In 3 experiments, rats were used to investigate the conditions that influence the transfer of a conditioned emotional response from 1 context to another. The subjects experienced training in 2 contexts on each day. In Experiment 1, subjects received a single conditioning trial with a different target stimulus in each of the 2 contexts. Conditioned responding was found to be more vigorous when the target was presented subsequently in the context in which conditioning had taken place than when it was presented in the other context. Experiments 2 and 3 confirmed these results and also showed that neither the unconditioned response evoked by the target stimulus nor the conditioned response acquired after multiple training trials showed evidence of context specificity. Possible reasons for the difference in outcome between single-trial and multitrial conditioning procedures are discussed.
在3项实验中，使用大鼠来研究影响条件性情绪反应从一个情境转移到另一个情境的条件。实验对象每天在2个情境中接受训练。在实验1中，实验对象在2个情境中的每个情境中接受一次针对不同目标刺激的条件化试验。结果发现，当目标随后在进行条件化的情境中呈现时，条件反应比在另一个情境中呈现时更强烈。实验2和实验3证实了这些结果，并且还表明目标刺激引发的无条件反应以及多次训练试验后获得的条件反应均未显示出情境特异性的证据。讨论了单次试验和多次试验条件化程序结果差异的可能原因。
