Evaluation Of A Progressive Model For Identifying Preferred Stimuli For Children With Developmental Disabilities, Amanda M. Karsten

Dissertations

Preference assessments for individuals with disabilities differ along many dimensions, including time requirements for implementation and probability of identifying a hierarchy of relative preferences. Some methods of assessment are also more conducive to use with individuals who exhibit problem behavior or certain prerequisite skills. Inaccurate results and loss of valuable treatment time are among the risks associated with selecting ineffective or unnecessarily lengthy procedures. The purpose of the current investigation was to evaluate a progressive model for conducting preference assessments which incorporates many of the aforementioned considerations. Concurrent-operant reinforcer evaluations were used to verify assessment findings. Based on 17 participants …

Unwanted Sexual Experiences: Preliminary Development And Validation Of A Behavioral Analog Measure For Risk Perception, Response Appraisal, And Response, Robin M. Carter-Visscher

Dissertations

Based on research findings indicating that sexual victimization is a prevalent problem on college campuses and has significant consequences for victims, researchers have examined the effectiveness of sexual assault education programs on reducing incidents of sexual victimization and have found programs to be unsuccessful. Other researchers have begun to investigate behavioral factors associated with risk for sexual victimization in order to better understand mechanisms of sexual victimization and revictimization before developing and implementing interventions. One hypothesis that has received increased attention in recent years is that women with a sexual victimization history may have deficient risk perception and effective responding …

Emotion Recognition And The Propensity To Engage In Sexually Coercive Behaviors: A Study With College Males, Beth J. Dietzel

Dissertations

Several variables have been investigated over the past years as risk factors for sexual aggression. Among them, substance use/abuse, family environment, attitudes towards women, and lack of empathy. Although researchers have identified several risk factors, predicting aggressive behaviors continues to be a difficult task. One variable that has received less attention in the literature is men's emotion recognition skills. Do men's emotion recognition skills affect their propensity to aggress?

The purpose of this study was to investigate emotion recognition skills/deficits and how such skills predict propensity to engage in sexually coercive behavior. There were two main goals of this study. …

Using Virtual Reality Enhanced Behavioral Skills Training To Teach Street-Crossing Skills To Children And Adolescents With Autism Spectrum Disorders, Tina R. Goldsmith

Dissertations

Children with Autism Spectrum Disorders (ASDs) often have poor safety skills due to their insensitivity to subtle environmental cues and poor problem solving in the face of stressful tasks. These skill deficits threaten their physical well-being and limit their personal independence. An effective intervention model for teaching safety skills is behavioral skills training (BST). The effects of this 4-part intervention, which includes Instructions, Modeling, Rehearsal, and Feedback, improve with the addition of in situ training. However, creating realistic, safe, and logistically feasible contexts for rehearsal of skills may prove difficult, if not impossible. Virtual reality (VR) may present a solution. …

The Effects Of Defendant Race, Psychological Expert Witness Race, And Racially Salient Psychological Expert Testimony On Juror Decision Making, Lily Cheyanne (Manick) Munavu

Dissertations

The present study examined the effects of defendant race, psychological expert witness race, the racial salience of a psychological expert witness's testimony, and modern racism on juror decisions. Participants were randomly assigned to one of eight conditions that varied the race of the defendant (Black or White), the race of the psychological expert witness (Black or White), and the racial salience of the expert witness testimony (racially relevant or not racially relevant). Participants were asked to review the case documents of a criminal case in which the defendant was charged with battery and robbery. Participants rendered verdicts for both charges, …

A Comparison Of Maintenance-Training Methods For Children Diagnosed With Autism, Nicholas L. Weatherly

Dissertations

The current study evaluated the effects of two different maintenance-training methods and one control condition on skill maintenance within a public-school classroom for children diagnosed with autism. The two training methods involved the use of either a continuous-reinforcement schedule or a thinned partial-reinforcement schedule during 20 overlearning training sessions following skill acquisition. The control condition did not involve any overlearning following skill acquisition. Three children were each taught two curricular programs, with each program involving the two training methods and the control condition using a multielement design. Overlearning using a thinned partial-reinforcement schedule reliably produced greater maintenance across all participants, …

Exploring The Cognitive Underpinnings Of Word Retrieval Deficits In Dyslexia Using The Tip-Of-The-Tongue Paradigm, Sarah Margaret Hanly

Dissertations

Over the past thirty years a consensus has emerged that the word reading difficulties of dyslexic readers stem from deficits in phonological processing. One experimental paradigm that has provided support for this view is the finding that dyslexic readers demonstrate deficits in word retrieval from long term memory on picture naming tasks. Dyslexic readers are able to retrieve fewer words in their receptive vocabularies and are less accurate than normally developing readers. However, the conclusion that dyslexic readers? difficulties in picture naming are the consequence of deficits in phonological processing is inferential. The current study uses the tip-of-the-tongue (TOT) paradigm …

The Role Of Perceived Social Support And Cognitive Processing In Reports Of Personal Growth Following Bereavement, Sean M. Engelkemeyer

Dissertations

The current study tests models of personal growth in bereaved individuals (Hogan & Schmidt, 2002; Tedeschi & Calhoun, 2004) by examining the relationships between types of social support and growth following bereavement, as well as by assessing whether deliberate/reflective or automatic/intrusive cognitive processing of the loss mediates the relationship between social support and growth in sample of bereaved adults. A sample of 114 participants who had experienced the death of an immediate family member (spouse, child, parent, or sibling) within the past three years completed a series of self-report measures received by mail. Hypotheses that perceived emotional and advice/ guidance …

Sex Offender Assessment: Clinical Utility And Predictive Validity, Kristopher Lueron Clounch

Dissertations

The research addressing sex offender assessment and treatment is an ever-evolving science. However, very little research has addressed psychological typologies associated with various types of sex offenders and treatment engagement. The current study examined assessment data of four sex offender groups, defined by victim type, to determine if a typological difference exists between groups of (N = 583) rapists (n = 129), statutory offenders (n = 140), intrafamilial/ incest perpetrators (n = 152), and extrafamilial (n = 162). Secondly, the study determined if a specific battery of psychological measures can predict treatment completion (n = 377). We also hypothesized there …

Relation Of Family Functioning To Treatment Outcomes In Day And Residential Programs: A Clinical Study With Emotionally Disturbed Adolescents, Utpala Shanker

Dissertations

Residential and day facilities are important providers of treatment for seriously emotionally disturbed adolescents. The primary difference between the two types of treatment programs is that adolescents attending day treatment reside with their families while those in residential programs live at the treatment facility. Very few studies have addressed the relation of family functioning to treatment outcomes for adolescents. Furthermore, extant research has not investigated whether the relation of family functioning to treatment outcomes is different for adolescents in residential and day programs, This study proposed that adolescents from severely dysfunctional families at admission would have better outcomes in their …

The Stress Process Model And In-Home Respite For Caregivers Of Cognitively And Physically Impaired Older Adults, Lauren Clair Mensie

Dissertations

Common problems in the family caregiving respite outcome literature include little attention to in-home respite, lack of theoretical grounding, and low rates of respite utilization. This dissertation study utilized the predominant model of family caregiving stress, the Stress Process Model (Aneshensel et al., 1995; Pearlin et al., 1990), to (1) investigate the variables through which in-home respite impacts caregivers and to (2) investigate the factors that predict utilization of respite services. Participants (N = 74) were family caregivers receiving federally subsidized in-home respite. Results indicate that both prior hours of in-home respite services and respite time devoted to non-care related …

The Detection Of Malingering On Measures Of Competency To Stand Trial: A Study Of Coached And Uncoached Simulators, Rachael Elizabeth Springman

Dissertations

Competency to stand trial evaluations serve as the most frequently requested type of forensic evaluation. Despite the court?s need for accurate and credible information, defendants referred for competency evaluations may be motivated to malinger incompetency in order to avoid trial and gain personal liberty (Rogers, Sewell, Grandjean, & Vitacco, 2002). Furthermore, motivated malingerers can obtain information about tests prior to evaluations, particularly from the Internet and their attorneys. Previous research has demonstrated that coaching on test-taking strategies helps malingerers avoid detection on psychological tests like the MMPI-2 (e.g., Storm & Graham, 2000), but no research has examined the effects of …

Self-Solicited Feedback: Effects Of Hourly Pay And Individual Monetary Incentive Pay, Julie M. Slowiak

Dissertations

The frequency of feedback solicitation under hourly pay and individual monetary incentive pay conditions was examined. A two-group between-subjects design was used with 30 college students in each group. Participants attended three experimental sessions and entered the cash value of simulated bank checks presented on a computer screen. Results indicated that (a) participants who were paid individual monetary incentives did not self-solicit feedback more often than those who were paid an hourly wage, (b) feedback solicitation was not related to individual differences in levels of competition with one's self or competition with others, (c) task performance was higher for individuals …

Mindfulness In Childbirth: An Investigation Of The Effects Of Mindfulness Training On Maternal Satisfaction With Childbirth And Obstetric Outcomes, Brenda L. Bratton

Dissertations

This study investigated the effects of mindfulness training on obstetric outcomes and maternal satisfaction with childbirth. We were interested in whether mindfulness training was more effective than a control group receiving psychoeducation on stress reduction. The goal of the intervention group was to increase participants' moment-to-moment awareness of thoughts, feelings, and body sensations during childbirth so that they would respond to these experiences rather than react to them in an automatic manner. These strategies were hypothesized to help a laboring woman minimize fear or anxiety associated with pain and complications and be more adaptive to whatever circumstances arose. Repeated measures …

A Comparison Of Three Training Methods On The Acquisition And Retention Of Automotive Product Knowledge, Rhiannon M. Fante

Dissertations

The purpose of this study was to compare the effects of a traditional (non-fluency) web-based training program with and without study objectives with a web-based fluency-building training program on the acquisition and retention of automotive product knowledge. The effects of the training conditions were assessed by how accurately and quickly participants responded on a product knowledge test immediately after training, four weeks after training, and eight weeks after training. A three-group between subjects design was used with 20 college students in each group. Results indicated that participants in the fluency training group were more accurate and fluent immediately after training, …

A Qualitative Study Of Buddhist Informed Psychotherapists, Michael Sean Harris

Dissertations

The field of psychology has a history of distancing itself, if not outright dismissing, both religion and spirituality. In recent years, however, psychology has come to move more toward an embrace of religious and spiritual experience. Buddhism, often expressed as a philosophical system without regard to theistic or nontheistic underpinnings, has been integrated with psychological theory in recent scholarly literature. This dissertation is an exploratory study regarding howBuddhist psychological perspectives are applied in actual psychotherapeutic practice. A participant pool of ten psychotherapists who self-identified as utilizing Buddhism in their work was studied along a variety of dimensions. Demographic questionnaires, audiotaped …

Disruptive Effects Of Aβ Oligomers To The Radial-Arm Maze Performance Of Rats, Kineta Lynn Morgan-Paisley

Dissertations

Converging lines of research have implicated a causal relationship between oligomers of amyloid-β and the cognitive impairments associated with Alzheimer's disease (AD); however, very few studies have provided direct experimental evidence of this relationship and none of those studies have used an established model of working memory. The present study used an established model of working memory, the radial-arm maze, to examine the effects of amyloid-β oligomers on the memory of two groups of rats. The experimental group received ICV injections of the culture media (CM) of Chinese Hamster Ovary (CHO) cells transfected with a human mutation of APP containing …

Defining Acquaintance Rape: College Students' Perceptions Of Sexual Consent And Coercion, Sara Elizabeth Buck Doude

Dissertations

Perceptions of rape have evolved dramatically over the past decade. Prior to the second wave of the feminist movement, rape was perceived to be committed by a psychotic man against a woman. The feminist movement brought the term "acquaintance rape" into the popular lexicon and into the forefront of women's consciousness. As a result, throughout the 1970s and 1980s state governments enacted laws to prohibit "sexual assault," or expanded existing rape laws to include a variety of relationships or sexual acts. However, public perceptions of rape did not evolve as rapidly. Despite legislative efforts, there is no universally understood definition …

Future Psychologists' Perceptions Of Managed Care, Michele Renae Boyer Blood

Dissertations

This study was designed to examine future psychologists' perceptions of managed care, as well as their managed care related training and work experience. Data for this project were gathered electronically via a specially designed website. Participants were 119 future psychologists completing predoctoral internships in university counseling centers (n = 61) and hospitals (n = 58). Variables examined included predoctoral interns' attitudes towards managed care and their perceptions of the importance of knowledge in three critical domains relevant to service provision in the contemporary marketplace (i.e., general reimbursement, risk management, misdiagnosis). One measure, the Demographic and Practice Information Form (DAPIF), was …

The Influence Of Species And Context On Human-Dolphin Interactions, Deirdre Breen Yeater

Dissertations

Anthropogenic activities pose a threat to marine mammals around the world. Cetaceans that use coastal waters are at particular risk for potential disturbances caused by vessel traffic and human swimmers. Although many cetacean species are found near the coast of Utila, Honduras, little is known about their behavior or the effects of anthropogenic activities on their behavior. Whether the presence of boats and human swimmers led to short-term changes in dolphin behavior was investigated for three commonly sighted species of dolphins; rough-toothed (Steno bredanensis), spinner (Stenalla longirostris), and bottlenose (Turslops truncatus). The dolphins' behavioral activities, with and without other boats …

Supervision Experiences And Needs Of New-Entrant Professional School Counselors: A Qualitative Study, Shawn Allan Allan Bultsma

Dissertations

Although the field of professional school counseling has recognized the positive impact that supervision offers, discussion of its use with new-entrant school counseling professionals has been limited. This study responds to the limited discussion of supervision with new-entrant professional school counselors by describing the supervision experiences and perceived needs of 15 new-entrant professional school counselors.

Participants of this study described advantages and disadvantages of receiving supervision. When discussing supervision activities as new-entrant professionals, participants frequently confused the process of supervision with mentoring and evaluation. Supervision quality was described as deficient, and the structure of supervision varied among participants. Participants described …

Pre-Employment Knowledge: Measurement And Relationship To Recruitment Methods And Previous Job And Organizational Exposure, Nancy Kathleen Frye

Dissertations

This study investigated pre-employment knowledge in relation to recruitment methods, job exposure, and organization exposure. In addition, this study investigated a new approach to the measurement of pre-employment knowledge. Specifically, it utilized an agreement approach to measurement (i.e., applicants' responses were compared to job incumbents?) and examined pre-employment knowledge in terms of three subcategories: job, people, and organizational knowledge. Participants completed a questionnaire when they applied for the job. The questionnaire contained measures of recruitment methods, job exposure, and organization exposure, and the three types of pre-employment knowledge. Some support was found for the hypothesis that applicants who used an …

Treatment Of Co-Morbid Methamphetamine Substance Abuse And Borderline Personality Disorder Features Using Modified Dialectical Behavior Therapy, Jessica R. Schultz Fischer

Dissertations

The study investigated the effectiveness of a time-limited, skills-based treatment in a population of female substance abusers. This project implemented a pilot clinical trial to evaluate the effectiveness of a 12-session modified Dialectical Behavior Therapy (DBT) protocol among a small sample of women, with co-morbid borderline personality disorder features, receiving concurrent outpatient treatment for methamphetamine abuse. A non-concurrent multiple baseline design was used. In addition to on-going assessment conducted during baseline and weekly over the course of treatment, a comprehensive assessment battery was administered pre-, and post-treatment as well as at 1 and 3 months following treatment. Findings suggest that …

The Effects Of Acute Nicotine Abstinence On Vigilance And Verbal Memory In Non-Diagnosed Smokers, David W. Ayer

Dissertations

Research has shown a differential prevalence of smoking in the schizophrenic population compared to other psychiatric and non-diagnosed populations. The three most commonly investigated reasons for this differential prevalence in schizophrenics are: the self-medication hypothesis, side effects hypothesis, and sociological hypothesis. The self-medication hypothesis which proposes that schizophrenics smoke at a higher rate to ameliorate cognitive deficits is the most substantiated by the research. Of current interest is the possible role of nicotine in improving performance on vigilance and verbal memory, the two areas shown to be most related to impaired social functioning in schizophrenics. It is difficult to make …

Therapists' Handling Of Secrets Between Partners In Couple Therapy, Michael Alan Jansen

Dissertations

This study examines couple therapists' policies, procedures, and perspectives regarding secrets between partners in couple therapy. Handling secrets appropriately is necessary to avoid legal, ethical and therapeutic problems, especially when the secret involves contentious or potentially dangerous material such as infidelity, divorce, paternity, and HIV/AIDS infection. One hundred sixty randomly selected Clinical Members of the AAMFT participated in a 38-question researcher-generated mail survey. Data provided descriptive statistics and allowed for between-groups comparisons to explore for differences between therapists with regard to experience and several specific practices related to handling secrets. The study also examined whether courses in HIV/AIDS confidentiality law …

An Investigation Of Relationship Characteristics, Exercise And Physical Activity, Couple And Life Satisfaction, Mark W. St. Martin

Dissertations

Exercise has been shown to be positively related to many different variables including sexual satisfaction, mental health, and physical health. These variables, in turn, have been linked to increased life satisfaction and couple satisfaction. The primary purpose of this study was to examine the relationships between exercise and couple satisfaction as well as exercise and life satisfaction. A secondary purpose was to replicate previous findings on the relationships between communication, love, sexual satisfaction, self-esteem, and physical health and couple satisfaction.

A total of 229 undergraduate and graduate students from a large Midwestern university in the United States participated in this …

A Study Of Intake And Assessment In Solution-Focused Brief Therapy, Christopher J. Richmond

Dissertations

The purpose of this study was to compare clients' assessment of two different counseling intake procedures used by clinicians. This study compared a Solution-Focused Brief Therapy (SFBT) intake intervention with an intake intervention constructed from the Structured Clinical Interview for the DSM-IV Axis I Disorders (SCID-I). The SCID-I is one of the most widely used diagnostic interviews and reflects a "gold standard" in formulating accurate diagnoses. The SFBTintake intervention developed for this study stands in stark contrast to the SCID-I and its primary objective, evaluation of the problem. SFBT is a strength-based model that maintains a positive and future-oriented focus. …

Behavioral, Attitudinal, And Decision-Altering Effects Of Aggressive Video Games On Young Adults, Kent Smallwood

Dissertations

Each year, interactive video game technology becomes more and more advanced, offering more lifelike environments, immersive experiences, and realistic situations in which the player must decide how to act. As a result of these technological advancements, the violent content in video games has become increasingly realistic and graphic. Unlike the passive viewing experience of television, video game players adopt roles in which they initiate actions and direct the progression of video game experience. In these active roles, they may engage in and be rewarded for violent acts against fictitious video game characters or other online players. Furthermore, the videogame industry …

A Qualitative Exploration Of First-Generation Asian Indian Women In Cross-Cultural Marriages, Monica Thiagarajan

Dissertations

The literature on Asian Indian women has not adequately addressed the experiences that first generation Asian Indian women face while going through the process of making the decision to marry cross-culturally. The purpose of this exploratory study was to identify, describe, and understand the struggles, challenges, and conflict experienced by Asian Indian women who decide to marry cross-culturally and to understand the consequences of the decision on the lives of these women and their interpersonal relationships.

Initial and follow-up phone interviews were conducted with eight Asian Indian women who had experienced cultural and familial challenges regarding their decision to marry …

The Role Of Communication Channel, Feedback Valence And Cultural Differences In Performance Appraisal Outcomes, James C. Matchen

Dissertations

The effects of feedback valence (positive or negative) across culture (Individualistic or Collectivistic) for both the verbal and nonverbal communication channels on performance appraisal outcomes were investigated. It was hypothesized that participants would react differently to the performance appraisal they received based on (1) their own cultural values and on (2) the valence of the verbal feedback and nonverbal feedback provided by the manager. Main effects of both verbal feedback valence and nonverbal feedback valence were predicted and found. Participants reported more positive reactions to both the performance appraisal process and to the manager after receiving positive feedback than after …
