The psychology of color that a child would most likely choose

As a UI designer, I have always wondered if there has been any psychological studies that can prove that children will pick certain colors over other colors or if there is a common pattern that occurs when having to make a decision based on color without the children having been overly subjected to too many decisions and influences in life.

What are your thoughts or do you know any steps in the right direction for gathering some useful information on this topic.
