Corriveau's team said their results showed that once children learn to read, "they rapidly come to regard the written word as a particularly authoritative source of information about how to act in the world." They added that in some ways this result is difficult to explain. Young readers are exposed to a good deal of fantasy and fiction in written form, so why should they be so trusting of written instruction? Perhaps they are used to seeing adults act on the basis of written information - such as maps, menus, and recipes - but then again, pre-readers will also have had such experiences. This suggests there's something special about the process of learning to read that leads children to perceive written instruction as authoritative.
