Question: 87

12. Researchers discover that polymorphisms in the DRD2 gene can be associated with thrill-seeking behavior, and that individuals with certain forms of the gene are more likely to become extreme athletes and have more dangerous hobbies. Which of the following theories is supported by this discovery?

I. The social cognitive perspective

II. The behavioral perspective

III. The biological perspective

  • A. I only
  • B. III only
  • C. I and III only
  • D. II and III only

Correct Answer: C

Explanation:

This research supports a link between genetic expression and behavior, which is a central tenet of the biological perspective. The social cognitive perspective also holds that people's behaviors and traits shape their environments, which in turn have an effect on their identity, so the discovery also supports this perspective. Behaviorism is not supported, as the discovery is not related to rewards and punishments.
