Abstract: Numerous studies have shown that finger counting habits have effect on number processing performance. Two types of finger configurations were tested: canonical and non-canonical configurations. Meanwhile encoding mode are also different. Canonical configurations should activate a place coding representation, which automatically activate number semantics. Whereas non-canonical configurations belong to summation coding, which activates number perceptual. Under the Chinese culture context, the finger numeral representation has its special connotation, especially the representations of larger numbers. In order to clarify the peculiar effect that the finger numeral configurations on the number recognition in Chinese culture context, the present study was conducted. It was hypothesized that canonical configurations would be processed as symbolic stimuli, whereas non-canonical ones would be processed as non-symbolic stimuli. Two experiments were conducted in the present study. The Experiment 1 adopted the distance priming paradigm, and examined the influence of different finger numeral configurations of single hand on the small number(1~5) of cognitive processing; Experiment 2 used Chinese finger numerical representations as canonical configurations, continuing to exam that different combinations of both hands impact the large number(5~9) of cognitive processing. The results showed that: The two types of finger configurations clearly activate two types of magnitude representations in Exp.1. For canonical configurations, we found a strong main distance effect for both the left and right sides of the regression line. This pattern suggests the activation of a place coding representation, and it appears semantic feature. For non-canonical configurations, we found a distance effect only for the right side of the regression line when targets were larger than primes, but a flat distance effect for the left side in which targets were all equally activated. This pattern suggests the activation of a summation coding representation, and it appears perceptual feature. It was observed that the two types of finger configurations clearly activate the same of magnitude representations in experiment 2, which means that the place coding representation was adopted under two different conditions, finger numerical representation appears semantic feature. The results above supports the embodied numerosity theory and computational model. In conclusion, these results indicates that canonical numerical finger configurations appears semantic feature and non-canonical numerical finger configurations transform perceptual to semantic feature by embodied numerosity theory and computational model under Chinese cultural context.

摘要： 采用距离启动范式，考察中国文化背景下不同手指表征方式对数量表征能力的影响。实验首先验证单手表征中不同手指数量表征方式对小数字（1～5）认知表征的影响；实验2则进一步采用中国人特有的单手手指表征，考察其对大数字（5～9）认知表征的影响。结果表明，小数字中出现了标准手指表征方式语义层面的位置编码、非标准手指表征方式知觉层面总和编码的激活；但大数字中两种手指表征方式均出现了语义层面位置编码的激活。此结果与计算模型理论一致，说明当手指数量从少到多变化时，标准手指表征方式为语义性的符号数量表征；而非标准手指表征方式由知觉性的非符号向语义性符号数量表征过渡。
