Which statement best describes the impact of improved processing speed on adolescent problem-solving?

• A. Decreased efficiency in problem-solving.
• B. No change in overall cognitive functioning.
• C. Faster mental operations allow solving problems more quickly.
• D. More error-prone reasoning.

Answer: (C)

Improved processing speed means cognitive operations happen more quickly, so with the same amount of time you can complete more steps and retrieve needed information faster. In adolescence, faster mental operations let problem-solving steps be carried out more rapidly, which makes solutions come together sooner and can free up time for planning and verifying approaches. The result is a smoother, quicker problem-solving process. The other statements don’t fit because faster speed doesn’t reduce efficiency or leave cognitive functioning unchanged, and while speed can influence error patterns in some tasks, the main effect described here is achieving solutions more quickly, not more errors.
