Estimation Of Premorbid Intelligence: A Combined Demographic And Psychometric Approach., Sandra Cook Friedberg
Estimation Of Premorbid Intelligence: A Combined Demographic And Psychometric Approach., Sandra Cook Friedberg
LSU Historical Dissertations and Theses
A combined demographic and present abilities approach to estimate premorbid intellectual functioning was developed and cross validated on unimpaired and closed head injured subjects. The non-clinical sample included 75 non-neurologically impaired individuals divided into two groups. The development sample (n = 50) was used to generate linear regression equations to estimate WAIS-R IQs from the estimated Barona IQ score (Barona, Reynolds, & Chastain, 1984) plus error score on the National Adult Reading Test (NART; Nelson, 1982). The cross-validation sample (n = 25) were individually matched to the clinical subjects on age, education, gender, and race variables. The clinical sample included …
Blood Pressure Reactivity And Emotion Among Borderline Hypertensives, Mild Hypertensives, Diabetic Hypertensives, And Normotensives., Alicia G. Pellegrin
Blood Pressure Reactivity And Emotion Among Borderline Hypertensives, Mild Hypertensives, Diabetic Hypertensives, And Normotensives., Alicia G. Pellegrin
LSU Historical Dissertations and Theses
The purpose of this study was to examine the relationship between emotion and blood pressure levels and variability for 80 Caucasian subjects between the ages of 30 and 65 matched on gender. The subjects were divided into four groups: normotensives, untreated borderline essential hypertensives, treated mild essential hypertensives, and Type II diabetic hypertensives. Subjects completed five psychological measures: the Beck Depression Inventory (BDI); State-Trait Anxiety Inventory-trait anxiety (STAI-Tanx); State-Trait Anger Expression Inventory-trait anger (STAXI-Tang); the ratio of anger-in to anger-out (STAXI-IO); and the Autonomic Nervous System Response Inventory (ANSRI). Subjects then recorded their home blood pressures seven times throughout the …
Structural Equation Modeling Analysis Of Risk Factors For The Development Of Eating Disorder Symptoms In Adolescents., Susan Elizabeth Barker
Structural Equation Modeling Analysis Of Risk Factors For The Development Of Eating Disorder Symptoms In Adolescents., Susan Elizabeth Barker
LSU Historical Dissertations and Theses
Risk factors which have been shown to influence the development of body dissatisfaction and eating disturbance in adolescents include depressed mood, low self-esteem, a history of teasing about physical appearance, social and parental pressure to be thin, pubertal timing, and actual body weight or body mass index. In the present study, an etiological model was proposed with these risk factors as predictors of the presence of eating disorder symptoms; this association was hypothesized to be mediated by dissatisfaction with body shape and weight. Structural equation modeling was used to test this theoretical model within a total sample of 345 adolescent …
Bombesin-Induced Hypothermia At Normal Ambient Temperatures: Contribution Of The Sympathetic Nervous System., John Christopher Barton
Bombesin-Induced Hypothermia At Normal Ambient Temperatures: Contribution Of The Sympathetic Nervous System., John Christopher Barton
LSU Historical Dissertations and Theses
Bombesin is a tetradecapeptide first isolated from frog skin. This peptide has potent effects on core body temperature of rats when administered centrally. Bombesin-induced hypothermia at normal ambient temperatures appears to be dependent upon some pre-existent condition which may be related to nutritional status. Four experiments were conducted to examine if the pre-existing condition for bombesin-induced hypothermia at normal ambient temperatures is primarily related to modulation of sympathetic nervous system activation. Experiment I demonstrated that central bombesin resulted in hypothermia in rats tested at normal ambient temperatures under conditions of ad-libitum access to food only when injected peripherally with the …
Factors Affecting Intended Self-Referral To An Employee Assistance Program., Paul Richard Damiano
Factors Affecting Intended Self-Referral To An Employee Assistance Program., Paul Richard Damiano
LSU Historical Dissertations and Theses
Using data from 256 subjects from three organizations which all had employee assistance programs (EAP), this study explored factors hypothesized to affect the likelihood for employees to self-refer to the EAP. Using both correlational data and a 2 x 2 x 2 x 5 repeated measures ANOVA, it was found that perceived confidentiality, reputation of the program, perceived problem seriousness, and type of problem (job, financial, health, psychological, or relationship) were significantly related to the intent to self-refer. There was also evidence that perceived controllability of the problem and a job performance decrement influenced the propensity to self-refer. An additional …
Hemispheric Function In Motor Skill Learning., Malcolm Maccoll Fairweather
Hemispheric Function In Motor Skill Learning., Malcolm Maccoll Fairweather
LSU Historical Dissertations and Theses
Neuropsychological research examining hemispheric function has recently revealed important, and previously unrecognized, perceptual-motor processing advantages in the left and right hemispheres of the brain. This research has also highlighted verbal-motor disruption problems in the performance of motor skills that may be predictable given an understanding of hemispheric specialization and function. Applied research examining methodology to optimize brain functioning in the learning of motor skills has ignored this neuropsychological research. Instead, applied research interest has focussed upon an individual difference phenomenon known as hemisphericity, which affects approximately 25% of the population. An individual presenting hemisphericity appears biased toward a left or …
A Comparison Of Verbal And Nonverbal Relaxation Induction Techniques In Neurologically Impaired Rehabilitation Patients., Warren Turner Jackson Iii
A Comparison Of Verbal And Nonverbal Relaxation Induction Techniques In Neurologically Impaired Rehabilitation Patients., Warren Turner Jackson Iii
LSU Historical Dissertations and Theses
This study compared the relaxation responses of neurologically impaired rehabilitation patients during verbal and nonverbal relaxation induction protocols. Seventy inpatients undergoing rehabilitation served as voluntary participants: (a) 20 patients with right-hemisphere brain dysfunction, (b) 20 patients with left-hemisphere dysfunction, and (c) a contrast group of 30 non-neurologically impaired orthopedic/medical patients. In the first phase of the study, all subjects underwent an evaluation that involved completion of screening instruments, self-report measures, and a brief neuropsychological test battery. In the second phase of the study, all subjects underwent two successive relaxation induction protocols: (a) verbal, and (b) nonverbal. Order of presentation was …
Development Of A Body Image Assessment Procedure For Children And Pre-Adolescents., Staci Veron Guidry
Development Of A Body Image Assessment Procedure For Children And Pre-Adolescents., Staci Veron Guidry
LSU Historical Dissertations and Theses
Eating disorders have been researched extensively among adult, and, more recently, among adolescent populations. Body image disturbance is included as a diagnostic criterion for anorexia nervosa and bulimia nervosa, and has been postulated as a central characteristic of the eating disorders. Researchers have identified eating disorders among prepubertal children; therefore, there is a need for the development of reliable and valid measures of eating disorders and body image in children. In this investigation, a total of 257 children in grades 3 through 7 completed the Children's Eating Attitudes Test, Children's Depression Inventory, Piers-Harris Children's Self Concept Scale physical appearance and …
Explicit Memory Bias For Body-Related Stimuli In Eating Disorders., Shannon Buckles Sebastian
Explicit Memory Bias For Body-Related Stimuli In Eating Disorders., Shannon Buckles Sebastian
LSU Historical Dissertations and Theses
This investigation studied the presence of an explicit memory bias for emotional body related stimuli in patients diagnosed with an eating disorder. Explicit memory refers to the recall of stimuli previously presented. Explicit memory tasks are thought to reflect cognitive elaboration mechanisms. Research on depressed patients has found a bias for recalling negatively valenced information and/or a bias against recalling positively valenced information. This study sought to extend this type of memory bias research to eating disorder patients. Three groups were examined, a group of clinical eating disordered women (n = 30), a group of weight preoccupied non-eating disordered individuals …
Validation Study Of The Teacher Ratings Of Individual Student Skills And Achievement (Trissa)., Wayne Thomas Stewart
Validation Study Of The Teacher Ratings Of Individual Student Skills And Achievement (Trissa)., Wayne Thomas Stewart
LSU Historical Dissertations and Theses
The purpose of this study was to assess the concurrent, predictive, and discriminant validity of the Teacher Ratings of Individual Student Skills and Achievement (TRISSA). The TRISSA was developed in three major phases. Phase I consisted of the generation of an item pool and review of these items by experts. Phase II involved teachers completing the original 100-item TRISSA and subjecting data to a factor analytic study. Based on the factor analysis of 1,049 cases, a revised TRISSA (i.e., TRISSA-36) was produced. The TRISSA-36 was administered to teachers as part of actual pupil appraisal evaluations in three parishes in southeastern …
An Investigation Of Behavior Problems Of Children With Down Syndrome And Their Relationship To Life Events., David Alan Coe
An Investigation Of Behavior Problems Of Children With Down Syndrome And Their Relationship To Life Events., David Alan Coe
LSU Historical Dissertations and Theses
Behavior problems of 44 children with Down Syndrome between the ages of 6 and 15 and 44 controls without mental retardation matched for age, sex and socioeconomic status were compared by means of mother and teacher ratings. Ratings from both sources indicated that children with Down Syndrome had more behavior problems, in particular attention deficit, noncompliance, thought disorder and social withdrawal. Thirty one percent of these children were identified by mothers as having a significant behavior problem compared with 58% of those rated by teachers. In both cases, Down Syndrome behavior problem prevalence exceeded that for controls by a three …
Selective Information Processing Of Body Size And Food Related Stimuli In Women Who Are Preoccupied With Body Size., Richard Daniel Fuller
Selective Information Processing Of Body Size And Food Related Stimuli In Women Who Are Preoccupied With Body Size., Richard Daniel Fuller
LSU Historical Dissertations and Theses
Overconcern or preoccupation with body size and weight is a central psychopathological feature of the eating disorders. The overconcern with body size is considered to be a function of fear of weight gain or "fear of fatness". Cognitive theories of psychopathology have hypothesized that fear results in an increased activation of cognitive structures associated with the feared object. This increased activation (priming) is hypothesized to enhance the processing of information related to the feared object. This study tested this hypothesis using a lexical decision task. Individuals with extreme body size preoccupation were evaluated for a selective information processing of body …
Effects Of Threat-Related Emotional Information In A Lexical Decision Task: Examination Of Cognitive And Motor Performance., Sheryl Rene Jackson
Effects Of Threat-Related Emotional Information In A Lexical Decision Task: Examination Of Cognitive And Motor Performance., Sheryl Rene Jackson
LSU Historical Dissertations and Theses
Recently, attention has been given to the cognitive processing of aversive emotional, or threat-related, information. Although investigations have often focused on anxiety disordered individuals, it is suggested that examination of "normal" individuals with varying levels of anxiety will increase the understanding of the cognitive processing of aversive emotional, or threat-related, information. It has been hypothesized that high anxious individuals exhibit an attentional bias toward threat-related emotional information. The response of low anxious individuals to threat-related information is unclear. Some evidence suggests that non-anxiety disordered individuals employ a mechanism that inhibits or interferes with the processing of threat-related, emotional information. The …
Patterns Of Adaptive Functioning In Cortical And Subcortical Diagnostic Groups Of Dementia., Paul Matthew Dammers
Patterns Of Adaptive Functioning In Cortical And Subcortical Diagnostic Groups Of Dementia., Paul Matthew Dammers
LSU Historical Dissertations and Theses
Much debate exists as to the independence of subcortical dementia as a recognizable clinical entity. Researchers in the dementia area seem to accept that cortical dementias are relatively more incapacitating than subcortical dementias. However, there are no empirical studies to support this claim. Impairment in adaptive functioning is one criterion to be met in the diagnosis of dementia according to DSM-III-R (APA, 1987) and NINCDS-ADRDA criteria (McKhann, Drachman, Folstein et al., 1984). However, a comparison of the degree of impairment in adaptive functioning between subcortical and cortical diagnostic groups of dementia has never been systematically and empirically investigated. This study …

The Impact Of Trait Anxiety On Slow-Wave Sleep Processes., Kristi Hulse Fuller
The Impact Of Trait Anxiety On Slow-Wave Sleep Processes., Kristi Hulse Fuller
LSU Historical Dissertations and Theses
The sleep of high anxiety/worry and low anxiety/worry subjects was studied by means of nocturnal polysomnography. Fifteen high anxiety adult subjects were chosen to represent an analog Generalized Anxiety Disorder (GAD) population, and were selected from among individuals scoring within the upper 20th percentile on the trait portion of the State-Trait Anxiety Inventory (STAI) and the Penn State Worry Questionnaire (PSWQ). Fifteen low anxiety subjects were selected from among individuals scoring within the lower 50th percentile on those measures, and were matched with high anxiety subjects for age, sex, race, and Beck Depression Inventory (BDI) scores. Analysis of polysomnography variables …
Cognitive Distortions, Impulsivity, And Stressful Life Events In Suicidal Adolescents., Christine Sadowski
Cognitive Distortions, Impulsivity, And Stressful Life Events In Suicidal Adolescents., Christine Sadowski
LSU Historical Dissertations and Theses
Among adolescents, escalating rates of completed and attempted suicide are reported worldwide (Maris, 1985). In the literature, a variety of risk factors have been associated with suicidality in adolescence. The purpose of this study was to examine the relationship between cognitive distortions, impulsivity, and stressful life events in suicidal adolescents. A total of 118 adolescents between the ages of 12 and 18 years participated in this investigation. The subjects comprised four groups: inpatient suicide attempters (n = 33); inpatient and outpatient suicide ideators (n = 17); inpatient, nonsuicidal controls (n = 33), and community high school controls(n = 35). Subjects …
