Young Children’s Inductive Generalizations about Similarities between Siblings or Classmates

Abstract

This study investigated 3-to 5-year-olds' inductive generalizations about similarities between siblings. Children were presented with contrasts in appearance and either sibling or classmate status and asked to generalize either biological properties or behaviors. Performance did not differ from chance for judgments about siblings, but children generalized on the basis of appearance more than classmate status. Thus, young children do not necessarily expect siblings to share biological and behavioral characteristics, but do regard sibling status as different from an arbitrary social relationship such as classmate status.
