ABSTRACT
The previous chapter demonstrated that children solved the perspective problem, that of selecting the perspective seen from another person’s point of view, by identifying distinguishing features of the display and labelling, by means of spatial predicates, the relation between that feature and the observer. These spatial relations have in other chapters been described as observer-referent descriptions. The concern in this chapter is with generalizing that theory to include an account of the form of the spatial relation recruited for the solution to rotation problems. In these problems, a display is rotated, or imagined to rotate, and the child either judges whether two depictions are the same object in different orientations, or predicts a correct depiction of a given display after a particular rotation.
