三个实验考察了轨迹间隔的分布形式对轨迹条件化的影响。在实验1和2中，两组大鼠条件反射到一个固定持续时间的条件刺激（CS）在跟踪间隔程序;固定组中的大鼠收到一个固定持续时间的跟踪间隔，而在组变量的跟踪间隔的大鼠。在CS期间，Var组的应答率高于Fix组，而在跟踪间隔期间，反向Fix组的应答率差异高于Var组。实验3研究是否更大的反应率观察到在CS组变量是由于性能的影响或收购更大的关联强度的CS。跟踪条件反射后，从实验1的大鼠进行了第二阶段的延迟条件反射与相同的CS; 5-s的听觉刺激与15-s CS的最后5 s的化合物，和非条件刺激（US）的CS的偏移交付。在单独使用听觉刺激的测试中，Var组的受试者在听觉刺激期间的反应率低于Fix组。我们将这些发现解释为证据，即CS期间组Var中的上级响应是其获得比组Fix更大的关联强度的结果。
Three experiments examined the effect of distribution form of the trace interval on trace conditioning. In Experiments 1 and 2, two groups of rats were conditioned to a fixed-duration conditioned stimulus (CS) in a trace interval procedure; rats in Group Fix received a fixed-duration trace interval, whereas for rats in Group Var the trace interval was of variable duration. Responding during the CS was higher in Group Var than in Group Fix, whereas during the trace interval this difference in responding reversed—Group Fix showed higher response rates than Group Var. Experiment 3 examined whether the greater response rate observed during the CS in Group Var was due to a performance effect or the acquisition of greater associative strength by the CS. Following trace conditioning, the rats from Experiment 1 underwent a second phase of delay conditioning with the same CS; a 5-s auditory stimulus was presented in compound with the last 5 s of the 15-s CS, and the unconditioned stimulus (US) was delivered at the offset of the CSs. On test with the auditory stimulus alone, subjects in Group Var showed lower response rates during the auditory stimulus than subjects in Group Fix. We interpreted these findings as evidence that the superior responding in Group Var during the CS was a result of it acquiring greater associative strength than in Group Fix.
