In a first experiment it was shown that the mean amplitudes of initial saccades from primary position to auditory targets were significantly affected by the simultaneous occurrence of a distracting visual stimulus.

In a second experiment, a similar procedure was carried out, but the eyes started by looking at a point at 15 degrees eccentricity.
