Summary
New directions for using brain stimulation to understand brain function. Neuroplasticity is of fundamental importance to brain function as it mediates learning, memory and development. Deficits in neuroplasticity are observed in a number of neurological conditions and thought to contribute to cognitive dysfunction. This study is designed to develop a better understanding of the neurochemical and genetic factors impacting on neuroplasticity. In addition, it aims to (i) upregulate brain connectivi ....New directions for using brain stimulation to understand brain function. Neuroplasticity is of fundamental importance to brain function as it mediates learning, memory and development. Deficits in neuroplasticity are observed in a number of neurological conditions and thought to contribute to cognitive dysfunction. This study is designed to develop a better understanding of the neurochemical and genetic factors impacting on neuroplasticity. In addition, it aims to (i) upregulate brain connectivity in a precise and targeted manner, (ii) elicit functional increases in cognitive performance and (iii) demonstrate the relationship between functional connectivity and cognition. Outcomes include a better understanding of plasticity in the brain & a enhanced capacity to examine and modulate brain plasticity.Read moreRead less
What is the functional significance of mirror neurons? Contrasting the adaptation and association models of the mirror neuron system. Mirror neurons are a type of brain cell that are thought to underlie empathy and cause autism. Alternatively, however, mirror neurons might instead arise from repeated associations between what we see and what we do. This study uses brain stimulation and neuroimaging techniques to determine the function of mirror neurons.
Multimodal testing for a fast subcortical route for salient visual stimuli. This project aims to uncover links between underlying brain circuitry, uncertainty and consciousness, and perceptions of fear. The project will use a multi-modal combination of brain imaging and neural recording techniques to generate new knowledge about the brain’s processing of biologically relevant information. The expected outcomes will enhance our knowledge of how the brain rapidly and non-consciously prepares the ....Multimodal testing for a fast subcortical route for salient visual stimuli. This project aims to uncover links between underlying brain circuitry, uncertainty and consciousness, and perceptions of fear. The project will use a multi-modal combination of brain imaging and neural recording techniques to generate new knowledge about the brain’s processing of biologically relevant information. The expected outcomes will enhance our knowledge of how the brain rapidly and non-consciously prepares the body for potential escape behaviours and of the brain pathways engaged in fear perception. The outcomes have the potential to inform strategies for overcoming anxiety and its effects on daily life, social interactions and workplace productivity.Read moreRead less
Pathways to social cohesion and social change: opinion-based groups and the dynamic formation of identities. This project will update the understanding of political conflict by exploring groups based around shared opinions. It will show that groups are likely to be more successful in their political campaigns when they tie their causes to national and other positive identifies.
Paving the way for effective public health interventions for bulimic eating disorders: Understanding stigma and mental health literacy. This research contributes to promoting and maintaining good health. The burden of bulimic eating disorders in the community is high, frequently ignored and increasing. Our research will pave the way for improved understanding of eating disorders and a reduction of stigma in relation to these problems. In so doing, it will lead to reduced shame and suffering for ....Paving the way for effective public health interventions for bulimic eating disorders: Understanding stigma and mental health literacy. This research contributes to promoting and maintaining good health. The burden of bulimic eating disorders in the community is high, frequently ignored and increasing. Our research will pave the way for improved understanding of eating disorders and a reduction of stigma in relation to these problems. In so doing, it will lead to reduced shame and suffering for people with eating disorders and enhance appropriate treatment seeking and the quality of advice received from family, friends and health professionals. A public health intervention based on our findings will contribute to a more tolerant and understanding community.Read moreRead less
When Targets Seek to Disconfirm Expectations: Possible Future Interactions and Target Awareness as Moderators of the Self-Fulfilling Prophecy. The self-fulfilling prophecy has been demonstrated in a series of experimental studies in which "perceivers" are led to hold erroneous expectations about "targets" with whom they interact and subsequently come to believe that targets have confirmed their expectations (perceptual confirmation). Objective raters have demonstrated that targets often do confi ....When Targets Seek to Disconfirm Expectations: Possible Future Interactions and Target Awareness as Moderators of the Self-Fulfilling Prophecy. The self-fulfilling prophecy has been demonstrated in a series of experimental studies in which "perceivers" are led to hold erroneous expectations about "targets" with whom they interact and subsequently come to believe that targets have confirmed their expectations (perceptual confirmation). Objective raters have demonstrated that targets often do confirm expectations with their actions (behavioural confirmation). However, targets do not always succumb to perceivers' expectations. The research proposed here seeks to examine the active role that targets may take in creating confirmation or disconfirmation by adding a temporal context to interactions, making targets aware of expectations, and manipulating properties of expectations.Read moreRead less
Cannabis and the brain: the good, the bad and the unknown. Cannabis is the most widely used illicit drug but much remains unknown about how it affects the brain. This research will examine effects on brain cells through to whole brain function in humans to determine how cannabis use may lead to impaired thinking or psychological symptoms and why cannabis might affect individuals in different ways.
Neural network underlying memory erasure. Memory expression can easily be reduced through the process of extinction, which involves repeated presentations of cues involved in that memory but without any outcome. In adult animals (including humans), it is widely accepted that extinction leads to a temporary inhibition of the original memory that remains largely unaltered. Remarkably, extinction causes erasure in juvenile rodents so that the original memory is permanently reduced. This is because ....Neural network underlying memory erasure. Memory expression can easily be reduced through the process of extinction, which involves repeated presentations of cues involved in that memory but without any outcome. In adult animals (including humans), it is widely accepted that extinction leads to a temporary inhibition of the original memory that remains largely unaltered. Remarkably, extinction causes erasure in juvenile rodents so that the original memory is permanently reduced. This is because the normal maturational changes in the brain result in fundamental developmental differences in the neural network underlying extinction. This project aims to map out this network across life, and also to reproduce the juvenile network in adult rats to erase memories via extinction in adulthood.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.

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
Collective Self-Regulation in Complex Social-Ecological Systems. This project plans to investigate the necessary supports and drivers for self-regulation for environmental purposes.

This project plans to investigate the necessary supports and drivers for self-regulation for environmental purposes. Sustainable human uses of natural resources are central to meeting contemporary challenges to humanity such as deforestation and climate change. However, the complexity of the social and ecological interdependences tests the human capacity for collective self-regulation – ordinary citizens’ regulation of their own behaviours for a greater good. The project aims to investigate the importance of establishing a common ground for collective self-regulation, the process of common ground formation in complex social-ecological systems, and how best to achieve this critical condition for sustainable ecological practices with a view to informing public discourse and policy-making for sustainable living.Read moreRead less
