On the Development of Infants Behavior and Personality at the Stage of Pre-Speech (IV)

第3報で報告したように、乳幼児の前言語的行動を親と保母が見た場合に、両者共に評価が高いグループは前言語的行動の発達がよかった。それを、さらに実証するために、太田昌孝、他(東大精神科)の表象能力のStage評価により、前言語的行動の中核をなす表象能力の調査を行い、表象能力を数値化して検討してみた。1989年5月に、昨年の調査の対象児で本年16ヵ月から30ヵ月になった大阪市と池田市の保育園に在籍している196名を対象とした。その結果、親も保母も共に評価が高いグループは表象能力のStage評価も高く、これにより言語発達の予測が容易であることが推測できた。According to the analysis of 3rd survey, the group of infants who showed favorable pre-speech developments had similar evaluation of the development between their parents and nurses. In order to verify the above, we further investigated the infants' ability of presentation which is the core of pre-speech development, and analysed the quantified presentation behavior. For this survey, we took the data from the same 196 infants as last year's in both Osaka and Ikeda cities. They were from 16 months to 30 months old in May, 1989. In this survey we proceeded on the assumption that the development of infants' speech acquisition would be quicker and more normal when the observations and evaluation of parents and those of nurses at schools are close or similar in terms of the evaluation of presentation
