本研究的主要目的在探討不同位置的籃球選手，在進攻模式不同的視覺前線索時段下，預期能力上的差異。以12位高中女生籃球校隊選手為受試對象，將其分為中鋒組、前鋒組以及後衛組。各組選手面對數位攝影機拍攝進攻模式畫面，將拍攝所得的畫面剪輯成階段一：從預備接球姿勢到受試者雙手接觸到球時；階段二：從預備接球姿勢到受試者出手時；階段三：從預備接球姿勢到受試者出手後40毫秒；階段四：從預備接球姿勢到受試者出手後100毫秒，將所得影月經剪輯復編輯成测驗題目，讓所有受試者對所有的畫面進行判斷。二因子混合設計變異數分析結果發現：在進攻模式出手前之不同時段有顯著差異，顯示各組在時段四的預期能力優於時段一、時段二以及時段三，但在進攻不同位置之預期能力沒有顯著差異，並且在進攻模式出手前的四個不同階段動作與不同位置的籃球選手之間沒有交互作用存在。

The purpose of this study was to identify the difference of anticipation between the basketball players with different defensive positions. Participants were 12 female high school basketball players (4 guards, 4 forwards, and 4 centers). Each group of participants recorded the whole attacking process as four phases. Phase one was starting from pose to capture ball till the hall was touched by her hands. Phase two was starting from pose to capture till her hands has been out. Phase three was starting from end of phase two till 40 mini-seconds after it. Phase four was starting from beginning of first phase till the 100 mini-seconds after phase two. The results were found that: It has significant difference of the offense pattern in the different stage and the different positions before shooting, furthermore, the offense pattern before the fourth stages of shot to score points was obviously higher than the first, second, third stage to score points. The testes of the different position in the offense pattern before the four stages of shot anticipated ability to score points have no significant difference.
