Interhemispheric difference in visual evoked potential amplitude were measured in 32 right handed sonar operators. Each operators was also rated by his supervisor as to his performance using visual sonar displays. Significant interhemispheric asymmetries were found in the group as a whole and in the better performers. Poorer performers did not show asymmetries. These results suggest that the magnitude and direction of interhemispheric asymmetries in evoked potential amplitude can be used in the prediction of performance as sonar operators. These measures could be used to test the effect of training and watch standing schedules.
