Title: Multisensory interactions between olfaction and vision: The influence of odours on visual perception and attention
Abstract: In day-to-day life, our brains constantly integrate information from the different senses in order to perceive the world around us. For example, integration of vision, smell, taste, touch and sound is important for “flavour” perception during eating. Multisensory interactions between olfaction and vision are poorly understood, yet countless examples of olfactory-visual integration are available, such as the strong and robust associations between odours and colours. In this talk, I will describe a series of studies investigating how odours influence facets of visual attention and perception. In each study, participants were presented with odours and images that were either matching (e.g., orange odour and orange image) or non-matching (e.g., mint odour and orange image). Using behavioural paradigms, we found that odours heighten the salience of matching visual images at the limits of perceptual discrimination. EEG and fMRI techniques revealed that odours enhance the neural processing of matching visual images at an early stage of visual perception. Taken together, the results of these studies provide crucial new evidence for early interactions between olfaction and vision that significantly affect visual attention and perception. Notably, these effects are much larger in females than in males.
