The numerical distance effect (NDE) is an important tool for probing the nature of numerical representation. Across two studies, we assessed the degree to which the NDE relates to one's performance on spatial tasks to investigate the role of spatial processing in numerical comparison and, by extension, numerical cognition. We administered numerical comparison tasks and a variety of tasks thought to tap into different aspects of spatial processing. Importantly, we administered both the simultaneous comparison task and the comparison to a standard task, given claims that the NDEs that arise in these two tasks are different. In both studies, the NDEs elicited when comparing simultaneously presented numbers were more strongly negatively correlated with an individual's performance on the spatial tasks than the NDEs elicited when comparing numbers to a standard. The implications of these data for our understanding of numerical comparison tasks and numerical cognition more generally are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

数值比较是空间性的 - 除非它不是。


数值距离效应 （NDE） 是探索数值表示性质的重要工具。在两项研究中，我们评估了濒死体验与一个人在空间任务中的表现的关系程度，以研究空间处理在数值比较中的作用，进而在数值认知中的作用。我们管理了数值比较任务和各种被认为涉及空间处理不同方面的任务。重要的是，我们同时管理了同步比较任务和与标准任务的比较，因为声称这两项任务中出现的濒死体验是不同的。在这两项研究中，比较同时呈现的数字时引发的濒死体验与个人在空间任务上的表现的负相关程度比将数字与标准进行比较时引发的濒死体验更强。讨论了这些数据对我们理解数值比较任务和更普遍的数字认知的影响。（PsycInfo 数据库记录 （c） 2024 APA，保留所有权利）。
