The process of extinction weakens the CR, but it does not eradicate the association between the CS and the US (unconditioned stimulus). When the CS is presented again after a rest interval, the animal may show spontaneous recovery, which means the reappearance of the CR even though the animal did not receive any reinforcement during the rest interval. The strength and persistence of spontaneous recovery depend on various factors, such as the length of the rest interval and the number of extinction trials. However, in general, the CS will usually elicit the CR again to some degree.
