Study on Geographical and Social Dynamics of the Modern Tohoku Dialects

本研究旨在对现代东北方言进行概括性的考察，特别关注地理和代际动态。“声门图”(年龄-区域图)技术，即在一张纸上可视化一个线性区域的年龄差异，是研究语言过程中变化的最合适的方法。这项技术已经在日本大部分地区得到应用，但北部除外。在对东北和北海道地区进行联合研究的基础上，明确了全日本方言扩散的模式。所有获得的数据都被输入计算机，并公布了69个地区229名举报人的300多张图表。所有原始数据和相关材料将在稍后以光盘的形式公布。

This study aims at a general survey of the modern Tohoku dialects paying special attention to geographical and generational dynamics. The technique of "glottogram" (age-area graph), visualizing age differences of a linear area on a sheet of paper, is the most appropriate method to study the linguistic change in progress. This technique has been applied in the most part of Japan, except the northern part. On the basis of the present joint study of Tohoku and Hokkaido areas, the patterns of dialectal diffusion of the whole Japan were made clear. 'A11 the acquired data were put into computer, and more than 300 graphs showing 229 informants of 69 localities were made public. All the raw data and related materials will be made public later in the form of CD-ROM.
