Some remarks on the psycholinguistic relevance of LTAGs.
Alexandra Kinyon · 1999
In this paper we discuss the psycholinguistic relevance of a "surfastic" TAG-based theory of syntax (Abeill 91, Abeill and al. 00a). We show that widely accepted parsing preferences can be elegantly formulated on LTAG derivation trees. We sketch a processing model which allows to predict Garden-Path phenomena and sheds a new light on some psycholinguistic results concerning the existence of Wh traces 1 . 1 Introduction Lexicalized Tree Adjoining Grammars (LTAGs) have been shown to be motivated from a computational point of view : it is a mildly context sensitive formalism and therefore parsable in polynomial time (cf Vijay-Shanker 87). It is also motivated from a linguistic point of view, especially because it allows to handle elegantly crossed and long distance dependencies (cf Abeill 91). This has led to the development of wide-coverage grammars, for English (Xtag group 95) and for French (Abeill and al. 99). LTAGs were also argued to be relevant from a psycholinguistic...
