What is the response to the conditioned stimulus that occurs after the pairing of a conditioned stimulus and an unconditioned stimulus?

You will get a conditioned response. Since i know that this topic can be complicated i'll try and make it a little easier to understand. An unconditioned stimulus is one that occurs naturally without any kind of training. As an example, look at the innate fears that we have due to evolution. Certain animals, bitter tastes elicit a response (such as running away or spitting out the bitter food). This is the unconditioned response. Another example is the eye blink response. When a puff of air hits your eye, you automatically blink. Now say for example when the puff of air hits your eye, a bell rings (a conditioned stimulus) and you blink. After this connection between the puff of air, the bell and eye blink has been learned, the bell ringing itself will cause you to blink in absence of the air puff. This is the conditioned response as naturally, hearing a bell ring, does not make you blink.
