Abstract
The aim of this study was to investigate the effect of observational practice on anticipation and visual search behavior in handball players in handball defense positions. The participants were 23 male handball players aged 16-19 years, who were members of Isfahan national youth and Pishgaman team. The players viewed clips of handball defense positions using eye-tracking glasses. They verbally expressed their anticipation about the outcome of the ball position during the pre-test. The players were divided into two groups: gaze behavior, which was observed (observation of output clips of eye-tracking glasses) and observation group, which observed only handball clips. Then the two groups were retested after 10 sessions of 45 minutes. The results of repeated measures analysis of variance and Muchly test with sphiricity assumed illustrated that the anticipation accuracy and visual search behavior of the gaze behavior group in the post-test were significantly better than the observation group. Defending handball players in the 3×3 position compared to the other two positions (2 × 2, 1 × 1), focused on the background and kinematics of the attacking player to anticipate and identify the attacking player pattern.

Abstract
Many studies have shown the effectiveness of verbal instructions and observational training on the improvement of children’s motor skills; however, there is not enough information about the simultaneous effects of these two variables. The aim of this study was to investigate the effect of attention instructions during observation of the model on gaze behavior and accuracy of overarm throwing in children. 24 children 7 to 10 years of age with normal growth selected purposefully and randomly divided into two internal and external attentions during modeling groups. Training in both groups included observation 10 times skilled model overarm throwing’s film with eye movement recording, with the difference that before it each group received its own instruction. The results of mix-ANOVA and paired and independent t-tests showed that both groups showed a significant increase from the pre-test to post-test in the accuracy (p=0.001; p=0.001) and duration of the quiet eye (p=0.005; p=0.001) of overarm throwing. In the post-test, the external attention during modeling group compared to the internal attention during modeling had significantly higher accuracy (p=0.01) and longer quiet eye duration (p=0.001). Also, the external attention during modeling had more percentage viewing time to relevant external cues (ball and trajectory). Therefore, directing visual attention to movement effect of observed pattern cause improvement in motor performance and visual-motor expertise in children.
