数字加工的特点是距离和大小效应，但符号数字比非符号数字表现出更小的影响。符号处理和非符号处理之间的差异既可以用不同类型的底层表征来解释，也可以用同一类型底层表征中的参数差异来解释。我们进行了一项启动命名研究来调查这个问题。操作了预充和目标格式（数字或点的集合）以及预充和目标值之间的数值距离。定性不同的启动模式，观察到的两种格式，显示的基本表征不同的种类：数字激活的心理数字表征的地方编码类型，而集合的点激活的总和编码类型的数字表征。(C)2006 Elsevier B.V.保留所有权利。
Number processing is characterized by the distance and the size effect, but symbolic numbers exhibit smaller effects than non-symbolic numerosities. The difference between symbolic and non-symbolic processing can either be explained by a different kind of underlying representation or by parametric differences within the same type of underlying representation. We performed a primed naming study to investigate this issue. Prime and target format were manipulated (digits or collections of dots) as well as the numerical distance between prime and target value. Qualitatively different priming patterns were observed for the two formats, showing that the underlying representations differed in kind: Digits activated mental number representations of the place coding type, while collections of dots activated number representations of the summation coding type.
