采用快速数字大小分类范式，以小学六年级、初中二年级和大学生为被试，探讨了负数在心理数字线上的表征方向及其发展性问题。结果表明，对于小学六年级和初二学生，负数在心理数字线上是按其实际数值大小表征的，在心理数字线的左侧表征实际数值小的负数，右侧表征实际数值大的负数。支持数量扩展假设；对于成人，负数在心理数字线上是按其绝对值大小表征的，在心理数字线的左侧表征绝对值小的负数，右侧表征绝对值大的负数，支持基于规则假设。
採用快速數字大小分類範式，以小學六年級、初中二年級和大學生為被試，探討瞭負數在心理數字線上的錶徵方嚮及其髮展性問題。結果錶明，對于小學六年級和初二學生，負數在心理數字線上是按其實際數值大小錶徵的，在心理數字線的左側錶徵實際數值小的負數，右側錶徵實際數值大的負數。支持數量擴展假設；對于成人，負數在心理數字線上是按其絕對值大小錶徵的，在心理數字線的左側錶徵絕對值小的負數，右側錶徵絕對值大的負數，支持基于規則假設。

This paper adopts the speeded magnitude classification paradigm in order to investigate developmental problems of the spatial representation of negative number.The participants include sixth grade pupils of primary school, second grade pupils of junior high school and university students.The investigated results show:(1) for sixth grade pupils of primary school and second grade pupils of junior high school, negative number is mapped onto mental number line according to their numerical value, from the small value on left to large value on right;This is in keeping with the expanded magnitude hypothesis.(2) But for adult, negative number are mapped onto mental number line according to their absolute value, from small absolute value on the left to large absolute value on the right;This is keeping with the rule-based hypothesis.
