Common synaptic inputs to human upper airway muscles. Changes in the activity of upper airway muscles at sleep onset contribute to the development of Obstructive Sleep Apnoea. The aim of this project is to investigate how the brain controls upper airway muscles during wakefulness and sleep and to identify the pathological processes that lead to the development of Obstructive Sleep Apnoea.
Age and Gender Related Changes in Motor Control of the Upper Airway Muscle Genioglossus During Sleep. Obstructive Sleep Apnoea (OSA) is the repetitive obstruction of the airway during sleep. Obstructions occur because muscles of the upper airway fail to keep the airway open during inspiration. The disorder is associated with cardiovascular disease and cognitive and behavioural impairment. The prevalence of the disorder increases in older adults, contributing to age-related health and behavioural ....Age and Gender Related Changes in Motor Control of the Upper Airway Muscle Genioglossus During Sleep. Obstructive Sleep Apnoea (OSA) is the repetitive obstruction of the airway during sleep. Obstructions occur because muscles of the upper airway fail to keep the airway open during inspiration. The disorder is associated with cardiovascular disease and cognitive and behavioural impairment. The prevalence of the disorder increases in older adults, contributing to age-related health and behavioural problems. However, age-related changes differ in men and women. We believe the high prevalence of OSA in older adults is due to age and gender related changes in the activity of muscles in the upper airway. We will study the behaviour of the upper airway muscle genioglossus during sleep in young, middle-aged and older men and women.Read moreRead less
Cardiovascular and Respiratory Activity During Sleep Onset. Going to sleep requires that behavioural and physiological activities be modified. This is achieved by the integrated activity of sleep mechanisms and the circadian system. In this project we will investigate the nature of the regulatory control exerted by sleep mechanisms over respiration and cardiovascular activity at sleep onset, how sleep control interacts with circadian influence, and the nature of cardio-respiratory activity when ....Cardiovascular and Respiratory Activity During Sleep Onset. Going to sleep requires that behavioural and physiological activities be modified. This is achieved by the integrated activity of sleep mechanisms and the circadian system. In this project we will investigate the nature of the regulatory control exerted by sleep mechanisms over respiration and cardiovascular activity at sleep onset, how sleep control interacts with circadian influence, and the nature of cardio-respiratory activity when sleep control is removed at an arousal from sleep. It is anticipated that a better understanding of the regulatory control exerted by sleep over other systems will improve our understanding of sleep disorders.Read moreRead less
Respiratory and Cardiovascular Activation at Arousal from Sleep. An arousal from sleep, no matter how brief, is assciated with increased activity in the respiratory and cardiac systems. Under normal circumstances the response is considered adaptive. However, in disorders of sleep in which individuals arouse frequently and their sleep is fragmented, such as in Obstructive Sleep Apnea, the phenomenon has been linked to hypertension. While the clinical consequences of sleep fragmentation are now ap ....Respiratory and Cardiovascular Activation at Arousal from Sleep. An arousal from sleep, no matter how brief, is assciated with increased activity in the respiratory and cardiac systems. Under normal circumstances the response is considered adaptive. However, in disorders of sleep in which individuals arouse frequently and their sleep is fragmented, such as in Obstructive Sleep Apnea, the phenomenon has been linked to hypertension. While the clinical consequences of sleep fragmentation are now apparent, the mechanism that causes the increase in physiological activity at each arousal, is not known. The aim of this project will provide insight into the mechanism that produces the activation response and provide a basis for minimising the cardiac consequences of sleep disorders.Read moreRead less

When immigrants and converts are not truly one of us: Examining the social psychology and developmental antecedents of marginalizing racism. Marginalizing Racism, the simultaneous acceptance and rejection of others, is clearly present in Australia. It is not just a matter of thugs on the streets of Cronulla, but of elected politicians expressing Marginalizing Racist views. We believe that examining the social psychology and developmental causes of this insidious form of racism will pave the way ....When immigrants and converts are not truly one of us: Examining the social psychology and developmental antecedents of marginalizing racism. Marginalizing Racism, the simultaneous acceptance and rejection of others, is clearly present in Australia. It is not just a matter of thugs on the streets of Cronulla, but of elected politicians expressing Marginalizing Racist views. We believe that examining the social psychology and developmental causes of this insidious form of racism will pave the way for positive social change. This is not just an academic exercise, but a chance to expose and tackle a form of racism to which the broader public and our own profession appears to turn a blind eye. Moreover, as we expect this research to yield timely and influential discoveries, it will help maintain Australia's position as a world leader in the field of social psychology.Read moreRead less
Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessib ....Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessibility of captions, which is currently limited by English literacy, caption speed, and caption reduction techniques. Here, systematic manipulation of these factors in experiments on television captioning with adults and educational captioning with children will determine how resources might best be directed to improving caption accessibility.Read moreRead less
Children's Intergroup Prejudice: The Roles of Cognitive Representations and Self-presentation. Research indicates that intergroup prejudice remains a problem in most Australian schools. For example, children as young as 5-6 years assign negative attributes to indigenous Australians and Pacific Islander children, they prefer not to play with these children, and they do not even want them living nearby. The proposed research will examine the possible basis of age effects in these attitudes. It wi ....Children's Intergroup Prejudice: The Roles of Cognitive Representations and Self-presentation. Research indicates that intergroup prejudice remains a problem in most Australian schools. For example, children as young as 5-6 years assign negative attributes to indigenous Australians and Pacific Islander children, they prefer not to play with these children, and they do not even want them living nearby. The proposed research will examine the possible basis of age effects in these attitudes. It will have a substantial national benefit because it will increase our understanding of this insidious social phenomenon and provide a basis for developing an intervention that will minimise a problem that has the potential to devastate community relations.

Increasing our understanding of children's rejection sensitivity and its effects, as well as identifying the central processes involved, will contribute to a healthy start, preventative healthcare, and strengthening social and economic fabric. It will allow for a new intervention to build children's competencies, coping and resilience. This will protect from negative intrapersonal (e.g., depression) and interpersonal outcomes (e.g., loneliness, victimisation). It also will improve the social and learning contexts for students, benefit the environment in which teachers work, and strengthen the fabric of families and communities by contributing to the development of harmonious, cooperative environments.Read moreRead less
