The current study examined two methods of language sampling (interview and the Dixit Method) in early adolescents with typical language development. The purpose of this study was to examine the effectiveness of the two procedures in eliciting lexical diversity in spoken language samples in the early adolescent population. To examine lexical diversity, traditional methods of analysis (type token ratio, average type token ratio, and mean length of utterance) were applied. However, because literature historically alludes to flaws in these traditional methods, the researchers also applied an ecological approach to analysis of lexical diversity proposed by Scott Jarvis (2013). Student participants (n = 22) in the sixth grade (11:0 -12:11 years of age) were recruited through a local middle school. Both methods of language sampling were compared in a within-subject design for diversity of spoken language samples by applying the previously mentioned analysis procedures. The data was evaluated using a pairedsamples two-tailed t test. Although the sample size was small, evidence from this study indicates the Dixit Method provides a more holistic view of lexical diversity than the traditional method by considering six ecological components that are reflected in typical language use.

The traditional role of speech-language therapists as feeding specialists appears to have focused primarily on the mechanics of feeding disorders, without fully considering the impact of nutritional needs on a child's development and communication. The aim of the study was to investigate the experiences and perceptions of a group of speech-language therapists regarding nutritional issues in children requiring feeding therapy or early communication intervention. A qualitative research design was employed in the form of a descriptive survey and a questionnaire was compiled as the data collection instrument. Forty-nine questionnaires were delivered to speech-language therapists within the Johannesburg and Pretoria geographical areas, of which 32 were suitable for analysis. Closed ended questions were analyzed quantitatively using descriptive statistics while responses to open-ended questions were categorized thematically. Results indicated that all respondents came into contact with clients who had, or who were at risk for, feeding disorders and nutritional deficiencies. However, findings revealed that during assessment and treatment of these clients, respondents tended to neglect issues related to nutrition, as well as psychosocial issues pertinent to feeding disorders. Furthermore, respondents appeared not to have fully realized the importance of their role as communication specialists within the feeding context. It was found that the majority of respondents were involved within a multidisciplinary team approach; however, the application of the more effective transdisciplinary approach was limited. This was confirmed by results revealing that collaboration with other professionals, such as dieticians, did not consistently occur. In terms of training, it was evident that respondents received the majority of their training in feeding therapy from continued education, which included aspects of nutrition. However, undergraduate training was perceived as having limitations within the theoretical content as well as practical application, and did not incorporate nutritional aspects. In light of the apparent need for a more holistic view of paediatric clients with feeding disorders, suggestions were made regarding the inclusion of vital nutritional issues and psychosocial factors within training and transdisciplinary service delivery in South Africa. Furthermore, relevant research topics within the field of paediatric feeding were presented. Broadening perspectives by means of holistic research and training may enhance service delivery to children with paediatric feeding disorders. / Dissertation (MCommPath)--University of Pretoria, 2002. / tm2015 / Speech-Language Pathology and Audiology / MCommPath / Unrestricted
