49. As a child, Nelson accidentally disturbed a wasp's nest and was stung by several wasps. He now has a phobia of flying insects. Which of the following best explains the acquisition of Nelson's phobia?
Answer: B
Nelson's phobia of flying insects is best explained by classical conditioning.
Nelson's phobia stems from a past traumatic experience where he was stung by wasps, which has created a conditioned response to flying insects. This aligns with the principles of classical conditioning, where an emotional response to a neutral stimulus (flying insects) develops due to an association with an unconditioned stimulus (the pain from the wasp stings).
A) Operant conditioning
Operant conditioning involves learning through consequences, where behaviors are strengthened or weakened based on rewards or punishments. In this case, Nelson's phobia is not a result of such reinforcement or punishment but rather a learned fear from a negative experience, making this option incorrect.
B) Classical conditioning
Classical conditioning explains how a neutral stimulus, such as flying insects, becomes associated with a fearful response due to a traumatic experience (the wasp stings). Nelson's phobia is a direct result of this conditioning process, making this the correct choice.
C) Observational learning
Observational learning occurs when individuals learn behaviors by watching others. While it is possible for phobias to be acquired through observing someone else’s fear, Nelson's phobia specifically arose from his own direct experience with wasps, so this option does not apply.
D) Rote learning
Rote learning refers to memorization through repetition without understanding the underlying concepts. This type of learning does not account for the emotional and psychological aspects of phobia acquisition, which are based on experiences rather than mere memorization. Therefore, this option is not relevant to Nelson's situation.
Conclusion
Classical conditioning is clearly the most fitting explanation for the development of Nelson's phobia, as it encompasses the direct association between his painful experience with wasps and his subsequent fear of flying insects. The other options fail to account for the emotional response that arises from direct, traumatic experiences, making them unsuitable explanations for his phobia.
