Abstract
As Ss performed a tone detection task, background noise was reduced at possible signal presentation times. When a light stimulus intensified at those times, detectability of the tonal signal was higher than with a “dimming,” or a constant light. The magnitude of intersensory facilitation was less than for experiments without acoustic time specification reported earlier.
