摘要：Purpose: The purpose of this study is to examine the specific memory representation in special skill of Basketball Free
Throw in distances (a “set shot”) except 4.5 m distance. It is aimed to examine the role of the Index of Difficulty
(ID) in creating the specific memory in other distances except the distance of penalty shoots.
Material: Fifteen skilled basketball players (M age = 21.6 years, SD = 2.45 years) were chosen from sixty players; they
performed 70 trials from 7 different distances on the first day (10 SHOTS from each distance toward the
basket). The next day, each player performed 10 SHOTS from each distance, but this time, it was different in
terms of the baskets’ sizes and their quantities.
Results: The result of linear regression on trials score on the first day revealed the representation of special skill in
penalty point and on the second day, representation of special skill was seen in 3 different distances from
the ring (manipulated ring). These results indicate that Index of Difficulty protection can be a factor of private
memory representation in distances except 4.5 m distance.
Conclusions: Results suggest that mass training stabilizes the ratio of target distance and width (Index of Difficulty) in mind
and this ratio is the main reason of specific memory representation in basketball free throw.
