Abstract

近年, 学習障害を持っている知能発達障害の小児は、知能指数(IQ)テストによって発見される。脳の成長率は、出生から3歳までの間に約80%、5歳になるまでに90%、そして6歳で100%に達すると言われている。特に脳の成長の大部分は出生からの3年間と言われている。本研究では、顔画像を呈示した時の小児の反応を解析し、知能発達障害小児の早期検出を試みる。もし、知能発達障害の小児を3歳になるまでに発見することができれば、脳が完全に発達する前に、リハビリを行うことができ、脳障害の回復の可能性はより高くなる。実験データから、顔画像のカテゴリーによって結果が異なることがある。被験者の母親の表情を呈示すると、被験者が容易に情報を認識・理解し表情を表出することができる。

Recently, mentally retarded children with learning disabilities are detected when children can be evaluated by their intelligence quotient(IQ). Many results have shown that between birth and the age of three, brain development almost reaches 80%, before the age of five reaches almost 90% and maximum efficiency before six years old. It is in the first three years of human life that the brain has most of its growth. In this study, we try to detect mentally retarded children by analyzing their facial expressions after displaying certain face picture images. If mentally retarded children could be detected before the age of three, the correct treatment could be prescribed at an early stage before the brain completely develops. Therefore the possibility for the brain recovery is higher and also could increase the child's ability. From this study, we can conclude that children easily recognize and understand information from familiar sources, like their own mother's facial expressions than from unknown sources, like from unknown woman.
