Two experiments with rats investigated the temporal relationships under which conditioned inhibition will transfer to an independently conditioned excitor (CS) in a summation test. Experiment 1 trained 2 simultaneous inhibitors with either a trace or delay excitatory CS. Transfer of inhibitory behavioral control depended on the temporal relationship of the transfer CS to the unconditioned stimulus (US). Experiment 2 extended these findings by training 2 inhibitors (1 simultaneous and 1 serial) with a single delay excitatory CS. Again, testing with trace and delay transfer CSs found that transfer of inhibitor control depended on the temporal relationship of the transfer CS to the US. In both studies, maximal inhibition was observed when the inhibitor signaled US omission at the same time as the transfer excitor signaled US presentation. The results are discussed in terms of the temporal coding hypothesis.
两项以大鼠为对象的实验研究了在总和测试中条件性抑制向独立条件性兴奋刺激（CS）转移时的时间关系。实验1用痕迹或延迟性兴奋CS训练了2种同时性抑制物。抑制性行为控制的转移取决于转移CS与无条件刺激（US）的时间关系。实验2通过用单一延迟性兴奋CS训练2种抑制物（1种同时性和1种序列性）扩展了这些发现。同样，用痕迹和延迟性转移CS进行测试发现，抑制物控制的转移取决于转移CS与US的时间关系。在两项研究中，当抑制物发出US缺失信号的同时转移兴奋物发出US呈现信号时，观察到了最大抑制。根据时间编码假说对结果进行了讨论。
