This study examines the history and development of vibrato among classical saxophonists as well as briefly summarizes the history of vibrato in general from its origins on string instruments, the voice and other wind instruments. An analysis of recordings of early saxophonists shows the approximate time period of incorporation of vibrato on the saxophone and the influences of performers and musical styles on its development. Pedagogical methods of performing vibrato on the saxophone are included as well as a discussion of saxophone vibrato styles. An exploration of vibrato as an expressive musical device is provided along with conclusions drawn concerning performance practice implications.

The purposes of this study were to determine whether brain growth spurts occur in normal pupils and to determine whether there was a uniform difference in head circumference between boys and girls. Subjects were 3,062 normal elementary pupils, grades one through six, from one suburban school district. Fiberglass measuring tapes were used to measure pupils' head circumference. The hypotheses of the study predicted that the relationship between head circumference and age would be linear. Further, it was predicted that the differences in head circumference between boys and girls would be uniform over seven specified ages. The first hypothesis was tested using a test for linear trend and deviation from linear trend using the General Linear Models procedure. The results indicated that there was a significant linear trend between head circumference and age. The test for deviation from the linear trend was not significant. This would suggest that any deviation from a straight line observed in the data can be attributed to chance. It was concluded that since there was no significant deviation from linear trend, it would suggest a continuous growth of the brain for the ages included in this study. A two-way analysis of variance was used to test …

This study evaluated the role of asymmetric processing of information in depression. Depression has been hypothesized to involve a deficit in the global processing of information (Tucker, 1982). This type of global processing has been manipulated through the use of hypnosis by Crawford and Allen (1983). In the current study, a 3 x 2 ANCOVA design allowed the comparison of three groups of subjects on their performance on a perceptual task measuring global perception. The task chosen was designed by Navon (1977) and consisted of designs which differed on global or local features. The groups were screened with the Beck Depression Inventory, the Harvard Group Scale of Hypnotic Susceptibility, and the Edinburgh Handedness Inventory, yielding 46 subjects divided into three groups of right-handed males and females. The experimental group consisted of high susceptible depressives from the community. The controls were one group of high susceptible normals and one of low susceptible depressives. All groups performed the Navon task under both waking and hypnosis conditions. Analysis of the results revealed a main effect for group (F(2, 86) = 9.60, p < .01) on the global scores. In addition, high social desirability scores predicted slower presentation times. However, hypnosis was not effective …

The Behavioral Medicine Questionnare (BMQ) is a 44- item instrument administered via a computer CRT display or pencil and paper. The BMQ was designed to help primary care physicians treating spinal disorders to screen for emotional factors which warrant further psychological evaluation. The test is composed of three scales: Anxiety, Depression, and Somatization. Concurrent validity for each scale was determined through comparisons with subject (n = 133) scores on clinician judgement ratings, pain drawings, and the MMPI. The psychometric properties of the test were supported through statistical analysis. Significant correlations were found between the BMQ, MMPI, and clinician ratings, with the latter showing relationships of lesser strength. The only significant correlation to subject generated pain drawings was to the BMQ depression scale. Analysis indicated the need for seperate norms for males and females. Further research is needed to facilitate measurement and interpretation of the BMQ.

This study reviewed the literature regarding forgiveness and developed a structured group counseling format with the theme of forgiveness. The purpose of the study was to determine the effect of forgiveness as used in group counseling upon depression, generalized anxiety, dogmatism, relationships, guilt, and forgiveness in the participants. Thirty subjects were selected to participate in one of three groups: an experimental group, a comparison treatment group, and a control group. The experimental group and the comparison treatment group participated in two-hour group sessions, once a week for ten weeks. The experimental group was didactic and experiential with the focus on forgiveness, whereas the comparison treatment group was problem solving using Redecision Therapy. All groups participated in pre and post test sessions. The seven hypotheses in this study were tested with a multivariate analysis of covariance as well as univariate analysis of covariance for each hypothesis. Significance in differences between means was tested at the .05 level of significance.

The purpose of the present study was to determine if psychological stress, defined as academic examination stress, would systematically produce changes in immune parameters (immunoglobulin concentration) and psychological functioning. It was hypothesized that as examination stress occurred there would be an effect on immunological function consistent with heightened psychological activity/stress. Subjects were 23 master's and doctoral students in psychology who volunteered for the research project. All subjects were administered a series of psychological tests to measure stress, personality factors, emotional states, and anxiety levels. All tests were administered and.blood samples drawn over a period of 15 months across two lowstress and two high-stress periods. Immunological tests included white blood cell (WBC) differential count and radial immunodiffusion (RID) for the determination of concentration of different immunoglobulin classes (IgA, IgG, IgM) in serum. Data were treated to a one-way analysis of variance (ANOVA) with repeated measures, t /test for correlated samples correlational matrix between variables across assessments and discriminant function analysis. Results showed (1) increased immunoglobulin levels during periods of stress; (2) immunoglobulin G most consistently related to stress and probably most indicative of the stressed condition and biological resistance to stress; (3) anxiety related to external events; (4) increase in anxiety …

Abuse in adult relationships as affected by stress, anxiety-proneness, and exposure to abuse as a child was examined using 579 North Texas State University undergraduates, Frequency and levels of abuse observed or received as a child and received or expressed as an adult were measured using a modification of Straus' Conflicts Tactics Scale (1979). Anxiety-proneness was determined by scores received on Spielberger's (1970) State-Trait Anxiety Inventory. Current levels of stress for the past two years were measured using the Life Experiences Survey (Sarason, 1978). Overall frequencies for received and expressed abuse (including physical and verbal abuse) in adult relationships were quite high (62.9 percent and 73.8 percent respectively). Females reported expressing significantly more abuse than did males. No gender differences were found for the receipt of abuse. Gender differences in types of violence were also examined. In addition, multiple regression was used to determine predictor variables for the expression and receipt of abuse. For males, receiving abuse as a child, positive stress scores, higher levels of anxiety-proneness, and observing father's abuse of mother significantly predicted expressing abuse as an adult. Observing mother's abuse of father and positive stress scores significantly predicted receiving abuse as an adult. For females, having received …

High performance liquid chromatography was used to measure ribonucleoside triphosphates in microbial samples. Anion exchange columns in a radial compression module were used to separate and quantify purine and pyrimidine ribonucleotides. Endogenous ribonucleoside triphosphates were extracted from Escherichia coli and pseudomonas aeruginosa using three different solvents, namely trifluorocetic acid (TFA; 0.5M), trichloroacetic acid (TCA; 6 per cent w/v) and formic acid (1.0M) Extracts were assayed for uridine 5'-triphosphate (ATP), and guanosine 5'-triphosphate (GTP) by using anion exchange radial compression high performance (pressure) liquid chromatography. The three extraction produres were compared for yield of triphosphates. E. coli, the TFA extraction procedure was more sensitive and reliable than TCA and formic acid extraction procedures, but , in P. aeruginosa, the best yields of ATP and GTP were obrained following extraction with TFA. Yields of UTP and CTP increased when extraction was performed in TCA. These data illustrate that different extraction produres produce different measures for different triphosphates, a point often overlooked.

The effects of a computer program (Health Imagery Technology Systems, HITS) designed to promote attitude and cognitive changes through elicitation of evoked response potentials were evaluated with chronic pain patients. A treatment and control group were used for comparison (52 patients, 22 females, 32 males, mean ages 47). Wechsler Adult Intelligence Scale-Revised subtests, a Semantic Differential scale, the Health Attribution Test, an imagery protocol, the McCoy-Lawlis Pain Drawing, and the Zung Depression scale were used at admission and discharge to measure change. A pre- post-mood thermometer was used with the treatment group. The hypotheses that the treatment group would show significant changes on these measures were tested with a two group repeated measures analysis of variance design. No significant changes were noted for either group on the intellectual measures, on health attitudes, or reports of pain. The similarities subscale showed significant within group variance (F = 5.46, p < .023). One bipolar adjective pair indicated significant differences (F = 4.79, p < .035), possibly a result of chance. One of seven imagery measures suggested a significant improvement in strength of imagery for the treatment group (F = 18.2, p < .00008). Both groups showed significantly improved imagery of body defenses …

The purpose of this study was to validate a stress inventory which would differentiate between a normative group and a patient population suffering from environmental illness. The hypotheses of this study were: (1) the Total Stress Load Inventory would be predictive in discriminating between clinical ecology patients and a normative group; (2) each section or subscale of the Total Stress Load Inventory would be predictive of psychological, cognitive, nutritional, and/or medical factors.

The hypothesis was tested that meditation using an audible word-sound would be superior to silent repetition of the same word in producing decrements in autonomic arousal and improvements in anxiety, mood, and the ability to cope with stress. The influence of hypnotic susceptibility upon improvement was also evaluated. Thirty subjects, assigned to one of three groups: audible meditation, silent meditation, and relaxation control, met one hour weekly for six weeks to practice their respective technique and discuss their progress. All subjects were evaluated using the Harvard Group Scale of Hypnotic Susceptibility, a medical symptom checklist, the Spielberger Trait Anxiety Scale, a self-rating of state anxiety, and factors C and Q4 of the 16PF. Finger temperature was taken as a measure of physiological arousal. Confidence ratings of the respective strategies were taken pre- and post-treatment.

Psychological research suggests that Ritalin reduces the rate of maladaptive behaviors in hyperactive children but does not improve their academic performance. Teachers, however, often assert that writing skills and other graphic work are improved by Ritalin. Twenty elementary school children who had been diagnosed as hyperactive and who were taking Ritalin were tested using WISC-R coding, WISC-R block design, and Bender Gestalt. Ten of the subjects were assigned to a group which was first tested when the children were off Ritalin and subsequently tested when they were on Ritalin. The sequence was reversed for the remaining ten. This procedure was designed to counterbalance the effect of practice. Direct difference t-tests indicated that there were no differences between groups regarding any of the three dependent measures. Thus, results indicate that the popular conceptions among educators regarding the efficacy of Ritalin for improving visual-motor efficiency is open to serious question.

This study examined the relationship among the factors of parental stress, marital adjustment, life event stress, and behavior problems of children and whether the sources and levels of parental stress, marital adjustment, and life event stress differed among families of children with . behavior problems and families whose children did not experience behavior problems. The subjects for this study were 60 mothers and their children from the North Texas metropolitan area chosen from two populations. Group I was composed of mothers of 30 children referred to a university related counseling center for behavior problems. Group II was composed of 30 mothers of children identified as not experiencing difficulty. Each mother completed the Parenting Stress Index (PSI), Short Marital Adjustment Test (SMAT), and Social Readjustment Rating Questionnaire (SRRQ). Hotellings T tests were used to determine whether the groups differed on sources and levels of parenting stress, marital adjustment, and life event stress. The groups differed significantly on the variables of sources and levels of parenting stress but not on marital adjustment or life event stress. The multiple regression technique was used to determine which variable or combination of variables would predict group membership. Parenting stress was found to be the best …

Postoperative spinal patients were randomly assigned to one of three treatment conditions and were taught five adaptive movements by occupational therapists. The Control group received routine hospital occupational therapy; the Placebo group participated in an imagery relaxation task unrelated to the mental practice task of the Imagery group, which was shown line drawings of the adaptive movements under study, provided movement instructions, and asked to mentally practice each movement in a familiar, daily living situation. Thirty-five patients returned for follow-up, and a measure of outcome was obtained through the use of a quantified movement assessment instrument. Subjective ratings for anxiety, rumination, and imagery were made by the occupational therapists. An occupational motoric-symbolic rating scale was developed to assess the symbolic portion of the patient's job experience. Statistical procedures including chi square, analysis of variance, and Pearson correlation were performed. Results were in the predicted direction although statistical significance was not achieved. Possible explanations for the obtained results were discussed.

The problem with which this investigation was concerned was that of the use of parents as therapeutic agents. The purpose of this study was twofold. The first was to determine the effect of filial therapy on parental acceptance, self-esteem, parent-child relationship, and family environment. A second was to analyze the results and make recommendations concerning the effectiveness of filial therapy as a treatment modality for parents and their children. The experimental design of the study was a nonrandomized, pretest-posttest, control group design.The sample (N=47) consisted of the experimental group (parents N=15, children N=9) who received filial therapy and the control group (parents N=12, children N=ll) who did not. The treatment included ten, two hour weekly parent training sessions. During these sessions the parents were taught the principles of client-centered play therapy and were instructed to conduct weekly one-half hour play sessions at home with their own children. Based on the findings of this study, the following conclusions were drawn: 1) Filial therapy does significantly increase the parents' feeling of unconditional love for their children and 2) Filial therapy does significantly increase the parents' perception of expressed conflict in their family. In addition to the statistically significant results, there were some …

The possibility that faulty expectations about success and relapse recovery contributed to poor adherence was examined in this study. Support for such an expectancy model was sought through comparing an index of relative task magnitude to adherence rates. Instructions designed to improve adherence through changing expectations about relapse and relapse recovery were also administered to 46 clients in two clinical nutritional programs. Their adherence rates <in days) were compared to the rates obtained from the records of 64 other clients who did not receive the instructions. To further understand the adherence phenomenon, several other measures were obtained from the treatment subjects. These data were compared to adherence rates in an attempt to identify potential co-variate relationships. Statistical procedures including analysis of variance to determine comparability of subject groups, Pearson Product Moment correlations, t tests of the difference between means, and the Lawshe—Baker Nomograph comparing per cent adherence rates were performed on the data. Obtained results did not support the predicted relationship between relative task magnitude and adherence. This may have been due to differences between subjective assessments of task magnitude and the objective measure used in this study. Although improvement in adherence was noted in both treatment groups, statistical significance …

To investigate the effects of emotional arousal on information processing strategy, three different moods (sadness, anger, and happiness) were hypnotically induced at three different levels of intensity (high, medium, and low) in 29 male and female undergraduate students, while engaging them in a visual information processing task. Subjects were screened for hypnotic susceptibility and assigned to either a high susceptibility group or low susceptibility group to account for the attentional bias associated with this trait. All subjects were trained to access the three emotions at the three levels of intensity. During separate experimental sessions, subjects were hypnotized, and asked to access a mood and experience each level of intensity while being administered the Navon Design Discrimination Task, a measure of global and analytic visual information processing. Scores were derived for global processing, analytic processing, and a percentage of global to analytic processing for each level of mood and intensity. Two (hypnotic susceptibility) x 3 (emotion) x 3 (intensity level) repeated measures ANOVAs were computed on the global, analytic, and percentage scores. In addition, two separate ANCOVAs were computed on each dependent measure to account for the effects of handedness, and cognitive style. None of these analyses revealed significant main effects …

This investigation traces the history and development of music theory in Mexico from the date of the first Mexican treatise available (1776) to the early second half of the nineteenth century (1866). This period of ninety years represents an era of special importance in the development of music theory in Mexico. It was during this time that the old modal system was finally abandoned in favor of the new tonal system and that Mexican authors began to pen music treatises which could be favorably compared with the imported European treatises which were the only authoritative source of instruction for serious musicians in Mexico.

The problem of this study was the roles of the general assembly agencies of the Presbyterian Church in the U.S.A., the Presbyterian Church in the U.S., and the United Presbyterian Church of North America in the development of Barber- Scotia College, Knoxville College, Johnson C. Smith University, Stillman College, and Mary Holmes College. The historical records of these three churches for the period from 1866 to 1983 were examined to analyze the factors surrounding the establishment of the five colleges, the differences and similarities in the administrative practices of the general assembly agencies charged with operating the colleges, the relationships of the colleges to the churches in the transition from dependent mission schools to independent colleges, and to identify way in which the Presbyterian Church (U.S.A.) may improve its support of Black higher education. The Presbyterian Churches established the mission schools to meet the religious, educational, and economical needs of the emancipated Black slaves. Though the three 2 churches had differences over the issues of slavery and doctrine, the administrative systems developed for the operations of the schools were very similar. All treated the missions schools as remedial temporary measures necessitated by the refusal of Southern and border states to …
