根据时间的标量性质的假设，变异性与时间的比率应该是恒定的。三个实验在有限的持续时间范围内（标准值= 1，1.3，1.6和1.9秒）测试了这一假设的有效性。在每一个实验中，时间间隔被区分，再现，或分类提出了2，4，或6个简短的连续听觉信号标记1，3，或5个间隔，分别。在实验1中，参与者被要求指出第二系列声音的间隔是否比第一系列声音的间隔更短或更长。在实验2中，必须重现标准间隔。在实验3中，在10次标准介绍后，参与者必须将每个比较间隔归类为比标准更短或更长。除了显示当仅提供1个间期时性能通常较差并且无论提供3个还是5个间期均保持大致相同（实验I和3）之外，结果还表明变异性与时间比在标准间期条件下并不恒定。总体而言，1.9时的比率高于1 s时的比率。无论使用什么方法，都会发生这种标量计时冲突，并且不会与间隔数变量交互。
According to the hypothesis of a scalar property for time, the variability to time ratio should be constant. Three experiments tested the validity of this hypothesis in a restricted range of durations (standard values = 1, 1.3, 1.6, and 1.9 s). In each experiment, time intervals to be discriminated, reproduced, or categorized were presented with 2, 4, or 6 brief successive auditory signals marking 1, 3, or 5 intervals, respectively. In Experiment 1, participants were asked to indicate whether the interval(s) within a second series of sounds were shorter or longer than those of the first. In Experiment 2, the standard interval had to be reproduced. In Experiment 3, after 10 presentations of the standard, participants had to categorize each comparison interval as shorter or longer than the standard. In addition to showing that performance was generally poorer when only 1 interval was presented and remained about the same regardless of whether 3 or 5 intervals were presented (Experiments I and 3), the results demonstrated that the variability to time ratio is not constant across the standard interval conditions. Overall, the ratio is higher at 1.9 than at 1 s. This violation of scalar timing occurs whatever the method used and does not interact with the number-of-interval variable.
