An investigation of respiration in stuttering. Australia leads the world in stuttering research, and this project will maintain that profile. The research aims to establish if breathing has a causal role in stuttering. The new knowledge produced will support or weaken current theories of the cause of stuttering and will contribute to understanding the nature of the disorder. In particular, it will be applied to develop more effective and efficient treatments for chronic stuttering.
Establishing the relationship between anxiety and stuttering. The present project will establish basic knowledge about the disorder of stuttering, which will contribute to offsetting the personal and community costs of the disorder by guiding empirical investigations into its nature and the development of future treatments. Further benefits at the population level will occur by provision to the public of basic information about the disorder assembled from this project. By conveying information f ....Establishing the relationship between anxiety and stuttering.

Further benefits at the population level will occur by provision to the public of basic information about the disorder assembled from this project. By conveying information from the present project to clinicians who treat stuttering patients, the project will benefit Australians who stutter.Read moreRead less
Speaking my language: International speech acquisition in Australia. It is important to differentiate between children who have communication impairment (difficulty learning all languages) from those who only have difficulty learning subsequent language(s). Communication impairment in multilingual children is both undiagnosed and over-diagnosed due to lack of culturally-sensitive measurement tools. Early intervention can ameliorate communication impairment in children and can reduce subsequent e ....Speaking my language: International speech acquisition in Australia. It is important to differentiate between children who have communication impairment (difficulty learning all languages) from those who only have difficulty learning subsequent language(s). Communication impairment in multilingual children is both undiagnosed and over-diagnosed due to lack of culturally-sensitive measurement tools. Early intervention can ameliorate communication impairment in children and can reduce subsequent educational, social and occupational outcomes of untreated communication impairment. By working with people around the world, this Fellowship will result in the development of the International Speech Assessment designed to differentially identify children and to specify holistic early intervention goals.Read moreRead less
Children with speech impairment: A population study of prevalence, severity, impact and service provision. Compared to the general community, adults who had a speech impairment as a child typically achieve lower levels of education, have greater literacy problems, experience significant social problems and discrimination, and have decreased occupational opportunities. The social and economic cost of untreated speech impairment for individuals, schools and society is large. This landmark study wi ....Children with speech impairment: A population study of prevalence, severity, impact and service provision. Compared to the general community, adults who had a speech impairment as a child typically achieve lower levels of education, have greater literacy problems, experience significant social problems and discrimination, and have decreased occupational opportunities. The social and economic cost of untreated speech impairment for individuals, schools and society is large. This landmark study will identify strengths and limitations in the health and education sectors regarding appropriate and holistic services for children with speech impairment combining identified prevalence, severity and impact data.Read moreRead less
Factors impacting on workplace retention in speech pathology. Retention of speech pathologists within their profession and within the public service is presenting a major problem for the professional association, the public service and service users. In repsonse to this situation our study aims to measure the psychological well being of speech pathologists nationally and to identify workplace dimensions that are hindering or enhancing retention. The results of this study will be of significance ....Factors impacting on workplace retention in speech pathology. Retention of speech pathologists within their profession and within the public service is presenting a major problem for the professional association, the public service and service users. In repsonse to this situation our study aims to measure the psychological well being of speech pathologists nationally and to identify workplace dimensions that are hindering or enhancing retention.

Tonal language development in Mandarin and Cantonese-speaking children with cochlear implants. Cochlear implantation in children is expanding in countries where tonal languages are spoken, despite limited evidence of the effectiveness of implant use in these settings. This project will examine the impact of implant use on children's perception of tone, their production of speech and assesses how this affects functional communication.
Brain structure and function of neonates at risk for stuttering. The aim of the project is to determine whether the brain abnormalities that have been found in people who stutter are present at birth. The hypothesis is that the brains of neonates who subsequently start to stutter will differ significantly from those who do not. This is the first project to investigate the brains of infants before they start to stutter.
