My son is remodeling his basement and installed a vapor barrier (plastic) behind the the wall studs. He insulated between the studs with paper face insulation. It appears that between the insulation and and barrier there is moisture. He has had a piece of drywall up and there is no moisture behind that area. Is the drywall acting as an insulating feature. It has been very cold Here. Would a polystyrene board between the barrier and insulation help or will the drywall suffice. I told him to start pulling the insulation to let everything dry out.

Without knowing the dynamics of the foundation, it is difficult to make any suggestions. Any method that will not trap moisture is better than one that does. No matter what, mold resistant drywall should be used in a basement application.
My company does a lot of work in basements. Since most basements were not designed to be living areas, we suggest allowing for airflow behind any built wall. You will lose some insulation value, but will not have to worry about trapping air/condensation.
