In a study, researchers paired a neutral tone with a puff of air to a participant's eye over repeated trials. Initially, the tone produced no eyeblink, while the air puff reliably elicited one. After many pairings, the tone alone began to produce a reliable eyeblink response. Researchers then presented the tone repeatedly without the air puff and observed gradual weakening of the eyeblink response.
If, after a 24-hour rest, the tone briefly elicits an eyeblink again without further training, this phenomenon is called

Explanation
Spontaneous recovery is the reappearance of an extinguished CR after a rest period, indicating extinction suppresses but does not erase the original learning.
