摘要Numerical information can be conveyed by either symbolic or nonsymbolic representation. Some symbolic numerals can also be identified as nonsymbolic quanities defined by the number of lines (e.g., I, II, III in Roman and (sic), (sic), (sic) in Japanese Kanji and Chinese). Here we report that such multi-representation of magnitude can facilitate the processing of these numerals under certain circumstances. In a magnitude comparison task judging 1 to 9 (except 5) Chinese and Arabic numerals presented at the foveal (at the center) or parafoveal (3 degrees - left or right of the center) location, multi-representational small value Chinese numerals showed a processing advantage over single representation Arabic numerals and large value Chines numerals only in the parafoveal condition, demonstrated by lower error rates and faster reaction times. Further event-related potential (ERP) analysis showed that such a processing, such as N1 or P2p. Instead, the difference was found much later in a N400 component between 300-500 msec over parietal regions, suggesting or accessing or accessing mental number line when lacking attentional resources. These results suggest that there could be three stages of number processing represented separately by the N1, P2p and N400 ERP components. In addition, numerical information can be represented simultaneously by both symbolic and nonsymbolic systems, which will facilitate number processing in certain situations.
