Circadian photoreceptor sensitivity and impacts of modern lighting on sleep. Light has powerful non-visual effects, including effects on sleep. These non-visual effects are mediated by cells in the eye that are most sensitive to blue light. There are large individual differences in sensitivity to non-visual effects of light that are not understood and that would give great insight into suboptimal sleep, which has become widespread in modern society. This study will be the first systematic examin ....Circadian photoreceptor sensitivity and impacts of modern lighting on sleep. Light has powerful non-visual effects, including effects on sleep. These non-visual effects are mediated by cells in the eye that are most sensitive to blue light. There are large individual differences in sensitivity to non-visual effects of light that are not understood and that would give great insight into suboptimal sleep, which has become widespread in modern society. This study will be the first systematic examination of individual differences in the effect of blue light on sleep and will uncover how alterations in the gene responsible for the effects of blue light on sleep (OPN4) contribute to these differences. This will lead to scalable individualised solutions to the unmet problem of how modern light environments impact sleep.Read moreRead less
Hunger flexibly modifies hypothalamic neural circuits responding to threat. Animal and human behaviour frequently involves a choice between actions or goals with conflicting positive and negative outcomes. However, the appropriate action or goal in conflicting situations often depends on physiological pressures like hunger, stress and mating opportunities. For example, the need for resources within an environment, such as food, drives approach behaviour, whereas threats to survival, such as pred ....Hunger flexibly modifies hypothalamic neural circuits responding to threat. Animal and human behaviour frequently involves a choice between actions or goals with conflicting positive and negative outcomes. However, the appropriate action or goal in conflicting situations often depends on physiological pressures like hunger, stress and mating opportunities. For example, the need for resources within an environment, such as food, drives approach behaviour, whereas threats to survival, such as predator cues, enhance avoidance behaviour. This project will uncover the neural circuitry and endocrine mechanisms through which hunger influences hypothalamic threat-detecting circuits that suppress food intake. These studies provide a new hypothalamic model to understand risk/reward decision in the brain.Read moreRead less
Evaluating the Quality of Scientific Research in Psychology. Buttressing public trust in science has never been more important, yet many sciences are experiencing a crisis of confidence. The current system of relying on journal prestige to calibrate our confidence in individual research findings has created corrupt incentives for scientists, and risks undermining public trust in science. Thousands of scientists and institutions around the world have indicated that research evaluation needs an ov ....Evaluating the Quality of Scientific Research in Psychology. Buttressing public trust in science has never been more important, yet many sciences are experiencing a crisis of confidence. The current system of relying on journal prestige to calibrate our confidence in individual research findings has created corrupt incentives for scientists, and risks undermining public trust in science. Thousands of scientists and institutions around the world have indicated that research evaluation needs an overhaul by signing the Declaration on Research Assessment. One solution is to create a public, transparent, and valid process for producing and sharing expert evaluations of individual papers. This project aims to launch this reform in psychology, and partner with PREreview to help it spread to other fields.Read moreRead less
The impact of female sex hormones on neurodevelopment. This project aims to characterise the contribution of sex hormones to the development of emotional brain circuits in female adolescents. Puberty is associated with profound changes in emotional behaviours in females, but we know little about the underlying brain mechanisms. In particular, research has neglected to consider the role of the sex hormones for which changes are a defining feature of female puberty (eg, oestradiol). This work will ....The impact of female sex hormones on neurodevelopment. This project aims to characterise the contribution of sex hormones to the development of emotional brain circuits in female adolescents. Puberty is associated with profound changes in emotional behaviours in females, but we know little about the underlying brain mechanisms. In particular, research has neglected to consider the role of the sex hormones for which changes are a defining feature of female puberty (eg, oestradiol). This work will be the first to comprehensively advance our understanding of the unique role of sex hormones in shaping the adolescent female brain. It will provide critical understanding of how individual differences in hormonal factors increase risk for emotional problems in females, and inform treatment strategies.Read moreRead less
Testing an Integrative Model of Interpersonal Partner Aggression. The project aims to conduct: 1) a developmental test (i.e., from childhood to adulthood), and 2) a dyadic longitudinal test of an integrative model of intimate partner violence (IPV). The project is significant as it addresses 4 key IPV research limitations. These are the lack of: 1) focus on relationship dynamics; 2) longitudinal research on couples; 3) developmental tests of IPV; 4) research on same-sex couples. Expected outcome ....Testing an Integrative Model of Interpersonal Partner Aggression. The project aims to conduct: 1) a developmental test (i.e., from childhood to adulthood), and 2) a dyadic longitudinal test of an integrative model of intimate partner violence (IPV). The project is significant as it addresses 4 key IPV research limitations. These are the lack of: 1) focus on relationship dynamics; 2) longitudinal research on couples; 3) developmental tests of IPV; 4) research on same-sex couples. Expected outcomes include a comprehensive suite of assessments to effectively detect and support couples at risk of IPV and self-help resources to combat IPV. Benefits include the development of an integrative framework to identify couples most at risk of IPV and guide the development of interventions and policy to reduce IPV.Read moreRead less
How childhood inattention affects the emerging cognitive landscape. This project aims to determine whether behavioural and cognitive inattention differentially map onto early and later developing cognitive skills such as numeracy and literacy. Lack of focus and concentration, distractibility, poor task completion and forgetfulness are common manifestations of inattention and can insidiously affect learning skills that need attention as a building block such as literacy and numeracy skills. Howev ....How childhood inattention affects the emerging cognitive landscape. This project aims to determine whether behavioural and cognitive inattention differentially map onto early and later developing cognitive skills such as numeracy and literacy. Lack of focus and concentration, distractibility, poor task completion and forgetfulness are common manifestations of inattention and can insidiously affect learning skills that need attention as a building block such as literacy and numeracy skills. However, how attention affects their acquisition, across development, is not fully known. The findings are expected to guide cognitive-based interventions to improve attention skills as a mechanism for improving children’s learning trajectories in the first years of schooling.Read moreRead less
Enhancing Australia's Social Connectedness and Emotional Well-being. This project aims to redefine scientific understanding of why social connections are good for well-being, conceptualizing it as a process that involves successful regulation of emotions and behaviour. Effective social interventions require precise understanding of psychological process: the project will supply this understanding and leverage it to develop evidence-based interventions that grow social and emotional skills. Expec ....Enhancing Australia's Social Connectedness and Emotional Well-being. This project aims to redefine scientific understanding of why social connections are good for well-being, conceptualizing it as a process that involves successful regulation of emotions and behaviour. Effective social interventions require precise understanding of psychological process: the project will supply this understanding and leverage it to develop evidence-based interventions that grow social and emotional skills. Expected outcomes include generation of a novel literature at the intersection of social- and self-regulation and methodological innovations in the study of social connections. Significant benefits include creation of applied interventions with the potential to provide a ‘social cure’ for Australia’s loneliness problem.Read moreRead less
Building trust and sustainability by promoting a moral frame to nature. The collective benefits of sustainable behaviour tend to be abstract and less obvious compared to the immediate benefits of self-interest. This project aims to examine an avenue through which to make these benefits more concrete and personal – by providing a moral frame to nature. The studies aim to explore how this may be achieved, the socio-ecological factors that might limit such attempts, and the downstream implications ....Building trust and sustainability by promoting a moral frame to nature. The collective benefits of sustainable behaviour tend to be abstract and less obvious compared to the immediate benefits of self-interest. This project aims to examine an avenue through which to make these benefits more concrete and personal – by providing a moral frame to nature. The studies aim to explore how this may be achieved, the socio-ecological factors that might limit such attempts, and the downstream implications for generalised trust and cooperation amongst human groups. We expect the findings will offer insight into an important avenue through which we can leverage human cooperation and trust and promote the value of the common good. Read moreRead less
