Purpose: Strengthening visual perception increases visual processing and sports performance. The purpose of this study is to investigate the different levels of difficulty of executive control tasks on endogenous, exogenous, and inhibitory attention.

Methods: The number of samples in this present was 42 girls (20-35 years old) beginners in table tennis, who were placed in four homogeneous groups (high difficulty/medium difficulty/low difficulty and control). In the pre-test phase, the participants first completed the attention networks test to check endogenous, exogenous, and inhibition attention and then performed special table tennis forehand skill exercises for eight sessions for 30 minutes. 24 hours after the last training session, the post-test was performed in the same way as the pre-test.

Results: There was a statistically significant difference between the moderate task difficulty group and the endogenous attention variable control group. There was no significant difference between the groups in the exogenous attention pre-and post-test. In addition, all groups had a significant improvement in the post-test of the inhibition variable.

Conclusion: This study showed the effectiveness of task difficulty in the moderate task difficulty group of endogenous attention and the effectiveness of task difficulty on task inhibition. Therefore, the research results can be used to design more effective exercises to increase visual perception.
