We have investigated the role of ageing on multisensory processes using a range of different tasks including speech perception and event perception. In our recent work, we are collaborating with the TILDA study (The Irish Longitudinal Study on Ageing), which is a large-scale, nationally representative, longitudinal study of ageing in Ireland. TILDA involves the collection of social, lifestyle, economic, health, physiological, cognitive and neuroimaging data from a large cohort of older adults (8,500+ participants). Data collection commenced in 2009 and is currently (2021) on its sixth wave of testing.
Our current research project is funded by the Health Research Board, in collaboration with Dr. Annalisa Setti, University College Cork and Prof. Ladan Shams, University of California Los Angeles, and is aimed at providing a better understanding of the role of ageing on multisensory perception.
What are we examining?
We use the Sound Induced Flash Illusion (or SIFI; Shams et al., 2000, 2002) to examine multisensory perception in ageing. SIFI is a well-established measure of audio-visual integration.
