First of all, in order to measure the effects of our training toward severely retarded adults in our institute, we try to make a check list which aims to evaluate their basic abilities. This check list consist of three categories. The first is called as "abilities of physical movements", e.g. movements of legs and arms, audition, and vision ete.. (Ability 1) The second is named as "abilities for spending his daily life", e.g. putting on or taking off clothes by himself, going to toilet by himself, etc.. (Ability 2) The third is called as "abilities which can recognize external stimulus and actively respond those stimulus". (Ability 3) we want to emphasize that Ability 3 must be the most important part to measure the effects of our training. The surveies by our check list had done twice. The first one was January of 1973, the second one was January of 1974. Subjects of this study were severely retarded adults who were accomodated Hachioji Fukushien Institute under the Tokyo Metropolitan Government. survey The member of the subjects in the first survey were 84 male and female and 95 in the second survey. Main results were summerized as follows: 1) We verified that Ability 3 was important indicator which shows positive improvement of their behavior. 2) We verified that whenever the points of Ability 3 increase, points of the other two abilities also increase. This means that it is enough to make efforts to improve Ability 3, as far as training for severely retarded are concerned. So, according to the results of our serveies, we concluded that our check list which stressed Ability 3 was appropriate for behavioral evaluation of severely retardeds. Next stage of this study will find actual techniques to change Ability 3 under the control of learning theory.

The purpose of this study is to compare with the mental development, the physical growth and the motor development of the three karyotypes of chromosome in Down's syndrome. The subjects were 122 children which were diagnosed as Down's syndrome by the chromosomal analysis using peripheral leucocyte culture. They were divided by the three groups, namely, Trisomy-type (100 cases), Translocation type (12 cases) and Mosaic-type (10 cases) of Down's syndrome. They were investigated at (1) the Mental and Motor Developmental Test, (2) physical Mesurement (Height, Weight, Head Circumference) and (3) Developmental milestone in infantile period. The results are as follows; (1) The mean DQs of 61.8 in the mosaic-type of Down's syndrome was significantly higher than tho other two groups. (trisomy-type; mean DQs of 52.3, translocation-type; mean DQs of 58.5) (2) The physical growth of Down's syndrome was strikingly retarded as compared with that of normal children with the same aged. To analyze the growth of their height, the height quotients were calculated by the next for mula; H.Q.=Height Age/Chronological Age × 100 The mean HQs in children of mosaic-type were higher than the other two groups but not statistically significantly. (3) The mean MQs of the mosaic children were significantly the highest of all mongols. And there were no significant difference between the trisomytype and the translocation-type. (4) On the average ages at which the children controlled head and first walked the mosaic mongols showed also the best development.

This paper describes some further attempts to identify and measure some parameters in the speech signal that reflects the easiness of hearing for the listener. From some literatures this psychological perception assumed to be constructed by suprasegmental informati ons and linguistic informations. Though such suprasegmental parameters can be supposed to be inherent in speech, they have been ignored on the speech therapy in Japan. Therefore three experiments were projected to study some psychological aspects in speech signal, with these parameters. Various 10 minutes recordings were obtained from the readings of a professional announcer, two semipro-fessional announcers and 5 students by reading a literature. Excerpted portions of these readings were subjected to hearing tests and a segmental analysis, and all portions of them were subjected to study some psychological aspects in speech signal. Procedures Exp. I. Hearing test: We saw whether the two excerpted portions can be defined the ranks of the easiness to hear of oral readings for several listeners. Seven normal adults were asked to judge whether one of the 30-50 sec. oral readings had the easiness of hearing or another. Each test trial was 28 randomly arranged oral samples by the method of paired comparison. Exp. II. Acoustic analysis: Suprasegmental features were obtained from some parameters of oral readings. Oral samples which 8 speakers read for 10 minu ites were ana lysed into a duration of sound groups, and a pause. Further, each sample in Exp. I. was analysed into a fundamental frequency (Fo) contour in ramps. Acoustic correlatinos were obtained from the patterns which consited of these suprasegmental parameters and the easiness to hear of the samples. Exp. III. Segmental analysis: To confirm the suprasegmental features carry a information with regard to the linguistic content of a message was examined in a segm ental analysis. Results 1. There were clearly the differences of the easiness to hear of oral sample readings. (Tab. 2) 2. The differnces were matched very good to the pattern consisted of the suprasegmentals in oral readings. (Fig. 6) 3 Most long pauses were occured at the end of the sentences. (Tab. 4)

This paper concerns the after effect of delayed auditory feedback (DAF) on the stutterers' speech fluency. Subjects were seven adult stutterers. Test 1. They were instructed to read or talk very slowly and with a prolonged pattern of expiring for about six minutes under DAF conditions. Six of them were free from blocking under DAF, and after taking away DAF conditions their speech fluency was remarcably improved. Test 2. Six subjects of them were instructed not to use a prolonged pattern of expiring under DAF. In this case they were free from blocking under DAF, but their speech fluency after taking away DAF conditions was not improved. Test 3. Five subjects, who were comparatively severe, were instructed to speak as normally as possible under DAF conditions in which delay intervals were shortened to 75 msec. Under DAF conditions their speech was blocking-free. And they reported that they could speak more fluently than under the other DAF conditions. But their speech fluency after taking away DAF conditions was not improved. From these findings, it is suggested that for improving the speech fluency of severe adult stutterers, slow and blockingfree speaking with a prolonged pattern of expiring under DAF may be effective.

The present study was designed: 1. To observe a verbal learning process of a severely handicapped cerebral palsied child (female, 3 years old). 2. To explore how the verbal learning depends upon the identification by motor-activities. The results are as follows: 1. The verbal learning process of a severely handicapped cerebral palsied child could be observed. 2. The patient girl, who could have neither spoken nor communicated with others before, came to communicate with particular persons by using her hands after given training. 3. The finding of this experiment indicates that however severely handicapped a child may be, it is necessary to teach him means of commnnication as earliest as possible in his life. And it comes to the point that identificafion by "motor-activities" are one of the effective methods to help the children to develop their verbal behavior.

MOTIVATION: The development of special education of the progressive countries has been very great. Unlike Taiwan, their language teaching in the education for the deaf has also been developed in those scientific methods of oral, lip-reading, speech-reading and hearing, therefore it is of great necessity that we have to study the conditions of the progressive countries. Though Japan and America began their education for the deaf much later than some European countries, yet they have had many outstanding effects. Therefore, in order to improve the education for the deaf in Taiwan, I would study the language teaching of these two countries. To the deaf, the manual communication is their native language, no matter how oral method is improved, we still should not and could not neglect or give up the manual communication method. Those countries, such as Japan, America., Russia, Denmark and England have recently paid great attention to the sign and manual system. In a lot of researches and experiments they reported that the manual method (including fingerspelling) doesn't hinder the oral and speech training of the young deaf children. And the widely-known oral method which has been the most popular method in the deaf education for nearly a century should be re-evaluated.Besides, it is necessary for the teachers of the deaf in Taiwan who have yet taught mainly in manual method to have a real recognization of the existing condition of the practical manual method. Therefore this study is mainly centered on comparing and analyzing the practictical manual method based on America, Japan, and Taiwan. PROCEDURE: First to study the literature of the establishment and changing of the education for the deaf in America, Japan, and Taiwan. Next to compare and analyze every kind of language instructions, (manual method, oral method, combined method, etc.) and see what advantages or disadvantages they resulted. Then to compare the manual communication method in America, Japan and Taiwan (As to their method I will explain in photoes.). And the last, to inspect the education for the deaf in Taiwan and see the way to improve it. SUMMARY: This study is made up of five chapters. In the first chapter, the establishment and the background of the organizations established of the education for the deaf of Europe, America, Japan, and Taiwan are introduced. Chapter two is the comparison and analysis on the theory of all the communicative methods. Chapter three is the analysis of sign language instruction and its practicality of education in America, Japan, and Taiwan. Chapter four is the comparison of signs in America, Japan and Taiwan with illustrations. The last chapter is the examination of the status quo of the education for the deaf in Taiwan, and the ways to improve it. CONCLUSION With a study of the changing and development of the education for the deaf in America, Japan and Taiwan, I come to understand that the language instruction of these three countries are all developed from manual method to combined method and then to the modern state of oral method. For ninety four years since the international conference in Milan, Italy in 1880, the most of the countries have come to the stage of oral method in educating the deaf. Yet, no matter how modernalized the teaching equipment is, the standard of the education of the deaf children is unable to equal that of the normal ones. Therefore, we again think that manual method has to be re-evaluated and reviewed. With a view on the reports of the experiments and researches of those psychologists and educators in Japan, America, England, Russia, Denmark, my conclusion is that "Manual method can obviously help with oral method, esp. in the instructions of those retarded deaf children. Manual method is the deaf's native language, to discard or forbid the use of it is not only impossible but unnecessary. For under the circumstances when its shortco
