学習者の文発話プラン : 句のタイプとプレビューの影響

抄録

The present study examined the question of whether L2 learners' scope of sentence planning varied according to the type of the subject phrase containing double nouns: coordinated noun phrase (e.g., "the dog and the table") and prepositional noun phrase (e.g., "the dog above the table"). An experimental technique in psycholinguistics, preview, was applied to investigate the extent of planning before speech onset and to clarify the magnitude of the effect of advance access to each noun in the subject phrase. The results revealed that Japanese learners of English at college level planned not only the head noun of a prepositional phrase subject (i.e., "the dog") but also the noun in the prepositional modifier (i.e., "above the table") prior to speaking. This result is in sharp contrast to the scope of planning by speakers of L1 English revealed by previous studies. We assumed that learners took the noun in a prepositional modifier into the scope of planning because of interference from the opposite word order between English and Japanese. Finally, two pedagogical methods are proposed to enable learners to plan a sentence following the word order in English.
