Hand movement deviations in a visual search task with cross modal cuing

The purpose of this study is to demonstrate the cross-modal effects of an
 auditory organization on a visual search task and to investigate the influence
 of the level of detail in instructions describing or hinting at the associations
 between auditory stimuli and the possible locations of a visual target. In
 addition to measuring the participants reaction times, we paid special
 attention to tracking the hand movements toward the target. According to
 the results, the auditory stimuli unassociated with the target locations
 slightly but significantly- increased the deviation of the hand movement
 from the path leading to the target location. The increase in the deviation
 depended on the degree of association between auditory stimuli and target
 locations, albeit not on the level of detail in the instructions about the task
