The purpose of the present study of the herpetofauna was to obtain additional information regarding the vertebrates of Denton County, and to produce a well-preserved, cataloged collection of the amphibians and reptiles for the Museum of Zoology, North Texas State University. An understanding of the vertebrate life of the county also involves an investigation of the habitats within the county that may, in part, count for the distribution of these animals. It is well recognized that the environmental areas of the county have altered vastly during the last one hundred years. This alteration is due largely to agriculture and industry. However, there are adequate numbers of natural environments, as well as newly created ones that may contribute to the distribution of the vertebrates at the present time. Therefore, the problem not only concerned the collection of specimens, but also the identification, abundance classification, general habitat classifications, and county distribution.

This study was concerned with determining whether those foster grandparents employed at Denton State School and seen as more or less successful in job performance could be differentiated on the basis of selected psychological and sociological characteristics. In summary, it may be said that the study was exploratory in terms of the population involved but borrowed its methods and variables for investigation from studies of similar purpose of groups participating in "helping relationships."

A comparative study was made of the effects of varied time intervals of rest between warm-up and performance in the 440-yard dash by students in selected physical education classes at North Texas State University during the spring semester of 1967. This study was made to determine if the length of a rest interval after cessation of warm-up activity has any significant effect upon the subsequent performance in a 440-yard dash, and to determine if any length of rest interval facilitates performance in a 440-yard dash.

It will be the purpose of this thesis to describe and analyze the events and factors which shaped installation of the first electronic data processing system acquired by the City of Denton, Texas--a "medium-sized" municpal organization operating under the council-manager plan. Because the environment may have some degree of effect upon such an effort within the public sector, a certain amount of space will be given over to description of the community as a geographic location, as an aggregation of people engaged in varied activities, and, by implication, as a background for the operation of a municipal government.

It was the purpose of this present investigation to display the tentative relationships between self-actualization and sociometric status of adolescent school students. In light of the theoretical and related literature presented, the following hypotheses were posited: 1) students who are high sociometrically will evidence higher personal orientation inventory (POI) means than the middle or low groups on more positive POI scales and 2) students who are low or middle sociometrically will evidence higher POI means than the high group on the major negative POI scales.

The purpose of the present study is to further investigate whether or not those children who are highly accepted by their peers differ in scholastic achievement from those who are not accepted by their peers.

Through observation of young children much has been learned regarding elementary word acquisition and ordering, sentence formulation, and expansion of verbal experience; but little research regarding what precedes "the word" has been done. The present study was concerned with that period in infancy prior to communicative speech production. The purpose of the present study was to answer the question: Can one selectively reinforce a particular babble?

The study was undertaken for the following purposes: 1. To determine the present level of physical fitness of a group of mentally retarded girls at Denton State School. 2. To determine the effect of a creative dance program, devised by the author, on the physical fitness level of a group of mentally retarded girls at Denton State School. 3. To determine the feasibility of the inclusion of creative dance in an overall physical education program for mentally retarded girls.

It is the purpose of this study to test whether or not any learning does occur during the viewing of an art educational film. In order to examine this learning, an art educational film was developed and tested at North Texas State University in Denton, Texas.

The problem was to ascertain the relationship of a measure of self-actualization to a measure of mental health.

The basic purpose of the study was to investigate the relationship of secondary school student teachers' manifest psychological needs and the accuracy of interpersonal perception and the self-concepts of students. In seeking a solution to the problem, the following subproblems were investigated: 1. The relationship of student teacher manifest psychological needs and the accuracy with which the student teacher perceived the attitudes of his students. 2. The relationship of the accuracy with which the student teacher perceived the attitudes of his students and the favorability of the students' attitudes toward the student teacher.

The problem of this study was to determine the relationship between guilt and anxiety as well as the relationship of these factors to certain psychological and sociological variables. The variables were sex, ordinal position, marital status, education, religious beliefs, church attendance, happiness of childhood, discipline from parents, happiness now, parental happiness, parental education, and parental occupation.

The problem is to determine the feasibility of using student teacher observer teams trained in interaction analysis to develop the capacity of student teachers to change their classroom verbal behavior.
