Women's Cognitive Appraisals Of Their Birth Experience As Predictive And Maintaining Factors Of Postpartum Posttraumatic Stress Symptom Severity, Lauren Carr Spooner

Dissertations

Empirical support has accumulated for evidence of posttraumatic stress symptoms following approximately 30% of childbirth experiences (Olde, van der Hart, Kleber, & van Son, 2006). Researchers have suggested that there is a complex relationship among predisposing, precipitating, and maintaining factors that impact postpartum PTSD (Slade, 2006). Anxiety, perception of support, and negative cognitions are such factors that have been shown to significantly correlate with PTSD symptoms (Foa & Rothbaum, 1998; Olde et al., 2006; Soet, Brack, & Dilorio, 2003), but have not been studied together in relation to PTSD associated with traumatic birth. The current study controlled for trait anxiety …

The Relations Among Laterality, Cortisol, And Approach-Avoidance Behavior In Garnett's Bushbaby (Otolemur Garnettii), David Burton Hanbury

Dissertations

Many studies to date have demonstrated that approach and avoidance behaviors are processed asymmetrically in the brain and may be reflected in measures such as handedness. The purpose of this study was to extend work in primates on this topic to Garnett’s bushbaby, a prosimian species. Furthermore, to determine whether measures in addition to handedness relate to approach-avoidance behavior, lateralized differences in tympanic membrane temperature were assessed. Cortisol measures were also obtained to determine whether it was related approach-avoidance behavior and handedness. Eleven captive-born Garnett’s bushbabies (Otolemur garnettii) were evaluated for handedness and responsiveness to novelty. Moreover, the …

A Moderational Model Investigating Child Temperament, Executive Functioning, And Contextual Predictors Of Externalizing Behaviors In Preschoolers, Ferne Arlene Pinard

Dissertations

Child externalizing behavioral problems (e.g., ADHD symptoms and aggressive behaviors) often appear early in life, are relatively stable, and are associated with maladaptive outcomes in many domains of functioning. Research has shown that, for a subset of children who demonstrate these early behavioral patterns, the course is often more pervasive and persistent. Consequently, a better understanding of externalizing behavioral problems during the preschool period is essential. The current study examined whether biologically-based correlates (i.e., child temperament and executive functioning/neurocognitive attention; EF/Attention) would moderate the relation between the contextual correlates (i.e., socioeconomic status and parenting practices) and externalizing behaviors (i.e., ADHD …

The Family Environment And Children With An Autism Spectrum Disorder: A Longitudinal Examination Of The Relation Between Parental Expressed Emotion And Child Externalizing Behaviors, Stephanie Bader

Dissertations

The current study, a longitudinal study using Bader (2009) as Time 1 data, used questionnaire data to explore the longitudinal relation between parental expressed emotion, a well-established predictor of symptom relapse in various other disorders (e.g., schizophrenia, bipolar, and behavior disorders), with change in externalizing behaviors in 84 children, ages 8 to 18, with an autism spectrum disorder (ASD). Both components of expressed emotion, criticism/hostility and overinvolvement, were explored, though hypotheses were only made in regard to criticism/hostility. It was found that high levels of parental criticism/hostility, not parental overinvolvement, at Time 2 uniquely related to higher levels of externalizing …

An Electrophysiological Examination Of Adhd-Associated Symptoms And Selective Attention In Adults, Erica Diane Prentkowski

Dissertations

A main component of Attention-Deficit/Hyperactivity Disorder (ADHD) is a deficit of inattention. This deficit causes impairment for both children and adults in a variety of settings including school and work. The current study examined auditory selective attention in a community sample of adults. It was the aim of this project to examine possible differences in selective attention for adults with high levels of ADHDassociated symptoms, when compared to adults with low levels of ADHD-associated symptoms, including conditions under which these differences may be an advantage. Specifically, it was expected that adults with high ADHD-associated symptoms would benefit from the high …

The Effects Of Facial Expression On Out-Group Discrimination, Charles Brendan Clark

Dissertations

The current paper sought to test the hypothesis that the facial expression of smiling would mitigate the effects of out-group discrimination. Study 1 examined the influence of facial expression (smiling or frowning), gender (man or woman), and race (Black or White) on resource allocation decisions. Participants were shown arrays of facial photographs. The arrays all contained eight photographs and were counterbalanced to contain all combinations of the variables of interest (i.e., each group had a smiling man of each race, a smiling woman of each race, a frowning man of each race, and a frowning woman of each race). The …

An Exploratory Investigation On The Effects Of An Electronic Recording System For Repeated Reading, Seajae Calvin Hartness

Dissertations

Repeated Reading is a common reading intervention that has been used to help students read fluently since 1979. There are many variations of Repeated Reading that have been investigated and found to be effective. However, there is a relative research deficit on the effectiveness of software programs for administering Repeated Reading. This exploratory research project examined the effectiveness of Repeated Reading with an electronic recording system. The performance of the electronic Repeated Reading group was compared to the performance of participants who received traditionally administered Early Intervention Program services. The results suggest that electronically scored Repeated Reading is as effective …

The Structure Of Equine Personality, Rachel Etta Kristiansen

Dissertations

The current study was designed to investigate the structure of equine personality. Two personality questionnaires were replicated from previous studies and implemented simultaneously to test the theory that different questionnaires may extract different personality structures. Breed and sex differences were also hypothesized to be significantly different for some personality dimensions. A total of 827 horses were rated on a 90-item personality questionnaire. Participants were recruited online via email and completed the survey at their own convenience. An additional 121 respondents rated a horse that had already been rated; these results were used to calculate inter-rater reliability.

After data collection was …
