The phenomenon of protection from extinction (PFE) of a conditioned stimulus (CS) by a conditioned inhibitor (CI) has not been yet unequivocally demonstrated for the CS-CI compound in which the CS precedes the onset of the CI. Preliminary data from a project addressed to this problem strongly indicate that PFE is a real and robust phenomenon. Moreover, the protection is demonstrated not only for the CS duration overlapping with the CI but also for the early part of the CS which is not prevented by the CI from eliciting a conditioned response. The review of a few theories of conditioning suggests that the phenomenon of PFE is theoretically acceptable and predicted within the framework of any hypothetical mechanism which allows for post-trial "processing" or "consolidation" of information acquired during the trial.
对于条件刺激（CS）先于条件抑制（CI）出现的CS-CI复合刺激，条件抑制（CI）对条件刺激（CS）的防止消退（PFE）现象尚未得到明确证实。针对这一问题的一个项目的初步数据有力地表明，PFE是一种真实且强大的现象。此外，不仅在CS持续时间与CI重叠时能证明这种保护作用，在CS的早期部分（CI并未阻止其引发条件反应）也能证明这种保护作用。对一些条件作用理论的综述表明，PFE现象在理论上是可以接受的，并且在任何允许对试验期间获得的信息进行试验后“处理”或“巩固”的假设机制框架内都能得到预测。
