大鼠判断时间间隔的选择程序，其中准确性保持在约75%的正确。对于2.0-32.0 s的短持续时间，间隔之间的间隔为1.0-或2.0-s，对时间的敏感性（d '）近似恒定（每组n = 5，实验1），2.0-50.0 s，间隔2.0 s（n = 2，实验1），和0.1-2.0 s，0.1-或0.2-s间隔（每组n = 6，实验2）。然而，观察到系统偏离平均灵敏度，灵敏度的局部最大值约为0.3、1.2、10.0、24.0和36.0 s。这种系统偏离近似常数d'的现象是由具有多个振荡器的联结主义时间理论预测的，并且可能需要修改标量定时理论的线性定时假设。
Rats judged time intervals in a choice procedure in which accuracy was maintained at approximately 75% correct. Sensitivity to time (d') was approximately constant for short durations 2.0-32.0 s with 1.0- or 2.0-s spacing between intervals (n = 5 in each group, Experiment 1), 2.0-50.0 s with 2.0-s spacing (n = 2, Experiment 1), and 0.1-2.0 s with 0.1- or 0.2-s spacing (n = 6 in each group, Experiment 2). However, systematic departures from average sensitivity were observed, with local maxima in sensitivity at approximately 0.3, 1.2, 10.0, 24.0, and 36.0 s. Such systematic departures from an approximately constant d' are predicted by a connectionist theory of time with multiple oscillators and may require a modification of the Linear timing hypothesis of scalar timing theory.
