Research Abstract |
This study compared synchrony-asynchrony discrimination thresholds and the upper limits of temporal binding between audio-visual (AV), visuo-tactile (VT), and audio-tactile (AT) combinations. The results show that the temporal resolution of synchrony perception was similar for AV and VT (approximately 4 Hz), but significantly higher for AT (approximately 10 Hz). However, the upper limits of cross-attribute temporal binding were surprisingly similar for any combination of visual, auditory and tactile attributes (approximately 2.5 Hz). These findings suggest that cross-attribute temporal binding is mediated by a slow central process that combines separately processed 'what' and 'when' properties of a single event.
