The repeated tone is the CS (conditioned stimulus) and the puff of air is the US (unconditioned stimulus). Initially, the puff of air will elicit the eyeblink reflex without any prior learning - this is the UR (unconditioned response). After repeated pairing with the tone, the tone alone will eventually elicit the eyeblink reflex - this is the CR (conditioned response). Therefore, blinking to the tone presented without an air puff is the CR.
