title: Development of intuitions about support beyond infancy.
abstract: In a series of 3 experiments modeled after infant studies, 3- to- 6-year-old children's intuitive knowledge about support was assessed. Different objects were shown either sufficiently supported or not. Children had to predict whether a block would remain standing on a platform upon release or make perceptual judgments about the possibility of a shown block-on-platform configuration. Overall, performance was strongly age-related and independent of task context. Sensitivity for the amount of contact between object and support was clearly evidenced for each of the age-groups tested and was almost perfect in 5- and 6-year-olds. By contrast, sensitivity for the proportion of an object's volume positioned over the support was only marginally reliable in 3-year-olds and still far from perfect in 6-year-olds. It is concluded that basic intuitions about support undergo distinct developmental change beyond infancy and are not yet fully developed in kindergartners.
