1. With 130 nursery-school children between the ages of one and three years (74 boys, 56 girls between 18 and 41 months) as subjects, we conducted "guardian observations and eating surveys of mealtime in households, " "taste sensitivity tests, " and "infant development surveys, " investigating the effects of eating behavior in the initial stages of infancy on the sense of taste and mental development. We found no statistically significant correlation between the eating situation in infancy and the taste sensitivity of the children, except sensitivity to salty flavors. Between the eating situation of theinitial stages of infancy and mental development, however, a significant correlation was observed in four to five among a total of six developmental categories. A healthful eating situation in infancy had a positive effect on mental development (e.g., basic habits, language formation, language comprehension). From this information, it seems that eating habits at home in infancy exert alm
ost no influence on taste sensitivity, except for salty flavors, but it is possible that there may be an effect on mental development.
2. We twice visited the homes of 33 children between the ages of one and two years (20 boys, 13 girls between 18 and 29 months), during which time we observed eating circumstances (language forination, expressions when eating, and manner of eating, etc.), taking video footage of thesituation. With these children as well, we conducted "taste sensitivity tests, " and "development and disposition evaluations." With regard to the video footage we took of the eating circumstances, we analyzed language for mation, facial expressions, and so on, and investigated the relationship between "language formation, " "taste sensitivity, " and "disposition." In such eating circumstances, we observed a mutual correlation between the mother's expressions of praise and the child's disposition (moodiness, approachability, adaptability, level of response, quality of mood).
2. 年齢1〜2歳の家庭児33名(男児20名、女児13名;月齢18〜29か月)について、われわれが各家庭を2回訪問し、食事場面の観察(発話・食事時の表情・食事のし方等)を行ってビデオ収録した。これらの児についても、「味覚感受性検査」「発達検査ならびに気質検査」を実施した。ビデオ収録した食事場面については、発話ならびに表情等を分析し、「発話」「味覚感受性」「気質」の相互関連についても検討した。食事場面における母親の賞賛発話出現状況と気質(周期性、接近性、順応性、反応強度、気分の質)との間には相互関係が認められた。 Less
