The Doctor's Avatar will see you now...

Did you know why men frequently choose female avatars (graphic representations of themselves) in online virtual worlds? Dan Gottlieb had a guest with the answer yesterday on WHYY.

Dr. Dan Gottlieb is the Cherry Hill-based psychologist with the award-winning "Voices in the Family" show on local NPR affiliate WHYY-FM, had a great discussion Monday with researchers looking at the psychological impact of virtual worlds like Second Life.

His guests included Dr. Craig Kerley, who actually has a practice in Second Life. You can listen to the discussion as a podcast.
