Symmetric objects are known to be perceived easier than asymmetric objects, because less information has to be processed. Therefore, symmetric objects are often used for spatial tasks. However, in perspective-taking the use of symmetric objects can also cause difficulties, as two side-views of these objects are mirror-images of each other. To examine this influence, 95 children at the beginning of first grade were asked to solve a systematically varied set of tasks in interview sessions. It was assumed that they have more difficulties to solve the tasks with symmetric objects than with asymmetric ones. Against expectation, this effect could not be confirmed based on the number of correct answers. However, the types of errors and the children's explanations show the difficulties of perspective tasks with symmetric objects. [For the complete proceedings, see ED597799.]
