But the limitation of this study field is that representation of concretized numbers is nearly ignored. SNARC effect revealed that subjects responded to large numbers faster with the right hand than with the left hand, whereas the reverse held true for small numbers. Based on the hypothesis of mental number line, the researchers developed a number line estimation task to explore the law of number representation and development. In this task, the subjects are presented with a line with numbers on both ends (e.g., 0 and 100), and ask the subjects to determine the position of the number (e.g., 70) on the line. At present, there are two different views on the processing mechanism of time, space and quantity. The first point of view proposes that the processing of the three kinds of information share the common processing mechanism. The representative theory of first point of view is ATOM (A Theory Of Magnitude) proposed by Walsh (2003), which considers that the processing of time, space and quantity depends on a single representation mechanism. Another view is the multi representation system, which holds that the processing of time, space and number are domain-specificity, and each kind of information processing has the unique representation and transformation mechanism. Number representation and processing are handled by a non-abstract system, which processes numbers according to specific situations. So, a lot of studies in the past utilizing the number line estimation task almost ignored the concretized meaning of numbers, that is to say ignoring the difference between pure numbers and concretized numbers. In current study, Siegler’s(2003) number line estimation task is used as prototype to explore the change of number representation from grade two to grade six under the condition of concretized time by appending time unit (秒, 小时) to pure numbers. When the number is given meaning, the numerical semantic information is
