In her analysis of this detailed observation Cox noted how the child was ascribing meaning to the marks she was making and that 'reading' the drawing through the observed process gives some understanding of what the child's intentions were and how they changed as her movements and mark-making changed. Looking at the 'finished product' could not possibly have given anyone an insight into this creative process. Cox also illustrated in her piece how the marks made by a child can be changed as external events affect the child's thinking, and she illustrates this point by talking of a child who produced three arched lines and called them first a rainbow, but when a child close by sneezed, the child changed his label to 'a sneeze'. Transformations occur on different levels and children play with the marks they make or the models they create just as they play with words. A mark made in what might be regarded as the 'wrong' place can be explained by the child as part of a joke or a story or a play on reality. Cox is interested in the monologues she heard the children use (as in the example of Leanne above) and feels that they do not reflect the child trying to justify a drawing that is not visually accurate or pleasing but just to explore the same idea or ideas through another mode - i.e. spoken language. We are back to the idea of investigation or exploration involving different modes of representation.
