Children (aged five-to-six and nine-to-ten years) and adults rated the acceptability of well-formed sentences and argument-structure overgeneralization errors involving the prepositional-object and double-object dative constructions (e.g. "Marge pulled the box to Homer/*Marge pulled Homer the box"). In support of the entrenchment hypothesis, a…

Purpose: The study of auxiliary acquisition is central to work on language development and has attracted theoretical work from both nativist and constructivist approaches. This study is part of a 2-part companion set that represents a unique attempt to trace the development of auxiliary syntax by using a longitudinal elicitation methodology. The…

Analyzed correct wh-question production and subject-auxiliary inversion errors in one child's wh-question data. Argues that two current movement rule accounts cannot explain patterning of early wh-questions. Data can be explained by the child's knowledge of particular lexically-specific wh-word+auxiliary combinations, and inversion and universion…

Many current generativist theorists suggest that young children possess the grammatical principles of inversion required for question formation but make errors because they find it difficult to learn language-specific rules about how inversion applies. The present study analyzed longitudinal spontaneous sampled data from twelve 2-3-year-old…

This study investigated different accounts of children's acquisition of non-subject wh-questions. Questions using each of 4 wh-words ("what," "who," "how" and "why"), and 3 auxiliaries (BE, DO and CAN) in 3sg and 3pl form were elicited from 28 children aged 3;6-4;6. Rates of non-inversion error ("Who…
