Discriminative Stimulus Effects Of (+)-7-Oh-Dpat In Rats: Importance Of D3 Receptors, April J. Christian

Masters Theses

Despite the reported relatively high binding affinity of 7-OH-DPAT to dopamine D₃ receptors, results of recent investigations with the highly selective 03 receptor antagonist, PNU-99194A have questioned the importance of 03 receptors in the discriminative stimulus effects of 7-OH-DPAT. In the present study, sixteen male Sprague- Dawley rats (N=8/group) were trained to discriminate (+)- 7-OH-DPAT (0.03 mg/kg, sc) from saline in a two-lever operant procedure using a fixed-ratio 20 schedule of water reinforcement. After stable performance was established, substitution tests were conducted with the D₃-prefering agonist, (+)-PD-128907 and the psychostimulant cocaine. Additionally, antagonism were conducted with the …

The Biphobia Scale: Development And Validation, Patrick S. Mulick

Masters Theses

Sexual orientation is generally assessed as a dichotomous variable, rather than a continuous variable. According to this classification the concept of bisexuality does not exist and there is a dearth of research for the construct. Some theorists believe that this lack of knowledge has led to fear and discrimination of bisexual individuals (Ochs, 1996; Rust, 1993). Biphobia, defined as negative attitudes about bisexuality and bisexual individuals, is a psychological construct that is not well understood. There has been a recent resurgence of interest in bisexuality and biphobia but there are currently limited empirical investigations examining the constructs. And, no scale …

Behavior-Based Safety And Working Alone: The Effects Of Self-Monitoring On The Safe Performance Of Bus Operators, Ryan Olson

Masters Theses

Experimental evaluations of Behavior-based Safety (BBS) processes applied with lone workers are scarce. Further research is needed to determine the power of self-monitoring based interventions for improving safe behavior, and to explore the best practices for improving safety when employees work alone. In the current study,· four male bus operators (ages 40-50) self-monitored their safe performance and initialed feedback graphs based on their self-monitoring data at the end of each day. Experimental data collectors observed each participant by riding buses as passengers. A multiple baseline design across performances was used to assess the effects of the intervention on four target …

Exploring Thematic Balance In Personal Narrative As A Marker For Responsiveness, Laura G. Porter

Masters Theses

Research on personal narrative as a template or map that organizes experience and creates a lens for the interpretation of reality has largely relied on structural analysis for its assessments of adequacy. As a synthesis of beliefs and values with actions, thoughts, and feelings, however, the tone and thematic quality of an individual's life story must also shape the narrative compass that guides interactions in the social world. Among these elements, one's theory of reality will exert a significant impact on the overall context within which the specific unfolding of narrative plots occurs. In Western societies in particular, this perspective …

Effects Of Methylphenidate On The Sensitivity To Reinforcement In Children Diagnosed With Adhd: An Application Of Matching Law, Laura Kay Murray

Masters Theses

This experiment evaluated the effects of methylphenidate on sensitivity to reinforcement of children diagnosed with ADHD using matching law.

Four children (2 males and 2 females) between the ages of 6 and 10 who were previously diagnosed with ADHD completed easy math problems to earn tokens under four different variable-interval (VI) schedules of reinforcement presented in random order. The rate of completed math problems was plotted against the mean frequency of obtained reinforcers at each schedule value in tokens per minute. The data were fit to the following single-rate hyperbolic equation (Herrnstein, 1970): R = kr/r+r₀.

Results show …

A Three-Choice Drug Discrimination Procedure Differentiates The Stimulus Effects Of D-Amphetamine And Mdma, Amy K. Goodwin

Masters Theses

(±)-3,4-Methylenedioxymethamphetamine (MDMA) produces effects in humans that are reportedly similar to those of CNS stimulants. However, drug discrimination studies in nonhumans have yielded inconsistent results regarding the similarities between MDMA and d-amphetamine. Sixteen male Sprague-Dawley rats were trained to discriminate d-amphetamine, MDMA, and saline in a three-lever drug discrimination procedure. In addition, differential outcomes were employed during drug discrimination training with eight of the rats but this did not appear to facilitate the acquisition of the discrimination. Cocaine (0.25-10.0 mg/kg) produced dose dependent increases in d-amphetamine-appropriate responding with complete substitution at the highest dose administered. LSD (0.02-0.16 mg/kg), produced dose …

Application Of Differential Outcomes To A Cocaine-Saline Discrimination Procedure: Assessment Of Stimulus Generalization To Dopamine D3 Receptor Agonists, Kelly J. Garner

Masters Theses

This study replicated the effects of differential outcomes on the acquisition of a cocaine-saline discrimination in rats and examined whether learning via differential outcomes (DO) influenced stimulus generalization to other drugs. Previous investigations have suggested that the dopamine (DA) D3 receptor subtype may modulate the reinforcing effects of cocaine. Pharmacological compounds which have been identified as having a greater affinity for DA D3 receptors are 7-OH-DPAT and PD 128907. The present study examined whether the DO conditions applied during training had an impact on the generalization of these test compounds. Two groups of male Sprague-Dawley rats were trained to discriminate …

Conditional Discrimination And Generalization Of Facial Cues As A Function Of Training Multiple Exemplars With Autistic Preschoolers, Sebastien Bosch

Masters Theses

Individuals with diagnosed autism typically show deficiencies in discrimination of facial cues. The ability to respond to facial expressions was assessed and trained with 3 four-year-old subjects diagnosed with autism. Stimulus presentations involved four different stimulus sets ( cards with stick figure, cards with cartoon figures, and cards with photographs of a man and a woman displaying the emotional expression).

Training consisted of differential reinforcement of correct responses. The experimental design was a multiple baseline across stimulus sets, with generalization probes conducted after mastery level of performance was reached on each stimulus set. Some evidence of generalization was observed on …

An Investigation Of The Construct Validity Of The Children's Skills Test, Cynthia D. L. Ladd

It is designed for home administration via the computer, and no examiner is present. At this time, no technical information has been released regarding the CST, nor has any research been published.

The Kaufman Brief Intelligence Test (K-BIT) is a brief measure of general intelligence with sound technical properties. It is administered by an examiner. The K-BIT has been correlated with the Wechsler Intelligence Scale for Children, Third Edition (WISC-III), the most commonly …

An Investigation Of Convergent And Divergent Validity Between Asca And Basc Trs, Jennifer L. Ingles

Masters Theses

The Behavior Assessment Scale for Children - Teacher Rating Scale (BASC - TRS) and the Adjustment Scales for Children and Adolescents (ASCA) are both teacher rating scales which may be used by school psychologists to assess psychopathology. To date, these scales have not been compared in professional literature, although they assess similar social, emotional, and behavioral constructs. According to research, both scales appear to be technically superior teacher report rating scales. The current study analyzed ASCA and BASC TRS ratings which were completed on randomly selected students between the ages of 6 and 11 (n = 124). Convergent validity was …

A Study Of The Relationship Between Personality Type And Emotional Response To Athletic Injury, Jasmin C. R. Hutchinson

Masters Theses

This investigation was designed to examine emotional response to athletic injury using personality constructs within reversal theory. Twenty-five (male = 19, female = 6) collegiate athletes, ranging in age from 18 to 22 years (mean = 19.95, SD = 1.11) who sustained a minimal criteria injury during a six-week data collection period participated in this study. Each athlete's total mood disturbance (TMD) was measured pre-injury and post-injury using the Profile of Mood States (POMS). Athlete's personality orientation was measured using the Paratelic Dominance Scale (PDS). A dependent t-test indicated a significant increase in TMD scores following injury (p < 0.05), thus indicating overall mood disturbance in injured athletes. An independent t-test comparing paratelic and telic dominant athletes on TMD difference scores revealed non-significant results (p = 0.40). Methodological and theoretical reasons for this are examined and implications for further study of reversal theory and athletic injury are discussed.

Attachment Styles And Childhood Trauma In Batterer Subtypes, Eric S. Davidson

Masters Theses

Eighty-three men seeking treatment for domestic violence and 28 non-violent control subjects completed self-report questionnaires on conflict resolution, attachment styles, and childhood trauma. Those seeking treatment were divided into three batterer subtypes in order to determine if there were differences between the three groups and the control group in attachment styles, and childhood trauma (overall trauma, sexual assault, punishment, and neglect). There were no significant relationships found between batterer subtype or subject status (batterer vs. non-batterer) concerning attachment style. Significant results were found concerning trauma and batterer status, as well as some significant differences between batterer subtype and trauma. Limitations …

The Construct Validity Of The Adjustment Scales For Children And Adolescents (Asca) And The Preschool And Kindergarten Behavior Scales (Pkbs), Jamie D. Rich

Masters Theses

The Adjustment Scales for Children and Adolescents (ASCA) and the Preschool and Kindergarten Behavior Scales (PKBS) are two relatively new behavior assessment scales that measure youth problem behavior. The ASCA is designed to be completed by the child's classroom teacher. The PKBS is designed to be completed by the child's teacher, parent, or day care provider. Both scales are unique and are considered to be technically adequate. Many of their syndromes/subscales and global scales/composites are similar in nature and description according to their respective manuals. No research, however, has been conducted establishing convergent evidence of construct validity between these two …

Is Achievement Motivation In Basketball Games Affected By Team Or Individual Competitive Situations In Elementary Physical Education Classes?, Adam C. Lane

Masters Theses

This study examined the relationship between skill, setting and gender. There were three main purposes for conducting this study. The first was to determine whether a child's achievement motivation changes when participating in a team setting compared to an individual setting. The second purpose was to determine and compare any differences between boys' and girls' achievement motivation, in both team and individual settings, and thirdly, to determine and compare any differences between the achievement motivation of high-skilled and low-skilled children, in both team and individual settings. Subjects were administered the Sport Orientation Questionnaire, (Gill and Deeter, 1988), which assesses competitiveness, …

Health Locus Of Control, Perceived Health Competence, And Fluid Adherence In Hemodialysis Patients, Mark W. Conard

Masters Theses

Patient adherence with prescribed medical regimens is vital in promoting the health of patients. Complex medical regimens are difficult for patients to follow and it is therefore important to understand what causes patients not to follow their prescribed treatment recommendations. Hemodialysis (HD) is one such complex medical regimen that requires patients to follow strict restrictions in their diet. One area of the HD regimen that is particularly hard for patients to adhere to is restrictions in the amount of fluid they can safely consume. Research has shown that noncompliance to fluid restrictions is pervasive, with patients stating that adherence to …

Perceived Social Support And Exercise Compliance Of Phase Iii Patients In Cardiac Rehabilitation Programs, Rana M. Smith

Masters Theses

The purpose of this study was to determine if there was a difference in the level of perceived social support from family, friends, and program staff in Phase III patients who comply and patients who do not comply to cardiac rehabilitation programs.

Staff of 22 cardiac rehabilitation programs in ten different states, distributed 10 surveys to compliers and 10 surveys to non-compliers. A three-part questionnaire was designed to gather information regarding demographics, perceived staff social support and perceived family social support. Independent t-tests were used to determine if there were differences in perceived social support between compliers and non-compliers.

Effects Of Interparental Conflict Tactic Styles On The Psychological Adjustment Of College Undergraduates, Jodell D. Bauer

Masters Theses

Past research has examined the effect of the level of interparental conflict on the psychological adjustment of children and young adult offspring. Research has suggested that higher levels of conflict in intact, separated, and divorced homes have negative effects on the psychological adjustment of children and young adults. Recent studies have further examined interparental conflict by examining the styles with which parents resolve or cope with conflict and it's effect on their children. This study assessed the effect of different interparental conflict styles of mother and of father on college-age offspring. The three styles examined were negotiation, psychological aggression and …

The Status Of Workplace Violence In The United States: A Model For Prevention And Intervention, Linda Meliza Moore

A comprehensive review of existing literature is presented and a new model for prevention and intervention of workplace violence is proposed for use by practitioners. Suggestions for further data collection and research are presented so that further refinement can be made to workplace violence prevention and intervention models.

A Comparison Of The Social Skills Rating System And The Preschool And Kindergarten Behavior Scales, Susan Hayner

Masters Theses

The Preschool and Kindergarten Behavior Scales (PKBS) and the Social Skills Rating System (SSRS), Teacher Form, at the Preschool and Elementary Levels, are fairly new instruments that purport to evaluate children's prosocial abilities and deviant problem behavior. Little research exists comparing the two instruments. Both scales have been determined to be globally technically adequate. However, the research has been limited thus far. The purpose of the current research was to further investigate the relationship between the two scales. A sample of children (n=136) in west central Illinois public and private preschools were used to collect the data. Of these, 64 …

The Reliability And Validity Of The Children's Conscientiousness And Procrastination Scale, Nicole M. Osterman

Masters Theses

The purpose of the present study was to further examine the reliability and validity of a self-report measure of procrastination and conscientiousness for elementary-aged children. The research participants were 120 male and female students in grades 3-5, drawn from two different schools. The Children's Conscientiousness and Procrastination Scales (CCAPS; Lay, Kovacs, & Danto, 1998) exhibited high internal consistencies. Procrastination and Conscientiousness were highly, negatively related, consistent with previous research with related measures and with adult samples. Teacher and parent ratings of students were moderately correlated with the student's self-reports, thereby providing support for the convergent validity of the self-report measure. …

The Use Of Noncontingent Reinforcement In The Regular Education Classroom With Attention-Deficit Hyperactivity Disorder Children, Heather A. D. Ochs

Masters Theses

A problem that exists in many regular education classrooms is excessive disruptive behavior of students. This study will examine the disruptive behavior of two children, age 8, who have been diagnosed with Attention-Deficit Hyperactivity Disorder, in a simulated regular education classroom. Due to a renewed emphasis on linking treatment to functional analysis, noncontingent reinforcement was utilized to determine whether teacher mediated or peer mediated attention can decrease the disruptive behavior. This study used a multi-element design for the functional analysis and a reversal (ABAB) design to evaluate the effects of the noncontingent reinforcement treatment. Results indicated that peer attention was …

Grade Equivalents: Accuracy And Certainty Of Interpretations Among Parents, Teachers, And School Psychologists, Eric R. Smith

Masters Theses

Scores on standardized tests (e.g., Iowa Test of Basic Skills, Wechsler Intelligence Scale for Children III, Wechsler Individual Achievement Test) can be represented by a number of different metrics. One of the ways scores can be represented is with grade equivalents, which tend to be popular with parents and teachers because they seem to be fairly easy to understand. However, several researchers have claimed that grade equivalents are often misinterpreted. Standard scores are viewed by many researchers as the superior type of derived score. However, standardized scores can be difficult to understand, particularly for individuals with little or no training …

Collaborative Versus Prescriptive School-Based Behavioral Consultation: An Analysis Of Verbal Resistance, Brandon M. Royer

Masters Theses

Audiotaped problem analysis interviews involving actual referrals from 25 elementary school teachers were examined. A Teacher Resistance Code (TRC) was developed from Patterson's (1985) Client Noncompliance Code and used to evaluate verbal resistance in both "collaborative" and "prescriptive" problem analysis interviews. The relationship between resistance, interview condition, and treatment acceptability was assessed. Results indicated no significant differences in resistance between the collaborative and prescriptive conditions. Analysis of Intervention Rating Profile-15 (IRP-15) (Martens, Witt, Elliott, & Darveaux, 1985) scores between collaborative and prescriptive cases also revealed no significant differences. Analysis of the association between resistance on the Teacher Resistance Code and …

The Relationship Between Family Environment And Proneness To Shame And Guilt, Ericka N. Hamilton

Masters Theses

This study examines shame- and guilt-proneness and family environment factors that predict these two affective experiences. One-hundred and ninety undergraduates completed the Test of Self-Conscious Affect and the Family Environment Scale. The results indicated that a family emphasis on moral and religious issues and values was most predictive of shame. An emphasis on moral and religious issues and values as well as an interest in social and political activities was most predictive of guilt. The findings in this study differ from the theoretical literature which has suggested that the relationship between family environment and an individual's proneness to guilt and …
