以44名小学六年级儿童与40名大学生为被试,通过0-1和1/100-1/10两种数字线的NP（数字位置）和PN（位置数字）估计任务系统考察儿童与成人的分数估计的表征方式。结果显示：（1）儿童和成人在0-1数字线的NP和PN任务上都呈线性表征,但在1/100-1/10数字线下,两组被试在NP任务上却呈对数表征,在PN任务上呈指数表征;（2）NP任务的错误百分比均高于PN任务,且儿童在两数字线下的准确性均明显低于成人。

44 sixth-graders and 40 college students were tested by Number-Position task （NP） and Position-Number task （PN） on 0- 1 and 1/100 -1/10 number lines to explore children＇s and adults＇ representation patterns of fractions estimation. Results showed that ： 1 ） Two groups followed a linear pattern in both NP and PN tasks on 0 - 1 number line, and followed a logarithmic pattern on NP task and an exponential pattern on PN task on 1/100 - 1/10 number line. ; 2） the percentage of error for NP task was higher than PN task for children and adults, and sixthgraders made more error than the adults did on the 0 - 1 and 1/100 - 1/10 number lines.
