Development and Formation of Metalinguistic Knowledge on Phonetic Unit

本研究旨在考察使用非普通日语的婴幼儿和学龄前儿童日语语音单位元语言知识的发展过程。首先，为了收集儿童方言使用的基础数据，我们对幼儿园和小学的语码转换进行了会话分析。我们在山形仙奈区购买了一堂从幼儿园到小学一年级的课程，并制作了120小时的幼儿教师语料库和同伴对话语料库。孩子们使用方言形式，从普通日语切换到方言日语。第二，为了研究儿童对语音单位的有意识操作，我们创新了一种新的实验方法，让儿童听到常见的日语或方言形式，并选择一张图片卡来代表其中一种声音刺激。研究发现，汉字的发音与语音分析的元语言知识、方言意识和日语共同差异相关。

This research is to investigate the developmental process of metalinguistic knowledge on Japanese ponetic unit in infants and preschoolers, who use dialectal non-common Japanese.First, for gathering basic data on dialect use in children, we conducted a conversational analitic research on the code switching in kindedergarden and elementary school. We purchased one class, in Syonai district yamagata, from kindergarden to first grade of elementary school and made 120 hours corpus on child-teacher and peer conversation transcription. Children use dialectal forms and switch from common to dialctal Japanese. This switching is resourse for displaying and understanding the formality of conversation settings.Second, for investigation of conscious operation on phonetic units, we innovated a new experimental method in which children hear common Japanese or dialectal form and select one picture card which represened by either of the voice stimulus. We find that acuisition of KANA characters corelated with the metalinguistic knowledge on phonetic analysis and conscious awareness on dialect and common Japanese difference.
