizard, Yule, Graham, & Whitmore, 1976; and Borthwick-Duffy, 1994). Because of the symptoms associated with mental retardation; such as limited social skills, delayed or minimal communication skills, and maladaptive behaviors, mental illness can be difficult to assess when combined with an intellectual disability (Sovner, 1986). Currently there is no available mechanism for diagnosing sleep disorders in adults with severe and profound mental retardation. The purpose of the first study is to provide validation of the Diagnostic Assessment …
Are We Honestly Studying Malingering?: A Profile And Comparison Of Simulated Suspected Malingerers, Adrianne M. Brennan
Are We Honestly Studying Malingering?: A Profile And Comparison Of Simulated Suspected Malingerers, Adrianne M. Brennan
LSU Master's Theses
Malingering research typically uses analog simulation designs or the differential prevalence design among "real" patients. Both have been criticized for methodological limitations in external and internal validity, respectively. Samples of simulated malingerers were compared to suspected malingerers to examine generalizability of analog findings. Overall results support the use of simulation designs. Furthermore, it was demonstrated that stringent selection of suspected malingerers maintains internal validity of the differential prevalence design. A second focus, to determine if demographic matching of simulated malingerers is necessary, showed that matching on age and race is not necessary.
The Effects Of Internal And External Context Reinstatement On Source Memory, Jeffrey Joseph Starns
The Effects Of Internal And External Context Reinstatement On Source Memory, Jeffrey Joseph Starns
LSU Master's Theses
Memory for attended aspects of an encoded event (item memory) is facilitated when features of the encoding context are reinstated at test, indicating that item and context features are bound together in memory traces (Smith, 1979). The present study investigated whether reinstated contextual features similarly enhance memory for other contextual details of an event (source memory). Participants studied words that appeared on either the top or bottom of the computer screen in either a large or small font size. Following the study phase, participants completed a recognition/source test in which they had to indicate the location in which they studied …
Commitment To Displaying Positive Emotions At Work: An Examination Of Individual And Situational Antecedents, Meredith H. Croyle
Commitment To Displaying Positive Emotions At Work: An Examination Of Individual And Situational Antecedents, Meredith H. Croyle
LSU Master's Theses
Studies show that employee emotional displays impact customer behaviors and attitudes (Grandey, Fisk, Mattila, & Sideman, 2002; Pugh, 2001; Tsai, 2001). However, the factors influencing employees' emotional displays have not received much attention. More specifically, research suggests a need to more fully understand the motivational processes underlying employees' emotional displays, particularly in customer service where positive emotional displays are related to customer behaviors and sales performance (Brown & Sulzer-Azaroff, 1994; Diefendorff & Gosserand, in press; Grandey, Fisk, Matilla, & Sideman, 2002; Pugh, 2001; Tsai, 2001). To this end, this investigation examined an expectancy theory model of commitment to positive emotional …
Examining The Relationships Between Motivational Traits And Counterproductive Work Behaviors, Kajal Rushikesh Mehta
Examining The Relationships Between Motivational Traits And Counterproductive Work Behaviors, Kajal Rushikesh Mehta
LSU Master's Theses
This study examined the relationships between motivational traits and counterproductive work behaviors. Little evidence exists supporting a link between individual differences and counterproductive work behaviors in previous literature. This study tested for a link between individual differences in motivation and workplace deviance by using broad operationalizations of both constructs. In addition, the investigation controlled for the effects of situational factors on counterproductive work behaviors providing a stronger test of the role of dispositional motivation. In general, this study set out to show that both approach and avoidance motivation tendencies are related to counterproductive work behaviors, as well as organizational citizenship …
Attribution Processes In Mother-Adolescent Conflict, Ann Elisabeth Wingate
Attribution Processes In Mother-Adolescent Conflict, Ann Elisabeth Wingate
LSU Master's Theses
The present study aimed to determine whether negative mother and adolescent attributions about one another are associated with increased conflict levels in a heterogeneous sample, examine the possible differential predictive power of certain negative attribution types for different groups within the sample, determine whether level of negative attribution, SES, or daily stress level are significant predictors of conflict, and examine the potential mediating role of negative attributions in the relationship between SES and conflict level, as well as the relationship between and daily stress and conflict level. One hundred forty-five mother-adolescent dyads from various racial and SES backgrounds of a …
A Cross-Sectional Study Comparing The Psychosocial Correlates For Overconcern With Body Size And Shape In Men And Women, Amy Elaine Rzeznikiewicz
A Cross-Sectional Study Comparing The Psychosocial Correlates For Overconcern With Body Size And Shape In Men And Women, Amy Elaine Rzeznikiewicz
LSU Master's Theses
The purposes of this cross-sectional study were two-fold. The primary aim of this study was to test whether the Muscle Appearance Satisfaction Scale (MASS), a recently developed, reliable, and valid measure of muscle dysmorphia symptoms, measures a parallel phenomenon in men that the Body Shape Questionnaire (BSQ) does in women, i.e., overconcern with body size and shape. To test this aim, psychosocial correlates for overconcern with body size and shape in women were tested to be the same psychosocial correlates for a measure of muscle dysmorphia in men. The psychosocial variables included in this model were body dissatisfaction, negative affect, …
State-Specific Effects Of Withdrawal In Smokers, Carla J. Rash
State-Specific Effects Of Withdrawal In Smokers, Carla J. Rash
LSU Master's Theses
Comparisons of responses to a free-recall task were made in withdrawal and non-withdrawal states of 41 smokers. A 2 x 2 design was used to investigate state-specific learning effects in smokers during nicotine withdrawal using a list of 20 common words. Nicotine withdrawal was defined as a minimum of 12 hours abstinence from smoking. Physiological measures of heart rate and blood pressure were examined for drug-compensatory responses. No significant decreases in physiological responding were found. Additionally, no interaction was found between reported urge and withdrawal. The primary hypothesis regarding state-specific effects on recall was not supported. These findings are to …
Reliability And Concordance Of The Childhood Autism Rating Scale And Dsm-Iv In Adults With Severe And Profound Mental Retardation, Noha Farrah Minshawi
Reliability And Concordance Of The Childhood Autism Rating Scale And Dsm-Iv In Adults With Severe And Profound Mental Retardation, Noha Farrah Minshawi
LSU Master's Theses
Researchers and clinicians have long treated autism as though it were a disorder that only affected children. As a result, little literature is available on the diagnosis, assessment, and treatment of adults with autism. One of the first issues to address in this population is diagnosis. While several rating scales and diagnostic systems exist for surveying autistic behavior in children, researchers have not demonstrated the reliability of these scales for adults. The present study focused on two commonly used instruments, the Childhood Autism Rating Scale (CARS) and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). In the …
The Loss Of Parental Contact: Prevalence And Consequences Experienced Past And Present, Robert A. Wright
The Loss Of Parental Contact: Prevalence And Consequences Experienced Past And Present, Robert A. Wright
LSU Master's Theses
The loss of a parent is a difficult and potentially very upsetting event for a child. Along with the loss of parental contact and the emotional toll, the death, divorce, abandonment, or imprisonment of a parent can also disrupt many on-going facets of a child’s life, including school, social relationships, athletics, and other interests. Despite the potentially devastating nature of parental loss, relatively little is known about the frequency of parental loss or the consequences of this loss. This study examined the prevalence of parental loss and the consequences experienced in both the short and long term. Two separate interview …
Heavy Smokers Choose Large, Immediate Rewards With Large Penalties On A Simulated Task Of Gambling, Michael Shawn Businelle
Heavy Smokers Choose Large, Immediate Rewards With Large Penalties On A Simulated Task Of Gambling, Michael Shawn Businelle
LSU Master's Theses
The Gambling Task is a complex neuropsychological test (in the form of a card game) that examines the ability of individuals to assess potential immediate gains over long-term losses. Gambling Task performance has been examined in previous studies with individuals who are dependent on alcohol, cocaine, heroin, and amphetamine. These studies have shown that those who are dependent on the aforementioned substances perform more poorly on the Gambling Task than controls. Specifically, in relation to controls, drug/alcohol dependent individuals show impairment by tending to pick more cards that have large immediate gains and very large delayed punishers. The delayed punisher …
An Evaluation Of Distributed Practice Using Constant Time Delay In The Acquisition Of Sight Words With Children, Kashunda Lynn Williams
An Evaluation Of Distributed Practice Using Constant Time Delay In The Acquisition Of Sight Words With Children, Kashunda Lynn Williams
LSU Master's Theses
Although, distributed practice has been demonstrated to be superior to massed practice for learning, studies examining the degree of distribution needed to obtain this effect remain lacking. This study extends prior research by (1) determining if there is a difference in distributed practice schedules, when the total time to practice remains constant, (2) determining which schedule produces the superior amount of learning, and (3) determining which schedule produces superior retention of learned materials across time. Study participants were general education elementary school students referred for reading assistance. The constant time delay procedure was used to teach the participants sight words. …
The Impact Of Parents' Implementation Of A Structured Parent Reading Program On Their Children's Reading Fluency, Jennifer Luella Resetar
The Impact Of Parents' Implementation Of A Structured Parent Reading Program On Their Children's Reading Fluency, Jennifer Luella Resetar
LSU Master's Theses
This study investigated the effectiveness of a method of parent training and parent reading tutoring that built on past research. Parents of five first grade children, who were reading below grade level, participated. Parents were trained to implement a three-week tutoring procedure that included modeling, practice, phonics, fluency, accuracy, comprehension, and reinforcement components. According to permanent product examination, parent intervention implementation never fell below 82% integrity. A multiple baseline across participants design was used to analyze results. According to visual analysis, four of the five children showed significant gains in words correct per minute on tutored reading passages. There was …
Evaluation Of Computerized Reading Intervention, Jennifer Lynne Koenig
Evaluation Of Computerized Reading Intervention, Jennifer Lynne Koenig
LSU Master's Theses
The purpose of this study was to evaluate the effectiveness of a computer-based reading intervention with eight elementary school children. This program, called the Reading Center, utilizes repeated reading, listening passage preview, word drills, and comprehension questions. A multiple baseline design was used to evaluate the intervention effects on oral reading fluency. Results indicated growth in all eight children, with increases between 8.7 and 20 words per week for intervention passages. The implications of the results for the use of computer-delivered interventions are discussed.
Relative Efficacy Of School-Home Notes With And Without Response Cost In Impoverished Elementary School Students With Attention-Deficit/Hyperactivity Disorder, Andrea Nichole Jurbergs
Relative Efficacy Of School-Home Notes With And Without Response Cost In Impoverished Elementary School Students With Attention-Deficit/Hyperactivity Disorder, Andrea Nichole Jurbergs
LSU Master's Theses
Daily report cards and punishment have proven to be effective methods of classroom behavior management. However, treatment effectiveness studies have not been designed to adequately compare the effects of rewarding and punishing consequences on behavior through a school-home note. The study of school-home note treatment effectiveness has focused on middle-class students with behavior problems; both ADHD and disadvantaged populations have been underresearched. Using a reversal, alternating treatments design, the present study will examine the effectiveness of a response-cost system added to school-home notes for increasing classwork completion and appropriate classroom behavior in several disadvantaged elementary school children with ADHD.
Monitoring In Event-Based Prospective Memory Tasks, Dale Watkins Cockman
Monitoring In Event-Based Prospective Memory Tasks, Dale Watkins Cockman
LSU Master's Theses
Event based prospective memory (PM) refers to remembering to perform a particular action upon the presentation of a particular cue in the environment. Until recently, most models of event-based PM performance have suggested that the realization of the target event occurs automatically. The DARC model (Smith, 2000) is among the first to suggest that monitoring is required to notice the target event, in the form of a consistent, non-strategic dedication of resources. The predictions of the DARC model are contrasted with those of Einstein & McDaniel (Noticing + Search, 1996), Goschke & Kuhl (1996), Ellis (1996). The pilot study and …
Factors Influencing The Effects Of Realistic Job Previews On Applicant Judgments Of Organizational Attractiveness, Natalie Trask Bourgeois
Factors Influencing The Effects Of Realistic Job Previews On Applicant Judgments Of Organizational Attractiveness, Natalie Trask Bourgeois
LSU Master's Theses
Realistic job previews (RJPs) involve the presentation of both positive and negative job attributes to job applicants. Although several researchers have studied effects of RJPs on satisfaction, turnover, and performance, comparatively less research has focused on the effects of RJPs on attraction. This study extends previous RJP research by sampling both students who are education majors and currently employed teachers. It compared their ratings of attraction to organizations represented by an RJP or a traditional job preview (TJP). In addition, both teachers and education students completed a measure of negative affectivity (NA). Contrary to expectations, results of this study showed …
Toward Validation Of The Sports Behavior Checklist: A Comparison Of Attention-Deficit/Hyperactivity Disorder And Control Group Children In A Sports Environment, Aaron Clendenin
LSU Master's Theses
Data from participants (N = 124) was entered into a principal components analysis to test the factor structure of the Sports Behavior Checklist ([SBC] Johnson & Rosen, 2000). The subscales of the SBC were correlated with relevant subscales of the Conners'- Revised Parent Form ( Conners, 1997) and Social Skills Rating System (Gresham & Elliott, 1990). Both of these analyses were conducted to determine the construct validity of the instrument. Additionally, a subsample (N = 92) of low socioeconomic status individuals was used to compare groups of Attention-Deficit/Hyperactivity Disorder (n = 49) and non-clinical (n = 43) children on the …
Goal Orientation And Feedback Sign As Predictors Of Changes In Motivation And Performance, Erin Michele Richard
Goal Orientation And Feedback Sign As Predictors Of Changes In Motivation And Performance, Erin Michele Richard
LSU Master's Theses
This study examined the dimensions of goal orientation as moderators of the effects of feedback sign on changes in self-efficacy, effort, and performance over time. In general, the effect of feedback sign on changes in self-efficacy, effort, and performance was hypothesized to be strong for individuals high on performance goal orientation (PGO) and weak for individuals high on learning goal orientation (LGO). Participants completed several performance blocks of an implicit learning task that required individuals to control the temperature of a simulated chemical reactor. Participants were given manipulated normative feedback after each trial. Self-efficacy, effort, and performance were assessed at …
Major And Minor Life Events As Predictors Of Medical Utilization, Gareth R. Dutton
Major And Minor Life Events As Predictors Of Medical Utilization, Gareth R. Dutton
LSU Master's Theses
Research suggests stressful life events can negatively influence physical and mental health in a number of ways. While previous research indicates both major and minor life events contribute unique variance to the prediction of physical and mental symptoms, little research has examined the relationships of both major and minor life events with medical utilization. The current study included a predominantly African American, low-income sample of adults (N = 207) attending two primary care outpatient clinics and assessed their experience of both major and minor life events over the course of one year. Medical utilization data were collected over a subsequent …
The Relationship Of Feeding Problems With The Use Of Antiepileptic Medication Among Persons With Severe And Profound Mental Retardation, Rinita B. Laud
The Relationship Of Feeding Problems With The Use Of Antiepileptic Medication Among Persons With Severe And Profound Mental Retardation, Rinita B. Laud
LSU Master's Theses
Epilepsy and/or seizure activity are frequently occurring phenomena and a significant co-morbid condition for persons with severe to profound intellectual disability (Burke, McKee, Pathak, Donahue, Parasuraman & Baltenhorst, 1999). The majority of seizure activity leads to deficits across a number of social, physical,occupational, and personal variables, and if left untreated, may lead to death in these individuals. The treatment of this condition frequently utilizes anti-epileptic medication, but these medications are often associated with a variety of side effects such as dental complications and disturbed gait. Previous researchers have suggested that these side effects may be manifested in forms of maladaptive …
Control Of Food Intake And Body Weight Following Smoking Cessation In Premenopausal Women, Jamie Lynn Neal
Control Of Food Intake And Body Weight Following Smoking Cessation In Premenopausal Women, Jamie Lynn Neal
LSU Master's Theses
Women experience more weight gain than men postcessation and are more aware of nicotine’s weight suppressing effects than men. Postcessation weight gain in women can be largely accounted for by significant increases in high fat foods from pre- to postcessation. Overeating found in the luteal phase, further compounds the increased caloric intake found postcessation. Few studies have evaluated the long-term effects of smoking cessation on macronutrient content and weight gain; and most have relied on self-report data. This study used the Macronutrient Self-Selection Paradigm (MSSP) and Food Preference Questionnaire (FPQ) to assess food intake in 17 women in the luteal …
Useful Field Of View Of An Indicator Of Accident Risk: Results From A College Sample, Jeffrey James Schneider
Useful Field Of View Of An Indicator Of Accident Risk: Results From A College Sample, Jeffrey James Schneider
LSU Master's Theses
Driving is an important part of daily life in our society. Neurocognitive deficits acquired from a head injury can affect driving ability. Determining when it is safe for a person recovering from a head injury to return to the road can often be difficult. With the risk involved in an on-the-road driving evaluation, effective measures are needed to determine when patients are ready to be evaluated. Some neuropsychological measures have shown promise in this area. The Useful Field of View (UFOV) is one test that has been used successfully with older drivers to predict accident risk. Research has also been …
The Effects Of Implicit, Explicit, And Synergistic Training On Learning An Artificial Grammar, Thomas James Domangue
The Effects Of Implicit, Explicit, And Synergistic Training On Learning An Artificial Grammar, Thomas James Domangue
LSU Master's Theses
Participants were trained to generate exemplars of an artificial grammar by bubbling-in letters from exemplars (implicit training), observing a diagram of the grammar then reproducing it (explicit training), or tracing the path of exemplars through a diagram of the grammar (synergistic training). Performance was measured using a cued-generate task. It provided a template for an exemplar with two letters filled in. Participants attempted to generate exemplars that fit the template. The computer corrected the exemplar when it matched at least 70% of the letters in a valid string. Results showed that both explicit and synergistic training led to generation of …
Who's Not Dieting In America And Who Should Be? Results From The 1994-1996 Diet And Health Knowledge Survey (Dhks 1994-1996), Emily York-Crowe
Who's Not Dieting In America And Who Should Be? Results From The 1994-1996 Diet And Health Knowledge Survey (Dhks 1994-1996), Emily York-Crowe
LSU Master's Theses
The rising rates of obesity and overweight are contributing to higher costs for the individual and the nation, both medically and financially. There is a greater need for education and other preventive measures, but in order to tailor such programs effectively to the individuals most in need, it is important to examine the current trends, knowledge, and practices of adults in the United States. Previous research has examined the prevalence rates and practices of specific populations and individuals in limited geographical locations but, due to obvious constraints, few nationally representative samples have been examined. This study analyzed the results of …
Spaced-Retrieval Effects On Name-Face Recognition In Older Adults With Probable Alzheimer's Disease, Karri Sikes Hawley
Spaced-Retrieval Effects On Name-Face Recognition In Older Adults With Probable Alzheimer's Disease, Karri Sikes Hawley
LSU Master's Theses
Six older adults with probable Alzheimer’s disease (AD) were trained to recall a name-face association using the spaced-retrieval method. We administered six training sessions over a two-week period. On each trial, participants selected a target photograph and stated the target name, from eight other photographs, at increasingly longer retention intervals. Results yielded a positive effect of spaced-retrieval training for name-face recognition. All participants were able to select the target photograph and state the target’s name for longer periods of time within and across training sessions. A live person transfer task was administered to determine whether the name-face association, trained by …
In Defense Of Malingering: A Cautionary Note, Dennis R. Dixon
In Defense Of Malingering: A Cautionary Note, Dennis R. Dixon
LSU Master's Theses
The simulation and exaggeration of job related injury symptoms is a significant problem in the Workers' Compensation system. The result of simulation and exaggeration is the inappropriate allotment of financial resources to workers whose actual injuries do not warrant such compensation. Psychology as a field has done much research in the past years to address the detection of malingering. Most of that focus has viewed malingering behavior as a personal choice, as well as being indicative of a character flaw. However, the degree to which external factors such as work conditions increase the likelihood of an individual malingering has received …
