Fig 1.
Left: Kinematics of visual stimuli (dotted line) that either comply (Panel A) or not (Panel B) with biological rules for a geometric circle (solid line). The velocity of the dot in the biologically consistent motion condition is constant and equals 22.24 cm.s-1 and varies between 13.81 cm.s-1 and 31.62 cm.s-1 for the biologically inconsistent condition. Right: Audiovisual stimuli consisting of combinations of visual and auditory motion characterized by their relative phases Φ (indexed V and A for vision and audition respectively).

The subjects had to synchronize their hand movement with the moving dot on a graphic tablet without seeing their drawing hand.

Mean of the motor reproduction in the four audiovisual conditions.
Fig 4.
Mean relative phase and 95% confidence intervals of the reproduced motion as a function of visual and auditory kinematics, illustrating the distinct influences of both factors (i.e., no interaction).
