The emotional psychology of blood donors: understanding and using the affective key to donor return. Every week in Australia 27,000 blood donations are required to meet medical needs. Though donors are continually recruited, each year around 40per cent of Australian donors fail to re-donate. Why this occurs and how to prevent this is not well understood. Using an approach grounded in psychology and affective science, this project comprises a program of studies that aims to advance understanding ....The emotional psychology of blood donors: understanding and using the affective key to donor return. Every week in Australia 27,000 blood donations are required to meet medical needs. Though donors are continually recruited, each year around 40per cent of Australian donors fail to re-donate. Why this occurs and how to prevent this is not well understood. Using an approach grounded in psychology and affective science, this project comprises a program of studies that aims to advance understanding of the affective factors that contribute to blood donor return and translate that understanding into interventions to increase donor return. The project aims to advance the psychological conceptualisation of blood donation by integrating insight from affective science, while also enabling the Blood Service to meet the nation's demand for blood products.Read moreRead less
How pain shapes our social world. Pain is an important source of human experience. Traditionally it has been defined by its social and psychological costs and treated as a problem that needs to be ‘fixed’. This project represents the first systematic study of the ways in which pain may motivate social and behavioural responses that serve to enhance affiliation, communication, solidarity, and group formation. In this way, pain may serve to connect people with their social worlds - it may act as s ....How pain shapes our social world. Pain is an important source of human experience. Traditionally it has been defined by its social and psychological costs and treated as a problem that needs to be ‘fixed’. This project represents the first systematic study of the ways in which pain may motivate social and behavioural responses that serve to enhance affiliation, communication, solidarity, and group formation. In this way, pain may serve to connect people with their social worlds - it may act as social glue - bringing people together and strengthening social connection. The findings will help to to provide a broader perspective on physical pain and will lead to insights that are important when treating pain.Read moreRead less
Functional impact of high fat and high sugar diets on memory encoding. This project aims to determine the functional mechanisms of how fats and sugar affect neuronal processes vital for learning and memory. Expected outcomes will define the neural mechanisms underpinning cognitive changes in emotional and spatial memory encoding, and how these relate to brain and metabolic parameters. This will provide benefits by unveiling the possible consequences of dietary fat and sugar on the brain, and th ....Functional impact of high fat and high sugar diets on memory encoding.

Summary
Does obesity alter the associations to food related cues, contexts and responses? Obesity is increasing dramatically in the developed world. The reasons for this are unclear, however the abundance of cheap, palatable food is clearly a contributing factor. Studies suggest differences arise in the processing of food rewards between overweight and lean individuals and the way they respond to food associated cues. This indicates that food associated cues may be more likely to evoke feeding behaviour ....Does obesity alter the associations to food related cues, contexts and responses? Obesity is increasing dramatically in the developed world. The reasons for this are unclear, however the abundance of cheap, palatable food is clearly a contributing factor. Studies suggest differences arise in the processing of food rewards between overweight and lean individuals and the way they respond to food associated cues. This indicates that food associated cues may be more likely to evoke feeding behaviours in absence of metabolic needs, therefore contributing to over eating that leads to obesity. This project will determine how rats, exposed to a model of our obesogenic western diet, process distinct cues and contexts associated with food rewards and control value driven responses to gain food rewards.Read moreRead less
Paving the way for ultra-long haul flights: strategies to mitigate jetlag. This project aims to develop and test strategies to mitigate jetlag, founded on biophysical modelling of circadian rhythms. It sets out to quantify the speed of circadian adaptation of sleep, alertness, and metabolism after transmeridian travel and to maximise speed of adaptation via optimised timing of light exposure, food, and exercise in-flight and on-the-ground. Expected outcomes include powerful models for jetlag str ....Paving the way for ultra-long haul flights: strategies to mitigate jetlag. This project aims to develop and test strategies to mitigate jetlag, founded on biophysical modelling of circadian rhythms. It sets out to quantify the speed of circadian adaptation of sleep, alertness, and metabolism after transmeridian travel and to maximise speed of adaptation via optimised timing of light exposure, food, and exercise in-flight and on-the-ground. Expected outcomes include powerful models for jetlag strategies, ready for application in air travel. The project will directly inform Qantas’ operations for ultra-long haul flights and their international network more broadly. Project outcomes will benefit society and the economy through improving travellers’ alertness, sleep, and reducing the risk of fatigue-related accidents.Read moreRead less
Mapping cognitive impulsivity through online testing. The project aims to develop a new model of cognitive impulsivity and produce an online tool to measure it. Impulsivity is defined as the skill/s that exert control over impulsive behaviours. It is a trait of human cognition that affects health and productivity and that varies normatively across the healthy population. However, coherent models of cognitive impulsivity and comprehensive measures of the construct are lacking. The project aims to ....Mapping cognitive impulsivity through online testing.

It is a trait of human cognition that affects health and productivity and that varies normatively across the healthy population. However, coherent models of cognitive impulsivity and comprehensive measures of the construct are lacking. The project aims to unravel and measure the cognitive skills that can produce (or avoid) impulsive behaviour.Read moreRead less
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
Self-control and pathologies of agency. This project will develop a philosophically and scientifically sophisticated account of the nature of self-control. This account will provide tools for allocating responsibility for failures of self-control and will contribute to the development of means for enhancing it, thereby aiding in addressing major social problems.
Detecting and tracking alertness using speech biometrics. Traditional tests for detecting and tracking alertness are limited by their accuracy and inability to be administered without stopping work. This project aims to investigate how speech can be used to monitor changes in performance resulting from sleep deprivation and successive night shifts. The expected outcomes are 1) new knowledge on how sensitive speech and language features are for detecting change in alertness, and 2) development an ....Detecting and tracking alertness using speech biometrics. Traditional tests for detecting and tracking alertness are limited by their accuracy and inability to be administered without stopping work. This project aims to investigate how speech can be used to monitor changes in performance resulting from sleep deprivation and successive night shifts. The expected outcomes are 1) new knowledge on how sensitive speech and language features are for detecting change in alertness, and 2) development and verification of a highly accurate, cost-effective, speech focussed assay capable of detecting impaired alertness from otherwise healthy individuals. The project should benefit the way fitness for duty is tested and provide new methods for safeguarding Australians working in at-risk environments.Read moreRead less

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
