本研究目的在探討狀態性焦慮（state anxiety）對反應時間（TRT）之中樞訊息處理（前動作時間，PMT）以及周邊肌肉執行速度（動作時間，MOT）的影響。受試者為大專和研究所學生，身體健康之志願者男性22位女性8位。受試者隨機分派至實驗組（給予高塔跳傘之焦慮情境）或控制組（不給予焦慮情境）各15位。經收集其狀態性焦慮分數、心跳率、反應時間（包括前動作時間PMT與動作時間MOT）之資料，以獨立樣本t考驗進行分析。結果顯示高狀態性焦慮可延緩反應時間以及前動作時間，但對動作時間則無顯著影響。由於反應間乃由中樞訊息處理之動作時間及周邊肌肉執行之動作時間組成。是故狀狀態性焦慮之造成反應時間之延緩主要在於中樞訊息處理速度減緩所致。

The purpose of this research was to examine the effect of state anxiety on the central information processing speed (the promotoe time, PMT) as well as peripheral executing speed (the motor time, MOT) in the total reaction time (TRT). The subjects were 22 male and 8 female university and graduate volunteers who were in good health condition. The subjects were randomly assigned to the experiment group (receiving the frightening situation of jumping from a tower with a parachute) or the control group(not receiving any frightening situation). Each group consisted of 15 people. The dependent variables included state anxiety scores, heart beat rates, premotor time, motor time and total reaction time. These variables were analyzed using the independent t-test. The results indicate that high state anxiety may reduce the total reaction time and premotor time, but not the motor time. In other words, high state anxiety may slow down the central information processing speed, but may not affect the peripheral executing speed. The slow down of the total reaction time is mainly due to the reduction of the central information processing speed.
