構造的曖昧文における項と付加要素の処理方略の相違 : 日本語の副詞を用いて

Kamide and Mitchell (1999) showed that a dative goal argument is preferably interpreted as an argument of the matrix verb rather than that of the embedded verb when it appears in a structurally ambiguous position. This suggests that reanalysis of the existing structure is not preferred by the parser (RALR: Reanalysis As a Last Resort). However, it has not been proven whether adjuncts would share the same tendency as argument NPs. This study uses adverbs to examine the attachment preference of adjuncts and gives evidence that adverbs, unlike dative NPs, are more likely to be interpreted in the embedded clause. Findings imply that different strategies are used in the processing of arguments and adjuncts.
