The Learning of Surface Structure Clues to Deep Structure by a Puppet Show Technique

Abstract

Fifty-six children were classified in terms of their developmental level on the linguistic structure “John is easy/eager to please”, and an experiment was carried out teaching them “new” (nonsense) words in related transformations by a puppet show technique. These transformations serve as frames for differentiating those new words which indicate a surface structure derived from a transformed deep structure, from those which do not. Results showed that children used different strategies at different developmental levels. Of children who did not use fixed strategies, only children who had correctly performed on all normal adult words (“Passers”) were able to learn which deep structures were called for by some of the new words; all other groups performed at chance levels on all types of new words. However, even these Passers performed correctly only on words given in structures indicating that the tested structure was to be treated as a transformation. The possibility of a language-learning principle related to the marked/unmarked distinction in natural languages is discussed.
