利用大小一致性效应（SiCE）证明了2位数的自动处理。SiCE表示在相关（物理）维度上比较两个数值和物理上不同的数字时，对不相关（数字）维度的处理。SiCE受到单位位数和十进位数之间兼容性的影响，但不受数字的全局大小的影响。总之，这些结果表明，自动处理的是2位数分量的大小，而不是整数分量的大小。最后，与单位位数相比，十进位位数的大小对语义语义的影响更大，说明十进位的句法作用得到了体现。讨论了这些结果对理解数值表示的意义。
Automatic processing of 2-digit numbers was demonstrated using the size congruency effect (SiCE). The SiCE indicates the processing of the irrelevant (numerical) dimension when 2 digits differing both numerically and physically are compared on the relevant (physical) dimension. The SiCE was affected by the compatibility between unit and decade digits but was unaffected by the global magnitude of the numbers. Together these results suggest automatic processing of the magnitudes of the components of the 2-digit numbers but not of whole numbers. Finally, the SiCE was affected more by the magnitude of the decade digits compared with the unit digits, indicating that the syntactic roles of the digits were represented. The implications of these results for understanding the numerical representations are discussed.
