已有研究中数字线估计任务几乎都使用纯数字。本研究以二到六年级儿童为被试,采用纯数字任务和赋义数字任务来探索赋义表象对数字表征形式的影响。结果表明,对0~1000的数字赋义后,对数模型的解释力上升,而线性模型的解释力下降;表象大小对于赋义数字的估计影响显著,大表象赋义提高了对数模型解释力而降低了数字估计的准确性,小表象的影响比较微弱。 Almost all of the digital line estimation tasks used in previous studies use pure numbers. In this study, children from grade two to six were selected as subjects, and the pure digital task and the number assignment task were used to explore the influence of the appearance of the meaning on the digital representation. The results show that after the number of 0 ~ 1000, the explanatory power of the logarithmic model increases and the explanatory power of the linear model decreases; the size of the image has a significant effect on the estimation of the meaningless numbers, and the large appearance increases the explanation of the logarithmic model However, the accuracy of the numerical estimation is reduced, and the impact of the small appearance is relatively weak.
