Summary
Up to 50% of preterm infants will have one or more developmental difficulties. While medical complications are implicated in these problems, recent evidence points to the added effect of the infant's early environment. Hospitalised premature infants experience stress from necessary but painful hospital procedures, overstimulation and maternal deprivation. Evidence, largely from animal studies, suggests stressful early experience negatively affects brain development.

While medical complications are implicated in these problems, recent evidence points to the added effect of the infant's early environment. Hospitalised premature infants experience stress from necessary but painful hospital procedures, overstimulation and maternal deprivation. Evidence, largely from animal studies, suggests stressful early experience negatively affects brain development. We also know that premature infants find it difficult to handle stress as they are highly disorganised neurobehaviourally. The primary aim of this study is to assess the effectiveness of a parent-based intervention in enhancing neurobehavioural development at two years of age in very premature infants. It is predicted that this stress-reduction intervention will also enhance medical stability,normal brain development, parent-child interaction and parental mental health. The intervention to be trialled involves intensive training of parents of very premature infants, and in the 12 weeks following birth the parents will be the change agents. A randomised controlled trial comparing intervention and control groups will be undertaken to assess the effectiveness of this intervention. Assessments of early brain and 2 year intellectual, emotional and behavioural development will provide important outcome measures. A major strength of this study is the inclusion of advanced Magnetic Resonance Imaging (MRI) technology as it enables differences in brain development between the intervention and control group to be assessed, the association between brain and neurobehavioural development to be explored, and the impact of stress on early brain development to be investigated. This intervention is relatively simple and inexpensive, and would be a valuable contribution to neonatal care if found to be effective in enhancing brain and neurobehavioural development.Read moreRead less
Discovering genes for singing ability in Australian families. Music abilities are core to what makes us human, with singing ubiquitous in all cultures. Anecdotal evidence suggests that singing ability runs in families, supporting its genetic basis, however no research has systematically traced it across generations. Using an innovative web-based singing program and the latest molecular genetic techniques, this project aims to discover singing ability genes through the first Australian study of l ....Discovering genes for singing ability in Australian families. Music abilities are core to what makes us human, with singing ubiquitous in all cultures. Anecdotal evidence suggests that singing ability runs in families, supporting its genetic basis, however no research has systematically traced it across generations. Using an innovative web-based singing program and the latest molecular genetic techniques, this project aims to discover singing ability genes through the first Australian study of large families with many talented singers. This will generate new knowledge on the origins of human musicality and help Australia develop a sustainable source of cultural capital. It will build interdisciplinary research capacity and inform bespoke music learning programs that account for individual differences.Read moreRead less
The genetic basis of singing ability. This project aims to explore the heritability of music ability, focusing on singing and the contribution of genetic and environmental influences. Research suggests that deliberate practice (more than 10,000 hours) produces skilled musicianship, with minimal investigation of genetic influences. Mapping the human genome has opened up a new scientific frontier, and this project’s findings are expected to lead to the discovery of genes for singing. This will hel ....The genetic basis of singing ability.

Research suggests that deliberate practice (more than 10,000 hours) produces skilled musicianship, with minimal investigation of genetic influences. Mapping the human genome has opened up a new scientific frontier, and this project’s findings are expected to lead to the discovery of genes for singing. This will help design and deliver music education programmes that take individual differences into account, differentiating between heritable aspects of musicianship and those more influenced by training.Read moreRead less
Understanding employee-employer relationships during bridge employment: A psychological contract perspective. Bridge employment (paid employment after retirement from a career job) has several advantages for the individual (financial benefits, feeling of social connectedness, sense of accomplishment), employing organisations (access to experienced and skilled workers), and the government (lower burden on pension and benefits schemes). The proposed research will study the employee-employer relati ....Understanding employee-employer relationships during bridge employment: A psychological contract perspective. Bridge employment (paid employment after retirement from a career job) has several advantages for the individual (financial benefits, feeling of social connectedness, sense of accomplishment), employing organisations (access to experienced and skilled workers), and the government (lower burden on pension and benefits schemes). The proposed research will study the employee-employer relationship in bridge employment, with a focus on their perceptions of mutual obligationsin form of the psychological contract. An understanding of the psychological contract will make it more likely that the employment relationship fulfils the needs of the employees and employers and leads to a more successful bridge employment relationship.Read moreRead less
Developing and evaluating a theoretically grounded novice driver education program incorporating simulators. Australian young drivers are 13 per cent of the population but account for nearly a quarter of road deaths.

Australian young drivers are 13 per cent of the population but account for nearly a quarter of road deaths. This project aims to develop a research informed, theory-driven education intervention that includes a simulator component to improve their driving skills and attitudes. A process and outcome evaluation aims to assess the effectiveness of the training including the impact on how individuals learn to drive, changes in skill and attitudes as well as the influence on crashes and offences. It is intended that a second parallel study will adapt the intervention for Indigenous Australians and examine the effectiveness of this adaptation.Read moreRead less
Testing a Multi-level Theory of Emotion in Organisations. Affective moods and emotions at work are now recognised internationally as important determinants of employee attitudes and behaviours at work, including job satisfaction, turnover, and performance.

Affective moods and emotions at work are now recognised internationally as important determinants of employee attitudes and behaviours at work, including job satisfaction, turnover, and performance. This collaborative project involves research teams in Australia and the United States, and entails three studies of the role of emotions in organisations. Based on experience-sampling methods, where participants report real-time data using hand-held computers, the studies span within-person, between-persons, leadership, group, and organisational levels of analysis. The project also extends previous research by studying organisations as a source of depletion of regulatory resources that limit employees' potential to perform to their ability.Read moreRead less
Integrity, Leadership and Behaviour in Organisations. Recent high profile corporate scandals such as those involving Enron and HIH have demonstrated how important it is for leaders and managers to demonstrate integrity in their actions. However, organisational researchers have struggled to reach agreement on the qualities of character and behaviour that define integrity. This work draws on work in the philosophical tradition to propose a new multidimensional conceptualisation of leader integri ....Integrity, Leadership and Behaviour in Organisations. Recent high profile corporate scandals such as those involving Enron and HIH have demonstrated how important it is for leaders and managers to demonstrate integrity in their actions. However, organisational researchers have struggled to reach agreement on the qualities of character and behaviour that define integrity. This work draws on work in the philosophical tradition to propose a new multidimensional conceptualisation of leader integrity and to develop a measurement instrument for its assessment. The influence of leader integrity on the behaviour of leaders and subordinates is explored, and a program aimed at enhancing integrity in organisational leadership developed and trialled.Read moreRead less

Overinvolved and overcontrolling parenting seems to be on the rise as families are confronted with an unsteady world. This project aims to investigate how overparenting affects youth's achievements and well-being as they transition out of secondary school, and will isolate societal and cultural determinants of overparenting. This project will generate new knowledge on family influences on youth's progress, and will substantially contribute to an existing multinational study to identify macro social-cultural determinants of overcontrolling parenting. Expected outcomes are the generation of new knowledge relevant to family policy and practice within Australia, growth in cross-national collaborations, and new theories and methods.Read moreRead less
The Disproportionate Impact of Negative Contact on Category Salience and Prejudice: Explaining Why Intergroup Interactions Can Be Harmful.

The social psychological literature suggests that face-to-face interactions between people of rival groups will reduce mutual prejudice and discrimination. The present research tests the novel prediction that negative face-to-face interactions have a greater probability of worsening broad intergroup relations than positive face-to-face interactions have of improving them. The research will benefit Australia by (a) explaining why intergroup conflict continues to be a key social issue in multicultural Australia despite increased intergroup interactions and by (b) informing policy makers about the social conditions that result in more conflicting intergroup relations as well as the social conditions that result in more harmonious relations.Read moreRead less
