| Summary: | 碩士 === 國立臺灣師範大學 === 體育研究所 === 85 === 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.
