title: Intraverbal acquisition of semantic concepts by preschoolers.
abstract: Intraverbal learning is a process through which semantic knowledge is acquired from purely linguistic information. The concern of this study is to investigate the role of intraverbal learning in the preschool-aged child's acquisition of semantic concepts. Three- and 4-year-old children were either shown pictures illustrating novel concepts or they were told verbal definitions of novel concepts, the definitions containing information about key physical and functional properties. An additional manipulation consisted of including or omitting information about the superordinate category membership of the concept. Concept acquisition was assessed via a battery of comprehension tasks; these tasks assessed both referential and formal knowledge of the concepts. Results indicate a correspondence between the type of information received and the type of knowledge acquired, with intraverbal information resulting in broader knowledge than pictorial information. Purely pictorial information was associated with referential knowledge only, while intraverbal information enhanced both referential and formal knowledge.
