Reconditioning and spontaneous recovery are both phenomena that demonstrate that an extinguished CR is not forgotten. Reconditioning occurs when a new CS is paired with the originally extinguished CS, which results in a faster relearning of the CR than during the initial acquisition phase. Spontaneous recovery occurs when the previously extinguished CR reappears after a period of time has passed without any further training.
