Q. Consider the task of driving in an unfamiliar area at night. Remember to answer the question with the human factors terminology.

a) Given what you know about human attention, why is this a more difficult task for the driver than driving in a familiar area at night?

Why would it be particularly more difficult for a driver to carry on a conversation, or consult someone over the phone for directions, in an unfamiliar vs. a familiar area?

b) Given what you know about human vision, explain two reasons why it is a more difficult task for the driver at night, than during the day.

Why, in terms of vision, might it be even more difficult for an older driver?

c) Engineers are implementing the design of a navigation system which provides verbal directions to drivers at the start of a journey. Given what you know about working memory storage and limitations, under what conditions would this system be successful? Under what conditions would drivers have trouble remembering the directions?
