Two levels of inferential behavior in young children.

5- and 6-year-old children made inferences about the spatial locations of animals and people in a series of 3 experiments. The tasks employed manipulable models to represent the spatial relations involved and were made as simple as possible. 2 levels of inferential behavior were found. The first constituted the ability to draw an inference consistent with information given, but with minimal understanding of the way in which inferences can assist in decisions between alternative outcomes. At the second level, children succeeded in discriminating inferences which were logically necessary from those which were merely consistent with the premises. Most 5-year-olds were at the first level, most 6-year-olds at the second level. 2 criteria for the identification of young children's behavior as inferential were established, and the results of the present study were discussed in terms of recent related work with both younger and older children.
