title: The development of inversion in wh-questions: a reply to Van Valin.
abstract: Van Valin (Journal of Child Language 29, 2002, 161-75) presents a critique of Rowland & Pine (Journal of Child Language 27, 2000, 157-81) and argues that the wh-question data from Adam (in Brown, A first language, Cambridge, MA, 1973) cannot be explained in terms of input frequencies as we suggest. Instead, he suggests that the data can be more successfully accounted for in terms of Role and Reference Grammar. In this note we re-examine the pattern of inversion and uninversion in Adam's wh-questions and argue that the RRG explanation cannot account for some of the developmental facts it was designed to explain.
