Way back in around 1964 I was one of a bunch of uni students who were used by the Road Research Board in
Denmark St, Kew Vic, as guinea pigs for a whole lot of research on different aspects of driver behavious and road safety. One of the areas looked at was the effects of radio and conversation in cars on driver reaction times. While we didn't have audio books to
test with, we were tested for reaction times when listening to music and having conversations etc. The results showed that such things tended to keep drivers awake and that they reacted faster when some sort of response was required. Interestingly, when given some sort of stimulus that requred a reaction, none of the subjects could ever remember what it was that they were listening to during their response (they could remember what they were listening to before, but not during, the response time.) The conclusion was that some sort of wireless background, or conversation, kept drivers sharper over long drives and that when required, they(we) were hit with a burst of adrenalin while dealing with the siuation and this simply blocked the other stimulus out until the situation was dealt with.
No one was tested on audio books, but comedy radio programs as
well as music were used and I'd imagine that responses to comedy radio would be pretty similar to audio books.
Other projects we were used on related to drive's ability to read various fonts on road signs; the effects of different colour combinations on road signs; whether or not drivers could judge speed after driving for long spells; intensity of light needed in traffic lights; analyzing data at traffic black spots that was later used as part of the case for compulsory
seat belts in Oz.
