Previous research on the development of intuitive statics has revealed that preschoolers’ ability to judge the stability of asymmetrically shaped objects is severely limited ( Krist, 2010 ). To overrule the objection that this limitation is caused by extraneous task demands, the original task was simplified by eliminating the need to judge the stability of varied objects consecutively in a series of trials. Three- and 4-year-old children (N = 65) were presented with L-shaped blocks either sufficiently supported by a platform or not. In six experimental trials, children had to judge whether the respective block would fall if released. In agreement with previous results, children exhibited great difficulties judging the stability of the asymmetrically shaped objects. Only 4-year-olds performed reliably above chance, whereas 3-year-olds answered at a chance level. It could thus be confirmed that preschoolers’ difficulties judging the stability of asymmetrically shaped objects are not merely due to extraneous task demands.
