本研究主要目的在採討不同性別與運動類型之受試者在「視覺範圍注意資源分配能力」之差異。本研究的受試者男、女各40名，共計80名，並區分為排舉球員（20名）、
攻擊手（20名）與非運動員（40名）。所有受試者在經過二階段的分段練習後，於第三階段進行「球體捕接與刺激偵察平行測驗」。

實驗所得資料，採事前比較以獨立樣本二因子變異數分析進行統計分析，比較結果與討論之後，獲得下列結論：排球動員在視覺範圍注意資源分配的能力上顯著優於非運動員；而排球舉球員與攻擊手以及男、女排球運動員在此一能力上則沒有顯著不同。

另外男、女排球運動員與非運動員及男、女排球舉球員與攻擊手在視覺範圍注意資源分配的能力上也沒有交互作用存在。由此，研究者推論個體注意資源分配能力的發展
主要受外在環境因素的影響，由於排球運動情境中處處潛藏著注意資源分配能力的訓練，在這種潛移默化的情境下，運動員注意資源分配能力很自然就能夠獲得發展。因此，教練們在選手體能與技術精進的基礎之下，有必要針對排球運動情境的特殊性，擬訂一套增進選手注意資源分配能力之訓練計畫，如此將有助於運動員突破高原、邁向高峰。

The study aims to deterimine the varying "
degrees of visual range and attention" of participants having different sexes and different field roles in the game. The test group is composed of 80 participants, 40 of which are male and 40 are female. The group is classified into ball tossers in volleyball (20) , strikers (20) and non-athletes (40).
All participants of the group have undergone two phases of training prior to the experiment. During the third training phase a " ball receiving ability and stimulus parallel test " was conducted. The data from the pre-experiment two-way variance analysis on the difference of two sample variables revealed that : Volleyball players show a better degree of visual range and attention compared to that of non-atletes; whereas, volleyball players of both sexes and field role classifications show the same degree of ability. Moreover, no instances of interaction has been observed in the visual range and attention between the volleyball players, male & female alike, and non-athletes and between the ball tossers and strikers ,male & female alike.Therefore, the study conclides that environ-mental factors are the major influences affecting the development of the individual's visual range and attention.
Hence, the study proposes that coaches should also pay attention to the playing style used by a particular volleyball player , at the same time that they are observing the stamina and skills exhibited by the player during screening time.Furthermore, coaches should also prepare a training program for the improvement of the degree of their players' visual range and attention ; such training will prove to be an asset in helping players achieve and record-breaking performance.
