As Cecelia talked to her daughter on her cell phone, she failed to slow when cars in the same lane were stopping and hit the car in front of her. Why didn't she stop?
 
  Reaction time slows considerably starting around age 50.
  If she were using a hands-free device, she would have stopped.
  The ability to multitask becomes more difficult over the years.
  Cell phone use seems to make the brain ignore what the eyes see.

Question 2

When developmentalists use the term expert, they usually mean a person who
 
  is extraordinarily gifted in one area.
  has earned advanced credentials in his or her special area.
  is innately skilled.
  is significantly better than others at performing a certain task.
