内部时钟的性质，时间记忆和决策过程用于时间短的持续时间进行了研究。采用峰值间隔法评估8、12和21秒间隔的时间，并对平均响应函数和个别试验进行分析。一项干扰任务阻碍了计数，并且在每次试验后提供关于准确性和精确度的视觉反馈。平均响应分布(a)以适当的实时标准为中心，(b)高度对称，(c)变异性为标量。个别试验的分析表明，相对于反应阈变异性，记忆变异性更多。综上所述，这些结果表明，人类表现出与其他动物相同的定性定时特性，但在数量上存在一些差异。
The properties of the internal clock, temporal memory, and decision processes used to time short durations were investigated. The peak-interval procedure was used to evaluate the timing of 8-, 12-, and 21-s intervals, and analyses were conducted on the mean response functions and on individual trials. A distracter task prevented counting, and visual feedback on accuracy and precision was provided after each trial. Mean response distributions were (a) centered at the appropriate real-time criteria, (b) highly symmetrical, and (c) scalar in their variability. Analysis of individual trials indicated more memory variability relative to response threshold variability. Taken together, these results demonstrate that humans show the same qualitative timing properties that other animals do, but with some quantitative differences.
