please select the best answer from the choices provided
○ a
○ b
○ c
○ d

Explanation:

Strayer and Johnston's (2001) study focused on driving and cell - phone use. They found that cognitive distraction (not just manual, as in hands - free vs. handheld) from talking on any cell phone (including hands - free) impairs driving performance. This impairment leads to an increased chance of missing traffic signals.

• Option A is incorrect because even hands - free phones cause cognitive distraction.
• Option B: The study was about cell - phone use, not talking with friends in the car.
• Option C: The study was centered on cell - phone use, not radio listening.

Answer:

D. Driving and talking on any type of cell phone increases the chance of missing traffic signals.
