摘要：This study analyzed physical knowledge displayed in the utterances of 10 Korean children 23 . 76 months of age. Utterances were blocked into four -month time periods,except the first two months and classified into 5 categories including properies of physical objects and materials,friction,buoyancy, gravity,and the motion of physical objects. All five types of physical expressions were found in the data of the earliest period the percent age of the properties and motion was higher than the percent of friction,buoyancy,and gravity. Data suggested two transitional points of change in physical knowledge : 2-year-old's descriptions were based only on perceptually salient physical features 3- to 4-year-olds described only end-state results while children older than 4 included systematic causality..
