Several studies have been undertaken to determine the incidence of recovery from stuttering; however, the results of these investigations are not reliable due to methodological limitations. For the most part, ex-post-facto recall judgements on the parts of adults or parents of young children were relied upon in gathering data for the research. It would appear that a requisite factor in determining incidence of recovery from stuttering should be the use of a formal instrument which would quantify the auditory and visual aspects of speaking behavior to determine the presence or absence of stuttering. The primary purpose of this study was to determine the incidence of recovery from stuttering in a sample of children who had received treatment for stuttering and had subsequently been dismissed from treatment. Also examined was whether or not significant differences existed between the speaking performances of these subjects and a sample of control subjects of the same sex, grade level, and approximate academic ability. To control for experimental bias, a double-blind design was utilized. A secondary part of this study examined the possible effects of the former treatment received by the experimental subjects on the recovery from stuttering.

For over a quarter of a century a difference of opinion has existed regarding the relative value of auditory training in the education of the deaf child. The opponents have insisted that in most deaf children there is little or no residual hearing on which to use acoustic stimulation. The proponents have insisted that there are extremely few deaf children who do not have some residual hearing which could be stimulated to promote better speech, to increase speech perception, and to advance better mental health. The purpose of this study has been (1) to investigate (a) the development of speech perception by the use of acoustic stimulation in schools for the deaf, and (b) the general tendency toward the use of the acoustic method in the schools for the deaf; and, (2) to determine whether or not auditory training has a definite place as an educational tool in the education of deaf children.

Statement of the problem. The present study was designed to answer the question: What is the effect of tranquilizers, specifically phenothiazines , on diadochokinetic movement in a geriatric population? It was hypothesized that patients exhibiting overt effects of long term phenothiazine therapy (dyskinesia ) would show a reduced rate of diadochokinetic movement when compared with an age-matched group exhibiting no such symptoms and with no history of having taken tranquilizers . Furthermore, if this diadochokinetic movement were reduced, there would be a greater incidence of defective speech in this patient group .

This study is aimed at analyzing the speech adequacy of credential candidates. It is hoped that the results will suggest a type of speech training, in terms of a specific course, which will be beneficial to those candidates who are in need of speech help. If what the candidates as a whole seem to need and what they seem to have acquired through speech training is known, a course designed along the lines of these speech needs can be more easily constructed. In general, this thesis will attempt to answer the following questions: (1) What type of speech training would be most beneficial to credential candidates?; (2) Do credential candidates who have had one speech course have more adequate speech abilities than those who have had none?; (3) Is the speech of those candidates who have two or more speech courses more proficient than those who have had only one course?; (4) What particular courses, if any, seem to have contributed most to increased proficiency?; (5) What is the most serious deficiency in the speaking ability of the credential candidates? An attempt will be made to answer these questions by indicating tendencies. The conclusion of this thesis will also propose other issues of particular significance or interest which might be used in future investigations.

The primary purpose of this study was to provide a comprehensive description of a school hearing conservation program that might be used by personnel planning other programs, to serve as a guide or for comparison. A secondary purpose of the study was to analyze and evaluate the hearing conservation program of the Office of the Stanislaus County Superintendent of Schools in order to find more efficient ways of administering and conducting the program and otherwise improve its effectiveness.

It was the purpose of this study (1) to throw light upon specific speech needs of pupils in one of the elementary schools in Stockton; (2) to throw light on the status of speech in a school population among which the factors of low I.Q. retarded academic progress, exceptionally limited economic background, and racial and national differences, and relatively small; (3) by extension, to indicate something more generally regarding the speech needs of such children of whom the pupils surveyed tended to be a representative group; (4) to find indication of the influence of the factor of chronological age upon articulatory accuracy; (5) to throw light upon the question of the extent to which maturation, rather than training, can be relied upon for the elimination of speech errors in children; (6) to find indication of the influence of the factor of sex upon articulatory accuracy; (7) to discover, among students manifesting inaccuracies, to what extent the inaccuracies tended to be manifested in a relatively large number of sounds, and to what extent they tended to be limited to relatively few sounds; (8) to find indications as to which sounds are most difficult, i.e., most frequently inaccurate, and which sounds are least difficult, i.e., least frequently inaccurate, among primary school children; and (9) to find indications as to the relative frequency of errors in the initial, medial, and final positions of words, respectively.
