| Abstract;Purpose: The saccadic reaction time (SRT) was measured as a saccadic movement parameter using visually guided tasks. Subjects and Method: The SRT was measured for nine healthy adult subjects aged from 28 to 49 years. The visually guided tasks for saccadic movement induction were simultaneous, gap, overlap, delayed-memory, and anti-SM tasks. Results: The median of the SRT (msec) for each task in thy actual measurements was as follows: 216 for the simultaneous task, 180 for the gap task, 240 for the overlap task, 234 for the delayed-memory task, and 292 for the anti-SM task. The SRT distribution of each subject exhibited two peaks for the gap task but moslly one peak for each of the other tasks. The first peak, observed in the SRT distribution for the gap task was an eysress saccade. Conclusion: The SRT for the gap task was the shortest and the SRT got longer in the order of the simultaneous task, and the overlap task, and the anti-SM task. Some subjects easily showed an express saccade in the gap task, but others did not. (author abst.) |
