This study examines how two sources of sensory information (vision and audition) interact to affect anticipatory judgements in an interception action task. Participants (n=12) predicted, by pressing a button, when a stimulus travelling at either a fast (224.13mm/s) or slow (113.49 mm/s) speed in a straight-line trajectory would enter a specified target zone. On each trial, the stimulus would disappear after either 33% or 66% of distance traveled from its start position. At the initiation of stimulus movement, a loud (70dB), soft (50db), or no (0db) burst of white noise was presented for 150 ms. Consistent with our hypotheses, Main Effects for stimulus Velocity (F(1,11)=1754.7, p.
