Children's ability to infer consequences from sentences automatically was assessed in two cued recall experiments. Seven- and eight-year-old children and adults served as subjects. (JMB)

The purposes of this experiment were: (1) to examine the development of categorical representations by comparing the performance of children of various ages to adults, and (2) to compare the internal representations of basic level and superordinate categories.
