The “neurodante project”: Neurometric measurements of participant’s reaction to literary auditory stimuli from dante’s “divina commedia”

Abstract

This work is a pilot study that used neurometric indexes during the listening of selected pieces of Dante’s “Divina Commedia” in 20 participants. Half of them had a literary formation (Humanist; university students of literature) while the other half of is attending other university courses (Not Humanist). The study applied the electroencephalographic (EEG) rhythms variations, the heart rate (HR) and galvanic skin response (GSR) during the listening of the excerpts. The neurometric indexes here employed were the Approach Withdrawal (AW), the Cerebral Effort (CE) and the Emotional indexes (EI). Results for the comparisons of the estimated AW, CE and EI related to the perception of the canticas showed as the Humanist group reported higher AW and EI values when compared to the Not Humanist sample (p < 0.03 and p < 0.01, respectively). Results suggest that the perception of the aesthetic experience is significantly modulated by the previous specific knowledge experienced by the participants. Finally, results of this kind of research could find application in the implementation of software and devices based on symbiotic relation with the perspective reader or listener of a literature opera, in order to personalize and maximize the fruition of them.
