Previous studies have shown that the human cerebral hemispheres are functionally asymmetrical. In addition, differential hemispheric activation has been brought about by shifts in lateral visual orientation. In view of this information, an experiment was conducted to study the effects of the lateral placement of displays with spatial-type information on human performance. Thirty two right-handed males were required to respond to peripherally-located engine monitoring displays while performing a centrally-located compensatory tracking task. For half of the subjects the engine monitoring displays were presented to the left of the tracking display and for the other half the engine monitoring displays were presented to the right of the tracking display. Performance was found to be better for those subjects who were required to orient to the left than for those who were required to orient to the right. The results of this experiment support the theory that cerebral activation may be an important consideration when locating certain types of visual displays in a high workload cockpit environment.
