The Role of Multisensory Processes in Incidences of Falls and Cognitive Decline in Ageing – (Ph.D.)

Most research in human perception has dealt with each of the senses in a separate manner, and research typically takes a 'reconstructive' approach to each system. However, recognition tasks and spatial localisation in the real world is rarely based on one modality only and involves a complex interplay between all the modalities.

Research findings have suggested that efficient cross-sensory integration declines with old age and is particularly inefficient in older persons who are prone to falling. The proposed research will involve a systematic investigation of multisensory processes and how ageing may effect the efficient sharing of information across the senses.

One important goal of this project is to devise a set of assessment tools that mark the onset of decline in posture control (leading to falls) and in other higher cognitive functions. Finally, the research will help guide in the design of intervention technologies designed to prevent falls and cognitive decline in older persons.
