Abstract:

Robust and versatile perception of the world is augmented considerably when information from our five separate sensory systems is combined. Much recent evidence has demonstrated near-optimal integration across senses, but it remains unclear at what level the integration occurs, at a "sensory" or "decisional" level. Here we show that non-informative "pedestal" motion stimuli in one sensory modality (vision or touch) selectively lowers thresholds in the other, to the same degree as pedestals in the same modality: strong evidence for functionally important cross-sensory integration at early levels of sensory processing.
