Effects of a Play-Based Teacher Consultation (PBTC) Program on Interpersonal Skills of Elementary School Teachers in the Classroom

Description: The purpose of this study was to examine the effectiveness of a play-based teacher consultation (PBTC) program on individual teachers’ interpersonal classroom behaviors and teacher-child relationships. The research questions addressed the application of child-centered play therapy principles and PBTC increasing teacher responsiveness, decreasing teacher criticism, and enhancing teachers‟ perceptions of the teacher-child relationship in elementary school classrooms. Single-case design was utilized to examine eight teachers‟ perceptions over 16 weeks. The sample included 8 White female teachers from three local elementary schools. Teacher ages ranged from 28 to 59 years old. There were 5 kindergarten, 1 first grade, and 2 second grade teachers. The teachers participated in one educational training session followed by play sessions with children of focus and interactive modeling sessions. Trained observers, blind to the study’s purpose, utilized the Interaction Analysis System in classroom observations of the teachers, three times per week, to examine teachers’ interpersonal skills. Additionally, the teachers completed the Student Teacher Relationship Scale for the children of focus before and after the play session phase to examine change in the teacher-child relationship. Visual analysis of the data indicated the PBTC’s overall positive impact. 5 out of 8 teachers demonstrated increases in teacher responding scores at mildly to very effective criteria levels. All 8 teachers demonstrated decreases teacher criticism at effective to very effective criteria levels. The teacher-child relationships indicated mixed results, with 5 out of 8 teachers indicating positive changes in teacher-child relationships. Discussion includes implications for future research regarding single-case design, measurement of teacher change, and modifications of the PBTC model.

The Effects of a Programmed Teaching Sequence and Response Card Use with Systematic Feedback on the Acquisition of Time Telling Behavior of 3 Students with Intellectual Disability

Description: Few studies have proposed or evaluated methods to teach telling time. The purpose of this study was to evaluate the effects of differential reinforcement of student responding in the form of response cards to teach three middle school students with intellectual disability to tell time. Participants worked through six training phases. Results showed that correct responding increased from pre-assessment (range of 5.71-14.29% correct) to post-assessment (range of 85-100% correct). Preliminary evidence shows promise in the application of these procedures to teach telling time to middle school students with intellectual disability.

Effects of a Prototypical Training Program on the Implementation of Systematic Observational Data Collection on Iep Objectives for the Core Deficits of Autism Spectrum Disorders

Description: Legal mandates and best practice recommendations for the education of students with autism spectrum disorders (ASD) emphasize the importance of systematic, ongoing observational data collection in order to monitor progress and demonstrate accountability. The absence of such documentation in decision-making on instructional objectives indicates a weakness in bridging the research-to-practice gap in special education. Utilizing a multiple baseline design across participants, the current study evaluated the effects of a prototypical teacher training program (i.e., workshop, checklist, in-classroom training with feedback, and maintenance with a thinned schedule of feedback) on the frequency of data collection on core deficits of ASD and the use of data-based decision-making. Results indicate increases in daily mean frequency of data collection following intervention. Maintenance and generalization indicates variable responding across participants. Effect size (Cohen's d) indicates a large, clinically significant effect of the training program. Results are discussed in relation to training models, maintenance, and future research.

The Effects of a Psychosocial Environment on College Women’s Exercise Regulations and Social Physique Anxiety

Description: A positive psychosocial intervention comprised of high autonomy support, task-involvement, and caring was implemented in physical activity classes to examine its effects on college women’s basic psychological needs (i.e. autonomy, competence, relatedness), exercise regulations (i.e. external, introjected, identified, integrated, intrinsic) and social physique anxiety (SPA). We hypothesized that at the end of the semester, participants in the intervention group (N = 73) would report greater need satisfaction, more self-determined regulations and less SPA than participants in the non-intervention group (N = 60). At T1 and T2, both the intervention and non-intervention participants reported “agreeing” with experiencing an autonomy supportive, task-involving, and caring environment. Furthermore, both groups at T1 and T2 reported moderate SPA. No significant group differences were found at T1. At T2, significant group differences were observed in the intervention and non-intervention groups’ report of external regulation and intrinsic regulation. The results suggests that group exercise instructors are capable of creating a positive psychosocial environment to enhance students’ intrinsic motivation.

Effects of a Self-care Intervention for Counselors on Compassion Fatigue and Compassion Satisfaction

Description: This study investigated the impact of a psychoeducational and experiential structured counselor self-care curriculum, developed by Drs. Charles and Kathleen Figley, on compassion fatigue and the prevention of professional impairment as measured by the Professional Quality of Life (ProQOL), Version 5. Volunteer licensed professional counselors, supervisors, and interns from four children's advocacy centers in Texas were assigned to treatment group (n = 21; 20 females, 1 male; mean age 34.4 years) or waitlist control group (n = 21; 19 females, 2 males; mean age 34.6 years). Participating counselors identified themselves ethnically as 64% Caucasian, 26% Hispanic, 7% African-American, and 2% Native-American. Employing a quasi-experimental design, three reliability-corrected analysis of covariance (ANCOVA) were utilized to analyze the data with an alpha level of .05 to assess statistical significance and partial eta squared to assess effect size. With pre-test scores as the covariate, results revealed in the experimental group a statistically significant reduction with large treatment effect for burnout (p = .01; partial ?2 = .15), a statistically nonsignificant reduction with a medium effect for secondary traumatic stress (p = .18; partial ?2 = .05), and a statistically nonsignificant increase with a medium effect for compassion satisfaction (p = .06; partial ?2= .09). Findings supported the use of this curriculum to train counselors on self-care as required of professional counselors by the American Counseling Association code of ethics and listed as a necessary skill in the standards of the Council for Accreditation of Counseling and Related Educational Programs.

The Effects of a Self-Monitoring Procedure on Sustainable Behavior

Description: Self-monitoring procedures are commonly used to assess environmentally sustainable behavior. The current experiment evaluated the effects of a self-monitoring procedure on two sustainable behaviors within a university office. A senior assistant was asked to report on light usage and energy-saver use on the copier in an office break room. Her reports were then compared with independent observations. Results showed that her reports were highly correspondent with independent observations although no change in target behaviors occurred. Changes in behavior occurred when she was asked to engage in the target behaviors. Results suggest that although self-monitoring procedures can correctly assess sustainable behaviors, they may not be suitable for behavior change.

Effects of a Water Conservation Education Program on Water Use in Single-family Homes in Dallas, Texas

Description: The City of Dallas Environmental Education Initiative (EEI) is a hands-on, inquiry-based, K-12 water conservation education program that teaches students concepts about water and specific water conservation behaviors. Few descriptions and evaluations, especially quantitative in nature, of water conservation education programs have previously been conducted in the literature. This research measured the quantitative effects and impacts of the education program on water use in single-family homes in Dallas, Texas. A total of 2,122 students in 104 classrooms at three schools in the Dallas Independent School District received hands-on, inquiry-based water conservation education lessons and the average monthly water use (in gallons) in single-family homes was analyzed to measure whether or not there was a change in water use. The results showed that over a period of one calendar year the water use in the single-family homes within each school zone and throughout the entire research area in this study experienced a statistically significant decrease in water use of approximately 501 gallons per home per month (independent, t-test, p>0.001). Data from this research suggests that EEI is playing a role in decreasing the amount of water used for residential purposes. Additionally, this research demonstrates the use of a quantitative tool by which a water conservation education program’s effect on behavior change can be measured. This research shows great promise for reducing use and increasing the conservation of our world’s most precious resource.

The Effects of Adlerian Play Therapy on Maladaptive Perfectionism and Anxiety and in Children

Description: I used singlecase A-B-A experimental design to examine the effectiveness of Adlerian play therapy (AdPT) for children identified with clinical levels of perfectionism on the Conners Parent Rating Scale-Revised and Conners Teacher Rating Scale-Revised. Participants were 2 children, a 10 year-old Hispanic male and a 7 year-old Caucasian female. To examine the effect of AdPT on maladaptive perfectionism and anxiety, the Child-Adolescent Perfectionism Scale and the Revised Children’s Manifest Anxiety Scale were administered to the children twice weekly over 3 phases of the study: baseline (6 administrations), intervention (12-16 administrations), and maintenance (6 administrations) for a total of 24 to 29 data points. Additionally, parents and teachers completed the Conners Rating Scales-Revised5 times: (1) prior to study, (2) following baseline/prior to treatment, (3) midpoint of treatment, (4) following treatment, and (5) following maintenance phase.During the intervention phase, the male and female participants attended 21 and 16 play therapy sessions, their mothers attended 6 and 5 parent consultations, and their teachers attended 6 and 3 teacher consultations, respectively. Analysis of the child self-report assessments indicated mixed and inconclusive results regarding the effects of AdPT on target behaviors. However, results of the parent and teacher reports indicated clinically significant reductionsin maladaptive perfectionism and anxiety over the five points of measurement for both participants. The participants’ maladaptive perfectionism moved from the clinical to the normal range. Implications for practice and future research are indicated.

Effects of Adult Romantic Attachment and Social Support on Resilience and Depression in Patients with Acquired Disabilities

Description: The acquirement of a disability (e.g., spinal cord injury, traumatic brain injury, amputation, multi trauma) is a risk factor for psychological disturbance (e.g., depression). Research has established that social support and secure attachment are protective factors against psychological disturbance. Attachment patterns have also been associated with differences in perceived social support. Secure attachment and higher perceived social support have been implicated in greater levels of resilience but need to be validated with a population of individuals who have acquired a disability. The Experiences in Close Relationships, Social Provisions Scale, Connor-Davidson Resilience Scale, Personal Health Questionnaire - 9 Depression Scale, and a Demographic were administered to 102 adult inpatients at a rehabilitation hospital undergoing an individualized rehabilitation program. Two MANOVAs were conducted to examine the direct associations of attachment classifications with the major dependent variables, as well as the various social support subscales. Path analysis tested two mediational models suggested by literature. Model 1 assessed the mediating role of attachment anxiety and attachment avoidance on the effect of social support on depression and resilience. Model 2 assessed the mediating role of social support on the effect of attachment anxiety or attachment avoidance on depression and resilience. Partial support was obtained for both models based on fit indices. A small but significant difference in the fit of the models was found, favoring Model 1. Clinical and research implications for this population and the limitations of the study are discussed.

The Effects of Air Pollution on the Intestinal Microbiota: A Novel Approach to Assess How Gut Microbe Interactions with the Environment Affect Human Health

Description: This thesis investigates how air pollution, both natural and anthropogenic, affects changes in the proximal small intestine and ileum microbiota profile, as well as intestinal barrier integrity, histological changes, and inflammation. APO-E KO mice on a high fat diet were randomly selected to be exposed by whole body inhalation to either wood smoke (WS) or mixed vehicular exhaust (MVE), with filtered air (FA) acting as the control. Intestinal integrity and histology were assessed by observing expression of well- known structural components tight junction proteins (TJPs), matrix metallopeptidase-9 (MMP-9), and gel-forming mucin (MUC2), as well known inflammatory related factors: TNF-α, IL-1β, and toll-like receptor (TLR)-4. Bacterial profiling was done using DNA analysis of microbiota within the ileum, utilizing 16S metagenomics sequencing (Illumina miSeq) technique. Overall results of this experiment suggest that air pollution, both anthropogenic and natural, cause a breach in the intestinal barrier with an increase in inflammatory factors and a decrease in beneficial bacteria. This evidence suggests the possibility of air pollution being a potential causative agent of intestinal disease as well as a possible contributing mechanism for induction of systemic inflammation.

Effects of Airway Pressure, Hypercapnia, and Hypoxia on Pulmonary Vagal Afferents in the Alligator (Alligator Misssissippiensis)

Description: The American alligator (Alligator mississippiensis) is an aquatic diving reptile with a periodic breathing pattern. Previous work has identified pulmonary stretch receptors (PSR), both rapidly- and slowly-adapting, and intrapulmonary chemoreceptors (IPCs) that modulate breathing patterns in alligators. The purpose of the present study was to identify the effects of prolonged lung inflation and deflation (simulated dives) on PSR and/or IPC firing characteristics in the alligator. The effects of airway pressure, hypercapnia, and hypoxia on dynamic and static responses of pulmonary stretch receptors (PSR) were studied in juvenile alligators (mean mass = 246 g) at 24°C. Receptor activity appeared to be a mixture of slowly-adapting PSRs (SARs) and rapidly-adapting PSRs (RARs) with varying thresholds and degrees of adaptation, but no CO2 sensitivity. Dives were simulated in order to character receptor activity before, during, and after prolonged periods of lung inflation and deflation. Some stretch receptors showed a change in dynamic response, exhibiting inhibition for several breaths after 1 min of lung inflation, but were unaffected by prolonged deflation. For SAR, the post-dive inhibition was inhibited by CO2 and hypoxia alone. These airway stretch receptors may be involved in recovery of breathing patterns and lung volume during pre- and post-diving behavior and apneic periods in diving reptiles. These results suggest that inhibition of PSR firing following prolonged inflation may promote post-dive ventilation in alligators.

The Effects of Attributional Styles on Perceptions of Severely Mentally Ill Offenders: a Study of Police Officer Decision-making

Description: Police officers are allowed considerable discretion within the criminal justice system in addressing illegal behaviors and interpersonal conflicts. Broadly, such resolutions fall into two categories: formal (e.g., arrest) and informal outcomes. Many of these interventions involve persons who have historically faced stigmatization, such as those who have mental disorders, criminal histories, or both (i.e., mentally disordered offenders). On this point, stigma generally includes discriminatory behavior toward the stigmatized person or group and can be substantially influenced by internal and external attributions. In addition, researchers have suggested that internal attributions lead to punishing behaviors and external attributions lead to helping behaviors. The current study examined attributions about offender behavior made by police officers in an effort to evaluate the effectiveness of Corrigan’s model. Specifically, this study investigated the effects of officer attributions on their immediate decisions in addressing intentionally ambiguous and minor offenses. Officers provided one of two vignettes of a hypothetical offender who was either mentally disordered or intoxicated and provided their anticipated resolution of the situation. Encouragingly, disposition decision differed by offender condition, with a substantially higher rate of arrests for the intoxicated offender (i.e., the external condition). Corrigan’s model was initially successful for both offender conditions, but was overall more successful for the mentally disordered condition. Results are discussed within the broader context of police policy, such as crisis intervention training, and identification of officers who could benefit from additional mental health trainings.

Effects of Auditor-provided Tax Services on Book-tax Differences and Investors’ Mispricing of Book-tax Differences

Description: In this study, I investigate the effect of auditor-provided tax services (ATS) on firms’ levels of book-tax differences and investors’ mispricing of book-tax differences. The joint provision of audit and tax services has been a controversial issue among regulators and academic researchers. Evidence on whether ATS improve or impair the overall accounting quality is inconclusive as a result of the specific testing circumstances involved in different studies. Book-tax differences capture managers’ earnings management and/or tax avoidance intended to maximize reported financial income and to minimize tax expense. Therefore, my first research question investigates whether ATS improve or impair audit quality by examining the relation between ATS and firms’ levels of book-tax differences. My results show that ATS are negatively related to book-tax differences, suggesting that ATS improve the overall audit quality and reduce aggressive financial and/or tax reporting. My second research question examines whether the improved earnings quality for firms acquiring ATS leads to reduced mispricing of book-tax differences among investors. Recent studies document that despite the rich information about firms’ future earnings contained in book-tax differences, investors process such information inefficiently, leading to systematic pricing errors among firms with large book-tax differences. My empirical evidence indicates that ATS mitigate such mispricing, with pricing errors being lower among firms acquiring ATS compared with firms without ATS. Collectively, these results support the notion that ATS improve audit quality through knowledge spillover. Moreover, the improved earnings quality among firms acquiring ATS in turn helps reduce investors’ mispricing of book-tax differences.

Effects of Board Training on the Relationship Between Board Members and CEOs

Description: The purpose of this study is to ascertain the opinions of chief executive officers (CEOs) and school board chairs of Texas private schools in educational service center (ESC) Regions 10 and 11 toward board training and the potential benefits for the success of their respective roles. Literature regarding private school board training is limited. As a result, most private school boards face challenges regarding school board training expectations, which could affect their roles and the roles of CEOs. The quantitative and qualitative cross-sectional research design examined Texas private school CEOs’ and school board chairs’ perceptions about school board training and the working relationships between Texas school CEOs and school boards. The researcher developed the survey and interview questions used in this study. Responses to a 4-point Likert-type scale instrument, short answer questions, and interviews were solicited from a population of private school CEO and school board chairs within ESC Regions 10 and 11 from schools with an enrollment of at least 100 students and that contained Grades 9 through 12. In-depth Interviews were conducted with 12 private school CEOs and 12 school board chairs with varying levels of school board training. The research findings indicate that board training does make a significant difference in the working relationships between CEOs and private school boards. The findings of this study may assist private school boards in addressing school board training and the components of such training, which would benefit the working relationships between CEOs and school boards, as well as the success of private schools.

Effects of Brain Brain Injury on Primary Cilia of Glial Cells and Pericytes

Description: Glial cells maintain homeostasis that is essential to neuronal function. Injury to the nervous system leads to the activation and proliferation of glial cells and pericytes, which helps to wall off the damaged region and restore homeostatic conditions. Sonic hedgehog is a mitogen which is implicated in injury-induced proliferation of glial cells and pericytes. The mitogenic effects of sonic hedgehog require primary cilia, but the few reports on glial or pericyte primary cilia do not agree about their abundance and did not address effects of injury on these cilia. Primary cilia are microtubule-based organelles that arise from the centrosome and are retracted before cells divide. Depending on cell type, proteins concentrated in cilia can transduce several mitotic, chemosensory, or mechanosensory stimuli. The present study investigated effects of stab wound injury on the incidence and length of glial and pericyte primary cilia in the area adjacent to the injury core. Astrocytes, polydendrocytes and pericytes were classified by immunohistochemistry based on cell-type markers. In normal adult mice, Arl13b immunoreactive primary cilia were present in a majority of each cell type examined: astrocytes, 98±2%; polydendrocytes, 87±6%; and pericytes, 79±13% (mean ± SEM). Three days post-injury, cilium incidence decreased by 24% in astrocytes (p< 0.008) and 41% in polydendrocytes (p< 0.002), but there was no significant effect in pericytes. Polydendrocytes labeled with the cell cycle marker Ki67 were less likely to have cilia compared to resting, Ki67- polydendrocytes. Considering post-injury rates of proliferation for astrocytes and polydendrocytes, it appears that resorption of cilia due to cell cycle entry may account for much of the loss of cilia in polydendrocytes but was not sufficient to account for the loss of cilia in astrocytes. Under normal conditions, astrocytes rarely divide, and they maintain non-overlapping territories. However, three days after injury, there was a 7-fold increase in ...

Effects of Bring Your Own Device Initiatives Related to Instructional Planning and Classroom Environment in Two Texas High Schools

Description: This study was an examination of 20 North Texas high school teachers' perceptions about the effects of bring your own device (BYOD) initiatives on instructional planning and classroom environment. The BYOD initiative at two high school campuses was studied through a qualitative approach, i.e. a collective case study. Data were collected through interviews, classroom observations, and reviews of participants' lesson planning documents. The findings indicated teachers had to plan for inequitable technology access, technology support, effective classroom management, and relevant content to support student learning effectively. Teachers participated in professional development focused on planning for student devices, effective use of instructional technology, and classroom management during this type of instruction. Results revealed that, during instruction that included students' devices, teachers believed student engagement and content retention were greater. Observation data also indicated that students were more engaged in the instruction. The interviews and classroom observations indicated that students assumed a more active role in their learning during these lessons, and teachers facilitated and provided more support as needed. Effective planning and classroom management were identified as key components in the success of this type of initiative. Overall, the study supports the necessity for relevant professional development for teachers and campus administrators to ensure the success of BYOD initiatives. Similarly, these two groups should work together to develop the campus framework to support BYOD technology in the classroom.

The Effects of Capturing and Searching on the Acquisition of a Simple Arm Position

Description: The present experiment compared two methods of training a simple arm position using auditory feedback: capture and search. The participants were four right-handed female college students. During capture, auditory feedback was delivered by the experimenter after the participant moved along a single axis into the target position. During search, auditory feedback was produced by the computer after the participant left clicked a mouse inside the target location. The results of a multi-element design showed that participants performed more accurately during capture training than search training. Pre-training and post-training probes, during which no auditory feedback was provided, showed similar fluctuations in accuracy across probe types. A retention check, performed seven days after the final training session, showed higher accuracy scores for search than capture, across all four participants. These findings suggest that TAGteach should incorporate an approach similar to search training to improve training outcomes.

Effects of CFT Legumine™ Rotenone on Macroinvertebrates in Four Drainages of Montana and New Mexico

Description: Rotenone is considered essential in the restoration of native fish populations; however, the technique is contentious and criticized, specifically concerning impacts to invertebrates. Knowledge of effects to non-target organisms is important for the management and conservation of fish populations. This thesis has two general objectives: (1) demonstrate the influence CFT Legumine™ rotenone has on benthic macroinvertebrates for restoration projects in Montana and New Mexico and (2) evaluate the immediate response by means of invertebrate drift. Chapters 2 and 4 incorporate results from four different restoration projects that examine benthic macroinvertebrate response. Results indicate treatment effects are minimal for Specimen and Cherry Creek projects in Montana. New Mexico projects, Comanche and Costilla Creek suggest a greater influence. Potassium permanganate used to neutralize rotenone, influenced communities in three of the four projects. Regardless, invertebrates in all four projects recovered one-year after treatment. Chapter 3 examines macroinvertebrate drift during rotenone treatment. Results suggest a delayed response compared to previous literature. Rotenone appears to have the greatest immediate influence on the early life stages of Ephemeroptera and Plecoptera. To reduce impacts of rotenone to invertebrates, managers should apply CFT Legumine and use the minimal dosage and duration to complete the projects goal of removing non-indigenous fish species.

Effects of Child Development Associate Credential System 2.0 on Candidate Success Rates

Description: The purpose of this research was to identify the impact of process changes that have been made to the Child Development Associate (CDA) credential, which is a beginning early childhood teacher credential that focuses on competency based standards widely seen as necessary for early childhood teachers to possess. The process in which early childhood teachers receive their credential changed in 2013 with the implementation of CDA credential 2.0. Changes included taking a computerized exam and the implementation of a professional development specialist conducting an on-site classroom observation. In order to determine the impact that CDA 2.0 had on teacher credentialing success rates, a mixed-method sequential design was employed. First, existing data sets of success rates from a national scholarship program were reviewed. Following, interviews with CDA credential seekers were conducted. Findings revealed that while candidate success rates increased for those receiving CDA credentials under the 2.0 system, the actual number of candidates receiving scholarships to pursue the CDA credential through the national scholarship program decreased. Qualitative analysis of the semi-structured interviews indicated that three areas that impacted CDA 2.0 candidate success rates were the professional education programs and instructors, the CDA Exam, and Professional Development Specialists. This is the first research study to examine the CDA credential process. The findings demonstrate that the 2.0 system provides candidates with necessary supports to be successful. A significant question arising out of the data is how a determination is made to issue a credential. Before QRIS and public policy initiatives employ more efforts to professionalize the field of early childhood – primarily through the CDA credential – the process by which one obtains a credential should be more thoroughly examined.

The Effects of Child Parent Relationship Therapy (CPRT) for Adoptive Families

Description: Adoptive parents often struggle to understand and meet the social-emotional behavioral needs of their adopted child, particularly when the child's pre-adoption experience lacked a secure relationship with an attuned and responsive caregiver. This randomized controlled study, a replication of Carnes-Holt and Bratton's 2014 research, investigated the effects of child parent relationship therapy (CPRT) for adoptive families who reported attached-related concerns such as difficulties establishing a mutually satisfying parent-child relationship as well as concerns about the adopted child's behavior and parental stress. Participants were 49 adoptive parents (61% female; 7% couples; 86% European American, 6% Latino, 6% Asian, and 2% Black American) with adoptees between the ages of 2.5 to 9 (50% female; 35% European American, 22% Asian, 12% Latino, 10% Black American, and 21% Biracial or other). Eighty-four percent of children were adopted internationally or from the foster care system. Parents were randomly assigned to CPRT or treatment as usual (TAU). Results from 2 (group) by 2 (time) repeated measures ANOVAs indicated that compared to the TAU control group, parents who participated in CPRT reported statistically significant improvement in child behavior problems, parent-child relationship stress, and parental empathy, with a large treatment effects on all measures. Findings confirmed results from Carnes-Holt and Bratton's study and provided strong support for CPRT as a responsive intervention for adoptive parents and their children.

Effects of Conditional Discrimination Training on Symmetry and Semantic Priming

Description: Psychologists interested in the study of language find that people are faster at making decisions about words that are related than they are at making decisions about words that are not related – an effect called semantic priming. This phenomenon has largely only been document in laboratory settings using natural languages as contest and real words as stimuli. The current study explores the relation between the semantic priming effect and a laboratory procedure designed to give rise to performances that can be described as linguistic. Six adult participants learned to partition a collection of eight stimuli into two sets of four stimuli. Following this, the subjects showed the semantic priming effect within a set of stimuli but not across sets. These data suggest that it may be possible to study linguistic phenomenon in laboratory-based procedures allowing better control and the ability to ask very precise questions about linguistic functioning.

The Effects of Copying Before, Copying After, and Guessing on Acquisition Rate and Retention

Description: Computer-based instructional programs are being used more frequently in classrooms. While these programs offer many benefits from traditional teaching methods, humans still need to program them. There is inconsistency in the literature regarding the best way to design such programs. The purpose of this study was to evaluate the effects of three training procedures in teaching individuals to type a specified three-letter response in the presence of a corresponding symbol. Results show that the training format that prompted individuals to copy the correct response before the opportunity to respond was more efficient than viewing the correct response after an error, or copying the correct response after an error. A discussion of the results as well as implications for classroom use is also provided.

The Effects of Defensiveness and Social Desirability on the Reporting of Personality Traits

Description: Psychological assessment relies on accurate and forthright reporting to determine valid clinical presentations. However, it has long been recognized that examinees may be motivated to present a "better picture" through Positive Impression Management (PIM). Within the PIM domain, two distinct motivations (i.e., defensiveness and social desirability) emerge that have not been clearly differentiated in empirical literature. This thesis addressed the research gap for detecting PIM distortion of personality pathology, utilizing the Personality Inventory for DSM-5 (PID-5). In this investigation, 106 psychiatric inpatients were recruited from the adult Co-Occurring Disorders and Trauma Programs at University Behavioral Health. Using a mixed within- and between-subjects design, participants engaged in simulation via scenarios to be considered for a highly valued rehabilitation program (defensiveness) or employment (social desirability). As expected, inpatients showed elevated levels of problematic personality traits when reporting genuinely, but suppressed them under PIM conditions. These findings highlight that the PID-5, like all multiscale inventories, is highly vulnerable to intentional PIM distortion. Interestingly, respondents in the social desirability condition generally engaged in more total denial than those in the defensiveness condition. Empirically- and theoretically-based validity scales were developed to identify simulators and differentiate between conditions. Besides PIM, higher levels of experienced stigma were associated with more personality pathology, particularly the domain of Detachment. In addition, ancillary analyses showed strong convergence of the PID-5 with its hierarchical trait model to the DSM-IV categorical model. Continued research to detect PIM distortion, and more importantly to differentiate between PIM motivations, is essential for accurate clinical assessment of personality disorder traits and effective treatment planning.

Effects of Defensiveness on the Reporting of Personality Disorder Symptoms

Description: Personality disorders are not granted the same clinical attention accorded Axis I disorders despite their instrumental role in treatment and outcome. Even when standardized assessments are used, their clinical utility may be limited by an overly favorable self-presentation. The current study focused on defensiveness, the intentional denial of symptomatology, by examining individuals’ ability to minimize their presentation on personality disorder diagnostic measures. Using a within-subjects simulation design, dually diagnosed inpatients were assessed under both honest and defensive conditions. The study used self-report (Structured Clinical Interview for DSM-IV – Axis II – Personality Questionnaire, SCID-II-PQ) and interview-based (Structured Interview for DSM-IV Personality, SIDP-IV) diagnostic measures and a self-report measure of favorable self-presentation (Paulhus Deception Scales, PDS). The inpatients were quite capable of hiding maladaptive personality traits on diagnostic measures, with similarly large effect sizes on both the SCID-II-PQ and SIDP-IV. In addition to the PDS, two new detection strategies for identifying defensiveness showed promise.
