Audio Visual Association Test in Non Synesthetic Subjects: Technological Tailoring of the Methods

Synesthesia is a relatively rare condition for which a specific stimulus activates one or more senses different from the ones usually designed for its evaluation; this can happen in any combination of senses or cognitive paths. In this work, we focus on audio-visual synesthesia, one of the most common. Many investigators have studied the connection between music and colours in synesthetic and non-synesthetic subjects in the past years, exploring the possibility of an emotional gate between the perception of these stimuli. In this study, an experiment was designed to verify whether this connection can be extended to music and images, considering not only colour but also shape and their spatial distribution. In the study, participants' musical and visual abilities will also be tested to explore any correlation with their music-images association.
