چکیده:
The present study attempted to investigate the emergence of especial skill in shooting with air gun at two skill levels
(skilled, novice). The population studied here included all male and female shooters from the city of Semnan. The
study was conducted on a sample of 40 shooters, consisting of two groups of women with the mean age of
21.33±2.26 and two groups of men with the mean age of 23.44±23.44, who displayed their shooting abilities with air
guns from five points (8, 9, 10, 11, 12 meters) from the target. The test was conducted in 4 sets (with 15-minute rest
intervals) each consisting of 5 blocks of 25 with 20 shots at each point (100 shots in all). The gap between each set
was the resting time of 15 minutes. A significant difference was found between the actual and predictive scores in all
groups (p<0.05): the differences found between actual and predictive scores were significant at P=0.012 for skilled
male shooters, P=0.023 for novice male shooters, P=0.001 for skilled female shooters, and P=0.021 for novice
female shooters. These findings of this study support the emergence of especial skill in all groups of air gun shooters.

To test the visual-context hypothesis as a factor involved in the emergence of especial skills, Keetch, Lee, and Schmidt (2008) asked skilled basketball players to perform free-throw shots at the free-throw line or some other points located at a similar distance from the basket but at different angles.
Our findings confirmed the presence of especial skills in air gun aiming among the members of the four groups of participants (skilled male, skilled female, novice male, and novice female shooters), as mean scores in actual performance of the skilled male and female shooters were significantly different from the predictive regression scores, consistent with the findings of Keetch et al.
Our findings for two groups of skilled shooters (significant difference between mean actual and predictive scores) at 10 m from the target (actual distance in air gun shooting) can be compared to the findings of Keetch et al.

Evidence from the present study on the emergence of especial skills in air gun aiming confirms the impact of specificity in motor control, and only one theory has described in details the process of specificity in motor learning."
