采用1、2、4、7.5、15、25秒的准备时间，对25名精神分裂症患者和10名正常人进行反应时间实验。采用了两种方法。在常规的预警过程中，每个特定的区间连续出现多次。在不规则预警过程中，各种准备间隔以系统随机的方式呈现。主要发现是：1。正常人的反应时间明显短于患者，尽管有一定程度的重叠。两种方法中正常反应时间最短的时间间隔均为2秒。另一方面，患者的最短时间间隔稍长。2. 在正常被试中，常规程序的反应时间除25秒外显著短于不规则程序的反应时间，在25秒时两条曲线相交。这两个过程的区别…
Twenty-five schizophrenic patients and 10 normal subjects were used in an experiment on reaction time employing preparatory intervals of 1, 2, 4, 7.5, 15 and 25 seconds in length. Two procedures were used. In the regular warning procedure each particular interval was presented a number of times in succession. In the irregular warning procedure the various preparatory intervals were presented in a systematically random fashion. The principal findings were: 1. Normals showed significantly shorter reaction times than did the patients, although there was a small degree of overlap. The shortest reaction times of the normals occurred at the 2-second interval in both procedures. The patients on the other hand showed their minimum times with somewhat longer intervals. 2. In the normal subjects the reaction times of the regular procedure are significantly shorter than those of the irregular procedure at each interval except the 25-second, at which point the two curves crossed. The differences between the two proce...
