The spatiotemporal characteristics of elementary audiovisual speech and music processing in musically untrained subjects

Abstract

Previously, the EEG technique has been used to investigate the spatiotemporal properties of audiovisual (AV) processing by taking advantage of the violation of the "additive model", which is considered to be a very conservative approach. In the present work, we used a less conservative and novel approach than the criterion of superadditivity for estimating AV interactions. Hence, we estimated AV interaction patterns by comparing the responses to AV stimuli with the averaged responses to the unimodal visual and auditory stimuli in musi Show more
