Explain how a specific phobia could be acquired through classical conditioning,being sure to identify the unconditioned stimulus,unconditioned response,conditioned stimulus,and conditioned response in your example.Also,using classical conditioning,indicate how the phobia could be eliminated.

 Good responses to this question should clearly identify a stimulus that is neutral and that occurs before a significant biological event that produces strong fear.The response should also indicate that the stimulus becomes conditioned,and there is now a conditioned response (a phobia)to the event that was originally neutral.Very good responses might indicate that the fear would generalize to other stimuli that shared similar characteristics with the original stimulus,and that the fear response may be maintained by negative reinforcement (avoidance or escape).All responses should also indicate that the phobia may be eliminated through extinction (exposure to the CS without the expected UCS).
