Explanation:

Tongue clicking was neutral; it did not cause any reaction in Francis. However, tongue clicking became associated with tickling. Tickling does cause Francis to squirm and giggle. Later, even if tickling is not happening, just the tongue clicking is enough to trigger the conditioned response of squirming and giggling. Therefore, tongue clicking is the conditioned stimulus.
