探讨儿童在数字线估计任务中心理长度的发展及其对数量表征模式的影响。选取7-9岁儿童共109名进行数字线估计任务测试,设置了10cm和20cm两种长度条件,要求儿童完成根据位置判断数字任务(position to number,PN任务)。结果表明儿童在数字线PN任务中存在心理长度,且7岁儿童心理长度的范围超过10,随着儿童年龄的增长,他们的心理长度范围不断缩小;心理长度范围影响儿童的表征模式,随着心理长度范围的缩小,儿童的数字线表征出现从指数模式到线性模式的变化趋势;与表征模式的发展趋势一致,儿童估计的精确性随年龄增长逐渐提高。
探討兒童在數字線估計任務中心理長度的髮展及其對數量錶徵模式的影響。選取7-9歲兒童共109名進行數字線估計任務測試,設置瞭10cm和20cm兩種長度條件,要求兒童完成根據位置判斷數字任務(position to number,PN任務)。結果錶明兒童在數字線PN任務中存在心理長度,且7歲兒童心理長度的範圍超過10,隨著兒童年齡的增長,他們的心理長度範圍不斷縮小;心理長度範圍影響兒童的錶徵模式,隨著心理長度範圍的縮小,兒童的數字線錶徵齣現從指數模式到線性模式的變化趨勢;與錶徵模式的髮展趨勢一緻,兒童估計的精確性隨年齡增長逐漸提高。

A total of 109 7-to 9-year-old children were selected to take the number line estimation task. The aim was to test how their mental distance,numerical representations,and accuracy of estimation developed with age.The results showed the following: Mental distance did exist among 7- to 9-year-old children,and the range of mental distance might exceed 10 for 7-year-old children and gradually disappeared between 7- to 9-year-old;Influenced by mental distance,children's number line representational models changed from exponential to linear;In accordance with the change of representational models,the accuracy of estimation improved with development.
