Finding out if communication is important is just much too vague - and it is generally agreed that it is.
How about a comparison of two people, Helen Keller and a feral child named Genie?

Their lives have been written about extensively, but as far as I know they have not been compared. You can draw some conclusions or theories about human communication in your last paragraphs.

You could call it 'The effects of lack of communication in two young lives.'
