I've been looking everywhere and can't seem to find the answer to this simple question.

Do you know of any research that addresses the question of "HOW MANY FACES THE TYPICAL PERSON CAN RECOGNIZE?" Not identify by name, but recognize. Bahrick's work examines the durability of face memories over time, but I'm more interested in an estimate of the sheer number. A cold beverage of your choice to the person that can help. Thanks.
