From the UK Guardian Unlimited:

"...'We are getting together a group of 20 children with imaginary friends and 20 without. Then for the study we will ask them to do tasks to try and establish whether there are differences in language skills and other areas,' she said.

'Children with these kinds of companions have strong imaginations and are often very creative, which can be really useful to them as they develop.'..."

Indrid has only one question; when are they going to address the issues relevant to children with imaginary enemies?
