Summary
Music and speech as a window into the predictive brain . Prediction is fundamental to daily life, and yet we know little about how this central process works in the brain. This research program aims to provide in-depth insight into predictive processing by investigating the precise, culturally relevant, and communicative domains of music and speech. The research expects to reveal cognitive and neural correlates of “what” will occur and “when” it will occur, while exploiting the musician brain as ....Music and speech as a window into the predictive brain . Prediction is fundamental to daily life, and yet we know little about how this central process works in the brain. This research program aims to provide in-depth insight into predictive processing by investigating the precise, culturally relevant, and communicative domains of music and speech. The research expects to reveal cognitive and neural correlates of “what” will occur and “when” it will occur, while exploiting the musician brain as a model for plasticity. Expected outcomes include a multi-dimensional model of prediction and its neural markers that will lay the foundation to investigate impaired predictive processing. This should substantially benefit health and education by providing perspectives for training and rehabilitation.Read moreRead less

Summary
How the brain creates a sense of auditory space. How the brain creates a sense of auditory space. Spatial hearing is necessary for locating the source of a sound, and critical for communication in noisy listening conditions. The object of this project is to determine how the mammalian brain, including in human listeners, represents sensitivity to interaural time differences, one of the two binaural cues, and how this representation is transformed from the brainstem to the cortex. Anticipated out ....How the brain creates a sense of auditory space. How the brain creates a sense of auditory space. Spatial hearing is necessary for locating the source of a sound, and critical for communication in noisy listening conditions. The object of this project is to determine how the mammalian brain, including in human listeners, represents sensitivity to interaural time differences, one of the two binaural cues, and how this representation is transformed from the brainstem to the cortex. Anticipated outcomes include a coherent model of binaural hearing that links cellular, systems and perceptual investigations, and an understanding of the human auditory brain that should facilitate novel technologies and interventions to improve hearing function.Read moreRead less
Investigating the characteristics of older adults' conversation behaviour. The project aims to determine the factors that negatively impact older adults’ ability to engage in conversation. This is an important health issue; conversations are essential for communicating needs and maintaining social links; reduced social engagement leads to serious health problems and anticipates cognitive decline. The project will compile profiles of older adults' auditory-visual conversation behavior and indices ....Investigating the characteristics of older adults' conversation behaviour. The project aims to determine the factors that negatively impact older adults’ ability to engage in conversation. This is an important health issue; conversations are essential for communicating needs and maintaining social links; reduced social engagement leads to serious health problems and anticipates cognitive decline. The project will compile profiles of older adults' auditory-visual conversation behavior and indices of perceptual, cognitive and social skills. A path model will link these data to ratings of social engagement and satisfaction. By identifying factors leading to low ranked conversations, evidence-based guidelines can be developed for older adults and their carers to enhance communication and improve health and well-being.Read moreRead less
Contextual modulation in high-level vision. This project aims to understand the nature and mechanisms of spatial contextual modulation and the relationship between spatial and temporal context. Contextual modulation refers to the sometimes profound changes in the appearance of the visual image caused by interactions across space and time. Little work has been done to examine whether spatial context effects exist for high-level attributes of objects, and socially relevant stimuli such as heads an ....Contextual modulation in high-level vision. This project aims to understand the nature and mechanisms of spatial contextual modulation and the relationship between spatial and temporal context. Contextual modulation refers to the sometimes profound changes in the appearance of the visual image caused by interactions across space and time. Little work has been done to examine whether spatial context effects exist for high-level attributes of objects, and socially relevant stimuli such as heads and bodies. This project expects to provide new knowledge regarding the way that contextual modulation is mediated by interactions within the normal human visual system. This will provide significant societal benefits as contextual interactions in sensory processing can have profound consequences for our perceptual experience.Read moreRead less

Understanding the neural dynamics of colour constancy and feature binding. A key open question in visual neuroscience is how sensory input is combined with higher-level influences (e.g. attentional state). This project aims to address this using neuroimaging techniques combined with sophisticated analysis methods that were recently developed to measure when stimulus-related information is being transferred between different brain regions.

A key open question in visual neuroscience is how sensory input is combined with higher-level influences (e.g. attentional state). This project aims to address this using neuroimaging techniques combined with sophisticated analysis methods that were recently developed to measure when stimulus-related information is being transferred between different brain regions. These methods will be used to investigate the neural mechanisms underlying two fundamental phenomena in visual perception: feature binding and colour constancy. Understanding the neural mechanisms by which sensory input interacts with attention for these tasks would be a major advance in understanding how interactions between brain regions give rise to our perceptual experiences.Read moreRead less

A crucial question in cognitive neuroscience regards how humans integrate perceptual information to understand and interact with our environment. This project aims to identify neural processes that operate competitively and cooperatively within the left and right hemispheres to understand how the human brain integrates information for perception. This project expects to generate new insight into the nature of hemispheric communication and perceptual decision making. This should provide significant benefits by understanding how the two brain hemispheres process different visual information yet communicate efficiently to allow seamless interface with the world.Read moreRead less
From sensation to aesthetic appreciation. This project aims to understand the perceptual foundations of aesthetics. The experience of beauty is among the most compelling aspects of our interaction with the world but understanding aesthetic appreciation is difficult, because aesthetic experience varies between individuals, and is assumed to be influenced by culture, context and taste. In contrast, this project offers an account of aesthetic experience which connects the aesthetic object, the perc ....From sensation to aesthetic appreciation. This project aims to understand the perceptual foundations of aesthetics. The experience of beauty is among the most compelling aspects of our interaction with the world but understanding aesthetic appreciation is difficult, because aesthetic experience varies between individuals, and is assumed to be influenced by culture, context and taste. In contrast, this project offers an account of aesthetic experience which connects the aesthetic object, the perceptual processing of its properties and the resulting affective responses. Outcomes from this project will have potential applications in creative settings from design of pleasing visual surroundings to user experience and advertising.Read moreRead less
Multisensory perception in active observers. Perception and action are usually studied separately, often under limited, non-ecological conditions. Recent evidence shows both functions are intrinsically linked and mutually influence each other. This project exploits new technologies to study dynamic perception in free-moving observers in real and virtual multisensory environments. The project will establish the mechanisms underlying the perception/action link and reveal how perceptual stability i ....Multisensory perception in active observers. Perception and action are usually studied separately, often under limited, non-ecological conditions. Recent evidence shows both functions are intrinsically linked and mutually influence each other. This project exploits new technologies to study dynamic perception in free-moving observers in real and virtual multisensory environments. The project will establish the mechanisms underlying the perception/action link and reveal how perceptual stability is achieved despite dynamic input that changes with action. It will generate new understanding of how the brain integrates its twin functions of perceiving the multisensory world and acting upon it, and will generate useful knowledge for virtual, remote and robotic applications.Read moreRead less
