Divided attention

I seem to be very bad at multi-tasking.
If am talking over the phone, I can do just that and not mix it with any other work.
If am listening to music, I just concentrate on the lyrics and the music and not do anything else.
But, there are people who are so good at carrying out multiple tasks at a time.
They drive, same time listen to music plus attend a phone call.
People listen to music while they read etc etc.,
Especially people belonging to this generation are very good at this.
I do not know,though, how much of the information that they gather during this inter-changing activities is really fruitful.

Many researchers quote that this type divided attention tasks though good in some respects, but may hamper the span of attention (the amount of time that is given to focus on a subject)of an individual.
The Internet has a big role to play in bringing down the span of attention of people, with people easily and quickly jumping from one web page to the other to find loads of information.

Of course, there are many people who are good at multi- tasking and have very good span of attention too.
Ultimately what matters is the quality of information that one is gathering.
