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
Understanding the impact of missing family on forcibly displaced people. This project aims to investigate the psychological and social effects of having missing family on forcibly displaced people settled in Australia. This world-first project enlists a longitudinal mixed-method approach to compare those with missing family to those whose connections have been restored on key outcomes and coping strategies.

This project aims to investigate the psychological and social effects of having missing family on forcibly displaced people settled in Australia. This world-first project enlists a longitudinal mixed-method approach to compare those with missing family to those whose connections have been restored on key outcomes and coping strategies. Project outcomes will enhance the ability of Australian Red Cross and the International Committee of the Red Cross to understand and support the needs of families of the missing. This should provide significant practice and policy benefits for Red Cross’ humanitarian work in restoring family links in Australia and worldwide.Read moreRead less
The social and cognitive functions of affect. Dealing with affective problems represents a major challenge in clinical, health, organisational and counselling psychology. Yet the role that affective states play in thinking, judgments and many everyday social behaviours remains poorly understood..

Dealing with affective problems represents a major challenge in clinical, health, organisational and counselling psychology. Yet the role that affective states play in thinking, judgments and many everyday social behaviours remains poorly understood.. This project will produce direct national and community benefit by developing a new, integrative theory of affective influences on thinking and action, and exploring the functions and processing consequences of affect in everyday settings. The real-life consequences of affect infusion in applied areas will also be explored. The project will also contribute to Australia's research capability by training doctoral and postdoctoral students, and fostering international research collaboration.Read moreRead less

This project will inform the community about factors that affect the psychological, physical, academic, and employment outcomes of emerging adults. It will improve our knowledge of why some young people do not reach their full potential. The project will provide a comprehensive assessment of factors associated with well-being across several domains. It will better equip and assist professionals to identify early those youth at risk of having poor psychological, health, and employment prospects post-school. The project will inform the development of intervention programs for young people and maximise their overall adjustment and well-being several years later.Read moreRead less
The development of feedforward mechanisms of motor control: The role of efference copy in motor skill development. Our work provides preliminary evidence that deficits in efference copy (or feedforward planning) underlie impaired motor skill development in children (or Developmental Coordination Disorder - DCD). The aim of this project is to advance our understanding of normal and abnormal motor development by examining this hypothesis in a large sample, longitudinally. We will examine variati ....The development of feedforward mechanisms of motor control: The role of efference copy in motor skill development. Our work provides preliminary evidence that deficits in efference copy (or feedforward planning) underlie impaired motor skill development in children (or Developmental Coordination Disorder - DCD). The aim of this project is to advance our understanding of normal and abnormal motor development by examining this hypothesis in a large sample, longitudinally. We will examine variations in the presentation of clumsiness, cognitive deficit(s) in different subtypes, and changes in presentation with age. We predict that deficits in efference copy will explain departures from normal motor skill development in most children. We also predict that imagery training will ameliorate the deficit.Read moreRead less

The studies described in this project will provide important insights into the development of movement skill in children and the underlying causes of motor impairment. In particular we aim to understand how thought and action are coordinated in children, supporting the ability to perform more efficient movements. Hence, our work will inform the training and practice of movement educators and physical therapists, transcending some of the myths of clinical theory. This work will have important implications for identifying and training children at risk for motor impairment. Read moreRead less
A biopsychosocial model of exercise dependence, steroid use and disordered eating among adolescent boys. Recent evidence suggests that hazardous body change strategies adopted by adolescent boys are a major problem. This study validates a biopsychosocial framework to explain the development of exercise dependence, steroid and food supplement use, and disordered eating among at risk adolescent boys. A longitudinal experimental design will be employed.

Recent evidence suggests that hazardous body change strategies adopted by adolescent boys are a major problem. This study validates a biopsychosocial framework to explain the development of exercise dependence, steroid and food supplement use, and disordered eating among at risk adolescent boys. A longitudinal experimental design will be employed. Late maturing boys, who are also less popular with peers, are expected to demonstrate high body dissatisfaction, low self-esteem and high negative affect and maladaptive body change strategies. The result of this study will inform treatment programs for these behaviours.Read moreRead less
