| Outline of Final Research Achievements |
We collected data on vocabulary development based on psychological knowledge and analyzed a vocabulary development mechanism for children using data processing methods. Based on our analysis, we achieved the following in vocabulary development:
1.We collected cross-sectional data on about 900 people over a three-year span. 2.We reached the following conclusions: (1) a strong correlation exists between two regions: Kyoto and Tokyo, indicating almost no regional differences; (2) children with and without developmental disabilities whose vocabularies are about the same size tend to use similar words; (3) we found no significant differences between males and females; (4) in younger children, the effects of children abuses from their parents on vocabulary development appear before they entered the residential care institutions, and this effect decreases as the size of the acquired vocabulary increases. 3.We proposed a small vocabulary checklist to estimate the ability of young children.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、語彙発達の過程が、男女、障害や、乳児院入居の区別になく、語彙数にだけに強く依存し、統一的に解釈できることを発見したことは、学術的、社会的に意義が極めて大きい。これにより、語彙数を基準として統一的に、語彙発達の機構の分析を行うことことができ、人間の言語獲得プロセスを解明する大きな手がかりとなる。また、発達の時間的な遅れを観測することにより、様々な障害の原因究明や、障害に対する学習手法の開発、生活環境に対する適応的な学習手法の開発など、様々な分野で新しい研究領域を広げることにつながる。
