Hippocampal regulation of goal-directed decision-making. The hippocampus is a part of the brain that is central to learning and memory yet little is known about its role in decision-making. It is the aim of this application to provide the first detailed, causal evidence of hippocampal regulation of decision-making. This is significant because many mental health disorders and dementias that involve decision-making deficits are characterised by hippocampal dysfunction, but any direct link between ....Hippocampal regulation of goal-directed decision-making. The hippocampus is a part of the brain that is central to learning and memory yet little is known about its role in decision-making. It is the aim of this application to provide the first detailed, causal evidence of hippocampal regulation of decision-making. This is significant because many mental health disorders and dementias that involve decision-making deficits are characterised by hippocampal dysfunction, but any direct link between these factors is unknown. The outcomes of the current grant will provide the first evidence of that link, thus providing deeper understanding of the neurophysiological mechanisms of these disorders, which could eventuate in the creation of more beneficial treatments.

Refugee moral injury: Linking interpersonal trauma and social functioning. This project aims to understand how moral beliefs about past interpersonal traumatic experiences (e.g., torture, rape) are associated with social outcomes considered to be crucial in successful refugee resettlement. This project will investigate the causal impact of these moral beliefs on social adaptation and whether these beliefs are malleable. The project will be a better understanding of how moral beliefs can impact r ....Refugee moral injury: Linking interpersonal trauma and social functioning. This project aims to understand how moral beliefs about past interpersonal traumatic experiences (e.g., torture, rape) are associated with social outcomes considered to be crucial in successful refugee resettlement. This project will investigate the causal impact of these moral beliefs on social adaptation and whether these beliefs are malleable. The project will be a better understanding of how moral beliefs can impact refugees' abilities to navigate and engage with novel social environments. The outcomes of this project will assist service providers and policy makers to understand why some refugees are able to adapt more successfully than others and provide practical tools for improving social outcomes.

Whether social media literacy mitigates effects of social media in adolescents. This project aims to determine protective and risk factors for problems associated with social media use in early adolescents. In particular, it aims to determine the protective role of social media literacy (the skill to analyse, critique and evaluate social media posts). Although most Australian adolescents use social media, frequent social media engagement and photo-based activities can cause body dissatisfaction, ....Whether social media literacy mitigates effects of social media in adolescents. This project aims to determine protective and risk factors for problems associated with social media use in early adolescents. In particular, it aims to determine the protective role of social media literacy (the skill to analyse, critique and evaluate social media posts). Although most Australian adolescents use social media, frequent social media engagement and photo-based activities can cause body dissatisfaction, disordered eating and compromised well-being. Findings supporting a protective role for social media literacy are expected to inform policy to improve adolescent well-being and pave the way for school-based social media literacy interventions.Read moreRead less
The cost of keeping gruesome images from the world. This project aims to investigate one of society’s most invisible ‘frontline’ trauma workforces—the online content moderators responsible for limiting the public’s exposure to distressing and sensitive content on social media. Using a series of rigorous experiments, and cutting-edge psychological and physiological assessment techniques, the research will advance our understanding of the impact of indirect trauma on mental health.

This project aims to investigate one of society’s most invisible ‘frontline’ trauma workforces—the online content moderators responsible for limiting the public’s exposure to distressing and sensitive content on social media. Using a series of rigorous experiments, and cutting-edge psychological and physiological assessment techniques, the research will advance our understanding of the impact of indirect trauma on mental health. Expected outcomes include novel empirical evidence for preventative strategies that will predict, monitor and reduce negative mental health outcomes. This will provide significant global benefits to people with indirect trauma experiences, such as defence and forensic personnel.Read moreRead less

The cognitive basis of anxiety-linked heightened negative expectancies. Problems with anxiety tear at the social and economic fabric of our nation. Individuals with an elevated vulnerability to experience high levels of anxiety display a heightened tendency to expect that the future will be emotionally negative.

Problems with anxiety tear at the social and economic fabric of our nation. Individuals with an elevated vulnerability to experience high levels of anxiety display a heightened tendency to expect that the future will be emotionally negative. The current project will test compelling new hypotheses concerning the cognitive mechanisms that causally underpin such negative expectancies, using cutting-edge cognitive methodologies that permit not only the sensitive assessment, but also the direct manipulation, of these mechanisms. The findings generated will exert major scientific impact, and will directly contribute to our national strategic efforts to improve the mental well-being of our citizens, and to build healthy and resilient communities.Read moreRead less

Differentiating the cognitive basis of unproductive versus productive worry. This project aims to delineate the individual differences in cognitive functioning that distinguish between the tendency to experience unproductive versus productive worry.

This project aims to delineate the individual differences in cognitive functioning that distinguish between the tendency to experience unproductive versus productive worry. For some people, worry severely compromises well-being, while for others worry yields significant benefits by fostering preparatory behaviours that protect against misfortune. Using innovative and compelling hypotheses, as well as laboratory and fieldwork approaches, this project will deliver the capacity to assess, predict, and explain the individual differences in unproductive and productive worrying that underpin variability in resilient responding to situations in which adaptive action can mitigate real-world risk. This project will have major scientific impact, generating influential publications concerning the cognitive distinctions between productive and unproductive worry that will position Australia as a global leader in this field.Read moreRead less

Body image concerns are a global public health issue with a devastating impact on key aspects of people’s lives. This project has the potential to inform the development of new ways to harness social media to support mental health and wellbeing.Read moreRead less
Determining the physical and temporal properties of a person's inner speech. Inner speech refers to the silent production of words in one's mind. While inner speech has long been assumed to be unquantifiable, we have recently demonstrated an ability to decipher the content a person's inner speech using an objective electrophysiological marker.

Inner speech refers to the silent production of words in one's mind. While inner speech has long been assumed to be unquantifiable, we have recently demonstrated an ability to decipher the content a person's inner speech using an objective electrophysiological marker. In this project, we will extend upon this work and use our marker to establish the physical and temporal properties of a person's inner speech, such as its loudness, pitch, accent and temporal properties. Our hope is that our modified marker will be capable of determining what a person is saying in inner speech, when they are engaged in inner speech, and also how their inner voice sounds. This work has major implications with regards to technology, health, and basic science. Read moreRead less

Exposure to adversity, such as violence, neglect and natural disasters, is common and a powerful risk factor for emotional maladjustment. Yet knowledge of the underlying mechanisms linking adversity with emotional maladjustment is remarkably limited. By drawing from theories of adversity and learning and utilising novel experimental methodology, this project aims to map how adverse experiences have different negative effects on daily emotional wellbeing by disrupting the mechanisms underlying how people learn to acquire and reduce reactivity to new threats. Expected benefits include new knowledge about the pathways linking adversity with psychopathology as well as the vital evidence-base for clear targets for behavioural interventions. Read moreRead less
