The Development of Strategies for Coordinating Spatial Perspectives of an Array
The question now arises as to whether or not some similar representations and procedures may be used to solve a complex perspective task such as Piaget and Inhelder’s three mountain task. In their task, the display was complicated in two ways. First, the items themselves, that is, the mountains, were unfeatured objects, that is they have no canonical front, back and so on, and as we have seen in the previous chapter, the problem is more dif ficult for unfeatured than for featured objects. Second, the display con tained not a single object, as in the preceding chapter, but an array of ob jects, in this case, three mountains.
