Two dogs received a single paired classical conditioning trial, with tone CS and 12 mA shock US. Both dogs then showed a conditioned blood pressure increase in response to the nonreinforced CS, which extinguished with additional nonreinforced presentations. The CR showed spontaneous recovery four days later, but reextinguished with additional nonreinforced presentations. The results were interpreted as not supporting Eysenck's theory of "incubation" following one-trial aversive conditioning.
两只狗接受了一次配对经典条件反射试验，以音调作为条件刺激（CS），12毫安电击作为非条件刺激（US）。之后，两只狗在面对未强化的条件刺激时，都出现了条件性血压升高的情况，这种情况在额外的未强化呈现后逐渐消退。四天后，条件反应出现了自发恢复，但在额外的未强化呈现后又再次消退。这些结果被解释为不支持艾森克关于单次厌恶条件反射后“潜伏期”的理论。
