The Effect of Event Occlusion of Different Parts of Body on Visual Search and the Prediction of Futsal Penalty Skill

Background: This article aims at investigating the effect of event occlusion of different parts of human body on reconstruction and prediction of futsal penalty skill among futsal players and non-futsal players. Materials and Methods: In so doing, the study utilized two independent groups, oneincluding 12 subjects of futsal players and the other including 12 subjects of not futsal players at Allameh Tabataba’i University. Appropriate occlusions were made using Microsoft software of Total Video Converter and Paint in Windows Operating System on 20 selected scenes of futsal. In this experiment, the selected scenes were presented to the subjects in both groups through Ulead Media Studio software and the subjects wereasked to reconstruct the scenes and predict the hitting place using the available visual information. Their comments and predictions were recorded and the subjects were scoredregarding the distance to the main target (true place of target). Finally, the overall score of each subject in 20 attempts was calculated and recorded. Kolmogorov–Smirnov Test, levene's Test, and Variance Analysis test with repeated measures were used to analyzethe data. Regarding the significant scale of 0/05, the answer to all the questions posed earlier in this article was positive. Results and Discussions: It was identified that there is a significant difference in theeffect of event occlusion of different parts of body on visual search and the prediction of futsal penalty skill. A significant difference was also found between the group of futsal players and the group of non-futsal players in different occlusions.Conclusion: The results showed that futsal players and non-futsal players in fact use the information of different parts of body in visual search. The omission of visualinformation resulted from legs among futsal players and the omission of the information resulted from arms-head among non-futsal players caused the most significant damage to visual search and the prediction of subjects.
