Jet fighter pilots are representative of an elite visual population with regards to performance on tests of dynamic visual acuity, visual reaction and total response times and contrast sensitivity. To date no studies have been conducted which test jet fighter pilot's performance on tests of stereomobilization. Thirty two jet fighter pilots were tested for stereomobilization ability with gross and fine disparities of 450 and 75 arc seconds using a computer program for the Macintosh color computer. The results were compared to previously established non pilot data. There was a significant difference between the pilot's and non pilot's performance for the gross disparity, with the non pilots scoring at a higher level. When comparing the pilot's to non pilot's performance for the fine disparity, however, there was no significant difference. There was a significant difference between the non pilot's performance for the gross and fine disparities, with the fine showing a lower level of performance. The pilots, however, showed no significant difference in performance between the gross and fine disparities, suggesting a possible learning effect. Physiological stereomobilization threshold was not achieved for either 450 or 75 arc second disparities using a stereo target presentation duration of 15msec.
