以前的研究已经发现了数字处理和算术性能之间的相关性。视觉感知已经被证明是这两者之间的共同认知机制;然而,这些研究主要集中在儿童身上。目前尚不清楚数字处理和算术性能之间的关联是否仍然存在随着个人算术性能的发展。因此,在成年人中,尚未充分研究视觉感知在数字处理和算术表现中的潜在作用。对于这项研究,研究人员共选择了205名平均年龄为22岁的成年参与者.对成年人进行了算术测试,数字比较,和视觉图形匹配。精神旋转,选择反应时间,非语言智力被用作认知协变量。结果表明,成年人的数字比较与他们的算术表现相关,即使在控制了年龄和性别差异以及一般认知过程之后。然而,在控制视觉图形匹配后,数字比较和算术性能之间的既定关联消失了。这些结果支持视觉感知假设,通过视觉图形匹配测量的视觉感知可以解释数字比较和算术性能之间的相关性。这表明,即使对于成年人来说,视觉感知能力是数字处理和算术性能的潜在组成部分。
Previous studies have found a correlation between numerosity processing and arithmetical performance. Visual perception has already been indicated as the shared cognitive mechanism between these two; however, these studies mostly focused on children. It is not clear whether the association between numerosity processing and arithmetical performance still existed following the development of individual arithmetical performance. Consequently, the underlying role of visual perception in numerosity processing and arithmetical performance has not been sufficiently studied in adults. For this study, researchers selected a total of 205 adult participants with an average age of 22years. The adults were administered arithmetic tests, numerosity comparison, and visual figure matching. Mental rotation, choice reaction time, and nonverbal intelligence were used as cognitive covariates. Results showed that numerosity comparison of adults correlated with their arithmetical performance, even after controlling for age and gender differences as well as general cognitive processing. However, after controlled for visual figure matching, the well-established association between numerosity comparison and arithmetic performance disappeared. These results supported the visual perception hypothesis, that visual perception measured by visual figure matching can account for the correlation between numerosity comparison and arithmetic performance. This indicated that even for adult populations, visual perceptual ability was the underlying component of numerosity processing and arithmetic performance.
