VISUAL REGULATION OF GAIT IN BIPEDAL LOCOMOTION - REVISITING LEE, LISHMAN, AND THOMSON (1982)

This study expanded the database regarding the visual regulation of ga it in the long jump approach (LJA) in the direction of novice long jum pers. It showed that the pattern of visual influence on gait adjustmen ts was similar for novices and experts. This was taken to indicate tha t visual regulation of gait in the LJA is not a specially trained skil l as much as it is a natural means of controlling gait. The study also showed that novices' step lengths were regulated principally by modif ying vertical impulse. This finding replicated that of an influential study by D. N. Lee, J. R. Lishman, and J. A. Thomson (1982). Results a re discussed with respect to the prevailing ecological notion that the optical variable tau provides principal informational support for reg ulation of gait in the LJA.
