| 摘 要： | 数字线估计是估计数字在线段上的位置。采用行为实验和电生理法研究被试、材料和环境因素对数字线估计的影响，构建了基于对数、等级可变性、线性、幂函数等单一表征的早期模型和幂函数模型及基于多重假说的叠波理论，尽管这些理论都能解释表征的发展特点，但叠波理论能更好地解释数字线估计的心理机制。

| Abstract: | Number line estimation is asked to estimate a position on a number line.Researchers use behavioral procedures and electrophysiological methods to investigate influencing factors such as subjects,material and environment.Early models and power function based on single representation and overlap theory based on multiple representation.Though these theories can explain the developmental feature of representation,but overlap theory can better explain the number line estimation’s psychological mechanism. |
