Answer:
After being shocked for the last ten days when kissing your wife, you now feel mildly anxious whenever you approach her to give her a kiss. In classical conditioning, your wife was a(n) neutral stimulus ten days ago and has now become a(n) conditioned stimulus.
Step-by-step explanation:
According to the classical conditioning, the human's behavior is based on stimulus, for the good or for the bad. When a stimulus is neutral, it means that for your body and mind, this stimulus didn't have any response or result, and you feel completely normal. On the other hand, when you suffer a trauma or something that reminds you of a bad thing, then there is a condition for your brain. That's the case of this man. His wife kiss reminds you something bad that had occurred, and then you begin to refuse to kiss her.
