(a) Various news reports have verified that Israeli soldiers have killed thousands of Palestinian civilians (including women and children) over the past few years in their attempts to control terrorist activity in the West Bank. Using the principle of classical conditioning, explain why a Palestinian who has witnessed some of these killings would develop a negative reaction to Israeli soldiers. Identify the unconditioned stimulus, unconditioned response, neutral stimulus, conditioned stimulus, and conditioned response in this example.

(b) Provide a plausible example of each of the following in the classical conditioning described above: stimulus generalization, extinction, spontaneous recovery.
