What does listening to others while driving do to cognitive capacity?

• A. Listening to others while driving reduces cognitive capacity by about 40%.
• B. Listening improves cognitive performance.
• C. Only texting affects cognition.
• D. Cognition is unaffected.

Answer: (A)

Dividing your attention while you drive lowers the mental resources you can devote to the driving task. Listening to others requires processing speech, understanding what’s being said, and deciding how to respond, which uses working memory and attention. Driving also needs you to monitor speed, distance, and potential hazards, so these tasks compete for the same cognitive capacity. That competition can reduce your ability to notice hazards and react quickly, often described as a notable drop—about 40% in some driver-training materials. So this choice reflects the idea that listening to others can significantly cut into cognitive resources. The other ideas aren’t supported: listening to others doesn’t boost performance, cognition isn’t unaffected, and it’s not accurate to say only texting affects cognition.
