Left to right is front to back: attentional distortions in near and far space for healthy and clinical populations. We are investigating a perceptual bias that makes people think objects right in front of them are actually slightly to the right but objects far away are slightly to the left. This project will help understand why this happens, to help reduce traffic collisions and help people with brain damage that causes similar perceptual biases.
Attentional asymmetries for navigation in healthy and clinical groups. This project plans to investigate how differences in attentional capacity between the left and right sides of the brain affect the ability to walk or manoeuvre vehicles between obstacles. To navigate our environment and avoid obstacles, we need to attend to stimuli that are important and ignore those that are not. Unfortunately, the brain’s attentional capacity is limited, which can result in errors and collisions. Using the ....Attentional asymmetries for navigation in healthy and clinical groups. This project plans to investigate how differences in attentional capacity between the left and right sides of the brain affect the ability to walk or manoeuvre vehicles between obstacles. To navigate our environment and avoid obstacles, we need to attend to stimuli that are important and ignore those that are not. Unfortunately, the brain’s attentional capacity is limited, which can result in errors and collisions. Using the techniques of cognitive neuroscience, the project aims to provide a better understanding of the cognitive and neural mechanisms that govern attention in an applied setting. It expects to identify the factors that exacerbate lapses in attention and collisions. The effect of everyday impediments such as mobile phones, alcohol and fatigue will be investigated together with means of minimising these attentional lapses and improving safety.Read moreRead less

Summary
The ups and downs of visuospatial attention. The brain has a remarkable capacity to provide a coherent experience of the world by seamlessly integrating sights and sounds from different locations. It is only after brain damage, or when faced with a high attentional load, that our limitations become apparent. The project aims to investigate these limitations by determining how spatial location influences attention in relation to distractibility, cross-modal input and emotionality.

The brain has a remarkable capacity to provide a coherent experience of the world by seamlessly integrating sights and sounds from different locations. It is only after brain damage, or when faced with a high attentional load, that our limitations become apparent. The project aims to investigate these limitations by determining how spatial location influences attention in relation to distractibility, cross-modal input and emotionality. Eye tracking and physiological measures of arousal will be combined with traditional cognitive measures to provide a deeper understanding of spatial attention. This project aims to improve attentional models and develop innovative strategies to increase safety by decreasing inattention and distraction.Read moreRead less

Stroke patients cost the Australian economy $1.3bn pa in addition to their social burden, but effective diagnosis and rehabilitation is impeded by a lack of fundamental research into the cognitive and neural mechanisms that underlie attentional disorders. Our research will provide significant new insights into how the brain deploys attention in external and imagined space and will lead to more effective management and treatment of stroke victims. Our new test of attentional disorders is independent of a patient's inability to see or move and will enable more effective diagnosis. Our research provides the fundamental knowledge base for our discipline and is vital for developing the next generation of Australia's cognitive neuroscientists. Read moreRead less
