The Life Scientific: Julia Simner

Synaesthesia is a merging of the senses, where words have tastes and letters have colours. Professor Julia Simner tests Jim in the studio with surprising results.

Imagine if you were listening to an opera or a Taylor Swift concert, and as the lights in the auditorium dimmed, the music was accompanied by a rainbow of colours only you could see. Perhaps while listening to your friends talking, you simultaneously experience a smorgasbord of tastes, with different words evoking different flavours, maybe a delicious ice cream, or something as disgusting as ear wax...
This merging of the senses is known as synaesthesia, and it鈥檚 the rich research world of neuropsychologist Professor Julia Simner. Julia runs the Multisense lab at the University of Sussex and has pioneered research into understanding how special brains process our sensory world in special ways. In the studio she tests Jim to see if he might be a synaesthete or have aphantasia, which is the inability to view images in the mind鈥檚 eye. The results are surprising.
Julia鈥檚 discovered links to autism, and to different personality types, as well as a number of previously unknown sensory differences.
She describes her career and her life as a series of swerves, or sliding door moments, that have led her to study the subject and the people she鈥檚 passionate about. She says that the more she looks for these unusual traits in us the more she finds.
