The rants are given prominent placement in West's sets. He yells, screams and weaves rhymes into his conversation to make his points.

While fans at Kanye West's shows seemed to respond favorably to his pronouncements, the wild actions raised concerns in others�including those in the mental health field�who have questions about the rapper's mental wellbeing.

"He's a rapper and outspoken and giving some kind of emotional rant," said Dr. John Sharp, author of The Emotional Calendar: Understanding Seasonal Influences and Milestones to become Happier, More Fulfilled and in Control of Your Life. "It could be a reaction against money against corruption."

"He could be putting his feelings out there as if they are alive in someone else and not him," Dr. Sharp explained to Radio.com. "There is something called projective identification. It's when you are railing against something that you perfer to rail against rather than relate to. If you are angry you might see an angry guy and say that guy is really angry."

While Dr. Sharp is careful to point out that he cannot diagnose Kanye by watching a few tapes of what seems to be unusual behavior, he does say that people who use projective identification can learn to cope with their feelings in a more productive manner.
