36. 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.
Classical conditioning explains how an emotional response, such as fear, can be learned through association. In Nelson's case, the painful experience of being stung by wasps became associated with the presence of flying insects, leading to his phobia.
A) Operant conditioning
Operant conditioning involves learning through the consequences of behavior, such as rewards or punishments. In this scenario, Nelson's fear of flying insects does not arise from any reinforcement or punishment related to his behavior, but rather from a traumatic experience, making this option incorrect.
B) Classical conditioning
Classical conditioning is the process by which an individual learns to associate a neutral stimulus with an unconditioned stimulus that elicits an emotional response. Nelson's experience of being stung by wasps (unconditioned stimulus) caused him to develop a fear (conditioned response) of flying insects (conditioned stimulus), making this option the correct explanation for his phobia.
C) Observational learning
Observational learning occurs when an individual learns behaviors by watching others. In the case of Nelson, there is no evidence that he learned to fear flying insects by observing someone else; rather, his fear stemmed from a personal, traumatic experience, thus making this option incorrect.
D) Rote learning
Rote learning refers to memorization through repetition without understanding. This concept does not apply to the development of phobias, as it does not involve emotional responses or conditioning, making this option irrelevant to the question.
Conclusion
Classical conditioning effectively explains how Nelson developed his phobia of flying insects through a direct association between the painful experience of being stung and the sight of the insects. The other options—operant conditioning, observational learning, and rote learning—fail to account for the mechanism by which Nelson's fear was acquired, as they do not involve the emotional associations that underlie phobias.
