Non-Auditory Associations of Musical and Non-Musical Sounds in General Listeners

International Congress on Synaesthesia Art and Science V.
Our research explores theories based upon past behavioural studies and FMRI scans with Synaesthetes and general listeners. FMRI experiments have revealed that the cross-modal associations to sounds in Synaesthetes are less pronounced, yet still present in the general population. The results of our psycho-musicology study with 40 Synaesthetes and 40 non-Synaesthetes reveal a quasi-Synaesthetic [Nikolic, 2014] spectrum extending to general listeners, similar to culturally founded Synaesthesia [Kohler]. These findings engage theories regarding recruitment of brain pathways for specific sound stimuli, and draw attention to features in sound, which trigger specific strong associations in non-Synaesthetic individuals.
