Children's Changing Speech Error Patterns: Articulating, Listening, and Thinking. When children are learning to talk, they make many errors of pronunciation. Between speech onset and five years of age, their pronunciations change, gradually approaching adult pronunciations of words. Most children share the same error patterns, although 6% have difficulty acquiring intelligible speech, that affects their academic and social development. The investigation will examine factors that contribute to ....Children's Changing Speech Error Patterns: Articulating, Listening, and Thinking. When children are learning to talk, they make many errors of pronunciation. Between speech onset and five years of age, their pronunciations change, gradually approaching adult pronunciations of words. Most children share the same error patterns, although 6% have difficulty acquiring intelligible speech, that affects their academic and social development. The investigation will examine factors that contribute to the acquisition of speech in normally developing and speech-disordered populations: oro-motor skills, auditory and cognitive processing. Experiments will determine the importance of each domain for speech development. The efficacy of a novel intervention programme for children with speech disorders will be evaluated.Read moreRead less
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. 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 from the present project to clinicians who treat stuttering patients, the project will benefit Australians who stutter.Read moreRead less
Stuttering in childhood: Patterns of recovery and persistence. This project will benefit the 1 in 20 Australian children who stutter and their families. We will learn for the first time how stuttering impacts on child development in the early school years and document the relationship between stuttering and other childhood conditions. The study will produce much needed information about recovery from stuttering and stuttering persistence. Therefore new knowledge will result to inform the scienti ....Stuttering in childhood: Patterns of recovery and persistence. This project will benefit the 1 in 20 Australian children who stutter and their families. We will learn for the first time how stuttering impacts on child development in the early school years and document the relationship between stuttering and other childhood conditions. The study will produce much needed information about recovery from stuttering and stuttering persistence. Therefore new knowledge will result to inform the scientific community and provide professionals and families with much needed evidence-based information about stuttering progression. Together this information will inform intervention approaches and help direct resources to those children who need them most. Read moreRead less
Communication outcomes of preterm children: prevalence, description and intervention. Premature birth places children at risk of major disability, yet the majority of children are considered neurologically normal and disability free. However in follow-up studies at school age, preterm children are found to have lower verbal and nonverbal abilities that affects their academic and social development. Preterm children are six times more likely to require special educational support. This investigat ....Communication outcomes of preterm children: prevalence, description and intervention. Premature birth places children at risk of major disability, yet the majority of children are considered neurologically normal and disability free. However in follow-up studies at school age, preterm children are found to have lower verbal and nonverbal abilities that affects their academic and social development. Preterm children are six times more likely to require special educational support. This investigation will examine the communication skills, cognitive processes and academic progress of children born preterm. The findings will provide an evidence base for decisions about monitoring and intervention of preterm infants at greater risk for poorer speech-language and academic outcomes.Read moreRead less
The language abilities of young offenders: Missing links in theory and practice.. Young offenders are a complex and challenging population, with high rates of comorbidity between attentional, learning, and behaviour problems. Few workers have, however, considered the underlying language processing and production skills in this population. Available evidence indicates a high level of vulnerability to language disorders in young offenders. These may contribute to poor academic performance and fail ....The language abilities of young offenders: Missing links in theory and practice.. Young offenders are a complex and challenging population, with high rates of comorbidity between attentional, learning, and behaviour problems. Few workers have, however, considered the underlying language processing and production skills in this population. Available evidence indicates a high level of vulnerability to language disorders in young offenders. These may contribute to poor academic performance and failure to develop prosocial skills. This study will explore language competencies and will describe their relationship to social skills, patterns of comorbidity, and type of offence (property Vs violent). Findings will be relevant to theories of juvenile offending and design of prevention/intervention programsRead 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
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.
Physiological, bahavioural and functional motor abilities in children with undifferentiated tongue movements during speech. A subgroup of children with speech disorders who have difficulty moving parts of their tongue independently during speech has been identified. This study aims to investigate if this is a unique phenomenon of the tongue during speech, or indicative of more generalized patterns of motor movement. This will enable us to explore the similarities between patterns of movement in ....Physiological, bahavioural and functional motor abilities in children with undifferentiated tongue movements during speech. A subgroup of children with speech disorders who have difficulty moving parts of their tongue independently during speech has been identified. This study aims to investigate if this is a unique phenomenon of the tongue during speech, or indicative of more generalized patterns of motor movement. This will enable us to explore the similarities between patterns of movement in the articulators during speech and non-speech tasks and the upper limb. In turn, this will inform the debate about motor control mechanisms for speech and other body movements, which would lead to more effective treatment regimes.Read moreRead less
