The purpose of this study was to make an assessment of the probable effects of extraneous stimulation on both cognitive achievement or learning, and emotional reactions and autonomic arousals of students. While the focus of interest was upon possible disruptive effects, the kinds of measurements projected would make it possible to observe some effects of either kind, disruptive or facilitative.

It was the purpose of the present study to compare the effect of intraperitoneal injections of the following drugs on a conditioned approach-avoidance response in mice. These drugs were epinephrine and nor-epinephrine.

This present study compares the effect on intraperitoneal injections of the following drugs on a conditioned approach-avoidance response in mice. These drugs were epinephrine and Normotensin, an epinephrine neutralizing hormone.

The present study was designed for the purpose of comparing the effectiveness of two methods of orchestral programming, demonstration and non-demonstration, upon (1) the musical perception of the members of a student body audience, and (2) the attitudes of the members of a student body toward orchestra as a school subject. This comparison of demonstration and non-demonstration programming involved the question concerning the effectiveness of instructive listening as compared with free listening in the development of musical perception and attitudes. The problem of the present study is presented in the following major areas: (1) musical perception, end (2) attitudes.

The purpose of this study was to identify reading achievement of pupils assigned to the reading clinic and analyze and compare this achievement by grade levels with levels of intelligence. More specifically, the investigation attempted to determine: 1. The grade level at which the reading clinic was most effective; 2. The intelligence level at which the reading clinic was most effective; 3. The statistical significance of the variation in group intelligence test IQ's; and 4. The correlation between group intelligence test IQ's and total reading achievement.

The purpose of this study was to test the effectiveness of studies in depth utilizing selected materials which had been developed for teaching high school American history.

The purpose of this investigation was to study the effects of decreasing barometric pressure upon the pressure-flow relationships in a peripheral vascular bed in an attempt at better delineation of the autoregulatory mechanisms. A decrease in barometric pressure does influence the transmural pressure and could theoretically affect smooth muscle tone. An evaluation of the extent of the transmural effect is essential to understanding vascular dynamics at altitudes.

The purposes of this study are 1) to investigate the development of physical fitness through the medium of fifteen-minute exercise routines in junior college physical education classes; 2) to determine the relationship between each of four exercise routines and the improvement of physical development in a specific body area; and 3) to compare the results of intensive, isometric, calisthenic, and continuous exercise routines to determine if any one routine was of greater value to three alternate routines in assisting the individual to attain a higher degree of physical fitness development.

It was the purpose of this study to investigate the dynamics that exist in a classroom speaking situation. In particular, the study sought to explore the relationship of the speaker to his audience and how the quality of this relationship would affect the ability of the speaker to communicate.

The principle problem of the present research was to determine the relative effects of two major variables, nature of verbal reinforcement and achievement history, upon the performance of elementary school children on a relatively simple learning task.

The effects of short duration exercise routines on the development of physical fitness.

The problem of this study was to compare the relative gains made in the development of oral language skills in two groups of first grade pupils when two different approaches to beginning reading instruction were used. The two approaches were: (a) the language experience approach, Approach A, and (b) the traditional basal reader approach, Approach B. The six aspects of oral language development considered were: extent of verbalization, spoken vocabulary, expressions of tentativeness, use of structural patterns, colorful and vivid expressions, and use of mazes.

A study was made to investigate the relative effectiveness of two methods of training on the development of arm strength. The purposes of the study included the following: 1. To determine functional arm strength of male students enrolled in physical education classes selected for the study. 2. To conduct specific exercise programs in each of the selected classes. 3. To determine the relative effectiveness of the selected programs in developing arm strength.

It was the purpose of the investigation to determine the effects of selected high intensity monochromatic radiations on the growth of pith callus tissue of Pelargonium zonale, variety Enchantress Fiat. In addition, the extent of cell differentiation was to be determined for tissues grown under each experimental treatment.

The purpose of this study, therefore, was threefold in nature: (1) to determine the effects of x-irradiation on the influx and efflux of potassium in compound nerve fibers (2) to attempt to relate the radiation-induced changes in electrical activity with potassium flux and (3) to use the information obtained to gain insight into the possible cellular site (s) of radiation insult to compound nerves.

It is the intent of this present study to investigate the nature of the relationships which might exist between ego strength, dogmatism, and anxiety.

It is the purpose of this thesis to report further studies on the vesicles appearing in phage lysates of Escherichia coli, phage attachment to these vesicles, and the presence of similar vesicles in lysozyme and penicillin lysed cultures.

The objective of this investigation was to determine the electronic effects of the halogen atoms in dihaloketenes such as dichloroketene and dibromoketene.

This thesis discusses elliptic geometry including the order and incidence properties, projective properties and congruence properties.

It was the purpose of this study to investigate some of the factors related to employers' attitudes toward the hiring of a mentally retarded individual. More specifically, an attempt was made to answer the question, "Why do employers hold favorable or unfavorable attitudes toward the hiring of the retarded?"

This thesis is a report of a study of the employment of foster grandparents for the foster grandparent project at the Denton State School in Denton, Texas. There were three specific interests in the study. First, it attempted to ascertain what criteria were used for the hiring of foster grandparents and how they were hired. Included in this area were the necessary steps which an individual had to take to apply for employment. Second, the study was concerned with developing a general description of the social and economic characteristics of those who were hired as foster grandparents, including their performance on certain tests which they took during the employment process. Third, it examined the relationship of selected social and economic characteristics to each other, the inter-relationships of test performance, and the relationships between the selected characteristics and test performance.

This study looks at Aelfric's "Passion of Saint Sebastian, Martyr" from an etymological perspective.

The problem of this study was to evaluate the effectiveness of a guidance-structured summer session for entering university freshmen. The performances of students entering this type of program were compared with those of students entering a traditional type of summer school. Inferences made relating to the contributions of a guidance-structured summer session to entering university freshmen were based on analyses of the following characteristics: (1) performance on standardized tests; (2) certain aspects relating to high school background; (3) academic achievement and retention at Texas A. and M. University; (4) fathers' attendance at Texas A. and M. University; and (5) fathers' occupations.

The problem of this study was to determine the effectiveness of the use of a mechanical pacing device in improving the typewriting skills of students in intermediate and advanced typewriting classes at the college level.
