扫视反应时间 (SRT) 的分布通常偏离单峰正态分布，使用超质量程序检测 963 个数据集中的峰值，其中包含来自 170 名受试者的 90,927 个反应时间，大约 55% 显示 1 个、30% 2 个、12% 3 个和 3% 4 个峰值，根据它们沿反应时间尺度的聚类，模式可分为快速（90-120 毫秒）、快速常规（135-170 毫秒）和慢速规则（200-220 毫秒）模式，在单峰分布中，29% 在快速模式范围内有峰值，46% 在快速规则模式范围内有峰值，因此，87% 的数据集支持扫视反应时间分布是三种模式叠加的概念，所有实验分布均由过量质量测试确定的尽可能多的伽马分布拟合，显着性讨论了眼跳生成过程的多模态。 (C) 1997 爱思唯尔科学有限公司。
The distributions of saccadic reaction times (SRT) often deviate from unimodal normal distributions, An excess-mass procedure was used to detect peaks in 963 data sets containing 90,927 reaction times from 170 subjects, About 55% showed one, 30% two, 12% three and 3% four peaks, According to their clustering along the reaction time scale the modes could be classified into express (90-120 msec), fast regular (135-170 msec) and slow regular (200-220 msec) modes, Among the unimodal distributions 29% had peaks in the range of the express mode and 46% had peaks in the range of the fast regular mode, Therefore, 87% of the data sets support the notion of saccadic reaction time distributions being the superposition of three modes, All experimental distributions were fitted by as many gamma distributions as determined by the excess-mass test, The significance of the multimodality for saccade generation processes is discussed.
