The purpose of this study was to investigate the influence of an assisting mark, The a cross (a vertical line and a horizon line), which was put on the target to stabilize aiming in archery. Subjects in this study were nine male and one female university archers. They were required to aim at the center of the target for 5 sec. as in archery competition. Dependent valuables were frequency, angle of eye movement and eye fixation time. This study assumed that the presense of a cross on the target makes it easier to aim than under normal conditions. Hypotheses were as follows : (1) Frequency of eye movement for the cross condition is less than that for normal condition in aiming. (2) Eye fixation time for the cross condition is longer than that for normal condition in aiming. (3) Angle of eye movement on cross line condition is smaller than that for normal condition in aiming. The results of analysis indicated that the three hypothesizes were supported and that subjects focused attention on the center of the target when the cross was present on the target.
