One more book on children's drawings ?Not really. This is a kind of interactive book.Act 1: the authors provide scientific results from graphopraxic tests.Act 2: the children aged 4 to 7 then expose their free drawings in the gallery. Act 3: the reader compares them with relation to age and praxic ability, and eventually follows the child's individual production from theme to theme. It clearly appears that the skilled child from the praxic point of view does not regularly show artistic talents. Objets d'art are sometimes made by very young and praxically unskilled children. The reader becomes the judge. The book aims at defining precocious art and provides a new key to reading children's drawings.
