The SRA-10 is a tactile instrument which provides hearing impaired subjects with acoustic transforms that can be easily discriminated on the skin. Whether or not the SRA-10 is an effective means of training speech-language skills in profoundly hearing impaired subjects was the focus of this investigation. Two profoundly hearing impaired subjects were trained on phonetic reception/production tasks and on discrimination of multisyllabic words. Each subject served as his own control, wearing the SRA-10 for 14, 30 minute sessions, and a Bioacoustics 70-B auditory training unit for the same period of time. Results indicated a greater correct performance gain function with the SRA-10 than with the 70-B, suggesting that speech perception/production training using the SRA-10 or similar device would be superior to training using acoustic amplification.

The work deals with social communication. Its main task is to structure the subject and to apply the social communication analysis focused on youth group. In its first part, the theme is conceived in general. It defines the term and its place in sociology and other social sciences. The work characterizes a framework of social communication (communicative act, participants, communication channel). It also describes the division of communication means and their possibilities. It analyzes the content and styles of communication process, functions and purpose of social communication. It also discusses the factors that affect communication (communication context, the means used for communication, participating persons and social environment). The second part is devoted to my own case study of the social communication of youth in chosen Kolínsko region. It detects means of communication used by youth, it deals with the question whether the youth prefer the possibilities of personal communication or the usage of modern means of communication; which communication topics they use with their friends and which they use with their parents and what is the purpose of communication with different types of communicators (parents / friends). It also focuses on the usage of communication accompanying phenomena (emoticons,...

The work deals with social communication. Basic formal work arrangements is conducted from the theoretical anchoring the topic of practical knowledge in the field of social communication youth. The space here is devoted to the definition of social communication, comparing her relation with interaction and by negotiation, further then her frame (communication act, actors, communication channels - communication media, functions and purpose of the communication). For orientation deals with social communication, socialization of youth in the family, school and friends. Paies also free time youth and his usage. Followed by a section containing the results of my own empirical investigation and comparison with previous studies.This part is devoted to my own case study of the social communication of youth in chosen Kolínsko region.

The purpose of the study was to investigate the influence of the quantity of adult language input on their deaf and hard-of-hearing preschool children and to explore the effects, if any, on the child’s quantity of language, vocabulary development, and basic concept understanding. Using audio recording and the Language ENvironment Analysis (LENA) software, the study involved 30 preschool children with hearing loss who used spoken language as their communication modality and 7 children with normal hearing. Their language and the language spoken to them in all waking-hours of a two-day period (16 hours per day) were recorded and analyzed quantitatively as adult word counts (AWC), child vocalizations (CVC), and conversational turns (CTC). These components were compared to the child’s performance on the Boehm Test of Basic Concepts (BTBC-3) and the Peabody Picture Vocabulary Test (PPVT-4) to investigate if the quantity of language input had an effect on the child’s usage of vocabulary and basic concepts. Correlations were found between the amount of adult words, child vocalizations, and conversational turns across weekends and weekdays, but not on BTBC-3 or PPVT-4 scores. Interestingly, there were no significant differences between adult word counts and child vocalizations as a function of the child’s hearing loss, indicating parents of deaf or hard-of-hearing children are using as many words with their children as parents of children with normal hearing. Additionally, scores on the BTBC-3 and PPVT-4 were correlated with each other, but there wasn’t a statistically significant difference between the mean scores for children with normal hearing and the children with hearing loss, indicating both groups scored similarly on the assessment. Results from this study suggest the language used around children impacts their language use and the amount of interactions they have in their environment. This is significant because it identifies the influence of the quantity of adult language input on the child’s language development.

Group-level differences in classroom language environments were analyzed to better understand implementation of best practices with learners with deafblindness (DB), and whether state certification practices, student characteristics or specialized training related to differences in adult language modeling. Participants came from four states with three distinct teacher certification policies. Data was collected from 15 teacher-student dyads through behavioral coding of videotaped language samples from classrooms, teacher surveys and Communication Matrix assessments. In our sample, teachers used verbal communication significantly more than additional classroom staff. Teachers in a state that required a severe/ profound certification used significantly higher rates of visual communication. These teachers were also the most likely to match their students’ expected receptive modalities. Classroom staff in a state with interveners used significantly more tactile communication with learners. Overall, teachers were more likely to match their students’ expected receptive modalities when the students had higher levels of communication. The students with DB were highly heterogeneous and there was no association between level of dual sensory loss and students’ expressive communication levels. Discussion focused on whether our current use of communication modalities are sufficient, or whether more diverse language modeling (i.e., augmented input) would be beneficial in classrooms with learners with DB. These quantitative results can empower teachers to advocate for the use of specific communication modalities, such as American Sign Language, and trained personnel, such as interveners, in their districts.

This diploma thesis deals with means of communication of The Motol University Hospital. The objective is to find out, which means of communication the hospital uses for communication with patients and hospital visitors and which are used for communication with its employees. Next I describe them and find out, which means of communication suit these two groups, which don't and where is the room for improvement. The questionnaire survey was used to find out the preferences of means of communication, which I realized in The Motol University Hospital. The work includes research findings and recommendations resulting from their foundations.
