Abstract

Temporal synchrony is a critical condition for integrating information coming from different sensory modalities such as vision, audition and touch. However, how we take correspondence between the signals coming from different sensory modalities is still unclear. This paper first summarizes a series of psychophysical experiments on audio-visual temporal synchrony perception, conducted by us over the past several years (Fujisaki, Koene, Arnold, Johnston, & Nishida, 2006; Fujisaki & Nishida, 2005, 2007, 2008; Fujisaki, Shimojo, Kashino, & Nishida, 2004), and introduces our proposed model for audio-visual synchrony detection (Fujisaki & Nishida, 2005). The latter part of the paper introduces some of our more recent works on crossmodal temporal synchrony perception including tactile modality, which compare temporal frequency limits obtained with synchrony-asynchrony discrimination experiments between audio-tactile, visuo-tactile, and audio-visual stimulus pairs.
