Challenging Behaviors In Children With Comorbid Autism Spectrum Disorder And Attention-Deficit/Hyperactivity Disorder, Katherine Margaret Macmillan
Challenging Behaviors In Children With Comorbid Autism Spectrum Disorder And Attention-Deficit/Hyperactivity Disorder, Katherine Margaret Macmillan
LSU Master's Theses
Challenging behaviors, such as aggression, destruction, self-injurious behaviors, or stereotypic movements, affect the majority of individuals with Autism Spectrum Disorder. One factor that is known to influence the frequency at which challenging behaviors occur is the presence of a comorbid disorder. Attention-deficit/hyperactivity disorder (ADHD) is thought to be one such disorder. This study aimed to compare the prevalence rates of challenging behaviors, according to the Autism Spectrum Disorder-Behavior Problems, Child Version (ASD-BPC), in children ages 6-16 with parent reported symptoms of ASD, ADHD, comorbid ASD/ADHD, and no diagnosis. Differences existing overall were examined as well as differences on the ASD-BPC’s …
Adult Adhd In Dsm-Iv-Tr And Dsm-5: Impact Of Increased Age-Of-Onset On Prevalence, Morgan Ashwill Grinnell
Adult Adhd In Dsm-Iv-Tr And Dsm-5: Impact Of Increased Age-Of-Onset On Prevalence, Morgan Ashwill Grinnell
LSU Master's Theses
Attention-Deficit/Hyperactivity Disorder (ADHD) is a prevalent disorder estimated to affect 3%-7% of children and about 4% of the adult population. In adults, ADHD is associated with lower academic achievement, more interpersonal conflicts and a bevy of other negative outcomes. Research on the assessment and treatment of ADHD in adults has considerably lagged behind research conducted with children. Existing research has been influential in the American Psychiatric Association’s (APA) decision to update the Diagnostic and Statistical Manual of Mental Disorders (DSM) definition of ADHD to include more developmentally expansive criteria. Modifications to the fifth edition of the manual (DSM-5) included an …
Social Support As A Protective Factor For Bullied Children And Adolescents, Seandra Jean Cosgrove
Social Support As A Protective Factor For Bullied Children And Adolescents, Seandra Jean Cosgrove
LSU Master's Theses
The impact of bullying on children’s self-esteem, confidence, and social acceptance has become increasingly recognized. Considerable research has evaluated the deleterious effects of bullying and protective and risk factors as a result of victimization. Past research has shown social support to be a protective factor for children and adolescents who have been subjected to negative experiences, such as experiencing traumatic events (Vigna, Hernandez, Paasch, Gordon, & Kelley, 2009). However, research has not evaluated whether social support buffers the impact of bullying on children and adolescents. The current study investigated perceived social support and its role as a protective factor against …
The Impact Of Menstrual Cycle Phase On Smoking Cessation-Related Variables, Mackenzie Rae Peltier
The Impact Of Menstrual Cycle Phase On Smoking Cessation-Related Variables, Mackenzie Rae Peltier
LSU Master's Theses
Tobacco use remains the leading cause of preventable disease and death in the United States. Despite increased research and improved treatment modalities, rates of lapse and relapse remain high. Women in particular experience poorer smoking cessation outcomes (including more relapse), presumably due to unique considerations such as the hormonal milieu. Despite some conflicting results, researchers have speculated that timing cessation attempts to coincide with the luteal phase of the menstrual cycle, where levels of neuroprotective progesterone are at their peak, may decrease nicotine withdrawal and increase cessation success. Timing treatment onset with the luteal phase may positively impact smoking variables …
Recalled Bullying: Development Of A Measure To Identify Childhood Victims And Perpetrators By Adults, Melissa Munson
Recalled Bullying: Development Of A Measure To Identify Childhood Victims And Perpetrators By Adults, Melissa Munson
LSU Doctoral Dissertations
The purpose of the study was to develop a psychometrically sound measure of recalled childhood bullying by adults who were either victims or perpetrators of this behavior. In order to accomplish this, a measure of childhood bullying, the Peer Interactions in Primary School (PIPS) Questionnaire, was modified into a retrospective measure in order to quantify recollections of childhood bullying by adults. Specifically, the modified PIPS (PIPS-R) was created to identify adults who identified themselves as bullies, victims, or bully-victims during their childhood or who do not recall having been a bully or a victim. Eight hundred and twelve undergraduate college …
Inattentional Blindness And Auditory Attention: Effects Of Cognitive Load On Visual Awareness, Dillon James Cornett
Inattentional Blindness And Auditory Attention: Effects Of Cognitive Load On Visual Awareness, Dillon James Cornett
LSU Master's Theses
The current study investigated the effects of cognitive load, in the presence or absence of distractors, during a dynamic inattentional blindness (IB) task on IB rate. IB is a phenomenon where one fails to notice an unexpected object (UEO) or event (UEE) that is in full view while attention is occupied. In the present study, the presence of distractors was manipulated (present/absent) to investigate the effects of selective attention in inattentional blindness when inhibition of distractors is required or not required. Undergraduates at Louisiana State University completed a visual task while listening to music embedded with sine wave tones (low …
The Role Of Recursive Remindings On Memory Updating Of Emotional Stimuli, Tanya Karam
The Role Of Recursive Remindings On Memory Updating Of Emotional Stimuli, Tanya Karam
LSU Doctoral Dissertations
It has been argued that emotional memories are harder to update than neutral memories (Novak & Mather, 2009; Sakaki, Niki, & Mather, 2012) and that the cause is that emotional memories are subject to greater levels of proactive interference. This explanation was questioned in this paper and another explanation – the recursive reminding hypothesis (Hintzman, 2004) was considered. This hypothesis was used to explain the previous findings by suggesting that the remindings embedded in emotional memory representations are stronger than neutral remindings (as supported by a preliminary experiment) and therefore attract attention internally during re-presentation, resulting in less attention toward …
A Longitudinal Model Of Posttraumatic Stress And Posttraumatic Growth In Adults Affected By Hurricane Katrina, Mark Allen Schexnaildre
A Longitudinal Model Of Posttraumatic Stress And Posttraumatic Growth In Adults Affected By Hurricane Katrina, Mark Allen Schexnaildre
LSU Doctoral Dissertations
Numerous studies have documented the negative psychological outcomes in individuals who experienced Hurricane Katrina. However, little is known about the long-term adjustment of hurricane-exposed individuals, especially with regard to positive outcomes, in the years after the storm. Specifically, few studies have measured posttraumatic growth (PTG), which refers to positive psychological change achieved by individuals who struggled with a traumatic experience. In their model of PTG, Tedeschi and Calhoun theorize that a certain level of trauma-related psychological distress and disruption is necessary for PTG to develop. The current study attempted to test the PTG model with a longitudinal path analysis of …
Do Tight Deadlines And Dirty Diapers Fuel Or Fizzle The Next Big Thing? The Differential Effect Of Work And Non-Work Stressors On Employee Creativity, Rachel Trout
LSU Doctoral Dissertations
As our society has transitioned from an economy built on production to one built on knowledge, employee creativity has become necessary for organizations seeking to gain and maintain profits. Therefore, the focus of this dissertation was to investigate how an employee’s social environment, specifically stressors from their work and non-work roles, impacts their ability to generate new ideas at work. Two independent studies were conducted. Within Study 1, the challenge-hindrance framework was integrated with the componential model of creativity (Amabile, 1983) to determine how individual factors interacted with work and non-work stressors. Although main effects were present, moderation was not …
Longitudinal Predictors Of School Problems In Youth Affected By Hurricane Katrina, Julia Elizabeth Thompson
Longitudinal Predictors Of School Problems In Youth Affected By Hurricane Katrina, Julia Elizabeth Thompson
LSU Doctoral Dissertations
In the wake of Hurricane Katrina, youth faced significant disruption to their lives due to the storm damage and, for many, long-term evacuation. One domain of functioning that faced significant threat because of this disruption was student engagement. The purpose of this study was to examine predictors of student engagement, as measured by the BASC-2-SRP School Problems scale, in youth affected by the Hurricane Katrina over four time points (3-7 months, 13-17 months, 19-22 months and 25-27 months post-Katrina). Participants included 426 youths living in New Orleans and the surrounding parishes at the time Hurricane Katrina made land-fall. Examined predictors …
Improving Routines : Self-Monitoring By Adolescents Diagnosed With Attention-Deficit/Hyperactivity Disorder, Meghan Ann Geary
Improving Routines : Self-Monitoring By Adolescents Diagnosed With Attention-Deficit/Hyperactivity Disorder, Meghan Ann Geary
LSU Doctoral Dissertations
Attention-Deficit/Hyperactivity Disorder (ADHD), though commonly diagnosed in childhood, continues to present with problematic symptoms through adolescence and adulthood (Barkley, Fischer, Edelbrock, & Smallish, 1990; Young & Amarasinghe, 2010). Despite the number of adolescents suffering from ADHD and the detrimental effects the symptoms can have on their lives, there is a paucity of research in interventions tailored to this population (Young & Amarasinghe, 2010). Additionally, an even smaller portion of this research addresses daily routines for adolescents, despite findings that maintaining routines are often very difficult for adolescents with ADHD (Bloomquist, 2005; Coghill et al., 2008; Pfiffner et al. 2007; Robin, …
Influencing The Confirmation Bias On A Matchmaker Task Through Manipulation Of The Feeling Of Rightness, Patrick Clinton Ledet
Influencing The Confirmation Bias On A Matchmaker Task Through Manipulation Of The Feeling Of Rightness, Patrick Clinton Ledet
LSU Doctoral Dissertations
The confirmation bias occurs when an individual ignores potentially disconfirming evidence and gives greater attention to apparent confirming evidence. The confirmation bias is theorized to result from rapid, automatic and unconscious processing. Such processing generates decisions that are considered to be “good enough” to meet the demands of a situation. Although such judgments are guided by unconscious processing, the individual may have conscious awareness of the generated hypothesis while still failing to systematically consider important information. Previous attempts to counter the confirmation bias have focused on directly instructing individuals to use systematic decision making. This method has had some success …
Social Connectedness Deficits In College Students With Schizotypy, Laura Brown
Social Connectedness Deficits In College Students With Schizotypy, Laura Brown
LSU Doctoral Dissertations
Schizophrenia is a devastating disorder characterized by a variety of bizarre behaviors as well as deficits in neurocognition, social cognition, and functioning. This study focuses on individuals with schizotypy—those with the purported genetic liability for schizophrenia that do not display the full disorder. Prior research has identified potential risk factors for schizophrenia by studying this population, including deficits in social cognition. Studies of social cognition in individuals with schizotypy, however, have yielded inconsistent findings that have failed to fully explain the range of functional deficits seen in these individuals. Social connectedness, in contrast, may be a more useful risk factor …
The Baby And Infant Screen For Children With Autism Traits: Age-Based Scoring Procedures, Max Horovitz
The Baby And Infant Screen For Children With Autism Traits: Age-Based Scoring Procedures, Max Horovitz
LSU Doctoral Dissertations
As increasing interest and emphasis has been placed on early intervention for children with Autism Spectrum Disorders (ASD), the need for reliable and valid early assessment techniques has grown significantly. The Baby and Infant Screen for Children with aUtIsm Traits (BISCUIT) is a three-part battery designed to comprehensively assess for ASD in infants and toddlers aged 17 to 37 months. While studies of the measure’s psychometric properties have been promising, the measure’s scoring procedures do not take the child’s age into account. Given the significant amount of development that occurs in the first three years of life, the current paper …
Reciprocal Peer Mentoring : Increasing The Prosocial Behavior Of Socially Neglected Students, Tai A. Collins
Reciprocal Peer Mentoring : Increasing The Prosocial Behavior Of Socially Neglected Students, Tai A. Collins
LSU Doctoral Dissertations
Two studies investigated the effectiveness of the Reciprocal Peer Mentoring intervention in improving the prosocial behavior of socially neglected elementary school students as measured by a Direct Behavior Rating filled out by their teachers. Reciprocal Peer Mentoring uses the methodological framework of the Check-In/Check-Out intervention (e.g. Hawken & Horner, 2003), but expands on it by using peers as mentors, adding a reciprocity component, focusing on prosocial behavior, and targeting socially neglected students. In Study 1, the effectiveness of Nonreciprocal Peer Mentoring was examined, as popular peers served as mentors for neglected peers. In Study 2, neglected or rejected students mentored …
The Effects Of Parent Factors On Children's Separation Anxiety, Anna Catherine May
The Effects Of Parent Factors On Children's Separation Anxiety, Anna Catherine May
LSU Doctoral Dissertations
Parental anxiety is a well-known factor that contributes to the development of anxiety in children. However, little is known about how specific parental factors influence the development and trajectory of childhood anxiety. There is also a paucity of research on separation anxiety disorder specifically. Complicating matters, children who suffer from clinically significant separation anxiety tend to be younger and thus it is harder to obtain accurate information from this age group. The purpose of the present study was to determine the mechanism through which parental factors such as somatization, anxiety sensitivity, and separation anxious behaviors might influence the development of …
What You Attend To Is What You Remember : Investigating The Unit Of Representation In Visual Working Memory, Amanda Elaine Van Lamsweerde
What You Attend To Is What You Remember : Investigating The Unit Of Representation In Visual Working Memory, Amanda Elaine Van Lamsweerde
LSU Doctoral Dissertations
The unit of representation in visual working memory (VWM) is a matter of some debate. The object benefit occurs when more features are remembered when they are combined into fewer objects. This has been used to support the perspective that objects are the unit of representation in VWM. However, the object benefit occurs only for two features from different dimensions (e.g., a blue circle: color and shape) but not two features from the same dimension (e.g., a red-and-blue bi-colored square: two colors). This suggests that both objects and features may be important in determining VWM capacity. The purpose of this …
Organization Benefits - The Panacea For All That Ails You? A Dyadic, Dual-Earner Investigation Of Organization-Offered Benefits And Their Effect On Individuals And Their Partners, Suzanne Marie Booth-Ledoux
Organization Benefits - The Panacea For All That Ails You? A Dyadic, Dual-Earner Investigation Of Organization-Offered Benefits And Their Effect On Individuals And Their Partners, Suzanne Marie Booth-Ledoux
LSU Doctoral Dissertations
In an effort to attract and retain top talent, organizations often offer and implement various organization benefits. The focus of this dissertation is on the outcomes of those offered organization benefits on employees and their partners. Three types of organization benefits were assessed: family-friendly benefits, financial and compensation benefits, and health care and wellness benefits. Additionally, the connection between the offering of these benefits with family-supportive organization perceptions was also examined. Family-supportive organization perceptions was shown to directly and indirectly link to individual-level outcomes including work-to-family conflict and psychological wellbeing. Moreover, because individuals do not exist in a vacuum (i.e., …
An Examination Of Induced Anxiety And Its Interaction With Trait Anxiety On Executive Functioning Tasks, Joseph Harris
An Examination Of Induced Anxiety And Its Interaction With Trait Anxiety On Executive Functioning Tasks, Joseph Harris
LSU Master's Theses
Anxiety is a common human experience which has been shown to have detrimental effects on cognitive abilities, particularly the executive abilities of inhibition, shifting and updating. Previous studies in this area have been highly specific in their focus, leaving gaps in the literature. As a result, the general nature of anxiety’s effect on executive functioning has yet to be fully defined. The current study attempted to establish such a definition by exploring the effects of state anxiety and trait anxiety on each of the executive functions, both in terms of task performance and efficiency. In addition, because working memory has …
Evaluating The Effectiveness Of A Classwide Social Skills Intervention With Preschoolers And Kindergarteners, Haley E. York
Evaluating The Effectiveness Of A Classwide Social Skills Intervention With Preschoolers And Kindergarteners, Haley E. York
LSU Master's Theses
The purpose of the current study was to determine the effectiveness of a manualized, universal social skills intervention for young students. Past research on the use of universal interventions within the domain of social skills has shown great promise, and the importance of social skills has been demonstrated through their empirical relation to academic and behavioral outcomes. Additional research has shown that, overall, social skills training interventions for young children are successful and have lasting effects. These findings convey the importance and need for effective, efficient, and early social skills training interventions. As such, this study used a quasi-experimental pretest-posttest …
An Examination Of The Stimuli Used In And The Theories Behind The Cross-Modal Stroop Task, Danielle A. Lutfi-Proctor
An Examination Of The Stimuli Used In And The Theories Behind The Cross-Modal Stroop Task, Danielle A. Lutfi-Proctor
LSU Master's Theses
The classic Stroop task, during which one names the ink color of color words, has long been used as a measure of selective attention (Stroop, 1935). Selective attention generally refers to our ability to attend to one stimulus (a target) while ignoring another (a distractor). Since its initial creation, many variations of the classic Stroop task have been developed. One of these variations is cross-modal Stroop, which uses visual colored targets and auditory distractor color words. However, whether the same mechanisms and processes are used while completing the two tasks has yet to be determined. The following thesis examined cross-modal …
Abnormal Emotional Experience In Schizophrenia, Dallas A. Callaway
Abnormal Emotional Experience In Schizophrenia, Dallas A. Callaway
LSU Master's Theses
Ambivalence is defined as the state of simultaneously experiencing antithetical emotions towards a single attitude object (Bleuler, 1911/1950). Recent studies have evidenced ambivalence as a prominent aspect of schizophrenia patients’ in-the-moment emotional experiences (Cohen & Minor, 2010; Trémeau et al., 2009). The present study extended this line of work through the use of an experimental mood-induction methodology to explore the amount, frequency, and average duration of univalent positive, negative, and ambivalent emotional episodes within individuals with schizophrenia and those without psychiatric disturbance. The results indicate that, when exposed to a film clip stimulus selected for its documented (Larsen & McGraw, …
Community Violence Exposure Among Underprivileged Adolescents : What Are The Buffering Effects Of Family Qualities On Negative Outcomes?, Katherine Marie Harrison
Community Violence Exposure Among Underprivileged Adolescents : What Are The Buffering Effects Of Family Qualities On Negative Outcomes?, Katherine Marie Harrison
LSU Master's Theses
Crime and violence are common in impoverished neighborhoods. Consequently, many youth are at risk for victimization and witnessing violent acts. Extensive research has established the presence of significant associations between violence exposure and aggression and posttraumatic stress symptoms among youth. Research has confirmed the protective role of several family characteristics against these negative outcomes despite adversity. However, the literature investigating the buffering effects of family in the relationship between community violence exposure and aggressive behavior and posttraumatic stress symptoms is limited. The current study examined the moderating effect of family factors such as household structure, social support, and parenting techniques …
Cognitive Performance As A Predictor Of Functional Capacity In Schizophrenia, Tracey Lauren Auster
Cognitive Performance As A Predictor Of Functional Capacity In Schizophrenia, Tracey Lauren Auster
LSU Master's Theses
Previous literature has demonstrated that persons with schizophrenia suffer from cognitive deficits and struggle with deficits in everyday living skills, two areas of functioning thatare related in some way. Nearly all cognitive domains are affected in schizophrenia, and most of them have been associated with poor functioning. Therefore, a possible link is the existence of an attentional bottleneck where the demands of attentional load and the lack of attentional resources to handle these demands, decreases capacity to carryout everyday living skills. Researchers have suggested the existence of a structural bottleneck that limits individuals’ ability in the use of cognitive resources. …
Comparing Social Skills In Children Diagnosed With Autism Spectrum Disorders According To The Dsm-Iv-Tr And The Proposed Dsm-5, Jennifer Susan Beighley
Comparing Social Skills In Children Diagnosed With Autism Spectrum Disorders According To The Dsm-Iv-Tr And The Proposed Dsm-5, Jennifer Susan Beighley
LSU Master's Theses
Autism Spectrum Disorder (ASD) is currently defined using criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR). With the fifth edition of the DSM (DSM-5) forthcoming, one change the American Psychiatric Association has proposed is an increase in the number of overall symptoms necessary to meet criteria for ASD. Because social skills is well established as a core symptom of autism, the present study explores differences in social functioning using the Matson Evaluation of Social Skills in Youngsters-II (MESSY-II) in three groups of children ages 3-16 years including those diagnosed with ASD using the …
Schizotypy: The Dynamic Relationship Between Trait And State Processes, Rebecca K. Macaulay
Schizotypy: The Dynamic Relationship Between Trait And State Processes, Rebecca K. Macaulay
LSU Master's Theses
Importantly, elevations in emotional reactivity to stress are often found in individuals vulnerable for psychosis. This study investigated several meaningful factors that appear to either increase vulnerability to stress (degree of schizotypy traits, trait negative affect, low perceived control, and impaired selective attention), or increase resiliency to stress (trait positive affect). A modified Posner spatial-cueing task utilizing affective cues was employed to assess selective attention within a neutral and an uncontrollable stressor condition. Between group differences (high, medium and low in schizotypy traits) and interactions between affective traits, state affect, and perceived control were evaluated in order to shed light …
Multi-Informant Investigation Of College Student Drinking Behaviors And Social Anxiety : The Role Of Perceived Descriptive And Injunctive Norms, Anthony H. Ecker
Multi-Informant Investigation Of College Student Drinking Behaviors And Social Anxiety : The Role Of Perceived Descriptive And Injunctive Norms, Anthony H. Ecker
LSU Master's Theses
Problematic alcohol use in college is a major public health concern. Identification of variables related to development of alcohol-related problems is an important research goal. Social anxiety and perceived social norms are two such variables. Social anxiety is associated with concurrent experience of alcohol-related problems and development of future problems with alcohol. Perceived norms, especially norms related to perceived approval of risky alcohol use (i.e., injunctive norms), are related to greater drinking problems among college students with higher social anxiety. College students typically overestimate the amount that other students in general use alcohol, and the discrepancy between perceived and actual …
Utilizing Students As Behavior Change Agents : An Example Using Check-In/Check-Out, Evan Henry Dart
Utilizing Students As Behavior Change Agents : An Example Using Check-In/Check-Out, Evan Henry Dart
LSU Doctoral Dissertations
While there is no shortage of evidence-based interventions designed to address the academic and behavioral difficulties of students in schools, it can be difficult to find adults that are available to implement them consistently. To remedy this problem, students’ peers have often been utilized effectively as academic interventionists in the schools and as behavioral interventionists for students with disabilities. Two studies were designed to investigate the effectiveness of a peer-mediated intervention for students at-risk for developing behavioral disorders. Check-in/Check-out (CICO), a mentor-based intervention traditional implemented by adults, was modified so that it could be easily implemented by elementary school students. …
An Examination Of Speech Characteristics Under Conditions Of Affective Reactivity And Variable Cognitive Load As Distinguishing Feigned And Genuine Schizophrenia, Gina M. Najolia
LSU Doctoral Dissertations
Proper assessment of schizophrenia is complicated by the need for clinicians to be cognizant of the possibility of malingering, i.e., the intentional production of false or grossly exaggerated symptoms, motivated by external incentives. Current standardized schizophrenia malingering detection methods rely on endorsement of improbable or exaggerated, mainly positive, symptoms. However, these detection methods may be vulnerable to successful manipulation by sophisticated malingerers, particularly if coached regarding response style assessment strategies. This paper explored the utility of supplemental variables to examine in schizophrenia malingering detection by using a simulation study design to compare schizophrenia patients, a community participant sample instructed to …
Creating An Sli Performance Profile With Load, Christy Marie Seidel
Creating An Sli Performance Profile With Load, Christy Marie Seidel
LSU Doctoral Dissertations
The purpose of this body of work was to gain a clearer understanding of the potential cognitive factors that may contribute to Specific Language Impairment (SLI). This study attempted to simulate a performance profile of SLI in typically developing children within a grammaticality judgment task, featuring structures historically difficult (third person singular –S and auxiliary BE) and easy (plural –S and progressive –ING) for individuals with SLI. Cognitive load was manipulated through the length of the sentences to be judged, and individual differences in phonological short term memory (PSTM) and working memory were measured (WM). For a successful simulation to …
