Change In Developmental Quotient In Toddlers Assessed For Autism Spectrum Disorder, Lindsey Willis Williams
Change In Developmental Quotient In Toddlers Assessed For Autism Spectrum Disorder, Lindsey Willis Williams
LSU Master's Theses
ASD is marked by significant delays in social and language development, while development in other areas, such as cognitive functioning, can be highly variable from person to person. Though preschool-aged children with ASD often exhibit a profile of developmental delays similar to children with other developmental disorders at a discrete moment in time, few studies have investigated possible differences in rate of skill acquisition in developmental domains in children with different disorders. Sensitive periods of development are marked by less stability in performance of developmental skills. Results of prior studies suggest that if appropriate early interventions are applied during sensitive …
The Effect Of Habituation And Changes In Cognition On Anxious Children's Performance On The Wisc-Iv, Franziska Noack
The Effect Of Habituation And Changes In Cognition On Anxious Children's Performance On The Wisc-Iv, Franziska Noack
LSU Master's Theses
Researchers have shown that children with anxiety disorders perform worse on intelligence tests than children with no diagnosable disorders. At this point, two theories have been put forth to describe the direction of this relationship: anxiety results in lowered test performance, and underlying cognitive deficits result in the development of anxiety. Lowered test performance as a result of anxiety may either be due to attention-deficits due to state anxiety or anxiety-elicited difficulties with long-term retention and learning. The purpose of this study was to further examine the first theory: that clinical levels of anxiety can hamper intelligence test performance in …
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 …
Feedback As A Source Of Criterion Noise In Recognition Memory, Bryan Franks
Feedback As A Source Of Criterion Noise In Recognition Memory, Bryan Franks
LSU Master's Theses
In two experiments, I investigated whether providing accuracy feedback on recognition memory tests affects discriminability of encoded targets from lures. The primary hypothesis was that feedback is a source of criterion noise which leads to lower discriminability. Additionally, it was predicted that separate sources of criterion noise might have additive effects. In both experiments, the presence of feedback was manipulated within-subjects. In Experiment 1, participants completed two recognition tests in which they made either “old/new” decisions or responded using an 8-point confidence scale. Feedback lowered discriminability for both response type conditions, although a slightly larger deleterious effect was observed in …
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 …
Effort-Based Decision-Making In Schizotypy, Jessica Elaina Mcgovern
Effort-Based Decision-Making In Schizotypy, Jessica Elaina Mcgovern
LSU Master's Theses
Avolition/apathy, defined as reduced initiation of or persistence in goal-directed behavior, is a pernicious, core negative symptom of schizophrenia. While deficits in effort-based decision-making have been proposed to underlie negative symptom deficits, it remains unknown whether subjective or objective motivation deficits are evident in individuals with elevated schizotypy, a trait associated with putative latent liability of developing psychosis. Thus, the present study examined whether and how objective and subjective motivation deficits manifest in individuals high (n = 57) versus low (n = 58) in schizotypy traits (based on a median-split of total experience scores on the Schizotypal Personality Questionnaire –Brief …
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 …
The Moderating Effect Of Gender On The Relationship Between Socialization And Internalizing Problems In Early Childhood, Hilary Lynn Adams
The Moderating Effect Of Gender On The Relationship Between Socialization And Internalizing Problems In Early Childhood, Hilary Lynn Adams
LSU Master's Theses
Researchers in the field of Autism Spectrum Disorders (ASD) have confirmed that comorbidities are a common problem among diagnosed individuals. Current estimates suggest that more than two thirds meet criteria for an additional diagnosis of psychopathology. In particular, rates of several internalizing problems (i.e., anxiety, depression) appear to be greater for individuals with ASD than their typically developing counterparts. However, little research has been conducted examining factors apart from autism symptomatology that could influence this prevalence difference. Additionally, it is well established that anxiety and depression are more common in females than males in the general population. However, few studies …
Effects Of Brief Motivational Interviewing On Motivation For Weight Loss, Krystal Marie Waldo
Effects Of Brief Motivational Interviewing On Motivation For Weight Loss, Krystal Marie Waldo
LSU Master's Theses
Obesity rates have continued to increase over the past decade with a current estimate of 35.7% of adults who are obese in the United States. Several behavioral weight loss programs are available to individuals, which typically lead to a 10% decrease in body weight; however, most individuals begin gaining weight after six months. Long-term weight maintenance interventions may be needed to help individuals keep the weight off and more cost-effective, and tailored weight-loss treatments need to be available. Motivation may play an important role in long-term weight maintenance. Self-determination theory (SDT; Deci & Ryan, 1995) states that it is important …
Autism Severity And Comorbid Symptoms In Children With Asd, Jina Jang
Autism Severity And Comorbid Symptoms In Children With Asd, Jina Jang
LSU Master's Theses
Individuals with autism spectrum disorder (ASD) are reported to evince high rates of comorbid symptoms. Co-occurring disorders among individuals with ASD are often difficult to assess and diagnose accurately. Also, comorbid conditions frequently exacerbate symptoms of ASD. Different treatment regimens may be effective for comorbid symptoms in ASD; however, research looking at comorbid symptoms and ASD is limited. The current study aimed to extend the literature in this area by examining the relationship between ASD and comorbid symptoms. First, the current study assessed how often and how severely comorbid symptoms were endorsed. Further, autism severity was used to predict comorbid …
Examination Of The Relationship Between School Climate And Other School-Based Factors And Teacher Self-Efficacy, Elise C. Mciver
Examination Of The Relationship Between School Climate And Other School-Based Factors And Teacher Self-Efficacy, Elise C. Mciver
LSU Master's Theses
Years of failed school reform speak to the need for a larger body of evidence that prioritizes the factors documented to be pivotal to student success. Research consistently demonstrates that teachers may be the most influential factor; therefore, it is necessary to critically understand the skills and personal competencies retained by highly effective teachers. One such competency is teacher self-efficacy, which is broadly defined as a belief in one’s abilities to influence student achievement. The construct has been shown to relate to a host of positive outcomes for both teachers and students. Given the significance of and implications for teacher …
Cognitive Bias And Learning From Experience: Reflective Processes For Reducing Bias, Dina Acklin
Cognitive Bias And Learning From Experience: Reflective Processes For Reducing Bias, Dina Acklin
LSU Master's Theses
While heuristic processing is often useful for quickly ascertaining information in everyday situations, it can lead to inaccuracies when task demands become complex and more systematic processing is required. These inaccuracies are often the result of confirmation bias, in which information that is consistent with our beliefs is noted at the expense of disconfirming evidence. The current decision making literature suggests that highlighting disconfirming evidence – termed negative feedback - might work to engage deliberate, systematic cognitive processes that lead to more accurate information acquisition. Using a probabilistic learning task where feedback is not consistently accurate (Matchmaker), the first experiment …
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 …
Examination Of The Differential Effectiveness Of Interdependent And Dependent Group Contingencies In Reducing Disruptive Behavior In The Classroom, Kelsey Lynn Hartman
Examination Of The Differential Effectiveness Of Interdependent And Dependent Group Contingencies In Reducing Disruptive Behavior In The Classroom, Kelsey Lynn Hartman
LSU Master's Theses
Disruptive behavior in the classroom negatively affects all students’ academic engagement, achievement, and behavior. Group contingencies have been proven effective in reducing disruptive behavior as part of behavior interventions in the classroom. The Good Behavior Game is a classwide intervention that employs an interdependent group contingency to diminish disruptive behavior. Previous research comparing the effects of the different group contingencies has been inconclusive, inconsistent or unable to rule out sequence effects. This study employed an alternating treatments design across 3 elementary classrooms to compare the effectiveness of interdependent and dependent group contingencies in decreasing disruptive behavior. Results showed that the …
Influencing The Allocation Of Attentional Resources In Tracking: Evidence For A Combined Parallel And Serial Mechanism, Justin Merrill Ericson
Influencing The Allocation Of Attentional Resources In Tracking: Evidence For A Combined Parallel And Serial Mechanism, Justin Merrill Ericson
LSU Doctoral Dissertations
The ability to track multiple moving objects (e.g. cars on a roadway, players and/or balls in a sporting event, pedestrians in a crowded space) has been thought to be a parallel process, such that all the objects are tracked simultaneously (Howe et al., 2010). Others have asserted that some serial mechanism is involved in the tracking process, suggesting that there are shifts of attention from object to object in order to successfully track (Oksama & Hyönä, 2008). Subsequent research has demonstrated that changes in trajectory can attract attention (Howard & Holcombe, 2010) and that these localized changes in trajectory negatively …
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 …
Examining The Boundary Conditions Between Cognitive Control And Interference Derived From Stimulus-Based And Response-Based Conflict, Jonathan D. Tall
Examining The Boundary Conditions Between Cognitive Control And Interference Derived From Stimulus-Based And Response-Based Conflict, Jonathan D. Tall
LSU Doctoral Dissertations
Cognitive control is a broad construct that defines a set of processes involved in maintaining task goals in response to interference. Working memory capacity (WMC) is a similarly defined construct that shares many overlapping functions with cognitive control. The studies presented used controlled forms of interference to identify limits, or boundary conditions, that could help clarify the relationship between cognitive control and WMC. Experiment 1 used context effects to manipulate how interference and cognitive control could overlap. A spatial Stroop/Simon task was used in which proportion congruency for each subset (e.g., Simon or spatial Stroop) was manipulated to produce a …
Differential Examination Of Disgust In Spider, Blood-Injection, And Contamination Fear: Self-Reported And Attention-Based Assessment Of Differences, Whitney Shay Jenkins
Differential Examination Of Disgust In Spider, Blood-Injection, And Contamination Fear: Self-Reported And Attention-Based Assessment Of Differences, Whitney Shay Jenkins
LSU Doctoral Dissertations
Biased attention toward threat has been demonstrated across anxiety disorders as well as among nonclinical samples. While such studies have produced findings of attentional bias for fear-related or threatening stimuli, other types of emotionally laden stimuli have been ignored. This study sought to examine the experience and impact of disgust on individuals experiencing various types of anxiety, which may play a more significant role than fear in some disorders such as obsessive-compulsive disorder (OCD) and some specific phobias. Specifically, this study examined self-reported disgust and attentional bias in relation to disgust and threatening stimuli. A modified dot-probe task with pictorial …
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 …
Construct Validity Of The Autism Spectrum Disorders-Child Version (Asd-C) And The Child Behavior Checklist (Cbcl), Kimberly Tureck Sheffield
Construct Validity Of The Autism Spectrum Disorders-Child Version (Asd-C) And The Child Behavior Checklist (Cbcl), Kimberly Tureck Sheffield
LSU Doctoral Dissertations
Previous researchers have demonstrated that Autism Spectrum Disorder (ASD) is related to increased prevalence of other psychological disorders. Comorbid disorders increase the difficulties in socialization and communication already experienced by children with ASD. These symptoms often require additional intervention techniques and should be identified as early as possible to beget the best prognosis. The Autism Spectrum Disorders – Child Version (ASD-C) is an informant based assessment battery specifically designed to measure symptoms of ASD, comorbid disorders, and challenging behavior in children with ASD. The reliability and validity of this assessment has been established in previous studies, but there is no …
What To Expect When You're Expecting: Gaps In Utility Perceptions Of The Online Adult Learner, Byron Shane Lowery
What To Expect When You're Expecting: Gaps In Utility Perceptions Of The Online Adult Learner, Byron Shane Lowery
LSU Master's Theses
The adult learner can be defined as someone who, while enrolled in an academic institution, is involved in other major life responsibilities such as work or family obligations. Recently, there has been an increase in the number working adults pursuing a college education. However, empirical research regarding the job-related utility of obtaining this education is limited. Therefore, it is becoming increasingly important to examine not only the expectations regarding how a degree may be useful for career advancement, but the work and life outcomes associated with obtaining the degree as well. This study examined job-related utility perceptions for obtaining an …
Fixed-Time Schedule Effects On Participant Responding: An Evaluation Of Similar Vs. Dissimilar Schedule Programs Using A Group Design Approach, Jessica Pearl Alvarez
Fixed-Time Schedule Effects On Participant Responding: An Evaluation Of Similar Vs. Dissimilar Schedule Programs Using A Group Design Approach, Jessica Pearl Alvarez
LSU Doctoral Dissertations
We evaluated the effectiveness of fixed-time (FT) schedules of reinforcement at eliminating participant’s responding using a between-subjects group design. Participants experienced one of three conditions; a FT leaner schedule, a FT yoked schedule, or a FT denser schedule using a computerized experimental program. Dependent variables of interest are the total number of responses made during the fixed-time reinforcement phase and the latency until the participant met extinction or exit criteria.
Premature Birth As A Factor In Autism Spectrum Disorder, Rachel Lichtenstein Goldin
Premature Birth As A Factor In Autism Spectrum Disorder, Rachel Lichtenstein Goldin
LSU Master's Theses
Autism Spectrum Disorder (ASD) is characterized by pervasive delays in socialization, communication, and repetitive behaviors and restricted interests. While there is a growing body of evidence on the etiology of ASD, there are a limited number of studies examining factors which may impact the differentiation of ASD compared to other developmental disabilities. Additionally, few studies have examined factors which may predict level of ASD symptom severity. The primary aim of this study was to investigate whether premature birth occurs more commonly in infants and toddlers (17-37 months) with ASD than those with atypical development. A secondary aim of this study …
Multivariate Generalizability Of Writing Curriculum-Based Measurement (Cbm): An Examination Of Form, Occasion, And Scoring Method, Katherine Hunter Chenier
Multivariate Generalizability Of Writing Curriculum-Based Measurement (Cbm): An Examination Of Form, Occasion, And Scoring Method, Katherine Hunter Chenier
LSU Doctoral Dissertations
Curriculum-based measurement (CBM) is an assessment technique that has become increasingly popular in schools, gaining importance with the recent national emphasis on school and teacher accountability for student achievement. CBM is used to monitor student performance to provide an indicator of which students are at-risk of not achieving grade level standards and thus are in need of intervention. CBM is easy to administer, utilizes standard procedures, and provides measures indicative of general achievement in various domains. The utility of CBM to measure student ability in writing has been well-established. However, there is a paucity of technical adequacy research for writing …
