摘　　要：Cohen于2011年提出了无界数字线估计任务,诸多研究表明该任务克服了传统有界数字线估计任务的局限,能够反映更加纯粹的数字表征本质。然而,无界数字线估计的模型与策略与有界数字线估计的异同,还有待检验。文章分别对有界和无界数字线估计任务中的数字表征模型和估计策略进行梳理,分析两种任务中数字线表征模型以及估计策略发展与转变的相似与分离,并进一步推测估计策略与表征模型之间的关系,以期为数字认知的相关研究提供参考。As the unbounded number line estimation task was proposed by Cohen in 201l,more and more studies have shown that this task overcomes the limitations of the traditional bounded number line estima-tion task,and it is able to reflect a purer quantitative representation.However,the similarities and differ-ences between the model and strategy of unbounded number line estimation and bounded number line esti-mation are yet to be scrutinized.This article respectively sorts out the number representation models and estimation strategies in the bounded and unbounded number line estimation tasks and analyzes the similari-ties and differences of the number line representation models as well as the development and transformation of estimation strategies in the two tasks,and further,speculates on the relationship between the estimation strategy and the representation model,in order to provide a reference for the related research of number cognition and number line representation.
