Differences In Values And Goals Of Occupational Therapy Students, Margaret A. Danka

Masters Theses

This study compared professional values and goals of three levels of occupational therapy students: (1) seniors in baccalaureate programs (n = 337), (2) students in professional master's programs (n = 95), and (3) students in post-professional master's programs (n = 62). Demographic characteristics and factors influencing career choice were also examined.

Significant differences were found among the three student groups for three professional goals: (1) contributing to theory, (2) doing research, and (3) educating occupational therapy students, and four professional values: (1) intellectual stimulation, (2) exciting life, (3) comfortable life, and (4) helpfulness. The demographic differences among the three student …

Applying The Matching Law In A Sheltered Workshop, Kristin Elizabeth Skousgard

Masters Theses

This study assessed the validity of the matching law in an applied setting. It manipulated extraneous reinforcement and measured the rate of rocking in a 24-year-old developmentally disabled man. The resulting data were compared to that predicted by the matching law.

The results were important in three ways: (1) extraneous reinforcement systematically affected rocking in an applied setting in the manner predicted by the matching law, (2) a clinically undesirable behavior decreased in frequency, and (3) this decrease occurred in the absence of direct intervention on the target behavior. Thus, to a slight degree, scientific, practical and humanitarian goals were …

Standing Time While Engaged In An Upper Extremity Activity Versus Standing Time While Not Engaged In An Upper Extremity Activity, Wendy A. Smith

Masters Theses

The standing time of recent (within four weeks) cerebral vascular accident subjects while engaged in an upper extremity activity (tile trivet) was compared to the same subjects standing time while not engaged in an upper extremity activity. The subjects from a rehabilitation center ranged in age from 30 to 85 years. For each subject three sessions were randomly recorded for each condition. Lights were connected to the knee and buttock pad so that, if activated, they alerted the data collector that the subject was leaning.

The findings from this study indicated that subjects stood longer while engaged in upper extremity …

Solitary Aerobic Exercise As A Treatment Of Unipolar Depressive Disorders In Women, Lisa Ann Romano-Neal

Masters Theses

The effects of solitary aerobic exercise on depressive symptoms were tested on four women diagnosed with unipolar depressive disorders. A multiple baseline design was employed. The subjects individually participated in uniform one hour aerobic workouts three times a week for five to eight weeks. Heart rate measures were monitored through the utilization of the physical working capacity test with the Monark 818E Professional Ergometer. Predicted volume oxygen uptake (VO2 max) measures at post-treatment did not increase in two of the four subjects when compared to pre-treatment VO2 max measures. The mean percentage of depressed adjectives endorsed showed minimal reductions on …

The Effects Of Problem-Solving Skills Training With Chronic Schizophrenic Patients, Asiah Mayang

Masters Theses

Problem-solving skills were taught to aggressive and frequently secluded chronic schizophrenic inpatients of a psychiatric hospital. A pre-intervention/post-intervention experimental-control group design was utilized. Eighteen patients were randomly assigned to three groups: six were assigned to the “treatment group” and received problem-solving skills training involving instructions, modeling, feedback, role-playing and social reinforcement; six were assigned to the “interaction” group, involving social interactions with the trainer only; and six were assigned to the “control” group, involving no treatment or interaction with the trainer. Improved problem-solving skills on both familiar and novel video-taped skits were observed for the treatment group, but not for …

Effect Of Therapist-Initiated Versus Self-Initiated Vestibular Stimulation On Vocalization In Children With Autism, Carol L. Maddox

Masters Theses

Therapist-initiated vestibular stimulation was compared to self-initiated stimulation to determine their relative effects on vocalization in children with autism. Vocalizations produced during table-top activities were also compared to those produced during vestibular stimulation. Two children with autism participated in the study. Vestibular stimulation was provided by a hammock swing. All vocalizations were recorded during a total of thirteen 15-minute test sessions.

Results indicated that in this study: (a) There was no significant difference in quantity of vocalizations produced during self-initiated versus therapist-initiated vestibular stimulation, and (b) there was a significant increase in vocalizations during vestibular stimulation as compared to during …

An Investigation Of Three Strategies To Enhance Generalization Of Conversational Skills, Janice Ann Cain

Masters Theses

The purpose of the present study was to investigate the effects of three strategies to enhance generalization of taught conversational skills: (1) multiple and varied scenarios, (2) multiple conversational partners, and (3) homework assignments. A multiple baseline across behaviors design tested whether the initial training package produced generalization to the probe sessions and whether the addition of homework would produce greater generalization to the probe sessions compared to that observed during the initial training. Four adults, one male and three female, ranging in age from 20-64 years served as subjects. Skills were taught using a combination of coaching, modeling, behavioral …

Behaviors o f self-recording by staff and instructions and goal setting by the unit supervisor were targeted. Feedback was provided by the unit supervisor in the form of publicly posted graphs indicating percent of completed assigned activities. The four phases used in the data summary include: (1) baseline, (2) goal …

Progressive Muscle Relaxation As An Adjunctive Treatment For Moderate Asthmatics, Kellye Hutton Slaggert

Masters Theses

This study examined the effects of parent assisted progressive muscle relaxation (PMR) training on moderate asthmatics. Three children between the ages of 7 and 12 participated in the study. After 3 weeks of PMR training and daily practice, the parents became involved in prompting their children to use PMR when an attack appeared likely.

The findings from this study suggest that parental prompting of PMR was instrumental in decreasing the frequency of attacks, increasing peak expiratory flow rates (PEFR) values, and decreasing the severity of attacks for 2 of the 3 subjects. The long term implications for using PMR as …

Comparison Of Behaviors Of Suspected Sexually Abused And Nonsexually Abused Preschool Children Using Anatomical Dolls, Rita Kenyon-Jump

Masters Theses

Using anatomical dolls, the play behaviors of nine sexually abused preschool children (five males, four females), ranging in age from 3-5 years, were compared with nine preschool children with whom there was no suspicion of sexual abuse and who were matched on the basis of age, gender, race, family status, and socioeconomic status. There was no significant difference between the two groups on explicit sexual behavior (vaginal, oral, and anal intercourse with thrusting motions between the dolls or between the child and dolls and masturbation by the child). The groups were significantly (t (8) = 2.19, p < .05 ) different when behaviors with suspicious sexual implication were combined with explicit sexual behaviors. There were no differences between the groups on measures of aggression, anxiety, and nonsexual behavior. The occurrence of the suspicious sexual behaviors is discussed and reviews of previous doll research and physical evidence of child sexual abuse are provided.

Acoustic Characteristics Of Vowels Produced By Men, Women And Children, Laura Arlene Getty

Masters Theses

This investigation was a replication and extension of Peterson and Barney’s (1952) research on the acoustics and perception of vowels. This study explored the acoustic characteristics of 12 vowels produced by 50 men, 50 women and 41 children. Speech samples were tape recorded as subjects read lists of words and isolated vowels. Speech samples were digitized. Speech waveforms, spectrograms and formant frequencies were examined and measured.

The average formant frequency values were similar but not identical to the values reported by Peterson and Barney (1952). The largest discrepancy between the two studies was the degree of overlap among vowel categories, …

Analogical Reasoning Of Elderly Adults Using Three Modalities: Words, Pictures, And Figures, Judy L. Rau

Masters Theses

This study examined the analogical processing skills of elderly adults. Forty-seven subjects (ages 65-90) completed analogy tasks presented in three modalities: words, pictures, and geometric figures (90 total). The subjects for this study were elderly adults living independently in a federally subsidized apartment building. The subjects used in this study possessed characteristics similar to the "typical" American adult. Results indicated that performance does not vary significantly with age in the word and picture modalities. Significant (p < .05) negative relationships were found between performance on the geometric figure analogies and increased age and between overall performance and increased age. Significant (p < .05) positive relationships were found between education and performance on each of the three modalities as well as between education and overall performance.

The Effects Of Aerobic Conditioning Upon The Resting Metabolic Rate, Marti R. Davis

Masters Theses

This study com pared the metabolic rate following an exercise bout to the resting metabolic rate (RM R) established in pretesting procedures for twelve college age females. The only factor differentiating the groups was length o f the training period (one week, two weeks, four weeks, and five weeks). Training took place on a Bosch cycle ergometer three times a week, for 30 minutes each session, at 70 to 85 percent o f the subjects' heart rate reserve (HRR). Breath analysis was measured on a Beckman Metabolic Cart in both pretesting and post-testing procedures.

The findings indicated that aerobic exercise, …

The Effects Of Repeated Trials On The Cardiovascular Responses To Reading Aloud And Non-Stressful Conversation, George S. Renfrey

Masters Theses

This study assessed changes in blood pressure, heart rate, skin conductance, frontalis muscle tension, and breathing rates associated with repeated reading aloud and non-stressful conversation. Four male and 3 female normotensive subjects participated. Sixteen presentations of both verbal tasks, each preceded by a quiet rest period, were made across 8 sessions.

The results indicate that: (a) when compared with resting levels, statistically significant increases in heart rate, blood pressure, skin conductance, and frontalis muscle tension, and decreases in breathing rates may be produced by reading aloud and non-stressful conversation; (b) systolic blood pressure changes attenuate with repeated trials; and (c) …

Perceptual Effects Of Perturbation And Additive Noise, Richard E. Nero

Masters Theses

This study investigated the perceptual effects of varying glottal waveshape perturbation, duty cycle perturbation, jitter, signal-to-noise ratio perturbation, and shimmer at three levels of perceived magnitude (high, medium, and low). Voice signals were synthesized using a modified version of Klatt's (1980) formant synthesizer. Listeners rated signal dysphonia using an A-B dissimilarity procedure. Multidimensional scaling analysis suggested that signals judged low in magnitude of dysphonia were perceived to be most similar. Medium-level and high-level magnitude signals were judged to be respectively less similar. Signals varying in duty cycle and fundamental frequency perturbation were perceived to be very similar while those signals …

Antecedent Aerobic Exercise Training With Schizophrenic Outpatients, Kathlyn A. Fuller

Masters Theses

This research evaluates the effects of aerobic exercise on the symptoms of schizophrenia. The positive and negative symptoms of schizophrenia were repeatedly measured by using direct observation, surveys, and care giver checklists. Symptoms are subcategorized as positive and negative as suggested by Andreasen (1984). Aerobic exercise classes were taught 4 days a week for 6.5 weeks to chronically mentally ill clients in a community based day activity program. Participants were observed 1 hour and 3 hours following the aerobic session. The results demonstrated that chronic individuals exercised at an intensity sufficient to produce an aerobic training effect based on pulse …

Self-Control In Children: The Impact Of Reinforced Commitment, Michael G. Winter

Masters Theses

The present study attempted to determine whether offering a reward to subjects for "commiting" to a large, delayed-reward task affected their degree of self-control as assessed by the "switch point." Two boys and two girls between the ages of three and five participated.

The results of this study indicate that providing a reward for making a commitment to a future behavior involving a large, delayed-reward task does have an effect on a child's degree of self-control as measured by the "switch point." In addition, the "switch point" has been shown to be a useful tool for assessing a child's degree …

Teacher And Student Discourse Variables In Academic Communication, Janet M. Sturm

Masters Theses

This study was designed to analyze the oral communication exchanges between first, third, and fifth grade teachers and their students. It was based on the hypothesis that discourse parameters of linguistic quantity and complexity and communication acts change over grade level, much as the discourse parameters of caregivers with young children have been found to do. The language of teachers and students in 15 classrooms was examined by measuring 6 form and quantity variables and 11 communication act variables. Results showed significant differences for some form variables (MLU, mazes, and Type-token ratio) and some communication acts (convey content, mark content, …

The Effect Of A Multi-Component Treatment Package On Seat Belt Usage Among Hispanics, Senez Rodriguez-Charbonier

Masters Theses

This study analyzed the impact of a combination of approaches on the frequency of seat belt usage in a large Hispanic community in western Michigan. Subjects in either a treatment or a no-treatment control condition were observed weekly for seat belt usage while arriving at church over several months. They were observed for four weeks prior, during and after an intervention program. Subjects in treatment condition attended weekly group meetings where they viewed seat belt use promotion videos, publicly signed behavioral contracts agreeing to use their seat belts, and received permanent prompts which were installed on the dashboard of their …
